Abstract

PURPOSE:To thoroughly shut a gap between adjacent roof panels against rain water, and to dispense with site work for shutting off the rain water for the improvement of execution efficiency. CONSTITUTION:One bracket throating 4 is attached to the side of the under roofing material 3 of a sheathing roof board 1 along the side edge of the under roofing material 3, and an overlapping throating 6 is attached to the other end of the under roofing material 3.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof base structure for roof panels.

0002

2. Description of the Related Art Conventionally, waterproof tape has been pasted to cover gaps between adjacent roof panels during on-site construction.

0003

[Problems to be Solved by the Invention] As mentioned above, it is difficult to maintain sufficient water-tightness for a long period of time using waterproof tape alone, and since it requires on-site construction, it is difficult to maintain sufficient water-tightness for a long period of time using only waterproof tape. Often restricted and not efficient.

[0004] Accordingly, an object of the present invention is to provide a waterproof base structure for roof panels that can sufficiently water-tight the gaps between adjacent roof panels and eliminate the need for on-site construction to improve construction efficiency.

[0005]

[Means for Solving the Problems] A feature of the waterproof base structure of a roof panel according to the present invention is that a single receiving drain 4 is fixed to one side of the underlayment material 3 on the roof board 2 along its side edge. , where an overlap drainer 6 is fixed to the other side of the underlayment material 3.

[0006]

[Function] At the construction site, if both roof panels are installed in a row so that the overlapping flashing of the other roof panel overlaps the receiving flashing of one roof panel, the
Waterproofing treatment is also applied to the roof material base.

[0007]

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Reference numeral 1 indicates a roof panel. 2 is roof panel 1
The roofing board 2 is on the upper surface, and an underlayment material 3 such as a roofing is laid on the roofing board 2.

A long receiving drain 4 is placed along one side edge of the base roofing material 3, and the receiving drain 4 is attached to the base roofing material 3 with waterproof tape 5. In addition, the drainer 4
may be attached to the lower side of the underlayment material 3.

A long overlapping flashing 6 is placed along the other side edge of the base roofing material 3, and the overlap flashing 6 is attached to the base roofing material 3 with waterproof tape 5. ing.

By the way, to explain the above-mentioned double drainers 4 and 6 in more detail, the overlap drainer 6 is made of a metal plate or a waterproof fabric sheet with some shape retention. , a horizontal portion 6A placed on the underlayment material 3, a rising portion 6B from the horizontal portion 6A, an overlap portion 6C bent horizontally from the rising portion 6B, and the overlap. It consists of a waterproof packing 7 made of foam material or the like attached to the lower surface of the portion 6C. Note that the waterproof packing 7 does not necessarily have to be provided with the rising portion 6B.

On the other hand, like the overlap drainer 6, the receiving drainer 4 is made of a metal plate or a waterproof fabric sheet with some shape retention, and is attached to the side edge of the underlayment material 3. It consists of a folded part 4A along which the horizontal part 4B has a width to which the waterproof tape 5 is attached and a width on which the waterproof packing 7 is seated. In addition, both gutters 4 and 6 may be attached to the roof board 2 by nailing them and then pasting waterproof tape 5 on them. Further, instead of the folded portion 4A, a rod-shaped body having a rectangular cross section may be adhered.

[0013] Therefore, at the construction site, the roof panel 1
. Waterproofing treatment is applied.

[0014]

Effects of the Invention As can be understood from the above explanation, according to the present invention, a roof panel can be installed by simply joining adjacent roof panels together, receiving the waterproof packing of an overlap drainer, and seating it on the drainer. Since the gaps between the panels can be sufficiently water-tightened, it becomes possible to omit waterproofing of the roofing material at the roof panel joints at the construction site, and construction efficiency can be significantly improved.
