Abstract

The invention discloses a multilayer carbon fiber cloth tensioning and anchoring device and method for concrete structure reinforcing. The device comprises a fixing end anchorage device, a tensioning end anchoring device and a combined tensioning end anchorage device. The combined tensioning end anchorage device can be split into a wedge-shaped anchoring end and an anchorage device top end. The two ends of multilayer carbon fiber cloth are clamped through the fixing end anchorage device and the combined tensioning end anchorage device, tension is applied to the tensioning end anchoring device through a jack, and a guide rod connected with the tensioning end anchoring device is used for carrying out prestress tensioning and anchoring on the multilayer carbon fiber cloth. The characteristics that carbon fibers are light and high in strength can be fully exerted, the strength utilization rate of the carbon fibers is obviously increased, stress and flexural deformation of the concrete structure are effectively reduced, beam cracking is delayed, the width of cracks is reduced, and the bearing capacity of the structure is further improved.

Description

technical field [0001] The invention belongs to the related technical field of prestressed reinforced concrete, and proposes a multi-layer carbon fiber cloth tensioning and anchoring device and method for reinforcing concrete structures, which are suitable for clamping and anchoring of infrastructure engineering structures such as civil engineering and water conservancy. Background technique [0002] As a new type of concrete reinforcement technology, prestressed carbon fiber tape anchoring technology has good development prospects. It can give full play to the characteristics of light weight and high strength of carbon fiber, greatly improve the strength of concrete structures, and effectively reduce its stress and deflection deformation. The beam cracking speed is delayed, the crack width is reduced, the bearing capacity of the structure is further improved, and its durability is improved. At present, the prestressed carbon fiber cloth tension anchor system developed at ho...
