A self-resetting energy-dissipating support of a piston-type filling compression spring

Abstract

The invention belongs to energy dissipation support components and discloses a piston type compressed spring filled self-reset energy dissipation support which is mainly formed by left and right connecting rods, left and right baffles, an outer sleeve, a piston head, friction plates, cushion plates, high-strength bolts and metal coil springs. Upper and lower surfaces of the piston head are provided with grooves filled with the friction plates, the high-strength bolts penetrate the outer sleeve, the piston head and the upper and lower friction plates sequentially, and a strip groove is formed at a position where the bolts penetrate the outer sleeve. One group of the metal coil springs is arranged between the left baffle and the piston head, and the other group of the metal coil springs is arranged between the right baffle and the piston head. The left connecting rod is connected with the left baffle, the right connecting rod is connected with the piston head, and the middle of the right baffle is perforated to allow the right connecting rod to extend outside the outer sleeve. The piston type compressed spring filled self-reset energy dissipation support realizes excellent energy dissipation capacity and self-reset function through a friction portion and a self-reset portion and applicable to lateral force resistance components in the field of structural and bridge engineering construction.

Description

technical field [0001] The invention belongs to an energy-dissipating support member, relates to the field of disaster reduction and prevention in civil engineering, and in particular relates to a new type of energy-dissipating support member-a piston-type filling compression spring self-resetting energy-dissipating support, which has good energy-dissipating capacity and self-resetting function . Background technique [0002] In January 2009, at the NEES / E-defense U.S. Earthquake Engineering Phase II Collaborative Research Program meeting, American and Japanese scholars first proposed "repairable functional cities" as the general direction of earthquake engineering cooperation. In 2011, Chinese scholars clarified a new concept of structural seismic design - recoverable functional structure. Recoverable function earthquake-resistant structure refers to the structure that can restore its function after an earthquake (fortification or rare earthquake) without repair or a littl...

Problems solved by technology

[0004] The purpose of the invention is to solve the problem of excessive residual deformation of traditional supports under the action of large or moderate earthquakes, which increases the cost of post-earthquake maintenance and reconstruction, as well as the complex structure and cumbersome production and processing of a large number of self-resetting energy-consuming supports at present. A self-resetting energy-dissipating support with a piston-type filling compression spring is proposed, which has a simple structure and is convenient to manufacture.
