Description
Technical field
The invention belongs to the roofworks field, be specifically related to a kind of single ply waterproofing prepared roofing and job practices thereof.
Background technology
The roof is that going along with sb. to guard him of covering effect and load-carrying members play in the house the superiors, and one of its topmost function is " rain of becalming ".Roofing is different according to drainage grade, can be divided into flat roof deck and pitched roof.The gradient of general flat roof deck is below 10%, and the most frequently used gradient is 2 ~ 3%, and the gradient of pitched roof is then more than 10%.China's building adopts pitched roof traditionally, and two-sided slope is arranged, slope, four sides etc.This roof pitch is bigger, and is capable of expansion and contraction, and draining is rapid, waterproof effect is also relatively good.Since the sixties,, generally changed the steel concrete flat roof deck into, adopt prefabricated circular hole roof panel and cast-in-situ steel reinforced concrete roof panel etc. more for alleviating the roofing deadweight, reduce construction costs, improving prefabricated roof assembling degree.The flat roof deck cost is lower, easy construction, simple structure, and simple appearance is applicable to the architectural plane of different shape and size, and current this type roofing is used the most extensive.
The typical construction level of existing roofing comprises following several sections: A. structure basic unit: be mostly roof panel on prefabricated circular hole slab or the cast in place reinforced bar coagulation, few part is the steel plate layer; B. at a distance from the vapour layer:, be mostly one deck adhesive bitument primer or one deck malthoid for preventing that moisture from getting into insulation layer and being provided with; C. insulation layer: two kinds of cast-in-place and prefabricated assemblings are arranged, and heat insulating material commonly used has cement perlite, piece, polystyrol plastic foam plate etc. on cinder, the aerating coagulation; D. waterproofing course: flexible waterproof layer such as can be coiled material, film also can be that pea gravel concreten adds the rigid waterproof layer that flexible filleting is formed.
Along with the development of China's Building technology in recent years, large span, light-duty and highrise building is increasing makes the distortion of roof structure bigger variation occur; And the parking lot, the appearance of roofings such as sports ground, garden makes the roofing function increase greatly again; But since the eighties; The building leakage problem becomes in China's engineering construction very distinct issues, in order to solve the roof waterproof problem, in construction, constantly increases the roof structure level; The effect that the buildings and resources that expends also often obtains is not clearly, does not meet the requirement of national building energy conservation.
Summary of the invention
