Crisscross section total-prefabricated-type anti-buckling supporting member

Abstract

The invention discloses a crisscross section total-prefabricated-type anti-buckling supporting member. The crisscross section total-prefabricated-type anti-buckling supporting member comprises a crosscore member located at the center and four constraint square steel tube assemblies which are correspondingly arranged in the four right angle corners of the cross core member to form a peripheral constraint unit, the edges of every two adjacent constraint square steel tube assemblies are fixedly connected with a wing plate of the cross core member clamped between the two adjacent constraint square steel tube assemblies through a bolt assembly, and an X-shaped steel internal bracing is embedded in the tube of each constraint square steel tube assembly. According to the crisscross section total-prefabricated-type anti-buckling supporting member, the field assembly of all steel members is adopted, the construction is convenient, the manufacturing precision is easy to control, large tonnage buckling proof supporting can be improved through the arrangement of cross double cores, the precision control between a peripheral restraint member and a core steel plate is more convenient and concise, field installation is facilitated, all steel members can be manufactured in a factory, and the processing precision is easy to control; and the ductility performance of the member is obviously improved, the energy consumption capacity is greatly improved, and the seismic performance is improved.

Description

technical field [0001] The invention relates to an anti-buckling support in vibration control of structural engineering. In particular, it relates to a cross-section fully assembled anti-buckling support member. Background technique [0002] The anti-buckling brace is a new type of lateral force-resistant member, which has the advantages of ordinary braces and dampers, and has the function of energy dissipation and shock absorption in the seismic design of structures. After the Northridge earthquake in the United States in 1994 and the Hanshin earthquake in Japan in 1995, Japan, the United States and other countries conducted in-depth research on it, and the research on buckling-resistant braces in my country has gradually matured. Under the action of small earthquakes, the buckling-resistant bracing members maintain elasticity, provide sufficient lateral stiffness for the main structure, and limit structural displacement; under the action of moderate and large earthquakes,...

Problems solved by technology

Generally used reinforced concrete peripheral restraint members, when pouring concrete, the reserved gap between the two is difficult to meet the accuracy requirements

In response to this problem, some scholars have proposed a prefabricated anti-buckling support, the distance between the inner core member and the outer restraint member can be effectively controlled and adjusted, but the production and installation are more complicated
