[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0029] Example 1: A joint structure for an anchor bolt tension gauge and a fiberglass anchor bolt, specifically as follows: Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the device includes a pull head 10, which is cylindrical; a connecting structure comprising a first connecting part and a second connecting part. The first connecting part includes a connecting rod 13 disposed outside the pull head 10, with a first threaded rod 14 fixedly installed at one end of the connecting rod 13. A first threaded groove 11 is formed inside the pull head 10, and the connecting rod 13 is spirally installed inside the first threaded groove 11. A protective ring plate 12 is fixedly installed on one outer wall of the pull head 10. The second connecting part includes a conical sleeve 16 fixedly installed at the other end of the connecting rod 13, with a second threaded groove 17 formed inside the conical sleeve 16. Sixteen sets of arc-shaped plastic plates 18 are fixedly installed inside the conical sleeve 16. The anchor bolt tension gauge is connected and fixed to the fiberglass anchor bolt through the connecting structure. By rotating the connecting rod 13, the connecting rod 13 is spirally installed inside the first threaded groove 11, and the protective ring plate 12 wraps around the outer wall of the first threaded rod 14. The fiberglass anchor rod is installed through the second threaded groove 17, and the fiberglass anchor rod is assisted in limiting its position through the arc-shaped plastic plate 18.
[0030] Specifically, such as Figure 3 and Figure 4As shown, the first connecting part also includes a protective ring plate 12 fixedly installed at one end of the pull head 10. One end of the protective ring plate 12 is tightly attached to one end of the connecting rod 13, and an anti-slip strip 15 is fixedly installed on the outer wall of the connecting rod 13. By holding the anti-slip strip 15 and rotating the connecting rod 13, the force inside the tapered sleeve 16 is distributed through the tapered shape of the tapered sleeve 16, reducing the pressure at the joint.
[0031] Based on the above, the structure of the pull head 10, the first threaded groove 11, the protective ring plate 12, the connecting rod 13, the first threaded rod 14, the anti-slip ring strip 15, the conical sleeve 16, the second threaded groove 17, and the arc-shaped plastic plate 18 achieves the purpose of connecting and fixing the anchor bolt tension gauge and the fiberglass anchor bolt, improving the fixing effect at the joint, dispersing the pressure at the joint, reducing the pressure on the joint, extending the service life of the device, and improving the durability of the device.
[0032] Example 2: Based on Example 1, specifically as follows... Figure 1 and Figure 3 As shown, a pull rod 23 is provided on the outside of the pull head 10, and a pressure cylinder 24 is slidably installed inside the pull rod 23. One end of the pressure cylinder 24 is fixedly connected to the other end of the pull head 10. The pressure cylinder 24 moves inside the pull rod 23, pushing the pull head 10 to move, and thus pushing the fiberglass anchor rod to move.
[0033] Specifically, such as Figure 1 and Figure 3 As shown, a high-pressure oil pipe 25 is fixedly installed inside the tie rod 23, and one end of the high-pressure oil pipe 25 is fixedly connected to an external anchor bolt tension gauge. The tie rod 23 is connected to the anchor bolt tension gauge through the high-pressure oil pipe 25.
[0034] Specifically, such as Figure 4 As shown, the outer wall of the anti-slip ring 15 is coated with an anti-slip paint, which improves the gripping effect of the anti-slip ring 15.
[0035] Specifically, such as Figure 6 As shown, a set of arc-shaped limiting grooves 19 are formed between the two sets of arc-shaped plastic plates 18, for a total of twelve sets of arc-shaped limiting grooves 19. This facilitates the spiral installation of the fiberglass anchor rod inside the conical sleeve 16.
[0036] Based on the above, the structure of pull head 10, anti-slip ring 15, arc-shaped plastic plate 18, arc-shaped limiting groove 19, pull rod 23, pressure cylinder 24 and high-pressure oil pipe 25 achieves the purpose of pushing the fiberglass anchor rod, enabling the fiberglass anchor rod to be installed quickly, simplifying the operation steps of the device, and improving the flexibility of the device.
[0037] Example 3: Based on Examples 1 and 2, specifically as follows... Figure 1 and Figure 2As shown, a fiberglass anchor bolt includes the anchor bolt tension gauge connector structure described in any of the above-mentioned embodiments and a fiberglass anchor bolt 20. A tray nut 21 is spirally installed on the outer wall of the fiberglass anchor bolt 20. A third threaded groove 22 is formed on the inner wall of the tray nut 21. One end of the fiberglass anchor bolt 20 is spirally installed inside the second threaded groove 17. An arc-shaped plastic plate 18 is snapped into the threaded groove of the fiberglass anchor bolt 20. The fiberglass anchor bolt 20 is spirally installed inside the third threaded groove 22, and the position of the tray nut 21 on the third threaded groove 22 is adjusted to perform fiberglass anchor bolt installation and tension testing.
[0038] In summary, the structure of the fiberglass anchor rod 20, the tray nut 21, and the third threaded groove 22 achieves the purpose of installing and fixing the fiberglass anchor rod and conducting tensile tests, thereby detecting the fixing effect and support strength of the fiberglass anchor rod and optimizing the user experience of the device.
[0039] Working principle: The pull head 10 is cylindrical with a first threaded groove 11 inside and a connecting rod 13 on the outside. One end of the connecting rod 13 is fixedly installed with a first threaded rod 14. Rotating the connecting rod 13 causes the first threaded rod 14 to be screwed into the first threaded groove 11, thus connecting and fixing the connecting rod 13 to the pull head 10. A protective ring plate 12 is fixedly installed on one side of the outer wall of the pull head 10. One end of the protective ring plate 12 is tightly attached to one end of the connecting rod 13, wrapping and protecting the outer wall of the first threaded rod 14 to prevent damage or interference with the surrounding environment. An anti-slip strip 15 is fixedly installed on the outer wall of the connecting rod 13, and the outer wall of the anti-slip strip 15 is coated with anti-slip paint. When the construction personnel hold the anti-slip strip 15 to rotate the connecting rod 13, the grip is improved, making the rotation operation more stable and effortless. A conical sleeve 16 is fixedly installed on the other end of the connecting rod 13. A second threaded groove 17 is opened inside the conical sleeve 16 for installing fiberglass anchor rods. One end of the fiberglass anchor rod 20 can be spirally installed into the second threaded groove 17 to achieve a preliminary connection. Sixteen sets of arc-shaped plastic plates 18 are fixedly installed inside the conical sleeve 16. An arc-shaped limiting groove 19 is formed between two sets of arc-shaped plastic plates 18, for a total of twelve sets of arc-shaped limiting grooves 19. When the fiberglass anchor rod 20 is spirally installed inside the conical sleeve 16, the arc-shaped plastic plates 18 are snapped into the threaded grooves of the fiberglass anchor rod 20, which plays an auxiliary limiting role for the fiberglass anchor rod 20 and enhances the connection stability. At the same time, the conical shape of the conical sleeve 16 can disperse the internal force, reduce the pressure at the joint, and avoid loosening or damage to the connection due to force concentration. A pull rod 23 is set on the outside of the pull head 10, and a pressure cylinder 24 is slidably installed inside the pull rod 23. One end of the pressure cylinder 24 is fixedly connected to the other end of the pull head 10. During the tensile test, the pressure cylinder 24 moves inside the pull rod 23, pushing the pull head 10 to move, which in turn drives the fiberglass anchor rod connected to the pull head 10 via a connecting structure. A high-pressure oil pipe 25 is fixedly installed inside the pull rod 23, with one end of the high-pressure oil pipe 25 fixedly connected to an external anchor rod tension gauge. The pull rod 23 is connected to the anchor rod tension gauge via the high-pressure oil pipe 25, and the anchor rod tension gauge provides power to the pressure cylinder 24 through the high-pressure oil pipe 25, causing the pressure cylinder 24 to generate corresponding thrust or pull force, thereby achieving the tensile test of the fiberglass anchor rod. A tray nut 21 is spirally installed on the outer wall of the fiberglass anchor rod 20, and a third threaded groove 22 is formed on the inner wall of the tray nut 21. The fiberglass anchor rod 20 is spirally installed in the third threaded groove 22. By adjusting the position of the tray nut 21 on the third threaded groove 22, the installation requirements of the fiberglass anchor rod in different engineering scenarios can be met, and it plays a role in stabilizing and fixing the fiberglass anchor rod during the tensile test.
