Description
Technical Field
The utility model relates to a building structure technical field, concretely relates to in an antiseep roofing suitable for severe cold area.
Background
In the severe cold areas in northwest, because the influence of extreme weather such as strong sunshine, big day's difference in temperature, sand blown by wind are big, when carrying out the construction of a series of industrial factory buildings, traditional factory building roofing structure is because of receiving extreme weather to disturb, very easily takes place the fracture after one or two years and causes the roofing seepage problem, causes long-term puzzlement for the later stage use and the maintenance of factory building roofing, has influenced the normal use of factory building, has reduced the in-service use efficiency of factory building.
The original structure of the workshop roof of the region comprises a purlin-free light roof trapezoidal steel roof frame, a steel skeleton light roof panel, a flexible waterproof material (generally 3+3 hot-melt polyester tire SBS modified asphalt waterproof coiled material) and hydrophobic expansion mortar. After the factory building roof constructed by the method is influenced by extremely severe weather conditions, the outermost protective layer cracks after one or two years, the waterproof layer is directly exposed and can be quickly hardened and cracked, and finally, the roof leaks. Meanwhile, a heat-insulating layer is not separately arranged, so that a cold bridge phenomenon is easily caused.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides an antiseep roofing suitable for severe cold area can waterproof heat preservation, prevents the roofing fracture seepage.
The utility model adopts the following technical scheme:
an antiseep roofing suitable for severe cold district, the roofing is multilayer structure, includes: the purlin-free light roof trapezoidal steel roof truss comprises a steel framework light roof panel, a waterproof coating layer, a polyurethane foaming layer and an upright overlock aluminum-magnesium-manganese plate;
the purlin-free light roof trapezoidal steel roof truss is a roof bottom supporting structure, the steel skeleton light roof panel is fixedly arranged on the upper surface of the purlin-free light roof trapezoidal steel roof truss, and a waterproof coating layer is arranged on the surface of the steel skeleton light roof panel; a polyurethane foaming layer is arranged on the surface of the waterproof coating layer; the vertical serging aluminum-magnesium-manganese plate is arranged on the surface of the polyurethane foaming layer and is fixedly connected with the steel skeleton light roof panel through a support; and a fluorocarbon layer is arranged on the surface of the vertical serging aluminum-magnesium-manganese plate.
Furthermore, the support is an aluminum alloy support and is fixedly connected to the steel skeleton light roof panel frame at equal intervals through bolts.
Furthermore, the purlin-free light roof trapezoidal steel roof truss is made of Q235-B-level killed steel or boiling steel.
Furthermore, the waterproof coating layer is made of Tuoling spray quick-setting rubber asphalt waterproof coating.
Has the advantages that:
1. the polyurethane foaming layer is added, and the heat preservation and the water prevention are integrated, so that the water prevention and the heat preservation are integrated, the cracking of different materials is prevented, and the problems that the original heat preservation arrangement is not enough and a cold bridge is easy to occur are solved; moreover, the waterproof coating layer and the polyurethane foaming layer are arranged to form a multi-layer waterproof layer, so that an active effect on leakage prevention is achieved; secondly, the roofing outer layer is the vertical serging aluminium magnesium manganese board, the application of ripple aluminium magnesium manganese board, it is low to make the structure load, utilize the ripple structure can guide rainwater emission fast simultaneously, can also form the air bed in the nature between externally and the roofing waterproof insulation layer (polyurethane foaming layer), prevent to expose outdoors directly, effectively reduced the big direct influence to the waterproof layer of the day difference in temperature, the problem of severe cold extreme weather area roofing heat preservation and waterproof material receives various abominable climates to influence has been solved, the easy fracture, the problem of seepage, to and practical strong operability, reduce later stage maintenance and capital construction technique and improve the input of manpower and material resources, effectively practice thrift the overlapping investment, will promote the fail safe nature of severe cold area industry factory building vigorously.
2. The utility model discloses a scribble smart spraying rapid hardening rubber asphalt waterproof coating, this coating collect waterproof, prevention of seepage, anticorrosive, protect in an organic whole, have high ductility, impact resistance, corrosion-resistant, ageing-resistant characteristics, insensitive to ambient temperature, humidity, water resistance is excellent.
