Description
Technical field
The utility model belongs to building structural element, particularly a kind of template is fixed in cold bending thin wall lattice configuration steel and the compound building unit of concrete on the cold bending thin wall lattice configuration steel skeleton.
Background technology
The primary structure member of current architecture configuration mainly with reinforced concrete member, includes but not limited to that template member and beam, post member and steel member are main.Reinforced concrete member and steel member, relatively independent substantially formation reinforced concrete structure system and steel structure system.Steel work and reinforced concrete structure are two relatively independent structural systems substantially, and shaped steel is difficult to realize combining with concrete.
Reinforcing bar in the reinforced concrete structural element can not can form skeleton to guarantee planform and working load requirement in the construction stage as the primary structure material at present; Must cooperate a large amount of templates and support could realize fluid concrete; Concrete surface after the cast, must cooperate surface layer to touch ash could be smooth; Reinforcing bar and template process can only be by manually realizing; Particularly wood consumption is huge.Reinforcing bar is generally only considered its tension effect in concrete structural system, and is difficult to bring into play the compressive property of steel, and the structural performance and the functional performance of steel all are not fully used.The reinforced concrete structure system, to concrete intensity and performance requirement strictness, this just must cooperate high strength cement and high strength aggregate to realize that because the huge construction weight that causes of concrete weight is big, the active strength efficient of structure is low.Dwelling house is the building of comprehensive wiring very dense, and comprehensive wiring is difficult to construct synchronously with agent structure, more be difficult to be implemented in the agent structure flexibly level and pass through, cause indoor bright dew pipeline too much, increase operation, increase cost, difficult quality guarantee, influence use with vertical.The node complexity of frame construction, safeguard the particularly overall performance weakness of masonry panel of body of wall, influence anti seismic efficiency.And forming the Liang Jiao and the post angle of indoor bright dew, influence is used.General structure of reinforced concrete cost, reinforcing bar processing, loss and form work engineering, heavy cost of labor is too high; Template causes a large amount of lumber consumptions.And these only to be the consumption of work progress produce not in all senses structure.
As the hot-rolled steel section in the steel reinforced concrete member,, must cooperate reinforcing bar or artificial surface layer to handle ability and concrete reliable connection, complex process, cost height owing to the cross section is big.And the area of structural steel is very big, and very difficult flexible combination becomes multiple cross-sectional configuration, generally only is used for the member that the structural column of highrise building and beam etc. bear linear load and point load.Enclosed structure also needs conventional method to solve.
Hot-rolled steel section member in the ordinary steel structure general only uses as beam that bears linear load and the post that bears point load.It is anticorrosion, fire prevention and stable, need carry out complicated structure processing and coating and handle and could realize.In civilian construction, high to the requirement condition of enclosed structure.
Cold-rolled forming section is generally C, U, Z, the shaped steel of real abdomen at present, because stability is relatively poor, generally is used for non-main force structure.The domestic standard prematurity still that is used to build low story dwelling, the technical system that also is not formed for building multilayer and high residential building.Abroad, cold-rolled forming section is mainly used in the construction low story dwelling, but its stability and fireproof performance need guarantee that anticorrosion problem generally needs galvanizing coating to realize with the dimension protecting plate with intensity and fire resistance.
Also has a kind of cold bending thin wall lattice configuration steel at present abroad.This cold bending thin wall lattice configuration steel has been realized the web of common C shaped steel is carried out continuous perforate, and guarantees that the bulk strength of shaped steel does not significantly weaken, and lateral stability is strengthened.And realized industrialization production in recent years abroad.This shaped steel has solved the problem of threading in structure, and overall stability is strengthened.The lattice light-gauge steel section, application abroad generally only is used for low-rise building in conjunction with the plug-in sheet material of safeguarding at present, does not also carry out rational the combination with concrete at present.
