Technical field
The present invention relates to waterproofing work technical field, specifically a kind of seam class water proof structure and its construction technology and application.
Background technology
In recent years, leakage ratio is very high caused by building seam class, and repairs difficult, maintenance cost height.Building
Seam class can be divided into crack, gable seam, construction joint, deformation joint (expansion joint, subsiding crack) etc. again.The gap of building, due to by
The factors such as geology is flexible, sedimentation and the variation of circumstance of temperature difference influence, and not only easy to produce deformation and variation is extremely frequent, stretch and
The deformation effect time caused by sedimentation is longer, and deformation caused by circumstance of temperature difference can then influence deformation journey with the variation of weather
Degree, the caused deformation of above-mentioned factor can make the waterproof material at gap position for a long time in the state stretched repeatedly, cause to prevent
Water material premature aging, causes leak.
The structure position waterproof that gap occurs, construction is complicated mostly, is related to that material category is various, waterproof construction difficulty is big,
In order to ensure the reliability of gap waterproof, at present stitch class waterproof construction mainly follow " rigid flexible system, multi-way prevention, composite water-proof,
The principle of encapsulation process ".
Currently, the major way of seam class waterproof is filled to gap using non-ignitable class thermal insulation material, then in seam class

Fruit cannot find specific damaged and rejected region, can not just repair, can only do waterproof again.Prevented using coiled material opposite joint class
There is also the problems such as complicated, program are various, difficulty of construction is big and manual time is of high cost of constructing when water process, and after construction
The water proof structure creep properties of formation and extensibility are very limited.
Also there is the processing squeezed into smaller gap after filler and directly use water-repellent paint brushing slit surfaces at present
Method, but filler there are adhesion strengths it is poor, elongation percentage is not high, easy to crack the problems such as, then there is tensile strength in water-repellent paint
Poor problem, such method are easy to be torn when for stitching class waterproof with the deformation waterproof coating in gap, so as to cause
Waterproof failure, thus now it is less using water-repellent paint come carry out stitch class waterproof.
Therefore, find one kind can bear major structure of construction and other building enclosures malformation, sink cracking or
During expanding with heat and contract with cold etc. to the stretching of waterproof layer, tear and shear the effects that, and with good homogeneity and energy
The organic whole that a good seal is formed with basal plane is not in that make some alterations a piece of waterproof layer structure be current to be badly in need of solution for leakage one
Certainly the problem of.
