Assembly type multi-limb L-shaped special-shaped column with recoverable function and assembly method thereof

Abstract

The invention provides an assembly type multi-limb L-shaped special-shaped column with a recoverable function and an assembly method thereof. An L-shaped supporting face comprises three sets of supporting frames and three sets of force-holding steel structures correspondingly arranged on the supporting frames, and the force-holding steel structures are wrapped with force-holding rubber plates; a core column can be matched with the force-holding steel structures to transmit loads to a bracket, in the process, the local areas, located on the upper portion of the bracket, of the force-holding rubber plates can generate elastic compression deformation, and thus a top plate and the force-holding plates generate relative displacement; and a plurality of dampers are arranged between the force-holding plates and the detachable top plate, and the dampers consume a large amount of seismic energy when the core column and the force-holding plates generate relative displacement. The L-shaped special-shaped column arranged in the structure is suitable for the corner of a building, the structural stability is high, thus the L-shaped special-shaped column has the enough anti-torsion capacity, meanwhile, the function of replacing the dampers can further be achieved, and the service life of the structure is prolonged. The L-shaped special-shaped column can be automatically reset under the effect of a small earthquake or a medium earthquake, and after the effect of a large earthquake, the structural function can be rapidly recovered only by adjusting the positions of all the components and replacing the dampers.

Description

technical field [0001] The invention relates to the technical field of structures, in particular to an assembled multi-legged L-shaped special-shaped column and an assembly method thereof with recoverable functions. Background technique [0002] The structural column bears the main vertical force in the earthquake. If it is damaged by a large earthquake at the epicenter, it will need to be repaired and strengthened, and the building will lose its safety capability if it is severe. The structural column at the corner of the existing building has a small section moment of inertia, which makes the torsion resistance of the corner structural column weak. In order to reduce the torsion phenomenon, the method of increasing the cross-sectional area is usually adopted, but this method will obviously affect the use of the building. , so special-shaped columns can also be used to bear the upper load according to the structural layout. Recoverable function is a new form of structural ...

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
