Abstract

The invention discloses a detachable steel-concrete composite beam adopting conical nut and bolt connectors. The detachable steel-concrete composite beam comprises the bolt shear force connectors, a steel beam and precast concrete slabs. According to the detachable steel-concrete composite beam, the prefabricating rate of components is increased, site construction wet operation can be reduced, andthus pollution caused by construction flying dust to the atmospheric environment is avoided; shear surface areas of the shear force connectors at the steel-concrete interface can be effectively enlarged through conical hexagonal locking nuts, and the risk that roots of the shear force connectors are shorn off is lowered; the bonding effect between grout and the precast concrete slabs can be enhanced through corrugated pipes; dismantling and repairing are convenient; and the components can be recycled, generation of building waste is reduced to a certain extent, and resources are saved.

Description

technical field [0001] The invention relates to a detachable steel-concrete composite beam, in particular to a detachable steel-concrete composite beam using conical hexagonal locking nut bolt connectors. Background technique [0002] For a long time, most of the buildings built use the construction method of cast-in-place concrete. However, during the construction period of this kind of building, due to more wet work, it will generate a lot of smoke and dust, which will affect the air quality; A large amount of construction waste will be produced, which will affect the city appearance. [0003] In this context, in order to replace the previous cast-in-place buildings, engineers and technicians have developed various detachable steel-concrete composite beams. The characteristics of these steel-concrete composite beams are: (1) they are all connected by bolted joints, which is convenient for disassembly; (2) the components can be recycled and easy to repair; (3) the construc...
