ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing a heat insulating concrete structure. Conventionally, structures shown in FIGS. 1 and 2, for example, have been proposed as concrete structures. 1st
In the figure, a plate 6 is fixed to one side of a pre-formed reinforced concrete layer 1 with nails 5 via blocks 3 and constructed. In Figure 2, a moisture-proof layer 7 is adhered to one side of a pre-formed reinforced concrete layer 1 using an adhesive or the like, and a heat insulating material 8 is attached to the concrete layer 1 using concrete nails 4 or hole-in anchor bolts through a sandwich 3. This is a heat insulating concrete structure constructed by fixing the plate body 6 to the braces 3 with nails 5, etc.

る。 However, with the above construction method, the fixing force of the board to the concrete layer is weak, and the board easily falls off or peels off. Also, in order to fix the board, skilled craftsmen install the board one by one on site. The work efficiency is low, and there are large variations in the mounting strength of the plates, resulting in a lack of reliability. Further, the blocks 3 and the like create a space between the concrete layer 1 and the plate 6, which causes internal condensation and increases the wall thickness.

耐えることができる。 In this method of constructing a concrete structure, a board 6 having a sanderch structure, in which a surface material 11 made of a steel plate is laminated on both surfaces of a heat insulating board 8 made of a synthetic resin foam board, is used as a formwork board for concrete pouring. This plate body 6 has its end surfaces abutted against each other, and the coupling plate 1 straddles grooves 12 and 12' formed in the two end surfaces.
0 is fitted and joined together. Integrated plate 6,
6 are arranged at a predetermined interval on one side of the reinforcing bars 2 that have been arranged in advance or on one side of the position where the reinforcing bars are arranged, and one end of the rod-shaped stopper 9 is fixed to the coupling plate 10. The tip is locked to the reinforcing bar 2. Concrete is then placed in contact with the plate 6 to construct a concrete structure in which the plate 6 is closely fixed to one side of the concrete layer 1. At this time, the plate 6
are reinforced with the surface material 11 and have high strength, and are integrally joined by the connecting plate 10, and the connecting plate 10 and the reinforcing bar 2 are connected with the rod-shaped fasteners 9, so that when concrete is poured, can withstand lateral pressure.

The plate body 6 has moisture-impermeable steel plates laminated on both sides of the heat insulating material, and has high strength, and the part where the coupling plate is fitted is hard to be damaged, and the fixing force by the joining and rod-shaped fasteners is exerted without impairing.
In addition, it is possible to provide heat insulation and moisture proofing properties at the same time after concrete is poured, without requiring any additional construction work, and the interface between the base and plate is in close contact with no condensation, and no fasteners are exposed on the plate surface. It is possible to streamline the finishing process and expand the effective space.
