Prestress releasing construction clamping sheet shifting device and shifting method thereof

Abstract

The invention discloses a prestress releasing construction clamping sheet shifting device and a shifting method thereof. The prestress releasing construction clamping sheet shifting device comprises clamping components distributed in the circumferential direction and gear rings arranged on the peripheries of the clamping components, wherein the clamping components are in an arc shape, the adjacent clamping components are connected in an embedded mode, and racks extending towards the gear rings are fixedly arranged on the clamping components; the joints of the racks and the gear rings are meshed with coaxial combined gears, the racks are meshed with upper gears of the combined gears, the gear rings are meshed with lower gears of the combined gears, and cylindrical anchor withdrawing devices are arranged in the gear rings; long grooves capable of containing the combined gears are vertically formed in the positions, corresponding to the combined gears, of the cylinder walls of the anchor withdrawing devices, and sliding rods penetrating through middle shafts of the combined gears are fixedly arranged at the two ends of the long grooves. The shifting device for conveniently releasing clamping sheets in prestress construction and the shifting method of the shifting device are provided so as to solve the construction difficulty caused by the limited operation and sight line of the traditional prestress construction.

Description

technical field [0001] The invention relates to the technical field of prestressed construction, and in particular to a prestressed tension release construction clip toggle device and a toggle method thereof. Background technique [0002] At present, in the process of prestressing construction, due to various reasons, it is necessary to perform tensioning treatment on the steel strands that have been stretched. The tensioning process is generally as follows: After the jack is pre-extended for a certain length, the steel strands are pulled outward, slowly After pressurizing until the clip is loose, move the clip backward with a tool, and then release the tension on the steel strand. When releasing the tension, the jack is mostly a front clamping jack, and the front end is equipped with a metal cylinder anchor retractor with a large opening on the side as an auxiliary tool. This construction method has the following disadvantages: (1) Since the steel strands mostly have multi...
