Rear connecting device and method for solid-web steel beam and concrete beam

Abstract

The invention provides a rear connecting device and method for a solid-web steel beam and a concrete beam. The rear connecting device comprises a first side plate, a cover plate, a second side plate and an anchor bolt, the first side plate and the second side plate are oppositely arranged at the opposite ends of the cover plate and are movably connected with the cover plate, and the anchor bolt is movably connected with the first side plate and the second side plate. The rear connecting device further comprises a first side plate reinforcing plate, a cover plate reinforcing plate and a second side plate reinforcing plate, the first side plate reinforcing plate is arranged on the outer side of the first side plate, the cover plate reinforcing plate is arranged on the outer side of the cover plate, and the second side plate reinforcing plate is arranged on the outer side of the second side plate. The connecting device has the beneficial effects that the anchoring stability of the connecting device can be improved, operation and maintenance are convenient, and the engineering cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of installation of building steel structure beams, and in particular relates to a rear connection device and method for solid-web steel beams and concrete beams. Background technique [0002] With the continuous development of urban construction, the number of existing building renovation projects is increasing. In actual engineering, in order to consider the connection requirements of steel beams in the later stage, or to change the usage in practical applications, steel plates cannot be pre-embedded in concrete beams in advance, and the connection requirements of steel beams cannot be met. [0003] In the prior art, the solid web steel beam is placed on the upper part of the concrete beam, and when the connection node is located at the end of the beam, the steel bars at the upper part of the beam end are generally densely arranged, and the rear anchor bolts are likely to collide with the steel bars in the ...

In actual engineering, in order to consider the connection requirements of steel beams in the later stage, or to change the usage in practical applications, steel plates cannot be pre-embedded in concrete beams in advance, which cannot meet the connection requirements of steel beams

[0003] In the prior art, the solid web steel beam is placed on the upper part of the concrete beam, and when the connection node is located at the end of the beam, the steel bars at the upper part of the beam end are generally densely arranged, and the rear anchor bolts are likely to collide with the steel bars in the concrete beam, resulting in the failure of the rear anchor bolts to Meet the design requirements, there are technical problems that the anchor bolts are easy to loosen, the connecting device is easy to fall off, and the project cost is high
