Problems solved by technology

At present, the research on prefabricated outsourcing steel concrete column joints at home and abroad is mainly the cast-in-place technology. The cast-in-place method is a relatively mature technology. The integrity of the cast-in-place structure is strong, but it requires a lot of formwork and maintenance time during the construction process. Long, waste a lot of materials, pollute the environment and the project quality is uneven, etc.

Abstract

The invention discloses a prefabricated steel-encased concrete spliced column and construction process. The prefabricated steel-encased concrete spliced column is divided into three connection forms.The first connection form is end plate connection, the prefabricated steel-encased concrete spliced column comprises an upper column section and a lower column section, the lower column section and the upper column section are both prefabricated steel-encased concrete columns, or the lower column section is a prefabricated steel-encased concrete column, and the upper column section is a prefabricated reinforced concrete column; the second connection form is bolting splicing, the prefabricated steel-encased concrete spliced column comprises an upper column section and a lower column section, the lower column section and the upper column section are the same in structure and are both prefabricated steel-encased concrete columns, or the lower column section is a prefabricated steel-encased concrete column, and the upper column section is a prefabricated reinforced concrete column; the third connection form is grouting sleeve connection, the prefabricated steel-encased concrete spliced column comprises an upper column section and a lower column section, the lower column section and the upper column section are both prefabricated steel-encased concrete columns, or the lower column section is a prefabricated steel-encased concrete column, and the upper column section is a prefabricated reinforced concrete column. Due to the splicing joint form of the prefabricated steel-encased concrete spliced column, the prefabricated spliced column has strength, rigidity and good anti-seismic property.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a prefabricated outsourcing steel-concrete splicing column and a construction process. Background technique [0002] Nowadays, in order to meet the increasing upper load of traditional reinforced concrete columns, the section size has to be increased, which will affect the use of the structure to a certain extent. Therefore, in order to solve this problem, outsourcing steel and concrete structures have been gradually developed. The steel-clad concrete structure is a concrete structure with profiled steel externally. The main stress bars in the component are replaced by profiled steel, which are generally placed at the four corners or bottom of the component. Steel plates or angle steel are generally used for the externally clad profiled steel. The section steel in the steel-clad concrete structure improves the shear resistance of the component, and the se...
