Anti-seismic structure for reinforced concrete structure beam-column joint

Abstract

The invention discloses an anti-seismic structure for a reinforced concrete structure beam-column joint. The anti-seismic structure comprises a vertical column, a cross beam, a top fixing plate and a bottom fixing plate, wherein left and right grooves are connected to the two sides of the tops of the vertical column in an embedded mode, the bottoms of the left and right grooves are movably connected with the cross beam, the top of the cross beam are movably connected with the top fixing plate, the bottom of the cross beam are movably connected with the bottom fixing plate, a front groove and a rear groove are connected to the middle of the interior of the vertical column in an embedded mode, lap joint grooves are connected to the two sides of the vertical column in an embedded mode, two triangular blocks are arranged in the middle of each lap joint groove, the triangular blocks are symmetrically distributed up and down, misplug of other conventional structures is avoided through the arrangement, meanwhile, due to the triangular supporting effect of the triangular blocks, lap joint of the lap joint columns and the lap joint grooves is more stable and attached, the fixing plate wraps the periphery of the cross beam and is fixed through bolts, so that the situation that the cross beam cannot be fixed due to the fact that one position of the fixing plate is not fixed well is avoided, the fixing effect between the vertical column and the cross beam is improved through the fixing plate, and meanwhile practicability is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-seismic structure for beam-column joints of reinforced concrete structures. Background technique [0002] Reinforced concrete beams and columns are beams made of reinforced concrete materials. Reinforced concrete beams can be made as independent beams, or as integral beam-slab floors with slabs, or single-layer or multi-layer frames as a whole with columns, beams There are various forms, and it is the most basic load-bearing component in engineering structures such as housing construction and bridge construction, and has a wide range of applications. Among them, the most prominent one is the prefabricated concrete structure, which refers to the building structure composed of various components processed according to the standard size, and then transported to the site for direct splicing. Due to its short construction period, fast production speed and good en...
