Description

The present invention relates to a corrugated slate fireproof daylighting device used as a roofing material or an outer wall material of a warehouse, a factory, a gymnasium or the like.

Conventionally, it is corrugated because it is excellent in fire resistance, water resistance, durability, and low cost as a roofing material or exterior wall material of many public facilities including large buildings such as factories, warehouses, gymnasiums, arcades in shopping streets, etc. A slate plate is widely used, and a daylighting window portion made of netted wave-type glass for light removal is attached between the roof and the outer wall of the corrugated slate.

On the other hand, the corrugated slate plate and the meshed wave type glass plate have different corrugated shapes depending on applications, and so-called small wave type, large wave type, and extra large wave type slate plates are used. In particular, large wave and extra large wave type slate plates are widely used as roof boards for large factories and warehouses, and small wave type and large wave type slate plates are used for outer walls.

The above-mentioned net-in type glass sheet is widely used because it has fire resistance as defined by the Building Standards Act as a roofing material or an outer wall material. However, the corrugated slate plate and the meshed wave type glass plate are deteriorated with age after a considerable number of years after construction, and the slate plate and the glass plate become brittle and are easily damaged by an external impact. Therefore, in order to prevent damage due to aging, it is known to reinforce by coating the surface of the corrugated slate plate, or by covering the surface with a cover (see, for example, Patent Documents 1 and 2). .

However, it is necessary to repair the roof and the outer wall surface covered with the corrugated slate plate or the meshed wave-type glass plate because a part of the roof or the outer wall surface is damaged or cracked, thereby causing rain leakage. When a considerable number of years have passed since construction, there may be no inventory of the same type of corrugated slate plate or netted corrugated glass plate as a repair material, or production may have been discontinued. It may be difficult to obtain a mesh-type glass plate.

In addition, the netted wave-type glass plate for daylighting attached to a part of the roof or the outer wall is less in demand with the passage of time because the application is special, and the number of production is also decreasing. For this reason, there are many cases where there is no stock when it is needed, and in particular, the production of the oversized wave-type mesh-in type glass plate has already been discontinued.

Since it is difficult to obtain a net-in type glass plate, it is difficult to attach a daylighting window using the net-in type glass plate to the roof. Therefore, attaching the lighting window (top light) protruded from the surface of the roof is performed. However, since the daylighting window is formed in a horizontally long shape, rainwater on the upper side of the water is blocked and hardly flows, and when rainwater accumulates, it tends to cause rain leakage. For this reason, it is necessary to install a sealing member for preventing rain leakage on the water side of the daylighting window or to increase the distance between the daylighting windows so that the rainwater flows easily. is there.

A corrugated resin plate made of a synthetic resin material that can be mass-produced at low cost is used in a place where the corrugated slate plate or the meshed glass plate breaks and needs to be repaired, or a lighting window provided on the roof or the outer wall. Therefore, it can be changed easily. However, since the corrugated resin plate does not have fire resistance, it has a problem that it cannot clear the fire resistance prescribed in the Building Standard Law.
