Embodiment

[0032] Such as figure 1 As shown, the thread splicing node of the square steel pipe column includes the upper square steel pipe column 1 and the lower square steel pipe column 2 to be spliced. Such as figure 2 and image 3 As shown, first in the factory, the upper square steel pipe column 1 and the upper round steel pipe splicing section 3 provided with internal threads are welded and connected at the tangent position with a fillet weld 9, and the height of the weld seam is not less than the wall thickness of the square steel pipe. The connecting plate 5 is used to weld the upper square steel pipe column 1 and the upper round steel pipe splicing section 3 provided with internal thread through the welding joint 10 of the connecting plate. The lower square steel pipe column 2 and the lower circular steel pipe splicing section 4 with internal thread are welded at the tangent position with fillet weld 9, and then the connecting plate 5 is used to connect the lower square steel ...

Abstract

The invention relates to a threaded-connection square steel pipe column and a construction method. The threaded-connection square steel pipe column comprises a plurality of square steel pipe column units, the square steel pipe column units are in threaded connection by arranging round steel pipes with threads at the splicing sections, and the square steel pipe column units and the round steel pipes with the threads are connected through weld seams and multiple layers of splicing plates. Each square steel pipe column unit located on the upper section is provided with crowbar holes, when every two square steel pipe column units adjacent vertically are hung in place, force is exerted on a crowbar inserted into the crowbar holes to screw down the square steel pipe column unit located on the upper section, and threaded connection between the square steel pipe column units is completed. The defects that on-site joint welding is low in efficiency and quality and are affected by weather and climate are overcome. The requirement for the technological level of installers is lowered, and round steel pipe columns can be spliced through simple operation.

Description

technical field [0001] The invention relates to a threaded square steel pipe column and a construction method, belonging to the field of construction engineering. Background technique [0002] At present, the splicing of square steel pipe columns in construction projects mainly adopts on-site welding. This splicing method has strict quality requirements for the factory production of steel columns and the on-site splicing of nodes. During factory production, inner partitions need to be set in the upper steel pipe column and the lower steel pipe column to avoid extrusion deformation of steel pipes in transportation engineering and welding deformation during on-site welding. In order to ensure the quality of on-site welding, the upper steel pipe column and the lower steel pipe column need to be beveled, and a welding backing plate should be provided. During on-site splicing, it is necessary to set temporary connection lugs on the outer sides of the upper steel pipe column and...
