Description

[Detailed explanation of the invention] A. Industrial field of application This invention is a method for fixing and erecting supports through the shade tree covered by the parapet when installing handrails on the roof of a building, balcony, etc. Regarding structure.

B. Prior Art A parapet of a building is usually covered with a cap to improve its waterproofness and appearance. When a handrail is installed on a parapet with a cap, an anchor member fixed upright on the parapet is usually protruded through the cap, and a cylindrical post of the handrail is fitted and fixed thereto to provide a handrail. .

In this case, the above-mentioned anchor member is also cylindrical, but measures are taken to drain rainwater that has entered the cylindrical support and anchor member onto the upper surface of the cap so that it does not flow down to the parapet surface. ing.

C. Problems to be solved by the invention As a means for draining rainwater that has entered the cylindrical support and anchor members, for example,
As shown in Publication No. 104923, a gasket is provided between the anchor member passing through the cap and the cap to block water from flowing into the cap, and a drain hole is provided on the lower end side of the anchor member or the cylindrical support. This allows water that has entered the inside to be discharged onto the top surface of the Kasagi.

However, since this drainage hole is exposed to the outside on the top of the Kasagi, rainwater can backflow during strong winds, and dirt and dust can also enter and accumulate inside, obstructing drainage and causing corrosion in the area. This resulted in unfavorable results such as a decrease in the durability of the support pillars, and the rust that formed adhered to the caps, deteriorating their appearance.

D. Means for solving the problem The present invention is based on the conventional method in which when a handrail post is erected and fixed on a parapet covered with a Kasagi, rainwater that has entered the inside of the post is drained to the top surface of the Kasagi. Instead of this method, the above-mentioned conventional problems are solved by guiding the intruding rainwater into the inside of the Kasagi and draining it to the side of the parapet above the mounting base of the column anchor member.

That is, the present invention has a cylindrical anchor that penetrates a cap covering a parapet on the roof of a building, etc., and is erected and fixed on the parapet, and a cylindrical anchor that is fitted externally with the lower end positioned inside the cap. It consists of a cylindrical column fixed with a through bolt, and the cylindrical anchor has a water stop plate that seals the inner cavity below the fixed position of the column, and a water drain that connects the top surface of the water stop plate to the outside surface of the cylinder. It has a hole, and is located between the lower end of the column and the base of the cylindrical anchor to maintain watertightness on the outer peripheral surface of the cylindrical anchor, and its drainage end reaches inside the cap on one side of the parapet. This is a handrail support support structure for a building parapet, which is characterized by the installation of boards.

E. Effect: With the handrail support fixing structure of the present invention, a handrail is provided by suspending and fixing the upper and lower horizontal members with bars between the supports erected at predetermined intervals on the parapet. Rainwater that has entered the support and anchor members through the gaps between the penetrating fixing bolts flows down inside the support, flows from its lower end into the drainage plate surface inside the cap, and flows from the drainage end on one side to the side of the parapet. It is discharged into the space facing the Kasagi side board.

The above drainage route is inside the Kasagi, and there is no backflow of rainwater or intrusion of dirt and dust through the exposed drainage holes on the top of the Kasagi, which is the case with conventional methods. This prevents water from penetrating into the parapet portion where the anchor member is attached, thereby preventing infiltration of the parapet portion, thereby inhibiting rusting and corrosion of the lower part of the column and the anchor member.
