Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a lightweight, high-strength prefabricated component. Background Technology

[0002] Lightweight, high-strength precast components are building components prefabricated in factories. They are characterized by their light weight and high strength and are widely used in prefabricated buildings. Through optimized design and material selection, these precast components significantly reduce the weight of the components while ensuring structural strength, thereby reducing transportation and installation costs and improving construction efficiency.

[0003] A search revealed Chinese Patent Publication No. CN215406511U, which discloses a precast component, including a precast component body. The precast component body has a cast-in-place cavity located within the body and near its side edge. A pouring port is provided on the side edge of the precast component body, connecting to the cast-in-place cavity. The precast component body also includes a vibrator channel, one end of which communicates with the cast-in-place cavity, and the other end connects to the outside of the precast component body.

[0004] However, in actual use, the above-mentioned device has the problem that when it is necessary to extend the fixed plate of the injection molding, it cannot effectively extend the internal structure. This makes it necessary to move and replace the internal frame back and forth during application. This not only increases the complexity of design and production, but also leads to a reduction in production efficiency. Therefore, a lightweight high-strength precast component is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lightweight, high-strength precast component, which aims to improve the problem that some existing devices cannot properly extend the internal precast components when extended grouting slurry needs to be solidified.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lightweight, high-strength precast component includes a grouting chamber, a central plate slidably connected inside the grouting chamber, extension mechanisms on both outer sides of the central plate, a tilting mechanism on both outer sides of the central plate, and a support mechanism on the inner wall of the central plate and the extension mechanisms.

[0008] The extension mechanism includes two sliding blocks, which are slidably connected to the outer side of the central plate. Rotating columns are rotatably connected to both outer sides of the two sliding blocks. An extension plate is rotatably connected to the outer side of the two rotating columns. Multiple arc-shaped tubes are fixedly connected to the outer side of the two extension plates, i.e., the outer side away from the central plate. Limiting components are slidably connected to the outer side of the two extension plates. Multiple alignment grooves are opened on the top of the central plate. Multiple positioning rods are slidably connected to the inner bottom wall of the two extension plates. Multiple support rods are fixedly connected to the outer side of the extension plates, i.e., the outer side away from the central plate.

[0009] The above technical solution involves a sliding block that slides on the central plate, causing the rotating column to rotate and thus extending the plate along the top of the central plate. After extension, the positioning rod slides into the alignment groove at the top of the central plate, providing stable support for the extended plate. Simultaneously, the arc-shaped tube and support rod provide additional support and stability, ensuring the stability of the extended plate during use.

[0010] As a further description of the above technical solution:

[0011] The limiting component includes two sliding grooves. The two sliding grooves are formed on the outside of the two extension plates, i.e., on the side away from the center plate. A sliding rod is slidably connected inside the sliding groove. The outside of the sliding rod passes through the sliding groove and the outside of the center plate in sequence. The outside of the sliding rod is at the bottom of the arc-shaped tube, and the outside of the support rod is at the bottom of the arc-shaped tube.

[0012] Through the above technical solution, the sliding rod can slide in the sliding groove. When extension is not required, the sliding rod passes through the sliding groove to fix the extension plate on both sides of the central plate to prevent it from shifting, thereby maintaining the stability of the structure in the non-working state.

[0013] As a further description of the above technical solution:

[0014] The tilting mechanism includes two support rods, the outer side of the two support rods is on the outer side of the central plate, and a support block is fixedly connected to the outer side of the two support rods.

[0015] The above technical solution involves fixing the support rod to one side of the outer side of the central plate, with a support block connected to its exterior, providing stable support and a connection foundation for the tilting mechanism.

[0016] As a further description of the above technical solution:

[0017] A sliding rod is slidably connected to an adjacent side of the support block, and a connecting block is rotatably connected to the outside of the sliding rod.

[0018] Through the above technical solution, the slide bar can slide smoothly inside the support block, enabling rapid installation and support. At the same time, it can penetrate the interior of the connecting block during sliding, allowing the connecting block to rotate.

[0019] As a further description of the above technical solution:

[0020] A pressing rod is fixedly connected to the outside of the connecting block, i.e., the side away from the center plate, and the outside of the connecting block is on the adjacent side of the two extension plates.

[0021] The above technical solution allows for precise control of the tilting amplitude and position of the central plate and extension plate through the movement of the pressing rod, ensuring that the grout can be evenly distributed during the grouting process of the precast components, while preventing air residue and improving the quality and performance of the components.

[0022] As a further description of the above technical solution:

[0023] The support mechanism includes multiple connecting rods, which are externally fixedly connected to the interior of the central plate and the two extension plates. Multiple support columns are fixedly connected to the interior of the central plate and the two extension plates.

[0024] Through the above technical solution, the connecting rods and supports cooperate to form a mesh structure, which further enhances the internal stability of the precast components.

[0025] As a further description of the above technical solution:

[0026] Multiple base rods are fixedly connected to the bottom of the two extension plates, and the exterior of the multiple support columns is on top of the multiple base rods.

[0027] Through the above technical solution, the bottom rod can effectively disperse and transmit the pressure generated during the grouting process, and enhance the toughness of the precast components after molding.

[0028] As a further description of the above technical solution:

[0029] The multiple connecting rods and multiple supporting columns penetrate each other to form a mesh structure, which is fixedly connected inside the central plate and the two extension plates.

[0030] Through the above technical solution, the mesh structure is fixedly connected inside the central slab and the two extension slabs, providing internal support for the prefabricated components.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the sliding block and rotating column drive the extension plate to slide towards the top of the central plate, thereby extending the central plate. Its design can flexibly adjust the size of the stone slab to meet the needs of different usage scenarios, and can also significantly enhance its support capacity after the slurry solidifies, thereby improving the overall stability and load-bearing performance of the precast components.

[0033] 2. In this utility model, a stable support foundation is provided by the support rod and the support block. The sliding rod slides inside the support block, driving the connecting block to move, ensuring the stability of the precast component during the grouting process, preventing structural deformation or uneven grout distribution caused by vibration or impact, and at the same time, it can be easily disassembled and maintained when not in use, further improving the flexibility and maintenance convenience of the mechanism.

[0041] 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.

[0042] Reference Figures 3 to 5 The present invention provides an embodiment of a lightweight high-strength precast component, including a grouting chamber 1, which is designed to be hollow inside so that grout can be injected. A central plate 2 is slidably connected inside the grouting chamber 1, which can provide good support. By sliding inside the grouting chamber 1, it is fixed inside the grout during grout injection, which provides internal support for the formed stone slab and reduces the weight of the stone slab. Extension mechanisms 3 are provided on both sides of the outer side of the central plate 2, and tilting mechanisms 5 are provided on both sides of the outer side of the central plate 2. Supporting mechanisms 6 are provided on the inner walls of the central plate 2 and the extension mechanisms 3.

[0043] The extension mechanism 3 includes two sliding blocks 37, designed to provide good sliding ability, allowing sliding on both sides and ends of the outer surface of the central plate 2. The two sliding blocks 37 are externally slidably connected to one side of the outer surface of the central plate 2. Rotating columns 32 are rotatably connected to both sides of the outer surface of the two sliding blocks 37, designed to provide good rotation ability. An extension plate 31 is rotatably connected to one side of the outer surface of the two rotating columns 32, designed to provide additional support. At the same time, when the rotating columns 32 connected through the sliding blocks 37 rotate, they can drive the extension plate 31 to rotate smoothly. This allows the extension plates 31 to slide on top of the central plate 2 for additional extension. Multiple arc-shaped tubes 33 are fixedly connected to the outer sides of the two extension plates 31, i.e., the outer side away from the central plate 2. Their design provides good support for the extension plates 31. Limiting components 4 are slidably connected to the outer sides of the two extension plates 31. The limiting components 4 include two sliding grooves 402, designed to provide good sliding space. The two sliding grooves 402 are located on the outer sides of the two extension plates 31, i.e., the outer side away from the central plate 2. The internal sliding connection of plate 2 includes a sliding rod 401. The sliding space provided within the sliding groove 402 allows the sliding rod 401 to slide within the groove 402. This design limits the extension plate 31 when it is not needed for extension, preventing displacement. The outer side of the sliding rod 401 passes through the sliding groove 402 and one side of the central plate 2. The outer side of the sliding rod 401 is at the bottom of the arc-shaped tube 33, and the outer side of the support rod 36 is at the bottom of the arc-shaped tube 33. Multiple alignment grooves 34 are provided on the top of the central plate 2. The design provides good alignment capability. Multiple positioning rods 35 are slidably connected to the inner bottom walls of the two extension plates 31. Supported by the inner bottom walls of the extension plates 31, they can slide on the inner bottom walls of the extension plates 31. When the extension plates 31 slide to the top of the center plate 2, pulling down the positioning rods 35 can slide the positioning rods 35 into the interior of the alignment groove 34, which provides good support for the extension plates 31 when they are on the top of the center plate 2. Multiple support rods 36 are fixedly connected to the outer side of the extension plates 31, i.e. the outer side away from the center plate 2. The design provides good stability capability.

[0044] Specifically, when grouting is carried out inside the grouting chamber 1, the central plate 2 is slidably placed inside the grouting chamber 1 and fixed in the grout during grouting, serving as internal support and reducing the weight of the stone slab. When it is necessary to enlarge the size of the stone slab, the sliding block 37 slides on the central plate 2, and the rotating column 32 can slide along with it, driving the extension plate 31 to slide towards the top of the central plate 2. After sliding, the positioning rod 35 on the inner bottom wall of the extension plate 31 is slid through the bottom of the extension plate 31, so that the positioning rod 35 can slide inside the alignment groove 34, which can provide good support for the extension plate 31. At the same time, the arc-shaped tube 33 near the top of the extension plate 31 provides additional support and grouting capacity. When extension is not required, the sliding rod 401 is passed through the sliding groove 402 to fix the extension plate 31 to the outer sides of the central plate 2, which can prevent displacement.

[0045] Reference Figure 1 and Figure 2 The tilting mechanism 5 includes two support rods 51, designed to provide good support. The outer sides of the two support rods 51 are located on one side of the central plate 2. Support blocks 52 are fixedly connected to the outer sides of the two support rods 51, providing good connection to the support blocks 52 through the support of the support rods 51. A sliding rod 53 is slidably connected to the adjacent side of the support block 52, allowing it to slide inside the support block 52. This design provides good support and rotation capabilities, and allows the sliding rod 53 to be slid out and disassembled when not in use. A connecting block 54 is rotatably connected to the outer side of the sliding rod 53, allowing it to slide and rotate outside the sliding rod 53. When the adjacent side of the support block 52 is in contact with the outside of the slide bar 53, the connecting block 54 can also be disassembled. The outside of the connecting block 54, that is, the side away from the center plate 2, is fixedly connected to the pressing rod 55. Its design can provide good prying ability. When the bottom of the pressing rod 55 near the slide bar 53 is in contact with the top of the grouting chamber 1, pressing the pressing rod 55 allows the connected center plate 2 and extension plate 31 to slide up and down through the lever principle. Its design can fully spread the injected mud inside the center plate 2 and extension plate 31 to prevent air from being generated. After the sliding is completed, the pressing rod 55 can be removed by sliding the slide bar 53 out. The outside of the connecting block 54 is on the adjacent side of the two extension plates 31.

[0046] Specifically, a stable support base is provided by support rod 51 and support block 52. Sliding rod 53 slides inside support block 52, driving connecting block 54 to move. Connecting block 54 then achieves a prying function through pressing rod 55, allowing it to be pried on both sides of the top of grouting chamber 1. This design not only ensures the stability of precast components during grouting but also achieves efficient grout laying through leverage, preventing air residue. Furthermore, the detachable design of sliding rod 53 and pressing rod 55 further improves the flexibility and ease of maintenance of the mechanism.

[0047] Reference Figure 3 and Figure 4 The support mechanism 6 includes multiple connecting rods 61, which are designed to provide good connection capabilities. The external of the multiple connecting rods 61 is fixedly connected to the interior of the central plate 2 and the two extension plates 31. Multiple support columns 62 are fixedly connected to the interior of the central plate 2 and the two extension plates 31, which are designed to provide good support capabilities. Multiple bottom rods 63 are fixedly connected to the bottom of the two extension plates 31, which are designed to provide good fixation capabilities during slurry injection and enhance the toughness of the interior of the wall after molding. The external of the multiple support columns 62 is on top of the multiple bottom rods 63. The multiple connecting rods 61 and the multiple support columns 62 are interconnected to form a mesh structure, which is fixedly connected to the interior of the central plate 2 and the two extension plates 31.

[0048] Specifically, a mesh structure is formed by the interconnection and penetration of connecting rods 61 and pillars 62, which is fixedly connected inside the central plate 2 and the two extension plates 31. Connecting rods 61 provide vertical connection capability, pillars 62 provide lateral support capability, and bottom rods 63 provide bottom fixation capability. The design of the entire mesh structure allows force to be evenly distributed among the components, enhancing the stability and load-bearing capacity of the precast components, ensuring uniform support during the grouting process and toughness after molding, while reducing cracking caused by vibration of the stone slab.

[0049] Working Principle: When prefabricated components need to be manufactured, the central slab 2 is first slidably placed inside the grouting chamber 1. Then, grout is poured in. At this time, the central slab 2 is fixed in the grout, providing internal support and reducing the weight of the slab. If the size of the slab needs to be increased, the sliding block 37 slides on the central slab 2, causing the rotating column 32 to rotate, which in turn causes the extension plate 31 to slide towards the top of the central slab 2, thus extending the extension plate 31. After extension, the sliding positioning rod 35 passes through the bottom of the extension plate 31 and slides into the alignment groove 34 at the top of the central slab 2, providing stable support for the extension plate 31. At this time, the arc-shaped tube 33 also provides additional support for the extension plate 31 and enhances the grouting capacity. If extension is not required, the sliding rod 401 passes through the sliding groove 402, fixing the extension plate 31 to both sides of the central slab 2 to prevent displacement. Meanwhile, connecting rods 61 and pillars 62 are interconnected and run through each other, forming a mesh structure that is fixedly connected to the interior of the central plate 2 and the two extension plates 31. Connecting rods 61 provide connection capability, pillars 62 provide support capability, and bottom rods 63 provide fixation capability at the bottom of the extension plates 31. The entire mesh structure allows force to be evenly transmitted between the components, enhancing the stability and load-bearing capacity of the precast components, ensuring uniform support during the grouting process and toughness after molding, and reducing the risk of slab cracking due to vibration.

[0050] The support rod 51 and support block 52 provide a stable support foundation for the entire tilting mechanism 5. When grouting is required, the slide rod 53 slides inside the support block 52 to the appropriate position, driving the connecting block 54 to move. At this time, the bottom of the pressing rod 55 on the connecting block 54 near the slide rod 53 is in contact with the top of the grouting chamber 1. By pressing the pressing rod 55, the connected central plate 2 and extension plate 31 slide up and down using the lever principle, so that the grouting slurry can be fully laid inside the central plate 2 and extension plate 31, avoiding air residue. After the grouting is completed, the slide rod 53 is slid out of the support block 52, so that the pressing rod 55 can be removed, thus completing the entire tilting operation. This design not only ensures the stability of the precast components during the grouting process, but also improves the efficiency of grouting. At the same time, the detachable design of the slide rod 53 and pressing rod 55 facilitates maintenance and replacement.

Although the present utility model 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.
