Description

A column formwork reinforcement device

technical field

The utility model relates to the technical field of construction engineering, in particular to a column formwork reinforcing device.

Background technique

Traditionally, column formwork is reinforced by using double-channel steel or double steel pipes and parallel tension screws for column formwork reinforcement. However, this method of column reinforcement is complicated, difficult to remove, and requires a lot of labor. A large number of double-channel steel or double steel pipes and parallel tension The cost of the screw is high, and if the reinforcement is not firm, there will be mold expansion, and the quality of the column is poor. Therefore, we propose a column formwork reinforcement device.
