Energy dissipation component arranged in axial direction of inhaul cable

Abstract

An energy dissipation component arranged in the axial direction of an inhaul cable comprises an outer barrel, an inner barrel, a spring and a bolt pair. The outer barrel is a hexahedral cavity body, wherein a center hole is formed in one end face of the outer barrel, a second lug ring is arranged on another end face of the outer barrel, and the ends, close to the second lug ring, of the rest four faces of the outer barrel are respectively provided with at least one bolt hole. The inner barrel is placed inside the outer barrel and is formed by a section of round tube and a section of rectangular steel tube with the tube diameter being far larger than the external diameter of the round tube in a connecting mode, the end of the round tube slidably penetrates into the center hole formed in the outer barrel from inside to outside, and a first lug ring is further arranged on the end face of the round tube. Kidney-shaped bolt holes with the long diameter in the axial direction are all formed corresponding to the bolt holes formed in the outer barrel in the four faces of the rectangular steel tube. The round tube of the inner barrel is sleeved with the spring, one end of the spring abuts against the end face where the rectangular steel tube and the round tube of the inner barrel are connected, and the other end of the spring abuts against the inner end face of the end, being provided with the center hole, of the outer barrel. The outer barrel and the inner barrel are connected into a whole through the bolt pair. The energy dissipation component arranged in the axial direction of the inhaul cable is stable and good in energy-dissipating capacity, simple in connecting structure and convenient to construct.

Description

technical field [0001] The invention belongs to the technical field of building structures, and relates to an energy-dissipating element for earthquake resistance and disaster reduction in civil engineering, in particular to an energy-dissipating element arranged axially along a cable. Background technique [0002] With the continuous progress of engineering technology and the development of material technology, the role of prestressed cables in building structures and bridge engineering is increasingly recognized and mastered by engineers and technicians, and the cable materials of prestressed cables are also increasingly diversified. Steel wire cable body, steel strand cable body, steel wire cable body and steel tie rod cable body, structures with prestressed cables are increasingly used in long-span public and industrial buildings and long-span bridge projects, such as stadiums, Terminal buildings, performance venues, convention centers, large commercial centers, long-spa...

AI Technical Summary

Problems solved by technology

For the prestressed cable structure, the internal force of the prestressed cable will fluctuate greatly during the earthquake or wind disaster, and the energy dissipation of the cable itself can only be resisted by the elastic energy of the cable, and it is difficult to effectively dissipate the earthquake transmission to the main body. The energy of the structure does not have the function of distributing disasters
