Description

Non-Welded Panel Frame for Earthquake Resistance

The present invention relates to an earthquake-resistant, weld-free subframe, and more specifically, to an earthquake-resistant, weld-free subframe that can stably maintain a state of being joined to a finishing panel of a building's exterior wall even when ground vibrations occur due to an earthquake, and that can be installed simply and quickly using a weld-free method.

Unless otherwise indicated herein, the matters described in this identifier are not prior art to the claims of this application, and their description in this identifier is not intended to be deemed prior art.

During exterior building construction, finishing panels are installed on the exterior walls to provide insulation, soundproofing, and aesthetic appeal. These panels are manufactured in multiple sizes suitable for the construction process and placed adjacent to each other, completing the exterior construction.

Finish panel installation typically involves installing a sub-frame on the exterior wall of a building, then securing the finish panels to the sub-frame. The sub-frame consists of multiple frames, and insulation or rainscreens may be installed before securing the finish panels.

In this way, the frame refers to a structure that is first installed on the exterior wall of a building for the installation of finishing panels.

Traditionally, the substructure was manufactured by welding multiple frames together on-site. This on-site manufacturing process created a risk of sparks splashing onto surrounding materials, such as insulation or rainscreens, potentially causing a fire.

Additionally, because the work is done on-site, construction takes a lot of time, and there is a problem that the joint strength between frames may not be consistent depending on the skill level of the worker.

In addition, as the frequency of earthquakes of magnitude 4 or higher occurring on the Korean Peninsula has increased recently, the demand for seismic-resistant structures designed to withstand earthquakes is increasing.

Republic of Korea Patent No. 10-2040407 (announced on November 5, 2019) Republic of Korea Patent Publication No. 10-2024-0109328 (published on July 11, 2024)

The problem to be solved by the present invention is to provide a non-welded earthquake-resistant frame that has no risk of fire by using a non-welding method.

In addition, the present invention aims to provide a non-welded earthquake-resistant frame that can be rapidly manufactured on site and has a constant inter-frame joint strength.

In addition, the present invention aims to provide a non-welded earthquake-resistant frame having an earthquake-resistant design to withstand earthquakes.

The tasks of the present invention are not limited to the above-described contents, and also include various tasks that can be clearly understood by those skilled in the art through the contents described below.

In order to solve the above problem, the present invention proposes, as one embodiment of the present invention, an earthquake-resistant weld-free subframe, comprising: a fixed frame disposed adjacent to an exterior wall of a building and having a fixed portion formed on one side facing a finishing panel; a basic frame structure disposed adjacent to one side of the fixed frame; and a relay bracket, one side of which is fixedly connected to the fixed portion and the other side of which is connected to the basic frame structure so as to be relatively movable with respect to the basic frame structure.

In addition, the relay bracket includes a flange portion fixedly connected to the fixed portion; and a web portion extending from the flange portion and having a long hole formed therein; wherein the relay bracket can be connected to the basic frame structure by a bracket fastening means passing through the long hole.

In addition, the body of the bracket fastening means passes through the hole, and the cross-sectional size of the hole may be larger than the cross-sectional size of the body of the bracket fastening means.

In addition, the present invention may further include a guide bracket that is arranged between the basic frame structure and the web portion to guide the relative movement path of the relay bracket and is fixed to the basic frame structure by the bracket fastening means.

In addition, the present invention may further include a three-dimensional frame structure that is fixedly connected to one side of the basic frame structure facing the finishing panel and is connected to the finishing panel so that the finishing panels are arranged in a plurality and are arranged at an angle to each other.

In addition, the three-dimensional frame structure includes a rear frame forming a straight line; a front frame spaced apart from the rear frame in a curved line and to which the finishing panel is coupled; and an intermediate frame connecting the rear frame and the front frame; wherein the front frame may be formed by connecting a plurality of unit frames having a predetermined length at an angle to each other.

Additionally, the width of one end of the unit frame may be formed to be smaller than the width of the other end.

In addition, the unit frame includes a basic flat plate portion having a predetermined length, side flat plates formed to extend and bend from both sides of the basic flat plate portion, and wing pieces formed to extend inward from the side flat plate portion, wherein dimple grooves are respectively formed at one end, the other end, and between one end and the other end of the side flat plate portion, and the adjacent unit frames can be connected by a non-welding fastening means penetrating the dimple grooves.

Additionally, the screw threads of the dimple groove can be formed simultaneously with the non-welding fastening means penetrating the dimple groove.

In addition, the screw thread of the non-welding fastening means is formed on the body of the non-welding fastening means, and the screw thread of the non-welding fastening means is formed of a first screw thread portion formed from one end of the body of the non-welding fastening means, and a second screw thread portion formed from the first screw thread portion, wherein the pitch of the first screw thread portion may be smaller than the pitch of the second screw thread portion.

In addition, it further includes a pair of support frames each disposed between one end and the other end of a pair of the three-dimensional frame structures, and the pair of the three-dimensional frame structures and the pair of support frames can be fixedly connected to one side of the basic frame structure as a single assembly unit in a pre-assembled and combined state.

FIG. 1 is a drawing showing a state in which a finishing panel is installed on a non-welded earthquake-resistant frame according to one embodiment of the present invention, and FIG. 2 is a drawing showing the non-welded earthquake-resistant frame of FIG. 1.

Referring to FIGS. 1 and 2, the earthquake-resistant non-welded frame (10) of the present invention can stably maintain a state of being coupled to a finishing panel (FP) of a building's exterior wall even when the ground vibrates due to an earthquake, and can be installed simply and quickly in a non-welded manner, and includes a fixed frame (100), a basic frame structure (200), a relay bracket (300), a guide bracket (see FIG. 10, 400), and a three-dimensional frame structure (see FIG. 12, 500).

The fixed frame (100) is installed on the exterior wall of a building and serves as a basic framework, and can be fixedly installed horizontally or vertically relative to the ground. The fixed frame (100) can be manufactured in the form of a hollow square tube. For example, the cross-section of the fixed frame (100) can be rectangular or square.

The fixed frame (100) can be installed horizontally or vertically spaced apart from each other on the exterior wall of a building. The basic frame structure (200) and a pair of fixed frames (100) can be connected by a relay bracket (300).

Figure 3 is a drawing illustrating area A of Figure 2.

Referring to Fig. 3, a fixing portion (110) may be formed on one side of a fixed frame (100). One side of the fixed frame (100) is a portion facing the finishing panel (FP), and the fixing portion (110) is a portion that is fixedly connected to a relay bracket (300), and may include a vertical plate (111) and a connecting plate (112).

The vertical plate (111) is a portion that extends vertically from one side of the fixed frame (100) and may be formed in the shape of a flat plate. The vertical plates (111) may be formed in a plurality of pieces spaced apart from each other. When the vertical plates (111) are formed in a plurality of pieces, the connecting plate (112) may be connected to one end of each vertical plate (111) and supported by the vertical plates (111).

The connecting plate (112) is formed by extending from one end of the vertical plate (111) and is formed in a flat shape so as to be fastened to the relay bracket (300). The connecting plate (112) is in close contact with the flange portion (310) of the relay bracket (300) described below and can be fastened to the flange portion (310) by a bracket fastening means (810). The connecting plate (112) is formed to have the same size as the flange portion (310) so as to increase the adhesion.

The bracket fastening means (810) is formed in a bolt shape, for example, consisting of a head (see FIG. 10, 811) and a body (see FIG. 10, 812), and can fasten the connecting plate (112) of the fixing portion (110) and the flange portion (310) of the relay bracket (300) together with a nut.

Referring to FIGS. 1 and 2, the basic frame structure (200) may be combined with a finishing panel (FP) arranged in a flat shape or combined with a three-dimensional frame structure (500), and may include a horizontal frame (210) and a vertical frame (220). The horizontal frame (210) and the vertical frame (220) may be connected to each other by a non-welding fastening means (see FIG. 16, 820) described below.

Figure 4 is a drawing showing the horizontal frame of Figure 2, and Figure 5 is a drawing showing the horizontal frame of Figure 2 from various angles.

Referring to FIG. 2, FIG. 4 and FIG. 5, the horizontal frame (210) forms the horizontal skeleton of the basic frame structure (200), and can be arranged in multiple pieces spaced apart at regular intervals vertically.

The horizontal frame (210) may include a basic flat plate portion (211), a side flat plate portion (212), and a wing portion (213).

The basic flat plate portion (211) is a basic portion formed in a flat plate shape with a predetermined length, the side flat plate portion (212) is a portion formed by extending from both sides of the basic flat plate portion (211), and the wing portion (213) is a portion formed by extending inwardly from one end of the side flat plate portion (212) of the basic flat plate portion (211).

A through hole (211a) through which a vertical frame (220) passes in the longitudinal direction may be formed in the basic flat plate portion (211). A dimple groove (212a) through which a non-welding fastening means (820) described later passes may be formed in a recessed manner in the side flat plate portion (212). A through groove (213a) may be formed in the wing portion (213) to allow the vertical frame (220) to pass through the through hole (211a) of the basic flat plate portion (211).

The shape of the vertical frame (220) in the form of a frame like the horizontal frame (210), the rear frame (see FIG. 13, 510), the front frame (see FIG. 13, 530), the middle frame (see FIG. 13, 540) of the three-dimensional frame structure (500) described below, the support frame (see FIG. 13, 600), and the reinforcing frame (700) are almost the same as the shape of the horizontal frame (210). These can be formed in a shape almost the same as the horizontal frame (210) including the basic flat plate portion (211), the side flat plate portion (212), and the wing portion (213).

Referring to FIG. 2, the horizontal frame (210) may include an outer horizontal frame (210a) and an inner horizontal frame (210b).

The outer horizontal frame (210a) is positioned adjacent to the fixed frame (100) and is located at the outermost end to be combined with the relay bracket (300), and the inner horizontal frame (210b) is positioned between the outer horizontal frames (210a).

Figure 6 is a drawing showing area B of Figure 2, and Figure 7 is a drawing showing area C of Figure 2.

Referring to FIGS. 6 and 7, the outer horizontal frame (210a) and the inner horizontal frame (210b) have the same overall shape in that they include a basic flat plate portion (211), a side flat plate portion (212), and a wing portion (213), but the shapes at both ends may be different.

Referring to Fig. 4, the overall width (D1) of the outer horizontal frame (210a) may be constant. The width (D2) of both ends of the inner horizontal frame (210b) may be narrower than the middle. That is, one end and the other end of the outer vertical frame (220a), which will be described later, may be inserted into one end and the other end of the outer horizontal frame (210a), respectively. On the other hand, one end and the other end of the inner horizontal frame (210b) may be inserted into the middle of the outer vertical frame (220a).

A break refers to the part between two ends. In a composition expressed as a break, it refers to the part excluding one end and the other end of the composition, occupying most of the length of the composition and located between the two ends.

Figure 8 is a drawing showing area D of Figure 2, and Figure 9 is a drawing showing area E of Figure 2.

Referring to FIGS. 8 and 9, one end and the other end of the inner vertical frame (220b), which will be described later, can be inserted into the stop of the outer horizontal frame (210a). On the other hand, one end and the other end of the inner vertical frame (220b) can be inserted into and pass through the passage hole (211a) of the inner horizontal frame (210b).

Referring to FIG. 2, the vertical frame (220) forms the vertical skeleton of the basic frame structure (200), and can be arranged in multiple pieces horizontally spaced apart at regular intervals.

Referring to FIGS. 7 and 8, the vertical frame (220) may include a basic flat plate portion (221), a side flat plate portion (222), and a wing portion (223). The basic flat plate portion (221) is a basic portion formed in a flat plate shape with a predetermined length, the side flat plate portion (222) is a portion formed to extend from both sides of the basic flat plate portion (221), and the wing portion (223) is a portion formed to extend inwardly from one end of the side flat plate portion (222) of the basic flat plate portion (221).

The basic flat plate portion (221) of the vertical frame (220) may differ from the above-described horizontal frame (210) in that the same configuration as the passage hole (211a) of the basic flat plate portion (211) is not formed.

The side flat plate (222) of the vertical frame (220) can have a dimple groove (222a) formed in a recessed manner through which a non-welding fastening means (820) described later penetrates, similar to the side flat plate (212) of the horizontal frame (210) described above.

The wing section (223) of the vertical frame (220) may have a passage groove (223a) formed in the same manner as the wing section (213) of the horizontal frame (210) described above.

Additionally, the vertical frame (220) may include an outer vertical frame (220a) and an inner vertical frame (220b). The outer vertical frame (220a) is positioned at the outermost end adjacent to both ends of the fixed frame (100), and the inner vertical frame (220b) is positioned between the outer vertical frames (220a).

Referring to FIGS. 6 to 9, the outer vertical frame (220a) and the inner vertical frame (220b) have the same overall shape in that they include a basic flat plate portion (221), a side flat plate portion (222), and a wing portion (223), but their shapes may be different in the middle.

Referring to Fig. 9, the part of the inner vertical frame (220b) that intersects the inner horizontal frame (210b) may have a narrower width than other parts.

Figure 10 is a drawing showing a relay bracket and a guide bracket separated from a basic frame structure.

Referring to FIG. 10, the relay bracket (300) is movable relative to the basic frame structure (200), and one side is fixedly connected to the connecting plate (112) of the fixed part (110) and the other side can be connected to the outer horizontal frame (210a) of the basic frame structure (200).

The relay bracket (300) may include a flange portion (310) and a web portion (320). The flange portion (310) is a portion that is connected to the connecting plate (112) of the fixed portion (110), and the web portion (320) is a portion that is connected to the outer horizontal frame (210a) by forming a long hole (321).

The flange portion (310) may be formed in a flat shape with a shape corresponding to the connecting plate (112). The flange portion (310) is in close contact with the connecting plate (112) and may be fastened to the connecting plate (112) by a bracket fastening means (810).

The web portion (320) may be formed in a flat shape by extending from the flange. The long hole (321) may be formed to be long in the longitudinal direction of the web portion (320). The web portion (320) and the outer horizontal frame (210a) may be fastened by a bracket fastening means (810) passing through the long hole (321).

The cross-sectional size of the long hole (321) may be larger than the cross-sectional size of the body (812) of the bracket fastening means (810). The body (812) of the bracket fastening means (810) is a portion passing through the long hole (321). However, the cross-sectional size of the long hole (321) may be smaller than the cross-sectional size of the head (811) of the bracket fastening means (810).

In addition, a guide protrusion (322) may be formed to protrude on the lower surface of the web portion (320). The guide protrusion (322) is a portion that is seated in the guide groove (420) of the guide bracket (400) described later.

Figure 11 is a drawing showing a state in which the relay bracket and the basic frame structure of Figure 2 are moving relative to each other.

Referring to Fig. 11, the body (812) of the bracket fastening means (810) can move longitudinally within the long hole (321) due to longitudinal vibration of the ground caused by an earthquake. At this time, the head (811) of the bracket fastening means (810) can maintain contact with the web portion (320) of the bracket to the extent that it can slide with the upper surface of the web portion (320) of the relay bracket (300) due to the longitudinal vibration. The longitudinal direction means a horizontal direction with respect to the ground.

As the basic frame structure (200) and the relay bracket (300) move relative to each other in the longitudinal direction, the impact energy caused by the shaking of the ground is converted into kinetic energy and consumed, so that the finishing panel (FP) coupled to the basic frame can remain coupled without being separated.

And an elastic member (not shown in the drawing) may be interposed between the head (811) of the bracket fastening means (810) and the upper surface of the web portion (320) of the relay bracket (300). In this case, the lower surface of the elastic member may be in close contact with the upper surface of the web portion (320), and the upper surface may be in close contact with the lower surface of the head (811).

As the elastic member is elastically deformed by the lateral vibration of the ground caused by an earthquake, the body (812) of the bracket fastening means (810) can move laterally within the long hole (321) due to the lateral vibration of the ground. As the elastic member is compressed by the lateral vibration of the ground and absorbs the impact energy caused by the earthquake, the finishing panel (FP) coupled to the basic frame structure (200) can remain coupled without being separated. The lateral direction means the vertical direction with respect to the ground.

In this way, the present invention can prevent safety accidents caused by separation and falling of the finishing panel (FP) by maintaining a state of connection with the finishing panel (FP) without being damaged even when the ground shakes due to an earthquake.

Meanwhile, the relay bracket (300) may also be fastened to the outer vertical frame (220a). When the relay bracket (300) is fastened to the outer vertical frame (220a), the body (812) of the bracket fastening means (810) may move longitudinally within the long hole (321) due to longitudinal vibration of the ground caused by an earthquake. In addition, as the elastic member is elastically deformed due to transverse vibration of the ground caused by an earthquake, the body (812) of the bracket fastening means (810) may move laterally within the long hole (321) due to transverse vibration of the ground.

Referring to FIG. 10, the guide bracket (400) prevents the upper surface of the basic frame structure (200) from being damaged due to contact with the relay bracket (300) and guides the relative movement path of the relay bracket (300) and the basic frame structure (200), and can be placed between the basic frame structure (200) and the web portion (320) of the relay bracket (300).

The guide bracket (400) may be formed in a flat shape so as to be in close contact with the outer horizontal frame (210a) or the outer vertical frame (220a). A stopper (410) may be formed protrudingly on the guide bracket (400).

The guide projection (322) of the web portion (320) described above can be inserted into the guide groove (420) formed between the stoppers (410), and the guide projection (322) can be seated on the bottom surface of the guide groove (420). The stopper (410) can limit the relative movement distance of the relay bracket (300) in a direction perpendicular to the longitudinal direction of the long hole (321).

Fig. 12 is a drawing showing a three-dimensional frame structure and a basic frame structure of the present invention, and Fig. 13 is a drawing showing a disassembled state of the three-dimensional frame structure of Fig. 12.

Referring to FIGS. 12 and 13, the three-dimensional frame structure (500) is configured to allow the finishing panel (FP) to be arranged in a curved shape and can be fixedly connected to one side of the basic frame structure (200). One side of the basic frame structure (200) refers to the surface facing the finishing panel (FP).

The finishing panels (FP) may be formed in a curved shape or in a flat shape and arranged at an angle to each other to form an overall curved shape. In addition, a curved finishing panel (FP) and a flat finishing panel (FP) may be combined to form an overall curved shape.

The three-dimensional frame structure (500) may include a rear frame (510), a front frame (530), and a middle frame (540).

Figure 14 is a drawing illustrating area F of Figure 13.

Referring to FIGS. 13 and 14, the rear frame (510) is positioned adjacent to the basic frame structure (200) in a straight line, so that a straight line can be formed with one frame.

The rear frame (510) may include a basic flat plate portion (511), a side flat plate portion (512), and a wing portion (513).

The basic flat plate portion (511) is a basic portion formed in a flat plate shape with a predetermined length, the side flat plate portion (512) is a portion formed by extending from both sides of the basic flat plate portion (511), and the wing portion (513) is a portion formed by extending inwardly from one end of the side flat plate portion (512) of the basic flat plate portion (511).

The basic flat plate portion (511) of the rear frame (510) is different from the through hole (211a) of the basic flat plate portion (211) of the horizontal frame (210) described above in that it does not have the same configuration.

The side flat plate (512) of the rear frame (510) may have a dimple groove (512a) formed in a recessed manner, similar to the side flat plate (212) of the horizontal frame (210) described above.

The wing section (513) of the rear frame (510) may have a passage groove (513a) formed in the same manner as the wing section (213) of the horizontal frame (210) described above. One end of the intermediate frame (540) may be inserted into the passage groove (513a).

Referring to FIGS. 12 and 13, the front frame (530) enables the finishing panel (FP) to be arranged in a curved shape, and is spaced apart from the rear frame (510) and can be combined with the finishing panel (FP).

Figure 15 is a drawing showing a state in which the unit frames of Figure 13 are connected to each other.

Referring to Fig. 15, the front frame (530) may be formed by connecting a plurality of unit frames (520) having a predetermined length at an angle to each other. The width of one end of the unit frame (520) may be formed to be smaller than the width of the other end, so that one end of a unit frame (520) may be inserted into the other end of another adjacent unit frame (520), thereby connecting the plurality of unit frames (520) to each other.

Specifically, the unit frame (520) is a unit that constitutes the front frame (530), and forms a curved line overall as adjacent unit frames (520) are connected at an angle to each other, and may include a basic flat plate portion (521), a side flat plate portion (522), and a wing portion (523).

The basic flat plate portion (521) is a basic portion formed in a flat plate shape with a predetermined length, the side flat plate portion (522) is a portion formed by extending from both sides of the basic flat plate portion (521), and the wing portion (523) is a portion formed by extending inwardly from one end of the side flat plate portion (522) of the basic flat plate portion (521).

The basic flat plate portion (521) of the unit frame (520) is different from the above-described horizontal frame (210) in that it does not have the same configuration as the passage hole (211a) of the basic flat plate portion (211).

The side flat plate (522) of the unit frame (520) may have a dimple groove (522a) formed in a recessed manner, similar to the side flat plate (212) of the horizontal frame (210) described above. The dimple groove (522a) may be formed in multiple numbers at one end, the other end, and the intermediate portion between the one end and the other end of the side flat plate (522).

The wing section (523) of the unit frame (520) may have a passage groove (not shown in the drawing) formed in the same manner as the wing section (213) of the horizontal frame (210) described above. The other end of the intermediate frame (540) may be inserted into the passage groove.

Fig. 16 is a drawing showing a non-welding fastening means for fastening the front frame of Fig. 13.

Referring to FIG. 16, the non-welding fastening means (820) can penetrate the dimple grooves (212a, 222a, 512a, 542a) and simultaneously form screw threads on the inner surface of the dimple grooves (212a, 222a, 512a, 542a).

That is, the non-welding fastening means (820) can fasten the unit frame (520), the horizontal frame (210), the vertical frame (220), the rear frame (510), the front frame (530), and the intermediate frame (540) without a configuration such as a nut. For example, the non-welding fastening means (820) can be a self-tapping screw.

A non-welding fastening means (820) may be formed by a body (822) in which screw threads are formed, and a head (821) formed as an extension at one end of the body (822). The screw threads formed on the body (822) of the non-welding fastening means (820) rotate on the inner surface of the dimple grooves (212a, 222a, 512a, 542a) to form screw threads and may fasten other configurations.

For example, when a non-welding fastening means (820) penetrates a dimple groove (522a) formed at one end and the other end of a side flat portion (522) of a unit frame (520), the unit frames (520) can be connected to each other. When a non-welding fastening means (820) penetrates a dimple groove (522a) formed at a gap between one end and the other end of a side flat portion (522) of a unit frame (520), the intermediate frame (540) and the unit frame (520) can be connected.

In addition, in order to increase the fastening force, the threads of the non-welding fastening means (820) may be formed of a first thread portion (st1) and a second thread portion (st2). The pitch of the first thread portion (st1) may be formed smaller than the pitch of the second thread portion (st2). In addition, the pitch of the threads of the non-welding fastening means (820) may be formed in a form in which they gradually increase from one end of the body (822) to the other end.

The shape of these screw threads can allow the non-welding fastening means (820) to pass through one dimple groove (212a, 222a, 512a, 542a) and the other dimple groove (212a, 222a, 512a, 542a) so that the gap between the two dimple grooves (212a, 222a, 512a, 542a) becomes narrower.

Accordingly, for example, the side flat plate (522) of a unit frame (520) and the side flat plate (522) of another unit frame (520) can be tightly and firmly connected.

The non-welding fastening means (820) can be easily disassembled using a work tool. Accordingly, the basic frame structure (200) and the three-dimensional frame structure (500) can be easily disassembled into a vertical frame (220), a horizontal frame (210), a rear frame (510), a front frame (530), an intermediate frame (540), etc. The disassembled components can be reused for other purposes.

Fig. 17 is a drawing illustrating a modified embodiment of Fig. 15.

Referring to Fig. 17, the unit frames (520) of the front frame (530) can be connected to each other in another way. The unit frame (520) of Fig. 17 is connected in such a way that the side flat portion (522) does not belong to the same plane as the side flat portion (522) of another unit frame (520), and the finishing panel (FP) is arranged to face the side flat portion (522).

On the other hand, the unit frame (520) of FIG. 15 is connected in such a way that the basic flat panel (521) does not belong to the same plane as the basic flat panel (521) of another unit frame (520), and the finishing panel (FP) is arranged to face the basic flat panel (521).

Fig. 18 is a drawing showing the reinforcing plate of Fig. 13, and Fig. 19 is a drawing showing the state of fastening the horizontal frame and reinforcing plate of Fig. 18.

Referring to FIGS. 18 and 19, the reinforcing plate (830) reinforces the bonding force between the horizontal frame (210) and the vertical frame (220), and can be bonded to the connecting portion of the horizontal frame (210) and the vertical frame (220) in a clinching manner.

The clinching method is a fastening method in which different materials are placed in an overlapping manner, and then a large compressive force is applied using a compression member (P), so that the different materials are deformed by the compressive force and a catch (LP) is formed to interlock.

The reinforcing plate (830) can reinforce not only the connection between the horizontal frame (210) and the vertical frame (220), but also the connection between the rear frame (510), the front frame (530), the middle frame (540), the support frame (600), and the reinforcing frame (700) described above.

Referring to FIG. 14, the intermediate frame (540) connects the rear frame (510) and the front frame (530) to each other, and can be arranged in multiple numbers between the rear frame (510) and the front frame (530).

The middle frame (540) can be formed with a length corresponding to the distance between the rear frame (510) and the front frame (530).

A dimple groove (542a) may be formed at one end, the other end, and the middle of the middle frame (540).

One end of the intermediate frame (540) can be inserted into the passage groove (513a) of the rear frame (510) and then fastened by the non-welding fastening means (820) penetrating the dimple groove (512a, 542a), and the other end of the intermediate frame (540) can be inserted into the passage groove of the front frame (530) and then fastened by the non-welding fastening means (820) penetrating the dimple groove (522a, 542a).

Additionally, the intermediate frame (540) can be fastened to the reinforcing frame (700) by a non-welding fastening means (820) while in contact with the reinforcing frame (700) described later.

The middle frame (540) may include a base plate portion (541), a side plate portion (542), and a wing portion (543).

The basic flat plate portion (541) is a basic portion formed in a flat plate shape with a predetermined length, the side flat plate portion (542) is a portion formed by extending from both sides of the basic flat plate portion (541), and the wing portion (543) is a portion formed by extending inwardly from one end of the side flat plate portion (542) of the basic flat plate portion (5411).

The basic flat plate portion (541) of the intermediate frame (540) is different in that instead of having a configuration similar to the through hole (211a) of the basic flat plate portion (211) of the horizontal frame (210) described above, a dimple groove (541a) is formed.

The side flat plate (542) of the middle frame (540) may have a dimple groove (542a) formed in a recessed manner, similar to the side flat plate (212) of the horizontal frame (210) described above.

The wing section (543) of the intermediate frame (540) is different from the passage groove (213a) of the wing section (213) of the horizontal frame (210) described above in that it does not have the same configuration.

Referring to FIGS. 12 and 13, the support frame (600) connects and supports a pair of three-dimensional frame structures (500), and may be formed of a unit frame (610) having the same shape as the unit frame (520) described above. For example, the support frame (600) may have a rectangular shape with the unit frame (610).

The support frame (600) can be placed between one end and the other end of a pair of three-dimensional frame structures (500).

A pair of three-dimensional frame structures (500) and a pair of support frames (600) can be pre-assembled and combined. That is, a pair of three-dimensional frame structures (500) and a pair of support frames (600) form one assembly unit and can be fixedly combined to one side of a basic frame structure (200).

These assembly units are pre-assembled in a factory rather than on-site and transported to the site, where they can be directly fixed to the basic frame structure (200) on-site or fixedly connected with a fixing bracket (FB), etc. Since they can be pre-assembled as a single assembly unit and then installed on-site, the construction time of the finishing panel (FP) can be shortened.

Figure 20 is a drawing illustrating area G of Figure 13.

Referring to FIG. 20, the present invention may further include a reinforcing frame (700) that reinforces the bonding force between a pair of three-dimensional frame structures (500).

The reinforcing frame (700) can be formed in almost the same shape as the horizontal frame (210) described above. One end of the reinforcing frame (700) can be connected to a three-dimensional frame structure (500), and the other end can be connected to another three-dimensional frame structure (500).

A plurality of reinforcing frames (700) are installed between a pair of three-dimensional frame structures (500), thereby further increasing the bonding strength between the three-dimensional frame structures (500).

As described above, the present invention can be manufactured using a non-welding method, thereby preventing fire accidents and ensuring safe construction of finishing panels (FP). Furthermore, the present invention can be manufactured on-site using a non-welding method, thereby reducing the manufacturing time for the subframe and ensuring consistent joint strength between the frames forming the subframe. Furthermore, the present invention maintains a bond with the finishing panel (FP) without damage even when the ground shakes due to an earthquake, thereby preventing safety accidents caused by separation or falling of the finishing panel (FP). Furthermore, the present invention allows the finishing panel (FP) to be arranged in a curved shape, thereby flexibly adapting to various shapes of building exterior walls. Furthermore, the present invention can be manufactured using a non-welding method, thereby allowing it to be easily disassembled without damage, and the disassembled components can be recycled for other purposes. Furthermore, the present invention allows some components to be pre-assembled into a single assembly unit and then installed on-site, thereby reducing the construction time of the finishing panel (FP).
