By forming joints vertically and horizontally on the outdoor side surface of the exterior wall B, crack prevention and decoration of the exterior wall A are intended.

In such a case, since the concrete or mortar 9 on the outdoor side portion of the outer wall B covers the heat insulating panel 6, there is no need to make it thicker than necessary.

Therefore, joints can be provided on the outdoor 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 indoor side of the exterior wall B is to be integrated with the three-dimensional wire mesh panel I to form a structure, it shall be carefully constructed.

〔Effect of the invention〕

Since the present invention has the above configuration, it has the following effects.

The insulation is extremely effective because the insulation is installed almost continuously on the exterior walls, interior walls, and floors of each floor without any breaks.

In particular, since the insulation material on the outer wall is not missing at the floor level, it is possible to prevent condensation due to heat bridges in this area.

The main function of the concrete or mortar sprayed on the outdoor side of the three-dimensional wire mesh panel with insulation material on the exterior wall is to cover the insulation panel, and since it is considered a non-structural body, there are joints 1 2 4 vertically and horizontally in this area. Even if ゜ is provided, it will not cause any structural problems.

In addition, the outer wall can be easily reinforced by stacking two or three three-dimensional wire mesh panels on the inside of the three-dimensional wire mesh panel with insulation, and the floor can also be ditched and installed by stacking multiple semi-PC floor panels. By doing so, it can be reinforced and earthquake resistance can be significantly improved.

Furthermore, because the floor is made of disposable PC floor panels,
The work of removing the floor formwork can be omitted and the work efficiency is extremely high.
