Abstract

The invention discloses a tensioning stress linkage stretching device for beam body machining, relates to the technical field of beam body machining, and solves the problems that in the manufacturingprocess of an existing assembled prestress concrete beam, main reinforcements cannot be synchronously stretched at the same time, stress between the main reinforcements is uneven, and the subsequent use quality is affected. The tensioning stress linkage stretching device for beam body machining comprises a tensioning fixing plate. The tensioning fixing plate is inserted into the outer side of a tensioning supporting plate. According to the device, main beam steel bars can be positioned in a positioning through groove of a tensioning fixing plate through a main bar fixing mechanism, and a tensioning adjusting rod is rotated to drive a tensioning linkage plate to move towards the tensioning fixing plate to compress a tensioning ejection spring to tension and apply prestress to the main beamsteel bars; and corresponding prestress can be synchronously applied to all the main beam steel bars at the same time.

Description

technical field

[0001] The invention belongs to the technical field of beam body processing, and more specifically relates to a tension stress linkage stretching device for beam body processing. Background technique

[0002] At present, prestressed concrete components are widely used in construction projects. Prestressed concrete is to make up for the phenomenon of premature cracks in concrete. Inside, the steel bars are stretched by means of artificial reinforcement, and the tension area of ​​the concrete is pre-stressed by using the retraction force of the steel bars. This stored preloaded pressure, when the member bears the tensile force generated by the external load, first offsets the preloaded pressure in the concrete in the tension area, and then the concrete is stretched as the load increases, which limits the elongation of the concrete. Delaying or not making cracks appear, this is called prestressed concrete.

[0003] For example, in the patent with the applicati...
