Patent Document 1 discloses a method of placing concrete using a combined heat insulating material panel A having a structure in which a composite reinforcing material 7 is integrated with a heat insulating material 6.
However, in Patent Document 1, foam ties (registered trademark) 3 and separators 5, which are metal fittings for mold fastening, penetrate through the heat insulating material 6 and the reinforcing material 7 and protrude to the surface (outside) of the reinforcing material 7. Therefore, there has been a problem that noro (cement water) leaks from the through hole. Moreover, since this noro is a strong alkali and soils the outer surface of the reinforcing material 7, it is necessary to wipe off the noro after curing or to cover the outer surface of the reinforcing material 7 with a finishing material (interior board 11). In addition, since the dual-purpose formwork is held down by the reinforcing material 7, it is necessary to perform the work from the outside of the dual-purpose heat insulating panel A, and a space for assembling a scaffold is required, and there is not enough space between the adjacent house and the like. ) Was difficult to build. In addition, the decorative finish after curing has a problem that the work becomes difficult in the case of a narrow area.

Patent Document 2 discloses a heat insulating wall outside a building in which a cement-based hard material 4 in which a tile 3 as a finishing material is integrated with a heat insulating material 2 is joined.
However, in this patent document 2, since the bolt of a anchor member 5, a nut, the edge part of a separator, etc. appear on the surface of the finishing material 3 as shown in figure, it was not preferable in design. In order to solve this problem, the same processing as in Patent Document 1 is necessary.

Therefore, the applicants of the present application have proposed, as Patent Documents 3 to 5, a panel for combined formwork that can prevent the outflow of noro from the connecting portion.
These formwork combined panels have a configuration in which an exterior finishing material is arranged along a heat insulating material that is long in the vertical direction, and one of the connecting portions at both ends is provided with a polymerized piece, and the other is provided with a polymerized piece. In a state where the adjacent polymer pieces are polymerized to the polymerized pieces, the rod-shaped member can be connected by being screwed into the screw portion of the fixing portion provided inside the face plate portion from the back surface side of the heat insulating material. Therefore, it is possible to easily connect adjacent panels for formwork, and to prevent leakage of leaking from the connection part (fixing part) between the panels, without having to wipe off the exterior finishing material as it is. It can be used as a material.
Also, a space portion is provided on the back side of the face plate portion, a fixing material having a screw portion is attached in the space portion to form a fixing portion, and the rod enters the fixing portion through the rod-shaped member from the concrete placement space. Even in this space portion, leakage to the surface of the face plate portion is prevented.
