Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a connecting structure of a capstone that is firmly connected to a handrail installed on a balcony, veranda, etc. and has excellent rain protection.

[Conventional technology]

Generally, in order to install handrails on balconies, verandas, etc., handrail posts are erected on the floor at predetermined intervals, and multiple caps are connected via these handrail posts. , for the handrail support,
Tubular members are often used in consideration of cost and the like. As shown in FIGS. 1 and 2, a conventional connection structure for fixing a cap to a tubular handrail post 2 is a support bracket attached to the upper end of a tubular handrail post 2. Fix 4 and Kasagi 6
The ends of the support bracket 4 are placed on the upper surface of the support bracket 4, covered with a bracket cover 8, and the open ends on both sides are fixed to the support bracket 4 with screws.

[Problem that the idea aims to solve]

However, in the conventional connection structure described above, the support bracket 4 is simply fixed to the upper end of the handrail column 2, and the lower half of the bracket cover 8 is placed on the support bracket 4. Since it is simply fixed by joining the upper end side of the cap 6 and abutting the open end side against the support bracket 4, there is a gap between the contact area between the support bracket 4 and the handrail post 2 and the bracket cover. 8
Rainwater easily enters from the open end of the handrail, corroding the inside of the handrail post 2 and the cap 6, and if the cap 6 is not firmly connected and the cap is gripped and turned, the screws are likely to loosen and rattle. was. On the other hand, as a solution to these drawbacks,
It has also been proposed that a cylindrical connecting bracket is attached to the top end of the handrail post, and this bracket closes the opening at the top end of the handrail post (see Japanese Utility Model Publication No. 11460/1983). In the conventional example, since the bracket is formed in a cylindrical shape, fixing the cap requires the troublesome work of inserting a long cap into the cylindrical part of the bracket and filling it with airtight material. However, since the bracket and support are directly screwed together, corrosion due to rainwater intrusion cannot be prevented. The purpose of the present invention is to solve the above-mentioned drawbacks of the conventional technology, and to prevent rainwater from entering the handrail support and the inside of the cap, thereby preventing corrosion of the handrail, and preventing the cap from shaking during use. To provide a connecting part structure of a capstone that can be firmly connected to a handrail support without any problems.
