Description

Technical Field

[0001] The utility model relates to the technical field of anchors, in particular to a carbon fiber plate anchor. Background Art

[0002] High-strength composite fiber materials such as carbon fiber boards are widely used in the reinforcement field of civil engineering projects. Usually, the carbon fiber boards are pasted on the surface of the reinforced components to improve the strength of the components. If the carbon fiber boards are tensioned and anchored to the surface of the components, the bending strength and crack resistance of the components can be improved. It can also improve the use efficiency of composite fiber materials and reduce reinforcement costs.

[0003] Carbon fiber plates can effectively solve the problems of difficult construction and large engineering workload of multi-layer carbon fiber cloth, and have good reinforcement effect. During the construction process, the carbon fiber plates are anchored by anchors. The prestressed reinforcement technology requires tensioning and anchoring of carbon fiber plates. Although carbon fiber plates have high tensile strength, they have poor shear resistance and are not easy to anchor. Some existing anchors achieve carbon fiber plate anchoring by bolt locking, which is prone to slippage and bolt loosening. The fixing effect is poor, and it is inconvenient to fix the moving rod. Its working reliability is poor. At the same time, during the tensioning of the carbon fiber plate, the installer needs to adjust the position of the bolts many times, which is troublesome to operate.

[0004] At the same time, some existing anchors use jacks to tension the carbon fiber board and use U-shaped plates to fix the jacks in position. However, the U-shaped plates of some anchors can only fix jacks of one diameter, and their applicability is low. When the jack diameter is small, the fixing height cannot be changed, which may cause the force application point of the jack and the carbon fiber board to be on different horizontal axes, which may affect the tensioning effect of the carbon fiber board and cause the reinforcement effect of the carbon fiber board to deteriorate.

The bottom of one side of the positioning block 4 is fixedly connected to a mounting block 7. The mounting block 7 is used to install parts. Limiting mechanisms 8 are arranged on both sides of the top of the mounting block 7. The position of the limiting mechanism 8 corresponds to the movable rod 5. The limiting mechanism 8 is used to limit the movable rod 5. When the parts on one side drive the movable rod 5 and the anchor block 2 to move to one side in an orderly and intermittent manner, the movable rod 5 is limited to prevent the movable rod 5 from moving in the opposite direction due to the pulling force, and at the same time increase The contact area with the moving rod 5 improves the fixing effect of the moving rod 5, improves the use effect, and is easy to operate. A positioning mechanism 9 is provided on one side of the mounting block 7. The positioning mechanism 9 is used to position the components of the limiting mechanism 8 to prevent the components of the limiting mechanism 8 from being displaced by external forces and affecting the fixing effect of the moving rod 5. A baffle 10 is rotatably connected to one side of the positioning block 4, and a rotating rod is fixedly connected to one side of the baffle 10 for easy use by installers. The baffle 10 is located below the positioning mechanism 9. The baffle 10 is used to block the components of the positioning mechanism 9 to prevent the components of the positioning mechanism 9 from being separated from the interior of the limiting mechanism 8 components. A U-shaped plate 11 is movably connected to one side of the top of the moving rod 5. The U-shaped plate 11 is located in the middle part of the fixed block 6 and the positioning block 4. The U-shaped plate 11 is used to support and fix the top parts to facilitate the use of internal parts. A moving mechanism 12 is set at the bottom of the U-shaped plate 11. The moving mechanism 12 is used to support the top parts. By adjusting the height, it can adapt to different diameters of parts to improve the use effect. A jack 13 is installed on the top of the U-shaped plate 11. The output shaft of the jack 13 is movably connected to one side of the positioning block 4, and one side of the jack 13 is movably connected to the fixed block 6. The jack 13 is used to push the moving rod 5 and the anchor block 2 to one side through the fixed block 6, and prestress the carbon fiber plate 3 to improve the reinforcement effect of the carbon fiber plate 3 on the concrete member.

A limiting groove 84 is provided on one side of the bottom of the moving rod 5. The number of the limiting grooves 84 is several and they are equidistantly distributed on one side of the bottom of the moving rod 5. The cross-section of the limiting groove 84 is triangular, which is consistent with the shape of the wedge-shaped part at the top of the limiting block 83. The inner wall of the limiting groove 84 is wedge-shaped with the top of the limiting block 83. Partially movable connection, through the wedge-shaped setting of the top of the limit block 83, when the jack 13 drives the moving rod 5 to move to one side, the limit block 83 slides along the bottom of the moving rod 5 inside the limit groove 84, and moves in an orderly manner according to the tensioning frequency of the jack 13. When the jack 13 stops tensioning, the top of the limit block 83 is embedded in the inside of the limit groove 84 and blocks each other with the limit groove 84, thereby fixing the moving rod 5, increasing the contact area with the moving rod 5, and improving the fixing effect of the moving rod 5, preventing the moving rod 5 from moving in the opposite direction with the tension of the carbon fiber plate 3, and improving the anchoring effect of the carbon fiber plate 3.

[0024] The positioning mechanism 9 includes a through hole 91 opened on the side of the limit block 83, and a positioning rod 92 is movably connected to the inner wall of the through hole 91.

They do not affect each other when in use. Positioning grooves 94 are opened at the left and right positions of one side of the positioning block 4. The positions of the positioning grooves 94 and the through hole 91 correspond to each other. One side of the positioning rod 92 is movably connected to the inner wall of the positioning groove 94. When the limit block 83 and the positioning groove 94 cooperate to fix the moving rod 5, the positioning rod 92 is made to correspond to the positions of the through holes 91 on both sides, and then the positioning rod 92 is inserted into the through hole 91 and the positioning groove 94.

The support plate 123 is arranged in an arc shape, and the support plate 123 is located above the bottom of the inner wall of the U-shaped plate 11. The bottom of the threaded rod 122 is fixedly connected to a stopper 124. The diameter of the stopper 124 is larger than the diameter of the threaded rod 122. When supporting the jack 13, the threaded sleeve 121 is rotated to control the threaded rod 122 to drive the support plate 123 to move to support the jack 13. The jack 13 can be adjusted according to jacks 13 of different diameters, thereby improving applicability and simplifying operation. At the same time, the threaded sleeve 121 is blocked by the stopper 124 to prevent the threaded rod 122 from escaping from the inside of the threaded sleeve 121, thereby improving the use effect.

[0026] Working principle: First, anchor the two ends of the carbon fiber plate 3 through the limit frame 1 and the anchor block 2, then rotate the threaded sleeve 121 to control the threaded rod 122 to drive the support plate 123 to move to support the jack 13, which can be flexibly adjusted according to the diameter of the jack 13, and then install the jack 13. After installation, the carbon fiber plate 3 can be prestressed by the jack 13, and the fixed block 6 is controlled to drive the moving rod 5 and the anchor block 2 to move intermittently to one side, and the carbon fiber plate 3 is tightened by applying force on both sides at the same time, and the carbon fiber plate 3 is lifted. The reinforcing effect is achieved by intermittently moving the moving rod 5 at a frequency, and the limiting groove 84 moves in sequence on the top of the limiting block 83. When the prestressing of the carbon fiber plate 3 is completed, the limiting block 83 is embedded in the limiting groove 84 on its top. Then the installer inserts the positioning rod 92 into the through hole 91 and the positioning groove 94 to position the limiting block 83, and then blocks the connecting plate 93 through the baffle 10 to enhance the fixing effect of the moving rod 5. Then the excess part of the moving rod 5 is cut off and the jack 13 and the fixing block 6 are removed.
