Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention connects joining legs formed upright on the upper part of adjacent metal roof plates back to back,
The present invention relates to a metal plate thatched roof structure in which strength is improved, workability is improved, and design is improved, and a fastener for a roof plate joint used for the structure.

[0002]

2. Description of the Related Art In recent years, a boltless folded plate having excellent workability and design has been widely used as a metal thatched roof of this kind. It is an excellent one that secures the watertightness by mechanically combining the parts. However, in the tightening part with the body, that is, the suspension part, the lower and upper halves are joined together via the lantern, so during strong winds, the deformation of the lantern or the deformation of the lower cavities (rotation) occurs. , The upper part of the roof tends to come off due to the displacement, etc. Therefore, it cannot be said that the wind pressure resistance is sufficient for the roof of a high-rise building. In addition, in a boltless folded plate, the left and right shapes are different, so the roofing direction has to be fixed. Furthermore, in the roofing work of boltless folded plates, when fixing the metal roof plate to the hangings, the half of the body is lifted from the roof part at the tip of the roof plate to perform the work. Therefore, it lacked safety and workability.

In order to improve the above points, a folded plate in which a cap material and a metal roofing material plate are fitted together to raise the roof has been developed, but in general, there is a gap in the folded plate body and the gap is covered. Since the cap material is covered so that it is difficult to obtain the structural strength caused by the folded plates being connected and integrated, the strength against the scattering of the folded plates due to strong wind is not sufficient, and even if it does not scatter. There was a gap between the folded plate body and the cap member due to deformation during strong wind rainfall, which led to water leakage. Also, when a large amount of snow was covered, a similar gap was generated, and there was a problem in water tightness.

[0004]

Accordingly, in the present invention, the strength durability against loads such as blowing up in strong wind, snow accumulation from the outside, weight of the worker, etc. is improved, and the direction of roofing is eliminated. At the same time, ensuring the watertightness of the joint and the safety of the work is a problem to be solved.

According to the present invention, a gap is not formed between the joining legs of the metal roof plate, and the joining legs serve as a reinforcing member for the cap member, and have strength durability against blow-up in strong wind and load from the outside. An object of the present invention is to provide a metal plate-roofed roof structure that can be improved and can be simplified in workability, and a fastener for a roof plate joint portion used for the structure.
