Energy-saving and environment-friendly rigidity improving assembly for steel bar prestress

Abstract

The invention relates to the technical field of steel bar prestress, and discloses an energy-saving and environment-friendly steel bar prestress rigidity improving assembly. The energy-saving and environment-friendly rigidity improving assembly for steel bar prestress comprises a control shaft; a detection block is fixedly connected to the outer side of the control shaft; a conical plate is fixedly connected to the top of the detection block; a synchronous disc is fixedly connected to the top of the conical plate; and outer side teeth are fixedly connected to the outer side of the synchronousdisc. According to the energy-saving and environment-friendly rigidity improving assembly for steel bar prestress, the synchronous disc synchronously rotates along with the control shaft through centrifugal force of the control shaft, a trigger block makes contact with a linkage bin under the action of the centrifugal force, a rolling ball extrudes the outer wall of a rotating ring under the action of the centrifugal force, a movable ball connected to the outer wall of the rotating ring is stressed to be hardened, the size of the movable ball is increased, an extrusion plate and a limiting plate are pushed to move outwards, stall of the control shaft is controlled, excessive stretching of a reinforcing steel bar is reduced, and the mechanical fatigue degree of the reinforcing steel bar isreduced.

Description

technical field [0001] The invention relates to the technical field of steel bar prestressing, in particular to a lifting stiffness component for steel bar prestressing based on energy saving and environmental protection. Background technique [0002] Reinforcement prestressing refers to applying tension to the reinforcement first, and then pouring concrete. After the strength reaches the requirement, the reinforcement is loosened, so that the reinforcement retracts, and the tension of the normal load is offset, so that the strength of the reinforcement in the reinforced concrete member is fully utilized, and then strengthened. The overall construction strength of the building, so that the safety of the building is improved. [0003] The publication number is CN207453486U, and the publication date is June 5, 2018. The Chinese patent discloses a steel prestressing machine whose structure includes concrete, grooves, prestressed steel bars, anchors, tension boxes, fixing parts,...
