Description

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

Traditionally, it is a wave type because it is excellent in fire resistance, water resistance and durability as a roofing material or outer wall material for many public facilities such as large buildings such as factories, warehouses and gymnasiums, arcades in shopping malls, etc. A slate plate is widely used, and a window with a light-entering light-incident type glass is attached between the corrugated slate-covered roof and the outer wall.

On the other hand, the wave-like slate plate and the meshed wave-like glass plate are different in wave shape depending on the application, and so-called small wave, large wave, and oversized wave slate plates are used. In particular, large wave type and oversized wave type slate boards are widely used as roof sheets of large factories and warehouses, and small wave type and large wave type slate boards are used for outer walls.

The above-mentioned reticulated wave-type glass sheet is widely used because it has the fire resistance specified by the Building Standard Law as a roof material or an outer wall material. However, the wave-like slate plate and the net-like wave-like glass plate deteriorate with time after a considerable number of years after construction, and the slate plate and the glass plate become brittle and easily damaged by external impact. Therefore, in order to prevent damage due to deterioration, it is known that the surface of a corrugated slate plate is painted and reinforced, or the surface is covered with a cover and reinforced (see, for example, Patent Documents 1 and 2). .

However, it is necessary to repair the roof and the outer wall surface that have been ground with the above-mentioned corrugated slate plate or mesh-type corrugated glass plate, since it may cause rain leakage if a part is broken or cracked. When a considerable number of years have passed after construction, there may be no stock of the same type of corrugated slate plate or meshed glass plate as a repair material, or production may have already been discontinued. It may be difficult to obtain a reticulated glass sheet.

In addition, due to the special purpose of the light-entering light-entering glass plate attached to the roof and a part of the outer wall, the demand is low with the passage of years, and the number of production decreases. Therefore, there are many cases where there is no stock at the time of need, and in particular, oversized wave-type netted glass sheets have already been discontinued.

It is difficult to mount a daylighting window using a net incident glass sheet on the roof because the net incident glass sheet is difficult to obtain. Therefore, it has been practiced to mount a daylighting window (top light) projecting from the surface of the roof. However, since this light-receiving window is formed horizontally long, the rainwater on the upper side of the water is blocked and difficult to flow, and when the rainwater is accumulated, it tends to be a cause of rain leakage. Therefore, it is necessary to attach a seal member for preventing leaks to the water upper side of the daylighting window or to make it easy for rainwater to flow by opening the spacing of the daylighting window. The construction is complicated and time consuming and very uneconomical is there.

Use a corrugated resin plate made of a synthetic resin material which can be mass-produced inexpensively as a part where the corrugated slate plate or the meshed corrugated glass plate is broken and needs repair, or a daylighting window provided on a roof or an outer wall In some cases, you can easily change your mind. However, since the corrugated resin sheet does not have fire resistance, it has a problem that it can not clear the fire resistance specified in the Building Standard Act.

After the fireproof frame 2 is mounted in the vertical and horizontal directions of the repaired portion to form the light collecting frame S, the corrugated resin plate 5 is mounted on the surface. The corrugated resin plate 5 is attached to the lower end of the corrugated resin plate 5 by placing the upper end (the ridge side) under the eaves side end of the corrugated slat plate 65 located at the repair point. Side is attached and installed on the upper surface of the corrugated slate plate 65 'located on the eaves side of the repair point. Thus, it is possible to prevent the leak without filling the sealant for preventing the leak.

Furthermore, when reworking fireproof lighting apparatus 1, fireproof lighting apparatus 1 with fireproof frame 2 vertically and horizontally using existing protagonist Y located at the repair site without assembling a construction scaffold on the roof The construction cost is cheap and economical because it can be easily connected to one another. In addition, the fireproof light collecting device 1 has a double structure of the fireproof frame 2 and the wave-shaped resin plate 5, and the outer peripheral surface of the light collecting frame S is further surrounded by vertical and horizontal fireproof plates 67 and 69 to provide air inside. The layer has a heat insulating effect, and in the event of a fire, it can prevent the flame from entering the fireproof light-collecting device 1 and also has resistance to external impacts.

In the case where the fireproof daylighting device 1 is attached to the repair location made on the outer wall surface M of a building, the existing trunk rim N provided with a plurality of fireproof frames 2 conforming to the size of the predetermined repair location on the outer wall surface The outer wall surface can be easily repaired by attaching the wave-shaped resin plate 5 which is a synthetic resin material formed in the same wave shape as the wave-shaped slate 65 mounted on the outer wall surface M to form the light collection frame S. it can. The process of attaching the fireproof daylighting device 1 to the outer wall surface M is the same as the case where the fireproof daylighting device 1 is attached to the roof, and therefore the description thereof is omitted.
