Double-cylinder type multi-limb square column capable of recovering functions and assembling method thereof

Abstract

The invention provides a double-cylinder type multi-limb square column capable of recovering functions and a manufacturing method. An outer cylinder frame arranged outside an inner cylinder frame in a sleeving mode forms a double-cylinder type multi-limb supporting structure, and the stability and adaptability of the double-cylinder type multi-limb square column capable of recovering the functions are improved for the complex situation in an earthquake; a steel corbel on the inner cylinder frame disperses force in the vertical direction to a force holding main beam of the outer cylinder frame, and the force borne by each assembly independently is reduced; a replaceable component can consume the force borne in the non-vertical direction, the stability of the double-cylinder type multi-limb square column capable of recovering the functions is further guaranteed, meanwhile, after the replaceable component is damaged, the replaceable component can be replaced, and the service life of the double-cylinder type multi-limb square column capable of recovering the functions is prolonged. According to the double-cylinder type multi-limb square column capable of recovering the functions and the manufacturing method, the structure is compact, the occupied space is small, complex damage caused by high-strength earthquakes can be avoided, and the problems that in the prior art, building structure columns are poor in supporting stability, complex in structure and low in strength are solved.

Description

technical field [0001] The invention relates to the technical field of structures, in particular to a double-tube multi-leg square column with recoverable functions and an assembly method thereof. Background technique [0002] The column is a kind of vertical load-bearing member. The traditional column bears the bending, shearing and torsion action during the earthquake, which may easily lead to structural damage of the column and thus lose its structural function. Once the structural safety of the pillars is damaged, the entire building must be evacuated. If it is light, it needs to be inspected and reinforced, and if it is heavy, it needs to be demolished and rebuilt outside the building. This process will cause great hidden dangers to the safety of people's lives and property. [0003] Recoverable function is a new form of structural function. A structure with a recoverable function can be quickly restored after a small earthquake and replaced in time after a major earth...

This process will cause great hidden dangers to the safety of people's lives and property.

[0003] Recoverable function is a new form of structural function. A structure with a recoverable function can be quickly restored after a small earthquake and replaced in time after a major earthquake. However, it is difficult for a column to achieve a recoverable function. Complicated forces, difficult to replace columns and complicated engineering construction techniques, etc.
