Fully assembled segmented anti-buckling supporting member with crossed cores capable of being directly replaced

Abstract

The invention relates to a fully assembled segmented anti-buckling supporting member with crossed cores capable of being directly replaced, and belongs to the field of structural engineering. The anti-buckling supporting member is composed of two edge section crossed core components, n middle section crossed core components, two edge section assembled-type peripheral constraining devices, (n-1) middle section assembled-type peripheral constraining devices, 4(n+1) core outer side L-shaped connecting members, a first high-strength bolt group and a second high-strength bolt group. Based on a component segmented assembled-type designing concept, an ultra-long ultra-heavy anti-buckling supporting member is divided into a plurality of sections to overcome the inconveniences of long and heavy components during the processing, transporting and installing processes. The core outer side L-shaped connecting members and the core components are arranged to tightly jack and transmit axial force in segments, weakening areas are arranged on the core components to achieve plasticity damage control, the releasing and replacing of damaged cores can be achieved without dismantling the peripheral constraining devices from the anti-buckling supporting members by the above arrangements, and post-quake repairing operation is optimized.

Description

technical field [0001] The patent relates to a fully-assembled segmented anti-buckling support that can directly replace a cross-shaped inner 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...

AI Technical Summary

Problems solved by technology

[0008] The present invention proposes a fully-assembled segmented anti-buckling support that can directly replace the cross-shaped core, aiming to solve the inconveniences of the existing ultra-long and super-heavy assembled anti-buckling supports in the process of processing, transportation, and installation, as well as the After the earthquake, the disadvantages of dismantling the assembled peripheral restraint device are required when the inner core component is replaced, which reduces the cost, improves the efficacy and timeliness, optimizes the repair work, and also provides more choices for the heavy-duty assembled anti-buckling support form
