The waterproof fixture of the present invention is formed by winding an adhesive tape around a shaft near the head and inserting the adhesive tape into the insertion hole, and following the shape of the insertion hole as the adhesive tape moves between layers. since the axially portion and a wrapped body Ru fills a gap between the insertion hole, the wrapped member simultaneously inserted to be fixed to the fastener insertion hole of the fastener adhesive tape due to friction with the fastener insertion hole Moves upward between the layers, deforms and follows the shape of the insertion hole, fills the gap between the insertion holes, and functions as a waterproof layer, so that it is not necessary to separately perform a waterproofing process such as a caulking process. Therefore, the working efficiency is greatly improved.
Moreover, since the wound body of the adhesive tape is rich in deformation followability as described above, sufficient waterproof performance can be obtained even if the fixture is fixed in a slightly inclined state. Furthermore, since the wound body is hidden under the head of the fixture, the appearance is excellent.

  In addition, since the waterproof fixture of the present invention uses a wound body of the adhesive tape as a waterproof layer, sufficient waterproofness can be obtained by appropriately adjusting the wound condition of the adhesive tape according to the size of the fixture insertion hole. Can be secured.

  By providing a packing between the head and the wound body, double waterproofing is achieved between the wound body and the packing, and a further excellent waterproof performance can be obtained.

  Further, by suspending the waterproof rim around the head, the waterproof rim prevents intrusion of rainwater, so that more reliable waterproof performance can be obtained.

  In addition, by making the shape of the adhesive tape into a constant width part and a tapered part with a reduced width toward the head, the wound body obtained by winding around the shaft part is a bulging part at the center part This bulged portion is rich in deformation following ability and easily fills the gap of the fixture insertion hole, so that it is easy to exhibit waterproof performance.

  In addition, the adhesive tape is composed of a flexible base layer having deformation followability and an adhesive layer having a high-temperature adhesive force, so that airtightness is easily developed and good even when exposed to high temperatures outdoors. Waterproofness can be maintained.

  As the above-mentioned adhesive tape, a base layer made of flat yarn cloth laminated with polyethylene and an adhesive layer made of an acrylic adhesive are preferable.

The present invention has a head on one end of the shaft portion, the fastener having an insertion portion at the other end, the shaft portion of the vicinity of the head, is inserted an adhesive tape to Ri insertion hole greens and wrapped , characterized by comprising a wrapped body Ru fills a gap between the insertion hole deformed following to the shaft portion along the shape of the insertion hole by adhesive tape is telescoping.

In the present invention, the fixture has a head portion at one end of the shaft portion and an insertion portion at the other end, and examples thereof include a nail, a screw, and a screw. Of course, those in which a male screw is engraved in the vicinity of the insertion portion and / or in the vicinity of the head, and those in which the vicinity of the insertion portion is enlarged in diameter are included.
The shape of the head is not particularly limited, and examples thereof include a flat plate-like shape and a dish-like shape having a tapered shape with a diameter decreasing toward the axis.
The size of the fixture is not particularly limited. For example, the nail has a length of about 65 to 125 mm, the shaft has a diameter of about 3.0 to 3.5 mm, the head has a diameter of about 9 to 10 mm, and the screw has a length of about Generally, the diameter is 65 to 125 mm, the shaft has a diameter of about 3.0 to 4.0 mm, the screw diameter is about 4.0 to 5.0 mm, and the head has a diameter of about 10 to 12 mm.
The material of the fixture is preferably made of stainless steel such as SUSXM7 or SUS305. Further, the color of the fixture is preferable because bronze is not conspicuous, it matches the colors of the roof tiles, and the packing (generally black).

  In addition, when the fixture is fixed by hanging a waterproof rim around the head, the waterproof rim first prevents rainwater from entering, and the rainwater that cannot be prevented from entering by the waterproof rim is wound on the adhesive tape. Since the two-stage waterproofing function that the kimono prevents is provided, the waterproofness is further ensured. The waterproof edge extends obliquely downward or downward around the head.

  The adhesive tape used in the present invention is an adhesive or pressure-sensitive adhesive tape in which an adhesive layer or a pressure-sensitive adhesive layer is provided on a substrate layer such as cloth, paper, or film (in the present invention, both are referred to as an adhesive tape). However, it is preferable to use a flexible base material layer having deformation followability and an adhesive layer having a high-temperature adhesive force. Since the adhesive tape is flexible and has deformation followability, the wound body of the adhesive tape can follow the deformation according to the gap of the fixing tool insertion hole to airtightly fill the gap, and has high temperature adhesive force. Thus, waterproofness can be maintained over a long period of time even when a roofing material or exterior material exposed to high temperatures is fixed.

  Examples of such an adhesive tape include a tape made of an acrylic adhesive pressure-sensitive adhesive on a base material layer from a flat yarn cloth laminated with polyethylene.

The adhesive tape cannot be generally defined by the size of the fixture, such as the length and thickness, but generally it is preferably about 30 to 200 mm in length, 5 to 20 mm in width, and about 0.01 to 0.5 mm in thickness. Outside these ranges, winding around the shaft portion tends to be difficult.
The shape of the adhesive tape is as follows: (a) a ribbon having a constant width, (b) a taper having a reduced width from one side in the length direction toward the other, and (c) a length. Both ends in the direction are tapered toward the other end, (d) a ribbon-shaped portion with a constant width, and both tapers with both sides in the length direction contracted toward the end (C) and (d) are preferable, and (d) is particularly preferable. That is, in the case of (c) and (d), the wound body formed by winding around the shaft portion has a tall shape in which the central portion is bulged, and this bulged portion of the tall shape is the fixing tool insertion hole. Even if the gap is large or small, it can be applied, and it can be effectively filled by the deformation follow-up property, and the desired excellent waterproof property can be exhibited.

The wound body is provided on the shaft near the head. Preferably, it is provided directly below the head, more preferably about 1 to 3 mm below the head. The wound body is obtained by winding an adhesive tape around the shaft so that the wound body is slightly larger than the fixture insertion hole. Thus, the wrapped member is wrapped by multiple layers of adhesive tape, and because it is slightly larger than the fastener insertion hole, deformed to follow along the shape of and its insertion into a fixture insertion hole, fixed It fills the gap between the tool insertion holes and exhibits waterproofness. When the wound body is provided about 1 to 3 mm below the head, the adhesive tape moves between layers in the 1 to 3 mm space between the head and the wound body, and deforms to follow the shape of the fixture insertion hole to form a gap. It is preferable because it becomes easy to fill.

In the waterproof fixture of the present invention, by providing a packing between the head and the wound body, double waterproofing of the wound body and the packing is achieved, and the waterproof performance can be further improved. Moreover, when the edge part of an adhesive tape protrudes, there exists an effect which hides this protrusion and improves the appearance.
Such packing is not particularly limited, but EPDM rubber, silicon rubber, CR rubber, natural rubber, etc. are preferable, and the size cannot be generally defined by the size of the waterproof fixture, but for example, an outer diameter of 8 to 10 mm, an inner diameter of A thickness of about 3 to 5 mm and a thickness of about 2 to 5 mm are preferable.

  The waterproof fixture of the present invention as described above is widely used for fixing objects that require waterproof properties such as roofing materials and exterior materials. The waterproof fixture is inserted into the fixture insertion hole and fixed at the same time. The adhesive tape on the kimono moves between the layers to follow the shape of the fixture insertion hole and fills the gap in the insertion hole.As a result, it exhibits excellent prevention performance and requires a waterproofing process such as a coking process. Therefore, workability is greatly improved. When the packing is interposed, double waterproofing of the wound body and the packing is performed, and further excellent waterproof performance is obtained.
