Embodiment

[0031] Including the upper round steel column 1 and the lower round steel column 2 to be spliced, the upper splicing section 3 with internal threads, the lower splicing section 4 with external threads, high-strength bolts 5 to prevent the threads from loosening, and crowbars for temporary installation 6 and the crowbar hole high-strength bolt 7 that fills up the crowbar hole. In the factory, the upper circular steel pipe column 1 to be spliced ​​is welded to the upper splicing section 3 provided with internal threads, and the lower circular steel pipe column 2 to be spliced ​​is welded to the lower splicing section 4 provided with external threads. At the construction site, first hoist the upper round steel pipe column 1 into place, then insert the crowbar 6 into the preset hole of the upper round steel pipe column 1 and penetrate the column body, wherein the preset holes are arranged in pairs along the diameter of the pipe body, so that The crowbar 6 can pass through the pipe...

Abstract

The invention relates to a circular steel tube column in threaded connection and a construction method. The circular steel tube column in threaded connection comprises a plurality of circular steel tube column units, the circular steel tube column units are in threaded connection at splicing segments, and the circular steel tube column units are linked to the splicing segments by use of welding. A circular steel tube column unit at an upper segment is provided with crowbar holes enabling crowbars to pass through; and when two circular steel tube column units adjacent to each other at an upper position and a lower position are hoisted in place, and the upper-segment circular steel tube column unit is screwed tight through applying forces to the crowbars inserted into the crowbar holes so as to finish threaded connection between the circular steel tube column units. The threaded connection pitch point provided by the invention overcomes the disadvantages of low efficiency of onsite welding pitch points, low quality, influences exerted by weather and climate and the like. The requirements for technical level of installation workers are reduced, and the circular steel tube columns can be spliced through simple operation.

Description

technical field [0001] The invention relates to a threaded round steel pipe column and a construction method, belonging to the field of construction engineering. Background technique [0002] At present, the splicing of circular 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. When the factory manufactures, it is necessary to set inner partitions in the upper and lower round steel pipe columns to avoid the extrusion deformation of the steel pipes in the transportation project and the welding deformation during the on-site welding process. In order to ensure the welding quality on site, the upper round steel pipe column and the lower round steel pipe column need to be beveled and the welding backing plate should be set. During on-site splicing, it is necessary to set temporary connection lugs on the outer sides of the ...
