Steel frame columns with articulating devices

Abstract

The invention discloses a steel frame column with a joint type connection device, comprising a steel frame column body 5, a cross-shaped stiffening plate 10 fixedly connected to the inner surface of the top of the steel frame column body, and the steel frame column body The top is fixedly connected with the upper partition 8, the upper surface of the upper partition is connected with the reinforcing steel bar 11, the edge of the upper partition is connected with the lower end of the upper short column 6, and the bottom end of the steel frame column body is fixedly connected with the lower partition 9, The middle part of the lower partition is provided with a hole 13, and an exhaust overflow hole 14 is arranged around the hole. The edge of the lower partition is fixedly connected with the top of the lower short column 7, and the inner surface of the upper and lower short column side walls Riveting bolts are provided; concrete pouring holes 15 and grout holes 16 are provided on the side walls of the steel frame columns. The present invention solves the problem that two adjacent steel frame columns cannot be welded due to the small distance. At the same time, due to the arrangement of reinforcing bars and concrete in the steel frame column, the lateral bending resistance of the connection between the upper and lower steel frame columns is greatly improved.

Description

technical field [0001] The invention belongs to the field of construction engineering steel structures, and relates to a steel frame column with an articulating connection device. Background technique [0002] With the vigorous promotion and implementation of the national housing industrialization strategy, modular steel structure buildings have quietly emerged in the construction field with the advantages of greenness, environmental protection, energy saving, consumption reduction, building recycling, reduction of engineering waste, and conservation of land resources. The main body of the building is prefabricated into modules of various specifications in the factory, and after being transported to the site, it is hoisted and installed by lifting equipment to form a high-rise building. When each unit module is installed, the horizontal and vertical connections between modules are welded. Since the modules are tightly spliced, the vertical welding of the steel frame column ...

AI Technical Summary

Problems solved by technology

Due to the tight splicing between the modules, the vertical welding of the steel frame column as the main stress member of the building in each unit module has the problem of welding difficulties

like figure 1 as shown, figure 1 There are four steel frame columns as shown, steel frame column 1 is adjacent to steel frame column 2, steel frame column 3 is adjacent to steel frame column 4, and the gap between two adjacent columns is small, when steel frame column 1 and steel frame column After the steel frame column 3 has completed the welding of the upper and lower joints along the four sides of the outer surface of the steel frame column, when welding the upper and lower joints of the steel frame column 2 and steel frame column 4, due to the two steel frame If the gap between adjacent columns is small, only the three sides of the steel frame column surface where the steel frame column 2 and the steel frame column 4 meet can be welded, while the inner side 17 cannot be welded, thus reducing the The ability of steel frame columns to resist lateral bending, the existence of this defect has seriously affected the widespread promotion of modular steel structure buildings
