Description

Technical Field

[0001] The utility model relates to the technical field of structural columns, in particular to a chiseling-free device for a dustpan opening of a structural column. Background Art

[0002] During the construction of the existing structural column, a dustpan opening is first opened at the top of the column for pouring. After pouring, the concrete in the dustpan opening is used to press the structural column so that the top of the structural column is fully filled. After the construction of the existing structural column dustpan opening is completed, the template is removed after the concrete is dry, and then the excess concrete from the dustpan opening is chiseled out. Due to the large volume of the excess concrete and the high hardness of the concrete, the construction is time-consuming and labor-intensive, and the practicality is low.

[0003] Therefore, there is a device for preventing the dustpan mouth of a structural column from being chiseled, which adopts a lifting plate to isolate the concrete between the structural column and the dustpan plate. However, the existing lifting plate completely isolates the concrete between the structural column and the dustpan plate, resulting in that during the solidification process, the concrete in the dustpan cannot enter the position of the structural column to be cast, resulting in the top of the structural column being not cast compactly, a honeycomb hole appearing on the top of the structural column, and poor firmness.

At the same time, it prevents the lifting plate from completely isolating the concrete between the structural column and the dustpan plate, resulting in the concrete of the dustpan plate being unable to enter the position of the structural column to be cast during the solidification process, resulting in the problem of honeycomb holes and poor firmness, thereby improving the reliability of use.
