[0001] The utility model relates to the technical field of carbon plate construction, in particular to an anti-drop anchor type prestressed carbon plate construction reinforcement tool. Background Art

[0002] Prestressed carbon fiber plate is a reinforcement structure that improves the strength and self-stabilization ability of building and bridge structural systems. It has the advantages of convenient construction and simple operation. It can restrain the generation and development of cracks in existing buildings and bridge components, improve their bearing capacity and service life, and has been widely used in bridges, buildings and other projects. The two ends of the prestressed carbon plate are installed on the back of the bridge through anchor supports. However, the existing prestressed carbon plate anchor supports need to be anchored with chemical anchor bolts after drilling holes at the bottom of the beam. During the installation of the prestressed carbon fiber plate, the anchor device mostly uses wedge-shaped clamping pieces and adhesive to fix the carbon fiber plate. This fixing method is more troublesome during installation and has limited anchoring strength. For this reason, we propose an anti-drop anchor prestressed carbon plate construction reinforcement tool. Utility Model Content

[0017] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0018] like Figure 1-3 As shown, the utility model is an anti-anchoring prestressed carbon plate construction reinforcement tool, including a bridge 1, a mounting block 11 is fixedly provided on one side of the bridge 1, a jack 12 is fixedly installed in the mounting block 11, the jack 12 is installed in the mounting block 11, the jack 12 is externally connected to an output device, and the jack 12 can be retracted inwardly through the output device, and a carbon plate 13 is clamped at the output end of the jack 12, and the jack 12 can pull one side of the carbon plate 13 inward, so that the carbon plate 13 can fit to the bottom of the bridge 1.

[0019] A fixed anchor rod 22 is provided in the other side of the bridge 1, and the bottom end of the fixed anchor rod 22 passes through the top of the connected fixing plate 2, and the lower end of the fixed anchor rod 22 is threadedly connected to the fastening nut 23. By rotating the fastening nut 23, the fastening nut 23 and the fixed anchor rod 22 are threadedly connected. The rotation of the fastening nut 23 can fix the fixing plate 2 in the groove opened in the bridge 1, and the reinforcement device on the other side of the carbon plate 13 can be conveniently installed at the lower end of the bridge 1.

[0020] An upper cover plate 24 and a lower cover plate 25 are movably provided in the fixed plate 2, an upper clamp 3 is provided on the lower side of the upper cover plate 24, a lower clamp 31 is provided above the lower cover plate 25, the upper cover plate 24 and the lower cover plate 25 are fixed by fixing bolts 26, when the carbon plate 13 passes through the upper cover plate 24 and the lower cover plate 25, by rotating the fixing bolts 26, the fixing bolts 26 can push the upper cover plate 24 and the lower cover plate 25 to move inward, and can clamp and fix the carbon plate 13 placed in the upper cover plate 24 and the lower cover plate 25.

[0021] The carbon plate 13 is fixedly clamped inside the upper clamp 3 and the lower clamp 31. The upper clamp 3 and the lower clamp 31 are inclined, and the inclination angle of the inclined surfaces of the upper clamp 3 and the lower clamp 31 is 2°. The upper clamp 3 and the lower clamp 31 can be anchored on site by screwing in the fixing bolts 26. A wedge structure is designed in the clamp structure to achieve wedge-shaped cooperation between the upper and lower clamps and the upper and lower cover plates, thereby improving the anchoring efficiency coefficient. The set inclination angle can further ensure the stability of the carbon plate during the processing and prevent the carbon plate 13 from detaching from the fixing plate 2.
