なされているが、完全な防水性を期待することは
できなかつた。 Conventionally, there has been a risk that the joint portion of a waterproof sheet cannot resist tension due to cracks in the underlying concrete or contraction of the waterproof sheet itself, and the joint portion opens and water leaks from this portion. For this reason, various studies have been carried out on countermeasures for the joint part, but it has not been possible to expect complete waterproofness.

The present invention provides a waterproof construction method using a waterproof sheet that can maintain the

うに自由に剥離しうるものである。 To explain the construction method of the present invention with reference to the accompanying drawings, FIG. 1 shows a plan view of a waterproof sheet S in which an asphalt roofing 1 and a synthetic resin film 3 are laminated, and FIG. 2 shows a sectional view thereof. This waterproof sheet S is made by pasting a synthetic resin film 3 on one side of the asphalt roofing 1 with an adhesive. 4 was formed. Then, a small unbonded portion 4' is formed on the side of the overhang where the asphalt roofing is to be joined. Reference numeral 4' in the figure indicates an unbonded portion that is not pasted with this adhesive, and this unbonded portion 4' can be freely peeled off as shown in FIG.

ものである。 In the present invention, the waterproof sheet specially processed and formed in this way is pasted onto the base concrete 2 with adhesive 6, and when installing, the surface of the asphalt roofing 1 is the bottom surface. , the synthetic resin film 3 is attached with the surface facing upward, and the joint part A is formed by overlapping the ends of the asphalt roofings 1 and 1'. At this time, as shown in FIG. 3, the unbonded part 4' of the joint part 4 at the end of the synthetic resin film 3 of the asphalt roofing 1' is folded in half and bonded to the lower surface of the asphalt roofing 1 on the overlapping side. . Code 5 in the diagram
indicates the waterproof sealing material placed on the joint.
このようにして第５図に示すように一面に貼設
することによつて陸屋根あるいはビル屋上の防水
層が完成する。 In this manner, the waterproof layer on the flat roof or the roof of the building is completed by pasting it all over the surface as shown in FIG.

なおも完全な防水性を期待できるものである。 In the present invention, by forming the joint part A in this way, even if a crack occurs in the base concrete 2 and a tensile force P is generated in the upper waterproof layer as shown by the arrow, normally The joint part A is open, but in the present invention, the synthetic resin film is also a constituent material that forms the joint part of the waterproof sheet, so the joint part is not opened and the joint part is made of synthetic resin as shown in A' in Fig. 4. The unadhered portion 4' of the folded film is pulled out and remains completely waterproof.

費用が省けるという画期的効果を奏するものであ
る。 Therefore, when using the waterproofing method of the present invention, the watertightness of the joint portion of the waterproof sheet, which has not been solved in the past, becomes complete, and the cost required for repairing water leakage can be saved, which is an epoch-making effect.
