BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rainfall structure on a wall of a building to which a metal panel made of a metal sheet is attached.

[0002]

2. Description of the Related Art Recently, as a wall panel forming an outer wall surface of a building, a shallow box-shaped metal plate wall panel in which bent pieces are continuously provided around four sides of a main plate has been widely used. When a wall surface is formed using this wall panel, a hemp panel made of a metal plate having the same configuration as that of the wall panel is used for a hemming portion at the upper end of the wall such as a parapet portion. In the rain-closing structure of the coping panel portion, as in the case of the wall panel, a sealing material is filled in a gap between adjacent panels to form a joint for waterproofing.

[0003]

However, since the top surface of the coping is exposed to direct sunlight for a long period of time, the sealing material is liable to deteriorate over time. There is a problem in that it flows down into the inside and causes corrosion of the panel mounting members and the steel frame of the building frame. Therefore, the applicant has proposed a rain sash structure of a sash panel disclosed in Japanese Patent Application Laid-Open No. Hei 5-16965. It has to be fixed to the building frame via a bracket or the like, and there is a problem that work such as positioning and welding takes time and labor.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and aims to provide a rainfall structure for a kasagi panel which can prevent rainwater from entering the building frame from the kasagi panel portion and which can be easily constructed on site. Is what you do.

[0005]

According to the present invention, there is provided a shedding panel structure for a shelter panel comprising a plurality of shelter panels made of a metal plate arranged in a longitudinal direction, and a sealing material filled between end plates of adjacent shed panels. In the rain closing structure of the coping panel forming the joint for waterproofing, the longitudinal ends of the rain gutter disposed below the top joint between the end plates and having an upward opening width larger than the joint width of the top joint are formed. The rain gutter is supported by the support fitting in a state in which the rain gutter is inclined in the longitudinal direction by being hooked on a hook piece of a support fitting disposed inside the end plate and fixed to the coping panel. A drain pipe connected to a lower inclined end of the gutter is opened outward through a vertical joint between the end plates.

[0006]

According to the rainfall structure of the cap panel according to the present invention, after the cap panel is attached to the building frame (in the case of a carpet wall, after the frame panel and the frame together with the wall panel are attached to the building frame),
If a rain gutter is inserted from the gap between both end plates of the adjacent Kasagi panels and both ends are hooked on the hook pieces of the support fitting fixed to the Kasagi panel, the rain gutter is supported by the support fitting. Is supported at a position inclined downward in the longitudinal direction.

[0007] Since the support bracket is disposed inside the end plate of the coping panel, and does not protrude from the end of the coping panel, the carpet panel or a carton with the coping panel attached thereto.
When transporting or mounting the wall panel for the wall, it will not be damaged or damaged by being caught by other members or the human body, and will not interfere with the mounting work of the Kasagi panel or the curtain wall panel to the building frame. And never.

After the gutter is installed, the sealing material is filled between the both end plates to form joints. If the sealing material at the top joint breaks due to aged deterioration thereafter, the rainwater that has entered the joints is directed upward. It falls into the rain gutter opening to the outside, flows in the rain gutter according to the inclination, and flows out from the drainage pipe at the end.
