Prestressed steel bar tensioning equipment

Abstract

A prestressed steel bar tensioning equipment comprises embedded seats, anchor seats, a driving mechanism, a tensioning plate and a synchronous control system, the two embedded seats are embedded underground on the two sides of a bench formwork respectively, the two anchor seats are fixed to the two embedded seats respectively, the tensioning plate comprises a first end and a second end, and the driving mechanism comprises a driving station, a first telescopic piece and a second telescopic piece. A driving piece is connected with the first telescopic piece and the second telescopic piece, the telescopic ends of the first telescopic piece and the second telescopic piece are connected with the first end of the tensioning plate, and the second end of the tensioning plate is in butt joint with the adjacent anchor seat. The synchronous control system comprises sensors and a controller which are electrically connected, the two sensors are arranged in the first telescopic piece and the second telescopic piece respectively and used for detecting telescopic displacement data of the first telescopic piece and the second telescopic piece in real time, and the controller is used for receiving detection data of the sensors and controlling operation of the driving mechanism. According to the prestressed steel bar tensioning equipment, it can be guaranteed that two oil cylinders work synchronously, tensioning displacement can be accurately guaranteed, and intelligent control can be achieved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated component production, and in particular relates to a prestressed steel bar tensioning device. Background technique [0002] Prestressed concrete is a kind of reinforced concrete that exerts a certain pressure in the tensile area of ​​the member before the reinforced concrete member bears the load, so that the concrete produces a certain compression deformation, referred to as prestressed concrete. For laminated slabs / prefabricated slabs, there will be downward bending deformation under gravity and load during use. In order to reduce this deformation, a certain tension can be applied to the tendons in the laminated slabs / prefabricated slabs. Concrete is prestressed to form prestressed laminated slabs / precast slabs. Compared with ordinary laminated panels / prefabricated panels, prestressed laminated panels / prefabricated panels have better bending resistance and longer service life. [0003] T...
