Abstract
A novel steel-concrete composite beam without a steel beam upper flange comprises a reinforced concrete slab, a steel beam lower flange and a steel beam web plate, wherein one side of the steel beam web plate is a sawtooth edge, the sawtooth edge is formed by cutting a steel plate or an H-shaped steel web plate along a broken line, the sawtooth shape is an inverted trapezoid, a rectangle or other shapes, and the whole sawtooth extends into the reinforced concrete slab to form a shearing connecting piece of the composite beam. The steel beam upper flange, the single shear connector and the welding thereof are omitted, so that the steel consumption of the combined beam is saved, the quality of the shear connector is reliable, the manufacture and the construction and the installation are simple and convenient, the binding force with the concrete slab is large, and the manufacturing cost is lower than that of the common steel-concrete combined beam. The novel steel-concrete composite beam can be applied to roof beams of house buildings, crane beams, bridge span members of composite bridges and the like.
Description
Technical field
The present invention relates to a kind of compound beam,, belong to bridge and building supporting member scope more specifically to a kind of novel steel-concrete combination beam that is applied to bridge and industry and civilian construction floor system.
Background technology
Steel-concrete composite beam is combined girder steel and concrete slab stressed jointly by shearing connecting piece, compare with reinforced concrete beam, can reduce structure height, alleviate deadweight, and then reduce the sectional dimension and the foundation load of vertical supporting member, reduce construction formwork and support, easy construction.Compare with girder steel, then can reduce steel using amount, increase rigidity, improve stability, and reduce structure height, strengthen corrosion resistance and durability.In multi-rise building floor system and bridge bridge span structure, obtained using widely.The girder steel of existing steel-concrete composite beam is H shaped steel, i shaped steel and box-type section, yet studies show that, because the girder steel top flange is in close proximity to the cross section neutral axis, the stress of girder steel top flange was less when compound beam destroyed, its intensity to the compound section only plays a part seldom, its major function provides the stability of girder steel when constructing, and provides the position for welding shear connector.If with the cancellation of girder steel top flange, then compound beam is with more economical; For effective the combination and the rigidity and the intensity of compound beam that guarantees girder steel and concrete slab, must weld shear connector on the girder steel, thereby great amount of manpower, man-hour have been expended, the cost and the difficulty of construction of compound beam have been increased, simultaneously, because influenced by human factor bigger for welding quality, can not fully guarantee, thereby influence the security reliability of compound beam.
Summary of the invention
The objective of the invention is to solve above-mentioned the deficiencies in the prior art and problem, provide a kind of girder steel to have only bottom flange and web, utilized the novel compound beam of the serrated edge of steel beam web plate as shearing connecting piece, monomer-type shearing connecting piece and welding thereof have been saved, thereby the compound beam steel using amount is economized, the shearing connecting piece reliable in quality, making and construction and installation are easy, and are big with the adhesion of concrete slab, and cost is lower than adopting common steel-concrete composite beam.
The present invention is achieved by the following technical solutions:
A kind of steel-concrete composite beam of the present invention, comprise armored concrete slab, girder steel bottom flange and steel beam web plate, girder steel has only bottom flange and web in the described compound beam, on one side the web of girder steel is a toothed edge, whole sawtooth stretches into the shearing connecting piece that constitutes compound beam in the armored concrete slab.Described web toothed edge is formed along the broken line cutting by steel plate or H shaped steel web, and zigzag fashion is trapezoidal, rectangle or other shape; Described girder steel bottom flange and steel beam web plate are the bottom flange and the web of steel plate or H shaped steel.
Because adopt said structure, compared with prior art, steel-concrete composite beam of the present invention has following beneficial effect:
1, saves the girder steel top flange, saved steel, reduced the welding job amount of girder steel;
2, save monomer-type shearing connecting piece and welding thereof, saved material, artificial;
3, sawtooth has guaranteed the quality of connection of girder steel and armored concrete slab as shearing connecting piece, and big with the adhesion of armored concrete slab, anti-shear ability is strong;
4, because toothed edge is to be formed along the broken line cutting by steel plate or H shaped steel web, cutting forms two serrated edges, does not waste steel.
Because above characteristics, novel steel-concrete combination beam of the present invention can be used as the spanning member or the like of building roof beam, crane girder and the combined bridge of building construction.
