Description

Technical Field

[0001] This utility model relates to the field of concrete processing, and more specifically, to a concrete pile forming device. Background Technology

[0002] Concrete piles are deep foundation components widely used in civil engineering. By driving or pressing the piles into the ground, the load of the superstructure is transferred to deeper soil or rock layers with higher bearing capacity, ensuring the stability and safety of the building. In related technologies, concrete piles can be fabricated in factories or on-site. The process typically involves riveting multiple wooden planks together to form a cavity mold, then pouring concrete into the mold to solidify, and finally removing the wooden planks. This method usually results in a one-time mold that is often destroyed after the concrete pile is formed. Therefore, when producing large quantities of concrete piles, a significant amount of wooden planks are wasted, which is not environmentally friendly and makes it difficult to guarantee the consistency of the final concrete piles. Utility Model Content

[0003] In view of this, the present invention provides a recyclable concrete pile forming device.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A concrete pile forming device includes: a base plate, two first side plates, and two second side plates; the two first side plates are respectively disposed on opposite sides of the base plate, and each first side plate is hinged to the base plate; the two second side plates are respectively disposed on the other opposite sides of the base plate, and each second side plate is hinged to the base plate; wherein the base plate, the two first side plates, and the two second side plates can be spliced ​​to form a cavity with a top opening; a locking assembly and a positioning assembly are provided between adjacent first side plates and second side plates, the locking assembly being used to fix adjacent first side plates and second side plates together, and the positioning assembly being used to position the adjacent first side plates and second side plates after splicing.

[0006] In the above technical solution, by designing the base plate, first side plate, and second side plate as hinged connections, the forming device can be easily unfolded and folded, facilitating transportation and storage, and making transfer between multiple construction sites more efficient. It also increases the reusability of the device, making construction more environmentally friendly. The locking assembly not only secures the adjacent side plates but also enhances the structural stability of the entire device. During concrete pouring, the device can withstand significant pressure without deformation or displacement, ensuring the forming quality of the concrete pile. The positioning assembly ensures that adjacent first and second side plates maintain a precise positional relationship after splicing, thereby guaranteeing the shape and consistency of the concrete pile forming cavity.

[0007] Optionally, in one possible implementation, a first annular frame is provided on the side of the first side plate away from the cavity, and a second annular frame is provided on the side of the second side plate away from the cavity, with the locking assembly disposed on the first and second annular frames.

[0008] In the above technical solution, the first and second annular frames facilitate the installation of the locking components, provide a larger contact area and a more uniform force distribution for the locking components, and enable the locking components to more effectively fix the side plates and prevent loosening or displacement during concrete pouring.

[0009] Optionally, in one possible implementation, the locking assembly includes a fixing block, a connecting block, and a locking member. The fixing block is disposed on the first annular frame, the connecting block is disposed on the second annular frame, and the locking member is used to fix the fixing block and the connecting block.

[0010] In the above technical solution, when the locking assembly is locking, the adjacent first side plate and second side plate are first folded to the predetermined position by the positioning component. At this time, the fixing block and the connecting block are opposite each other. Then, the locking component fixes the fixing block and the connecting block relative to each other. The operation is simple and convenient, and a stable and reliable connection between the first side plate and the second side plate is achieved, which effectively prevents molding quality problems caused by the displacement or loosening of the side plate during the concrete pouring process.

[0011] Optionally, in one possible implementation, the fixing block is provided with a threaded hole, the connecting block is provided with a groove, the locking member includes a threaded section and a limiting section arranged coaxially, the threaded section passes through the groove and is threadedly connected to the threaded hole, and the end of the limiting section near the threaded section abuts against the connecting block.

[0012] In the above technical solution, a precise and stable connection is formed between the locking element and the fixing block through the threaded connection between the threaded section and the threaded hole. At this time, the limiting section abuts against and squeezes the surface of the connecting block, thereby achieving relative fixation of the fixing block, the connecting block and the locking element. The self-locking ability of the thread and the friction between the limiting section and the connecting block can ensure the stability of the locking and prevent the side plate from loosening or shifting.

[0013] Optionally, in one possible implementation, a plurality of handles are provided on the outer periphery of the limiting segment, and the handles extend radially outward along the limiting segment.

[0014] In the above technical solution, the handle design provides operators with an intuitive and comfortable grip. When installing or removing the locking mechanism, operators can directly grasp the handle and rotate it without the need for additional tools, allowing for quick and accurate installation and removal of the locking mechanism.

[0015] Optionally, in one possible implementation, the connecting block has a limiting groove on the side away from the fixing block, the limiting groove and the groove forming a stepped groove structure, and the limiting segment is engaged in the limiting groove.

[0016] In the above technical solution, the setting of the limiting groove can further enhance the locking stability between the locking component and the connecting block. The groove can improve the fault tolerance rate of the alignment with the threaded hole, ensuring that the locking component can be accurately inserted into the threaded hole after passing through the groove. The limiting groove can further restrict the radial displacement of the locking component, making it less likely for the locking component to loosen or fall off when subjected to external force.

[0017] Optionally, in one possible implementation, a third annular frame is provided on the side of the base plate away from the cavity, and a plurality of first extension plates are provided on the outer side of the third annular frame. The first extension plates are provided with slots, and a second extension plate is provided on both the first and second annular frames. The second extension plates are rotatably installed in the slots of the corresponding first extension plates via a rotating shaft.

[0018] In the above technical solution, by setting a third annular frame on the base plate and using the first extension plate and the second extension plate to be rotatably connected by a pivot, a stable frame support structure is formed, which makes the space formed inside the cavity more regular. Furthermore, the pivot connection method allows the side plates and the base plate to be flexibly folded, facilitating transportation and storage.

[0019] Optionally, in one possible implementation, the first annular frame, the second annular frame, and the third annular frame are each provided with a plurality of reinforcing ribs.

[0020] In the above technical solution, the reinforcing ribs can effectively enhance the bending and torsional resistance of the frame, making the device less prone to deformation or breakage when subjected to concrete pouring pressure and construction vibration, ensuring the stability and reliability of the overall structure of the device, and meeting the requirements of high-intensity construction.

[0021] Optionally, in one possible implementation, the positioning component includes a positioning hole disposed on the first side plate and a positioning post disposed on the second side plate, the positioning post being insertable into the positioning hole.

[0022] In the above technical solution, the first and second side plates can be quickly and accurately aligned during splicing by the insertion and cooperation of the positioning column and the positioning hole, without the need for repeated adjustments or measurements, which significantly shortens the installation time and improves construction efficiency.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] Please refer to Figure 1 and Figure 2 This embodiment provides a concrete pile forming device, including: a base plate 1, two first side plates 2, and two second side plates 3; the two first side plates 2 are respectively disposed on opposite sides of the base plate 1, and each first side plate 2 is hinged to the base plate 1; the two second side plates 3 are respectively disposed on the other opposite sides of the base plate 1, and each second side plate 3 is hinged to the base plate 1; wherein, the base plate 1, the two first side plates 2, and the two second side plates 3 can be spliced ​​to form a cavity with a top opening; a locking component 4 and a positioning component 5 are provided between adjacent first side plates 2 and second side plates 3, the locking component 4 is used to fix adjacent first side plates 2 and second side plates 3, and the positioning component 5 is used to position the adjacent first side plates 2 and second side plates 3 after splicing.

[0033] This embodiment designs the base plate 1, first side plate 2, and second side plate 3 with a hinged connection. This allows the molding device to be easily unfolded and folded, facilitating transportation and storage, and making transfer between multiple construction sites more efficient. It also increases the device's reusability and makes construction more environmentally friendly. The locking component 4 not only secures the adjacent side plates but also enhances the overall structural stability of the device. During concrete pouring, the device can withstand significant pressure without deformation or displacement, ensuring the molding quality of the concrete pile. The positioning component 5 ensures that the adjacent first side plate 2 and second side plate 3 maintain a precise positional relationship after splicing, thereby guaranteeing the shape and consistency of the concrete pile molding cavity.

[0034] In this embodiment, a first annular frame 21 is provided on the outer side of the first side plate 2, that is, on the side away from the cavity, and a second annular frame 31 is provided on the outer side of the second side plate 3, that is, on the side away from the cavity. The locking assembly 4 is disposed on the first annular frame 21 and the second annular frame 31. The first annular frame 21 is close to the periphery of the first side plate 2, and the second annular frame 31 is close to the outer periphery of the second side plate 3. The annular frames extend outward from the outer surface of the corresponding side plate and are perpendicular to the outer surface of the corresponding side plate.

[0035] The arrangement of the first annular frame 21 and the second annular frame 31 facilitates the installation of the locking assembly 4, providing it with a larger contact area and a more uniform force distribution. This allows the locking assembly 4 to more effectively secure the side plate, preventing loosening or displacement during concrete pouring. Furthermore, the annular frame design helps optimize the force distribution of the device during concrete pouring. When concrete applies pressure to the side plate, the annular frame can evenly transmit the pressure to the locking assembly 4 and adjacent side plates, avoiding structural damage caused by localized stress concentration, thereby improving the stability and safety of the device.

[0036] In this embodiment, the locking assembly 4 includes a fixing block 41, a connecting block 42, and a locking member 43. The fixing block 41 is disposed on the first annular frame 21, the connecting block 42 is disposed on the second annular frame 31, and the locking member 43 is used to fix the fixing block 41 and the connecting block 42.

[0037] When locking, the locking assembly 4 first uses the positioning assembly 5 to fold the adjacent first side plate 2 and second side plate 3 to a predetermined position. At this time, the fixing block 41 and the connecting block 42 are opposite each other and in contact with each other. Then, the locking member 43 fixes the fixing block 41 and the connecting block 42 relative to each other. The operation is simple and convenient, and a stable and reliable connection between the first side plate 2 and the second side plate 3 is achieved, which effectively prevents molding quality problems caused by side plate displacement or loosening during concrete pouring.

[0038] For details, please refer to Figure 3 and Figure 4 The fixing block 41 has a threaded hole 411, and the connecting block 42 has a groove 421. The locking member 43 includes a threaded section 431 and a limiting section 432 arranged coaxially. Both the threaded section 431 and the limiting section 432 are cylindrical structures, and the diameter of the limiting section 432 is larger than that of the threaded section 431. A stepped shaft structure is formed between the threaded section 431 and the limiting section 432. The threaded section 431 passes through the groove 421 and is threadedly connected to the threaded hole 411. The end of the limiting section 432 near the threaded section 431 abuts against the connecting block 42. Alternatively, the groove 421 can be replaced by a through hole structure, that is, the threaded section 431 can pass through the through hole and be threadedly connected to the threaded hole 411.

[0039] Through the threaded connection between the threaded section 431 and the threaded hole 411, a precise and stable connection is formed between the locking member 43 and the fixing block 41. At this time, the limiting section 432 abuts against and presses the surface of the connecting block 42, thereby achieving relative fixation of the fixing block 41, the connecting block 42 and the locking member 43. The self-locking ability of the thread and the friction between the limiting section 432 and the connecting block 42 can ensure the stability of the lock and prevent the side plate from loosening or shifting.

[0040] In this embodiment, several handles 4321 are provided on the outer periphery of the limiting section 432, and the handles 4321 extend radially outward along the limiting section 432. Two handles 4321 can be symmetrically arranged, providing the operator with an intuitive and comfortable grip. When installing or removing the locking component 43, the operator can directly grasp the handles 4321 and rotate them without the need for additional tools, allowing for quick and accurate installation and removal of the locking component 43. Furthermore, a hexagonal hole 4322 can be provided at the end of the limiting section 432 away from the threaded section 431, allowing for hexagonal insertion. This allows for the use of auxiliary tools when a stronger locking force is required.

[0041] In this embodiment, a limiting groove 422 is provided on the side of the connecting block 42 away from the fixing block 41. The limiting groove 422 and the groove 421 form a stepped groove structure, and the limiting segment 432 is engaged in the limiting groove 422. The limiting groove 422 is a circular groove 421, and the diameter of the limiting groove 422 is larger than the diameter of the limiting segment 432. The setting of the limiting groove 422 can further enhance the locking stability between the locking member 43 and the connecting block 42. The groove 421 can improve the fault tolerance rate of the alignment with the threaded hole 411, ensuring that the locking member 43 can be accurately inserted into the threaded hole 411 after passing through the groove 421. The limiting groove 422 can further restrict the radial displacement of the locking member 43, making it less likely for the locking member 43 to loosen or fall off when subjected to external force.

[0042] Please refer to Figure 5 It should be noted that a third annular frame 11 is provided on the side of the base plate 1 away from the cavity. Multiple first extension plates 111 are provided on the outer side of the third annular frame 11. The first extension plates 111 are provided with slots (not shown in the figure). The first annular frame 21 and the second annular frame 31 are both provided with second extension plates 211. The second extension plates 211 are rotatably installed in the slots of the corresponding first extension plates 111 through the rotating shaft 6.

[0043] By setting a third annular frame 11 on the base plate 1 and using the first extension plate 111 and the second extension plate 211 to be rotatably connected by a pivot 6, a stable frame support structure is formed, which makes the space formed inside the cavity more regular. Furthermore, the connection method using the pivot 6 allows the side plates and the base plate 1 to be flexibly folded, facilitating transportation and storage.

[0044] Furthermore, in this embodiment, the first annular frame 21, the second annular frame 31, and the third annular frame 11 are all provided with a plurality of reinforcing ribs 7. The reinforcing ribs 7 are "X" shaped structures or triangular structures. The reinforcing ribs 7 can effectively enhance the bending and torsional resistance of the frame, making the device less prone to deformation or breakage when subjected to concrete pouring pressure and construction vibration, ensuring the stability and reliability of the overall structure of the device, and meeting the requirements of high-intensity construction.

[0045] In this embodiment, the positioning component 5 includes a positioning hole 51 disposed on the first side plate 2 and a positioning post 52 disposed on the second side plate 3. The positioning post 52 can be inserted into the positioning hole 51. Through the insertion and cooperation of the positioning post 52 and the positioning hole 51, the first side plate 2 and the second side plate 3 can quickly achieve precise alignment during splicing without repeated adjustments or measurements, significantly shortening the installation time and improving construction efficiency.
