A kind of integral seamless light-steel roofing system
Technical field
The utility model relates to the housing roof technical field of buildings, specifically is a kind of integral seamless light-steel roofing system.
Background technology
Steel building is with plurality of advantages such as body are light, attractive in appearance, the construction period is short, span is big, be subjected to numerous owners' favor, steel building is swept across on both sides of the Changjiang River fast, but the roof waterproof system that matches seems and does not catch up with paces, the roofing seepage problem has become the common fault of steel work industry, perplex the steel work industry always, obstructing the fast development of steel work industry.Generally popular colored steel roofing, Roof Design does not have this concept of waterproof substantially, to construct lack of standardization in addition, and the result causes numerous steel-structure factory building percolating water especially severes, and the economic loss that the economic loss that infiltration directly causes and maintenance cause allows numerous owners suffer untold misery.
Aluminium sheet, copper coin roofing effect are quite a lot of, but involve great expense, and the component that match in addition and construction technology thereof do not catch up with it can't large tracts of land be promoted.Current colored steel roof waterpoof material adopts maximum still PVC waterproof rolls, and material itself is good product, but its empty shop construction also is avoiding greatly in the roof waterproof, and problem usually occurs.
The utility model content
For addressing the above problem, the utility model provides a kind of integral seamless light-steel roofing system.
The technical scheme that its technical problem that solves the utility model adopts is, this integral seamless light-steel roofing system, comprise roofing, ridge and eaves gutter, described roofing, ridge and covering one deck color steel above the eaves gutter, integral spray polyurethane foam layer above the described color steel, cover one layer of polymeric anticracking grout layer above the described polyurethane foam layer, be provided with the alkaline-resisting grid cloth of one deck cracking resistance in the middle of the described polymers anti-cracking mortar layer, the thickness of the alkaline-resisting grid cloth of described cracking resistance is 3mm-6mm; Be provided with one deck uvioresistant water-repellent paint above the described polymers anti-cracking mortar layer;
Described color steel by bolt on crossbeam; Described ridge place is provided with sealing plate.
The beneficial effect that the utility model produces is: color steel is factory process, is easy to moulding and transportation, and quick construction is convenient, and technology is ripe general at present; Polyurethane foam layer adhesion stress is extremely strong, and heat insulation property is good; Water resistance is good: because rate of closed hole is greater than more than 90%, thereby have excellent water-proof function; Integral sealing does not have the seamless bonding of cavity, and the production efficiency height is particularly useful for the insulation of large tracts of land, special-shaped object, and shaping speed is fast, the production efficiency height; Very strong taking off property of wind resistance is arranged, good flame resistance; Polymers anti-cracking mortar has that flexible height, product adhesion strength height, weatherability height, water-proofing anticracking are effective, use environmental protection, plurality of advantages such as easy to operate; The uvioresistant waterproof coating is mainly used in the protection of polyurethane; The utility model efficiently solves the insulation of steel work roofing, heat insulation, cold bridge, waterproof, the problem of a series of present existence such as indoor condensing drip, make again big roofing form an integral body by spray coating foaming, can accomplish roofing zero slit, stopped the possibility of leaking, and convenient and quick construction, controllable thickness need not be safeguarded in the use, be prolonged the roofing life-span, for the owner has saved the maintenance spending.

The specific embodiment
Below in conjunction with accompanying drawing and example, the utility model is further specified.
This integral seamless light-steel roofing system, comprise roofing, ridge and eaves gutter 9, described roofing, ridge and covering one deck color steel 1 above the eaves gutter 9, integral spray polyurethane foam layer 2 above the described color steel 1, cover one layer of polymeric anticracking grout layer 3 above the described polyurethane foam layer 2, be provided with the alkaline-resisting grid cloth 4 of one deck cracking resistance in the middle of the described polymers anti-cracking mortar layer 3, the thickness of the alkaline-resisting grid cloth 4 of described cracking resistance is 3mm-6mm; Be provided with one deck uvioresistant water-repellent paint 5 above the described polymers anti-cracking mortar layer 3; Described color steel 1 is fixed on the crossbeam 7 by bolt 6; Described ridge place is provided with sealing plate 8.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
The technology that the utility model is not described in detail, shape, structure partly are known technology.
