The invention discloses a multi-layer prefabricated square steel tube concrete connecting beam. The multi-layer prefabricated square steel tube concrete connecting beam comprises a plurality of main beams which are sequentially superposed in a seamless mode, wherein each main beam comprises a square steel tube and concrete which is poured into the square steel tube; and two ends, in the length direction of each main beam, of each main beam extend into a shear wall. According to multi-layer prefabricated square steel tube concrete connecting beam provided by the embodiment of the invention, the plurality of main beams are sequentially superposed in the seamless mode, so that span height of the formed multi-layer prefabricated square steel tube concrete connecting beam is several times of that of a single connecting beam; besides, the main beams are formed in a mode of pouring concrete into the square steel tubes, so that the structural distortion ability can be improved, the connecting beam is guaranteed to have good ductile performance and the connecting beam is prevented from brittle shear failure. Besides, the main beams provided by the embodiment adopt a manner of prefabricated parts, so that assembly can be performed on the site, and therefore, the multi-layer prefabricated square steel tube concrete connecting beam has the advantages of high construction speed and controllable construction quality.
Description
technical field [0001] The invention relates to the technical field of structural engineering in civil engineering, in particular to a multi-layer prefabricated square steel tube concrete connecting beam. Background technique [0002] Coupling beams refer to beams connecting wall piers to wall piers in shear wall structures and frame-shear wall structures, that is, coupling beams refer to beams whose two ends are connected to shear wall piers in a plane. In the building structure, the coupling beam is an important energy-dissipating component in the shear wall or core tube structure system of high-rise buildings, and generally has the characteristics of small span and large cross-section. [0003] For structures in high-intensity areas, the use of ordinary reinforced concrete coupling beams is very easy to cause the shear-compression ratio to exceed the limit. Therefore, in order to improve the seismic performance of the coupling beam and increase the shear-compression rati...
