Abstract
The invention discloses a single-layer waterproof prepared roofing and a construction method thereof. The roofing comprises a base layer, a vapor-proof layer, a heat preservation layer and a waterproof layer, wherein the base layer is a concrete roofing board or a steel plate; the vapor-proof layer, the heat preservation layer and the waterproof layer are sequentially arranged on the base layer; the vapor-proof layer is a polyethylene film layer which is laid on the base layer in a border adhibiting way; the heat preservation layer is fixed on the base layer through a fastening gasket and a fastening nail; and the waterproof layer is a single-layer thermoplastic polyolefin waterproof roll layer or a single-layer polyvinyl chloride waterproof roll layer, and is fixed on the base layer in a mechanical fixing way. The roofing is simple in structural hierarchy and high in degree of design freedom; and in addition, the single-layer operation of a wide roll is adopted, so that structural layers and operation levels are reduced, the weight is reduced, the materials are saved, and the construction cost is lowered.
Description
Technical field
The invention belongs to roofworks field, be specifically related to a kind of single ply waterproofing prepared roofing and job practices thereof.
Background technology
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 more than 10%.China's building adopts pitched roof traditionally, has two-sided slope, slope, four sides etc.This roof pitch is larger, capable of expansion and contraction, and draining is rapid, waterproof effect is also relatively good.Since the sixties, for alleviating roofing deadweight, reduce construction costs, improving prefabricated roof assembling degree, generally change reinforced concrete flat roof into, adopt prefabricated circular hole roof panel and cast-in-situ steel reinforced concrete roof panel etc. more.Flat roof deck cost is lower, easy construction, simple structure, and outward appearance is succinct, is applicable to various shapes and big or small architectural plane, and current this class roofing is most widely used.
The typical construction level of existing roofing comprises following several part: A. structure basic unit: mostly be roof panel on prefabricated circular hole slab or cast in place reinforced bar coagulation, small part is steel plate layer; B. every vapour layer: for preventing that moisture from entering insulation layer setting, mostly be one deck adhesive bitument primer or one deck malthoid; C. insulation layer: have two kinds of cast-in-place and prefabrication and assembly constructions, conventional heat insulating material has cement perlite, piece, polystyrol plastic foam plate etc. on cinder, aerating coagulation; D. waterproofing course: the flexible waterproof layer such as can be coiled material, film can be also that pea gravel concreten adds the rigid waterproof layer that flexible filleting forms.
Along with the development of China's Building technology in recent years, large span, light-duty and highrise building is increasing, make the distortion of roof structure occur larger variation, and parking lot, the appearance of the roofing such as sports ground, garden, make again roofing function greatly increase, but since the eighties, building leakage problem becomes in China's engineering construction very distinct issues, in order to solve Water-proof Measures of Roofs, in construction, constantly increase roof structure level, the buildings and resources expending yet effect many and that obtain is not clearly, does not meet the requirement of national building energy conservation.
