Example Embodiment

[0029] See Figure 1 to Figure 4 As shown, a splicing structure of a prefabricated concrete-filled steel tubular column and a column includes two concrete-filled steel tubular columns arranged up and down. Several steel bars 3 are embedded in the upper CFST column 1, and part of the steel bars 3 extend downward from the bottom surface of the upper CFST column 1; Lower the top surface of CFST column 2. Concrete slurry is injected into the corrugated casing 4 and the steel bars 3 are inserted into the corrugated casing 4 in one-to-one correspondence, so that the bottom surface of the upper CFST column 1 is connected to the top surface of the lower CFST column 2, and the butt joint parts of the steel pipe are welded at the same time. Realize the splicing of two concrete-filled steel tubular columns.

[0030] The steel bar 3 is arranged parallel to the axis of the upper CFST column 1, the corrugated sleeve 4 is arranged parallel to the axis of the lower CFST column 2, and the up...

Abstract

The invention discloses an assembled concrete filled steel tubular column splicing structure and method. The assembled concrete filled steel tubular column splicing structure comprises prefabricated upper and lower concrete filled steel tubular columns, steel bars are embedded in the upper concrete filled steel tubular columns, and corrugated casing pipes are embedded in the upper concrete filled steel tubular columns. After the reserved corrugated casing pipes are filled with concrete grout in a constructions site, the embedded steel bars in the upper concrete filled steel tubular columns are inserted into the corrugated casing pipes to make the upper concrete filled steel tubular columns arranged on the lower concrete filled steel tubular columns and in butt joint with the lower concrete filled steel tubular columns, and then steel pipe connecting parts are welded to achieve concrete filled steel tubular column splicing. All the members used in the structure are assembled and connected in the site, a site formwork project and welding work are decreased, the industrialized assembling efficiency of a building is improved, and the energy-saving and environmentally friendly building design concept for sustainable development of building members is embodied.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a splicing structure and method of fabricated steel pipe concrete columns and columns. Background technique [0002] With the rapid development of urbanization in China, the traditional reinforced concrete structure is no longer in line with the "applicable" policy promoted by the state due to its shortcomings such as large environmental pollution, high material and energy consumption, serious environmental pollution and low recycling rate of building materials. , Economical, Green and Beautiful" architectural policy. In order to seek the development of new construction methods, promote prefabricated concrete, steel structures and other building systems suitable for industrial production, accelerate the development of prefabrication and assembly technology for construction projects, and improve the integration level of construction industrialization technology. Su...
