Tensioning device for applying pretensioning force to fiber cloth materials and tensioning method of tensioning device
The invention discloses a tensioning device for applying a pretensioning force to fiber cloth materials and a tensioning method of the tensioning device. The tensioning device comprises a slide way (11), wherein a rolling groove (2) is arranged in the slide way (11) and can freely slide in the slide way (11); two rolling shafts (4) are arranged in the rolling groove (2), can roll along the horizontal direction of the rolling groove (2), and is used for winding the fiber cloth materials so that the fiber cloth materials are locked and fixed; an opening (8) is formed in an upper flange of the rolling groove (2); a base plate (3) is arranged at a position, which is close to the upper flange of a tensioning end, of the rolling groove (2); an L-shaped baffle (5) is arranged at the tensioning end of the rolling groove (2) and is abutted to the rolling shafts (4); and by the L-shaped baffle (5), end rigidity is improved. A fiber cloth material anchoring effect is excellent, through displacement control loading after tensioning, the outer end of a bolt bar is connected with a sensor, magnitude of a tensioning force can be measured directly, the problem that when fiber cloth materials are tensioned by another device, force is difficult to measure is solved, the fiber cloth materials are wound on the rolling shafts, and the problem that the fiber cloth materials cannot be stressed evenly is solved.
