Description

Technical Field

[0001] This utility model relates to the field of chemical anchor technology, and in particular to a chemical anchor that prevents detachment. Background Technology

[0002] Chemical anchors are high-strength anchors made primarily of vinyl resin, formerly known as chemical plugs. They are a new type of anchor that emerged after expansion anchors. They are composite components that use a special chemical adhesive to bond the threaded rod to a drilled hole in a concrete substrate, thus achieving anchoring of the fastener. During the insertion of chemical anchors into pre-embedded holes, the gaskets worn on the outside of the threaded rod are movable, making it difficult to limit their movement and affecting the stability of the threaded rod insertion process. Furthermore, the smooth bottom of the gasket, after contact with the wall, results in low friction and is prone to loosening, leading to displacement and detachment of the threaded rod. Therefore, we have proposed a chemical anchor designed to prevent detachment. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a chemical anchor designed to prevent detachment. This invention solves the issues arising during the insertion of the chemical anchor into the pre-embedded hole, where the external washer of the threaded post is movable, making it difficult to limit its movement and thus affecting the stability of the threaded post during insertion; furthermore, the smooth bottom of the washer, after contacting the wall, results in low friction and a tendency to loosen, leading to the displacement and detachment of the threaded post.

[0004] This utility model discloses a chemical anchor bolt for preventing detachment, comprising a threaded post and a chemical agent rod. A nut is provided on the threaded post, and a washer is provided below the nut. A U-shaped limiting frame is provided below the washer, with a through hole in the middle of the U-shaped limiting frame. Multiple equally spaced locking teeth are provided on both sides below the U-shaped limiting frame. An clearance groove matching the washer is provided at the upper end of the U-shaped limiting frame. Four positioning blocks arranged in a matrix are provided below the washer, and a positioning groove matching the positioning blocks is provided below the clearance groove of the U-shaped limiting frame.

[0005] In the above scheme, reinforcing plates are provided at both ends of the U-shaped limiting frame.

[0006] In the above scheme, the U-shaped limiting frame and the reinforcing plate are an integral structure.

[0007] In the above scheme, a hexagonal prism is provided above the threaded column.

[0008] In the above scheme, the threaded column and the hexagonal prism are an integral structure.

[0009] The advantages and beneficial effects of this utility model are as follows: This utility model provides a chemical anchor bolt that prevents detachment. The locking teeth can be embedded into the surface of the component to form a one-way locking structure, effectively preventing relative sliding between the U-shaped limiting frame and the component to be fixed, further improving the overall stability of the anchor bolt. The washer enters the relief groove under the compression of the nut. At the same time, the positioning block is engaged in the positioning groove. Through the mutual cooperation between the positioning block and the positioning groove, the washer can be stably fixed inside the relief groove, effectively preventing the washer from rotating around the axis of the threaded column, thereby avoiding the nut from loosening due to the rotation of the washer, fundamentally solving the problem of washer and nut detachment. This anchor bolt has a simple structure. The locking teeth can be embedded into the surface of the component to form a one-way locking structure. Through the mutual cooperation between the positioning block and the positioning groove, the washer can be stably fixed inside the relief groove, effectively preventing the anchor bolt from detaching.

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] like Figure 1-3As shown, this utility model is a chemical anchor designed to prevent detachment, comprising a threaded post 1 and a chemical agent rod 10. The chemical agent rod 10, after being broken during use, undergoes a solidification reaction with the substrate, achieving a firm bond between the threaded post 1 and the substrate. A nut 2 is provided on the threaded post 1, and a washer 3 is located below the nut 2. A U-shaped retaining bracket 4 is located below the washer 3, with a through hole 5 in the center of the U-shaped retaining bracket 4. The threaded post 1 and the through hole 5 are fitted with a clearance fit, ensuring that the U-shaped retaining bracket 4 can move flexibly along the axis of the threaded post 1 for easy installation and positioning. Multiple equidistant locking teeth 6 are provided on both sides below the U-shaped retaining bracket 4. When the U-shaped retaining bracket 4 contacts the component to be fixed, the locking teeth 6 can embed into the surface of the component, forming a one-way locking structure, effectively preventing the U-shaped retaining bracket 4 from detaching. The relative sliding between the anchor bolt and the component to be fixed further improves the overall stability of the anchor bolt. The upper end of the U-shaped limiting frame 4 is provided with a relief groove 7 that matches the gasket 3. Four positioning blocks 8 are arranged in a matrix below the gasket 3. The U-shaped limiting frame 4 is located below the relief groove 7 and has a positioning groove 9 that matches the positioning blocks 8. When the anchor bolt is installed, the gasket 3 enters the relief groove 7 under the compression of the nut 2. At the same time, the positioning blocks 8 are engaged in the positioning groove 9. Through the mutual cooperation between the positioning blocks 8 and the positioning groove 9, the gasket 3 can be stably fixed inside the relief groove 7, which can effectively prevent the gasket 3 from rotating around the axis of the threaded column 1, thereby preventing the nut 2 from loosening due to the rotation of the gasket 3, and fundamentally solving the problem of the gasket 3 and the nut 2 falling off.

[0017] The U-shaped limiting frame 4 has reinforcing plates 11 on both sides. The reinforcing plates 11 are tightly fitted to the side walls and top of the U-shaped limiting frame 4 to enhance the structural strength of the U-shaped limiting frame 4 and prevent it from deforming under stress.

[0018] The U-shaped limiting frame 4 and the reinforcing plate 11 are an integral structure. The U-shaped limiting frame 4 and the reinforcing plate 11 are manufactured by integral molding process, which not only simplifies the production process, but also effectively improves the connection strength between the U-shaped limiting frame 4 and the reinforcing plate 11, ensuring that the reinforcing plate 11 can fully play its reinforcing role.

[0019] A hexagonal prism 12 is provided above the threaded post 1. During construction, the hexagonal prism 12 can be clamped with tools such as wrenches to facilitate the screwing operation of the threaded post 1 and improve the installation efficiency.

[0020] The threaded post 1 and the hexagonal prism 12 are an integral structure, which effectively ensures the overall structural strength of the anchor bolt.

[0021] Specifically, in this invention, the chemical reagent rod 10 undergoes a solidification reaction with the matrix after being crushed, achieving a firm bond between the threaded column 1 and the matrix. The threaded column 1 and the through hole 5 are fitted with a clearance to ensure that the U-shaped limiting frame 4 can move flexibly along the axis of the threaded column 1, facilitating installation and positioning. When the U-shaped limiting frame 4 contacts the component to be fixed, the locking teeth 6 can embed into the surface of the component, forming a one-way locking structure, effectively preventing relative sliding between the U-shaped limiting frame 4 and the component to be fixed, further improving the overall stability of the anchor bolt. The gasket 3 enters the relief groove 7 under the pressure of the nut 2. At the same time, the positioning block 8 is engaged in the positioning groove 9. Through the mutual cooperation between the positioning block 8 and the positioning groove 9, the gasket 3 can be stably fixed inside the relief groove 7, effectively preventing the gasket 3 from rotating around the axis of the threaded column 1, thereby preventing the nut 2 from loosening due to the rotation of the gasket 3, fundamentally solving the problem of the gasket 3 and the nut 2 falling off.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
