Description

Technical Field

[0001] This utility model relates to the field of highway engineering construction technology, specifically to a prefabricated curbstone mold device. Background Technology

[0002] In Côte d'Ivoire, Africa, longitudinal drainage is achieved through curb stones along both sides of highway pavements. The engineering standard in West Africa is the French Standard, which specifies fixed curb stone design types as Type A, Type T, Type C, Type S, Type P, and Type I. Market research revealed that prefabrication plants in former French territories (including Côte d'Ivoire) all adhere to the French Standard for curb stone mold design. Considering the functionality, aesthetics, and cost-effectiveness of the curb stones, the Chinese designers optimized the curb stone structure dimensions. Because local processing of curb stone molds was limited, and the prefabrication plant lacked a production line for this type of curb stone, the Chinese contractor had to design, manufacture, and put into operation the molds independently.

[0003] In existing technologies, curbstone molds mostly adopt an integrated design or a complex multi-part assembly method, which has problems such as high manufacturing cost, inconvenient mold combination adjustment, and limited service life.

[0004] The purpose of this invention is to provide a prefabricated curbstone mold device to solve the problems mentioned in the background art. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a prefabricated curbstone mold device, including a first frame and a second frame and a locking component. The first frame and the second frame are both L-shaped steel plates. The first frame and the second frame are combined to form a rectangle. The inside of the first frame is welded with a base plate according to the shape of the curbstone. The first frame and the second frame are connected and fixed by the locking component.

[0006] The locking components include fastener one and fastener two. The corners where the top ends of frame one and frame two meet are locked and fixed by fastener one. An extension plate is vertically welded at the connection between frame one and frame two. The two extension plates are locked and fixed by fastener two.

[0007] The fastener includes clamping block one, clamping block two, and adjusting component. Clamping block one and clamping block two are respectively set on the inner and outer sides of the included angle of frame one and frame two, and the adjusting component controls clamping block one and clamping block two to clamp and fix frame one and frame two.

[0008] The second fixing component includes a locking rod and a locking block. The locking rod is installed on the extension plate of the first frame. The extension plate of the frame has a locking hole. The locking block is rotatably installed on the side of the extension plate near the locking hole. After the locking rod passes through the locking hole, it extends out to form the locking block. Rotating the locking block cooperates with the locking rod to lock and fix it. Through the cooperation of the first and second fixing components, the mold can be quickly adjusted and fixed, ensuring the stability and accuracy of the mold during use and improving product quality.

[0009] As a further improvement of this utility model, the steel plates on both sides of the second frame are of different heights, and the height difference between the two is the distance between the lowest side of the bottom plate and the ground. The steel plate on the lower side sits on the top surface of the lowest end of the bottom plate, and the steel plate and the bottom plate are respectively provided with a through hole one and a lock hole two. The lock rod passes through the lock hole two and is connected and fixed to the lock block. The other side is pressed against the end of the bottom plate away from the second frame. This design facilitates the assembly of the first frame and the second frame and improves the compatibility of the first frame and the second frame.

[0010] As a further improvement of this utility model, the adjusting component includes a positioning block one, a positioning block two, a threaded rod, and a locking head. Positioning block one and positioning block two are respectively fixedly installed on the top of clamping block one and clamping block two. Positioning block one is provided with a waist groove. The threaded rod passes through the waist groove and is fixedly connected to positioning block two. The locking head is threadedly connected to the threaded rod and is used to lock clamping block one and clamping block two. This design facilitates the control of clamping block one and clamping block two to quickly clamp and lock the angle between frame one and frame two, correct the position of frame one and frame two, and prevent displacement.

[0011] As a further improvement of this utility model, the frame one is provided with multiple baffles, which are distributed at two angles to the top of the frame two. The baffles are used to support the clamping block two. The baffles can provide a support position for the clamping block two and also prevent the poured concrete from contacting the clamping block two.

[0012] As a further improvement of this utility model, the locking rod includes a rod body, a limiting post, and a rotating handle. A through hole two is provided on the extension plate of the second frame. The rotating handle is rotatably installed in the through hole one or the through hole two. One end of the rod body is provided with a threaded part, which is connected to the inside of the rotating handle through the threaded part. The limiting post is symmetrically installed on the outer wall of the other end of the rod body. The limiting post is used to limit and lock the locking block. The rotating handle is provided to facilitate the control of the rod body to drive the limiting post to move in and out, thereby locking the locking block.

[0013] As a further improvement of this utility model, a limiting ring is provided on the outer wall of the end of the rotating handle, and an annular groove matching the limiting ring is provided in either through hole one or through hole two. The limiting ring limits the rotating handle to move back and forth in through hole one or through hole two. This design makes it easy to restrict the rotating handle, thereby controlling the extension and retraction of the locking rod.

[0014] As a further improvement of this utility model, the center of the locking block is provided with a through groove that passes through the rod and the limiting post. The outer wall of the locking block is provided with a limiting groove. The limiting groove and the through groove are set perpendicular to each other. After the rod and the limiting post pass through the through groove, the locking block is rotated to control the rod and the limiting groove to lock. The designed limiting groove makes it easy for the locking block to lock and unlock when the rotating handle controls the rod to move the limiting post to extend and retract.

[0015] As a further improvement of this utility model, the second frame is provided with a positioning groove on the top surface of one end of the base plate. The width of the positioning groove is the same as the width of the second frame. This design facilitates the quick positioning of the second frame when it is connected to the first frame, and can improve the fit between the frame and the base plate, preventing concrete leakage during concrete pouring.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model uses two L-shaped steel plates as the main components, simplifying the mold structure and reducing manufacturing costs. Through the cooperation of fixing parts one and two, rapid adjustment and fixation of the mold are achieved, ensuring the stability and accuracy of the mold during use, improving product quality. The modular design facilitates maintenance and component replacement, reducing long-term operating costs. Attached Figure Description

[0028] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings. Example 1

[0031] Please see Figure 1-9 This utility model provides a prefabricated curbstone mold device, including a frame 1 and a frame 2 and a locking component. The frame 1 and the frame 2 are both shaped steel plates. The frame 1 and the frame 2 are combined to form a rectangle. The frame 1 has a base plate 3 welded inside according to the shape of the curbstone. The frame 1 and the frame 2 are connected and fixed by the locking component.

[0032] The locking components include fastener 5 and fastener 6. The corners where the top ends of frame 1 and frame 2 are joined are locked and fixed by fastener 5. Extension plates 4 are vertically welded at the joints between frame 1 and frame 2. The two extension plates 4 are locked and fixed by fastener 6.

[0033] The fastener 5 includes clamping block 1 51, clamping block 2 52 and adjusting component. Clamping block 1 51 and clamping block 2 52 are respectively set on the inner and outer sides of the included angle between frame 1 and frame 2, and the adjusting component controls clamping block 1 51 and clamping block 2 52 to clamp and fix frame 1 and frame 2.

[0034] The second fixing component 6 includes a locking rod 61 and a locking block 62. The locking rod 61 is installed on the extension plate 4 of the frame 1. The frame extension plate 4 has a locking hole 7. The locking block 62 is rotatably installed on the side of the extension plate 4 near the locking hole 7. After the locking rod 61 passes through the locking hole 7, the locking block 62 extends out. The locking block 62 is rotated to cooperate with the locking rod 61 to lock and fix it.

[0035] The steel plates on both sides of frame 2 are at different heights. The difference in height between them is the distance between the lowest side of the base plate 3 and the ground. The lower steel plate sits on the top surface of the lowest end of the base plate 3. The steel plate and the base plate 3 are respectively provided with a through hole 1 and a lock hole 2 8. The locking rod 61 passes through the lock hole 2 8 and is connected and fixed to the locking block 62. The other side is pressed against the end of the base plate 3 away from frame 2 2.

[0036] In use, the steel plate on the lower side of frame 2 is placed on the top surface of the lowest end of the base plate 3, and the locking rod 61 on frame 2 is passed through the through hole 1 on the extension plate 4 of frame 1. Then, the clamping block 51 in the fixing part 5 is clamped on the outside of the angle between frame 1 and frame 2, and the clamping block 52 is placed on the inside of the angle. Then, the clamping block 51 and clamping block 52 are controlled by the adjusting part to clamp and fix frame 1 and frame 2, so that the clamping surface of clamping block 51 is completely in contact with the outside of the angle, so that frame 1 and frame 2 can be quickly assembled and fixed. After the angles of frame 1 and frame 2 are clamped, frame 1 and frame 2 are combined into a rectangle. Finally, the locking block 62 and the matching locking rod 61 are further connected and locked to the vertical extension plate 4 of frame 1 and frame 2, increasing the overall stability of the mold. Example 2

[0037] Please see Figure 1-3 The adjusting component includes a positioning block 53, a positioning block 54, a threaded rod 55, and a locking head 56. The positioning block 53 and the positioning block 54 are respectively fixedly installed on the top of the clamping block 51 and the clamping block 52. The positioning block 53 is provided with a waist groove. The threaded rod 55 passes through the waist groove and is fixedly connected to the positioning block 54. The locking head 56 is threadedly connected to the threaded rod 55 and is used to lock and fix the clamping block 51 and the clamping block 52.

[0038] The frame 1 is provided with multiple baffles 11, which are distributed at two angles to the top of the frame 2. The baffles 11 are used to support the clamping block 52.

[0039] In use, after clamping blocks 51 and 52 are installed on the inner and outer sides of the included angle between frame 1 and frame 2, threaded rod 55 passes through positioning block 53, and locking head 56 is threadedly connected to threaded rod 55. Rotate locking head 56 until locking head 56 presses clamping block 51 connected to positioning block 53 and clamps it completely with the outer side of the included angle. This completes the quick locking of clamping blocks 51 and 52 at the included angle of the top of frame 1 and frame 2, preventing frame 1 and frame 2 from tilting during assembly, which would affect curbstone production. This helps improve the overall stability of the mold and the quality of precast curbstone. In this embodiment, baffle 11 is set at the included angle between frame 1 and frame 2 to provide support for clamping block 51. It also prevents concrete from contacting clamping block 52 when pouring curbstone model, avoiding adhesion to curbstone model. This not only prevents interference with curbstone production but also increases the reusability of fixing component 5 and reduces resource waste. Example 3

[0040] Please see Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The locking rod 61 includes a rod body 611, a limiting post 612, and a rotating handle 613. The extension plate 4 of the frame 2 has a through hole 2. The rotating handle 613 is rotatably installed in the through hole 1 or through hole 2. One end of the rod body 611 has a threaded part, which is threadedly connected to the inside of the rotating handle 613. The limiting post 612 is symmetrically installed on the outer wall of the other end of the rod body 611, and is limited and locked by the limiting post 612 and the locking block 62.

[0041] A limiting ring 614 is provided on the outer wall of the end of the rotating handle. An annular groove matching the limiting ring 614 is provided in either through hole one or through hole two. The limiting ring 614 limits the rotating handle 613 to move back and forth in through hole one or through hole two.

[0042] The locking block 62 has a through groove 621 at its center that passes through the rod 611 and the limiting post 612. The outer wall of the locking block 62 has a limiting groove 622. The limiting groove 622 and the through groove 621 are perpendicular to each other. After the rod 611 and the limiting post 612 pass through the through groove 621, rotating the locking block 62 controls the rod 611 to be limited and locked with the limiting groove 622 by rotating the handle 613.

[0043] In use, after the screw rod 611 on frame 2 extends through the through hole 1 on the extension plate 4 of frame 1 to extend the locking block 62, rotate the locking block 62 90 degrees so that the limiting groove 622 on the locking block 62 is aligned with the upper limit post 612 of the locking rod 61. Then rotate the rotating handle. Since the rotating handle 613 is restricted on frame 2, it can only rotate within the through hole 1 of frame 2. The locking rod 61 is threadedly connected to the rotating handle 613. When the rotating handle 613 rotates, it drives the locking rod 61 to extend and retract, thereby driving the limiting post 612 into the limiting groove 622 of the locking block 62, locking and fixing the locking block 62, preventing the locking block 62 from rotating, and thus further locking frame 1 and frame 2. Repeat the above operation at the lowest end of the base plate 3 where it connects to frame 2 to complete the locking. The operation is simple and quick, and it is convenient for mold assembly and fixing.

[0044] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
