Connection nodes and connection methods of cold-formed steel house beams and square steel tube concrete columns

Abstract

The invention discloses a connection node between a cold-formed steel building beam and a square steel pipe concrete column. The connection node includes a column connection plate, a first beam connection plate, a second beam connection plate, a first stiffening rib, a second stiffening rib, The first inclined plate, the second inclined plate and the reinforcing block, the first beam connecting plate and the second beam connecting plate are parallel to each other and arranged on the same side of the column connecting plate up and down, and the first inclined plate is fixedly connected to the column connecting plate and the first Between the beam connection plates, the first stiffener is fixedly connected between the column connection plate and the first beam connection plate, the second inclined plate is fixedly connected between the column connection plate and the second beam connection plate, and the second stiffener is fixedly connected Between the column connecting plate and the second beam connecting plate, the reinforcing block is fixedly connected between the first beam connecting plate and the second beam connecting plate. The connection node is convenient for the installation of the exterior wall panel, and can be integrated with the steel house beam and the square steel pipe concrete column, which strengthens the integrity of the structure. At the same time, a connection method is also provided, which is easy to construct.

Description

technical field [0001] The invention relates to a building structure, in particular to a connection node and a connection method of a cold-formed steel building beam and a square steel tube concrete column. Background technique [0002] The upper and lower walls of the existing cold-formed steel house structure system are discontinuous. In order to make the structure achieve the purpose of overall anti-side work, it is often to add uplift anchor bolts and shear bolts between the upper and lower discontinuous walls. However, in a multi-layer structure, the cumulative amount of the overall rotational deformation of each layer of the wall caused by the deformation of the anchor bolts will not be negligible, and will significantly reduce the lateral stiffness and bearing capacity of the structure. Chinese patent CN200910029950.6 proposes a multi-storey cold-formed steel composite housing structure. The two ends of each section of the wall are made of square steel pipe concrete ...

Problems solved by technology

However, in a multi-layer structure, the cumulative amount of the overall rotational deformation of each layer of the wall caused by the deformation of the anchor bolts will not be negligible, and will significantly reduce the lateral stiffness and bearing capacity of the structure.

Chinese patent CN200910029950.6 proposes a residential structure of multi-layer cold-formed steel composite houses. The two ends of each section of the wall are made of square steel tube concrete columns, which are arranged vertically and continuously, which strengthens the vertical continuity of the wall. The beam and the square concrete-filled steel tube column are connected by a reinforcing ring, which improves the integrity of the structure, but the existence of the reinforcing ring end plate is not conducive to the installation of the outer wall panel of the outer wall, and will affect the facade effect of the overall structure. Therefore, There is an urgent need for a connection node that is easy to manufacture, easy to construct, and has good structural integrity. It is convenient for the popularization and application of the multi-storey cold-formed steel building structure system.
