Description

Technical Field

[0001] This utility model relates to the technical field of equipment for pile foundation construction, and in particular to an arched sheet pile production mold based on the modification of a hollow square pile mold. Background Technology

[0002] There are many types of concrete piles, and the pile type has a significant impact on the mechanical properties of concrete piles. U-shaped sheet piles (also known as Z-shaped sheet piles) are one type of concrete pile. A U-shaped sheet pile consists of a pile body, a top, two downward-sloping waist sections located on either side of the top, and lower flanges located at the bottom of the two waist sections and extending horizontally outwards. Due to its good mechanical properties and ease of manufacturing, U-shaped sheet piles are increasingly widely used. However, U-shaped sheet piles also have certain drawbacks. For example, the lower flanges are relatively small, and the trapezoidal positive grooves result in a smaller thickness at the top. This limits the area available for reinforcement in the waist and top sections, leading to some deficiencies in the overall strength and mechanical properties of the pile.

[0003] To address the aforementioned issues, existing technologies have developed arched concrete piles, as illustrated in Chinese Utility Model Patent Application No. CN202322433300.6 (Authorization Announcement No. CN220953350U). Arched concrete piles are an improvement upon the traditional U-shaped sheet pile. The pile body has a top surface, inclined surface, side surface, bottom surface, and arched surface. The arched surface forms an arched groove extending along the length of the pile body. Compared to the traditional trapezoidal groove, the entire groove has an arc transition, which can enhance the overall strength of the sheet pile and especially solve the problem of stress concentration and cracking at the fold line position inside the U-shaped sheet pile.

[0004] Currently, the widespread use of arched sheet piles has led many manufacturers to require new production molds, increasing their production costs. Furthermore, the application of hollow square piles in existing concrete piles is gradually decreasing, leaving manufacturers with many idle production molds intended for hollow square piles, thus wasting production resources. Therefore, further improvements are needed to the production molds for arched sheet piles. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an arched sheet pile production mold with a reasonable structure and cost-saving capability in view of the above-mentioned existing technology, and the arched sheet pile production mold is based on the modification of the hollow square pile mold.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: An arched sheet pile production mold based on the modification of a hollow square pile mold includes an upper mold and a lower mold, wherein the upper mold and the lower mold are joined to form a rectangular mold cavity. Its characteristic is that it further includes...

[0007] A partition is provided between the upper mold and the lower mold. The left and right ends of the partition are installed at the connection between the upper mold and the lower mold. The partition divides the rectangular mold cavity into two symmetrically arranged first mold cavity and second mold cavity along the diagonal. The partition is used to form the bottom surface of the arched sheet pile.

[0008] The inserts are respectively set at the right angle of the first mold cavity and the second mold cavity. The inserts are fixed on the inner wall of the upper mold or the lower mold and are used to form the top surface of the arched sheet pile.

[0009] Furthermore, dovetail blocks are provided at both ends of the partition plate, and grooves are provided on opposite sides of the upper and lower molds. When the upper and lower molds are closed, the two grooves can form a dovetail groove for the dovetail blocks to be installed. The partition plate is installed between the upper and lower molds by means of the cooperation of the dovetail blocks and the dovetail groove. The dovetail blocks are first placed in the groove of the upper or lower mold. After the upper and lower molds are closed, the dovetail blocks are installed in the dovetail grooves, so that the partition plate is stably connected to the upper and lower molds. When the upper and lower molds are in centrifugal forming motion, the partition plate will not come out from between the upper and lower molds, ensuring that the partition plate can move with the upper and lower molds in centrifugal motion.

[0010] Furthermore, the partition plate is also provided with two blocks extending vertically. These blocks are spaced apart from the dovetail blocks. The upper end of each block abuts against the inner wall of the upper mold, and the lower end abuts against the inner wall of the lower mold. These blocks are used to form the side of the arched sheet pile. While these blocks are used to form the side of the arched sheet pile, some hollow square pile molds also have vertically extending baffles at the joints, which can also be used to form the side of the arched sheet pile.

[0011] Furthermore, the insert has two connecting surfaces and one forming surface. The connecting surfaces are welded or snapped onto the inner wall of the upper or lower mold, and the forming surface is arranged parallel to the partition plate. The forming surface is used to form the top surface of the arched sheet pile. Since the top and bottom surfaces of the arched sheet pile are parallel, the forming surface of the insert is parallel to the partition plate, ensuring that the production mold can manufacture arched sheet piles that meet the requirements.

[0012] Furthermore, the cross-section of the insert is a right-angled triangle. This design increases the contact area between the insert and the upper or lower mold, resulting in a more stable fixation effect between the insert and the upper or lower mold.

[0013] Furthermore, the insert includes a main body and a mounting block. The two connecting surfaces are disposed on the main body, and the forming surface is disposed on the mounting block. The mounting block is detachably connected to the main body. The main body is used to fix itself inside the upper or lower mold, and the mounting block can be detachably mounted on the main body to adjust the production mold to produce arched sheet piles with different top surface dimensions.

[0014] Furthermore, there are multiple mounting blocks, which are stacked and installed sequentially. The top surface dimensions of the arched sheet pile include the distance between the top and bottom surfaces and the width of the top surface. Stacking multiple mounting blocks allows the production mold to be adjusted to produce arched sheet piles with different top surface dimensions, thus broadening the applicability of the production mold.

[0015] Compared with the prior art, the advantages of this utility model are as follows: The upper and lower molds of the production mold of this application, which form a rectangular mold cavity, were originally used for producing hollow square piles. This application modifies the upper and lower molds to enable the production of arched sheet piles. Specifically, a partition divides the rectangular mold cavity into a first mold cavity and a second mold cavity, which are respectively used to form arched sheet piles. The partition is used to form the bottom surface of the arched sheet pile, the insert is used to form the top surface of the arched sheet pile, and the inner walls of the upper and lower molds are used to form the inclined surface of the arched sheet pile. Furthermore, the modified production mold also uses a centrifugal forming method, thereby enabling the production mold to form the arched surface of the arched sheet pile. Therefore, the arched sheet pile production mold based on the modification of the hollow square pile mold has a reasonable structure and can produce arched sheet piles, thereby reducing the production cost of manufacturers and improving the utilization rate of the hollow square pile production mold.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-7 The image shown is the preferred embodiment of this utility model.

[0025] The production mold in this embodiment was originally used for producing hollow square piles, such as... Figure 4 As shown, the mold includes an upper mold 1 and a lower mold 2. The upper mold 1 and the lower mold 2 are closed to form a rectangular mold cavity. The mold cavity of this application is square. The mold is formed by centrifugal molding, thereby producing hollow square piles.

[0026] like Figure 1 and Figure 2 As shown, this embodiment improves upon the existing mold, further including a partition plate 3 and an insert 4. The partition plate 3 is positioned between the upper mold 1 and the lower mold 2, with its left and right ends installed at the connection points of the upper mold 1 and the lower mold 2. The partition plate 3 divides the rectangular mold cavity diagonally into two symmetrically arranged isosceles right triangles: a first mold cavity 11 and a second mold cavity 21. The partition plate 3 is used to form the bottom and side surfaces of the arched sheet pile. Wherein, as... Figure 3 and Figure 5 As shown, in this embodiment, the partition plate 3 has dovetail blocks 31 at both its left and right ends. Grooves are provided on opposite sides of the upper mold 1 and lower mold 2. When the upper mold 1 and lower mold 2 are closed, the two grooves form a dovetail groove 5 for the dovetail blocks 31 to be installed. The partition plate 3 is installed between the upper mold 1 and lower mold 2 by means of the cooperation of the dovetail blocks 31 and the dovetail groove 5, allowing the partition plate 3 to be centrifugally formed together with the upper mold 1 and lower mold 2. Furthermore, the partition plate 3 in this embodiment also has two blocks 32 extending vertically. The blocks 32 are spaced apart from the dovetail blocks 31. The upper end of the blocks 32 abuts against the inner wall of the upper mold 1, and the lower end of the blocks 32 abuts against the inner wall of the lower mold 2. The blocks 32 are used to form the side of the arched sheet pile.

[0027] like Figure 6 and Figure 7 As shown, in this embodiment, there are two inserts 4. The cross-section of each insert 4 is an isosceles right triangle. The two inserts 4 are respectively located at the right angles of the first mold cavity 11 and the second mold cavity 21. The inserts 4 are fixed to the inner wall of the upper mold 1 or the lower mold 2. The inserts 4 are used to form the top surface of the arched sheet pile. In this embodiment, the insert 4 includes a main body 41 and an mounting block 42. The main body 41 has two connecting surfaces 411, which are used to weld or snap onto the inner wall of the upper mold 1 or the lower mold 2. The cross-section of the main body 41 is an isosceles right triangle. The mounting block 42 has a forming surface 421, which is parallel to the partition plate 3. The forming surface 421 is used to form the top surface of the arched sheet pile. The cross-section of the mounting block 42 is trapezoidal. The mounting block 42 is detachably connected to the main body 41. Of course, there can be multiple mounting blocks 42. Multiple mounting blocks 42 are stacked and installed sequentially, and adjusted according to the top surface size of the arched sheet pile. In this embodiment, only one mounting block 42 is shown.

[0028] The workflow of this embodiment is as follows: First, inserts 4 are installed in the upper mold 1 and the lower mold 2 respectively. That is, the right angle of the main body 41 is aligned with the right angle of the first mold cavity 11 and the second mold cavity 21, and the two connecting surfaces 411 of the main body 41 are welded or snapped onto the inner wall of the upper mold 1 or the lower mold 2. Then, the mounting block 42 is installed on the main body 41, thereby completing the assembly of the inserts 4. Next, the dovetail block 31 of the partition plate 3 is placed in the groove of the lower mold 2, so that the lower end of the stop block 32 abuts against the inner wall of the lower mold 2. Then, the upper mold 1 and the lower mold 2 are closed, that is, the dovetail block 31 is installed in the dovetail groove 5, and the upper end of the stop block 32 abuts against the inner wall of the upper mold 1, thereby completing the assembly of the production mold. Finally, the assembled production mold can form two arched sheet piles by centrifugal method.
