Construction method for improving waterproof effect of coiled materials

Abstract

The invention discloses a construction method for improving the waterproof effect of coiled materials. The method comprises the following steps that a concrete base layer is cleaned; the base layer is coated and sprayed with a base layer treating agent; additional layers are pasted to internal and external corners, pipeline root portions and deformation joint positions; hot melting pasting construction is conducted on the middle of the waterproof coiled materials, and adjacent waterproof coiled materials are connected at the edge positions in a vertical overlapped mode; a preheated soldering iron enables a gentle tilt angle to be formed on the overlap connection edge of the lower-layer waterproof coiled materials at the overlap connection position through soldering in the overlap connection direction; hot melting and edge sealing are conducted on the waterproof coiled materials. According to the construction method for improving the waterproof effect of the coiled materials, during waterproof coiled material hot melting pasting construction, the preheated soldering iron enables the tilt angle to be formed on the edge of the waterproof coiled materials, no gaps exit at the overlap connection positions of the adjacent waterproof coiled materials, the integration of the waterproof coiled materials on the outer layer of the structure is ensured, the problem that water lines are formed by coiled material waterproof construction overlap connection joints is solved, the water leakage hidden danger caused by construction technological defects is eradiated, and the waterproof effect of a structural base plate is significantly improved on the premise that the cost is not increased and construction is convenient.

Description

technical field [0001] The invention belongs to the field of waterproof engineering, and in particular relates to a waterproof construction method for coiled materials. Background technique [0002] At this stage, membrane waterproofing is still the mainstream of building waterproofing, and membrane waterproofing is mostly used for waterproofing of building basements, exterior walls and roofs. Although the membrane waterproofing process is very mature, there are still hidden dangers of water leakage in traditional membrane waterproofing. After research, it is found that the hidden dangers of water leakage at the lap joints of traditional construction technology account for a large proportion, and it is difficult to detect during construction. Therefore, the further elimination of coils The hidden danger of water leakage that is difficult to detect and extremely harmful in the waterproof construction of materials is particularly important. [0003] Such as figure 1 and fi...
