Lap structure of polymer self-adhesive membrane waterproofing membrane and bitumen waterproofing membrane

Abstract

The invention discloses a lap joint structure of a polymer self-adhesive film waterproof coiled material and an asphalt waterproof coiled material, and relates to the field of waterproof coiled materials. The overlapping structure of the polymer self-adhesive film waterproofing membrane and the asphalt waterproofing membrane includes a wall main body, a polymer waterproofing membrane main body, an asphalt waterproofing membrane main body and an overlapping membrane, a polymer waterproofing membrane main body and asphalt The main body of the waterproof membrane is laid flat on the main body of the wall, and the overlapping membranes are respectively welded to the edges of the main body of the polymer waterproof membrane and the main body of the asphalt waterproof membrane. A temporary fixing mechanism and a welding pressing mechanism corresponding to the main body of the waterproof membrane. The overlapping structure of the polymer self-adhesive film waterproofing membrane and the asphalt waterproofing membrane ensures the adhesion between the overlapping membrane, the column of the polymer waterproofing membrane and the main body of the asphalt waterproofing membrane, making the welding effect good, Guarantee the tightness of lap joints and improve waterproof performance.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled materials, in particular to an overlapping structure of a polymer self-adhesive film waterproof coiled material and an asphalt waterproof coiled material. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no leakage connection with the building, which is the first barrier for the waterproofing of the whole project and plays a vital role in the whole project. The waterproof membrane requires good water resistance, stability to temperature changes, certain Mechanical strength, elongation and fracture resistance, as well as certain flexibility and aging resistance.

AI Technical Summary

Problems solved by technology

[0003] When laying waterproof membranes, it may be necessary to use two different waterproof membranes for laying due to the constraints of the on-site use environment. Therefore, corresponding lap joints need to be carried out at their interfaces. The existing lap joints The method is generally unilateral welding. This welding method often has a poor lap joint effect, so there may be corresponding damage and loopholes in the later stage, which makes the waterproof effect not good, and there is no corresponding effect when lap joints are performed. It is difficult to ensure the stability of the welding, which is also the main reason for the problems in the lap joint process. In view of the shortcomings of the existing technology, we design the lap joint structure of the polymer self-adhesive film waterproof membrane and the asphalt waterproof membrane , to solve the above problem
