Description

U-shaped steel concrete combination beam
Technical field
The utility model relates to one and cuts section bar, and relates in particular to a kind of U-shaped steel concrete combination beam, is applied to structure of steel structure building engineering field.
Background technology
Reinforced concrete beam is traditional main bearing member of building construction, have cross section large, from features such as great and long construction periods; Steel structure girder has that intensity is high, anti-seismic performance good, from features such as heavy and light, reusable edible, easy constructions, but also there is the shortcomings such as fireproof performance is poor, poor corrosion resistance; Steel reinforced concrete compound beam can be brought into play steel work and the concrete structure advantage of material separately, under steel using amount same case, improve the intensity of member, improve the ductility of member, the anti-seismic performance, fire prevention and the decay resistance that have strengthened structure, be widely used; But the cross section of steel reinforced concrete compound beam is large, the key of long construction period affects operation: formwork, assembling reinforcement, still effectively do not solved.
Utility model content
The utility model is mainly to solve the deficiencies in the prior art, a kind of compact conformation is provided, efficiently solve the factor that the on-the-spot formwork of reinforced concrete beam and assembling reinforcement have a strong impact on construction period and construction costs, relatively there is with conventional steel structural concrete beam the component strength of raising, improve component ductility, strengthen structural seismic performance, the better advantage such as fire resistance, relatively have with girder with rolled steel section en cased in concrete and reduce sectional dimension of members, reduce difficulty of construction, alleviate the U-shaped steel concrete combination beam of the advantages such as dead load.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of U-shaped steel concrete combination beam, comprise base plate and concrete beam, the two side ends on described base plate top is respectively equipped with web, the inwall of described web and the top of base plate are respectively equipped with equally distributed lateral stiffening plate and shearing resistance peg, the left end on the top of described web and right-hand member are respectively equipped with abutment segment fluting top board, between two abutment segment fluting top boards, be provided with the equally distributed batten plate that longitudinally adds, the outer wall of described web is provided with support bracket, the upper end of described web, abutment segment fluting top board and longitudinally add batten plate and be inserted in concrete beam, described base plate, web, abutment segment fluting top board and longitudinally add batten plate and form the cavity that is in the milk, in described grouting cavity, be provided with concrete.
As preferably, in described concrete beam, be provided with transverse reinforcement net, in described grouting cavity, be provided with the longitudinal reinforcement net fixing with transverse reinforcement net, after the splicing of described transverse reinforcement net and longitudinal reinforcement net, be " T " shape and distribute, between described the abutment segment fluting two side ends of top board 6 and the top of web 3, longitudinally add between the top of batten plate 7 and web 3 and be respectively equipped with and laterally add batten plate 14.
As preferably, locate mutually the described top of support bracket and the bottom of concrete beam, and the top of described support bracket is provided with the shear connector extending in concrete beam.
Adopt penetration welding to be connected with steel column bracket, do not need to arrange beam support shuttering, after beam column has connected, directly can lay floor support plate and floor steel bar, then carry out concrete pouring construction, work progress is convenient, easily operation.
In the time that beam span is large or case bay is larger, can adopt temporary supporting to support beam, complete and reach after design strength in concreting, can remove temporary supporting.
Therefore, U-shaped steel concrete combination beam of the present utility model, compact conformation, can form batch production, assemblingization and mechanical matching processing, and crudy is guaranteed, the construction period can accelerate, site operation is easy, assemblingization degree is high.
