納まりではなかった。Conventionally, as shown in FIG. 4, a waterproof sheet laid on a flat roof has a structure in which the peripheral portion of the waterproof sheet 1 is directly bonded and joined to a fixing strip steel plate 3 attached to a tip end of an eaves fitting 2. For this reason, when the joint portion 4 where the steel plates abut each other moves minutely under the influence of an external force, or expands and contracts due to a temperature change, the waterproof sheet in this portion is always under an external force, and It was not a safe fit for the durability of the seat.

防水シートの接合構造を提案するにある。The present invention has been made in view of the above circumstances. The purpose of the waterproof sheet is to improve the durability of the joint at the tip of the eaves of the waterproof sheet without the fluctuation of the joint part where the fixing strips abut but directly affect the waterproof sheet laid thereon. The idea is to propose a joint structure.

固着することなく添付けてあることを特徴とする。This joint structure of a waterproof sheet is a sheet waterproof joint structure in which an edge of a waterproof sheet laid on a flat roof is fixed on a fixing strip attached to a tip of a portion to which the waterproof sheet is attached. The joints where the fixing strips abut against each other close the joints by applying an insulating tape, and folded protective tapes are attached to the upper and lower surfaces of the joints without being fixed to the insulating tape. It is characterized by the following.

鋼板３′を用いてある。Hereinafter, description will be made with reference to the illustrated embodiment. In FIGS. 1, 2, and 3, a strip steel plate 3 for fixing is fixed to the top surface of the tip portion of the eaves metal fitting 2 of the flat roof with a screw 5, and a butyl rubber tape 6 having double-sided adhesion is interposed therebetween to adhere to the watertight. The property is given. The joint 4 where the ends of the strip steel plates 3 and 3 are butted together is covered with an insulating tape to close the joint 4.
A protective tape 8 is formed on the upper surface of the insulating tape 7 and the lower surface of the strip steel plate 3 by folding the protection tape 8 at the tip of the eave, and is attached without being fixed to the insulating tape nor to the lower surface of the strip steel plate 3. is there. The edge of the waterproof sheet 1 laid on the flat roof is adhesively fixed to the upper surface of the fixing strip steel plate 3 attached to the tip of the attached portion of the waterproof sheet 1 and the upper surface of the protective tape 8 attached to the joint. . Note that an L-shaped strip steel plate 3 'as a corner accessory is used in the corner of the eaves of the flat roof.

折り返り端を重ね合せ、環状となし添付けてもよい。As the insulating tape used in this bonding structure, a synthetic resin film having relatively flexibility is used. It is preferable that the protective tape has a width equal to or wider than the joint tape, has the same or higher elasticity as the waterproof sheet, and has good adhesion to the waterproof sheet. For example, when the waterproof sheet is made of a vinyl chloride resin as a base material, a resin sheet of the same kind is preferable. Usually, the protection tape is folded in a U-shape and attached to the joint, but is not limited to the U-shape.
The folded ends may be overlapped and attached without a ring.

ができる。The joint structure of the waterproof sheet is constituted as described above. As shown in FIG. 3, the joint portion where the ends of the fixing strip steel plates 3 and 3 are joined is closed by attaching an insulating tape 7 thereon. A folded back protective tape 8 is attached to the lower surface without being fixed to the insulating tape 7. Since the waterproof sheet has a structure that is fixed on it, it is insulated from the joint between the strip steel plates 3, 3, and the joint changes do not act directly on the waterproof sheet, but use a protective tape wider than the joint width. It is transmitted in a relaxed manner. Therefore, it is possible to prevent the waterproof sheet from being damaged due to a change in joint.
