Flexible connected joint structure of externally-bonded masonry wall and steel column

Abstract

The invention relates to a flexible connected joint structure of an externally-bonded masonry wall and a steel column. The masonry enclosure wall is bricked by being attached to a steel-structure-factory-building enclosure wall, and the masonry enclosure wall and the column are pulled and tied, and measures are taken to enable a wall body to not hinder the longitudinal horizontal displacement of a structure factory building column. The flexible connected joint structure comprises the steel column and the externally-bonded masonry wall. Grooves are reserved in the externally-bonded masonry wall in an interrupted mode and the externally-bonded masonry wall is provided with sliding connection devices, the sliding connection devices are fixed to the steel column through mechanical buckles, concrete is poured in the grooves reserved in the externally-bonded masonry wall in an interrupted mode to form reinforced concrete short beams, and the sliding connection devices are wrapped in the grooves. According to the flexible connected joint structure of the externally-bonded masonry wall and the steel column, through arrangement of the special connection devices between the externally-bonded masonry wall and the steel column, connection of the externally-bonded masonry wall and the steel column is achieved, and the mechanical performance of a major structure is greatly improved; and on the premise that effective pulling and tying of the wall body and the steel column are ensured, longitudinal free deformation of the wall body and the steel column can be met, and further the safety of the major structure is effectively protected under the influence of an earthquake.

Description

technical field [0001] The invention belongs to the technical field of steel structure engineering, and in particular relates to a flexible connection node structure of an externally attached masonry wall and a steel column. Background technique [0002] According to the "Code for Seismic Design of Buildings" (GB5011), the requirements for seismic construction measures of non-structural components, for the enclosure walls of steel structure workshops, the masonry enclosure walls should be pasted and tied to the columns, and measures should be taken so that the walls do not hinder The horizontal displacement of the vertical column of the structural factory building. At present, the method often used in the engineering field is to set up structural columns at the junction of the enclosure wall and the steel column, and effectively connect the enclosure wall and the steel column by welding tie bars. This method can meet the requirements of the standard wall and steel column ti...

Problems solved by technology

This method can meet the requirements of the standard wall and steel column tie, and ensure the rigidity of the wall outside the surface. The longitudinal free deformation hinders the longitudinal horizontal displacement of the structural plant column, which is contrary to the requirement of the code that "the wall does not hinder the longitudinal horizontal displacement of the structural plant column".
