Description

Technical Field

[0001] The utility model relates to the field of structural reinforcement and maintenance of infrastructure, in particular to a flexible reinforcement device. Background Art

[0002] During the maintenance and construction of large structures such as bridges, tunnels, and buildings, flexible materials are used on the outside of the structure to provide prestress for the structure, thereby providing the structure with bearing capacity. Common flexible materials used for infrastructure reinforcement are carbon fiber reinforced composite fabrics, which are mainly fixed to the structure by bonding.

[0003] With the existing flexible material reinforcement method, after the flexible material is bonded to the structure to be reinforced, its tightening degree cannot be changed, and the prestress provided for the structure cannot change with subsequent needs, which is inconvenient for subsequent maintenance. Utility Model Content

[0004] In order to solve the above problems, the utility model provides the following technical solutions:

[0005] A flexible reinforcement device, comprising:

[0006] An adjustable fixing assembly includes a plurality of fixing anchor heads, a winding adjustment portion provided on the fixing anchor heads, and a fixing installation structure capable of installing the fixing anchor heads on an external object;

[0007] The end of the flexible connector is connected to the winding adjustment part on the fixed anchor head. The winding adjustment part can wind up the flexible connector, and the winding adjustment part can only rotate in one direction.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the winding adjustment part includes a winding shaft arranged on the surface of the fixed anchor head, and a one-way locking structure arranged between the winding shaft and the fixed anchor head.

[0010] Furthermore, a protrusion for the winding shaft to be installed is provided on the surface of the fixed anchor head, and a gap for the flexible connecting member to pass through is reserved between the fixed anchor head and the winding shaft.

[0011] Furthermore, the protrusions provided on the surface of the fixed anchor head are plate-like structures, and the number of the protrusions is at least two.

[0012] Furthermore, positioning blocks are provided between the protrusions provided on the surface of the fixed anchor head, and a gap is left between the positioning blocks and the anchor head for the flexible connector to pass through.

[0013] Furthermore, the one-way locking structure includes a ratchet wheel disposed on the surface of the winding shaft close to the end, and a pawl disposed on the surface of the anchor head, wherein the pawl contacts the surface of the ratchet wheel and is mounted on the surface of the anchor head via a detachable mounting structure.

[0014] Furthermore, the surface of the winding shaft is provided with an opening for the flexible connector to pass through, and an end stopper is provided at one end of the flexible connector close to the winding shaft, and the end stopper as a whole cannot pass through the opening provided on the surface of the winding shaft.

[0015] Furthermore, the fixed installation structure includes a fixed plate and a connecting piece capable of connecting the fixed plate and the fixed anchor head together, and anti-slip grooves are provided at the opposite positions of the fixed plate and the fixed anchor head.

[0016] Beneficial Effects

[0017] Compared with the prior art, the utility model, through the adjustable fixing assembly and the flexible connector, can tighten the flexible connector via the winding adjustment part during use. In the process of reinforcing the external infrastructure, the tightening degree of the flexible connector can be adjusted according to the use requirements to adapt to different prestressing requirements. During the later maintenance, since the flexible connector is not directly bonded to the infrastructure, the operator can remove the fixed anchor head to achieve rapid disassembly of the flexible connector and facilitate later maintenance.
