DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for a metal sheet roof.

[0002]

2. Description of the Related Art In general, a metal sheet roof is formed by connecting metal roof sheets parallel to each other at a girder at the top of a building by seaming. In order to provide a daylighting section (lighting) on a roof, a daylighting roof panel made of a light-transmitting synthetic resin plate such as transparent, translucent or milky white is placed over the daylighting opening provided on the roof. I was

[0003] In such a conventional daylighting shingle, a hollow projection is fitted over the seam of the metal shingle on the top wall of the mountain part, and is provided over the entire length in the longitudinal direction of the shingle. Was.

[0004]

However, in this case, since the end of the lighting roof shingle is placed on the upper end of the metal roof shingle, especially above the water, rainwater can easily enter the gap between the two. The gap is filled with a sealing material such as foamed polyurethane in order to ensure watertightness, but since the flow path of the rainwater structurally reaches the inside of the roof for lighting, the sealing material is Due to the deterioration over time, there is a problem that water leakage occurs early and the watertightness is extremely poor.

Therefore, the applicant of the present invention previously provided a metal roof plate mounting bracket inserted under the water-side metal roof plate to the top wall at the water-side end of the light-transmitting synthetic resin plate. It is proposed that a notch of the required length be provided, and that a hollow protrusion be fitted over the spliced portion of the metal roof slab be provided on the top wall at the lower end of the water so as to protrude upward.

According to the previously proposed lighting roof shingle, it is possible to eliminate a structural defect in the lighting part of the conventional metal sheet roof, and to provide the metal sheet roof with a water-tight lighting part. It is excellent in workability because it can be formed, does not require special waterproofing treatment, and can be constructed in the same manner as a roofing operation using a metal shingle.

However, in the daylighting shingles proposed earlier,
A notch is provided on the top wall at the upper end of the water to allow the fittings to escape, and a hollow projection fitted over the seam of the metal roof plate projects upward at the top wall at the lower end of the water. In addition, since the roof shingles are so-called long ones, the molding requires a very large and special mold of the structure, and the equipment cost is high. There is a problem that manufacturing is not easy and implementation is difficult.

An object of the present invention is to solve the above problems,
The shape of the daylighting shingle itself should be simple, and the roof part of the underwater edge of the daylighting opening of the metal-plated roof has an upward bulge that is fitted over the spliced part of the metal roofing plate. By attaching another connecting member provided with a part, it is possible to form a daylighting part having excellent watertightness on a metal plate roof, and it is extremely easy to form the roofing plate itself for daylighting. Only small dies need to be used for molding, low equipment costs, no special waterproofing is required, and the same work as roofing work with metal shingles can be performed. It is an object of the present invention to provide a daylighting device which is excellent in practicality.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention has a lighting opening provided on a metal sheet roof in which parallel metal roof sheets are connected by seams. On the roof at the underwater edge of the daylighting opening, an upper bulging portion covering the end of the spliced portion of the metal roofing plate, and a bulging portion projecting into the opening from the lower edge of this portion. A required number of connecting members are covered, and the lighting opening has at least one flat valley connected to the flat valley of the metal roof plate, and left and right connecting portions connected to the connecting portions of adjacent roof plates on both left and right sides. A lighting roof shingle made of a light-transmitting synthetic resin plate having the above is covered, and the water-side ends of the top walls of the left and right connecting portions of the lighting roof shingle are inserted under the water-side metal roof shingle. The connecting member is placed on the underwater end of each top wall of the left and right connecting parts of the lighting roof shingle. A notch of a required length is provided in the length direction of the top wall to allow the upper bulging portion of the connecting member to escape, and the overhanging portion of each connecting member and the underwater end of each top wall of the lighting roof panel are provided. The gist is a daylighting device in a metal-plated roof in which a proximate part is interconnected.

It is to be noted that a lighting roof plate made of a light-transmitting synthetic resin plate which covers the lighting opening portion of the roof has at least two flat valley portions and at least one intermediate mountain portion between the two valley portions. In the case of having the left and right outer left and right connecting portions, the lighting connecting roof plate and the left and right connecting portions of the lighting roof plate and the upper end of the top wall of the intermediate mountain portion above the water above the metal roof plate above the water. A notch of a required length is provided in the length direction of the top wall to escape the inserted metal roofing plate mounting bracket,
A notch of a required length is provided at the underwater end of the top wall to escape an upper bulge of the connecting member when the connecting member is covered.

[0011]

In the above, a required number of connecting members are put on the roof portion of the underwater edge of the lighting opening on the metal sheet roof, and the metal roof plate is bulged by the upper bulging portion of the connecting member. After covering the end of the spliced part, the lighting opening is covered with a light-transmitting roof plate made of a light-transmitting synthetic resin plate. At this time, the water-side end of the lighting roof shingle is inserted under the metal roof shingle.

On the other hand, the underwater end of the daylighting roof panel is placed over the overhanging portion of the connecting member and overlapped, and the upper bulging portion of the connecting member is fitted into the notch of the underwater side end. In this state, the portion near the underwater end of the lighting roof shingle and the overhanging portion of the connecting member are connected to each other. Finally, a sealing material is applied to the side edge of the notch at the underwater end of the lighting roof panel and the edge of the upper bulging portion of the connecting member to seal the roof.

According to the above daylighting device, the shape of the transparent daylighting roof panel itself becomes simple, and the metal roofing panel is provided with a metal roofing panel at the roof part of the underwater edge of the daylighting opening of the metal sheet roof. By attaching another connecting member having an upper bulging portion to be fitted over the fly joint portion, it is possible to form a lighting portion (light) having perfect watertightness on the metal sheet roof.

Moreover, the molding of the daylighting roofing plate itself is extremely easy, and it is sufficient to use only a small mold for the molding of the connecting member. The equipment cost is low, and no special waterproof treatment is required. Since it is only necessary to carry out the same construction as the roofing work using metal shingles, the workability is excellent and the practicality is excellent.
