Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a waterproof sheet end holding fitting used when waterproofing a rooftop using a waterproof sheet.

<Prior Art and Problems> Conventionally, rubber or plastic sheet waterproofing materials (hereinafter referred to as waterproof sheets) have been widely used for rooftop waterproofing such as flat roofs. When waterproof sheets are used for rooftop waterproofing, there are always problems with adhesion of the joints between the sheets and how to fit the rising parts. The joints between the sheets have been solved to a large extent through research on adhesives, combined use of welding methods, and construction methods such as overlapping, but there are still many unresolved issues regarding how to fit the rising parts.

FIGS. 5 to 7 are examples of conventional ways of storing the rising portion. Fig. 5 shows an example in which a draining part D is integrally constructed at the tip of the rising part of a flat roof frame A, and a waterproof sheet B is constructed along the frame A, and its leading edge is attached to an aluminum sheet end holding metal fitting 62. and is fixed to the frame A with screws 64. In this case, elastic sealing materials 63 and 67 are filled inside the presser fitting 62 and directly below the draining portion D to prevent rainwater from entering through the gap between the frame A and the metal fitting 62 or through screw holes.

In the case of this construction method, the drainage part D, which is integrally formed with the concrete frame, effectively prevents rainwater from entering, and the elastic concrete materials 63 and 67 maintain more perfect watertightness. The disadvantage was that filling the material was extremely complicated and time-consuming. In particular, filling the elastic sealing material 67 directly below the draining portion often requires bending over, which is often painful work, and improvements have been sought.

Figure 6 shows how to store the rising part without the draining part D, and the waterproof sheet B is constructed along the frame A.
The tip is held down with a holding fitting 62 similar to that shown in FIG.
Fix it to the body with screws 64. Next, a draining metal fitting 65 is used to cover the upper part of the presser metal fitting and fixed with screws 66. In this case as well, as in Figure 5,
Elastic sealing materials 63 and 67 are filled inside the presser fitting and directly under the draining fitting. In the case of Fig. 6, a draining fitting is required, and filling with elastic sealant is also essential, making it more complicated than Fig. 5.
The drawback is that the construction cost is high, and improvements have been sought.

Fig. 7 shows the conventional method of installing the veranda part of a wooden house, with a concrete panel 52 installed on the veranda base 51, and a concrete panel 53 in the same way for the five standing parts, and a waterproof sheet B pasted on the top surface. Leave the rising end attached.

A draining fitting 55 is attached to the upper part of the terminal, and fixed with a screw plug 57 and a fixing screw 56. Asphalt felt 54 is laid on the upper part of the concrete panel 53, mortar 60 is cast through the lath 59, and a cap 6 is placed on the top of the rising part 50.
Place 1 and finish.

In the case of the construction method shown in FIG. 7, there is no use of the presser fitting 62 shown in FIGS. 5 and 6, and the key to maintaining watertightness is concentrated only on filling the elastic sealant 58, making it an extremely dangerous construction method. Ta.
