Description
Technical field
The present invention relates to a kind of structural thin-walled clod wash member.
Background technology
Along with scientific and technical development, various modern buildings be presented in people in face of, as glass wall, metallic object packing etc.Have again at present many novel buildings to adopt the building of Roof system, the especially steel work of metal construction, its Roof system also adopts the Roof system of metal construction naturally.Composite metal Roof system is applied more and more extensive in the buildings such as all types of industries, physical culture, amusement, exhibition hall, retail supermarket.Metal Roof system need to be used metal roofing board and metal construction base plate isostructuralism thin-walled clod wash member.In addition, in various building systems, also generally use at present metal wall panel, as side fascia, interior wall partition etc.In recent years, along with the development of highrise building, building curtain wall is day by day promoted and applies.No matter be curtain wall or metal curtain wall, all need to adopt supporting member, as connection supporting and the structural framing of curtain wall slab.In curtain wall system, generally use at present aluminium alloys supporting member, in addition, in metal curtain wall, generally use aluminum alloy curtain walls.Above-mentioned metal roofing board, metal construction base plate, metal wall panel, metal curtain wall and structural supporting member thereof generally belong to structural clod wash member, and the present invention's alleged " thin-walled " refers to the above-mentioned member that is not more than 12mm wall thickness.
Said structure clod wash member is as the structural element of metal building, the intensity of himself has strict requirement, in addition its refractoriness is also strictly regulated, once breaking out of fire, hardware can with naked light and high temperature air thermal contact conductance, steel work can intensity sharply decline along with the rising of temperature, yield strength reduces, modulus of elasticity obviously declines, and then can affect temperature deformation and stress distribution subsequently, the structural stability of final impact building, causes it can not reach design life, has a strong impact on safety and the application life of building.The non-refractory of aluminium extruded sections own, therefore fire line is poor, and at present a lot of structural ordinary carbon steel clod wash members processing of also not preventing fires, and therefore has fire safety hidden danger, is difficult to meet fire protection requirement.In order to reach fire-resistant requirement, generally adopt fireproof paint coating in addition flameproof protection of member, but this fireproof paint outward appearance is ugly, impact building attractive in appearance, and also maintainability is poor; In addition, said structure clod wash member also needs to possess long-term etch-proof performance, generally paints to realize anticorrosion resistance to marquis's requirement at the external surface of metal especially steel at present, but maintenance and construction are all cumbersome, or adopts galvanized sheet, but its cost is higher; Even if carry out anticorrosion weather-proof processing, existing member also cannot reach fire-resistant requirement.Along with the raising of awareness of safety, the requirement of metal building safety is more and more higher, and the structural thin-walled clod wash member that simultaneously possesses fire prevention and weather resisteant energy becomes the direction of development.
