着または溶着により接着させている。FIG. 2 is a cross-sectional view of a conventional waterproof sheet joining portion, wherein 1 and 2 are waterproof sheets, 3 is a roofing material, 4 is an adhesive for overlapping portions, and 5 is an adhesive for a construction surface. That is, in the conventional method, the waterproof sheet 1 and the waterproof sheet 2, which are partially wrapped, are adhered to each other by bonding or welding the waterproof sheets 1 and 2 as shown in FIG.
【０００４】[0004]
【発明が解決しようとする課題】このように、従来の防
水シートの接合では、（１）接着させるラップ代が多く
必要であり、しかも、ラップ部から水が侵入しやすい。As described above, in the conventional joining of waterproof sheets, (1) a large amount of lap is required for adhesion, and moreover, water easily enters from the lap portion.
【０００５】（２）防水シートの伸縮により剥がれやす

上側防水シートの端面部にシール材およびラップ内に未
加硫ゴム材などが必要である。(2) The waterproof sheet is easily peeled off due to expansion and contraction, and if it starts peeling off, the progress is fast, and (3)
A sealant is required on the end face of the upper waterproof sheet and an unvulcanized rubber material is required in the wrap.
【０００６】などの問題点があった。There are problems such as the above.
【０００７】本発明の目的は、防水シートのラップ接合
部の防水機能を高めることができる防水シート接続部を
提供することにある。It is an object of the present invention to provide a waterproof sheet connecting portion which can enhance the waterproof function of the lap joint portion of the waterproof sheet.

端縁部に沿って切り込みを入れて二重シートにし、接合
すべき防水シートの端縁部を前記二重シートの間に挿入
して溶着してなることを特徴とする。In order to achieve the above object, the waterproof sheet of the present invention is a waterproof sheet to be joined by cutting the edge portion of the waterproof sheet along the edge portion into a double sheet. The sheet is characterized in that an edge portion of the sheet is inserted between the double sheets and welded.

る。In the waterproof sheet connecting portion of the present invention, the edge of the waterproof sheet is cut along the edge to form a double sheet, and the edge of the waterproof sheet to be joined is placed between the double sheets. Since it is inserted and welded, water resistance is reduced, water intrusion is delayed, and peeling due to expansion and contraction of the waterproof sheet is reduced.

い。FIG. 1 is a sectional view of an embodiment of the waterproof sheet joining portion of the present invention. In FIG. 1, 6 is a double sheet. At the time of joining the waterproof sheets 1 and 2 at the time of constructing the waterproof sheet locally, one edge of each of the plurality of waterproof sheets is cut along the edge to form a double sheet 6 and joined. The other edges of the waterproof sheets 1 and 2 to be inserted are respectively inserted between the double sheets 6. The three layers are joined together by adhesion or welding. It should be noted that a double sheet attached to both edge portions and a waterproof sheet having no double sheet at all may be combined and bonded or required.
【００１２】[0012]
【発明の効果】本発明によれば、 （１）接着面積が広くなり、防水が少なくなる。EFFECTS OF THE INVENTION According to the present invention, (1) the adhesion area is increased and the waterproofness is reduced.
【００１３】（２）ラップ代を小さくすることができ、
水の侵入が遅くなる。(2) The lap cost can be reduced,
Water ingress is slowed.
【００１４】（３）防水シートの伸縮による剥がれが少
