Anti-vibration connecting device for fabricated concrete superposed beam and steel pipe column

Abstract

The invention discloses an anti-vibration connecting device for a fabricated concrete superposed beam and a steel pipe column. The anti-vibration connecting device comprises a box body, one side and the top side of the box body are provided with openings, the other side of the box body is fixedly connected with the periphery of the steel pipe column, a groove is formed in the bottom of the box body, a baffle is movably installed in the groove, the bottom side of the baffle is connected with the bottom side of the groove through a plurality of first springs, through grooves corresponding to inserting blocks are formed in the bottom side of supporting plates, the bottom sides, the left sides and the right sides of the through grooves communicate with the outside, the inserting blocks can move left and right in the corresponding through grooves, and the distances between the top sides and the bottom sides of the through grooves are gradually increased from left to right. The connecting device is simple in structure and ingenious in conception, can guide and position the superposed beam during assembling, facilitates rapid mounting of the superposed beam, is provided with the supporting plates, enables reinforcing steel bars at the end of the superposed beam to be evenly distributed in a reinforcing steel bar frame, enables the reinforcing steel bars of the superposed beam to be connected with the reinforcing steel bar frame, accordingly improves the anti-seismic effect, can meet market requirements and is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of prefabricated building structures, in particular to an anti-seismic connecting device for prefabricated concrete composite beams and steel pipe columns. Background technique [0002] Due to its excellent performance characteristics, steel pipe columns are widely used in buildings, especially some high-rise buildings. The combination of reinforced concrete composite beams and steel pipe columns meets the inherent requirements of "building industrialization" prefabrication; existing composite beams and steel pipe columns When the columns are connected, the steel bars at the ends of the composite beams are inserted into the connection part of the steel frame around the outer circumference of the steel pipe column, and then the concrete is poured. However, the reinforcement of the composite beams is inserted into the steel frame and then scattered, and the stress they bear cannot be concentrated, resulting in The struc...

[0002] Due to its excellent performance characteristics, steel pipe columns are widely used in buildings, especially some high-rise buildings. The combination of reinforced concrete composite beams and steel pipe columns meets the inherent requirements of "building industrialization" prefabrication; existing composite beams and steel pipe columns When the columns are connected, the steel bars at the ends of the composite beams are inserted into the connection part of the steel frame around the outer circumference of the steel pipe column, and then the concrete is poured. However, the reinforcement of the composite beams is inserted into the steel frame and then scattered, and the stress they bear cannot be concentrated, resulting in The structural strength is reduced, and the composite beam and the steel frame are only connected by concrete pouring, which is prone to loosening when subjected to vibration, and the reinforcement of the composite beam is easy to move in the concrete, which cannot meet the actual needs. Therefore, we invented a A prefabricated concrete composite beam and steel pipe column seismic connection device
