Description

Technical Field

[0001] This utility model relates to the field of precast concrete components, and in particular to a high-strength precast concrete component. Background Technology

[0002] Precast concrete components refer to assembled concrete components that have been manufactured before installation on the construction site. Common examples include precast concrete floor slabs, concrete box girders for bridges, precast concrete roof trusses for industrial plants, culvert frames, and precast concrete piles for foundation treatment.

[0003] A search revealed Chinese patent CN219157972U, which discloses a precast concrete component body. One end of the precast concrete component body is fixedly provided with an insert block, and the other end has a slot for inserting another precast concrete component body. A sliding groove is formed on the insert block along the height direction of the precast concrete component body. Two limiting blocks are slidably arranged in the sliding groove in directions that are close together or far apart. Limiting grooves for inserting the two limiting blocks are respectively formed on the side walls of the slot. A driving mechanism for driving the two limiting blocks to slide is provided within the insert block. This application has the effect of improving the stability of buildings.

[0004] The aforementioned technical support operations are cumbersome, which not only prolongs the installation or fixing time and reduces construction efficiency, but also increases the difficulty of operation and physical exertion for users. Especially in scenarios where support work needs to be completed quickly, the complexity of the steps can easily lead to operational errors, affecting the stability and reliability of the support effect. At the same time, the cumbersome process may also cause inconvenience to users during use, which is not conducive to improving the overall construction experience and work progress.

This simple pulling operation greatly simplifies the usage process, allowing users to quickly and efficiently install and fix components, improving ease of operation and practicality.

[0042] 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. Example 1

[0043] Please see Figure 1 - Figure 4 This embodiment provides a high-strength precast concrete component that facilitates quick and easy positioning of the first precast component 1 and the second precast component 101. The specific concept is as follows:

[0044] The high-strength precast concrete component includes a first precast component 1 and a second precast component 101. In addition, the high-strength precast concrete component also includes a limiting member disposed on the outer side of one end of the first precast component 1. The limiting member can quickly and initially limit the second precast component 101 to one side of the first precast component 1, which facilitates subsequent limiting operations without complicated operation steps and reduces the skill requirements of the operators.

[0045] The limiting component in this embodiment includes: a support leg 201 fixedly connected to the outer side of one end of the first prefabricated component 1, the support leg 201 being used to support the mounting frame 2; a connecting block 202 movably connected to the inner side of the end of the mounting frame 2; a limiting block 203 slidably connected to the inner side of the end of the mounting frame 2; a top block 204 fixedly connected to the outer side of one end of the limiting block 203, the top block 204 being used to limit and support the second prefabricated component 101; and a first slot 207 formed on the inner side of one end of the second prefabricated component 101. Multiple first springs 206 are fixedly connected to the inner side of one end of the 2. The outer side of the end of the first spring 206 is fixedly connected to one side of the connecting block 202. The first spring 206 is used to support the connecting block 202. A handle 205 for pulling itself to move is fixedly connected to one side of the connecting block 202. A trapezoidal protrusion is provided on the outer side of the end of the connecting block 202. A trapezoidal through groove is opened on the inner side of the end of the limiting block 203. The trapezoidal protrusion at the end of the connecting block 202 is connected to the inner side of the trapezoidal through groove opened at the end of the limiting block 203.

[0046] In the specific implementation process: When using the device, the user can pull the connecting block 202 through the handle 205. While the connecting block 202 is moving, it will compress the first spring 206 and store elastic potential energy. At this time, the connecting block 202 moves towards the inside of the mounting bracket 2. At the same time, the connecting block 202 will match the trapezoidal through groove on one side of the limiting block 203 through the trapezoidal protrusion on the outer side of its end, thereby pulling multiple limiting blocks 203 to move towards the center, and at the same time driving the top block 204 to move. At this time, the user can insert the mounting bracket 2 into the inside of the first slot 207. At this time, the user can release the handle 205. At the same time, the elastic potential energy of multiple first springs 206 is released, which will push the connecting block 202 to move outward. While the connecting block 202 is moving, it will push multiple limiting blocks 203 to drive the top block 204 to move, thereby supporting the inner wall surface of the first slot 207 through the top block 204. Example 2

[0047] Please see Figure 5 - Figure 7 This embodiment provides another high-strength precast concrete component that facilitates rapid positioning of the first precast component 1 and the second precast component 101. The specific concept is as follows:

[0048] The high-strength precast concrete component includes a first precast component 1 and a second precast component 101. Furthermore, the high-strength precast concrete component also includes an inner support member disposed on the outer side of one end of the first precast component 1. This inner support member can quickly and initially limit the second precast component 101 to one side of the first precast component 1, facilitating subsequent limiting operations without requiring complex steps, thus reducing the skill requirements for operators. Simultaneously, the inner support member ensures that the greater the tension between the first precast component 1 and the second precast component 101, the more firmly the inner support member limits the second precast component 101, further increasing the stability of the connection between the first precast component 1 and the second precast component 101.

[0049] The internal support in this embodiment includes: a chassis 301 fixedly connected to the outer side of one end of the first precast component 1; a sliding rod 302 fixedly connected to one side of the chassis 301; a sliding sleeve 303 slidably connected to the outer side of the sliding rod 302, and the sliding sleeve 303 moves along the outer side of the sliding rod 302; a fixed sleeve 304 fixedly connected to the outer side of the end of the sliding rod 302; a first rotating arm 305 rotatably connected to the inner side of the end of the fixed sleeve 304; a second rotating arm 306 rotatably connected to the inner side of the end of the fixed sleeve 304, with the first rotating arm 305 and the second rotating arm 306 arranged in parallel; and a third rotating arm 307 rotatably connected to the inner side of the end of the sliding sleeve 303. The first rotating arm 305, the second rotating arm 306, and the third rotating arm 307 are rotatably connected to the inner side of the end of the sliding sleeve 303. The outer side of the end of 7 is connected to the inner side of the end of the top plate 3, thereby driving multiple top plates 3 to move and retract outward. The second slot 312 is opened on the inner side of the end of the second prefabricated component 101. A pull cylinder 309 is fixedly connected to one side of the sliding sleeve 303. A second spring 308 is fixedly connected to one side of the chassis 301. The outer side of the end of the second spring 308 is connected to the inner side of the pull cylinder 309. The pull cylinder 309 can be supported by the second spring 308. Multiple insertion holes 310 are opened on the outer side of the pull cylinder 309. The user can pull the pull cylinder 309 through the insertion holes 310, thereby driving the sliding sleeve 303 to slide on the outside of the sliding rod 302. A gasket 311 is fixedly connected to one side of the top plate 3 to increase friction.

[0050] In the specific implementation process: When using the device, the user can first pull the pull cylinder 309 through the insertion hole 310, simultaneously compressing the second spring 308 and storing elastic potential energy. When the pull cylinder 309 moves, it will drive the sliding sleeve 303 to move. While the sliding sleeve 303 moves, it will pull multiple third rotating arms 307 towards the chassis 301. When the third rotating arms 307 rotate, they will drive the top plate 3 to move, thereby driving multiple first rotating arms 305 and second rotating arms 306 to rotate, so that the top plate 3 can retract inward. At this time, it is inserted into the inside of the second slot 312. Then, the pull cylinder 309 is released, and the second spring 308 releases its elastic potential energy, pushing the pull cylinder 309 and the sliding sleeve 303 towards the chassis 301. The top plate 3 moves towards the fixed sleeve 304 and simultaneously pushes the first rotating arm 305, the second rotating arm 306, and the third rotating arm 307 outward to rotate. This causes multiple top plates 3 to expand outward and contact the inner wall of the second slot 312 through the gasket 311, thus limiting the second prefabricated component 101. At the same time, when an external force pulls the second prefabricated component 101, the top plate 3 will tend to move towards the fixed sleeve 304, which will again cause the first rotating arm 305, the second rotating arm 306, and the third rotating arm 307 to rotate outward. While rotating, the top plate 3 will expand outward again, thereby increasing the support force on the inner wall of the second slot 312.

[0051] Working principle:

[0052] Building upon Embodiment 1, this design offers the advantage that users can easily move the connecting block 202 and compress the first spring 206 to store elastic potential energy simply by pulling the handle 205. Simultaneously, the trapezoidal protrusion on the outer side of the connecting block 202 matches the trapezoidal slot on one side of the limiting block 203, causing multiple limiting blocks 203 and the top block 204 to move towards the center. Afterward, the mounting bracket 2 is inserted into the inner side of the first slot 207, and the handle 205 is released. The elastic potential energy released by the first spring 206 then pushes the connecting block 202, limiting blocks 203, and top block 204 to move, ultimately supporting the inner wall of the first slot 207 through the top block 204. This simple pulling operation greatly simplifies the usage process, allowing users to quickly and efficiently install and fix components, thus improving the convenience and practicality of the operation.

[0053] Based on Embodiment 2, the operation process is simple. The user only needs to pull the socket 310 to move the pull cylinder 309 and compress the second spring 308 to store elastic potential energy. This, in turn, drives the sliding sleeve 303, multiple third rotating arms 307, top plate 3, first rotating arm 305, and second rotating arm 306 in a coordinated manner, causing the top plate 3 to retract inward. Then, it is inserted into the inside of 312 and the pull cylinder 309 is released. The elastic potential energy released by the second spring 308 can then push the pull cylinder 309 and the sliding sleeve 303 to move, causing the first rotating arm 305, second rotating arm 306, and third rotating arm 307 to rotate, causing the multiple top plates 3 to expand outward. This is achieved through the gasket 311 and 3 The inner wall of 12 achieves the limiting of the second prefabricated component 101; more importantly, when an external force pulls the second prefabricated component 101, the top plate 3 tends to move towards the fixed sleeve 304, which will again drive the first rotating arm 305, the second rotating arm 306, and the third rotating arm 307 to rotate outward, allowing the top plate 3 to expand further outward and increase the support force on the inner wall of 312. This design not only allows the top plate 3 to contract and expand simply by pulling the insertion hole 310, making it convenient and quick to complete the installation and limiting, but also forms an adaptive reinforcement effect when an external force pulls the second prefabricated component 101, improving the convenience, stability, and reliability of the component.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
