A Fully Assembled Segmented Buckling-Resistant Brace That Can Directly Replace the Inline Core

Abstract

The inVention relates to a fully-assembled segmented anti-buckling support with I-shaped cores capable of being directly replaced and belongs to the field of structural engineering. The anti-bucklingsupport comprises two edge core components, n intermediate core components, two edge assembled peripheral restraining deVices with flange plates, n-1 intermediate assembled peripheral restraining deVices with flange plates, 2(n+1) core outer connecting coVer plates, a first high-strength bolt group and a second high-strength bolt group. On the basis of a segment assembled design concept of the components, the super-long and super-heaVy anti-buckling support is diVided into seVeral segments to oVercome the defect of inconVenience of the long and heaVy components in the process of machining, transportation and installation. An axial force is transmitted through segmented jacking of the core outer connecting coVer plates and the core components, and weakening parts are arranged on the core components to achieVe plastic damage control. Through the arrangement aboVe, according to the anti-buckling support, there is no need to dismantle the peripheral restraining deVices after an earthquake,the damaged core components can be directly detached from the peripheral restraining deVices for replacement, and post-earthquake repair work is optimized.

Description

technical field [0001] The patent relates to a fully-assembled segmented anti-buckling support that can directly replace the inline core, and belongs to the technical field of structural engineering. Background technique [0002] The anti-buckling support is composed of inner core member and peripheral restraint device. The inner core member bears axial pressure, and the peripheral device constrains the lateral displacement of the inner core member, so that the full section yields under the action of axial pressure. Since the Hanshin Earthquake in Japan and the Northridge Earthquake in the United States in the 1990s, anti-buckling braces have undergone a lot of engineering practice in some developed countries such as the United States and Japan. " and "energy dissipation under large earthquakes", making it one of the best energy-dissipating and shock-absorbing components, and it has been rapidly popularized and applied in recent years. [0003] At present, for the prefabric...

Problems solved by technology

[0008] The present invention proposes a fully-assembled segmented anti-buckling support that can directly replace the inline core, aiming to solve the inconveniences of the existing super-long and super-heavy assembled anti-buckling supports in the process of processing, transportation and installation, and The disadvantages of dismantling the assembled peripheral restraint device when replacing the core components after the earthquake reduce costs, improve efficacy and timeliness, optimize post-earthquake repair work, and provide more options for heavy-duty assembled anti-buckling supports
