Buckling-restrained corrugated pipe energy dissipation supporting device based on ring spring self-resetting and manufacturing method

Abstract

The invention relates to a buckling-restrained corrugated pipe energy dissipation supporting device based on ring spring self-resetting and a manufacturing method. The buckling-restrained corrugated pipe energy dissipation supporting device comprises an outer sleeve, a high-strength steel ring spring set, a middle sleeve, a corrugated pipe and an inner sleeve which are sequentially and coaxially arranged from outside to inside in a sleeving mode. A pair of outer annular baffles are fixedly connected to the inner wall of the outer sleeve, the outer wall of the middle sleeve is fixedly connected with a pair of inner annular baffles, the high-strength steel ring spring set is arranged between the pair of outer annular baffles, one end of the outer sleeve is closed, the other end of the outer sleeve forms a through hole for the middle sleeve to penetrate through a first end plate extending inwards from the end of the outer sleeve, the middle sleeve penetrates through the through hole of the outer sleeve and is in sliding connection with the first end plate, one end of the middle sleeve is closed, and the other end of the middle sleeve is open, the open end is in sliding connection with the inner wall of the outer sleeve through a second end plate extending outwards from the end part of the middle sleeve; one end of the corrugated pipe is fixedly connected to the closed end of the middle sleeve, the other end of the corrugated pipe is fixed to the closed end of the outer sleeve, one end of the inner sleeve is fixed to the closed end of the outer sleeve, and stable and efficient energy dissipation capacity and a self-resetting function are achieved.

Description

technical field [0001] The invention relates to an energy dissipating support device and a manufacturing method thereof, in particular to a buckling restraint bellows energy dissipating support device based on the self-resetting of ring springs and a manufacturing method thereof, belonging to the technology of shock absorption (vibration) and vibration isolation (vibration). field. [0002] technical background [0003] With the development of structural passive damping control technology, many types of damping and energy-consuming devices have been developed. The anti-buckling brace is one of the widely used shock absorption devices at present, and its advantages are simple design parameters and low cost. However, the residual displacement of traditional anti-buckling bracing after earthquake is relatively large, which increases the difficulty of structural repair and increases the direct or indirect economic loss. Therefore, the research on anti-buckling bracing with self-...

Problems solved by technology

However, the residual displacement of the traditional anti-buckling brace after the earthquake is relatively large, which increases the difficulty of structural repair and increases the direct or indirect economic loss. Therefore, the research on the anti-buckling brace with self-resetting function is of great significance

[0004] At present, there are many structural forms of self-resetting anti-buckling braces, and there are the following problems: the deformation capacity of self-resetting anti-buckling braces using prestressed tendons is insufficient under strong earthquakes; the price of shape memory alloy materials is high, and temperature sensitivity and performance need to be solved Stability and other issues; the stroke provided by the butterfly spring is short, and has no energy dissipation capacity, and requires a lot of welding or assembly work; the existing self-resetting anti-buckling support structure is complicated, the installation process is cumbersome, and due to the performance, the energy consumption performance of the support becomes weaker
