DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproofing technology for a roof or a wall of a building frame, and more particularly to a roof or a wall using a plate material such as a synthetic resin, metal, glass or natural stone as an exterior material. The present invention relates to a waterproof mounting structure of a panel plate material for constructing the plate material in a watertight manner when dressing.

[0001]

2. Description of the Related Art Conventionally, an exterior structure has been used in which a variety of plate materials such as an ALC plate, a slate plate, a glass plate, a metal plate, and a synthetic resin plate are abutted and juxtaposed to cover a roof surface or a wall surface of a building frame. Japanese Patent Application No. 10-101 discloses this type of structure.
No. 498. That is, as shown in FIG. 5, lower jaws 101, 101 are provided on both sides of the member, respectively, and a base frame member 100 forming a mounting portion 102 having a tapped groove formed in the center thereof, and a mounting bracket on a back surface. Fitting groove 10
5 and the upper jaw 10 facing the lower jaw 101
6, the sliding ends are fitted into the pair of holding frames 104, 104 and the fitting grooves 105, and the base ends are screwed into the tap grooves 103 with the base frame material 100 by tapping screws T. The frame structure including the fixing bracket 107 having the structure described above holds the peripheral edge of the panel plate material P such as glass, synthetic resin, or natural stone.

As a structure for maintaining the watertightness between the panel plate material P and the frame structure, a cover gasket 109 and a lower jaw 101 which form a winding portion from the front surface of the holding frame 104 to the lower side of the upper jaw 106 are fitted. Lower jaw gasket 10

The panel plate material is airtightly sandwiched between a lower gasket fitted and fixed to the lower jaw frame material and a cover gasket surrounded by the upper jaw frame material, and an inner edge of the cover gasket is screwed to the lower jaw frame material and the upper jaw frame material. Due to the structure, the edge of the holding frame material fastened to the base frame material is in close contact with the holding frame material, and the holding gasket that fits and integrates with the top surface of the holding frame material is fitted independently of the inner edge of the cover gasket. Hold and The cover gasket and pressing the gasket edge portion of the pressing gasket in the structure that covers the outer edge of the cover gasket, it is an Abstract that integrated composition by separate gripping and fitting structure relative to the frame member.

[0008] Further, the frame material of the edge holding portion of the cover gasket is constituted by a water-stop structure composed of a water-stop structure having a concave or a projecting cross-section extending in the longitudinal direction of the frame material, and water entering the contact portion by capillary action. The point is that the structure is such that the part structure is blocked.

Further, a lip edge extending along the outer surface is formed on a side edge of the presser gasket, and the lip edge is formed at a crossing position so as to be in close contact with a surface of the presser gasket which intersects, thereby preventing the presser gasket from being turned up by wind pressure. The gist of the present invention is that the structure is made as follows.
