Description

This invention is mounted on a top surface at a top projecting corner of a concrete structure to prevent rainwater that has fallen onto the top surface of the concrete structure from flowing down from the wall surface of the concrete structure. It relates to water return materials used in particular.

Drainage materials have traditionally been installed on top of the top surface at the top protruding corners of concrete structures to prevent rainwater from flowing from the top of the structure along the exterior wall, and to allow rainwater to fall away from the wall. Various methods have been proposed (for example, Patent Document 1).

When considering the preservation and protection of the external walls of concrete structures, the influence of rainwater on the walls is significant and is a major factor in their deterioration.

The effect differs depending on the wall finishing material.Rainwater does not penetrate into film-forming exterior wall coating materials, but rainwater penetrates into the mortar joints of exposed concrete and exterior wall tiles, and calcium hydroxide from the concrete and mortar flows out. This results in roughening and thinning of the surface layer.

When rainwater remains on the walls of concrete structures, mold quickly forms. This mold is quickly killed by ultraviolet rays, but the residue of the dead mold remains on the wall, and when it gets wet with rainwater, the mold grows and becomes a black stain that becomes a contaminant on the wall. This mold growth cycle is responsible for the dark contamination that is spreading on the north wall of the concrete structure. Mold can cause damage to walls.

If there is no wind, rainwater falls vertically, but when it hits a flat surface, it bursts and spreads horizontally, creating a flow toward the outside wall. On the roof parapet top surface, rainwater that falls near the top corner will run down the wall. Furthermore, when there is a large amount of wind or rain directed toward the outside of the building, a large amount of rainwater falls on the exterior wall surface, and the rainwater flowing down the wall surface deteriorates the wall surface.

There are also products that can alleviate these symptoms. For example, if the width of a metal cap that waterproofs the top of the cap and protects its members is wider than the width of the top, the influence of rainwater is reduced. In addition, the top angle draining hardware is designed to allow rainwater to fall away from the wall so that it does not flow from the top along the outer wall. This type of crown draining hardware also serves as the terminal material for waterproofing material and can be easily installed, so it is often used in waterproofing repair work.

In this type of roof gutter, all the rainwater that hits the parapet and heads for the outside falls to the bottom of the wall. Fallen water droplets are dispersed by the wind pressure caused by the fall and by the influence of natural wind, and this tendency becomes stronger as you go downstairs. A portion of the dispersed rainwater falls onto the top of the wall or handrail wall below the floor, causing deterioration of the wall surface.

Therefore, the present invention provides a crown water return material that is used by being mounted on the top face at the top protruding corner of a concrete structure, and the rainwater that falls from the crown water return material is used in the concrete structure. The purpose is to solve the problem of contact with the wall surface of objects, which can cause deterioration of the wall surface. That is, it is installed on the top surface of the top corner of the concrete structure to prevent rainwater that has fallen onto the top surface of the concrete structure from flowing down from the wall surface of the concrete structure. The purpose is to suggest water return materials that can be used.
