A Double Shear Plate Transfer Beam-Column Joint

Abstract

The invention discloses a double shearing resistant plate transformation beam-column joint which comprises transformation column and concrete transformation beams. A pair of parallel shearing resistant steel plates are vertically arranged at the beam end of each concrete transformation beam along the length direction of the concrete transformation beam and mutually connected at the beam-column joint of the concrete transformation beam and the corresponding transformation column in a penetrating manner. The shearing resistant steel plates are additionally arranged at the ends of the concrete transformation beams, the shearing capacity of the sections of the transformation beams is improved, and requirements of the shear-compression ratio stipulated by specifications are met. Compared with conventional methods such as enlarging beam sections and concrete strength or using profile steel concrete sections, the use ratio of building space can be increased, structural weight is reduced, earthquake effect is decreased, construction cost is reduced, construction is simple, construction quality is ensured, and construction period cannot be affected.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a transfer beam-column joint with double shear slabs, which is used in a transfer structure, and is especially suitable for a transfer structure in which a shear wall is arranged on the transfer beam. Background technique [0002] In recent years, with the rapid development of high-rise buildings, buildings are developing in a comprehensive direction with complex shapes and diverse functions, so the corresponding structural forms of high-rise buildings are also complex and diverse. This often requires that the upper floors of the building be arranged with residences and hotels in terms of use function, the middle floors be used as office rooms, and the lower floors are used as shops, restaurants and cultural and entertainment facilities. Floors with different uses require bays of different sizes and adopt different structural forms. Specifically, the building requires mor...

Problems solved by technology

[0005] (1) Increasing the beam section will reduce the headroom of the large space at the bottom, which will affect the use of building functions, and the self-weight will increase, the absorbed seismic force will increase, and the seismic effect will be large. In addition, for some frame beams, the reinforced steel bars at the end tend to be For structural reinforcement, increasing the beam section will undoubtedly increase the stress reinforcement of the frame support beam, resulting in waste of structural reinforcement and increasing construction costs

[0006] ⑵Using high-grade concrete grades for construction, because it is difficult to achieve high-grade concrete grades during actual construction, the construction quality is difficult to guarantee

[0007] (3) Steel concrete beams are used, the construction process is relatively complicated, the construction period is long, and the professional requirements of the construction team are relatively high
