The insertion preventing portions 32, 33 are provided with protrusion preventing protrusions 32e, 33e, respectively. The connecting bar 30 is formed in the same form as the T bar 20, but differs from the T bar 20 in that it does not have a binding hole 24.

As shown in FIG. 1, FIG. 2, the mutually opposing mutually formed assembly tie (the same level among the inside / outside formwork heat insulation panel P installed so that an inner formwork Mi and an outer formwork Mo may be constructed | assembled) Bound by 40). The assembly tie 40 is formed in a clamp shape and has left and right binding ends 41 and 41 that are bent at substantially right angles at both ends thereof, and these binding ends 41 and 41 are formed by a plurality of T bars 20. It is selectively fitted in the binding hole 24... And connected.

Next, with reference to FIG. 1, FIG. 13 mainly, the method of building the formwork M of a wall using the formwork heat insulation panel P concerning this invention is demonstrated.

In constructing the outer formwork (Mo) and the inner formwork (Mi), which are installed with a concrete pouring space (S), one side of these, in this embodiment, first the installation of the outer formwork (Mo) is the inner formwork (Mi) This is done before. That is, the formwork combined heat insulation panel P of the outer formwork Mo is piled up from the lowest end to the uppermost end through several intermediate | middle ends. In this stacking operation, the position where the upper and lower formwork heat insulating panels P are stacked is placed on the second reinforcing material 8 .. and the formwork heat insulation panel P is zigzag. When stacking by the second reinforcing material 8... As a guideline, the relative position of the upper and lower formwork thermal insulation panel P can be accurately positioned and accurately stacked.

The upper and lower formwork thermal insulation panels P and P are respectively connected via the T bars 20 as described above. By stacking up in this way, when the outer formwork Mo is provided, the inner surface of the outer formwork Mo, that is, the surface in contact with the pouring concrete, of the insertion hole 2 provided in the lower portion of each formwork-insulating panel P A brittle thin wall 4 covering the insertion opening 5 is exposed to the outside, and the position of these thin walls 4 is indicated by the first reinforcement 6 so that it can be easily seen from the outside. As shown in FIG. 15, the tie ends 41 of the assembly ties 40 are pressed against the thin wall 4 and inserted into the insertion holes 2, and the assembly ties 40 are pushed downwards. The binding end 41 of 40 is inserted into the binding hole 24 of the T-bar 20, and it connects, and as shown in FIG. 1, FIG. 13, the inner surface of the outer mold Mo (the casting side surface of concrete) ), The tie end 41 can be connected to one of the plurality of assembly ties 40.

As described above, after combining the plurality of assembly ties 40... By integrating into the plurality of formwork combined heat insulating panels P of the outer formwork Mo, the formwork combined heat insulating panel P for constructing the inner formwork Mo. The other binding portion 41 of the assembly tie 40 is connected to the binding hole 24 of the () by pressing and breaking the thin wall 4 in the same manner as described above, and the other side of the assembly tie 40. The coupling part 41 of the inner mold (Mo) can be installed in order from bottom to top one by one while passing through the insertion hole (2) to the binding hole (24).

A first reinforcing material 6 'is provided on the outer surface (surface on the opposite side of the concrete placing space S) of the outer mold Mo and the inner mold Mi provided as shown in FIG. 1, and these molds Mo , Mi) can confirm the position of the some assembly tie 40 which binds these from the outer side.

By the way, when producing the formwork combined heat insulating panel P constituting the outer formwork (Mo) and the inner formwork (Mi), conventionally T-bar 20 coated with an adhesive on the upper surface vertical slit 10 of the panel body (1) Although the lower insertion part 23 of () was inserted, it hardened overnight so that the T bar 20 might not shift, and it waits for hardening of an adhesive agent, However, in this Example, as mentioned above, the panel main body 1 Since only the T-bar 20 is inserted into the upper surface vertical slit 10, the formwork combined heat insulation panel P can be produced, and the production cost can be greatly reduced, and therefore the formwork M is quickly constructed at low cost. can do.

In addition, in the past, in the case of installing the inner and outer formwork insulation panels, the insulation panels were installed while connecting both panels with assembly ties every time the insulation panels were stacked one by one. Although it was inefficient because two workers on both sides of the installation had to perform the installation work, or one worker had to perform the installation work while moving both sides of the inner and outer insulation panels alternately, in this embodiment, Likewise, one side, that is, either one of the outer and inner formwork (Mo, Mi) is installed in advance, and the formwork combined heat insulating panel (P) of the formwork (outer formwork (Mo) or inner formwork (Mi)) of one side installed in this way. And a plurality of assembly ties 40... Which are then combined with the formwork insulation of the other formwork (inside formwork (Mi) or outer formwork (Mo)). Null (P ...) to be installed, while it is possible to bond the assembly tie (40 ...), one worker is without moving the inside and outside of the mold can be performed with the installation of these mold (M). In addition, when the installation of the outer and inner molds (Mo, Mi) is completed, concrete is poured into the concrete placing space (S) therebetween, but the thin wall (4) of the hole for inserting the thermally insulating panel (P) for formwork (2) ) Is press-crushed by the tie end 41 of the assembly tie 40, or because most of its inserts 5 are covered by a thin wall 4, and the gap between the inserts 5 is very small, It is possible to suppress the cement paste from entering into the insertion hole 2 into which the assembly tie 40 is inserted at the time of concrete pouring, and the cement paste enters into the insertion hole 2 into which the assembly tie 40 is not inserted. Since there is no work at all, the penetration of the cement paste does not cause a decrease in the heat insulating performance of the formwork heat insulating panel P.

As described above, concrete is constructed by placing concrete in the concrete placing space S between the outer and inner molds Mo and Mi, but after the construction of the concrete spheres, the outer and inner molds Mo and Mi are It is used as a heat insulation wall of a building as it is without peeling off.

Further, according to this embodiment, since the inner surfaces of the outer and inner molds Mo and Mi are flat surfaces, and only the rod-shaped portion of the assembly tie 40 that is the binding member is present in the concrete placing space S, By reducing the volume of the binding member to suppress the cross-sectional defects of the concrete sphere, it is possible to build a high-strength concrete sphere excellent in the pourability of the concrete, and also does not generate rock pockets and the like.

As mentioned above, although the Example of this invention was described, this invention is not limited to the Example, A various Example is possible within the scope of this invention.
