Description
Technical field
The present invention relates to buildings waterproof field, particularly relate to a kind of external wall waterproof structure.
Background technology
At present, the heat preserving exterior wall of building is not mostly set up waterproofing course, generally occurs the phenomenon that wall leakage, crackle, warming plate come off after use, and the use of building and outward appearance, appearance of city, resident's safety are all had a significant impact and hidden danger.Once occur these situations, maintenance cost will be very high, maintenance difficulty is also very large, and the buildings and resources of waste is countless.In recent years, part building starts progressively to set up external wall waterproof layer, and < < external wall waterproofing tecnical regulations > > also External Wall waterproofing process has made relevant regulations.But existing external wall waterproof system still exists many defects and deficiency, waterproof effect is undesirable.
Existing external wall waterproof can only be built up in waterproofing course between insulation layer and structure wall, can not be built up between insulation layer and surface layer, this will cause exterior-wall heat insulation with fixture fixedly during warming plate, self-tapping screw can destroy the globality of the waterproofing course between structure wall and surface layer, causes the hidden danger of leaking.
And traditional outer wall heat preservation system grid cloth is wherein very crisp, along with the increase of service life, can lose pliability, very crisp frangibility, the cracking of irresistible surface layer.Anticracking grout wherein, most of is used polymer glue powder modulation, and part adopts polymer emulsion, and no matter which kind of, be all to have emphasized that crack resistance ignored water proofing property.Therefore, just generally there is Seepage, and then cracking.
When anticracking grout seepage and cracking, water just enters insulation layer, thereby enter interior wall, in insulation layer, have after moisture, destruction in autumn and winter season due to freeze thawing circulation, insulation layer will come off, and the surface layer that sticks on also will together come off with insulation layer, cause exterior wall and waterproofing course to destroy, resident's personal safety is caused to serious threat.
As can be seen here, above-mentioned existing a kind of external wall waterproof structure, in structure and use, obviously still has inconvenience and defect, and is urgently further improved.How to found a kind of waterproofing course be difficult for destroyed, crack resistance good, the new external wall waterproof structure of good water-proof effect, long service life, at current industry tool, be of great significance.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of external wall waterproof structure, make its waterproofing course be difficult for destroyed, crack resistance good, good water-proof effect, long service life, can effectively avoid body of wall to come off.
For solving the problems of the technologies described above, the invention provides a kind of external wall waterproof structure, comprise polymer cement waterproof paint layer, stitch and knit mylar and waterproof anti-crack mortar layer, polymer cement waterproof paint layer is coated on insulating layer of external wall or leveling layer, described seam is knitted mylar and is sticked on polymer cement waterproof paint layer, and water-proofing anticracking mortar layer is coated in described seam and knits on mylar.
Further, the thickness sum that described polymer cement waterproof paint layer and seam are knitted mylar is 0.8-1.3mm.
The thickness sum that described polymer cement waterproof paint layer and seam are knitted mylar is 1.2mm.
