Hanging structure for concrete beam and construction method of hanging structure

Abstract

The invention discloses a hanging structure for a concrete beam. The hanging structure for the concrete beam comprises the concrete beam, a top plate, connecting plates, a bottom plate and a hanging piece; the top plate is arranged on the top face of the concrete beam, the connecting plates are arranged on the two opposite side faces of the concrete beam in the width direction, and one ends of theconnecting plates in the length directions of the connecting plates are connected with the top plate; and the bottom plate is connected with the connecting plates, located below the concrete beam andused for bearing loads and transmitting the loads to the top plate through the connecting plates, and the hanging piece is connected with the bottom plate. According to the hanging structure for theconcrete beam, the maximum load allowed to be hung by the hanging structure for the concrete beam is effectively increased, and the numerical value of the maximum load allowed to be hung by the hanging structure can be accurately calculated, so that the potential safety hazard that the concrete beam is damaged due to overlarge stress is eliminated.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a concrete beam hanging structure and a construction method thereof. Background technique [0002] Concrete beams come in a variety of forms, and are the most basic load-bearing components in engineering structures such as housing construction and bridge construction, with a wide range of applications. In the related technology, the hanging structure under the concrete beam, such as hooks, embedded parts, bolts, etc., generally adopts the method of pre-embedding the hanging bars inside the concrete beam, and transfers the load of the hanging point of the beam to the top of the concrete beam, increasing the concrete beam. The maximum load allowed to be suspended. [0003] Due to later use, renovation and other reasons, it is often necessary to add lifting points under the existing concrete beams. However, since it is impossible to bury the hanging bars, the only met...

Problems solved by technology

[0003] Due to later use, renovation and other reasons, it is often necessary to add lifting points under the existing concrete beams. However, since it is impossible to bury the hanging bars, the only method is to install post-anchor bolts at the bottom of the concrete beams. The post-anchor anchor bolts and concrete The connection part of the beam is limited to the middle and lower part of the beam, so the load cannot be transmitted to the top of the concrete beam, and local tensile damage is very easy to occur, posing a safety hazard
