An assembled anti-buckling support

Abstract

The invention discloses an assembled anti-buckling support, which comprises: a support inner core plate assembly; a detachable external restraint assembly, the detachable external restraint assembly is arranged around the outer periphery of the middle part of the support inner core plate assembly; a detachable end There are two detachable end restraint assemblies, and the two detachable end restraint assemblies are respectively arranged on the outer peripheral sides of the top and bottom of the supporting inner core plate assembly, and are respectively connected with the detachable external restraint assemblies The top and bottom ends are detachably connected. The anti-buckling support adopts detachable external restraint components and detachable end restraint components as the outsourcing restraint units supporting the inner core plate components, without concrete pouring and curing, which can reduce the production cycle and speed up the production progress, and its self-weight is relatively Small, convenient for construction and installation.

Description

technical field [0001] The invention relates to the technical field of energy-dissipating supports for building structures, in particular to an assembled anti-buckling support. Background technique [0002] Earthquakes can lead to serious damage or even collapse of building structures, resulting in massive property losses and casualties. However, the use of energy-dissipating shock-absorbing devices and technologies can effectively absorb external vibration energy and greatly reduce the degree of damage to buildings and structures. [0003] Buckling-resistant brace is a common energy-dissipating and shock-absorbing element that uses the plastic deformation of the inner core to dissipate seismic energy, and is widely used in civil engineering structures. Under small earthquakes, anti-buckling braces can provide lateral stiffness to the main structure. Under large earthquakes, anti-buckling braces can yield under tension or compression, and exhibit good hysteretic energy dissi...

Problems solved by technology

[0005] However, the traditional buckling-resistant bracing using concrete-filled steel tubes as constraining units has the following disadvantages: ①The production cycle is long, that is, after the traditional buckling-resistant bracing with concrete-filled steel tubes is finished with mortar or concrete pouring, it takes at least 7 days to repair the concrete. After curing, it can be transported to the site for subsequent installation after its concrete strength increases; ②The quality of the product is not easy to guarantee and its weight is large, which makes it difficult to construct and install, that is, the traditional buckling-resistant brace of steel pipe concrete is easy to attach to the core unit when pouring concrete The unbonded material on the outside causes damage, and the gap between the constrained unit and the core unit is also difficult to control, and the self-weight of this support is too large, which is not convenient for construction and installation; ③The service life is insufficient, that is, the buckling-resistant support made of ordinary low-carbon steel The anti-rust coating on the outer surface of the product is easily damaged during processing, transportation, installation and use and loses its anti-rust effect, resulting in serious corrosion far before reaching the service life, reducing the service life
