Description

A type of buoyancy-resistant and corrosion-resistant anchor bolt Technical Field

[0001] This utility model relates to the field of anchor bolts, and in particular to an anchor bolt that is buoyant and corrosion resistant. Background Technology

[0002] An anchor is a tension member that penetrates deep into the strata. One end is connected to the engineering structure, and the other end is inserted into the strata to reinforce the rock and soil. An anchor mainly consists of a free section and an anchored section. The free section transmits the tension to the anchored area, and the anchored section transmits the tension to the depth of the soil, thereby enhancing the stability of the rock and soil.

[0003] Chinese Patent Publication No. CN209082488U discloses an anchor bolt, which includes a body with a cavity that is closed at the lower end and open at the upper end. The body is provided with several connecting plates along its height direction, and slots are provided on the body corresponding to the connecting plates for the insertion rod to move radially along the body. However, existing anchor bolts still have some shortcomings. Existing anchor bolts are usually galvanized for corrosion protection, but galvanizing the threaded front end of the anchor bolt is difficult and the quality is hard to guarantee. Moreover, during installation and use, the anchor bolt is prone to floating or loosening. Therefore, we propose an anti-floating and corrosion-resistant anchor bolt to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an anchor bolt that is buoyant and corrosion resistant, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-buoyancy and corrosion-resistant anchor bolt includes an anchor bolt body, a corrosion-resistant sleeve fitted on the outer surface of the anchor bolt body, a top plate fixedly connected to the outer surface of the anchor bolt body, the corrosion-resistant sleeve located above the top plate, an extension threaded rod at the top of the anchor bolt body, a first fastening nut threadedly connected to the outer surface of the extension threaded rod, the first fastening nut located at the top of the corrosion-resistant sleeve, an anti-buoyancy plate on the outer surface of the anchor bolt body located below the top plate, a bottom threaded rod at the bottom of the anchor bolt body, a second fastening nut threadedly connected to the outer surface of the bottom threaded rod, the second fastening nut located below the anti-buoyancy plate, and multiple guide holes formed on the upper surface of the anti-buoyancy plate.

[0007] In a further embodiment, the bottom end of the bottom threaded rod is threaded with a connecting nut, and the bottom surface of the connecting nut is fixedly connected with a bottom centering block.

[0008] In a further embodiment, the outer surface of the corrosion-resistant sleeve is provided with friction bumps, which are in contact with the poured cement.

[0009] In a further embodiment, an adhesive liquid is injected between the corrosion-resistant sleeve and the anchor bolt body, and the adhesive liquid is a corrosion-resistant coagulating material.

[0010] In a further embodiment, a connecting plate is threadedly connected to the outer surface of the extended threaded rod, and a third fastening nut is threadedly connected to the outer surface of the extended threaded rod, the third fastening nut being located above the connecting plate.

[0011] In a further embodiment, two threaded rods are installed on the upper surface of the connecting plate, and two reinforcing bolts are installed on the bottom surface of the connecting plate through reinforcing holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention relates to an anti-buoyancy and corrosion-resistant anchor bolt. A corrosion-resistant sleeve is fitted onto the outer surface of the anchor bolt body, and a special bonding liquid is injected between the two to ensure a tight fit between the sleeve and the anchor bolt. This effectively improves the corrosion resistance of the anchor bolt body. Furthermore, an anti-buoyancy plate installed at the bottom of the anchor bolt body allows the anchor bolt body to resist the weight of the plate during cement pouring, thus preventing the anchor bolt body from floating. Therefore, this device is more practical and effectively solves the problems existing in current devices. Attached Figure Description

[0022] Please refer to Figures 1-4. In this invention, an anti-buoyancy and corrosion-resistant anchor bolt includes an anchor bolt body 1. A corrosion-resistant sleeve 7 is fitted onto the outer surface of the anchor bolt body 1. A top plate 9 is fixedly connected to the outer surface of the anchor bolt body 1. The corrosion-resistant sleeve 7 is located above the top plate 9. An extension threaded rod 4 is provided at the top of the anchor bolt body 1. A first fastening nut 6 is threadedly connected to the outer surface of the extension threaded rod 4, located at the top of the corrosion-resistant sleeve 7. An anti-buoyancy plate 8 is provided on the outer surface of the anchor bolt body 1, located below the top plate 9. A bottom threaded rod 11 is provided at the bottom end of the anchor bolt body 1.

The upper surface of the anti-buoyancy plate 8 is provided with multiple guide holes 16. By sleeved with a corrosion-resistant sleeve 7 on the outer surface of the anchor body 1 and injecting a special adhesive liquid 18 between them, the tight fit between the corrosion-resistant sleeve 7 and the anchor can be ensured, thereby effectively improving the corrosion resistance of the anchor body 1. Furthermore, by installing the anti-buoyancy plate 8 at the bottom of the anchor body 1, the anchor body 1 can resist the gravity of the floating plate 8 by the cement when it is poured with cement, thereby preventing the anchor body 1 from floating.

[0023] The bottom threaded rod 11 is threaded with a connecting nut 12 at its bottom end. The bottom surface of the connecting nut 12 is fixedly connected with a bottom centering block 13. The outer surface of the corrosion-resistant sleeve 7 is provided with friction protrusions 17. The friction protrusions 17 are in contact with the poured cement. Through the provided friction protrusions 17, the device can be more firmly bonded to the cement.

[0024] A bonding fluid 18 is injected between the corrosion-resistant sleeve 7 and the anchor rod body 1. The bonding fluid 18 is a corrosion-resistant solidifying material. A connecting plate 5 is threadedly connected to the outer surface of the extension threaded rod 4. A third fastening nut 3 is threadedly connected to the outer surface of the extension threaded rod 4. The third fastening nut 3 is located above the connecting plate 5. Two connecting threaded rods 2 are installed on the upper surface of the connecting plate 5. Two reinforcing bolts 15 are installed on the bottom surface of the connecting plate 5 through the reinforcing hole 14, which increases the usability of the device and thus increases the practicality of the device.

[0025] The working principle of this utility model is as follows:

[0026] When using this anti-buoyancy and corrosion-resistant anchor, the workers first excavate the foundation pit. Then, the anti-buoyancy plate 8 in the anchor is inserted into the outer surface of the bottom threaded rod 11 and contacts the bottom surface of the top plate 9 in the device. The anti-buoyancy plate 8 is fixed by the second fastening nut 10, and the bottom centering block 13 is installed at the bottom end of the bottom threaded rod 11 by the connecting nut 12. Next, the workers apply adhesive liquid 18 to the outer surface of the anchor body 1 and put the corrosion-resistant sleeve 7 on the outer surface of the anchor body 1. The corrosion-resistant sleeve 7 is fixed by the first fastening nut 6 and the extension threaded rod 4 with the cooperation of the top plate 9. Then, the device is placed in the foundation pit, and the workers pour cement into the foundation pit. Finally, after the cement has solidified, the connecting plate 5 is installed by the third fastening nut 3 and the reinforcing bolt 15.
