Abstract
The utility model relates to a novel steel-concrete composite beam applied to bridges and industrial and civil building floor systems, which belongs to the field of bridges and building supporting members, and the composite beam shearing connecting piece of the utility model has reliable quality, simple and convenient manufacture, construction and installation and low cost; the novel steel-concrete composite beam comprises a reinforced concrete slab, a steel beam lower flange, a steel beam upper flange and a steel beam web plate, wherein one side of the steel beam web plate is a sawtooth edge, sawteeth extend out of the steel beam upper flange, and the whole sawteeth extend into the upper reinforced concrete slab to form a shearing connecting piece of the composite beam.
Description
Technical field
The utility model relates to a kind of compound beam, more specifically to a kind of new shaped steel-concrete combination beam that is applied to bridge and industry and civilian construction floor system, belongs to bridge and building supporting member scope.
Background technology
Steel-concrete combination 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, corrosion resistance and durability are strengthened.In multistory building floor system and bridge bridge span structure, obtained using widely.The shearing connecting piece of existing steel-concrete combination beam all adopts monomer-type, mainly contain socket cap weldering nail connector, the channel-section steel connector, forms such as bent-up bar connector, for effective the combination and the intensity of compound beam that guarantees steel and concrete slab, need to arrange several on the every meter long girder steel, tens even tens shearing connecting pieces, these connectors must weld with girder steel, thereby expended great amount of manpower, man-hour, the cost and the difficulty of construction of compound beam have been increased, simultaneously, because it is bigger that welding quality is influenced by human factor, can not fully guarantee, thereby influence the security reliability of compound beam.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art and problem, and a kind of new shaped steel-concrete combination beam is provided, compound beam shearing connecting piece reliable in quality of the present utility model, and making and construction and installation are easy, and cost is low.
The utility model is achieved through the following technical solutions:
A kind of new shaped steel-concrete combination beam of the present utility model, comprise armored concrete slab, girder steel bottom flange, girder steel top flange and steel beam web plate, described steel beam web plate is toothed edge on one side, sawtooth stretches out the girder steel top flange, and whole sawtooth stretches into the shearing connecting piece that constitutes compound beam in the top reinforcement 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 for falling trapezoidal or rectangle, and preferably isosceles trapezoid or chamfer are trapezoidal; 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, new shaped steel-concrete combination beam compared with prior art of the present utility model has following beneficial effect:
1, saves monomer-type shearing connecting piece and welding thereof, saved material, artificial;
2, because toothed edge is that steel plate or H shaped steel web are formed along the broken line cutting, cutting forms two serrated edges, does not waste steel;
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;
Because above characteristics, but the new shaped steel of the present utility model-building roof beam of concrete combination beam building construction, crane girder also can be used as spanning member of combined bridge or the like.
