[0002] In the field of building structures, the beam-column joint area, as the connection between beams and columns, is a key component for bearing and transmitting loads. Carbon fiber cloth beam-column reinforcement is a technical means of strengthening beams and columns in building structures by utilizing the high strength characteristics of carbon fiber cloth. The carbon fiber cloth is bonded to the surface of the beam and column with an adhesive, so that it can work together with the original structure to bear the load, thereby improving the load-bearing capacity and seismic performance of the beam and column.
[0003] When using carbon fiber as a beam and column reinforcement material, it is difficult to effectively constrain the carbon fiber cloth located at the inside corner of the beam and column, which may lead to a decrease in the bonding and adhesion of the carbon fiber cloth, thereby affecting the reinforcement effect of the beam and column structure. Therefore, it is necessary to provide a multi-directional carbon fiber cloth cross-anchoring reinforcement structure for building beam and column joints. The structure adopts a cross-wrapping positioning structure to fix the structure used to press the carbon fiber cloth, and at the same time, it adopts a pressing structure adapted to the inside corner angle to ensure good adhesion between the carbon fiber cloth and the beam and column surface.

[0021] In the following description, embodiments of the multi-directional carbon fiber cloth cross-anchoring reinforcement structure for building beam-column joints of this utility model will be described with reference to the accompanying drawings.
[0022] Figure 1-4 This invention illustrates a multi-directional carbon fiber cloth cross-anchoring reinforcement structure for building beam-column joints, comprising four clamps 1 arranged in a ring on the column surface and multiple U-shaped fiber cloths 2 bonded to the beam surface. Two edge-pressing fiber cloths 3 are provided on the surface of the U-shaped fiber cloths 2. Threaded pins 6 are welded to both sides of the top of the clamps 1. An arc-shaped groove 7, adapted to the threaded pins 6, is opened at the bottom of the angle steel 4. The threaded pins 6 are inserted into the inner cavity of the arc-shaped groove 7. A nut 8 is threaded onto the surface of the threaded pins 6 and presses into the bottom of the inner cavity of the angle steel 4. Through the coordinated use of the threaded pins 6, the arc-shaped groove 7, and the nut 8, the position and position of the angle steel 4 can be adjusted, allowing the angle steel 4 to be accurately pressed into the inner corner of the beam-column joint, thus pressing and fixing the U-shaped fiber cloths 2 and the edge-pressing fiber cloths 3. A rubber gasket 9 is bonded to the inner wall of the clamps 1. The clamping fiber cloth 3 is pressed onto the surface of the U-shaped fiber cloth 2 in close contact with the column surface. Angle steel 4 is provided on both sides of the top of the clamping seat 1. The angle steel 4 is pressed onto the surface of the clamping fiber cloth 3 and located at the inside corner of the beam and column. An anchoring component 5 is provided on the surface of the clamping seat 1. The anchoring component 5 includes a circular groove 51 opened on the surface of the clamping seat 1. A threaded anchor rod 52 is rotatably connected to the inner cavity of the circular groove 51. A threaded hole 53 adapted to the threaded anchor rod 52 is opened on one side of the clamping seat 1. Threaded tubes 54 are welded on both sides of the clamping seat 1. The threaded tubes 54 are threadedly connected to the surface of the threaded anchor rod 52. The setting of the threaded tubes 54 guides the threaded anchor rod 52 and increases the threaded connection area between the clamping seat 1 and the threaded anchor rod 52, thereby improving the connection stability between the threaded anchor rod 52 and the clamping seat 1, and providing a longer threaded connection stroke for the threaded anchor rod 52.
[0023] Working principle: When using this utility model, the user attaches U-shaped fiber cloth 2 to the surface of the beam, with multiple U-shaped fiber cloths 2 evenly distributed. Then, the user attaches edge-pressing fiber cloth 3 to the top and middle of the U-shaped fiber cloth 2 to press and fix the U-shaped fiber cloth 2, thereby enhancing the strength of the beam. The user then clamps the four clamps 1 at the four external corners of the column. Then, the user rotates the threaded anchor rod 52 so that the threaded anchor rod 52 enters the inner cavity of the threaded hole 53 opened on the surface of the adjacent clamp 1, and rotates and tightens all four threaded anchor rods 52, so that the four clamps 1 are stably clamped at the external corners of the column. The user then adjusts the position of the angle steel 4 and presses the angle steel 4 at the internal corner of the beam and column, which also presses the U-shaped fiber cloth 2 and edge-pressing fiber cloth 3 at the internal corner. Finally, the user rotates the nut 8 to the surface of the threaded pin 6 and tightens it to press and fix the position of the angle steel 4.
[0024] In summary, this multi-directional carbon fiber cloth cross-anchoring reinforcement structure for beam-column joints strengthens beams and columns by bonding U-shaped fiber cloth 2 and edge-pressing fiber cloth 3. The angle steel 4 is installed in place by using clamp 1 and anchoring components 5 in conjunction with the angle steel 4 to press and anchor the U-shaped fiber cloth 2 and edge-pressing fiber cloth 3 located at the inside corner of the beam-column joint. This achieves accurate installation and simultaneous multi-directional anchoring.
