Twisted combined steel pipe column and manufacturing method thereof

Abstract

The invention discloses a twisted combined steel pipe column. The twisted combined steel pipe column comprises wall plates, a support jig frame, a baseplate, an inner separation plate, a positioning sealing plate and brackets, wherein assembly control wires are arranged on the wall plates; the support jig frame is fixed in an appointed construction site; the baseplate is arranged above the support jig frame; the wall plates are arranged at the two sides of the baseplate; the inner separation plate is arranged between the two wall plates; the positioning sealing plate is arranged at the tops of the two wall plates to form a cylinder; and the brackets are arranged at the upper side and two sides of the cylinder. The twisted combined steel pipe column forms the wall plates through twisting blanked parts, the assembly control wires for twisting a box mold are arranged on the wall plates, and detection reference lines are arranged on the molded wall plates, so that the machining precision is improved; the inner separation plate is elliptical, and is arranged between two twisted parts; and the size thereof is matched with a gap between the two twisted parts, so that the support capacity of the cylinder in the twisted steel pipe column is further improved, and the construction requirements are preferably satisfied.

Description

technical field [0001] The invention relates to a production device, in particular to a twisted combined steel pipe column and a processing and manufacturing method thereof. Background technique [0002] With the rapid development of social economy, the rhythm of people's life and work is constantly developing. At present, most buildings are constructed of reinforced concrete. However, due to the large labor required for construction, the construction period of the entire building It is too long, and at the same time, the requirements for the weather are relatively high. Normal construction cannot be carried out in rainy days or winter, which leads to a longer construction period of the entire project and affects the normal delivery of the developer. Therefore, many developers now choose to use steel structures. The building replaces the existing reinforced concrete building. [0003] However, due to the less use of steel structure buildings, its technology is not yet matur...

Problems solved by technology

[0002] With the rapid development of social economy, the pace of people's life and work is constantly developing. At present, most buildings are constructed of reinforced concrete. However, due to the large labor required for construction, the construction period of the entire building It is too long, and at the same time, the requirements for the weather are relatively high. Normal construction cannot be carried out in rainy days or winter, which leads to a longer construction period of the entire project and affects the normal delivery of the developer. Therefore, many developers now choose to use steel structures. The building replaces the existing reinforced concrete building

[0003] However, due to the less use of steel structure buildings, its technology is not yet mature enough, so there are still more or less deficiencies in the design and use of structures, such as twisted composite steel pipe columns, most of the existing technologies are wall-to-wall The slab is simply twisted and then put into use. Its stability is poor during use, which leads to safety hazards in the entire component. Therefore, the existing twisted composite steel pipe columns cannot meet the needs of construction.
