Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of anchor bolt, specifically is a kind of stability anchor bolt structure. BACKGROUND

[0002] In many engineering fields, such as building, bridge, port, etc., anchor bolt structure plays a crucial role as an important connecting and fixing device. It needs to firmly connect various structural components together to withstand various external forces, ensuring the stability and safety of the entire engineering structure.

[0003] Traditional anchor bolt structure usually has some shortcomings. On the one hand, during the pre-buried installation process, the connection stability between the pre-buried plate and the anchor bolt body is not ideal. As a key component for connecting the anchor bolt and the foundation structure, if the connection between the pre-buried plate and the anchor bolt body is not stable enough, it is easy to cause problems such as loosening and displacement during subsequent construction and use, thereby affecting the bearing capacity and stability of the entire anchor bolt structure. On the other hand, for the chain and other components that pass around the top of the anchor bolt, there is a lack of effective swing amplitude limiting measures. When the chain is subjected to external force, it may produce excessive swing, not only causing impact and damage to the anchor bolt structure itself, but also affecting the normal work of other structural components connected thereto, reducing the safety and reliability of the entire engineering structure.

[0004] In addition, in some special use scenarios, such as the need to frequently adjust the position of the chain or have different requirements for the swing amplitude of the chain, the traditional anchor bolt structure often fails to meet these needs, lacking flexibility and adjustability. SUMMARY

[0005] The purpose of the utility model is to provide a stability anchor bolt structure to solve the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a stability anchor bolt structure, comprising an anchor bolt body, both ends of the anchor bolt body are fixed with a screw rod, a pre-buried plate is sleeved on the rod body of the screw rod, a sleeve ring is sleeved on the rod body of the anchor bolt body, a cross beam is fixed on the surface of the sleeve ring, and a hand screw is screwed on the surface of the sleeve ring, the hand screw penetrates through the sleeve ring and clamps the anchor bolt body.

[0007] Preferably, the anchor bolt body is a "U"-shaped round rod, the end surface diameter of the anchor bolt body is greater than the rod diameter of the screw rod, the pre-buried plate is a square plate structure, a round opening is formed on the surface of the pre-buried plate, and the round opening is sleeved on the screw rod.

[0008] Preferably, a compression ring is fixedly sleeved on both ends of the anchor bolt body, the compression ring is a circular truncated cone ring plate structure, and the bottom end of the compression ring is coplanar with the end surface of the anchor bolt body.

[0009] Preferably, a nut is screwed onto the rod body of the screw, and the nut clamps the embedded plate below the pressure ring.

[0010] Preferably, there are two collars, which are respectively fitted onto two parallel rods of the anchor bolt body, and the crossbeam is fixed between the two collars.

[0011] Preferably, a rubber sleeve is fitted and fixed on each of the two parallel rods of the anchor bolt body. The rubber sleeve is clamped between the collar and the rod of the anchor bolt body. A screw hole is opened on the surface of the collar, and a hand-tightening screw passes through and is screwed into the screw hole.

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

[0013] The robust anchor bolt structure proposed in this invention forms a reliable connection structure by fitting the circular opening of the embedded plate onto the bolt body and clamping the embedded plate under the pressure ring using a nut. The frustum-shaped ring plate structure of the pressure ring has its bottom end coplanar with the end circular surface of the anchor bolt body, allowing for better fit with the embedded plate, increasing the contact area, and improving the connection stability between the embedded plate and the anchor bolt body. During the pre-embedding and grouting reinforcement process, this connection method effectively prevents problems such as loosening and displacement of the embedded plate, ensuring the quality of the anchor bolt installation.

[0014] The required chain swing amplitude may vary depending on the application scenario. This anchor bolt structure, by adjusting the height of the crossbeam, can flexibly adapt to different needs, meeting the limitations on chain swing amplitude in various engineering projects, thus improving the versatility and adaptability of the anchor bolt structure.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a stable anchor bolt structure, including an anchor bolt body 1, with screw rods 2 fixed at both ends of the anchor bolt body 1, and a pre-embedded plate 3 sleeved on the shank of the screw rod 2. The anchor bolt body 1 is a U-shaped round rod, and the diameter of the end circular surface of the anchor bolt body 1 is larger than the diameter of the screw rod 2. The pre-embedded plate 3 is a square plate structure, and a circular opening is opened on the surface of the pre-embedded plate 3, which is sleeved on the screw rod 2. A pressure ring 4 is fixed at both ends of the anchor bolt body 1. The pressure ring 4 is a frustum-shaped ring plate structure, and the bottom end of the pressure ring 4 is coplanar with the end circular surface of the anchor bolt body 1. A nut 10 is screwed onto the shank of the screw rod 2, and the nut 10 clamps the pre-embedded plate 3 below the pressure ring 4.

[0024] In use, the round opening on the surface of the embedded plate 3 is fitted onto the body of the screw rod 2, and then the nut 10 is screwed onto the body of the screw rod 2. After the nut 10 and the screw rod 2 are screwed and locked, the embedded plate 3 is clamped between the nut 10 and the pressure ring 4, and the embedded plate 3 and the screw rod 2 are embedded in the ground and reinforced with grout. The top of the anchor bolt body 1 is used to bind the chain.

[0025] A collar 6 is fitted onto the rod of the anchor bolt body 1. A crossbeam 9 is fixed to the surface of the collar 6, and a hand-tightening screw 8 is screwed onto the surface of the collar 6. The hand-tightening screw 8 passes through the collar 6 and clamps the anchor bolt body 1. There are two collars 6, which are respectively fitted onto two parallel rods of the anchor bolt body 1. The crossbeam 9 is fixed between the two collars 6. A rubber sleeve 5 is fitted and fixed onto each of the two parallel rods of the anchor bolt body 1. The rubber sleeve 5 is clamped between the collar 6 and the rod of the anchor bolt body 1. A screw hole 7 is opened on the surface of the collar 6, and the hand-tightening screw 8 passes through and is screwed into the screw hole 7.

[0026] In use, before the bottom end of the anchor bolt body 1 is buried underground, the collar 6 is placed on the rod of the anchor bolt body 1, and the hand screw 8 is tightened to clamp the rubber sleeve 5 to brake the collar 6. After the bottom end of the anchor bolt body 1 is buried underground, when the chain passes over the top of the anchor bolt body 1, the swing amplitude of the chain after passing through the anchor bolt body 1 can be limited by adjusting the height of the crossbeam 9.

[0027] Detailed instructions for using the stable anchor bolt structure: Place the round opening on the surface of the embedded plate 3 onto the shaft of the screw rod 2, ensuring the position of the embedded plate 3 meets design requirements. Select the nut 10 that matches the screw rod 2 and screw it onto the shaft of the screw rod 2. Continuously tighten the nut 10, gradually locking it to the screw rod 2. During this process, the embedded plate 3 will be clamped between the nut 10 and the pressure ring 4 until a suitable preload is achieved. Place the anchor bolt structure with the embedded plate 3 and screw rod 2 in the predetermined underground location, ensuring the position and orientation of the anchor bolt body 1 are correct. Perform grouting reinforcement work, selecting appropriate grouting materials and processes according to relevant construction specifications and requirements, ensuring the grouting is dense and tightly bonded to the surrounding soil, enhancing its stability. Before embedding the bottom end of the anchor bolt body 1 underground, place the collar 6 onto the shaft of the anchor bolt body 1. Since the anchor bolt body 1 is a U-shaped round rod with two parallel rods, collars 6 are fitted onto each rod. The hand-tightening screw 8 is tightened until it passes through the screw hole 7 on the collar 6, clamping it onto the rubber sleeve 5. Tightening the hand-tightening screw 8 brakes the collar 6, fixing it in a suitable position on the rod of the anchor bolt body 1. After the bottom end of the anchor bolt body 1 is buried underground and grouting reinforcement is completed, the chain is wrapped around the top of the anchor bolt body 1 and secured according to actual usage requirements. Depending on the chain's usage scenario and requirements, the swing amplitude of the chain after passing through the anchor bolt body 1 is limited by adjusting the height of the crossbeam 9. The specific adjustment method is as follows: loosen the hand-tightening screw 8 to release the brake on the collar 6, allowing the collar 6 to move on the rod of the anchor bolt body 1, causing the crossbeam 9 to move up and down to a suitable position. Then tighten the hand-tightening screw 8 to re-secure the collar 6, thereby limiting the chain's swing amplitude.
