Bearing-shearing connector

Abstract

The invention discloses a bearing-shearing connector. The bearing-shearing connector is used for connecting a steel beam and a precast concrete plank, the steel beam and the precast concrete plank areused for forming an integrally forced steel-precast concrete composite beam; bearing-shearing connector is composed of two shearing plates and two bearing plates; the steel beam is provided with a plurality of bearing-shearing connectors, the multiple bearing-shearing connectors are arranged in the axial direction of the steel beam according to requirements of bearing capacities. The bearing-shearing connector has the beneficial effects that the bearing-shearing connector can ensure the effective connection of the steel beam and the precast concrete plank, the size of a reserved hole of the precast concrete plank is reduced so that weakening on the precast concrete plank is reduced, the manufacturing difficulty of the precast concrete plank is reduced, and the amount of work on the construction site is reduced.

Description

technical field [0001] The invention relates to a connection technology between a steel component and a prefabricated concrete component, in particular to a pressure-shear type connection piece. Background technique [0002] Compared with the steel-concrete structure using cast-in-place concrete, the steel-concrete structure using precast concrete has the advantages of fast construction speed, less on-site operations, and stable and controllable quality; in the prior art, steel-precast concrete composite beams are a kind of In a typical steel-concrete structure using precast concrete, one of the important factors determining the mechanical properties of steel-precast concrete composite beams is the effectiveness of the connection between the steel beam and the precast concrete slab; A common connection method is to set a large number of studs on the steel beam, and set up reserved holes corresponding to the studs on the precast concrete slab. During construction, the studs a...

[0002] Compared with the steel-concrete structure using cast-in-place concrete, the steel-concrete structure using precast concrete has the advantages of fast construction speed, less on-site operations, and stable and controllable quality; in the prior art, steel-precast concrete composite beams are a kind of In a typical steel-concrete structure using precast concrete, one of the important factors determining the mechanical properties of steel-precast concrete composite beams is the effectiveness of the connection between the steel beam and the precast concrete slab; A common connection method is to set a large number of studs on the steel beam, and set up reserved holes corresponding to the studs on the precast concrete slab. During construction, the studs are placed one by one. Insert it into the reserved hole, and then pour concrete in the reserved hole to realize the connection between the steel beam and the precast concrete slab. Using this connection method requires setting a larger reserved hole, which will significantly weaken the concrete structure. Therefore, it is necessary to make the prefabricated The steel bars in the concrete slab remain continuous at the reserved holes, which brings great inconvenience to the production of precast concrete slabs

Although the traditional section steel connectors occupy less space than the clustered stud connectors, their deformation capacity is limited, and the final failure state is brittle, which is usually not accepted in engineering
