Problems solved by technology

The connection between the steel beam and the concrete slab and the connection between the concrete slab and the concrete slab need to pour concrete on site. There are a lot of steel bar binding, connection work and concrete pouring work. The construction period is long, and the pollution of the environment caused by site pouring and curing of concrete is unavoidable. Once the concrete slab and the steel beam are connected as a whole, they cannot be disassembled, and once the adjacent concrete slabs are connected as a whole, they cannot be disassembled, making it difficult to reuse

Embodiment Construction

[0019] The so-called dry connection in the present invention refers to the connection form between the concrete member and the steel member or the connection between the concrete member and the concrete member by mechanical means (such as welding, bolt connection, tenon connection) as an integral structure. The cast-in-place concrete realizes the connection corresponding to the concept of "wet connection".

[0020] Such as Figure 1-5 Shown, a kind of dry-type connection prefabricated assembled steel-concrete composite beam comprises a steel beam, a concrete slab made of steel bars and concrete, a steel plate connector made of steel plates, shear connectors and connecting rods, and a steel plate connector 100 ( See figure 2 ) The steel plate 101 in ) is arranged horizontally, the steel shear connector 102 is vertically welded on the upper surface, and the connecting rod 103 is vertically welded on the lower surface. It also includes a pair of inter-plate connectors consisti...

Abstract

The invention discloses a dry-connected prefabricated assembled steel-concrete composite beam. The dry-connected prefabricated assembled steel-concrete composite beam comprises a concrete slab, a steel plate connector and a steel beam, and further comprises a pair of inter-plate connecting components consisting of an upper connecting plate, a lower connecting plate, a horizontal connecting plate, a triangular stiffening steel plate, first shear connecting components and a second shear connecting components respectively, wherein two ends of transversely-preset steel bars in the concrete slab are connected and fixed to the pair of inter-plate connecting components which are correspondingly placed respectively; shear connecting components in the steel plate connector are placed below the transversely-preset steel bars in the concrete slab in a centering manner, and a steel plate is parallel to the horizontal connecting plates in the inter-plate connecting components; concrete is poured, and the concrete connects the preset steel bars in the concrete slab, the inter-plate connecting components and the shear connecting components in the steel plate connector into the concrete slab in an enwrapping manner to form a steel-concrete prefabricated assembled component; the steel-concrete prefabricated assembled component is in dry connection with the steel beam to form the steel-concrete composite beam.

Description

technical field [0001] The invention relates to a steel-concrete composite beam, in particular to a dry-type connected prefabricated assembled steel-concrete composite beam. Background technique [0002] Steel-concrete composite beam is a new type of structure developed on the basis of steel structure and concrete structure. It sets shear connectors between the lower steel beam and the upper concrete flange (concrete slab) to resist the lifting and relative sliding of the two at the interface, so that the steel beam and the concrete slab work together to become A beam that works as a whole. In the steel-concrete composite beam, the existing connection method between the steel beam and the concrete slab is: one end of the shear connector is welded to the steel beam on site, and the rest of the shear connector is poured into the concrete slab, so that the steel beam Connected to the concrete slab as a whole. Adjacent concrete slabs are joined by wet joints of cast-in-place ...
