Waterproof structure and manufacturing method thereof

Abstract

The invention relates to a waterproof structure and a manufacturing method thereof. The waterproof structure is used for waterproofing of detail joints on roofing and comprises a waterproof coiled material layer and a waterproof coating layer which is arranged on the position of the detail joints and is overlapped and struck with the waterproof coiled material layer, wherein the inside of the waterproof coating layer can comprise a reinforcing layer made of polyester or nylon non-woven fabrics or textile fabrics; and the material of the waterproof coating layer is exposed polyurea waterproof paint or modified waterproof paint thereof, exposed polyurethane waterproof paint or modified waterproof paint thereof, exposed polymethyl methacrylate waterproof paint or modified waterproof paint thereof or exposed polystyrene-ethylene-butadiene-styrene or modified waterproof paint thereof. Because the waterproof coating layer of the waterproof structure has large bonding force, strong capability to resist stretching and high elasticity, when the detail joints on the roofing are deformed because of gusty condition or other reasons, the waterproof coating layer is not destroyed and still has excellent waterproof effect.

Description

technical field [0001] The invention relates to a waterproof structure in the field of construction, in particular to a waterproof structure using exposed elastic waterproof coatings and waterproof rolls or sheets for roof detail nodes and a manufacturing method thereof. Background technique [0002] see figure 1 Shown is the schematic diagram of existing roof waterproof structure. In the existing roof waterproof structure, it mainly adopts waterproof coiled material (or waterproof sheet) 13 to be laid on the roof plane 11, and when encountering the vertical wall 12, it passes through the waterproof coiled material 14 pasted on the vertical wall. The joints are overlapped, and waterproof sealing is carried out at the overlapping joints to achieve the purpose of roof waterproofing. But in the existing roof waterproof structure, for the waterproof membrane layer, whether it is hot construction, cold construction, self-adhesive or mechanical fixation, the detail nodes are mor...

AI Technical Summary

Problems solved by technology

But in the existing roof waterproof structure, for the waterproof membrane layer, whether it is hot construction, cold construction, self-adhesive or mechanical fixation, the detail nodes are more likely to leak (such as the waterproof membrane 13 and the waterproof membrane 14) Lap joint), these detail nodes are generally roof flashing, parapet, gutter, gutter, cornice, wall pipe, water drop, roof pipe protruding, seam, external corner, internal corner and roof edge, etc. , these detail nodes are prone to water leakage because the coil or sheet is difficult to construct in these places, prone to errors or insufficient bonding at the edge of the roof

In addition, the deformation of these details is large, which is also the reason why the coil or sheet is prone to water leakage in these places.

[0003] In windy weather, the fast-flowing wind will form an upward suction force on the existing roof waterproof layer. Since the detailed nodes of the roof belong to the overlapping parts of at least two parts of the coil, the adhesive force is not enough, and it is easy to tear or deform. , forming gaps causing water leakage

Or, under natural conditions such as minor earthquakes, strong winds, thermal expansion and contraction, etc., the walls and roof of the building will be slightly deformed. At this time, the waterproof structure of the existing roof detail nodes will be damaged, resulting in water leakage or Leakage, for the coiled material at the edge of the roof due to strong winds, it is easy to uncover, resulting in leakage

[0004] The technical problem to be solved in the present invention is to provide a waterproof method for roof detail nodes, which overcomes the defects of the prior art such as difficult construction, insufficient adhesion, insufficient flexibility, and poor waterproof effect
