(2) laying overlays Macromolecular self-adhesive membrane waterproof roll, and make the described basic unit overlaying Macromolecular self-adhesive membrane waterproof roll towards concrete cushion, the self-adhesion glued membrane of coiled material and weathering layer are upwards;
(3) when adjacent overlay Macromolecular self-adhesive membrane waterproof roll overlap at long side direction time, self-adhesive tack coat and barrier film in the long edge lap region of coiled material is utilized to carry out lap side seam, concrete steps are: the barrier film under overlap edge places both tearing off, layer coiled material covered, carry out self-adhesion overlap joint, and with roller compaction coiled material lapping limit, discharge the bubble of lap-joint, tightly compactedly to cement, the long edge lap width of coiled material is not less than 75mm;
When adjacent overlay Macromolecular self-adhesive membrane waterproof roll to cut out stitching position overlap joint in the thin portion of minor face and negative and positive angle time, adopt docking adhesive tape lap side seam, concrete steps are: the self-adhesion glued membrane under removing within the scope of overlap joint on layer coiled material and weathering layer, by two-sided docking adhesive tape overlap joint bonding between coiled material lapping part, and roll with pressure roller, the upper and lower two layers of coiled materials compacting of lap-joint is cemented, and edge-jointing adhesive bandwidth is not less than 80mm;
When multilayer overlays Macromolecular self-adhesive membrane waterproof roll overlap joint generation overlapping region, within the scope of multilayer overlap, lap gap between the multilayer coiled material fluid sealant matched with coiled material basic unit is obturaged, the more described docking adhesive tape lapping construction carried out between adjacent two layers of coiled materials lap-joint or self-adhesion lapping construction.
Beneficial effect of the present invention is:
1, Macromolecular self-adhesive membrane waterproof roll quality is relatively hard, not yielding, in coiled material lapping process, within the scope of overlap joint, produce protruding because two layers of coiled materials is stacked with at seam crossing, in multilayer overlap joint process seam crossing protruding and its on cover between coiled material and be easy to occur gap, produce seam mouth, bring permeable hidden danger, cause the seepage of concrete upstream face coil waterproof layer.This Macromolecular self-adhesive membrane waterproof roll closure seam method restrained effectively the seepage gap that multilayer overlap joint process produces.
2, different according to Macromolecular self-adhesive membrane waterproof roll joint forms, as splicing overlap joint etc. is cut out in long edge lap, minor face overlap joint, thin portion, negative and positive angle, comprehensively select rationally effective joint filler, the two-sided docking adhesive tape of coiled material as supporting, fluid sealant, coiled material long overlap limit self-adhesive etc., suitable construction method is adopted to carry out lap side seam, conservative control coiled material lapping width, reaches and is completely stained with overlap joint, and final formation set of system is various, tight seam construction reliably.
