The invention discloses a lap joint structure of a polyethylene polypropylene waterproof membrane and an SBS modified asphalt membrane and a construction method. A lap joint layer is arranged between the polyethylene polypropylene waterproof membrane on the upper layer and the SBS modified asphalt waterproof membrane on the bottom layer. The lap joint layer comprises a double-faced butyl adhesive tape layer and a polyethylene polypropylene connecting layer from bottom to top. The polyethylene polypropylene connecting layer is the polyethylene polypropylene waterproof membrane of which non-woven fabric on one face is torn off to form an adhesion face, the adhesion face adheres to the double-faced butyl adhesive tape layer, and the double-faced butyl adhesive tape layer adheres to the SBS modified asphalt waterproof membrane. The lap joint layer adheres to the polyethylene polypropylene waterproof membrane through cement adhesives. A lap joint gap between the polyethylene polypropylene waterproof membrane and the SBS modified asphalt waterproof membrane is sealed through sealing butyl tape. The two waterproof membranes are the same in the number of layers, the polyethylene polypropylene waterproof membrane and the SBS modified asphalt waterproof membrane are in corresponding lap joint layer by layer, and then staggered lap joint belts are formed. The lap joint structure is simple, convenient to operate in the construction process, low in cost, good in lap joint quality, high in integrity and good in waterproof effect.
Description
technical field [0001] The invention relates to the technical field of waterproof layer construction, in particular to an overlapping structure and construction method of a polyethylene polypropylene fiber waterproof membrane and an SBS modified asphalt membrane suitable for the construction of a flexible waterproof layer on a basement or roof. Background technique [0002] In the construction of building waterproof layers, we often encounter the problem of overlapping construction of different waterproof membranes. For example, different monomers are designed by their respective construction or design units but the basement or roof is connected, or different types of waterproof membranes need to be selected for the same waterproof area. As a flexible waterproof layer, the overlapping construction technology of the same waterproof membrane in the prior art has been basically mature, but there are relatively few studies on the overlapping construction of different waterproof m...
