In the figure, 1 is a main wall mold, 2 is a wooden mold member, 3 is a temporary frame member disposed on the inner surface side of the mold member 2, and the temporary frame member 3 is lightweight. It is made of a plate-shaped elastic member such as Styrofoam or urethane resin in order to improve workability during molding and release.

Reference numeral 4 denotes a stopper formed of a leaf spring having a U-shaped cross section as a connecting means. The stopper 4 is provided with a recess 4 a having a total thickness of the formwork 2 and the temporary frame member 3. ing. The temporary frame member 3 and the mold frame member 2 are combined with the inner surface of the mold frame member 2 and the non-recessed back surface of the temporary frame member 3, and the side surface is sandwiched in the recess 4 a of the stopper 4.

FIG. 4 is a perspective view showing another embodiment of the coupling means, in which a concave portion 4b into which both ends of the temporary frame member 3 are fitted is integrally formed with the mold frame member 2a. The temporary frame member 3 is inserted into the concave portion 4b while sliding on the surface of the mold frame member 2a, and the inner surface of the mold frame member 2a and the non-recessed back surface of the temporary frame member 3 are joined together.

Further, the material of the mold frame members 2 and 2a and the temporary frame member 3 is not limited to the above-mentioned embodiment, but metal, resin or the like may be used.

In this way, by providing the coupling means for integrating the mold frame member 2 and the temporary frame member 3, when attaching the temporary frame member 3 to the mold frame 2, as in the conventional case, an adhesive or an adhesive is used. The main wall formwork 1 can be easily assembled by simply sandwiching the formwork 2 and the temporary frame member 3 in the recess 4a without requiring heat welding.

The temporary frame member 3 is provided with a hole 3a inside and is formed so that the surface thereof has an uneven shape as a whole. As shown in the cross-sectional view of FIG. 2 showing an example of use, the ready-mixed concrete poured into the mold enters the hole 3a of the temporary frame member 3 and is hardened to harden the concrete main wall 20 formed. As shown in FIG. 3, projections 20a corresponding to the uneven shapes of the holes 3a of the temporary frame are formed on the surface. Therefore, the mortar (not shown) for tile application, which is applied to the surface of the concrete main wall 20, is mechanically fitted to the protrusion 20a, and it is possible to effectively prevent peeling.

It should be noted that the temporary frame member 3 only needs to be provided with one that forms an uneven shape for preventing separation on the main wall 1, and instead of the cylindrical hole 3a in the above-mentioned embodiment, it has a corrugated shape or a honeycomb shape. It can also be in the form of a shape.

In particular, if the temporary frame member 3 is made of urethane resin, it is elastically deformed at the time of releasing the mold, and therefore, as shown in FIG. 5, the uneven shape of the surface can be a dovetail groove or a dovetail groove. Further, when the stopper 4 is sandwiched or the temporary frame member 3 is inserted into the concave portion of the mold member 2, even if the stopper 4 or the concave portion is small, the thickness of the mold member 2 or the temporary frame member 3 should be taken into consideration. Instead, it is possible to mount using elasticity.
