Description
Technical Field
The utility model belongs to the technical field of building and civil engineering, and relates to an energy-consumption and shock-absorption reinforced assembled beam column connecting node.
Background
At present, besides wider application of the prefabricated single-layer industrial factory building system, the engineering application of other prefabricated building systems is very few. The integrity of the prefabricated structure earthquake resistance and the specialized research of design construction management are insufficient, so that the technical economy is poor, and the prefabricated structure is a root cause for causing the prefabricated structure to be in a stagnation state for a long time.
Compared with the cast-in-situ structure, the assembled concrete structure has the advantages of short construction period, easy guarantee of component quality, standardization, finalization, industrial production and the like, and is greatly popularized. The research focus of the assembled frame structure is on the connection mode and the basic mechanical property of beam column joints, and the safety and the reliability of the assembled structure are required to be ensured. Through seismic hazard investigation of fabricated structures, prefabricated beams or columns are found to be relatively lightly damaged, and structural failure is mainly due to structural collapse caused by connection failure between structural components. Through research on the assembled beam column node, the bearing capacity of the assembled node is smaller than that of the cast-in-situ node, and if the rigidity of the beam column connecting node of the assembled structure is larger, the bearing capacity of the assembled structure is larger; and the cast-in-situ integral type node has larger displacement ductility, energy consumption capability and equivalent viscous damping coefficient and better earthquake resistance. Research also finds that the existing beam column node has the problems of complex design, complicated assembly type node fittings, difficult construction, higher engineering cost and the like.
