[Effect of device]

 As described above, according to the present invention, the handrail can be easily attached by integrating a plurality of blocks and inserting and fixing the lower end portion of the column into the column receiving hole.

For example, by inserting the engaging convex portion of the convex block into the engaging concave portion of the concave block and mounting the wedge in the wedge insertion groove, the concave block and the convex block are prevented from being disengaged from each other and integrated. Can be transformed.

Since the engaging convex portion is provided with a strut receiving groove that penetrates vertically in the surface facing the concave block to be engaged, the lower end portion of the strut of the handrail can be divided into a concave block and a convex block. The concave and convex blocks are integrated. Alternatively, by integrating the concave block and the convex block and then inserting and fixing the lower end portion of the supporting column of the handrail into the column receiving groove, it is possible to easily install the handrail on site.

Particularly, by providing the support ribs, the handrail installation work can be further facilitated and speeded up. Further, the concave block has a plurality of engaging concave portions, and the convex block has a plurality of engaging convex portions that respectively engage with the plurality of engaging concave portions. For example, it is possible to easily and quickly install the handrail having the main strut and the retaining strut.

Since the amount of concrete, mortar, etc. used on site may be small, the concrete and mortar can be rapidly cured and solidified, and stable fixation of the handrail support can be accelerated.

In particular, the mortar surrounds the column supporting ribs attached to the one block and the lower part of the column of the handrail, and the configuration of the mortar filling groove is such that the solidified mortar is prevented from coming off. The durability of the integrated block and the attached handrail is excellent, and the filling amount of mortar etc. into the mortar filling groove is about one-fourth that of the conventional on-site method, and curing solidification proceeds quickly. Therefore, the handrail installation work can be done easily and quickly.
