Embodiment Construction

[0029] See Figure 1 to Figure 4 As shown, a splicing structure of prefabricated concrete-filled steel tube columns and columns, including two concrete-filled steel tube columns arranged one above the other. A number of steel bars 3 are pre-embedded in the upper concrete-filled steel pipe column 1, and part of the steel bars 3 extends downward out of the bottom surface of the upper concrete-filled steel pipe column 1; a number of corrugated sleeves 4 are embedded in the lower steel-filled steel tube concrete column 2, and one end of the corrugated sleeve 4 is exposed to the The top surface of the lower concrete filled steel pipe column 2. Concrete slurry is injected into the corrugated casing 4 and the steel bars 3 are connected to the corrugated casing 4 one by one, so that the bottom surface of the upper concrete-filled steel tube column 1 is connected to the top surface of the lower steel-filled steel tube concrete column 2. Realize the splicing of two steel pipe concrete ...

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...
