Is a wall panel formed by tightly binding and integrating a frame body provided with binding fasteners connected to the embedded nuts on the back surface of the frame body. In addition to disposing a face material forming a retention space for heat insulation, a spacer for forming a gap for ventilation with the outside of the retention space is provided in the binding portion between the frame body and the lightweight cellular concrete plate. It is characterized by being provided.

Further, the binding fastener is formed in a substantially L-shaped cross section including an inner piece along the inner surface of the frame body and an outer piece along the back surface of the lightweight cellular concrete board, and each piece has a position adjusting length. It is characterized in that holes are formed.

[Operation] According to the wall panel of the present invention, since the frame body is integrated with the back surface of the lightweight cellular concrete plate, the frame body can bear the load to enhance the yield strength of the lightweight cellular concrete.

Further, outside air can be stored or recirculated in the staying air, and the heat insulating effect can be enhanced by the staying space.

In this case, a recess 12 for embedding the head of the bolt 11 is formed on the outer side surface of the vertical frame 3c.

In FIG. 3, the holes 13 formed in the lower frame 3a and the upper frame 3b are connection holes for connecting the frame body 3 to the body insert or the base anchor.

The spacer 8 is formed of wood chips such as plywood, has a thickness of about 5.5 mm, and is fixed to the surface of the frame body 3 with an adhesive or the like.

The face material 6 is formed of plywood, particle board, or the like, and is fixed to the back surface of the frame body 3 with no gaps. In the frame body 3, the stay space 5 is formed between the lightweight cellular concrete plate 1.

Since b is vertically long, lightweight cellular concrete board 1
Even if the positional accuracy of the embedded nut 2 is poor,
The binding fastener 4 can be moved up and down along the mounting hole 4b to absorb the positional deviation.

Similarly, since the attachment hole 4d of the outer piece 4c is formed horizontally long, it is possible to correct the positional deviation between the lightweight cellular concrete plates 1, 1 arranged in parallel.

Then, the wall material 6 is attached to the back surface side of the frame body 3 to assemble this wall panel.

An anchor bolt or the like that has been applied is connected to the connection holes 13 and 13 to construct a wall of the building.

In this case, the lightweight cellular concrete plate 1 can form the outer wall surface of the building and the face material can form the inner wall surface, and the building can be constructed in a short time with almost no finishing work.

Since the lightweight cellular concrete plate 1 and the frame body 3 are integrated, the strength thereof is polynuclear and the wall magnification is 5 times. By the way, in the conventional construction method, a wall body provided with braces has a wall magnification of about 1.5 times.

In addition, outside air can be stored in the retention space 5 or can be recirculated through the gap 7, and by providing the retention space 5, an excellent heat insulating effect can be obtained.

That is, the air stored in the retention space 5 forms a heat insulating layer between the inside and outside of the room, and the inside of the room is warm in winter,
It is possible to keep the temperature low in the summer.

"Effects of the Invention" As described above, the wall panel according to the present invention can achieve the following respective effects.

Since the frame body is tightly bonded to and integrated with the lightweight cellular concrete plate, the drawback of the lightweight cellular concrete plate being weak against the shearing force can be eliminated, and high strength as a panel can be obtained.

When constructing a building, it is possible to construct a wall body in a short time simply by connecting the wall panels of the present invention, without the need to assemble the structural material and apply the lightweight cellular concrete board to the structural material twice. Can be configured.

Since the lightweight cellular concrete plate constitutes the outer wall surface and the face material constitutes the inner wall surface, it is possible to construct a building in a shorter time without the need for surface finishing work of the wall body on site.

Since the retention space is formed between the lightweight cellular concrete plate and the face material, the outside air can be stored in the retention space or recirculated through the gap formed by the spacer,
An excellent heat insulating effect can be obtained by the retention space.
