Splicing structure of fabricated concrete-filled steel pipe column

Abstract

The invention relates to the related field of constructional engineering, in particular to a splicing structure of a fabricated concrete-filled steel pipe column. The splicing structure of the fabricated concrete-filled steel pipe column comprises an upper steel pipe column, a splicing shell and a lower steel pipe column. According to the splicing structure of the fabricated concrete-filled steel pipe column, the splicing shell, a connecting and fixing rod, an upper sealing plate and a lower sealing plate used in the splicing structure are all processed in a factory and can be assembled and connected on a construction site after being transported to the construction site, on-site welding work and formwork work are reduced, the on-site construction quality is guaranteed, and the building industrial assembly efficiency is improved; second reinforcing ribs are connected to the upper end and the lower end of a mounting frame, the top ends of the second reinforcing ribs are arranged in the upper steel pipe column and the lower steel pipe column, a plurality of arc-shaped grooves are evenly formed in the surfaces of the second reinforcing ribs, and first reinforcing ribs are horizontally welded to the inner cavity walls of an upper splicing groove and a lower splicing groove in parallel, so that the second reinforcing ribs and the first reinforcing ribs are better adhered to concrete when the concrete is poured, so that the bearing capacity and the deformability of the concrete-filled steel pipe column are improved.

Description

technical field [0001] The invention relates to the related fields of construction engineering, in particular to a splicing structure of fabricated steel pipe concrete 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. Support the construction...
