Tension-controllable carbon fiber cloth tensioning device

Abstract

The invention provides a tension-controllable carbon fiber cloth tensioning device, and belongs to the technical field of carbon fiber cloth tensioning devices. The device comprises a fixing frame body, guide rods, adjusting pieces, a guide shaft, supporting rods and a chain wheel moving device. The chain wheel moving device is connected to the guide rods through the supporting rods, the guide shaft is movably connected to the guide rods through the adjusting pieces, and the guide rods are rotatably connected to the fixing frame body. According to the tension-controllable carbon fiber cloth tensioning device, a different angle is formed between the guide rods and the guide shaft is adjusted, the tensioning device is not only suitable for reinforcing a horizontal structure, but also can besuitable for structures of different angular shapes, compared with an existing tensioning device, the tensioning device is wider in application range, the utilization rate of the device is greatly improved, moreover, in a using process, carbon fiber cloth can be appropriately bonded to a certain-shape structure to a greater extent, the high-strength characteristic of the carbon fiber cloth is fully exerted, and a better reinforcing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of carbon fiber cloth tensioning devices, in particular to a carbon fiber cloth tensioning device with controllable tensioning. Background technique [0002] Because of its high strength, low density, thin thickness and light weight, carbon fiber cloth is widely used in the reinforcement, repair and earthquake resistance of various structures in the construction industry. Among them, carbon fiber cloth reinforcement is mainly divided into prestressed and non-prestressed, non-prestressed Stress reinforcement is mainly to adhere the carbon fiber cloth to the structure that needs to be reinforced through the bonding system. Prestress reinforcement is to apply a certain prestress to the carbon fiber cloth by using a tensioning device on the basis of non-prestressed, and to achieve the correct effect through the anchoring and pasting process. Compared with non-prestressed reinforcement, prestressed reinforcement ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing tensioning devices are generally not adjustable, and are only suitable for horizontal structure reinforcement, and are not suitable for some structures with a certain angle shape, resulting in a narrow application range of the tensioning device, low utilization rate, or During the process, the carbon fiber cloth cannot be properly fixed in the structure that needs to be reinforced, so that the high-strength characteristics of the carbon fiber cloth cannot be fully utilized, thereby affecting the reinforcement effect. There are also a small number of adjustable tensioning devices that can be used. It is suitable for some structures with a certain angle shape, but its adjustable range is narrow, and the applicable range is relatively not very high
