A lap joint self-centering friction energy dissipation support

Abstract

The invention discloses a lap joint type self-centering frictional energy dissipation support, which comprises a rectangular inner sleeve, a rectangular outer sleeve, a frictional energy dissipation part connecting the bottom plate of the inner sleeve and the bottom plate of the outer sleeve, and a first The end plate, the second end plate arranged in the outer casing, the pre-tension rod arranged in the inner casing and anchored to the first end plate and the second end plate at both ends respectively, a part of the inner casing is inserted into the outer casing and connected with it Overlapping, the end of the inner sleeve inserted into the outer sleeve is in contact with the second end plate, the first end plate is in contact with one end of the outer sleeve, the top plate and the bottom plate of the non-lapped end of the inner sleeve are respectively connected with the first connecting plate, and the outer sleeve The top plate and the bottom plate of the non-overlapping end of the pipe are respectively connected with a second connecting plate; the first end plate is in contact with the push plate of the inner casing through the set first end plate rubber pad, and the second end plate is set through the set second end plate rubber pad. The pad is in contact with the inner casing push plate.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a lap joint type self-centering friction energy consumption support for reducing earthquake disasters of engineering structures. Background technique [0002] Earthquakes bring extremely serious disasters to human beings. The traditional seismic design adopts the ductility design method, that is, under the action of an earthquake, through the early yield and failure of some structural components, but the overall function will not be lost, relying on the plastic deformation of the components to dissipate most of the seismic energy, so as to achieve The purpose of ensuring the safety of the main structure. [0003] Frictional energy-dissipating support is an energy-dissipating member that converts kinetic energy into heat energy through sliding friction to dissipate seismic energy. Due to its strong energy dissipation capacity, good shock absorption effect, and easy replacement aft...
