Abstract
The invention relates to a cold-bending thin-wall steel structure polyurethane sandwich steel plate roof system. The cold-bending thin-wall steel structure polyurethane sandwich steel plate roof system comprises plasterboard and a cold-bending thin-wall steel truss, wherein the cold-bending thin-wall steel truss is erected on the plasterboard. The cold-bending thin-wall steel structure polyurethane sandwich steel plate roof system further comprises a polyurethane sandwich steel plate, and the polyurethane sandwich steel plate is fixed to the cold-bending thin-wall steel truss through screws. Compared with the prior art, the cold-bending thin-wall steel structure polyurethane sandwich steel plate roof system has the advantages of being good in waterproofness, force bearing performance and heat preserving effect, easy, convenient and fast to install and the like.
Description
Technical field
The present invention relates to a kind of building roofing system, especially relate to a kind of light gauge cold-formed steel shape structure polyurethane sandwich steel plate roofing system.
Background technology
Roofing is the most complicated, the most important containment system of building.Its importance be embodied in building roof be rain, snow, sunshine topmost acceptor, structure set is gone along with sb. to guard him, thermal insulation, waterproof and dampproof in one.The building technology of cold bending thin wall steel work, builds on basis and develops at wooden construction, become a kind of physical property excellence, space and form flexibly, be easy to build, various informative maturation construction system.
As shown in Figure 1, traditional cold bending thin wall steel house plane system is by gypsum plank 2, glass wool 4, light gauge cold-formed steel shape truss 1, OSB plate (Oriented Strand Board, oriented structure chipboard is a kind of synthesized wood material) 3, waterproof roll 5 forms.This roofing is that OSB plate 3 is directly screwed on light gauge cold-formed steel shape truss 1, and stress performance is poor; Between OSB plate and plate there is gap in overlap joint, and water resistance is poor; Need the glass wool 4 conduct insulations outside plus, heat insulation effect is bad.
Summary of the invention
Object of the present invention be exactly provide in order to overcome the defect that above-mentioned prior art exists that a kind of water resistance is good, stress performance is good, high insulating effect, simple installation light gauge cold-formed steel shape structure polyurethane sandwich steel plate roofing system efficiently.
Object of the present invention can be achieved through the following technical solutions:
A kind of light gauge cold-formed steel shape structure polyurethane sandwich steel plate roofing system, comprise gypsum plank and light gauge cold-formed steel shape truss, described light gauge cold-formed steel shape truss is located on gypsum plank, also comprise polyurethane sandwich steel plate, described polyurethane sandwich steel plate is fixed by screws on light gauge cold-formed steel shape truss.
Described polyurethane sandwich steel plate comprises double-layer plate and is filled in the polyurethane between double-layer plate.
When multiple polyurethane sandwich steel plate overlap joint, between adjacent polyurethane sandwich steel plate, adopt hidden discount overlap joint.
Compared with prior art, the present invention has the following advantages:
(1) between polyurethane sandwich steel plate of the present invention, adopt hidden discount overlap joint, overlap joint design closely, prevents the Seepage of rainwater effectively, and water resistance is good;
(2) polyurethane sandwich steel plate of the present invention is made up of double-layer plate composite polyurethane, has improved the bearing capacity of roof panel;
(3) existence of polyurethane has guaranteed the heat insulation effect of building;
(4) simple installation is quick, effectively cost-saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional Roof system;
Fig. 2 is structural representation of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 2, a kind of light gauge cold-formed steel shape structure polyurethane sandwich steel plate roofing system, comprise gypsum plank 2, light gauge cold-formed steel shape truss 1 and polyurethane sandwich steel plate 6, light gauge cold-formed steel shape truss 1 is located on gypsum plank 2, and polyurethane sandwich steel plate 6 is fixed on light gauge cold-formed steel shape truss 1 by hidden bolt-type.
Polyurethane sandwich steel plate 6 comprises double-layer plate and is filled in the polyurethane between double-layer plate.When multiple polyurethane sandwich steel plate overlap joint, between adjacent polyurethane sandwich steel plate, adopt hidden discount overlap joint.
The design of above-mentioned light gauge cold-formed steel shape structure polyurethane sandwich steel plate roofing system board face overlap joint closely, prevents the Seepage of rainwater effectively, and water resistance is good.Adopt the polyurethane sandwich steel plate of double-layer plate composite polyurethane formation, improved the bearing capacity of roof panel, the existence of polyurethane has simultaneously guaranteed the heat insulation effect of building.
