[0046] A partition plate 2 is symmetrically installed on the top of the parting surface of the square pile mold 1 to form a profile on the upper surface of the formed support pile;

[0047] Separation components 3 are respectively installed at the two top corners of the parting surface of the square pile mold 1 to form a concave-convex structure for splicing on both sides of the formed support pile;

[0048] The square pile mold 1 comprises an upper mold body 11 and a lower mold body 12. The upper mold body 11 and the lower mold body 12 are fixedly connected by a locking assembly 4 after the mold is closed. The locking assembly 4 is an ear-hanging locking bolt assembly. The contact surface between the upper mold body 11 and the lower mold body 12 is a parting surface, and the interior thereof is a molding cavity.

[0049] The molding cavity of the square pile mold 1 is a quadrilateral, and the two adjacent sides of the quadrilateral are right angles; the cross section of the mold is square when the mold is closed. This design helps to improve the strength and stability of the mold, reduce mold loss, reduce production costs, and improve economic benefits;

[0050] in,

[0051] The partition 2 has a triangular cross section and is formed by a die-casting machine to form a straight surface on the upper surface of the formed support pile. The partition 2 is a solid structure or a hollow structure, and includes two right-angled surfaces 21 and an inclined surface 22. The inclined surface 22 is arranged toward the inner cavity of the square pile mold 1 and contacts the inner cavity of the square pile mold 1.

[0052] The two groups of partition components 3 are arranged 180 degrees apart from each other, and include a partition body 31 and a rib 32. The partition body 31 is embedded in the top corner of the inner cavity of the square pile mold 1. The rib 32 extends outward from the center of the upper surface of the partition body 31. A male tenon and a female tenon are symmetrically arranged on the upper surface of the partition body 31 on both sides of the rib 32.

[0053] The working principle and beneficial effects of the above embodiments are as follows:

[0054] The present invention adopts unused steel molds to be welded and assembled into a mold with a square cross-section. When in use, the steel cage is first placed in the lower mold body 12, and the concrete is evenly filled in the lower mold body 12 along the mold, and then the upper mold body 11 is hung above the lower mold body 12, and the upper and lower mold halves are fixed by the locking component 4. After prestressing, the mold is hung on the centrifuge for rotation and molding; the setting of the partition 2 diversifies the profile of the upper surface of the supporting pile, and the partition component 3 enables the mold to radially mold two separate supporting piles or mold a single supporting pile with a concave-convex structure, and the production efficiency is high.

[0055] The partition 2 and the partition component 3 are detachably connected to the square pile mold 1. Different specifications and shapes of the partition 2 and the partition component 3 can be replaced according to production needs to meet the diverse production needs of support piles and improve the utilization efficiency of the mold.

[0056] The partition 2 is designed to be solid or hollow according to the cross-sectional size and structural strength requirements of the mold, and the most economically efficient arrangement is selected;

[0057] The partition assembly 3 of this embodiment is used to form two separate support piles. The partition plate 2 is a triangular partition plate, which can produce support piles with a flat upper surface to form a flat retaining structure.

[0058] Embodiment 2:

[0060] Different from the cross-sectional shape of the partition in the first embodiment, the partition 2 is an arc-shaped partition, which can produce support piles with an arc surface on the upper surface. The arc surface can adapt to a specific curvature, so that the molding mold can produce support piles with an aesthetic appearance.

[0061] Embodiment three:

[0062] The rest is the same as the first embodiment, except that a protrusion 5 is provided on each side of the inner cavity of the square pile mold 1, and there are no less than two protrusions 5 on a single side, and the cross-sectional shape of the protrusion 5 is one of the following: arc, rectangle, trapezoid.

[0063] The setting of the protrusion 5 can form a specific shape on the edge of the supporting pile, such as an arc, rectangle or trapezoid, so that the edge of the formed supporting pile is also smooth, regular or gradually changing. The design of the protrusion 5 further increases the bearing surface of the supporting pile and enhances the structural performance of the supporting pile.

[0064] Embodiment 4:

[0065] The rest is the same as the first embodiment, except that the partition assembly 3 includes a groove partition 33 and a protrusion partition 34, the groove partition 33 is installed at one vertex of the parting surface of the square pile mold 1, and the protrusion partition 34 is installed at another vertex of the parting surface of the square pile mold 1;

[0066] A groove is provided in the middle of the upper surface of the groove partition plate 33 , and a protrusion is extended outward from the middle of the upper surface of the protrusion partition plate 34 , and the protrusion matches the groove.

[0067] The partition assembly 3 of this embodiment is used to form a single supporting pile. The groove partition 33 and the raised partition 34 form a specific concave-convex structure on both sides of the supporting pile, which is used for connecting the supporting piles and improving the structural stability of the supporting piles.

[0068] In one embodiment,

[0069] The width of the rib 32 gradually decreases from the side close to the partition body 31 to the side away from the partition body 31;

[0070] The width of the ribs 32 of this embodiment gradually decreases to form a certain demoulding slope, which facilitates the molding and demoulding of the supporting piles.

[0071] In one embodiment,

[0072] The cross section of the male tenon or female tenon is any one of arc, rectangle, trapezoid, ellipse, dovetail, drum, and waist shape, and the cross section of the groove and the protrusion is any one of arc, rectangle, trapezoid, ellipse, dovetail, drum, and waist shape;

[0073] The diversification of the splicing and mosaic structures of the supporting piles makes the assembly of the supporting piles more flexible and improves the functionality of the supporting piles.

[0074] In one embodiment,

[0075] A plurality of running wheels 6 are provided on the upper mold body 11 and the lower mold body 12 to rotate the mold on the centrifuge, and a crane hanging ear for hoisting is provided on the outside of the upper mold body 11 and the lower mold body 12;

[0076] A plurality of running wheels 6 are evenly mounted on the upper half mold body 11 and the lower half mold body 12, which help to evenly distribute the concrete in the inner cavity of the mold during the centrifugal molding process, thereby improving the quality and consistency of the molded support piles;

[0077] The crane hanging ears can be conveniently used to use a crane to hang the upper half mold body 11 (lower half mold body 12) or the entire mold for transfer using a hanging rope.

[0078] In summary:

[0079] The forming mold of a concrete supporting pile of the present invention has a simple splicing assembly and a fast pile supply speed, which can meet the needs of the construction progress. The setting of the partition diversifies the profile of the upper surface of the supporting pile. The partition assembly enables the mold to form two separate supporting piles in the radial direction or to form a single supporting pile and form a concave-convex structure with a spliced ​​and embedded pile body, which can reduce the materials used for pile formation, increase the bearing surface of the supporting pile, and enhance the pull-out and compression resistance of the pile body.

[0080] The partitions and partition components are detachably connected to the square pile mold. Different specifications and shapes of the partitions and partition components can be replaced according to production needs to meet the diverse production needs of support piles and improve the utilization efficiency of the mold;

[0081] The design of the protrusions further increases the bearing surface of the supporting piles, which has the advantages of saving materials, light weight and enhancing its structural performance.
