Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, an exterior structure has been used in which various plate materials such as an ALC plate, a slate plate, a glass plate, a metal plate and a synthetic resin plate are abutted side by side to cover a roof surface and a wall surface of a building frame. As a structure of this kind, a structure as shown in FIG. 6 is used, and the lower jaw 10 is provided on each side of the member.
1, 101 is provided and tap groove 10 is provided at the center thereof.
3. Base frame material 100 that constitutes the mounting portion 102 in which 3 is formed
And a pair of presser frames 104, 104 each having a mounting bracket fitting groove 105 provided on the rear surface and an upper jaw 106 facing the lower jaw 101, and the fitting groove 1
No. 05 is made of glass, synthetic resin, or natural stone according to a frame structure including a fixed bracket 107 having a structure in which a sliding end is fitted and a base end is screwed and fastened to a tap groove 103 with respect to a base frame member 100 by a tapping screw T. It has a structure for holding the peripheral edge of the panel plate material P such as.

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. Combined lower jaw gasket 11
The panel plate material P is sandwiched between 0 and the groove-filling gasket 112 is fitted between the cover gaskets 109, 109 provided on the holding frame 104 and facing back.

That is, in the above-mentioned conventional structure, a first watertight structure is provided between the cover gasket 109 provided on the holding frame 104 and the surface of the panel plate P, and a second watertight structure is provided between the cover gasket 109 and the groove filling gasket 112. The structure of the structure prevents the entry of rainwater and the like due to the close contact between the members.

[0005]

However, in the conventional watertight structure described above, the lip 112a of the groove filling gasket 112 is fitted between the engaging edges 109a and 109a of the cover gasket 109 engaged with the engaging edge 104a of the holding frame 104. Since the structure is such that the cover gasket 109 and the groove filling gasket 112 have a small fitting force with respect to the frame structure.

That is, when the external pressure becomes lower than the internal pressure of the seal portion due to the influence of wind or the like, the groove filling gasket 11 due to the wind
Combined with the curling action of 2, the groove filling gasket 112
Is the engaging edge 109a of both cover gaskets 109,109
There was a fatal problem that the waterproof structure of the seal part did not function at all because it was pulled out from the space.

The present invention has been made in view of the above problems, and in a panel mounting structure in which a plate material is sandwiched between frame structures composed vertically and horizontally, and is expanded and expanded in the plane direction, pressure is applied to the internal and external pressures of the panel by wind. It is an object of the present invention to provide a waterproof mounting structure for a panel plate material having a new structure in which the gasket of the seal portion does not pull out and separate even if a difference occurs and the sealing performance can be maintained for many years.

[0025]

As described above, in the waterproof mounting structure for a panel plate material according to the present invention, the panel plate material is sandwiched between the lower jaw gasket attached to the lower jaw frame member and the cover gasket surrounded by the upper jaw frame member, and tapping screws are provided. In the mounting structure of the panel plate material that is fastened and held to the frame material, it is stable because the cover gasket is fitted into the holding groove with the frame seat independently of the holding gasket or is sandwiched between the frame materials. It is possible to retain it properly and to prevent accidents such as dropping due to the action of wind pressure.

Further, since the water-blocking ridges of the holding frame material, especially the inner edge portion of the cover gasket, are pressed and fixed, the intruding water is blocked by the capillary phenomenon, and the watertightness can be improved. A lip edge is formed on the pressing gasket that is fitted and fixed to the pressing frame material so that the pressing gasket comes into close contact with the surface of the adjacent pressing gasket at the crossing portion, and roll-up due to wind pressure is prevented. Combined with the above, it has a feature that the sealing performance of the portion can be maintained at a high level, and the effect obtained by implementing the present invention is extremely large.
