Description

Technical Field

[0001] This utility model relates to a tensioning device for coplanar carbon fiber plates, belonging to the field of construction technology. Background Technology

[0002] Carbon fiber anchoring devices are a key technology in construction engineering, used to enhance structural performance and improve building stability. They are primarily used to reliably fix carbon fiber composite materials to the surface of concrete, steel, or other substrates, thereby achieving structural reinforcement or strengthening. Carbon fiber anchoring devices securely fix carbon fibers to the surface of building components through mechanical clamping, chemical bonding, or a combination of both. Under load, the carbon fibers and the substrate share the force, thus dispersing stress concentration and improving the structure's load-bearing capacity and seismic performance. For example, a prestressed carbon fiber tensioning device is disclosed in Chinese patent document CN209923796U. Figure 1 As shown, the structure includes a fixed-end base 100, a fixed-end anchor block, a carbon fiber tension cable 3, a tensioning-end anchor block, and a tensioning-end base 500. The fixed-end anchor block and the tensioning-end anchor block are respectively fixed to both ends of the tension cable 3. The tensioning-end anchor block is set in the groove of the tensioning-end base 500 and can slide linearly in the groove. The tensioning-end anchor block is connected to one end of a screw rod 600. The other end of the screw rod 600 passes through a through hole in the tensioning-end base 500, a stop nut 700, a jack baffle 800, and a tensioning nut 900 in sequence. The stop nut 700 and the tensioning nut 900 are screwed onto the screw rod 600. One end of the jack 801 rests on the jack baffle 800, and the other end rests on the tensioning-end base 500. Because the tension cable 3 needs to be in close contact with the surface of the building component, the center line of the thrust applied by the jack 801 must be coplanar with the screw 600. Due to the large size of the jack, the screw 600 cannot be coplanar with the tension cable 3. As a result, both the screw 600 and the tension cable 3 in the final anchoring structure formed after tensioning are subject to complex forces, which reduces the overall anchoring effect of the anchor.
