Description

A cast-in-place rectangular column formwork structure

technical field

The utility model belongs to the field of construction engineering, in particular to a cast-in-place rectangular column formwork structure.

Background technique

As a cast-in-place rectangular column with good vertical mechanical performance, it is favored by designers and is widely used in construction sites. The size of the rectangular column increases with the height of the building, and the speed of column formwork installation and removal is related to the main structure. During the construction progress, the rectangular columns with large cross-sections have brought certain difficulties to the horizontal support and reinforcement of the formwork, and the quality of the formwork support and reinforcement directly affects the formation of the cast-in-place structural columns. The pull bolt is an important technical measure for the support and reinforcement of the cast-in-place rectangular column formwork. Especially for the large-section rectangular column formwork, certain formwork support reinforcement measures must be taken to provide a stable formwork support system for the concrete pouring and to ensure the strength of the cast-in-place concrete. forming. However, the split bolts must be perforated in the formwork, and the perforated position is affected by the blocking of the steel bars for bolt tie reinforcement. Especially for steel reinforced concrete columns with large cross-sections, the split bolts cannot pass through the column section at all, and the reinforcement effect cannot be achieved. When the pull bolts are at the perforated position, grout leakage during the concrete pouring process is prone to occur, which affects the visual quality of the concrete structure and cannot reach the standard of fair-faced concrete.
