Through the cooperation of the power connection mechanism and the connecting block, the pressing pressure on the carbon fiber board is gradually increased to ensure that it is stable and fixed during the tensioning process.
By gradually increasing the pressing pressure, the carbon fiber board is prevented from disengagement caused by the increase in deformation during the tensioning process, and the stability of the prestressed carbon fiber board reinforcement equipment during the tensioning process is improved.

Technical Field
[0001] The utility model relates to the technical field of carbon fiber plate application, in particular to a prestressed carbon fiber plate reinforcement device. Background Art
[0002] Prestressed carbon fiber plate, full name prestressed carbon fiber plate reinforcement system, is a reinforcement material designed specifically for reinforcing reinforced concrete bending, tension and large eccentric compression members with small cross-section or insufficient reinforcement.
[0003] In order to improve the bearing capacity and durability of concrete, tensioning prestressed carbon fiber panels is a commonly used reinforcement method. However, in practical applications, especially during bidirectional tensioning, the initial pressing force applied by the reinforcement device to the prestressed carbon fiber panels may not be sufficient to cope with the movement of the carbon fiber panels under gradually increasing deformation forces. Once the deformation force exceeds the initial pressing force, the prestressed carbon fiber panels may detach from the reinforcement device, resulting in failure of tensioning fixation. Therefore, it is necessary to design a prestressed carbon fiber panel reinforcement device that gradually increases the pressing force capacity during the tensioning process of the carbon fiber panels.

It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0018] See also Figure 1-4 The utility model provides a technical solution: a prestressed carbon fiber plate reinforcement device, comprising a fixed shell 1 of a concave structure, the tops of both sides of the fixed shell 1 are provided with connecting bolts 2, and the rear inner wall of the fixed shell 1 is slidably provided with a gradual reinforcement mechanism for fixing the prestressed carbon fiber plate;
[0019] A connection block 4 for connecting a power source is fixedly mounted on the right end of the step-by-step reinforcement mechanism, and the connection block 4 is movably connected to a power connection mechanism for power output.
[0020] Specifically, the step-by-step reinforcement mechanism includes a horizontal slot 3, which is provided on the rear inner wall of the fixed shell 1, and is movably connected with a movable block 31, and a movable base plate 32 is fixedly installed at the front end of the movable block 31. An inclined slot 33 is provided on the rear inner wall of the fixed shell 1 and located on the upper side of the horizontal slot 3, and is movably connected with an inclined block in the inclined slot 33, and a movable pressing plate 34 is rotatably connected to the front end of the inclined block. The right sides of the movable base plate 32 and the movable pressing plate 34 are fixedly installed with connecting blocks 4, and the movable base plate 32 and the movable pressing plate 34 are movably sleeved with a fixing screw 35 for limiting the prestressed carbon fiber plate, and the fixing screw 35 is threadedly connected with a stabilizing nut 36.
[0021] In this embodiment, by gradually reinforcing the cooperation between the mechanisms, the pressing force on the prestressed carbon fiber plate is gradually increased while tensioning the prestressed carbon fiber plate. The corresponding relationship between the inclined height difference of the inclined slot 33 and the tensioning distance of the prestressed carbon fiber plate can be calculated.
[0022] Specifically, the power connection mechanism includes a connecting slot plate 41, which is movably connected to the connecting block 4. A fixed threaded rod 42 is fixedly installed on the right side of the connecting slot plate 41. The fixed threaded rod 42 is threadedly connected to a pulling threaded tube 43, and a hexagonal power connection block 5 is fixedly installed on the right end of the pulling threaded tube 43.
[0023] In this embodiment, the cooperation between the power connection mechanisms facilitates disassembly while also providing tensioning and pressing power for the movable bottom plate 32 and the movable pressing plate 34 .
[0024] Specifically, there are a plurality of fixing screws 35 and stabilizing nuts 36 , and the plurality of fixing screws 35 and stabilizing nuts 36 are linearly and evenly arranged on the front and rear sides of the movable bottom plate 32 and the movable pressing plate 34 .
[0025] In this embodiment, the movable base plate 32 and the movable pressing plate 34 are fixed by a plurality of fixing screws 35 and stabilizing nuts 36 , thereby increasing the stability between the movable base plate 32 and the movable pressing plate 34 .
[0026] Specifically, blocking blocks are provided on both the front and rear sides of the top of the movable bottom plate 32 and the bottom of the movable pressing plate 34 .
[0027] In this embodiment, the prestressed carbon fiber plate is positioned by a blocking block.
[0028] When in use, the connecting slot plate 41 is movably connected to the connecting block 4, and the hexagonal power connecting blocks 5 at both ends are connected to synchronous motors. The prestressed carbon fiber plate is respectively clamped in the movable bottom plate 32 and the fixed screw 35 at both ends, and the stabilizing nut 36 is rotated. The movable pressing plate 34 moves downward through the stabilizing nut 36 and the fixed screw 35. The movable pressing plate 34 drives the inclined block to move to the lower right side along the inclined slot 33. The movable pressing plate 34 moves downward and cooperates with the movable bottom plate 32 to press and fix the prestressed carbon fiber plate. Similarly, the fixing method of the prestressed carbon fiber plate at the other end After the prestressed carbon fiber plate is fixed by fixing the screw 35 and the stabilizing nut 36, the synchronous motors at both ends are started at the same time, and the synchronous motor drives the hexagonal power connecting block 5 to rotate, and the hexagonal power connecting block 5 drives the pulling threaded cylinder 43 to rotate, and the pulling threaded cylinder 43 pulls the fixed threaded rod 42 to move to the right through the threaded connection with the fixed threaded rod 42 during rotation, and the fixed threaded rod 42 pulls the upper and lower connecting blocks 4 to move synchronously to the right through the connecting card slot plate 41, and the upper and lower connecting blocks 4 drive the moving bottom plate 32 and the moving pressing plate 34 to move synchronously to the right, and the moving bottom plate 32 and the moving pressing plate 34 are moved synchronously to the right. The movable pressing plate 34 drives the inclined card block to move to the right side. Since the inclined card block moves to the lower right side along the inclined card slot 33, the inclined card slot 33 drives the movable pressing plate 34 to move to the lower right side. When the movable pressing plate 34 moves to the lower right side, it is restricted by the fixed screw 35 so that the movable pressing plate 34 always keeps moving horizontally to the lower right side. In the process that the movable bottom plate 32 and the movable pressing plate 34 move to the right side synchronously, the movable pressing plate 34 moves downward and cooperates with the movable bottom plate 32 to gradually increase the pressing force on the prestressed carbon fiber plate, so as to prevent the movable bottom plate 32 and the movable pressing plate 34 from pressing against the prestressed carbon fiber plate. During the tensioning process of the prestressed carbon fiber plate, the deformation force gradually increases, resulting in the situation that the pressing force of the movable base plate 32 and the movable pressing plate 34 is insufficient to cope with the gradually increasing deformation force of the prestressed carbon fiber plate, thereby improving the stability of the prestressed carbon fiber plate reinforcement equipment during tensioning of the prestressed carbon fiber plate. Similarly, the principle of gradual pressing of the prestressed carbon fiber plate is the same as above. After the tensioning is completed, the stabilizing nut 36 is turned again to fix the distance between the movable base plate 32 and the movable pressing plate 34, so that the prestressed carbon fiber plate can be fixed. At this time, the synchronous motor and the connecting slot plate 41 and other structures can be removed.
[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
