Problems solved by technology

However, for prefabricated structures, there are also disadvantages such as high component manufacturing cost, certain error in component size, weak component integrity and rigidity, and poor seismic effect of the structure.
[0003] CN201610303221.5 Assembled beam-column joints set through holes on the prefabricated beams, pass the connecting steel bars smaller than the diameter of the through holes through the through holes, and then pour HUPC in between, which requires higher accuracy of the reserved hole positions, and requires The size is accurate, otherwise it will not only increase the difficulty of construction, but even affect the structure. Moreover, when connecting, use the connecting steel bar to pass through the through hole on the precast column and lap the longitudinal bar on the precast beam, fix it with stirrups, and then pour concrete. , this structure uses stirrups to fix the joints, and the joints in this way are not strong enough
The connection between the prefabricated column and the prefabricated beam is provided with grooves for overlapping. This method also requires high dimensional accuracy of the grooves, and it is more troublesome to implement

Abstract

The invention belongs to the technical field of construction engineering and particularly relates to an L shaped prefabricated beam column joint which is mainly used for improving the anti-seismic property of a structure and comprises a prefabricated column and a prefabricated beam; the prefabricated column comprises a column body and a prefabricated column pouring connecting part; the prefabricated beam comprises a beam body and a prefabricated beam pouring connecting part; and the prefabricated column pouring connecting part and the prefabricated beam pouring connecting part are connected ina welding manner and are poured with concrete. Compared with the prior art, the L shaped prefabricated beam column joint is high in structural bearing capacity, large in rigidity and small in cross section, excellent in structural ductility and are more excellent in anti-seismic property. A combined structure is high in construction speed and short in construction period; before concrete pouring,profile steel forms a steel structure and has higher bearing capacity, so that a support does not need to be arranged, the construction speed is accelerated, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to an L-shaped prefabricated beam-column joint, which is mainly used to improve the anti-seismic performance of structures. Background technique [0002] With the demand for innovation in the construction market, construction is developing in the direction of high efficiency, speed, and quality. As a new architectural form, prefabricated buildings improve construction efficiency and shorten construction time on the basis of ensuring orderly management of on-site construction. cycle, and played a very important role in the control of construction quality. However, for prefabricated structures, there are also disadvantages such as high component manufacturing cost, certain error in component size, weak component integrity and rigidity, and poor seismic effect of the structure. [0003] CN201610303221.5 Assembled beam-column joints set through holes on the prefabricat...
