[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, a steel structure anchor reinforcement installation structure includes a positioning plate 1 and an anchor rod 2 with bolts 21, and also includes a clamp sleeve 3 slidably sleeved on the anchor rod 2. The clamp sleeve 3 is provided with an elastic pressure plate 33 arranged in a circle and maintaining a predetermined angle with the vertical plane.

[0028] It also includes a fastening sleeve 4 with a retaining sleeve 42, and the retaining sleeve 42 slides and abuts against the elastic pressure plate 33, so that multiple elastic pressure plates 33 are attached to the anchor rod 2 and the bolt 21.

[0029] Specifically, the fastening sleeve 4 is located outside the clamp sleeve 3, and multiple elastic pressure plates 33 form an inverted platform shape, while the retaining sleeve 42 has an inverted platform-shaped inner wall that abuts against the outer wall of the elastic pressure plate 33.

[0030] Furthermore, the retaining sleeve 42 is part of the fastening sleeve 4, and the length of the fastening sleeve 4 is greater than the length of the steel structure foot that needs to be exposed, so that the fastening sleeve 4 can provide efficient protection for the steel structure foot.

[0031] As the retaining sleeve 42 gradually slides towards the end of the elastic pressure plate 33, the frustum-shaped surface of the inner wall of the retaining sleeve 42 abuts against the ends of multiple elastic pressure plates 33 and closes them together. This clamps and compacts the side wall of the anchor rod 2, the side wall of the bolt 21, or the side wall at the connection between the two, thereby shielding and protecting the connection position of the bolt 21. At the same time, it also plays an additional connecting role, resisting the torsion and stress on the bolt 21, thus achieving the purpose of reinforcing the steel structure anchor and ensuring the stability and safety of the steel structure column during installation.

[0032] As a further embodiment of this utility model, the clamp sleeve 3 is also provided with a threaded sliding sleeve 31, and the fastening sleeve 4 is provided with a rotating sleeve 41 that is threadedly connected to the threaded sliding sleeve 31.

[0033] Specifically, the threaded sleeve 31 is part of the clamp sleeve 3, and the thread is formed on the outer wall of the threaded sleeve 31.

[0034] Furthermore, the rotating sleeve 41 is the lower part of the fastening sleeve 4 and is connected to the abutting sleeve 42.

[0035] The rotating sleeve 41 moves on the threaded sliding sleeve 31 by rotating, so that the retaining sleeve 42 is driven by the rotating sleeve 41 to move in a spiral motion, thereby causing the closing action to occur.

[0036] As another embodiment further provided in this utility model, the fastening sleeve 4 is also provided with a protective sleeve 43 located on the outside of the anchor rod 2.

[0037] Specifically, the protective sleeve 43 is connected to the upper end of the retaining sleeve 42.

[0038] The inner wall of the protective sleeve 43 covers the outside of the steel structure footing, providing shielding protection for the steel structure itself and the bolts 21, greatly reducing the impact of external corrosion.

[0039] As another embodiment further provided by this utility model, the protective sleeve 43 is provided with an elastic end 44 that abuts against the end face of the positioning plate 1.

[0040] Specifically, the elastic ends 44 are arranged in a circular pattern, and a rubber membrane is fixedly installed between adjacent elastic ends 44 to provide a shielding and sealing effect on the elastic ends 44.

[0041] The end of the elastic end 44 abuts against the positioning plate 1, so that the positioning plate 1 applies pressure to the elastic end 44 when it is installed and fixed, so that the fastening sleeve 4 can fit against the lower end face of the positioning plate 1 for installation, and further strengthens the shielding and protection of the bolt 21 when the elastic end 44 is deformed under pressure.

[0042] As another embodiment of this utility model, a plurality of sliders 32 are fixedly installed in the threaded sleeve 31, and the foot rod 2 is provided with a groove 22 for the sliders 32 to slide.

[0043] By assembling the slider 32 and the groove 22, the clamp sleeve 3 can be moved vertically to a predetermined position. When the slider 32 comes into contact with one end of the groove 22, the threaded sleeve 31 directly blocks the connection between the bolt 21 and the anchor rod 2, which can play a basic protection function when transporting the steel structure anchor.

[0044] As another embodiment provided by this utility model, the angle between the elastic pressure plate 33 and the anchor rod 2 is 8° in the default state.

[0045] The included angle becomes zero after the elastic pressure plate 33 is deformed by pressure, so that there is no vertical gap after the elastic pressure plate 33 is closed, and the purpose is to extend the basic protection area of ​​the threaded sleeve 31.

[0046] As another embodiment provided in this utility model, the outer wall of the fastening sleeve 4 is provided with a plurality of grooves.

[0047] Specifically, such as Figure 3As shown by the vertical line, the groove at the lower end of the fastening sleeve 4 is arranged in a circular pattern. This groove can also be a plane, so that the outer wall of the lower end of the fastening sleeve 4 is polygonal.

[0048] Multiple grooves are used to increase the resistance when the fastening sleeve 4 is rotated, so as to avoid slippage during the rotation of the fastening sleeve 4.

[0049] As another embodiment further provided in this utility model, the elastic pressure plate 33 is specifically an elastic metal strip.

[0050] Specifically, a rubber pad is fixedly installed on the inner wall of the elastic pressure plate 33, and the thickness of the rubber pad is negligible.

[0051] The elastic metal strip makes the elastic pressure plate 33 deform significantly under pressure, that is, the included angle gradually disappears, while ensuring the clamping effect and anti-slip sealing effect of the steel structure foot.

[0052] As another embodiment further provided in this utility model, the protective sleeve 43 is specifically a steel sleeve.

[0053] The steel protective sleeve 43 makes it resistant to pressure and impact, increasing the protection effect on the internal steel structure feet.

[0054] As another embodiment further provided in this utility model, the elastic end 44 is specifically a V-shaped elastic metal plate.

[0055] After being pressed by the elastic end 44, one side of the V-shape is attached to the lower end face of the positioning plate 1 to increase the contact surface of the positioning plate 1. At the same time, it can also extend the sealing contact surface of the rubber membrane and improve the protection effect on the steel structure foot.

[0056] Working principle: The retaining sleeve 42 gradually slides towards the end of the elastic pressure plate 33, so that the inner wall of the retaining sleeve 42 abuts against the ends of multiple elastic pressure plates 33 and closes together, clamping and compacting the side wall of the anchor rod 2, the side wall of the bolt 21, or the side wall at the connection between the two, thereby achieving shielding and protection of the bolt 21 connection position, and also playing an additional connection function to resist the torque and stress on the bolt 21, thus achieving the purpose of reinforcing the steel structure anchor.

[0057] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
