The present invention has taken the following technical means. That is, the present invention relates to a roof waterproof sheet which is formed of a long sheet main body having flexibility and watertightness, which is extended along a joint portion or an edge portion of a field board, wherein the waterproof sheet is a sheet. It is characterized in that bent portions that can be bent along the longitudinal direction of the main body are provided at the widthwise central portion and both end portions of the seat main body.

[0006]

[Function] By adopting any one of the three bent portions provided at the center and both ends in the width direction of the seat body 1, one kind of waterproofing as shown in, for example, FIGS. Sheets can be applied to various parts of the roof.

[0007]

An embodiment of the present invention will be described in detail below with reference to the drawings. As shown in FIG. 1 and FIG. 2, the waterproof sheet according to the present embodiment is composed of a long sheet body 1 having flexibility and watertightness such as polypropylene. It is equipped with a large number of drainage ridges 2 parallel to the longitudinal direction of 1. The draining ridges 2 have a substantially isosceles triangular shape in cross section, and are arranged in parallel in the width direction of the seat body 1 at regular intervals, whereby trapezoidal draining grooves 3 having a trapezoidal cross section are formed between the draining ridges 2. Has been done.

The waterproof sheet according to this embodiment is a sheet body.
Bent portions 4 and 5 that can be bent along the longitudinal direction of 1 are provided at the center and both ends in the width direction of the seat body 1. Of these, the first bent portion 4 located in the center portion in the width direction has a substantially corrugated cross-section consisting of two crests that curve toward the front side of the seat body 1 and one trough that curves toward the back side. The second bent portions 5 located at both ends in the width direction consist of only one ridge portion that curves toward the front surface side of the seat body 1, and any of the first bent portions 4 and 5 extends along the longitudinal direction of the seat body 1. It has been extended.

Therefore, the seat body 1 has the first bent portion.
In Fig. 4, both the mountain fold side and the valley fold side are easily bent when viewed from the surface of the seat body 1, and the second bent portion
It is easy to bend to the mountain fold side at 5. Also,
On the front surface side of the seat body 1, a nailing portion 6 having a substantially trapezoidal cross section is extended along the longitudinal direction of the seat body 1, and in this embodiment, the nailing portion 6 is formed by the seat body. 1
Widthwise both edges and the first bent part 4 left and right both sides in total 4
It is provided in various places.

Note that, as shown in FIG. 2, the waterproof sheet is wound around a roll 7 during its transportation, and is carried out by straightening it after being carried on the roof.
FIG. 3 shows a case where the above-mentioned waterproof sheet is applied to the fluff portion of the roof. In the figure, a waterproof paper 9 made of asphalt roofing, etc. is laid on the upper surface of the base plate 8 which is the base of the roof, and the roof tile 10 is roofed on the waterproof paper 9 and the gable part of the base plate 8 is provided. A gable plate 11 is fixed to the lower surface. The waterproof sheet is interposed between the waterproof paper 9 and the roof tile 10 with the drainage ridge 2 facing upward, and the second bent portion 5
By fixing the widthwise end of the sheet main body 1 bent downward through the to the baffle plate 11 at the nailing portion 6, the sheet main body 1 is extended along the gable portion of the base plate 8.

When the roof fluff portion is rain-protected by the waterproof sheet as described above, complicated sheet metal working is not required, so that the construction can be facilitated. Figure 4
Shows the case where the above-mentioned waterproof sheet is applied to the roof fluff portion as in FIG. 3, but the difference from the case of FIG. 3 is that the sheet body 1 is attached to the first bent portion 4 as shown in FIG. The sheet body 1 is cut in half along the cutting line C, and the sheet body 1 cut in half is interposed between the waterproof paper 9 and the roof tile 10. Therefore, in this case, the length of the waterproof sheet used for the fluff portion having the same length is half, and there is an advantage that the material cost can be significantly reduced.

On the other hand, FIG. 5 shows a case where the above-mentioned waterproof sheet is applied to a corner ridge of a roof. In this case, the waterproof sheet is mountain-folded at the first bent portion 4 and is nailed on the waterproof paper 9 so that the first bent portion 4 is along the building core 12, and the roof tile 10 is placed on the waterproof sheet. Is tiled. In addition, 13 is a ridge corner sheet metal fixed on the roof tile 10.

Further, FIG. 6 shows a case where the above-mentioned waterproof sheet is applied to a valley portion of a roof, and the waterproof sheet has a first bent portion 4
At the same time, it is folded in a valley and is nailed to the waterproof paper 9 so that the first bent portion 4 is along the valley 14, and the valley gutter 15 is fixed on the central part of the waterproof sheet, and the roof tile.
Tens are constructed so as to wrap around both ends of the trough 15.

Further, FIG. 7 shows a case where the above-mentioned waterproof sheet is applied to the wall contact portion (on the flow wall) of the roof. In this case, the waterproof sheet is valley-folded at a substantially right angle at the first bent portion 4, and the horizontal half of the sheet main body 1 is nailed to the base plate 8 and the vertical half is nailed to the wall substrate 16 to form a waterproof paper.
It is interposed between the roof tile 10, the roof tile 10 and the outer wall panel 17. In addition, 18 is a rain guard, and it is a base plate through Kasagi 19.
It is fixed at 8. Further, it goes without saying that the waterproof sheet can also be used on the side wall of the roof ridge.

The present invention is not limited to the above-mentioned embodiment, and for example, the cross-sectional shape of the bent portions 4 and 5 may be not only the curved shape described above but also a serrated bellows shape or the like.
Any shape may be used as long as it can be bent along its longitudinal direction.

[0016]

As described above, according to the present invention,
Since the waterproof sheet is provided with a bendable portion that can be bent along the longitudinal direction of the sheet body at the widthwise central portion and both ends of the sheet body, the end portion side bend portion (second bend portion) in the fluff portion. By selecting the bent portion according to the construction site, such as adopting, it is possible to perform waterproof construction on various parts of the roof with one type of waterproof sheet, and thus facilitate inventory management during roof construction.

If the sheet body is cut at the central bent portion (first bent portion), the length of use of the waterproof sheet can be halved depending on the construction site, and the material cost can be reduced.
