Steel-concrete mixing type anti-shearing connecting piece

Abstract

The invention provides a steel-concrete mixing type anti-shearing connecting piece which is applicable to connecting a wave-shaped steel web plate and a concrete top plate. The top of the wave-shaped steel web plate is provided with a hole; the upper part of the hole is respectively welded with one or more combined steel bars along the vertical direction of the two sides of the wave-shaped steel web plate; at the position of a combined face of the wave-shaped steel web plate and the concrete top plate, one horizontal frange plate which is in convex-concave complementation and tight adhesion with the wave-shaped steel web plate is respectively arranged at each one of the two sides of the wave-shaped steel web plate in the vertical direction; the frange plate is provided with a plurality of vertical welding nails; a connection structure above the frange plate stretches into the reinforced concrete top plate connected with the frange plate; and a transverse steel bar in the concrete top plate penetrates through the hole on the wave-shaped steel web plate, and the concrete of the wave-shaped steel web plate is poured. The steel-concrete mixing type anti-shearing connecting piece has the characteristics of an imbedded anti-shearing connecting piece and a frange type anti-shearing connecting piece; steel products are saved, the machining is convenient, the construction is convenient and the anti-shearing strength is high; the strength, the rigidity and the durability of a connecting part are better; and the integrity of the combined part is good, and the social and economic benefits are good.

Description

technical field [0001] The invention belongs to the technical field of shear connectors of steel-concrete composite structures, and in particular relates to a steel-concrete hybrid shear connector. Suitable for connection between corrugated steel web and concrete roof. Background technique [0002] The structure of the joint between the corrugated steel web and the concrete roof and floor is directly related to the bearing capacity of the bridge, and is one of the key parts of the corrugated steel web girder. The joint structure needs to be able to resist the horizontal shear force between the steel and concrete materials in the structure, so as to ensure that when the combined structure is stressed, there will be no relative displacement between the two different materials. [0003] At present, there are many types of shear connectors used in steel-concrete composite beams, and the commonly used ones are mainly embedded type and flange type. The embedded type is to op...

Problems solved by technology

However, the amount of double-holed steel plate steel used in this connector is large, and the longitudinally perforated steel plate divides the already small volume of concrete in the top plate at the joint twice, which is not conducive to the overall force of the concrete at the joint

And the construction is more complex than embedded connectors
