Description

[Detailed Description of the Invention] The present invention relates to a wall panel in which a lightweight aerated concrete wall such as an ALC board is formed as a load-bearing board.

Wall panels with lattice-shaped reinforcing bars embedded in them have been known for some time, but if the wall panel becomes large in size, the vertical bars on the tension side connected to the mounting hardware will break, causing ALC to fail at the mounting area. Since it will chip and fall, sufficient structural strength cannot be obtained.

The present invention can obtain sufficient structural strength even when the wall panel becomes large in size, and also has mounting hardware buried near the corners of the panel in which multiple reinforcing bars are buried so that a portion of the reinforcing bars are exposed. , the mounting hardware is connected vertically and horizontally to a plurality of reinforcing bars densely arranged inside the panel near the outer edge, and is connected to the through holes drilled in the base piece of the mounting hardware. To provide a wall panel that is easy to install and has excellent strength by having nuts fixed to the back surface of the base piece.

By the way, when determining the position of the mounting hardware, when a certain horizontal force is applied to a panel of a certain width, increasing the distance between the horizontal support points at the bottom of the panel will reduce the internal stress in the vertical direction. It is effective because it can bear the burden of force.

In addition, in general, tensile stress is mainly borne by the reinforcing bars, so for members with small cross sections such as steel bars, multiple bars are required to obtain the necessary cross section, and it is rational to closely connect them to the mounting hardware.

The present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is a schematic diagram showing the internal reinforcement of a load-bearing wall panel A according to the present invention. As shown in the figure, reinforcing bars 1 made of, for example, steel bars are arranged in a grid pattern inside the panel A.

In addition, a plurality of reinforcing bars 1 are densely arranged inside the load-bearing wall panel A near the four outer edges thereof. By arranging the reinforcement densely in this way, sufficient structural strength can be obtained even if the wall panel A becomes large in size.

Incidentally, mounting hardware 3, 3 is attached to both sides of the upper end surface 2 of the wall panel A in the longitudinal direction, with a portion thereof exposed to the outside.

The mounting hardware 3 is composed of a flat base piece 4, a plurality of long nuts 5 fixed to the back surface of the base piece 4, and mounting pieces 4' connected to the reinforcing bars 1.

The mounting piece 4' of the mounting hardware 3 is connected by welding to not only the main reinforcement 1a but also the horizontal reinforcement 1b of the reinforcing reinforcement 1, and is attached to the end of the panel A with a part thereof exposed to the outside. .

As shown in FIG. 5, it is also possible to make one side end of the mounting piece 4' of the mounting hardware 3 long and connect and fix it to the plurality of horizontal bars 1b through the mounting piece 4' by welding or the like. I do not care. In this case, the mounting strength is further improved.

By the way, on both longitudinal sides of the upper end surface 2 of this wall panel A, through holes 7, 7, which are bored in the base piece 4 in correspondence with the positions of the long nuts 5, 5 of the mounting hardware 3, are exposed to the outside. It turns out.

Next, at the lower end of this load-bearing wall panel A, as shown in FIG. 7, rectangular grooves 6, 6 are formed which are cut out across one side of the load-bearing wall panel A and the lower outer peripheral surface. The mounting hardware 3 is attached to the bottom of the grooves 6, 6 in such a way that a part thereof, that is, a through hole 7, 7 bored in the base piece 4 corresponding to the position of the long nut 5, is exposed to the outside. It is being

This installation is similar to the installation of the mounting hardware 3 on the upper end face of the panel A.

In order to prevent the load-bearing wall panel A from chipping, it is preferable to reinforce the grooves 6, 6 by driving reinforcing metal fittings formed of thin metal fittings and having approximately the same shape as the grooves 6.

The load-bearing wall panel A according to the present invention is installed as shown in FIG. 9 as an example.

That is, upper and lower joint fittings 8,
9, and is supported by the building frame 14 by these joint hardware 8,9.

The upper joint hardware 8 has a metal fitting insertion hole bored in the flat steel, and one side of the metal fitting 8 is attached to the top of the load-bearing wall panel A with a screw 1.
0, and the other side is fixed to a beam of the building frame 14 with bolts and nuts 11.

The lower joint fitting 9 has a U-shaped cross section and is provided with a stiffener, and metal fitting insertion holes are formed in the upper and lower flanges. This lower joint hardware 9 is fitted into the groove 6 at the lower end of the load-bearing wall panel A, and is fixed to the load-bearing wall panel A by screws 10 inserted through the upper flange. 11 bolts and nuts for other foundations, lower beams, lower panels, etc.
It is fixed by.

Since the upper and lower joint hardware 8 and 9 have the above configuration, the external force in the horizontal direction is applied to the two joint hardware 8 and 9 on the upper and lower sides.
The external force in the vertical direction is borne and supported by the two joint hardware 9 on the lower side. That is, the upper joint fitting 8 is made of flat steel and is bent in the vertical direction, so that it does not substantially transmit force.

Incidentally, since the joint hardware 9 in the groove 6 formed at the lower end of the load-bearing wall panel A does not protrude outward from the side surface of the panel A, if the skirting board 12 is attached to cover the groove 6, the finish can be completed. It can be used as a surface.

Incidentally, FIG. 8 shows another embodiment of the wall panel according to the present invention.

In this embodiment, the lower end of the panel is cut out to form two grooves 6, 6, and the bottoms of the grooves 6, 6 have transparent holes bored in the base piece 4 corresponding to the positions of the long nuts. The holes 7, 7 are exposed to the outside, and two rectangular notches 13, 13 are formed at the upper side of the panel A, and the through holes 7, 7 are formed in the side walls 14, 14 of the notches 13, 13. The long nut 5 and the base piece 5 are buried so that they are exposed.

With this kind of wall panel A, even if the upper end of the panel is above the beam due to the waterproof rise of the top floor, it can be attached to the building frame with sufficient measures.

Thus, the load-bearing wall panel according to the present invention has the above structure, and according to this invention, even if the panel becomes large, the plurality of reinforcing bars are densely arranged inside the panel near the outer edge. For example, even if a large force is applied locally near the mounting hardware during an earthquake, there will be no local destruction due to rupture of the reinforcing bars, and the external stress can be channeled through the internal reinforcing bars to the lower horizontal members, making it possible to obtain sufficient structural strength. can. Furthermore, the multiple reinforcing bars 1 arranged inside are equipped with mounting hardware for mounting wall panels that are partially exposed to the outside, so the panel has the advantage of being easy to install on the building frame. be.
