Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail mounting structure which can improve the work efficiency of handrails by using a handrail curtain plate binding material in which handrails are integrally fixed to a curtain plate in advance.

[0002]

2. Description of the Related Art For example, as shown in FIG. 5 and FIG.
It is formed by a panel body p protruding outward from one wall surface w of the housing complex h and having an outer end supported by a beam-shaped frame member a parallel to the wall surface w.

Further, the outer surface of the frame member a is conventionally formed by the frame member a.
The handrails e of the floor corridor c are attached to the panel body at the lower ends of the plurality of columns e1 ... It was formed by attaching to the upper surface of the outer end portion of p using a screw or the like.

[0004]

However, in the conventional one in which the curtain plate d and the pillar e1 of the handrail e are separately mounted on site, the number of screw fastening portions is increased, which requires a great deal of labor for construction. In addition to that, the configuration tends to be complicated,
Since the construction efficiency was poor and the number of screws was large, the construction accuracy was likely to be poor.

According to the present invention, the handrail can be attached by fixing the above-mentioned curtain plate of the handrail curtain plate binding material in which the handrail is previously integrally fixed to the curtain plate by using the mounting pieces of the fixing metal fittings arranged on the frame member. Basically, the handrail can be erected only by fixing the curtain plate, for example, the location of the screw stop can be significantly reduced, the construction efficiency can be improved, the construction can be simplified, and the poor construction accuracy can be reduced. The purpose is to provide.

[Function] A fixing bracket having a mounting piece is arranged on a frame material of an overhanging floor-like portion such as a corridor on the upper floor, stairs, and balconies, and a handrail is previously provided on a long curtain plate capable of shielding the outer surface of the frame material. The handrail is attached by fixing the curtain plate of the handrail curtain plate binding material that is integrally fixed using the mounting piece. In this way, the handrail can be attached at the same time by fixing the handrail curtain plate binding material with screws, for example, so that the construction work is much more complicated than the conventional one in which the handrail and handrail were installed separately. The work efficiency can be improved, and the curtain plate, the handrail, and the mounting structure can be simplified, and the defective construction accuracy can be significantly reduced.
