Problems solved by technology

However, in this scheme, there are many side columns with variable cross-sections, and there are arc-shaped areas, and the concrete material is relatively brittle. Therefore, the construction of the side columns in this technical scheme is difficult, and the core column and side columns will be damaged during the earthquake. It is easy to squeeze each other and cause some areas to be crushed, resulting in component failure

Embodiment Construction

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0048] refer to Figure 1-13 , an assembled multi-leg square column with recoverable functions, including a force-bearing steel structure 3, a damper and a plurality of rectangularly arranged limb columns 1, two adjacent limb columns 1 are rigidly connected, and a force-bearing steel structure 3 Located between multiple limb columns 1 , the damper is located at the lower part of the support plate 6 and connected with the connection plate 9 at the bottom of the core column 10 .

[0049] The force-holding steel structure 3 includes a square steel pipe 31, the outside of which is coated with a force-holding rubber 4, and the side walls of the square steel pipe 31 are evenly distributed with a plurality of horizontal steel corbels 33, a plurality of steel corbels 33 Embedded in the force-be...

Abstract

The invention provides an assembly type multi-limb square column with a recoverable function and an assembly method thereof. The assembly type multi-limb square column comprises a force-holding steel structure, a damper and a plurality of limb columns arranged in a rectangular shape, wherein every two adjacent limb columns are rigidly connected, the force-holding steel structure is located among the limb columns, a steel corbel of the force-holding steel structure is located at the upper end of a corbel, force-holding rubber transmits a load to the corbel through the steel corbel, meanwhile the force-holding rubber has certain elasticity, the force-holding rubber can be pressed and deformed near the area of the corbel, and the force-holding rubber can make a core column have a large displacement trend. The multi-limb square column can be self-reset in a small earthquake or a medium earthquake, and the structural function of the multi-limb square column can be quickly recovered only by replacing the damper and readjusting the positions of all parts after a large earthquake.

Description

technical field [0001] The invention relates to the technical field of structures, in particular to an assembled multi-leg square column with recoverable functions and an assembly method thereof. Background technique [0002] Structural column is an important component of bearing building structure. Structural column bears the main vertical force in an earthquake. If it is damaged by a large earthquake at the epicenter, it will require maintenance and reinforcement, and the building will lose its safety. Restorable function is a new form of structural function. A structure with restorable function can be easily repaired after a small earthquake and replaced in time after a major earthquake to quickly restore its structural function. [0003] In the existing technical scheme, a multi-limb square column with a built-in core column with recoverable function is announced. This technical scheme installs the core column, attaches the side column to the core column, and then instal...
