Self-balancing inner support structure of large-diameter thin-wall circular pipe, and support method thereof

Abstract

The invention provides a self-balancing inner support structure of a large-diameter thin-wall circular pipe, and a support method thereof. The structure comprises a middle core piece, two support kitsand a pushing piece, wherein the middle core piece comprises a connecting middle section and two end heads detachably connected to two ends of the connecting middle section; each support kit comprises two arc-shaped pieces used for being supported on the inner wall of the large-diameter thin-wall circular pipe and arranged oppositely, and two support rods respectively hinged to the arc-shaped pieces; the support rods of the two support kits are respectively connected to two ends of the connecting middle section; the arc-shaped pieces of the two support kits are alternately arranged in the circumferential direction of the large-diameter thin-wall circular pipe and are arranged in the length direction of the connecting middle section at intervals; and two opposite ends of the pushing pieceare respectively hinged to each end head and the corresponding support rod at one same end of the middle core piece. The self-balancing inner support structure of the large-diameter thin-wall circularpipe provided by the invention solves the problem that a traditional liner circular ring support of the thin-wall circular pipe is easy to slide and incline.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a self-balancing inner support structure of a large-diameter thin-walled circular pipe and a support method thereof. Background technique [0002] For the large-diameter thin-walled ribless circular tube structure, it is easy to deform due to its insufficient rigidity during transportation or storage. The traditional lining ring support of the round pipe is not easy to install in the center of the round pipe, and the ring itself is easy to slide and tilt sideways, so the support reliability is not enough. Contents of the invention [0003] In order to overcome the defects existing in the prior art, a self-balancing internal support structure and a supporting method for a large-diameter thin-walled circular pipe are provided to solve the problem that the traditional lining ring support of the thin-walled circular pipe is easy to measure and slide.
