Description

[Detailed description of the invention] [Technical field] This invention relates to a side door that is attached between a roof tile and a ridge tile or at the end of a ridge tile.

[Background technology]

Conventionally, a door made of a foam such as a foamed synthetic resin has been attached between the top surface of a corrugated roof material and a ridge tile, but this method has had the disadvantage of being inferior in terms of fire protection.

[Purpose of invention]

The present invention has been made in view of the above points, and an object of the present invention is to provide a surface door that can be elastically interposed and installed without any gaps, and that can improve fire protection.

[Disclosure of invention]

The mendoor of the present invention is constructed by covering the entire exposed side of the mendoor main body 1 made of high foam with a flexible fireproof surface layer 2 with a low burning rate. This solves the drawbacks of the conventional example.

The present invention will be explained in detail below with reference to Examples. The side door A is composed of a side door body 1 made of a highly foamed material and a fireproof surface layer 2 laminated on the entire exposed side of the side door body 1. The door main body 1 is made of a highly foamed material made of highly foamed synthetic resin such as highly foamed polyethylene, and the fireproof surface layer 2 is made of a non-foamed synthetic resin sheet such as vinyl chloride or a low foamed synthetic resin layer. , is flexible and has a low burning rate.
This low burning rate means that the combustion test
Refers to those with low combustion speed according to MVSS-302 or ASTM-1692. Further, the door main body 1 and the fireproof surface layer 2 may be made of the same synthetic resin or different synthetic resins. The above-mentioned side door A is installed between the ridge tile 3 and the corrugated roofing material 4.
is a long and narrow object, and its lower part forms a wavy portion 5 along the top surface of the corrugated roofing material 4. Next, the operation of constructing a roof using the side door A constructed as described above will be explained. A field board 7 and roofing 8 are laid on the rafters 6 that are long in the direction of the eaves, a ridge ventilation opening 9 is formed in the ridge part to communicate with the attic, and drainage boards 12 are installed on both sides of the ridge ventilation opening 9. A corrugated roofing material 4 is covered over the entire surface of the roofing 8. Next, on both sides of the ridge, side doors A are installed on the roofing material 4 in the direction of the main building.
, place the wavy part 5 of the door A so that it fits on the top surface of the roof material 4, place the ridge sill 10 on the top surface of the door A, and insert the ridge sill 10 from above the ridge sill 10 through the door A. Field board 7
When nails 11 are driven in to fix the ridge sill 10 and the side door A, the side door A is compressed so that its lower surface comes into close contact with the upper surface of the roofing material 4 and its upper surface comes into close contact with the ridge sill 10. Next, a rain cutter board 13 is installed between the ridge ends 10, and an arch-shaped support fitting 14 is installed on the rain cutter board 13 and fixed to the ridge board 10 with nails 16. The rain cutting board 13 is provided with ventilation holes 15. Next, the ridge tile 3 is fitted so as to cross the arch-shaped support fittings 14, and the ridge tile 3 is attached to the support fittings 14 with the mounting screws 17, and the tile ventilation opening 18 provided in the ridge tile 3 is fitted with eyes for preventing birds and rats. plate 19
Install. Further, FIG. 5 shows another embodiment of the side door A, in which the side door A is formed in a shape that matches the opening at the gable side end of the ridge tile 3. This side door A fits into the opening at the gable side end of the ridge tile 3, and the fixing member 20 is inserted from the surface.
Fix it with nails 21.

[Effect of idea]

As mentioned above, the main door of the present invention is made of a highly foamed material, so it is elastic and can be installed without any gaps, and the exposed side of the main door can be burned. Because it is covered with a fireproof surface layer with a low velocity, even if the main body of the door is made of high foam, the exposed side is difficult to burn and can improve fire protection.Moreover, since the fireproof surface layer has flexibility, the surface The door body can be elastically deformed together with the door body, making use of the characteristics that the door body is made of high foam and can be installed without any gaps.Furthermore, a fireproof surface layer is provided on the entire exposed side of the door body. Regardless of the degree of deformation of the door, the entire surface of the exposed side can always be covered with a fireproof surface layer, thereby improving fireproofing performance.
