れ、防水性が損われるという問題があつた。Conventional technology Conventionally, a waterproof sheet made of a synthetic resin sheet such as soft polyvinyl chloride or a rubber sheet has been used to waterproof a flat roof. The connection side edges of mutually adjacent waterproof sheets are overlapped, and the lower side edge of these side edges is fixed to the wall via a joint piece and a fixture,
The upper side edge was joined to the lower fixed side edge with an adhesive. However, such waterproof sheets made of synthetic resin sheets or rubber sheets are soft and have low strength, and therefore people cannot walk on them. Therefore, instead of such waterproof sheets made of synthetic resin sheets or rubber sheets, strong waterproof resin-coated metal plates (waterproof sheets) made of polyvinyl chloride resin-coated steel plates (hereinafter referred to as PVC steel plates) are used to waterproof flat roofs. It was considered to be installed on the wall, but
Because PVC steel sheets have a metal steel plate as their core material, they expand and contract very significantly due to temperature differences between day and night or due to seasonal changes. As in the case of sheets, among the mutually overlapping connection side edges of adjacent PVC steel plates, the lower side edge is fixed to the wall, and the upper side edge is fixed to the lower fixed side edge. If they were to be joined via a connecting agent, there was a problem that the joint would be broken due to the expansion and contraction of the PVC steel plate due to the temperature difference, and the waterproof property would be impaired.

等における防水装置を要旨としている。Means for Solving the Problems In order to achieve the above object, this invention uses a large number of waterproof rectangular synthetic resin-coated metal plates that are laid out on the surface of a wall to be waterproofed, such as a flat roof, and adjacent waterproof resin-coated metal plates. Equipped with an elastic belt-like connecting sheet made of synthetic resin or rubber that connects the connection side edges of the coated metal plates, and a fixture that fixes the required side edges of each waterproof resin coated metal plate to the wall. In waterproofing devices for flat roofs, etc., the connection side ends of mutually adjacent waterproofing resin-coated metal plates are joined to each other with one side edge facing up and the other side edge facing down. The side edges of the lower waterproof resin-coated metal plate are fixed to the wall with the fixing device, and the side edges of the upper waterproof resin-coated metal plate are free. As a whole, two mutually perpendicular side edges of each waterproof resin-coated metal plate are fixed by a fixture, and the remaining two mutually perpendicular side edges are free, and the upper side of the overlapping state A band-shaped connecting sheet is passed between the free side edge of the waterproof resin-coated metal plate and the part near the fixed side edge of the lower waterproof resin-coated metal plate,
Both side edges of the connecting sheet are joined to the upper free side edge and the lower fixed side edge portion via an adhesive layer, and are not joined to the center part of the elastic band-like connecting sheet. The main focus is on waterproofing devices for flat roofs, etc., for which some parts remain.

When both the joint surfaces are made of vinyl chloride resin, vinyl chloride resin or a copolymer of vinyl chloride and vinyl acetate, ethylene or propylene is used in a solvent such as tetrahydrofuran, methyl isobutyl ketone, toluene and cyclohexanone alone or in combination. It is desirable to use a solution-based adhesive that dissolves in the adhesive and has a viscosity of 2000 to 5000 cps, preferably 3000 to 4000 cps. The amount of this adhesive applied is 100
-600g/ m2 , preferably 300-400g/ m2 .
上記塩化ビニル樹脂またはその共重合物を含む
溶液型接着剤の粘度が2000cps未満であれば、隙
間充填性が悪く、接着後に充分な水密性が得られ
ない。また5000cpsを越えると、粘性が高すぎて、
塗布作業性が悪くなるので好ましくない。 If the viscosity of the solution-type adhesive containing the vinyl chloride resin or its copolymer is less than 2000 cps, the gap filling property will be poor and sufficient watertightness will not be obtained after bonding. Also, if it exceeds 5000cps, the viscosity is too high,
This is not preferable because it impairs coating workability.
また同接着剤の塗布量が100ｇ／m2未満であれ

性が充分でなく、漏水のおそれがある。また600
ｇ／m2を越えると接着剤中の溶剤により塩ビ鋼板

い。 Furthermore, if the amount of the adhesive applied is less than 100 g/m 2 , not only will sufficient adhesive strength not be obtained, but watertightness will not be sufficient and there is a risk of water leakage. 600 again
If it exceeds g/m 2 , the vinyl chloride waterproofing resin coating layer on the surface of the vinyl chloride steel plate will swell and roll up due to the solvent in the adhesive, and this will peel off, which is not preferable.

膨脹収縮に追従し易いという利点がある。 Note that the band-shaped connecting sheet 9 is passed over and joined to the adjacent waterproof resin-coated metal plates 2, but this is only necessary when almost the entire lower surface of the connecting sheet 9 is joined to the waterproof resin-coated metal plate 2. For example, a non-bonding sheet (not shown) of a required width made of kraft paper or the like coated with an adhesive on one side is pasted in advance at a predetermined location on the waterproof resin-coated metal plate 2.
In some cases, only the side edges of the connecting sheet 9 are joined to the waterproof resin-coated metal plate 2 via the adhesive layer 10 without joining the width center portion of the band-like connecting sheet 9 corresponding to this joining sheet. According to the latter, the elongation of the connecting sheet 9 becomes very large due to the presence of the non-joined portion, and there is an advantage that it easily follows the expansion and contraction of the waterproof resin-coated metal plate 2.

It is desirable to fill the sealing material 12. Such a sealing material 12 may be made of the same material as the above-mentioned solution type adhesive containing a vinyl chloride resin and a solvent, and having a higher viscosity.

ることができるという効果を奏する。Effects of the invention As mentioned above, this invention has a large number of waterproof rectangular synthetic resin-coated metal plates arranged on the surface of a wall to be waterproofed, such as a flat roof, and the connecting end of the adjacent waterproof resin-coated metal plates. In a waterproofing device for a flat roof, etc., which is equipped with a stretchable belt-like connecting sheet made of synthetic resin or rubber that connects the two pieces, and a fixture that fixes the required side edge of each waterproofing resin-coated metal plate to the wall, The connection side ends of mutually adjacent waterproof resin-coated metal plates are overlapped with one side edge on top and the other side edge on the bottom without being joined to each other, and the bottom side The side edges of the upper waterproof resin-coated metal plate are fixed to the wall with the fixing device, and the side edges of the upper waterproof resin-coated metal plate are free, and each waterproof resin-coated metal plate is fixed as a whole to the wall. Two mutually perpendicular side edges of the plate are fixed by a fixture, and the remaining two mutually perpendicular side edges are free, and the upper waterproof resin-coated metal plate in the overlapping state is A band-shaped connecting sheet is passed between the free side edge and the portion near the fixed side edge of the lower waterproof resin-coated metal plate, and the both side edges of the connecting sheet are connected to the upper free side edge. It is bonded to the lower fixed side edge part via an adhesive layer, and a non-bonded part is left in the center of the elastic band-shaped connecting sheet, so it is made of high-strength PVC. Walls such as flat roofs can be waterproofed using waterproof resin-coated metal plates such as steel plates, making it possible for people to walk on them. Even in cases where the expansion and contraction of waterproof resin-coated metal plates such as PVC steel plates is extremely large, the expansion and contraction of each waterproof resin-coated metal plate is not inhibited.
Due to the relative expansion and contraction of the strip-like connecting sheet as the waterproofing resin-coated metal plate expands and contracts, this can be sufficiently absorbed. It has the effect of being able to maintain excellent waterproof properties for a long period of time without being broken.
