Another object of the present invention is to provide a mounting material having a structure that prevents rainwater from entering the mounting material and improves rain performance.

And in order to solve the said subject, the waterproof layer edge part attachment material which concerns on this invention is equipped with the base material fixed to a building frame roof part , and the cover material attached to this base material via a joint bracket, and is waterproof. In the waterproof layer end mounting material that holds the end of the layer, the base material is composed of a pair of upper and lower horizontal portions, a rising portion that connects the vertical portions, and a drooping portion that extends from the rising portion, and the joint bracket Consists of a pair of front and rear hanging parts and a horizontal part connecting them, and the cover material comprises a pair of front and rear hanging parts and a horizontal part connecting them. Furthermore, it can comprise so that the protrusion which protrudes toward the member adjacent to at least 1 of the said base material, a joint bracket, and a cover material may be provided. Further, the protrusions, wherein the on the inner surface of the front vertical lower portion of the joint bracket is formed either at least on the inner surface of the horizontal portion can be configured to abut the base member. Further, the projection may be formed on at least one of the inner surfaces of the front and rear hanging parts of the cover material and contact the joint bracket. Furthermore, the cover material can be configured by combining two members divided at the horizontal portion. Furthermore, the base material , the joint bracket, and the cover material can be fixed with screws.

According to the present invention, since the rising portion of the base material is formed at a substantially right angle, it is easy to process the base material having an arc shape in plan view used for the R portion of the roof. In addition, since the waterproof layer end can be raised at a right angle along the rising portion of the base material , rainwater does not enter inside due to the wind, and the rain finish is excellent. Further, since the assembly can be performed simply by using the elasticity of each member to bend and latch appropriately, the workability is extremely excellent. Further, since each member is brought into contact with the projection, rattling due to wind or the like can be prevented after assembly. Further, when into contact with the base material to form a protrusion on the inner surface of the inner surface on the horizontal portion of the front vertical lower portion of the joint bracket, rattling between the base material and the joint bracket it can be prevented. Further, when into contact with the joint bracket formed on the inner surface of the front and rear hanging parts of the cover member projections, rattling between the joint bracket and the cover member can be prevented. Further, when the cover member is configured by joining two members divided in the horizontal portion, the processing of the R portion is facilitated. If the base material , the joint bracket, and the cover material are further fixed with screws, the assembly becomes stronger and rattling is more reliably prevented.

Thus, unlike the conventional example, the end of the waterproof layer 51 rises substantially vertically and does not become a slope, so that there is very little possibility that rainwater will enter the mounting material 1 and the rain finish is good. In addition, when the joint bracket 15 is attached to the base material 2 , the joint bracket 15 is attached at an appropriate interval on the base material 2 , and is disposed at a position corresponding to the joint of the adjacent cover material 35, so that rainwater is temporarily provided from the joint of the cover material 35. I enter is because is discharged also the rainwater is received by the joint bracket 15, is not flowing through the joint of the cover member 35 to such coking 53.

FIG. 5 is a cross-sectional view showing the waterproof layer end attaching member 61 used for the R portion of the roof , but the basic structure is the same as the waterproof layer attaching member 1 used for the above-mentioned straight portion, and is different therefrom. Only the part is explained.

The base material 62 includes a base main body 63 and a floor plate 67 attached below the base main body 63. The difference between the base body 63 and the base material 2 is that the lower horizontal portion 64 is shorter than the lower horizontal portion 3 of the previous base material 2 and is higher than the rising portion 65 by the thickness of the floor plate 67. It is provided in a position, and its hanging portion 66 is long. Thus the height position of the upper horizontal portion 63a has no trouble no for mounting same der because the upper horizontal portion 7 of the base member 2 arranged in a linear portion, a joint bracket 15. The floor plate 67 has a long and narrow plate shape, and is longer than the lower horizontal portion 64, and its front end is abutted against the inner surface of the hanging portion 66 of the base body 63 with respect to the base body 63 bent into an arc shape. In this state, a plurality of them are arranged radially at appropriate intervals and fixed to the base body 63 by brazing. The floor plate 67 is fixed to the roof portion H.

The joint bracket 15 is the same as that used for the previous straight portion. The cover material 71 is configured by brazing two members, a cover main body 72 and a rear member 73, which are obtained by dividing the cover material 35 into two at the position of the upper end of the shoulder portion 37c of the horizontal portion 37 as shown in the figure. is doing. The cross-sectional shape of the cover material 71 is substantially the same as the shape of the cover material 35 described above, but there is no portion corresponding to the hook 47 and the projection 49 formed on the rear hanging portion 41. In this example, as shown in the figure, the members are hooked together, and the cover member 71, the joint bracket 15 and the base member 62 are coupled together using a screw 75 with a water stop washer 76. As a result, the three members are more firmly coupled, and rattling is more reliably prevented.
