Compound beam reasonable stress, gives full play to the superiority of concrete floor Compressive Performance and girder steel examining tensile behavior, effectively saves material, improves the performance of superstructure.In routine building, girder steel cross section can very little, and the top flange width of H profile steel beam and thickness are less than bottom flange, and can provide good flooring rigidity.
When girder steel span is comparatively large, superstructure load is larger, the situations such as such as warehouse logistics building, superstructure need preloading, traveling vehicle, and the permanent live load of flooring is very large, larger to the bearing capacity and stiffness demand of superstructure.If adopt traditional way, in order to meet structural performance requirements, girder steel cross section needs to strengthen, often economical not.
Along with the fast development of internet, the demand of electric business's logistics class building is very vigorous, and the quality of superstructure issue handling can have influence on structural performance and the cost of building, is a current active demand.
Utility model content
Existing greatly across the stressed and rigidity requirement of heavy superstructure compound beam in order to overcome, coordinate the exploitation that electric business's logistics class is built, the utility model proposes a kind of Steel concrete compound beam structure, the demand of structural strength and rigidity can be met, can be applicable to large across the superstructure in heavy load situation, simple structure, power transmission be clear and definite, convenient and quick construction.
The technical solution adopted in the utility model is:
The utility model comprises H profile steel beam, shear connector, floorslab concrete, girder steel side concrete, floor upper reinforcement, floor lower rebar, waist muscle and steel tie; Floor upper reinforcement passes through above H profile steel beam, above H profile steel beam and between floor upper reinforcement and the both sides of H profile steel beam of concreting, the floorslab concrete above formation H profile steel beam and between floor upper reinforcement and the girder steel side concrete of H profile steel web both sides; The upper surface of H profile steel beam top flange and the upper surface of H profile steel lower flange of girder edge are all welded with the shear connector for Transfer of Shear, the floor lower rebar of bending is provided with between the H profile steel beam top flange and H profile steel lower flange of girder edge of H profile steel web both sides, floor lower rebar bends along the edge of H profile steel web and upper bottom flange, floor lower rebar forms reinforcing cage by waist muscle and steel tie, and waist muscle and steel tie are passed through by the perforate of the web of H profile steel beam.
Described shear connector is peg or angle steel.
The width of described H profile steel beam top flange is less than the width of H profile steel lower flange of girder edge.
The concrete cross section of described H profile steel beam both sides is the inverted trapezoidal shape that upper end is large, lower end is little.
The described concrete section in girder steel side is rectangle.
The described concrete section in girder steel side is the inverted trapezoidal that upper end is large, lower end is little.
The beneficial effects of the utility model are:
The utility model node can be used for H profile steel beam and concrete combination beam, can meet the demand of structural strength and rigidity, can be applicable to large across the superstructure in heavy load situation, and simple structure, power transmission are clear and definite, convenient and quick construction; Can be widely used in that girder steel span is comparatively large, load is comparatively large and in the higher superstructure of floor rigidness requirement.
