Fish-bellied beam steel strand and supporting beam adjusting base, fish-bellied beam system and construction method

Abstract

The invention provides a fish-bellied beam steel strand and supporting beam adjusting base, comprising two steel sliding grooves, a sliding piece, a rotating shaft and a wire passing pipe, the steel sliding grooves are C-shaped components, and the two steel sliding grooves are formed in H-shaped grooves of an H-shaped steel supporting beam in the back direction. The sliding piece comprises a sliding rod matched with the steel sliding grooves. The rotating shaft is inserted into the sliding piece and is hinged to the sliding piece. A steel strand is sleeved with the wire passing pipe, the side,close to the H-shaped steel supporting beam, of the wire passing pipe is fixedly connected with a rotating base, the rotating base is fixedly connected with the two ends of the rotating shaft, the rotating base is hinged to the sliding piece through the rotating shaft, and then the wire passing pipe is hinged to the sliding piece. The adjusting base is applied to a fish-bellied beam system, prestress is conveniently applied to the steel strand, abrasion and wire breakage of the steel strand are avoided, the construction danger coefficient is reduced, the service life of the prestress steel strand is prolonged, meanwhile, the construction progress can be improved, and the construction cost is reduced.

Description

technical field [0001] The invention specifically relates to the field of foundation pit support methods, in particular to an adjustment seat for fish-belly beam steel strands and support beams, a fish-belly beam system and a construction method. Background technique [0002] With the rapid development of our country's economy, the urban ground space is becoming increasingly tense, and the three-dimensional urban space has begun to be developed as an important natural resource. The extensive construction of underground facilities, underground logistics, underground energy and material storage and other facilities has brought a huge market space to the construction technology of fabricated prestressed fish-belly beam steel supports. [0003] However, the steel strand at the end of the existing fish-belly beam structure is easy to wear and break, which seriously shortens the service life of the steel strand, which is very likely to endanger the life safety of construction work...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an adjustment seat for fish-belly beam steel strands and supporting beams, a fish-belly beam system and a construction method to solve the problem that the steel strands at the end of the existing fish-belly beam structure are easy to wear, broken wires, and seriously shortened. The service life of the steel strand is shortened, which is very likely to endanger the life safety of the construction personnel, and also affects the technical problems of the construction progress.
