An object of the utility model is to provide a cable membrane structure cable tensioning equipment. The problem that the tension stress is difficult to control in the process of applying tension to the cable membrane structure stay cable is solved.
The utility model discloses a: the device comprises a fixed steel box 1, a sliding steel box 2, a fixed screw 3, a first nut 4, a second nut 5, a screw connecting plate 6, a pin shaft 7, a stud 8, a third nut 9, a jack 10 and a pressure sensor 11. The fixed steel box 1 and the sliding steel box 2 are connected through a fixed screw 3, a first nut 4 and a second nut 5; the sliding steel box 2 is connected through a stud 8 and a third nut 9; the fixed screw 3 is connected with a screw connecting plate 6 through a pin shaft 7; the jack 10 and the pressure sensor 11 are placed between the fixed steel box 1 and the sliding steel box 2 to be tightly jacked.
The sliding steel box 2, the second nut 5, the fixed steel box 1 and the first nut 4 sequentially penetrate into the fixed screw rod 3 and are connected in an assembled mode.
The sliding steel box 2 is fixedly connected through the stud 8 and the third nut 9 and clamps the steel cable lock head 12, so that tension can be applied conveniently.
The fixing screw rods 3 are arranged in a quadrilateral symmetrical mode, and the uniform stress of the inhaul cable is guaranteed.
The screw connecting plate (6) is welded with the embedded part (15), and the screw connecting plate (6) can not be detached after tensioning is completed, so that convenience is brought to later maintenance.
The fixed steel box 1 and the sliding steel box 2 are formed by welding steel plates; the fixed screw 3 is formed by welding a lead screw and a connecting plate; the screw connecting plate 6 is made of a steel plate.
The utility model has the advantages that: the cable membrane structure cable tensioning device is simple in structure, convenient to install and disassemble and suitable for cable membrane structure cable tensioning construction. The fixing screws are symmetrically arranged in a quadrilateral mode, so that the stress of the stay cable is uniform, the tension is monitored by using the pressure sensor, and the cable membrane is not easy to damage when being stretched. The screw rod connecting plate can not be disassembled after tensioning is completed, and convenience is provided for later maintenance.
