An anti-seismic frame structure composed of upright columns and connecting beams and its construction method

Abstract

The invention discloses an anti-seismic frame structure composed of upright columns and tie beams and a construction method thereof, belonging to the technical field of building structures, including upright columns, tie beams, trim panels and concrete. The upright columns include steel pipes, sprues, and L-shaped steel channel groups 1, through hole 1 and bolt hole 1, the connecting beam is fixed between the two columns by high-strength bolts, the connecting beam includes the main reinforcement of the beam, the stirrups of the beam, the shear reinforcement and the anchor plate, and the main reinforcement of the beam is located inside the connecting beam , the two ends of the main reinforcement of the beam are respectively connected with the through holes of the two adjacent columns, the hoops of the beam are hooped on the main reinforcement of the beam, two shear reinforcements form a group, and each group of shear reinforcements is cross-connected in pairs Between the main reinforcement of the beam, the anchor steel plate is fixedly welded at both ends of the inclined shear reinforcement and the main reinforcement of the beam. In a word, the invention has the advantages of high ductility, good anti-seismic performance, convenient construction and the like.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to an anti-seismic frame structure composed of upright columns and connecting beams and a construction method thereof. Background technique [0002] Frame structure refers to the structure composed of beams and columns connected by steel bars to form a load-bearing system, that is, the frame composed of beams and columns jointly resists horizontal loads and vertical loads that occur during use. The walls of the frame structure house are not load-bearing, and only play the role of enclosure and separation. Generally, prefabricated aerated concrete, expanded perlite, hollow bricks or porous bricks, pumice, vermiculite, ceramsite and other lightweight plates are used for masonry or assembly. made. [0003] The frame structure is also called frame structure. According to the number of spans, the frame of the house can be divided into single-span and multi-span;...
