Problems solved by technology

[0005] 1. For drilling prestressed corrugated pipes in large-diameter steel pipe columns, the prestressed corrugated pipes are easy to deflect, and the shape of prestressed tendons cannot be guaranteed.
[0006] 2. During the steel structure welding construction process, the steel structure welding slag is easy to damage the prestressed bellows
[0007] 3. When the concrete is vibrated, the vibrating rod is easy to directly contact the bellows, causing damage to it

Abstract

A prestressed corrugated pipe protection device for a large-diameter steel pipe column and its installation method, wherein the protection device includes a round steel pipe, a steel sleeve and a clamp, and the two round steel pipes are symmetrically installed on the inner side of the steel pipe column along the center of the steel pipe column to form a One group of round steel pipe groups, multiple groups of round steel pipe groups are arranged axially along the steel pipe column, the opposite end of each group of round steel pipes is provided with an opening connected with a steel sleeve and the opening has an internal thread, and the inner diameter of the steel sleeve is It is larger than the prestressed bellows, and the two sides of the steel casing are provided with a plurality of holes along the axial direction to ensure that the concrete can freely flow into the steel casing. The steel casing includes a left steel casing and a right steel casing. The far-end of left steel sleeve pipe and right steel sleeve pipe is screwed on two round steel pipes of a group of round steel pipes respectively, and the near-end of left steel sleeve pipe and right steel sleeve pipe is connected and fixed by clamp. The invention can be adapted to all construction projects in which prestressed corrugated pipes are installed in steel pipe columns, and is especially suitable for construction projects in which prestressed corrugated pipes are installed in steel pipe columns with large diameters.

Description

technical field [0001] The invention relates to the perforation construction field of a steel pipe column and a prestressed corrugated pipe of a lattice steel pipe column, in particular to an installation method for a prestressed corrugated pipe of a large-diameter steel pipe column. Background technique [0002] With the rapid development of social economy, the construction, bridge, and highway industries have also achieved rapid development. From this, a new structural system-concrete-filled steel pipe column prestressed beam-frame composite structure system has been developed to adapt to high-rise, super high-rise, long-span , Large space building needs. [0003] The technical background for the application of prestressed frame beams in concrete-filled steel tube columns is that concrete has high compressive strength and weak bending resistance, while steel, especially section steel, has strong bending resistance and good elastic-plastic properties, but it is easy to Ins...
