Abstract
The utility model relates to a steel-encased composite beam. The composite beam comprises a U-shaped steel-encased beam and a cast-in-place concrete floor arranged at the upper part of the U-shaped steel-encased beam, wherein the U-shaped steel-encased beam comprises a bottom edge and two vertical side edges, and the bottom edge and the two vertical side edges of the U-shaped steel-encased beam are made of a common low alloy steel plate and cold-formed thin-wall steel plates respectively. The section of the steel-encased composite beam is larger in rigidity and better in stability and seismic performance, most of the vertical shear force is born by filling concrete and a steel beam web together, and the vertical shear capacity of the composite beam is improved.
Description
Technical field
The utility model relates to a kind of compound beam, relates in particular to a kind of Covered with Angles compound beam.
Background technology
Shaped steel combination beam is by shear connector, shaped steel and concrete slab to be combined and cooperative a kind of novel form of structure, it has given full play to superior tensile property and the concrete compressive property of steel, in engineering, be more and more used widely, but there is following defect in shaped steel combination beam: being connected all the time between (1) concrete and shaped steel is not well solved, and slippage between the two and starting can not be ignored; (2) lateral stability in cross section is poor, in the time of torsion failure, and the anti-twisting property imbalance of girder steel and concrete frange plate, the anti-twisting property of girder steel can not get sufficient utilization; (3) compound beam limit bending bearing capacity is limited, and member span-depth radio is less, and fire resistance is also poor.
Summary of the invention
For overcoming the defect of above-mentioned shaped steel combination beam, the utility model provides a kind of Covered with Angles compound beam.
The technical solution adopted in the utility model is: a kind of Covered with Angles compound beam, described compound beam comprises U-shaped beams encased in steel hoops and is arranged at the cast-in-place concrete floor on U-shaped beams encased in steel hoops top, U-shaped beams encased in steel hoops comprises base and vertical dual-side, the base of U-shaped beams encased in steel hoops and vertically dual-side are made up of ordinary low-alloy steel plate and cold bending thin wall steel plate respectively, base is welded and fixed with vertical dual-side, vertically the top of dual-side arranges overhanging section of level, the first shearing resistance peg is set on the base of U-shaped beams encased in steel hoops, vertically in overhanging section of two levels of dual-side, the second shearing resistance peg is set, be horizontally disposed with multiple tie rods with the vertical dual-side of drawknot along the length direction of compound beam, stirrup is set in compound beam, stirrup is connected with the horizontal reinforcement colligation in floor, described horizontal reinforcement is assembling reinforcement net, stirrup and tie rod are fixedly connected with the first shearing resistance peg arranging on base, in the beam rib of described U-shaped beams encased in steel hoops and cast-in-place concrete floor position monobloc cast concrete form compound beam.
The advantage of this form of structure of the utility model is: the not impact of compressible type steel plate span of the span of (1) plate, can do greatlyr, and its rigidity of section is larger, stability and good seismic performance; (2) girder steel can just assemble in factory, and section form can be as required, makes various shapes; (3) tie rod of fill concrete and layout has been strengthened the globality of beam, rigidity and the stability of beam are strengthened, and the longitudinal shear for opposing plate and Liang Jiaojiemianchu has played certain effect, thereby can reduce the setting of stiffening rib and longitudinal shear resistance connector; (4), owing to having filled concrete in U-shaped beams encased in steel hoops, make the most of vertical shear of beam by fill concrete and steel beam web plate shared, so fill concrete has strengthened the vertical shear-carrying capacity of compound beam.
