Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy engineering, specifically to a pre-embedded anchor sleeve structure for water conservancy engineering. Background Technology

[0002] Various structural components in water conservancy projects, such as dams, sluices, and dikes, require connection and fixation using steel bars or bolts. Anchor sleeves can tightly engage with these steel bars or bolts, providing high-strength anchoring force to ensure a firm and reliable connection between structural components, thereby improving the overall stability of the water conservancy project structure. Anchor sleeves are typically cylindrical structures made of metal, such as carbon steel, alloy steel, or stainless steel. Their inner walls are machined with threads that match the threads of the anchored steel bars or bolts, ensuring a tight fit and robust anchoring.

[0003] In hydraulic construction, the positioning and pouring of anchor sleeves are crucial steps to ensure structural stability and safety. Existing anchor sleeves on the market, due to their cylindrical structure, are prone to displacement during concrete pouring due to lateral pressure and vibration. This displacement can affect the insertion and connection accuracy of subsequent reinforcing bars, thus impacting the overall structural stability. Furthermore, the limited support capacity of cylindrical anchor sleeves can lead to uneven concrete coverage, resulting in voids or honeycomb-like defects around the sleeve. This weakens the bond between the sleeve and the concrete, reducing the anchoring effect. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-embedded anchor sleeve structure for water conservancy projects, so as to solve the problems mentioned in the background art, such as positional displacement and incomplete concrete wrapping, when the cylindrical anchor sleeves on the market are placed and fixed in a predetermined position.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded anchor sleeve structure for water conservancy projects, including a sleeve assembly made of metal, used for connection with external anchor components;

[0006] A support component is disposed outside the sleeve assembly and is used to support and limit the sleeve assembly. The support component is disposed at an equal angle outside the sleeve assembly, and the bottom of the support component is supported and fixed by a fixing component. The sleeve assembly includes a sleeve body and a tapered connector, and the tapered connector is integrally installed on the bottom of the sleeve body.

[0007] Preferably, the sleeve body has a threaded groove inside, and a protruding ring is provided at the connection position between the sleeve body and the tapered connector. The protruding ring is integrally installed on the outside of the sleeve body.

[0008] Preferably, the support assembly includes a sliding vertical rod, a connecting inclined rod, and a support rod, which are integrally installed together and arranged as a single unit from top to bottom.

[0009] Preferably, the support rod is arranged in an "L" shape, and a reserved hole is provided through the middle of both the support rod and the connecting inclined rod. The connecting inclined rod is inclined towards the position of the tapered connector.

[0010] Preferably, the inner side of the sliding vertical rod is provided with grooves at equal intervals, and the inner side of the grooves engages with the outer side of the protruding ring.

[0011] Preferably, the fixing component includes a fixing screw and a fastening nut. The fixing screw is disposed in a reserved hole in the middle of the support rod, and fastening nuts are disposed at the upper and lower positions of the fixing screw. The bottom of the fixing screw is provided with a tapered structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the water conservancy project uses a pre-embedded anchor sleeve structure;

[0013] 1. Equipped with support components, the anchor sleeve can be precisely fixed in the predetermined position, preventing displacement due to human error or external forces during concrete pouring. This helps ensure the accuracy of subsequent rebar insertion and connection, guaranteeing the connection quality between the rebar and the sleeve. Furthermore, during concrete pouring, the concrete generates significant lateral pressure. The evenly angled support components evenly distribute this lateral pressure, preventing deformation or displacement of the anchor sleeve due to lateral pressure and ensuring its stability during the pouring process.

[0014] 2. The tapered connector at the bottom of the sleeve body and the inclined rods on the entire support assembly are all inclined towards the central axis of the sleeve body. Therefore, they can guide the flow direction of the concrete, allowing the concrete to flow more smoothly around the sleeve, thereby reducing the accumulation and voids of concrete at the bottom of the sleeve. This ensures that the concrete can evenly wrap around the sleeve, helping to form a denser filling around the sleeve, reducing the generation of air bubbles and voids, thereby improving the density and strength of the concrete, enhancing the bond between the sleeve and the concrete, and ultimately improving the anchoring performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a pre-embedded anchor sleeve structure for water conservancy projects, including a sleeve assembly 1, which is made of metal and is used to connect with external anchor components;

[0022] Support component 2 is disposed outside sleeve assembly 1 and is used to support and limit the sleeve assembly 1. The support component 2 is disposed at equal angles outside sleeve assembly 1, and the bottom of the support component 2 is supported and fixed by fixing component 4. The sleeve assembly 1 includes sleeve body 11 and tapered connector 14. The tapered connector 14 is integrally installed at the bottom of sleeve body 11.

[0023] This application provides a pre-embedded anchoring sleeve structure for hydraulic engineering with a support component 2. Specifically, during use, firstly, a total station or theodolite is used for precise measurement to determine the installation position of the anchoring sleeve, and the center position of each anchoring sleeve is marked to ensure accurate positioning. The sleeve component 1 is then placed in the corresponding position. Afterward, the height of the support component 2 needs to be adjusted according to the required height. Once the height of the support component 2 is adjusted to the appropriate position, an external welding component is used to weld the support component 2 to the outer wall of the sleeve body 11, thus fixing the position of the support component 2 and the sleeve body 11. After the position is fixed, the sleeve body 11 and the bottom conical connector 14 are fixed to the ground using the fixing component 4 to prevent the sleeve component 1 from shifting. Finally, concrete is poured to complete the predetermined position fixing of the sleeve component 1. After fixing, it can be connected to the fixed anchor rod on the external bridge pier.

[0024] Specifically, according to Figure 1-2 As shown, the sleeve body 11 has a threaded slot 12 inside, and a protruding ring 13 is provided at the connection position between the sleeve body 11 and the tapered connector 14. The protruding ring 13 is integrally installed on the outside of the sleeve body 11. When the entire sleeve body 11 is connected to the external anchor rod, the external anchor rod needs to be inserted into the threaded slot 12 so that the anchor rod and the threaded part of the threaded slot 12 are tightly engaged, thus completing the anchor rod insertion work.

[0025] As a further preferred embodiment, according to Figure 2-4 As shown, the support assembly 2 includes a sliding vertical rod 21, a connecting inclined rod 22, and a support rod 23. The sliding vertical rod 21, the connecting inclined rod 22, and the support rod 23 are installed as a whole, and the three components are arranged as a whole from top to bottom.

[0026] The support rod 23 is arranged in an "L" shape. A reserved hole 3 is provided through the middle of both the support rod 23 and the connecting inclined rod 22. The connecting inclined rod 22 is inclined towards the position of the tapered connector 14.

[0027] The inner side of the sliding vertical rod 21 is provided with grooves 211 at equal intervals, and the inner side of the grooves 211 engages with the outer side of the protruding ring 13.

[0028] Specifically, during operation, when it is necessary to determine the position between the sliding vertical rod 21 and the sleeve assembly 1, it is necessary to control the groove 211 on the sliding vertical rod 21 to engage with the protruding ring 13. During engagement, by engaging with the groove 211 at different positions, the position of the equally spaced sliding vertical rod 21 can be determined to be at the same height. Finally, the sleeve body 11 and the sliding vertical rod 21 are welded together.

[0029] After welding, since the bottom of the sliding vertical rod 21 is connected to the “L”-shaped support rod 23 through the connecting inclined rod 22, the “L”-shaped support rod 23 can be used to fix the position of the sleeve assembly 1.

[0030] During subsequent concrete pouring, since the support rod 23 and the connecting inclined rod 22 are both provided with reserved holes 3 through the middle, and the connecting inclined rod 22 is set at the position of the tapered connector 14, the concrete can be guided, so that the concrete is guided to the surrounding area of ​​the sleeve assembly 1 from the outside of the support rod 23 and the connecting inclined rod 22 and the reserved hole 3, thereby achieving the purpose of full pouring.

[0031] Furthermore, according to Figure 2 As shown, the fixing component 4 includes a fixing screw 41 and a fastening nut 42. The fixing screw 41 is disposed in the reserved hole 3 in the middle of the support rod 23, and the fastening nut 42 is disposed at the upper and lower positions of the fixing screw 41. The bottom of the fixing screw 41 is provided with a tapered structure.

[0032] Specifically, during the fixing process, the tapered structure at the bottom of the fixing screw 41 can be directly inserted into the ground for fixing, ensuring that the concrete will not shift during the pouring process. At the same time, when it is necessary to make fine adjustments to the height of the entire sleeve assembly 1, the depth of the fixing screw 41 inserted into the ground can be controlled, thereby achieving precise positioning of the sleeve assembly 1. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
