Steel tube column capable of preventing concrete spillover and method for mounting steel tube column

Abstract

The invention relates to a steel tube column capable of preventing concrete spillover, which comprises a steel tube column. An annular steel plate is coaxially and fixedly mounted on the outer wall of the steel tube column, a connecting steel ring is fixedly and downwardly and vertically mounted on the periphery of the annular steel plate, and connecting rebars are evenly and fixedly mounted on the outer wall of the steel tube column below the annular steel plate. The steel tube column is simple in structure, scientific and reasonable in design and low in cost, forming time of a cast pile is shortened effectively, construction efficiency is improved, and the steel tube column is safe, reliable and capable of preventing concrete spillover.

Description

technical field [0001] The invention belongs to the field of steel pipe columns, in particular to a steel pipe column for preventing concrete overflow and an installation method thereof. Background technique [0002] During the construction of the underground part of the construction project, it is often necessary to insert a circular steel pipe column of a certain height into the cast-in-situ pile, and it is required to pour concrete into the steel pipe column. When the steel pipe and the steel cage are connected as a whole and placed in the pile hole, and then the concrete is poured, the general concrete pouring method is to insert the concrete pouring pipe from the steel pipe column into the pile hole, and then pour from bottom to top at one time Pile concrete and concrete inside steel pipe columns. Since the diameter of the steel pipe column is smaller than that of the cast-in-place pile, when this method is used for construction, the concrete outside the steel pipe col...

AI Technical Summary

Problems solved by technology

Since the diameter of the steel pipe column is smaller than that of the cast-in-place pile, when this method is used for construction, the concrete outside the steel pipe column will basically rise synchronously with the concrete inside the steel pipe column. The wrapped concrete is removed, which not only causes waste of concrete, but also requires a lot of manpower to remove excess concrete on the outer wall of the steel pipe column
