Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a daylighting structure for a roof that requires fire protection in a factory, a warehouse, an arcade, or the like.

[0002]

[Prior Art]

 As for the lighting structure of roofs that require fire protection in factories, warehouses, arcades, etc., a structure with high fire resistance is required according to regulations such as Ministry of Construction Notification No. 101. Conventionally, the above-mentioned roof structure that requires fire protection is usually provided on the roof surface made of iron plate or slate. For the daylighting structure, a material that complies with Ministry of Construction Notification No. 101 is used as a daylighting plate and the daylight is projected above the roof surface. Main roof consisting of a flat roof plate as described in Japanese Utility Model Publication No. 58-50010, for example, to form a roof part for the roof, to combine a daylighting plate having the same shape as a corrugated plate of an iron plate or a slate plate, In some cases, the lighting plate is connected to the surface while maintaining a relatively flat outer shape that hardly bulges.

[0003]

[Problems to be solved by the device]

 However, the structure in which the roof for daylight projecting above the roof surface is not only bad in appearance, but also the rain is likely to be incomplete, and the connection structure to the ground roof plate itself is extremely complicated and requires a lot of man-hours. There is a problem that the weight also increases. Further, the method of laminating lighting plates of the same shape and the structure described in Japanese Utility Model Publication No. 5850010, which is connected while maintaining a relatively flat outer shape, has a better appearance than the structure protruding above the roof surface. In addition, it is completely rainproof and has excellent man-hours. However, in the cold season, dew condensation can easily occur, and water droplets can drop and contaminate stored items. Since it is made of polycarbonate, MMA, etc. and is flammable, it cannot be covered in a large area in terms of fireproofness due to the regulations of the Ministry of Construction Notification No. 101, etc.

[0004]

[Means for Solving the Problems] The problem is that a rectangular opening formed in a part of a ground roof plate that forms a main roof surface is provided with a daylight plate connected to the ground roof plate. This is solved by a roof daylighting structure characterized in that a netted glass plate is arranged at a lower portion and a non-fluid air layer is provided between the daylighting plate and the netted glass plate.

The material of the daylighting plate used for the roof daylighting structure of the present invention is FRP, polycarbonate, MMA, etc., and the shape thereof is an iron plate, or a slate corrugated plate, a folded corrugated plate, a goby corrugated plate, Any shape that can be used as a roofing material, such as a flat plate, is acceptable. It is easy to use a daylighting board with a shape that matches the shape of the flat roof board. The connection between the ground roof plate and the daylighting plate is similar to the normal roofing of the roofing tiles.For the ground roof plate in the upper position, the daylighting plate goes under and overlaps, and for the ground roof plate in the lower position. The lighting plate overlaps on it, and at the side position, the side edges of the lighting plate overlap and connect with the ground roof plate. Especially in the case of a goby board, a gap is created in the overlapping part, so use a sealing material to keep out rain. Further, as described in Japanese Utility Model Publication No. 58-50010, an accessory (for example, an aluminum member or the like) is attached and construction is performed with a sealing property.

The mesh glass plate used in the roof daylighting structure of the present invention is, for example, a flat plate of glass having a thickness of 5 to 10 mm and a lattice-shaped or hexagonal-shaped metal net inserted therein. The glass plate needs to have a fireproof property through which light can pass. In particular, by increasing the fireproofness against indoor fires, the lighting surface can be made wider. The meshed glass plate is provided below the daylighting plate with a gap. To attach a glass plate with nets, use a purlin or a rafter to attach a frame and place the glass plate on top of it to secure it. The mesh glass plate is easy to handle and convenient when used as a sash.

The non-fluid air layer provided between the daylighting plate and the netted glass plate of the roof of the present invention prevents dew condensation, and is formed by sealing the space between the daylighting plate and the netted glass plate. The sealing is performed by closing a gap between the purlin, the rafter and the frame and the daylighting plate or the mesh-filled glass plate with a door panel, packing or an amorphous sealing material.

The space between the daylighting plate and the meshed glass plate needs to be 2 cm or more at the narrowest point. If it is narrower than 2 cm, dew condensation may occur and it may fall into the room.

[0009]

[Action]

 Since the lighting structure of the roof of the present invention is connected to the ground roof surface while maintaining a relatively flat outer shape with almost no bulging of the lighting plate, it not only has a good appearance, but also has complete rain control. The glass plate with nets is placed below the daylighting plate with a space below it, and the non-fluid air layer provided between them acts as a heat insulating layer to prevent dew condensation in cold weather. Since the glass plate is placed, the fire resistance is significantly improved.

【Example】

 As shown in FIG. 1 and FIG. 2, the square iron frame 1 is attached to the purlin 3 by welding the square iron frame 1 to the opening 2 below the square opening 2 formed in a part of the iron plate folding roof. , The sash 5 is fitted to the right end surface of the square netted glass plate 4 in the iron frame 1 and between the iron frame 1 and the sash 5 and between the iron frame 1 and the valley portion 7 of the iron plate folding plate 6. The rubber packing 8 is inserted into each of the seals to seal them, and the triangular gap between the purlin 3 and the iron plate folding plate 6 and the FRP folding plate lighting plate 9 has a face plate 12 and a sealing material formed in the shape of the gap (see FIG. A non-fluid air layer (13) is provided between the daylighting plate 9 and the mesh-filled glass plate 4 by shielding with a not shown). The iron plate folding plate 6 and the daylighting plate 9 are joined to each other by a well-known method in which notches are cut in each other and engaged so that water does not enter inside. Fig. 3 shows an iron frame 1 to be mounted below an opening 2 provided on a folded plate roof made of iron plate according to the interval between purlins, and below the iron frame 1 is a square for receiving a meshed glass plate 4. Inner ledge 10 is provided inside, so that rubber packing 8 can be easily inserted in the gap between the upper plate and the outer frame of the iron frame 1 along the roof inclination direction and the valley 7 of the iron plate folding plate 6. An outer shelf 11 is provided. The vertical and horizontal dimensions of the iron frame are aligned with the purlin space and the space between the valleys of the iron plate stencil.

[Effects of the Invention] As described above, since the roof daylighting structure of the present invention is provided with the daylighting plate which is connected to the ground roof plate, the rain is completely protected and the appearance is good. Since there is a free-flowing air layer, there is no condensation even in cold weather, and since the lower layer facing indoors is equipped with a meshed glass plate, fire resistance is improved, so a wider lighting surface is required.
