Lap joint structure and process of polymer self-adhesive film waterproof coiled material and asphalt waterproof coiled material

Abstract

The invention discloses a lap joint structure and process 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 lap joint structure and process for the polymer self-adhesive film waterproof coiled material and the asphalt waterproof coiled material involve a wall body, a polymer waterproofcoiled material body, an asphalt waterproof coiled material body and a lap joint coiled material; the polymer waterproof coiled material body and the asphalt waterproof coiled material body are flatlylaid on the wall body; the lap joint coiled material is welded to the edge of the polymer waterproof coiled material body and the edge of the asphalt waterproof coiled material body; and a temporaryfixing mechanism and a welding pressing mechanism which correspond to the polymer waterproof coiled material body and the asphalt waterproof coiled material body are arranged on the wall body. According to the lap joint structure and process of the polymer self-adhesive film waterproof coiled material and the asphalt waterproof coiled material, the attaching performance between the lap joint coiled material and the polymer waterproof coiled material body and between the lap joint coiled material and the asphalt waterproof coiled material body is guaranteed, so that the welding effect is good,the lap joint sealing performance is guaranteed, and the waterproof performance is improved.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled materials, in particular to the overlapping structure and technology of polymer self-adhesive film waterproof coiled materials and asphalt waterproof coiled materials. 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 and technology to solve the above problems
