Prefabricated T-beam web steel bar integral hoisting auxiliary device

Abstract

The invention discloses a prefabricated T-beam web steel bar integral hoisting auxiliary device which comprises main trusses, web members, hoisting point structures and a load-bearing system. The main trusses are connected through the web members by adopting steel pipes with the outer diameter phi of 108 mm and the wall thickness of 4 mm, the web members adopt steel pipes with the outer diameter phi of 48.3 mm and the wall thickness of 3.6 mm, the hoisting point structures are symmetrically arranged at the two sides of the main trusses C by adopting round steel with the diameter phi of 20 mm, the load-bearing system is arranged in the center of the horizontal web member by adopting 200 mm channel steel, a steel strand penetrates through T-beam web steel bars, the steel strand is connected with the load-bearing system through a steel wire rope, the lifting point structures are connected with the main trusses C in a lap welding manner, and the length of a welding seam is not less than 200 mm. By means of the method, when the T-beam web steel bars are hoisted, the web steel bars are not prone to deformation as a whole through the rigidity characteristic of the main trusses, influences on follow-up construction are avoided, meanwhile, the quality of a T-beam is guaranteed, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of bridge superstructure construction, in particular to a prefabricated T-beam web reinforcement integral hoisting auxiliary device. Background technique [0002] With the rapid development of my country's infrastructure industry, the requirements for all aspects of bridge construction are getting higher and higher. Prefabricated T-beams are used as control parts in bridge engineering. The quality of T-beams is often closely related to the quality of bridge structures. Nowadays, most T-beam webs The plate reinforcements are all required to be bound on the film frame, and then the whole is hoisted to the beam-making pedestal for subsequent construction. When lifting the web reinforcement, the use of conventional methods often easily leads to local deformation of the web reinforcement and increases the subsequent construction period. Seriously, it is easy to cause rework, which greatly restricts the construction...
