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
The present invention relates to a kind of waterproof construction of building field, particularly relate to a kind of waterproof construction and manufacture method thereof that is used for the thin portion of roofing node with exposed type elastic water proofing paint cooperation waterproof roll or sheet material.
Background technology
Seeing also shown in Figure 1ly, is the schematic diagram of existing roof covering water-proof structure.In existing roof covering water-proof structure, it mainly is to adopt waterproof roll (perhaps waterproof sheet) 13 to be laid on the roof plan 11, when running into straight wall 12, by with stick on straight wall on waterproof roll 14 overlap mutually, and carry out waterproof sealing in lap-joint, realize the purpose of roof waterproof.But in existing roof covering water-proof structure, for the waterproof roll layer, no matter be heat construction, cold construction, self-adhesion or mechanical fixation, thin portion node is all than being easier to take place seepage (for example clinch of waterproof roll 13 and waterproof roll 14), these thin portion nodes are generally the roofing flashing, parapet, gutter, eaves gutter, cornice, pipeline through walls, the water mouth that falls, stretch out the roofing pipeline, seam, external corner, inner corner trim and roofing edge etc., it is because coiled material or sheet material are comparatively difficult when these local constructions that these thin portion nodes easily leak, be easy to make mistakes or not enough in roofing edge adhesion.In addition, these thin portion deformation variablees are big, also are to cause coiled material or sheet material in these local reasons of easily leaking.
Running into strong wind weather, the strong wind that flows can form suction upwards to existing roof waterproof layer fast, because the thin portion node of roofing belongs to the overlapping part of two parts coiled material at least, cement strength is not enough, tear easily or be out of shape, the formation slit is caused and is leaked.Perhaps, building are under external force such as slight earthquake, strong wind, natural conditions such as expand with heat and contract with cold, slight deformation can take place in body of wall and roofing, can damage this moment to the waterproof construction of the thin portion node of existing roofing, and then cause and leak or seepage,, be easy to open because of wind effect for roofing edge coiled material, cause seepage.
The technical issues that need to address of the present invention are to provide the waterproof method of the thin portion of a kind of roofing node, and it is big to overcome the prior art difficulty of construction, and bonding force is not enough, and are flexible not enough, defectives such as waterproof effect difference.
