Preferably, described light gauge cold-formed steel shape is by cold rolling shaping, compression molding or bending forming.
In above-mentioned either a program preferably, this cold bent thin-walled steel roof comprise that many roof trusses wind up, many roof truss lower edges, many perpendicular supports and many diagonal braces.
In above-mentioned either a program preferably, also comprise OSB plate, it is arranged on moistureproof breathing between paper and cold bent thin-walled steel roof.
In above-mentioned either a program preferably, also comprise warming plate, it is arranged between OSB plate and cold bent thin-walled steel roof, and this warming plate adopts polystyrene board, polyvinyl chloride panel or hard polyurethane board.
The beneficial effects of the utility model:
1. roof layouts of the present utility model is tight, and utilizes moistureproof breathing paper effectively to prevent the Seepage of rainwater, and water resistance is good, and good permeability is anticorrosion, moistureproof;
2. roof of the present utility model adopts cold bent thin-walled steel roof, improves the bearing capacity of roof panel;
3. roof of the present utility model ensure that the heat insulation effect of building, and simple installation is quick, effectively cost-saving;
4. the utility model adopts light gauge cold-formed steel shape, and from heavy and light, saving steel and structural safety are reliable, and anti-seismic performance is good.
Brief Description Of Drawings
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the utility model will become apparent.
Fig. 1-3 is respectively the structural representation of 1-3 embodiment of the present utility model;
Fig. 4 is the structural representation of cold bent thin-walled steel roof of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1
Light gauge cold-formed steel shape roof, this light gauge cold-formed steel shape roof is domatic roof, comprise roof tile 1, moistureproof breathing paper 2, cold bent thin-walled steel roof 3 and glass fibre cotton 4 from top to bottom successively, this cold bent thin-walled steel roof 3 is triangular beam form, the component form of light gauge cold-formed steel shape is U-shaped or C shape, adopt Q235 steel or Q345 steel, thickness is 1-2mm; The bottom of this cold bent thin-walled steel roof 3 is equipped with layer of glass cotton 4, and thickness is 5-10cm; Moistureproof paper 2 of breathing is laid on this cold bent thin-walled steel roof 3, it is equipped with roof tile 1; This protection against the tide is breathed paper 2 and is comprised waterproof main stor(e)y, and described waterproof main stor(e)y is provided with hole, is provided with topping, is provided with modified asphalt layer below above described waterproof main stor(e)y.
Described light gauge cold-formed steel shape is by cold rolling shaping, compression molding or bending forming.This cold bent thin-walled steel roof 3 comprises that many roof trusses wind up, many roof truss lower edges, many perpendicular supports and many diagonal braces.
Embodiment 2
Light gauge cold-formed steel shape roof, except having the structure identical with embodiment 1, also comprises OSB plate 5, and it is arranged on moistureproof breathing between paper 2 and cold bent thin-walled steel roof 3.
Embodiment 3
