Multi-cavity concrete column and construction method thereof

Abstract

The invention relates to the technical field of building structures, in particular to a multi-cavity concrete column. The concrete column comprises a supporting piece, at least one external connecting plate and at least one flange plate, wherein, the supporting piece comprises at least one plate body, one flange plate is fixedly arranged at the side end of each plate body, and every two adjacent flange plates are fixedly connected through one external connecting plate; a cavity column with at least two cavities is defined by the supporting piece, the flange plates and the external connecting plates, each cavity is filled with concrete, and at least one outer cavity wall of the cavity column is provided with a groove used for being fixedly embedded into a filler wall. The multi-cavity concrete column is simple in structure, good in stress performance and convenient in installation and construction; and the effect of relieving the cold and hot bridge effect can be achieved after the grooves and the filler wall are embedded and fixed. The invention further provides a construction method of the multi-cavity concrete column.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a multi-cavity concrete column and a construction method thereof. Background technique [0002] With the progress of society, the building structure develops towards the direction of towering and large span. In order to meet the mechanical performance of the traditional single-steel concrete column, the cross-section of the steel pipe needs to be set very large or very thick, which leads to high cost, heavy weight and long construction period. [0003] At the same time, in order to enhance the bonding performance between the steel pipe and concrete or strengthen the connection between the internal section steel and the external steel pipe, the traditional steel pipe concrete column usually chooses to install stiffeners, inner partitions or studs inside the steel pipe, which is not easy to construct. In addition, when the traditional CFST column is connected to the fi...

In order to meet the mechanical performance of the traditional single steel pipe concrete column, the cross section of the steel pipe needs to be set very large or very thick, which leads to high cost, heavy weight and long construction period

[0003] At the same time, in order to enhance the bonding performance between the steel pipe and concrete or strengthen the connection between the internal section steel and the external steel pipe, the traditional steel pipe concrete column usually chooses to install stiffeners, inner partitions or studs inside the steel pipe, which is not easy to construct.

In addition, when the traditional CFST column is connected to the filled wall, steel bars are usually used to tie it, or to weld the slot connection at the joint position of the CFST column, which is troublesome in construction and requires many construction procedures; One side is located indoors, and one side is located outdoors. Due to the good thermal conductivity of steel, a cold and heat bridge effect may be formed at the connection position, which may easily cause the wall decoration materials to be damp and accelerate corrosion.
