Embodiment 1

[0060] like Figure 1-11 As shown, a prefabricated function recoverable steel frame concrete composite column is located on the foundation 8, including 1 set of steel pipe main columns 1, 4 sets of steel pipe subordinate columns 2, 16 main and slave columns energy-dissipating connecting bridges 3 and 10 full Assembled connection assembly; the fully assembled multifunctional connection assembly can be used to connect columns and bridge frames, and can also be used to connect columns and H-shaped steel beams 7 . The fully assembled connection assembly includes 4 arc-shaped foot connectors and 4 external reinforcing ring tiles 26, and the central angles are all 90 degrees. The seams between the arc-shaped foot connectors and the seams between the column sheets are staggered from each other. The outer reinforcement ring tiles are assembled into a circular outer reinforcement ring, and the steel pipe column is tightly hooped; the arc-shaped foot connectors include A-shaped arc-sha...

Embodiment 2

[0065] The rectangular connecting feet 18 of the main-slave column energy-dissipating connecting bridge are divided into upper rectangular connecting feet, middle rectangular connecting feet and lower rectangular connecting feet. The middle rectangular connecting feet are located on both sides of the middle part of the energy-dissipating steel plate, and are provided with 4 bolt holes; the lower rectangular connecting feet are located on both sides of the lowermost part of the energy-dissipating steel plate, and are provided with two horizontal bolt holes; the rectangular connection of the arc-shaped foot connecting piece The foot 23 is provided with a bolt hole matching the rectangular connecting foot of the master-slave column energy dissipation connecting bridge.

[0066] The longitudinal lengths of the steel pipe columns are 500mm, 750mm, 1000mm and 1500mm respectively. The purpose is to stagger the four column pieces at different positions in the length direction, on the ...

Embodiment 3

[0069] like Figure 12 As shown, the difference between this embodiment and embodiment 2 is that there is 1 group of main columns forming the combined column, and 2 groups of subordinate columns, and the interval angle between the energy dissipation connecting bridge between the main column and the subordinate column is 60 degrees, there are 2 outrigger beams. All the other are identical with embodiment 2.

Abstract

The invention relates to an assembling functional restorable steel skeleton concrete combined column and an installation method, which belongs to the technical field of structural engineering. The assembling functional restorable steel skeleton concrete combined column comprises a group of steel pipe main columns, a steel pipe auxiliary column, a main and auxiliary energy consumption connecting bridge and a full-assembling connecting assembly; the full-automatic connecting assembly comprises a plurality of arc leg connecting members and a plurality of pairs of outer reinforced ring tiles, theouter reinforced ring tiles are spliced to form a circular outer reinforcing ring to tightly lock the steel tubular column; the main column and the auxiliary column are connected by utilizing the C-shaped arc leg connecting member and the full-assembling connecting assembly by virtue of the main and auxiliary column energy consumption connecting bridge to form the functional restorable steel skeleton concrete combined column; and concrete is poured into the steel tubular column. The bridge is provided with an elliptic through hole, so that the stress concentration of the bridge when in earthquake can be avoided, the absorption capability is excellent, more earthquake energy is consumed, the suffering of the main column and the auxiliary column when in earthquake can be reduced, the energyconsumption of an energy consumption component can be damaged, and the structural shock absorption performance is greatly improved.

Description

technical field [0001] The invention relates to an assembled function-restorable steel frame concrete composite column and an installation method thereof, belonging to the technical field of structural engineering. Background technique [0002] In recent years, the prefabricated steel structure building technology has advanced by leaps and bounds, and the industrialization of construction has gradually changed from a concept to a reality. With the development of society, people's requirements for architectural space are gradually increasing. Modern fabricated steel structure technology must keep pace with the times. In addition to meeting people's most basic requirements for use, it must also have more superior performance. It will not be eliminated in the rapid development trend of modern technology. [0003] At present, people's requirements for the use of buildings are mainly reflected in the larger space requirements for the structure of the building, and the structure ...
