BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roofing method using a roof plate.

[0002]

2. Description of the Related Art Conventionally, a roof plate made of a metal plate used for a so-called cylindrical thatched roof has a flat valley portion, an arcuate left rising portion connected to the left side edge portion thereof, and an arc shape connected to the right side edge portion thereof. It is equipped with a right rising part, whereas
Tight frames are placed at the required locations on the roof base material of the building, and the roof plate fixing brackets with a special shape are fixed to the upper protrusions provided at predetermined intervals on the tight frames with bolts and nuts, and The arc-shaped left rising portion and the arc-shaped right rising portion which should be connected to each other of the adjacent roof plates are respectively covered on the upward protruding portions of the tight frame,
Tighten the upper edge of the left rising part and the upper edge of the right rising part together with the upper end of the specially shaped fixing bracket so that the arc-shaped left rising part and the arc-shaped right rising part of the adjacent roof plates are tightened. Were bound to each other.

[0003]

However, in such a conventional roofing method using a roof plate , in order to fix the roof plate , a special shape other than the tight frame having the upward projecting portion, the bolt and the nut is used. Not only the number of parts required was large, but the roofing work was very troublesome and time-consuming, and the roof construction cost was high. Further, the roof plate is connected to the tight frame via a specially shaped fixing metal fitting, and the roof plate and the tight frame are not directly connected to each other, so that the roof plate is not sufficiently attached, for example, a typhoon or the like. In the case of a large wind, there was a problem that the roof plate and the upper end of the fixing bracket were loosely connected to each other by the negative pressure due to the wind pressure or the pressure difference, and the roof plate might come off and blow off. . Furthermore, for example, if heavy rain continues for many days, rainwater is filled on the top surface of the roof of the thatched roof, and rainwater that has infiltrated from the connection between the roofboards has infiltrated the inside of the roofboard due to the so-called capillary phenomenon. There is a problem that this rainwater drops into the interior of the building.

An object of the present invention is to eliminate the need for a conventional fixing bracket having a special shape for fixing a roof plate, to reduce the number of parts during roof construction, and to easily perform roofing work. It does not take time and labor, the roof construction cost is low, and the roof plate and the tight frame can be directly connected, and the roof plate mounting strength is sufficiently large.
For example, even in the case of a large wind such as a typhoon, there is no risk that the roof plate will come off and blow off, and the roof plate connection is excellent in airtightness, which can reliably prevent rainwater from entering and is durable. In addition, it is possible to guide rainwater droplets that have soaked into the connection part of the roof plate at the time of heavy rain to the outside of the eaves of the roof, and there is no risk of these water droplets falling inside the building. It is to provide a roofing method using a roof plate.
