Example Embodiment

[0019] The present invention will be further described below in conjunction with specific embodiments and drawings:

[0020] Such as figure 1 As shown, a hybrid shear connector includes a channel steel connector 1 and a bent rebar connector 2. The channel steel connector 1 and the bent rebar connector 2 are arranged in the floor, and the channel steel connector 1 and The bent rebar connectors 2 are arranged alternately on the steel beams 3. The channel steel connectors 1 should be arranged at the beam ends. The webs of the channel steel connectors 1 are provided with reserved holes, and the longitudinal steel bars in the floor slab The steel bars 4 pass through the reserved holes.

[0021] An additional transverse steel bar 5 is added to the bent rebar connector, and is fastened to the bent rebar connector 2.

[0022] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from th...

Abstract

The invention discloses a mixed shear connector which comprises channel steel connectors and bent-up steel bar connectors, wherein the channel steel connectors and the bent-up steel bar connectors are arranged in a floor slab and distributed on a steel beam alternately; the channel steel connectors are suitable for being arranged at the beam end; preformed holes are formed in ventral plates of the channel steel connectors; and reinforcement bars in reinforced nets in the floor slab penetrate through the preformed holes. According to the mixed shear connector, the channel steel connectors and the bent-up steel bar connectors are distributed on the steel beam at intervals, so that joint shear of the bent-up steel bar connectors and the channel steel connectors is realized, cooperative work of the steel beam and the concrete floor slab is guaranteed, and the structure bearing capacity is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering building structures, in particular to a hybrid shear connector. Background technique [0002] The stud is a flexible connector, the force is not directional, the volume is small, the layout is flexible and convenient, but the shear bearing capacity is not large, the bending stiffness is small, the pressure bearing surface is small, the stress concentration at the root is large, excessive welding, resulting in excessive residual stress. Although it has good deformation ability, but the bearing capacity is low. Moreover, special welding machines and ceramic rings are required, and the construction process is relatively complicated. [0003] When conditions permit, most of the stud connectors are used, and the low bearing capacity makes it necessary to use a large number of studs when resisting shear. Although the actual bearing capacity of studs is much larger than the bearing capacity ...
