A damping steel connector

Abstract

A damping steel bar connector, at least comprising: an outer barrel (1), damping materials (3) and inner barrels (4). The outer barrel (1) is a cylindrical hollow barrel, a partition is provided inside the barrel so as to uniformly partition the barrel into two small barrels which are not communicated with each other, and both ends of the outer barrel (1) are opened. The inner barrels (4) are two cylindrical hollow barrels, one end of each inner barrel is closed, and the other end is opened. The damping materials (3) are disposed between the inner barrels (4) and the outer barrel (1). The damping steel bar connector can be configured to connect assembly type building members having vibration control demands, and when the members are relatively displaced under the action of a power load, damping materials (3) in the damping steel bar connector can produce shear deformation so as to dissipate energy.

Description

[0001] The invention relates to the field of assembled structures and structural vibration control in civil engineering, in particular to a steel bar connector with damping characteristics. [0002] Background technique: [0003] Steel connectors, including sleeve connectors and mechanical connectors, have been widely used in the connection of steel bars between prefabricated components. They have the advantages of stable axial load transmission, convenient construction, and green construction; Vibration is a relatively mature vibration control method at present. The dampers designed and installed based on the theory of damping and vibration reduction are widely used in various buildings all over the world. The damping materials used in the dampers are various, including metal Damping materials, polymers and their composites, and viscous fluids. [0004] A damped rebar connector can be formed by combining a rebar connector with a damping material. Compared with traditional ste...

AI Technical Summary

Problems solved by technology

[0005] At present, traditional steel connectors have reliable mechanical properties in the case of only transmitting axial loads, while the research on the mechanical properties of some steel connectors, such as grouting sleeves, under complex dynamic loads is still in its infancy ; The dynamic interaction mechanism between the steel connectors in some components and the surrounding materials is not yet clear; there are few domestic cases of prefabricated structures that use traditional steel connectors for steel connection due to earthquake loads, so the use of traditional steel The seismic performance of the assembled structure of the connector is still controversial

[0006] It can be seen that the existing prefabricated component connection technology is not perfect, and it cannot make the prefabricated structure have good seismic performance, which restricts the promotion and wide application of the prefabricated structure.
