Prefabricated reinforced concrete column and column splice joint with sleeves

Abstract

The invention discloses a prefabricated reinforced concrete column and column splice joint adopting connection of embedded corrugated sleeves and high-strength reinforcement. The splice joint mainly comprises a prefabricated reinforced concrete upper column, a prefabricated reinforced concrete lower column, steel sleeves, the embedded corrugated sleeves and the high-strength reinforcement. An installation method of the splice joint comprises the following steps: in a factory, realizing the embedded high-strength reinforcement by a method of firstly pouring non-shrinkage self-compacting high-strength concrete into the embedded corrugated sleeves of the prefabricated reinforced concrete upper column and then inserting the high-strength reinforcement; and at the construction site, grouting the corrugated sleeves of the reinforced concrete lower column, inserting the embedded high-strength reinforcement of the upper column in the corrugated sleeves of the lower column and simultaneously welding the steel sleeve joint parts on the outer surfaces of the columns, thus realizing prefabricated reinforced concrete column and column splicing. The splice joint has the beneficial effects that all the used components are assembled and connected on the site, thus reducing reinforcement assembling and formwork supporting on the site, improving the building industrial assembly efficiency and reflecting the novel building concepts of environment friendliness and energy saving of building components.

Description

technical field [0001] The invention belongs to the technical field of engineering structures, and is particularly applicable to the field of on-site splicing operations between reinforced concrete columns in multi-high-rise assembled building structures. Background technique [0002] my country's building construction is mainly based on on-site construction. This traditional production method is not highly industrialized, the design and construction are relatively extensive, the quality of construction products is unstable, the construction efficiency is low, the demand for labor is large, the loss of materials and the amount of construction waste And energy consumption is relatively large, which cannot meet the sustainable development construction requirements of the national "Thirteenth Five-Year Plan" for energy conservation and environmental protection. [0003] With the acceleration of the process of "construction industrialization and housing industrialization" in my c...
