2. Description of the Related Art Conventionally, various constructions for erecting a handrail on the edge of a building have been performed. Particularly, when a cap is provided on the upper surface of a concrete parapet, a handrail support is attached to the cap. It is difficult to establish. That is, in general, the upper surface of the coping has a structure that is inclined downward inward in order to make rainwater flow down inside the building, but the inclination angle is not constant, and the work site and Since it is different depending on the place of establishment, if you try to vertically build a support for the handrail to be established on the top of the cap, the end face of the lower end of the support must be cut at the site according to the top angle of the cap,
The work is difficult and requires the skill of the worker, and there are problems such as a long working time and poor workability.

[0003]

Therefore, as a method of improving workability, a structure is employed in which a wedge-shaped spacer is inserted between a cap and a lower end of a pillar to vertically establish and fix the pillar. Many kinds of spacer members must be prepared according to the inclination angle of the place, and there is a problem that the material cost is increased.

[0004] The present invention has been made in view of the above problems, and regardless of the angle of inclination of a heddle constructed for the vertical descent, a simple angle adjustment at the site allows the support for the handrail to be mounted on the upper surface of the heddle. It is an object of the present invention to provide a handrail support structure in which the number of materials is small and workability is improved, and a handrail support angle is adjusted.

[0005]

According to the present invention, there is provided a railing support structure according to the present invention, in which a handrail support is provided on a building fixed to an edge of a building. A pedestal portion which is fixed to the position directly or via a reinforcing attachment member, and has a large-diameter arc-shaped concave surface having a center upward in the vertical direction of the water drop gradient on the upper surface of the central portion, and has a raised structure. A base member formed by penetrating a fastening bolt insertion hole at the center of the arc concave surface, a short cylindrical edge fitted to the lower end of the handrail support, and a convex arc contact end surface for closing the end. The convex arc contact end surface forms a convex surface of the same curvature facing the arc concave surface of the base member, and a fastening bolt insertion slot is drilled in the center portion. A strut end cap member, and a projection protruding from the base member The nut is screwed into the end of the fastening bolt by adjusting the relative position of the contact surface between the arcuate concave surface and the convex arc contact end surface of both members by inserting the bolt into the fastening bolt insertion slot of the column end cap member, It is a feature that the center angle of the handrail support of the end cap member with respect to the base member can be changed, and one or a plurality of racks are provided on both sides of the fastening bolt insertion hole of the arcuate concave surface of the base member. The engaging teeth are arranged side by side in the arc direction, and the rack-shaped engaging teeth of the base member are meshed with the rack-shaped engaging teeth of the base member on both sides of the fastening bolt insertion slot on the convex arc contact surface of the column end cap member. It is characterized in that a meshing structure is formed in which the engagement teeth are arranged side by side in the arc direction at equal pitches, each of which is several hills more than the rack-shaped engagement teeth of the base member. A non-slip structure such as satin finish or knurling may be formed on the arcuate concave surface of the base member and the convex arc abutment surface of the column end cap member.

[0006]

According to the above-mentioned construction of the support for the handrail, the base member and the end cap member of the establishment angle adjusting structure have arc-shaped opposing surfaces having the same curvature, which are composed of an arcuate concave surface and a convex arc contact surface. Therefore, the assembling angle of the two members can be adjusted by changing the contact position between the arcuate concave surface and the convex arc abutment end surface. The rack-shaped engaging teeth are meshed with each other at the selected angular position, and the angle is reliably fixed.

[0007] Therefore, by adjusting the inclination of the two members in accordance with the inclination angle of the heddle that is configured for the vertical descent, the two members are fastened and fixed, so that the handrail strut can be vertically mounted on the upper surface of the heddle having a different inclination depending on the site. Be able to establish.
