Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. 1 and 2 show a first embodiment of the present invention, in which a waterproof sealing material 1 and a sealing material body 2 made of an elastic material such as foamed synthetic resin (e.g. foamed vinyl chloride, foamed urethane, etc.), foamed rubber, etc. , a viscous sealant 3 (e.g. sticky silicone-based, urethane-based, butyl-based, polysulfide-based resin, etc.), and a release paper 4 coated with a viscous sealant.
It consists of.

The sealing material main body 2 has a rectangular long bar shape in cross section, and its mounting surface 5 is provided with a groove 6 for filling the viscous sealing material over the entire length in the longitudinal direction. is filled. The mounting surface 5 and both end surfaces in the longitudinal direction of the sealing material body 2 are provided with:
A release paper 4 is attached to cover the exposed surface of the filled viscous sealant 3 to prevent drying, functional deterioration, and contamination of the surrounding area.

In the first embodiment, the waterproof sealing material 1
As illustrated in FIG. 2, when used for waterproofing the roof 9 of a shed extending on the outer wall surface 8 of the outer wall material 7 of a building, after peeling off the release paper 4 from the sealing material main body 2, On the outer wall surface 8 of the outer wall material 7 above the joint part of the roof 9,
The mounting surface 5 of the sealing material body 2 is brought into contact and temporarily fixed.
A sealing material presser 11 (wood, synthetic resin,
(long material made of stainless steel, aluminum alloy, etc.), drive the nail 12 into the exterior wall material 7 from the sealant presser 11, and attach the sealant main body 2 and drain plate 10 together with the sealant presser 11 to the exterior wall material 7. Can be fixed. At this time, the mounting surface 5 side of the sealing material body 2 is elastically deformed and comes into close contact with the uneven surface of the outer wall surface 8 , and at the same time, the viscous sealing material 3 in the groove 6 is
is compressed due to the elastic deformation of the groove 6 , and a part of it protrudes from the groove 6 , causing the outer wall surface 8 of the outer wall material 7 to become compressed.
It fits between the mounting surface 5 and the mounting surface 5, filling in the unevenness of the outer wall surface 8, and achieving a perfect adhesion state. The viscous sealing material 3 embedded in this manner is covered by the sealing material main body 2 , so that no exposed surface is provided, weather resistance is obtained, and the waterproof function can be maintained for many years. Further, since the draining plate 10 deforms the outer surface side of the sealing material main body 2 , the outer surface of the sealing material main body 2 and the sealing material presser 11 are in close contact, and rainwater does not go around inside the draining plate 10 . .
