A plurality of connecting reinforcing bars 10, ... Are arranged along the longitudinal direction of the upper end of the cloth foundation A at regular intervals of two to three rows.

The diameter of reinforcing bars 10, ..., Rebar volume and rebar spacing shall be decided by considering the scale of the building.

The outer wall B and the inner wall C on the first floor are respectively formed on the cloth foundation A having the above structure.

The outer wall B of the first floor is a three-dimensional wire netting panel 2 with a heat insulating material, and a three-dimensional wire netting panel 1 is attached to the inside from the outside of the room at the upper end of the cloth foundation A.

By forming joints vertically and horizontally on the outdoor side surface of the outer wall B, the outer wall B is prevented from being cracked and decorated.

In this case, since the concrete or mortar 9 on the outdoor side of the outer wall B covers the heat insulating panel 6, it is not necessary to make it thicker than necessary.

Therefore, joints can be provided on the outer side of the outer wall B to freely enhance the decorativeness of the outer wall.

On the other hand, since the concrete or mortar sprayed on the interior side of the outer wall B forms a structure integrally with the three-dimensional wire mesh panel 1, it should be carefully constructed.
If necessary, reinforcing bars (not shown) may be arranged vertically and horizontally inside the three-dimensional wire mesh panel 2 with heat insulating material, or two to three three-dimensional wire mesh panels 1 may be installed to enhance the earthquake resistance of the outer wall B. .

The connecting wire mesh 11 is installed across both the three-dimensional wire mesh panel 2 with a heat insulating material on the cloth foundation A or the inner wall C and the half-PC floor panel 3 on the floor D, and if necessary, the three-dimensional wire mesh panel facing each other across the wall. It is integrally welded to 2,2.

In this way, the three-dimensional wire mesh panel 2 with the heat insulating material of the cloth foundation A and the floor D
Since the half-PC floor panel 3 and the half-PC floor panels 3, 3 of the floor D are integrally joined, the rigidity of the joint portion is significantly increased.

In addition, if necessary, reinforcing reinforcing bars (not shown) may be arranged vertically or horizontally on the upper side of the half PC floor panels 3 or 3 or the half PC floor panel 3
The rigidity of the floor may be significantly increased by installing a plurality of three-dimensional wire mesh panels 2 with a heat insulating material on top of each other to increase the floor thickness.

In addition, the space 13 between the half-PC floor panels 3, 3 and the three-dimensional wire mesh panel 2 with heat insulating material laid on it is used as an installation space for indoor wiring and water supply / drainage pipes, and the surrounding area is a heat insulating material such as urethane. The heat insulating property may be enhanced by filling the same.

In addition, the floor D on each floor of the second floor and above is located on the upper end portions of the outer wall B and the inner wall C in substantially the same manner as the floor D on the first floor, the half-PC floor panel 3 and the connecting wire mesh 1
1 and 12 are used (see FIGS. 16 to 19), and a roof 14 is formed on the floor D on the top floor and is waterproofed (see FIGS. 20 and 21). ).

〔The invention's effect〕

Since the present invention is configured as described above, it has the following effects.

Since the heat insulating material is installed in the outer wall, the inner wall, and the floor of each floor almost continuously without being cut in the middle, the heat insulating effect is extremely high.

Especially, since the heat insulating material of the outer wall does not drop at the floor level, it is possible to prevent dew condensation due to the heat bridge in this portion.

The main function of the concrete or mortar sprayed on the outside of the three-dimensional wire mesh panel with heat insulating material on the outer wall is to cover the heat insulating panel.Because it can be regarded as a non-structured structure, joints are provided vertically and horizontally in this area. However, there is no structural problem.

In addition, the outer wall can be easily reinforced by installing two or three three-dimensional wire mesh panels inside the three-dimensional wire mesh panel with heat insulating material, and the floor is also installed by stacking multiple half-PC floor panels. Since it can be reinforced by this, the earthquake resistance can be remarkably enhanced.

Furthermore, since half-PC floor panels are used for the floor, the work of removing the floor formwork can be omitted, and workability is extremely good.
