Description

{Sway Brace Device For Buildings Like Pipe}

The present invention relates to an anti-shake brace for installing various types of pipes by hanging them on the ceiling or wall of a building structure and preventing excessive movement of the pipes in the event of an earthquake or external impact, and more specifically, to an anti-shake brace for more efficiently fixing and installing pipes in a narrow work space.

In general, pipelines are formed on the ceiling or walls of a building to allow fluids to flow, such as fire protection equipment or water pipes, or pipelines are hung to prevent electrical equipment from being exposed to the outside. However, if the pipelines shake during an earthquake or external impact, they may be broken or damaged, causing safety accidents such as water or electricity leaks. Therefore, anti-shake braces are used as a seismic design measure to prevent excessive movement. The seismic design of the above anti-shake braces is to make the structure and its related parts strong enough to withstand impacts so that they do not fall apart from each other, and in contrast, seismic isolation design uses buffers, etc. to separate the structure and its related parts from each other to block the effects of seismic waves.

The above anti-shake braces can be classified into longitudinal braces and transverse braces depending on the installation location, and can be classified into wall-fixed types and beam clamp types (BEAM CLAMP type) depending on the method of fixing them to the building structure, and can be classified into 30˚, 45˚, 60˚, and 90˚ depending on the installation angle.

Figures 1 and 2 illustrate examples of conventional anti-shake braces. Figure 1 is a side view illustrating a longitudinal brace in which a pipe connection device and a support member are installed on the same load application surface, and Figure 2 is a side view illustrating a longitudinal brace in which a pipe connection device and a support member are installed on different load application surfaces.

Referring to Fig. 1, an anchor bolt (3) is embedded in a concrete slab (1) of a ceiling, and a pipe (5) is fixed to the embedded anchor bolt (3) with an anti-shake support (10). The anti-shake support (10) is basically composed of a building attachment device (11), a support (12), and a pipe connection device (13). The building attachment device (11) is necessary for fixing to a building structure, and the pipe connection device (13) is necessary for directly fixing the pipe (5). In addition, separate adapters (14, 15) are used between the building attachment device (11) and the support (12), and between the support (12) and the pipe connection device (13) to enhance the strength against seismic force and as an auxiliary device for assisting construction. The conventional anti-shake brace (10) for earthquake-resistant design has many related parts and is heavy, so not only is the impact of the applied load large, but the installation work is also cumbersome and difficult, and the construction cost is high.

Meanwhile, the longitudinal brace is installed on the same load application surface in the load application direction (X-axis) to prevent movement in the direction parallel to the pipe axis (Y-axis direction) due to horizontal seismic load. However, it is not easy to embed an anchor bolt (3) and install a brace (10) vertically above an already installed pipe line. In particular, when the space between the ceiling (1) and the pipe line is narrow, it is practically difficult to install a brace (10) vertically above the pipe line.

Therefore, referring to Fig. 2, when the space between the ceiling (1) and the pipe (5) is narrow, an anchor bolt (3) is installed at a side position away from the load-acting surface of the pipe line, and the pipe (5) is fixed with an anti-shake brace (10) (hereinafter referred to as “side fixing” for convenience of explanation). In the illustrated example, a riser clamp is used as a pipe connection device (13), and the pipe (5) is fixed by fastening a bolt (13a) to each of the flanges (13b) protruding on both sides of the riser clamp, so that the anti-shake brace (10) is installed at a distance (L: see Fig. 1) between the pipe (5) and the bolt (13a). However, in this case, since the load-acting surface of the pipe (5) and the fixing point are different, the moment increases, which reduces the reliability of the installation state and parts.

The present invention has been devised to solve the above problems, and the purpose of the present invention is to provide an anti-shake support with a simplified structure that enables installation at a closer position vertically above a pipeline when the working space between a building structure and a pipeline is narrow, and to minimize the influence of a load transmitted from an external shock such as an earthquake.

In order to achieve the above-described object, the anti-shake brace according to the present invention is characterized by including: a building attachment device fixed to a building structure; a support member coupled and fixed to the building attachment device; a lower clamp having a first straight portion coupled to the support member, and a first arcuate portion extended from the first straight portion and formed in an arc shape so as to wrap and support an outer surface of a pipe; an upper clamp having a second straight portion, one side of which is movably inserted and fixed into the first straight portion of the lower clamp, and a second arcuate portion extended from the second straight portion and formed in an arc shape so as to wrap and support an outer surface of the pipe; and a tightening bolt for applying a tightening force to the pipe by pulling the second arc portion as the other side of the upper clamp so that a pressure is generated on the pipe in a state where the pipe is pushed between the first straight portion and the second straight portion between the upper clamp and the lower clamp.

The anti-shake brace according to the present invention has a reduced number of parts, a simple and lightweight structure, and reduced bolting work because there is no separate adapter between the building attachment device, the support, and the pipe connection device, and is therefore economical. In addition, since the installation position can be easily checked in a pre-assembled state, a separate tape measure, etc. is unnecessary, and since it is lightweight, work is easy in a narrow installation environment. In addition, the moment generated due to side fixing is minimized, so that installation and component reliability can be secured. In addition, as the tightening bolt is tightened, the pipe is pushed in between the first straight section and the second straight section, so that the wedge action enables use as a simple, earthquake-resistant pipe brace.

An anti-shake support according to an embodiment of the present invention will be described. An anti-shake support according to an embodiment of the present invention includes: a building attachment device fixed to a building structure; a support member coupled and fixed to the building attachment device; a lower clamp having a first straight portion coupled to the support member, and a first arcuate portion extended from the first straight portion and formed in an arc shape so as to surround and support an outer surface of a pipe; an upper clamp having a second straight portion, one side of which is movably inserted and fixed into the first straight portion of the lower clamp, and a second arcuate portion extended from the second straight portion and formed in an arc shape so as to surround and support an outer surface of the pipe; and a tightening bolt that applies a tightening force to the other side of the upper clamp by pulling the second arcuate portion so that a pressure is generated on the pipe while the pipe is pushed between the first straight portion and the second straight portion between the upper clamp and the lower clamp. The lower clamp has a first flange having a shape that is bent outwardly from the first circular portion; the upper clamp has a second flange having a shape that is bent outwardly from the second circular portion to face the first flange; and the first flange and the second flange are fixed by the tightening bolt. It is preferable that the second circular portion has an arc length smaller than that of the first circular portion. A slot is formed in the first straight portion; and it is preferable that the second straight portion is fixed to the first straight portion by being movably inserted into the slot forward-backward or up-down. The building attachment device has a flat-plate building attachment portion that is fixed to a building structure, and a flat-plate support attachment portion having a shape that is bent from the building attachment portion; and it is preferable that the support is fastened to the support attachment portion and the first straight portion with a bolt so that the installation angle between the building attachment device and the lower clamp can be changed. It is preferable that the above first straight line portion is connected longitudinally parallel to the support.

Hereinafter, with reference to the attached drawings, an anti-shake brace as a preferred embodiment of the present invention will be described in more detail.

FIG. 3 is a perspective view illustrating an isolated view of an anti-shake brace as a preferred embodiment according to the present invention, FIG. 4 is a perspective view illustrating an assembled view of the anti-shake brace of FIG. 3, and FIG. 5 is a longitudinal side view of the anti-shake brace of FIG. 3.

Referring to FIGS. 3 to 5, a preferred embodiment of an anti-shake support (T) according to the present invention includes a building attachment device (100), a support (200), and a pipe connection device (300).

The above-described building attachment device (100) is, as an example, composed of a roughly rectangular flat plate divided into two parts, a building joint part (110) and a support joint part (120). Bolt holes (111, 121) are formed in the building joint part (110) and the support joint part (120) so that bolts can be received, respectively, and the support joint part (120) is bent to form approximately 90˚ from the building joint part (110). Accordingly, the building joint part (110) is firmly fixed by being fastened to an anchor bolt embedded in a concrete slab with a nut, for example, and the support joint part (120) is fixed to the support (200) with, for example, a bolt (100a) and a nut (100b). Here, the building attachment device (100) is described as an example of a device that is fixed to a slab of a building structure, or a flat-plate bending shape, or a fastening method using bolts and nuts, but various structures or devices known in the field to which the present invention pertains can be used, and it can also be fixed to a steel structure of a building, or fixed by auxiliary use of a separate part, or simply by forming a screw thread without a nut. Since this is obvious to those skilled in the art, a detailed description thereof is omitted for convenience of explanation.

The above support (200) is formed as an example of a roughly rectangular flat plate, and has bolt holes (210, 220) formed at the upper and lower portions, so that the upper portion is connected to a building attachment device (100) and the lower portion is connected to a pipe connection device (300) using bolts (100a, 200a) and nuts (100b, 200b). The illustrated example shows the 0˚ position for convenience of explanation, but the installation angle can be changed to 30˚, 45˚, 60˚, or 90˚, etc. depending on the installation environment of the pipe line (see FIG. 4). In this case, the bolts (100a, 200a) and nuts (100b, 200b) are released, and the angle of the support (200) is adjusted according to the installation angle, and the bolts (100a, 200a) and nuts (100b, 200b) are fastened to secure it. In addition, it is preferable that the support (200) be formed so that the lower end thereof is rounded with a radius (r) that is the distance from the cross-sectional extension (321a) of the second straight portion (321) of the upper clamp (320) to the center of the bolt hole (220), so that the distance from the cross-sectional extension (321a) of the second straight portion (321) can be minimized while the installation angle can be freely changed. Here, the support (200) is preferably a flat plate to reduce weight and facilitate installation, but a support (200) such as an "H" or "I" shaped steel may be used, and also, without a nut (100b, 200b), a screw thread may be simply formed and fastened with a bolt (100a, 200a) to fix it. Since this is obvious to those skilled in the art, a detailed description thereof will be omitted for convenience of explanation.

The above pipe connection device (300) includes a lower clamp (310) that supports a pipe (P: see FIG. 6) by being combined with a support (200), an upper clamp (320) that is movably inserted and fixed in the lower clamp (310), and a tightening bolt (330) that applies a tightening force by pulling one side of the upper clamp (320) so that a pressure is generated on the pipe (P) between the upper clamp (320) and the lower clamp (310).

For convenience of explanation, the lower clamp (310) is provided with, for example, a first straight section (311), a first arc section (312), and a first flange (313). Here, the lower clamp (310) may be manufactured as separate parts and then joined together as a single piece, but for processing, forming, or mechanical properties, it is preferable to manufacture it by forming a flat plate as a single piece as in the illustrated example.

The first straight section (311) above has, as an example, a bolt hole (314) formed at the upper end, and is coupled with the support (200) in a state where they are in contact with each other using a bolt (200a) and a nut (200b) through the bolt hole (314), and a rectangular slot (311a) is formed at the lower side of the bolt hole (314), and a cross-sectional extension (321a) of the upper clamp (320) is received and caught in the slot (311a), so that one end of the lower clamp (310) is coupled with the upper clamp (320). The above slot (311a) is vertically rectangular, and since the second straight line portion (321) of a long shape described later moves back and forth and up and down, the upper clamp (320) and the lower clamp (310) can be separated from each other, so there is an advantage in that it is easy to attach and detach from the pipe (P). (See FIG. 6) Here, the bolt hole (314) is used to mean a through hole in which a bolt (200a) is received, but it can also be fixed without a nut (200b) by forming a screw thread and directly connecting it to the bolt (200a) as a screw hole, and also, although a rectangular slot (311a) is illustrated, if the second straight line portion (321) can move, its shape can be changed in various ways. In addition, the slot (311a) may be formed by extending to the first circular portion (312), but since the supporting force of the pipe (P: see FIG. 6) of the first circular portion (312) may decrease, it is preferable not to form it in the first circular portion (312) that comes into contact with the pipe (P). In addition, as shown in FIG. 5, the first straight portion (311) is fixed in a state where it is in contact with the support (200), but it is obvious to those skilled in the art that various changes can be made, such as changing the position or changing the shape, as long as it is substantially coupled in a parallel longitudinal direction (Y-axis direction), and therefore, a detailed description thereof will be omitted.

The above first circular portion (312) is formed by extending from the first straight portion (311), for example, and is formed in an arc shape so as to surround and support the lower outer surface of the pipe (P). In addition, the first flange (313) is formed by bending outward from the first circular portion (312), and has a bolt hole (315) formed therein to be mutually connected with the second flange (323) described later.

The upper clamp (320) is, as an example, manufactured by integrally molding a flat plate, and for convenience of explanation, it is divided into a second straight section (321), a second arc section (322), and a second flange (323).

The above second straight line portion (321) has, as an example, a roughly “T” shape, and has a shape in which a cross-sectional expansion portion (321a) having a relatively expanded cross-section and a cross-sectional reduction portion (321b) having a relatively reduced cross-section compared to the cross-sectional expansion portion (321a) are integrally formed. In addition, it is preferable that the second straight portion (321) has a shape that is bent toward the first circular portion (312) so that the wedge action can be increased. To this end, the tangent line of the second circular portion (322) is inclined on a line orthogonal to the first straight portion (311), and in the illustrated example, the angle of inclination (α) is 10°. (See FIG. 5) As another example, if a slot (311a) is formed slightly below the top of an imaginary circle (a circle formed by a broken line in FIG. 5) that overlaps the arc of the first circular portion (312), the first straight portion (311) may have a shape that is bent toward the first circular portion (312) due to a state of tension caused by the tightening of the tightening bolt (330).

The above-mentioned cross-sectional extension part (321a) has, for example, a width greater than the width of the slot (311a) and a width smaller than the vertical length of the slot (311a). The above-mentioned cross-sectional extension part (321a) is inserted into the rectangular slot (311a) and turned so as to be fixed by being caught on the first straight part (311). Once caught and fixed, it is useful because it does not easily come off the slot (311a) during movement, work, or when the installation angle is to be changed. Here, the above-mentioned cross-sectional extension part (321a) and the slot (311a) can be variously changed in various ways known in the art. As an example, when using an "ㅗ" shaped slot (311a), the cross-sectional extension part (321a) can be inserted directly from the lower side and raised so as to be fixed by being caught on the first straight part (311). However, in this case, the upper clamp (320) may fall off unintentionally due to its own weight while moving or working, which may be inconvenient, especially when working in a narrow space. Therefore, it is preferable to use a straight longitudinal slot (311a).

FIG. 6 is a side view of a pipe connection device of an anti-shake brace according to an embodiment of the present invention.

Referring to FIGS. 4 to 6, the cross-sectional reduction portion (321b) has, as an example, a width smaller than the width of the slot (311a), and is preferably elongated to a length approximately equal to the radius of an imaginary circle corresponding to the arc shape of the first circular portion (312). Here, the cross-sectional reduction portion (321b) moves forward and backward or up and down in the slot (311a) to open between the first circular portion (312) so that the pipe (P) can be inserted and removed, and the pipe (P) can be easily removed, thereby increasing the convenience of work, which is advantageous. In addition, the illustrated example is an example that can open between the slot (311a) by having an elongated shape, and can be changed to various shapes and its thickness and length can be appropriately adjusted depending on the environment, and since this is obvious to those skilled in the art, a detailed description thereof will be omitted.

The second circular portion (322) is, as an example, a shape in which the cross-section is expanded to a width greater than the width of the reduced cross-section in order to increase rigidity and increase the contact area with the pipe (P), and is formed in an arc shape so as to be able to wrap and support the outer surface of the pipe (P), and has substantially the same curvature as the first circular portion (312) and functions to pressurize the pipe (P) together with the first circular portion (312). Here, the first circular portion (312) is configured to support the pipe (P) from below, and the second circular portion (322) forms a structure in which, together with the second straight portion (321), the pipe (P) is pressed from above, so that the second circular portion (322) has an arc length smaller than that of the first circular portion (312). In addition, in order to force the pipe (P) between the second straight section (321) and the first straight section (311) and secure it strongly by a wedge action, the arc length of the first circular section (312) is smaller than 1/2 of the pipe (P), and the arc length of the second circular section (322) is smaller than 1/4 of the pipe (P).

The second flange (323) is formed by bending outwardly from the second circular portion (322), as an example, and is fixed with a tightening bolt (330) through the through hole while being positioned so as to face the first flange (313) of the lower clamp (310) by forming a bolt hole. Here, the tightening bolt (330) may be inserted into the bolt holes of the first flange (313) and the second flange (323) and fastened with a nut (340) to fix the flange. However, it is advantageous to more effectively transmit the tightening force and generate the pressing force more evenly by using a screw hole (324) with threads formed in the bolt hole of the second flange (323) and fastening the tightening bolt (330) into the screw hole (324) without using a nut (340).

Figure 7 illustrates a state of tightening bolt fastening. Figure 7a illustrates a side view of a tightening bolt with a nut, and Figure 7b illustrates a side view of a tightening bolt that is coupled to a screw hole without a nut. Here, for convenience of explanation, the state before pressurizing the pipe (P) is illustrated with a broken line, and the state after pressurizing the pipe (P) is illustrated in real life.

Referring to Fig. 7a, when the pipe (P) is positioned between the lower clamp (310) and the upper clamp (320), the tightening bolt (330) is inserted into the bolt holes (315, 325) of the first flange (313) and the second flange (323) and is filled and fixed with a nut (340), the first flange (313) and the second flange (323) correspond to free ends, and since there is a gap between the bolt holes (315, 325) and the tightening bolt (330), even if the tightening force of the tightening bolt (330) is increased, rather than transmitting the tightening force, the first flange (313) and the second flange (323) sag due to the bending force, so that the flange and the tightening bolt (330) are misaligned, deforming or twisting each other, and effectively affecting the upper clamp (320). Since the clamping force cannot be transmitted, it is impossible to expect uniform pressing force or effective tight fixation depending on the deformation.

Meanwhile, referring to Fig. 7b, when a tightening bolt (330) is inserted into a bolt hole (315) of a first flange (313) and is directly screwed into a screw hole (324) of a second flange (323) while a pipe (P) is positioned between a lower clamp (310) and an upper clamp (320), the first flange (313) of the lower clamp (310) corresponds to a free end and a gap exists, so some sagging occurs due to the bending force and deformation occurs. However, since the second flange (323) of the upper clamp (320) is screw-connected with the tightening bolt (330), the gap can be practically ignored, and furthermore, even at the free end, the distance between the bolt head and the screw thread is maintained constant, so that the second flange (323) of the upper clamp (320) continues to tension the second straight portion (321) or pull the second arc portion (322) until it yields to pressurize the pipe (P). Accordingly, the tightening bolt (330) can more effectively transmit the tightening force to the upper clamp (320), and since the second flange (323) can be reduced from being bent and deformed, a more uniform pressing force and effective close fixing can be expected for the upper clamp (320).

As one example of the anti-shake support (T) according to the present invention, the installation process will be examined.

Referring to FIGS. 3 and 4, the support (200) and the building attachment device (100) are fixed with bolts (100a) and nuts (100b) to an installation angle suitable for the work environment, thereby preparing for work. Next, the cross-sectional expansion part (321a) of the upper clamp (320) is vertically inserted into the slot (311a) of the lower clamp (310) and turned so that the upper clamp (320) is caught on the lower clamp (310).

Next, the cross-sectional reduction portion (321b) is pushed forward into the slot (311a) and lifted upward to separate the upper clamp (320) from the lower clamp (310). (See Fig. 6) At this time, since the second arc portion (322) is smaller than the arc of the first arc portion (312) and the second straight portion (321) is formed long, the pipe (P) can be inserted into the lower clamp (310) in the "A" direction. (See Fig. 6) Next, the pipe (P) is placed in the first arc portion (312) of the lower clamp (310). (See Fig. 6)

Next, the building attachment device (100) and the support (200) are connected, and then the anchor bolt embedding position is confirmed and marked by placing it between the building structure such as the ceiling or steel beam and the lower clamp (310), and the anchor bolt embedding work is performed. Next, the building attachment device (100) is fitted onto the anchor bolt and fixed by fastening it with a nut, and the support (200) and the bolt holes (220, 314) of the lower clamp (310) are aligned with each other and fixed by fastening them with the bolt (200a) and the nut (200b). Finally, the tightening bolt (330) is screwed into the screw hole (324) of the second flange (323) of the upper clamp (320) through the bolt hole (315) of the first flange (313) of the lower clamp (310) and tightened firmly to complete the installation.

As described above, the anti-shake brace (T) according to the present invention has a reduced number of parts, a simple and lightweight structure, and reduced bolting work because a separate adapter is not required between the building attachment device (100) and the support (200), and between the support (200) and the pipe connection device (300), and is therefore economical. In addition, since the lower clamp (310) is positioned on the already installed pipe line and the support (200) and the building attachment device (100) are temporarily assembled, the installation location can be easily confirmed, so a separate tape measure, etc. is not necessary, and since it is lightweight, work is easy in a narrow installation environment.

Meanwhile, when installing an anti-shake brace (T) in a narrow space, side fixing of the pipe (P) cannot be helped, and at this time, in order to reduce the moment due to the side fixing, it is necessary to minimize the distance from the fixing point (e.g., anchor bolt embedding position) to the pipe (P). In the case of the anti-shake brace (T) according to the present invention, the fixing point can be positioned at a location in contact with the pipe (P), so the distance to the pipe (P) is reduced, thereby reducing the operating moment, thereby ensuring the installation state and component reliability.

Fig. 8 illustrates the simulation results of an anti-shake brace as an example according to the present invention. Here, the simulation was conducted using the Catia V5 program of Dassault Systems under the condition that the M12 bolt was fastened at 80N.

Referring to FIGS. 5, 7 and 8, in the anti-shake brace (T) according to the present invention, as the tightening bolt (330) is tightened, a wedge action occurs between the first straight portion (311) and the second straight portion (321), and the first arc portion (312) and the second arc portion (322) pressurize and close the pipe (P), and further, by continuously pulling the tightening bolt (330) until it screw-connects with the second flange (323) of the upper clamp (320) and yields, the pipe (P) is more firmly and closely fixed between the first straight portion (311) and the second straight portion (321) and the first arc portion (312) and the second arc portion (322), so that it can be used as an earthquake-resistant anti-shake brace (T) despite its simple structure.

As described above, the anti-shake brace according to the present invention is more specifically illustrated and described with an embodiment as a specific content for carrying out the invention, but is not limited thereto, and rather should be understood to include all modifications, equivalents, or substitutes thereof within the technical idea and scope defined by the appended claims.
