な為に不充分な施工が行われ易い難点があつた。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for fixing joint material used in pouring concrete for floors and the like. Conventionally, joint fillers have always been used to prevent cracks caused by shrinkage of concrete. As this joint material,
Various types have been proposed taking into account functionality, construction advantages, aesthetics of the finish, etc. For example, the main body of the joint material is a rectangular elastic body made of sponge, elastite foamed synthetic resin, etc., metal legs are attached to support it on the rough concrete surface, and the legs are opened and closed to form the joint material. It is known that the height of the material can be adjusted. When using this joint material, the height of the joint material must be adjusted to suit the water system by opening and closing the legs, and the legs must be fixed to the rough concrete surface with mortar. If the legs are not properly fixed, the joint material may work when concrete is poured, or
Alternatively, there is a possibility that the joint material may be bent at an intermediate position between the legs. Additionally, the mortar used to secure the legs must be prepared at the work site, or prepared elsewhere and transported to the work site.
Since a large amount of mortar is used, especially when constructing a building, the work is often carried out in parallel with other work, which often causes inconvenience, for example, in the use of a work elevator. Furthermore, because the on-site work is difficult, there is a problem that inadequate construction is likely to be carried out.

は防止できる。 Next, the joint material fixing method of the present invention will be explained with reference to FIGS. 6 and 7. As shown in FIG. 6, joint material fixing blocks 1 of the present invention are placed at predetermined intervals on a roughly cast concrete floor surface. At this time, in order to prevent the block 1 from moving during concrete pouring, it is desirable to interpose some mortar on the lower surface of the block. It is assumed that two pairs of blocks 1 are arranged at locations where the joint material A intersects. Next, insert the joint material A into the gap 3 of the block while leveling it with a water system or the like. The height of the joint material can be easily adjusted by filling the gaps 3 between the blocks with mortar or the like. In addition, in cases where the joint material A must be placed high and there is a risk that the upper part of the joint material may sag during concrete pouring, as explained in the first embodiment and shown in Fig. 7, If the upper part of the joint material A is supported using the joint material support member 4, accumulation of the joint material can be prevented.

Alternatively, it is possible to effectively prevent the occurrence of deflection, etc., and the work on site is extremely simplified and facilitated, so that troubles during construction can be reduced.
