Problems solved by technology

[0003] The purpose of the present invention is to provide a concrete-filled steel tube column and its construction method. It is necessary to solve the problem of waste of materials in giant concrete-filled steel tube columns in the existing assembled steel-concrete composite structure system of super high-rise and large-span complex structures. Large workload, low degree of assembly, slow construction period, high project cost and technical problems that are difficult to guarantee the construction quality

Embodiment 1

[0056] Embodiment one sees Figure 1-5 As shown, a concrete-filled steel pipe column includes a steel pipe column and core concrete 1 poured inside the steel pipe column. 2. The capital section 3 on the topmost floor.

[0057] The top node area of ​​the column bottom section 2 is provided with a top connection structure, and the top connection structure includes a top stiffening diaphragm 4 provided on the inner wall of the steel pipe column, and the elevation of the top stiffening diaphragm 4 is lower than that of the steel pipe where it is located. The elevation of the top surface of the column, the steel pipe column on the upper side of the top stiffened diaphragm 4 and the top stiffened diaphragm form the top slot.

[0058] The bottom node area of ​​the column top section 3 is provided with a bottom connection structure, and the bottom connection structure includes a bottom stiffening diaphragm 5 provided on the inner wall of the steel pipe column, and the elevation of th...

Embodiment 2

[0081] Embodiment two see Figure 1-7 As shown, in order to increase the column height in this embodiment, the difference compared with the first embodiment is that in addition to the column top section and column bottom section, a standard column section is added in the middle. The steel pipe column section also includes a standard column section 15 arranged between the column bottom section 2 and the column top section 3, the top node area of ​​the standard column section 15 is provided with a top connection structure, and the bottom of the standard column section 15 The node area is provided with a bottom connection structure, the top connection structure and the steel pipe column section on the upper side are also inserted through the bolt column 6 in the node area, and the bottom connection structure and the steel pipe column section on the lower side are also inserted through the bolt column 6 in the node area.

[0082] The difference between the construction method of t...

Abstract

The invention relates to a concrete-filled steel tube column and a construction method thereof. The concrete-filled steel tube column comprises a steel tube column and a core concrete, layers of steeltube column sections are assembled to form the steel tube column, the steel tube column sections include a bottom column section and a top column section, the top node area of the bottom column section is provided with a top connecting structure, the bottom node area of the top column section is provided with a bottom connecting structure, the concrete-filled steel tube column further comprises anode area pin column, a convex limit ring of the node area pin column divides the node area pin column into an upper plug and a lower plug, the height of the lower plug is matched with the height ofa top slot and the lower plug is inserted into the top slot, the upper plug is inserted into a bottom slot, and the concrete-filled steel tube column further comprises a concrete prestressing tendon which vertically runs through the column body. The invention is applicable to super high-rise complex structure type buildings, large-span complex structure type buildings and the like, the applicationrange is wide, the invention can ensure that the overall rigidity, strength and stability of a building structure can meet design requirements, and the potential safety hazards and later maintenanceand repair costs of the building structure can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of assembled steel-concrete composite building structures, in particular to an assembled bolt prestressed steel pipe concrete column and a construction method thereof. Background technique [0002] In the existing prefabricated steel-concrete composite structure system, the application technology of steel tube concrete columns is very mature, and the application of prestressing technology in municipal bridge engineering is also very mature. However, the application of prestressed steel pipe concrete columns is very little. In buildings with complex structures such as super high-rise buildings and long-span buildings, giant columns appear due to design standards and specifications, which are neither economical nor beautiful, and seriously affect the use. Require. In addition, steel structure buildings are originally prefabricated buildings, but there are still a large number of on-site welding operations in the curren...
