A prefabricated prefabricated column splicing rigid connection node and construction method

Abstract

The invention discloses an assembled prefabricated column plug-in rigid connection node and a construction method, comprising: an upper prefabricated column and a lower prefabricated column, a first connecting device is pre-embedded in the upper prefabricated column, and the first connecting device includes a first anchoring unit , the upper base plate and several upper connecting plates, the first anchor unit and the connecting plates are respectively fixedly connected on the two surfaces of the upper base plate; the second connecting device is embedded in the lower prefabricated column, and the second connecting device includes the second anchoring unit, the lower The bottom plate and several lower connecting plates, the second anchor unit and the connecting plates are respectively fixedly connected on the two surfaces of the lower bottom plate; the upper connecting plate is vertically or horizontally arranged on the upper bottom plate; Both the plate and the lower connecting plate are provided with grooves, the upper and lower connecting plates are fitted together through the grooves and interlaced with each other, and the seams of the first connecting device and the second connecting device are welded and fixed. The invention has the advantages of accurate installation and positioning, good force bearing performance, and convenient and quick on-site construction without wet operation.

Description

technical field [0001] The invention belongs to the technical field of prefabricated structural connection in construction engineering, and in particular relates to an assembled prefabricated column splicing type rigid connection node and a construction method. Background technique [0002] In recent years, with the development of urbanization and the demand for energy conservation and environmental protection, the state has vigorously developed prefabricated components in order to promote the transformation and upgrading of the construction industry. As a general prefabricated structural system, prefabricated concrete structures are widely used in engineering construction. . The advantages of the prefabricated structure lie in its short construction period, less site disturbance, more green environmental protection, and high reliability of mass production quality of components. [0003] The joints of prefabricated concrete structures (beam-column joints, column-column join...

AI Technical Summary

Problems solved by technology

Steel plate bolt connection mainly realizes the connection of prefabricated columns by connecting pre-embedded steel plates with bolts. Its disadvantages are poor seismic performance and difficult construction positioning of hoisting components.

Sleeve grouting and on-site formwork post-casting are both "wet connection". Although the mechanical performance is closest to the cast-in-place joint, the disadvantage is that the later construction operation is cumbersome and time-consuming and requires additional support protection
