C-shaped sleeve detachable and replaceable reinforced concrete column-column connecting structure and construction method

Abstract

The invention discloses a C-shaped sleeve detachable and replaceable reinforced concrete column-column connecting structure and a construction method. The C-shaped sleeve detachable and replaceable reinforced concrete column-column connecting structure comprises an upper reinforced concrete column, a lower reinforced concrete column, a cover plate and high-strength bolts; column end steel plates and shear-resistant connecting pieces are arranged at the column ends of the upper reinforced concrete column and the lower reinforced concrete column correspondingly; longitudinal bars and the shear-resistant connecting pieces are welded to one sides of the column end steel plates; and a C-shaped sleeve and a rectangular inner sleeve are welded to the other sides of the column end steel plates of the upper reinforced concrete column and the lower reinforced concrete column correspondingly. The C-shaped sleeve and the rectangular inner sleeve are connected through the high-strength bolts, and thus connection of the upper reinforced concrete column and the lower reinforced concrete column is achieved. The bolts are loosened, the cover plate is taken down, the column section needing to be replaced is taken down in the horizontal direction, then the new column section is pushed in the horizontal direction through hoisting, the bolts are tightened, and thus the reinforced concrete columns are detached and replaced. The C-shaped sleeve detachable and replaceable reinforced concrete column-column connecting structure is good in stress performance and convenient to machine and manufacture, the defect that a traditional steel sleeve component cannot be flexibly detached and replaced in the service period is overcome, and a new thought is provided for connection of a detachable and replaceable structure system in the whole life cycle.

Description

technical field [0001] The invention relates to the field of column-column connection in a detachable and replaceable structural system in the whole life cycle, in particular to a C-shaped sleeve detachable and replaceable reinforced concrete column-column connection structure and method. Background technique [0002] With the rapid development of my country's economic level and construction industry, the disadvantages of traditional building structures are gradually highlighted. For example, a large amount of construction waste, dust and noise are generated during new construction, reconstruction, expansion and demolition, resulting in waste of resources and endangering the ecological environment. Since the 21st century, with the continuous development of the concept of low-carbon economy, prefabricated structures have gradually emerged, which has effectively solved the problems of large construction noise, large construction waste output, and long construction period. It s...
