Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry construction method for assembling light-weight cellular concrete (hereinafter abbreviated as ALC) wall panels in a vertically stacked connection state, and an improvement in a joint used therefor.

[0002]

2. Description of the Related Art This type of assembly method for ALC wall panels (commonly referred to as vertical stacking method) and joints therefor have already been disclosed in JP-A-62-236938 and JP-A-1-97741.
No. 1, No. 1-97742, No. 1-121440, No. 1
-154934, 1-158144, 1-15
8145, 1-147748, 1-29084.
No. 3 and No. 2-13636 are proposed.

Both of them are dry methods which do not use mortar, and when the steel frame body of a building is deformed by an earthquake or the like, each of the wall panels is so-called locking, so that the steel frame body reasonably follows the steel frame body. It is said that the wall panel and its joints do not exert a large force, and it has the advantage of being able to construct an outer wall with high seismic isolation.

[0004]

However, in any of the above-mentioned known inventions, as a locking mechanism for obtaining the seismic isolation, the types and points of the necessary parts and the assembly required for each wall panel are still required. Since the number of processes is very large and the workability at the construction site is poor, it is easy for the contractor to actually avoid it.

Further, it is necessary to preliminarily bury steel rods, bolts, nuts, anchors and other anchor metal fittings at predetermined positions accurately at two upper and lower positions of each wall panel. Since it is a special product from the point of view, there is no restriction on the molding of the wall panel, it cannot be performed at low cost, and the mass production effect is poor.

That is, the same as Japanese Patent Laid-Open No. 1-158145.
Speaking of a typical example of No. -13636, in the former case, at the construction site, the long hole (1f) and the counterbore hole (1e) are perforated at the upper and lower portions of the wall panel (1) in a communicating state. , The locking rod (2) must be passed through the fitting (O bolt) (3) inserted from the counterbore (1e).

Further, the supporting members (4), (5) and (8) themselves which are fitted into the mounting metal fitting (3) from the inside of the room also have the upper and lower parts thereof.
It is a part that changes differently at the point, and after the fitting, the nuts (9) and (9) must be fastened,
It is extremely complicated in the work of assembling the wall panels (1) one by one with respect to the structural frame (beam) (7).

On the other hand, in the latter case, each wall panel (27) (2)
8) Two upper and lower parts of the embedded hardware with pre-threaded holes (3
2) needs to be buried, and the embedded hardware (32)
At the construction site, the mounting bolts (31) and (36) must be inserted and fastened, respectively. It is very difficult to screw and fasten it accurately.

Further, a pair of upper and lower mounting bolts (31)
(36) T type mounting hardware (2
6) and the lightning type metal fitting (34) are also different parts from each other, and a receiving plate (37) of a part different from these parts is also required.

[0010]

[0013]

The first aspect of the present invention relates to an assembling method at the top of a general beam,
According to the above-mentioned configuration, the lower half plate piece of the connecting metal fitting is dropped into the slit of the mounting metal fitting for beam which is fixedly installed in advance at the ruler angle of the beam from the upper side so as to be immersed, and the mounting metal fitting From the horizontal plate piece to the upper half plate piece of the connecting fitting that is exposed upward, the arc concave groove opened in the center of the lower end of the wall panel is also dropped from the top and locked, and the lower end of the wall panel After the part is kept in a fixed state, the remaining upper end is pushed inward toward the room so as to contact the ruler angle.

Then, the arc concave groove formed by cutting out at the center of the upper end of the wall panel is a slit of another mounting bracket for beam which is fixedly installed in advance at the upper ruler angle.
Since it will automatically match each other's communication state, the lower half plate piece of another connecting metal fitting is also dropped from the above into the arc concave groove opening to the center of the upper end through the slit and locked. Then, the upper end of the wall panel is also kept in a fixed state, and by repeating such an assembling operation, a plurality of wall panels can be sequentially stacked vertically from the lower stage to the upper stage.

The second aspect of the invention also includes a method of assembling the foundation portion. According to the above construction, a vertical plate piece is attached from the mounting angle for the foundation which is fixedly fixed to the ruler angle of the foundation. Since it is erected in an upright manner, the lower edge of the wall panel is locked by dropping the circular arc concave groove opened at the center of the lower end of the wall panel into the vertical plate piece from above and locking it. The parts can be lightly and stably assembled and fixed even on a concrete foundation, and can be sequentially vertically stacked and connected from the lowermost stage to the upper stage by the assembling method of the first invention.

Further, a third aspect of the present invention relates to a joint used for implementing the first and second aspects of the present invention, and according to the above configuration, a beam mounting bracket for receiving the weight of the wall panel and an orthogonal state from above the beam mounting bracket. Because it consists of a male and female pair with a connecting fitting that can be freely inserted and removed, if you simply drop it in,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings. FIGS. 1 to 6 show an assembled state of an ALC wall panel at the top of a general beam of a building, and (11) shows a beam made of an I-shaped steel material. , (12) is a ruler angle fixed to the upper end of the ruler by welding, and (P) is an ALC wall panel having a constant width (w), length (d) and thickness (t), Reinforcing reinforcing bars (13) are embedded in the interior in a vertically and horizontally intersecting state.

A pair of arcuate concave grooves (14) and (15) are cut out at the center of the upper end and the center of the lower end of the wall panel (P) at a molding factory or a construction site. . (O-O) and (H-H) are virtual vertical center lines that divide the width (w) and the thickness (t) of the wall panel (P) into two equal parts, and both vertical center lines (O-O) ( A pair of arcuate concave grooves (14) and (15) are located on the opening (H-H).

(J) is a general term for joints in which a pair of adjacent upper and lower wall panels (P) are assembled in a vertically stacked connection state by using the ruler angle (12) of the beam (11). Wall panel (P) so that it can be expanded to 7 to 15
A pair of male and female of a beam mounting metal fitting (A) for receiving its own weight and a connecting metal fitting (B) which is vertically inserted into the beam mounting metal fitting (A) and is freely inserted and removed.

That is, the mounting bracket (A) is first bent from a single metal plate into a substantially L-shape in a side view, and its vertical plate piece (16) is a ruler angle () of the beam (11). As a mounting base for 12), it will be welded and fixed to the vertical surface of the ruler angle (12). Then, in the fixed state, as is clear from FIGS. 1 to 5, the remaining horizontal plate pieces (1
7) protrudes from the ruler angle (12) in the outdoor direction.

However, as far as it can be attached and used as described above, instead of bending the attachment metal fitting (A) into a substantially L-shape in side view as shown in FIGS. 9 and 10, various modifications shown in FIGS. As shown in the example, while shaping it into a sideways T-shape in side view or bending it into an almost L-shape, fold the upper end of the vertical plate piece (16) back into a hook shape and move it to the ruler angle (12). It does not matter even if it is shaped so that it can be locked from above.

The horizontal plate piece (17) of the fitting (A) is larger than the vertical plate piece (16) so as to stably receive the upper wall panel (P), and the connecting metal fitting is dropped into this. An elongated slit (18) for use in the opening is formed. As shown in FIG. 5, the slits (18) extend in parallel for a certain length (s) along the longitudinal direction of the ruler angle (12), and the thickness of the wall panel (P). There is an opening on the virtual vertical center line (H-H) that divides (t) into two equal parts.

Next, the connecting fitting (B) is also punched from a single metal plate into a generally T-shape as viewed from the front.
The fixed width (w1) of the lower half plate piece (19) is made slightly smaller than the opening length (s) of the slit (18), so that the slit (1) of the mounting bracket (A) is
8) can be passed. Moreover, the left and right edges of the lower half plate piece (19) defining the constant width (w1) are notched, so to speak, as vertical straight surfaces (y1) parallel to each other. Similarly, the lower edge of the lower half plate piece (19) is shaped into a circular arc convex curved surface (x1).

On the other hand, the upper half plate piece (20) of the connecting fitting (B)
Is a fixed width (w2) larger than the opening length (s) of the slit (18), and preferably the same width dimension as the horizontal plate piece (17) of the mounting bracket (A). , The upper half-plate piece (2 that defines its constant width (w2)
The left and right edges of 0) are also cut off, so to speak, as vertical straight surfaces (y2) parallel to each other.
Further, the upper edge of the upper half plate piece (20) is also shaped into an arc convex curved surface (x2).

That is, based on the difference in width (z) between the constant width (w2) of the upper half plate piece (20) and the above constant width (w1) of the lower half plate piece (19) in the connecting fitting (B). The pair of left and right ear pieces (20a) protruding relatively laterally from the upper half plate piece (20) engage with the horizontal plate piece (17) of the mounting bracket (A) from above. That is, the connecting fitting (B) is hung. Therefore, as long as this effect can be achieved, as shown in the modification of FIG. 15, the upper half plate piece (20) and the lower half plate piece (19) of the connecting fitting (B) are made to have the above-mentioned constant width (w1). ) (W2) that varies in width may be stamped and formed in a half-moon shape in front view.

However, as described above with reference to FIGS. 7, 8 and 13, 14, the upper half plate piece (20) in the connecting fitting (B).
If the left and right edges of the lower half plate piece (19) are shaped as vertical straight surfaces (y1) (y2) that are parallel to each other, both plate pieces (19) (20) will be wall panels as described later. (P) The circular arc concave curved grooves (14) and (15) in the use state respectively locked with the circular arc concave curved grooves (14) and (15)
And between the straight surfaces (y1) and (y2),
As suggested from FIG. 6, an inevitable constant void (g1)
(G2) is generated, and as a result, the behavior of the wall panel (P) is given flexibility in terms of seismic isolation, and the assembling work for locking is facilitated.

Further, when the lower half plate piece (20) of the connecting metal fitting (B) is dropped into the slit (18) of the mounting metal fitting (A), the horizontal plate piece (17) of the mounting metal fitting (A) is used. In other words, as a partition boundary line (XX), the upper half plate piece (20) and the lower half plate piece (19) of the connecting fitting (B) have the same amount (h).
1) It is preferable to dimension so that only (h2) protrudes in the reciprocal direction. Furthermore, the upper half plate (2
It is desirable that the radius of curvature of the arc convex curved surfaces (x1) and (x2) given to the upper edge of (0) and the lower edge of the lower half plate (19) are set to have the same radius of curvature.

In doing so, it is necessary to distinguish a pair of the arc concave grooves (14) and (15) from each other when the notches are formed in the center of the upper end and the center of the lower end of the wall panel (P). In addition to being able to perform high-efficiency cutting using a common circular saw without any restrictions, the wall panel (P) can be cut by the centering action of the circular arc convex curved surfaces (x1) and (x2) in the connecting fitting (B). The virtual vertical center line (O-O) (H-
H) has the advantage that it can be correctly placed on its own under easy assembly work.

Next, FIGS. 16 and 17 show an assembled state of the wall panel (P) at the foundation of the building, (21)
Is a concrete foundation, (22) is a reinforcing bar embedded in the inside, and (23) is a base integrally attached to the upper end of the foundation (21) under welding and fixing with the reinforcing bar (22). A base ruler angle (24), which is an angle and is parallel to the ruler angle (12) of the beam (11), is fixed and laid by welding from above.

Further, (C) is a base mounting metal fitting for assembling the wall panel (P) to the ruler angle (24), and as shown in FIG. 18, it is also fixed width from one metal plate. (W3) is provided with a vertical plate piece (25) and a horizontal plate piece (26) and is bent into a substantially L shape in a side view, and
The protruding end of the horizontal plate piece (26) has a vertical plate piece (2
5) It is finished as a so-called hollow box type mounting base having high rigidity with respect to the ruler angle (24) of the foundation (21) by being further folded back so as to come into contact with the mid-height position. Then, the mounting base is welded and fixed to the horizontal surface of the ruler angle (24) from above.

In this case, the vertical plate piece (25) of the base mounting bracket (C) is the upper half plate piece (2) of the above-mentioned connecting bracket (B).
0), its upper edge is an arc convex curved surface (x
3), and the right and left edges are formed as vertical straight surfaces (y3) parallel to each other.

Further, the radius of curvature of the circular arc convex curved surface (x3) is determined to be the same as that of the circular arc convex curved surface (x2) of the upper half plate piece (20) of the connecting fitting (B). Regarding the amount (h3) of the vertical plate piece (25) of the mounting bracket (C) protruding from the upper surface of the hollow box type horizontal plate piece (26), the upper half plate piece (20) of the connecting bracket (B) is also stretched. It is dimensioned to be the same as the given amount (h2). still,
The fixed width (w3) of the mounting bracket (C) is also set to the same size as the fixed width (w2) of the upper half plate piece (20) in the connecting bracket (B).

When assembling the wall panels (P) in the vertically stacked connection state using the joint (J) as described above, the base ruler angle (24) and the beam ruler angle that are parallel to each other are installed. The horizontal plate piece (26) of the base mounting bracket (C) and the vertical plate piece (16) of the beam mounting bracket (A) are welded and fixed to the predetermined position of (12), respectively. On the other hand, a pair of circular arc concave grooves (14) and (15) are cut out at the upper end center and the lower end center of the wall panel (P) by using a circular saw at the construction site. The assembly work is done as follows. In addition, both arc concave groove (1
4) As described above, (15) may be preliminarily opened in the wall panel (P) molding factory.

That is, an arcuate concave groove (15) which is opened at the center of the lower end of the lower wall panel (P) is first extended to the vertical plate piece (25) protruding from the mounting bracket (C) for foundation to the vertical plate piece (25) shown in FIG.
As shown in FIG. 6, the upper end portion of the lower wall panel (P) is dropped from above and locked, and the upper end of the lower wall panel (P) is angled with a ruler (1) of the beam (11).
Push it toward the room so that it touches 2).

By doing so, the circular arc concave groove (14) opening in the center of the upper end of the lower wall panel (P) and the slit (1) opening in the horizontal plate piece (17) of the beam mounting bracket (A).
And 8) will be in self-conformity with each other on the virtual vertical center line (O-O) (H-H).

Therefore, the upper wall of the lower wall panel (P) is inserted into the circular arc concave groove (14) opened at the center of the upper end of the lower wall panel (P) through the slit (18) of the beam mounting bracket (A), and is added to FIG. 1 from above. , The lower half plate piece (1) of the fitting (B)
The lower wall panel (P) is primarily maintained in a fixed state by dropping and immersing 9), and the connecting metal fitting (B) and the mounting metal fitting (A) are temporarily fixed by spot welding or the like. The spot welding can be effectively applied to the protruding ear portion (20a) of the connecting fitting (B).

In the fixed state, the connecting metal fitting (B) and the horizontal plate piece (17) of the beam mounting metal fitting (A) make the virtual vertical center line (O-O) (H-H) of the wall panel (P). ), They are orthogonal to each other correctly, and the wide upper half plate piece (20) of the connecting metal fitting (B) also rises a certain amount (h2) upward from the horizontal plate piece (17) of the mounting metal fitting (A). ) Only exposed.

Then, the lower wall panel (P) is dropped into the upper half plate piece (20) of the exposed connecting metal fitting (B) with respect to the vertical plate piece (25) of the base mounting metal fitting (C). Similarly, as shown in FIGS. 1 and 2, the arcuate concave groove (15) that opens in the center of the lower end of the upper wall panel (P) is dropped from above and locked, and the upper wall panel (P) is also locked. ) Is pushed toward the inside of the room. Then, the pair of upper and lower adjacent wall panels (P) are joints (J).
The result is a stable vertical stacking state as shown in FIGS. Then, by repeating such an operation, the plurality of wall panels (P) are sequentially stacked vertically from the lower stage to the upper stage.

As described above, the arcuate concave grooves (14) (15) opening at the upper end center and the lower end center of the wall panel (P).
However, the corresponding arc convex curved surface (x1) (x2) (x
3) The upper half plate piece (20) and the lower half plate piece (19) of the connecting metal fitting (B) provided with 3) and the vertical plate piece (25) of the base mounting metal fitting (C) are locked. Therefore, the above-mentioned dropping operation of the wall panel (P) can be performed extremely easily and efficiently, and as long as it is dropped as described above,
This will be completed as the work of assembling the wall panel (P).

Further, the vertical plate piece (25) of the base mounting bracket (C) or the connecting bracket (B) dropped so as to be orthogonal to the slit (18) of the beam mounting bracket (A) is any one of them. Also, the virtual vertical center line (O-O) (H) of the wall panel (P)
-H), the circular arc convex curved surface (x1) (x2) (x3) and the circular arc concave curved groove (14) (1) are correctly positioned.
5), the wall panel (P) is held in a locked state with the wall panel (P), so that the wall panel (P) performs a smooth rolling action, and the beam (11) and the foundation (21) are subjected to an earthquake or the like. ), Etc., even if the structural frame undergoes interlayer deformation,
The behavior that follows this can be performed without any hindrance, and excellent seismic isolation can be exhibited.

As is clear from FIG. 5, the adjacent left and right sides of the wall panel (P) are kept in a so-called concave-convex fitting state, and the adjacent upper and lower sides of the wall panel (P). Similarly, each wall panel (P) is not fixed by cement mortar and is in a state in which it can act as a rocking when it encounters an earthquake or the like.

[0043]

As described above, according to the present invention, as a method of assembling the ALC wall panel (P), the ruler angle (12) fixedly mounted on the beam (11) is used to make a pair of adjacent upper and lower parts. When assembling the ALC wall panel (P), an arc concave groove (1) is formed at the center of the upper end and the center of the lower end of each wall panel (P).
4) The circular plate groove (14) (1) is formed on the horizontal plate piece (17) protruding from the beam mounting bracket (A) fixed to the ruler angle (12) while opening the notch (15).
5) A slit (18) which can communicate with 5) is formed in an opening, and through the slit (18) of the mounting bracket (A), a circular arc concave groove (1) opened at the center of the upper end of the lower wall panel (P).
4) Inside, the narrow lower half plate piece (19) of the connecting metal fitting (B) which is almost T-shaped in front view is orthogonal to the horizontal plate piece (17) of the mounting metal fitting (A) from above. To the wide upper half plate piece (20) of the connecting metal fitting (B) which is exposed from the horizontal plate piece (17) of the mounting metal fitting (A), and then to the upper wall panel ( Since the arcuate concave groove (15) that opens at the center of the lower end of P) is also dropped and locked from above, it has the effect of completely solving the problems of the prior art mentioned at the beginning. .

That is, it suffices to prepare a joint (J) consisting of a male and female pair of a mounting bracket (A) for a beam and a connecting bracket (B), and the wall panel (P) at the top of a general beam can be controlled by the minimum number of parts. The assembling work can be performed remarkably lightly and efficiently under the same operating method. Especially, according to the assembling method of claim 2, the assembling at the foundation part as well as the general beam top part of the building. The work can be performed with high efficiency.

Further, as the joint (J) used in the above-mentioned assembling method, as described in the third aspect of the invention, a metal fitting (for attaching to the ruler angle (12) fixedly mounted on the beam (11) is used because of its structure. A) and a connecting metal fitting (B) for assembling a pair of upper and lower ALC wall panels (P) that are adjacent to each other by being dropped into the mounting metal fitting (A) from above and used. (A) is bent from one metal plate into a substantially L-shape or a sideways T-shape in side view,
A fixed length (s) slit (18) for dropping the connecting metal fitting (B) into a horizontal plate piece (17) protruding from a vertical plate piece (16) serving as a mounting base for the ruler angle (12).
And the connecting metal fitting (B) is punched out from a single metal plate into a substantially T-shape in a front view, and a fixed width (w1) of the lower half plate piece (19) is set to the slit (18). )
Is smaller than the opening length (s) of the lower half plate (19), and the lower edge of the lower half plate piece (19) is formed as a circular arc groove (14) notched and opened at the upper center of the lower wall panel (P). While modeling the corresponding arc convex curved surface (x1), the upper half plate piece (20) of the connecting metal fitting (B) is also made to have a constant width (w2) larger than the opening length (s) of the slit (18). The upper edge of the upper half plate piece (20) is dimensioned and shaped into an arc convex curved surface (x2) corresponding to the arc concave curved groove (15) opened in the center of the lower end of the upper wall panel (P). Then, the connecting bracket (B) is attached to the slit (18) of the mounting bracket (A).
, And the lower half plate piece (19) of the connecting metal fitting (B) is dropped into the arc concave curved groove (14) of the lower wall panel (P). The remaining upper half-plate piece (20) is replaced with the circular arc concave groove (15) of the upper wall panel (P).
Since they are set to be locked, the circular saw grooves (14) and (15) of the wall panel (P) that can be easily opened by using a circular saw that is common even at the construction site,
The upper half plate piece (20) and the lower half plate piece (1) of the connecting fitting (B)
9) can be locked with each other very smoothly and stably, and despite its excellent workability in assembly, once locked, the beam (11) or other structural frame Even if the wall panel is deformed, the wall panel (P) smoothly rolls due to the arcuate concave grooves (14) and (15), which may damage the wall panel (P) itself and its joint (J). Absent. Seismic isolation is also effective.

Moreover, the joint (J) having the above structure can be mass-produced at a low cost by sheet metal press working, and the connecting metal fitting (B) is attached to the slit (18) of the mounting metal fitting (A) in use. Since it is sufficient to drop it from above, it is very useful as a joint used in large quantities of this kind.

Particularly, if the structure of claim 4 is adopted as the joint (J), the connecting metal fitting (B) can be manufactured more easily, and the arcuate concave curve of the wall panel (P) engaging with the metal fitting can be made. The grooves (14) and (15) can be lightly cut open while using the same circular saw at the construction site without distinguishing the upper and lower pairs, and also as a rolling action of the wall panel (P). However, there is an effect that each individual can be operated uniformly.

Further, if the configuration of claim 5 is adopted,
The lower half plate piece (19) of the connecting metal fitting (B) can be smoothly and stably dropped into the slit (18) of the beam mounting metal fitting (A) for operation, and the connection with the wall panel (P) can be performed. In the stopped state, due to the constant gaps (g1) (g2) secured between the arc concave curved grooves (14) (15) and the plate pieces (19) (20) of the connecting fitting (B), The behavior of the wall panel (P) that follows the deformation of the structural body can be more and more freely and smoothly performed, and the flexibility of the above-mentioned wall panel (P) also greatly improves the workability of assembly. It has a remarkable effect.
