Description

Technical Field

[0001] This utility model relates to the field of precast reinforced concrete pile mold technology, and more specifically, to a prestressed concrete flat pile mold. Background Technology

[0002] Prestressed concrete flat plate piles are concrete piles that are prefabricated, cured to their design strength, and then transported to the construction site for driving. The manufacturing process includes prefabrication and curing at a prefabrication plant until the pile reaches its design strength, followed by driving it into the ground using a piling machine. Then, the foundation beam is poured on top of the pile. During the prefabrication of concrete flat plate piles, a reinforcing cage is placed into a mold, and concrete is poured into the mold to form the flat plate pile. However, existing flat plate pile molds are not easy to remove after the flat plate pile has solidified, especially when the flat plate pile has grooves on its side, making demolding difficult. Therefore, we propose a prestressed concrete flat plate pile mold. Utility Model Content

[0003] In view of the problems mentioned in the background art above, the purpose of this utility model is to provide a prestressed concrete flat plate pile mold.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A prestressed concrete flat pile mold includes a bottom mold, a top mold, and a rotating mold. The bottom mold consists of a bottom template, multiple bottom longitudinal reinforcement plates, a lower side mold, multiple bottom transverse reinforcement plates, two triangular steel bars, two lower reinforcing bars, and two bottom mold closing strips. The top mold consists of an upper side mold, multiple top transverse reinforcement plates, multiple top longitudinal reinforcement plates, multiple sets of guide plates, two upper reinforcing bars, and two top mold closing strips. The rotating mold consists of multiple sets of rotating frames, multiple hinge pins, multiple ear plates, a rotating plate, a top sealing plate, multiple triangular support plates, and a closed side mold. Multiple sets of mounting holes are provided on both the top mold closing strip and the bottom mold closing strip. Connecting mechanisms are fitted into these mounting holes. The multiple bottom longitudinal reinforcement plates are fixedly connected to the bottom of the bottom template, and the lower side mold is fixedly connected to one side of the bottom template. The bottom mold horizontal stiffener is fixedly sleeved on the outside of the bottom mold template, the bottom mold longitudinal stiffener, and the lower mold. Two triangular steel bars are fixedly connected to both sides of the top surface of the bottom mold template. Multiple cover mold horizontal stiffeners are fixedly sleeved on the outside of the upper mold. Multiple cover mold longitudinal stiffeners are fixedly sleeved on multiple cover mold horizontal stiffeners. Multiple sets of guide plates are fixedly sleeved between two adjacent cover mold horizontal stiffeners. Multiple rotating frames are fixedly connected to the side of a bottom mold longitudinal stiffener. Multiple hinge pins are fixedly sleeved on multiple rotating frames. Multiple ear plates are rotatably connected to multiple hinge pins. The rotating plate is fixedly connected to the top of multiple ear plates. The closed side mold is fixedly connected to one side of the rotating plate. The top sealing plate is fixedly connected to the other side of the top of the rotating plate. Multiple triangular support plates are fixedly connected between the top sealing plate and the rotating plate.

[0006] As a preferred embodiment of this utility model, the connecting mechanism includes a mold clamping bolt sleeved on a set of mounting holes, a fastening nut threaded onto the top of the mold clamping bolt, two bottom mold clamping strips fixedly connected to the top of multiple bottom mold horizontal ribs, and two top mold clamping strips fixedly connected to the bottom of multiple top mold horizontal ribs.

[0007] As a preferred embodiment of this utility model, the top of the bottom mold cross stiffener is provided with a lower movable groove, and the bottom of the top mold cross stiffener is provided with an upper movable groove.

[0008] As a preferred embodiment of this utility model, each of the plurality of bottom mold horizontal rib plates has two bottom mold lifting holes, and each of the plurality of top mold horizontal rib plates has two top mold lifting holes.

[0009] As a preferred embodiment of this utility model, the two lower reinforcing strips are fixedly sleeved on multiple bottom mold cross ribs, and the side portions of the two lower reinforcing strips are respectively connected to the top and bottom of the outer side of the lower mold.

[0010] As a preferred embodiment of this utility model, the two upper reinforcing strips are fixedly connected to multiple cover mold cross ribs, and the side portions of the two upper reinforcing strips are respectively connected to the top and bottom of the outer side of the upper mold.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: In this utility model, after the bottom mold and the top mold are closed, the mold cavity is formed by the closed side mold, the bottom template, the lower side mold, the upper side mold, and the steel plates connected to both ends of the reinforcing cage. Concrete is poured into the mold cavity from the inside of the guide plate. This mold can cast and shape the flat plate pile. When demolding, the top mold is removed from above the bottom mold, and the rotating plate is turned to make the rotating plate and the closed side mold rotate outward around the hinge pin axis, so that the side of the closed side mold moves out of the groove on the side of the formed flat plate pile. Then the formed flat plate pile is taken out of the bottom mold. This design avoids the demolding difficulty caused by the groove on the side of the flat plate pile, and is highly efficient and practical. Attached Figure Description

Multiple rotating frames 27 are fixedly connected to the side of a bottom template longitudinal stiffener 5. Multiple hinge pins 28 are fixedly sleeved on the multiple rotating frames 27. Multiple ear plates 7 are rotatably connected to the multiple hinge pins 28. A rotating plate 8 is fixedly connected to the top of the multiple ear plates 7. A closed side template 11 is fixedly connected to one side of the rotating plate 8. A top sealing plate 9 is fixedly connected to the other side of the top of the rotating plate 8. Multiple triangular support plates 10 are fixedly connected between the top sealing plate 9 and the rotating plate 8.

[0022] In this embodiment, the ear plate 7 has a thickness of 7 mm and is precisely laser-cut; the rotating plate 8 has a thickness of 20 mm; the closed side mold 11 has a thickness of 5 mm and is formed by bending; the top sealing plate 9 has a thickness of 10 mm; and the triangular support plate 10 has a thickness of 6 mm. The ear plate 7, rotating plate 8, top sealing plate 9, triangular support plate 10, and closed side mold 11 are welded together. The triangular steel strip 17 on one side of the top surface of the bottom template 3 is in contact with the inner bottom end of the closed side mold 11, and the triangular steel strip 17 on the other side of the top surface of the bottom template 3 is in contact with the lower side. The bottom inner side of mold 16 fits together, and triangular steel strip 17 is used to prevent concrete leakage. In addition, the height of the rotating plate 8 after it is vertical is consistent with the height of the top of the upper mold 4. When pouring concrete, the pouring is stopped when the height of the concrete is level with the height of the top of the rotating plate 8. In addition, the lengths of the bottom mold 3, upper mold 4, bottom mold longitudinal reinforcement plate 5, rotating plate 8, top sealing plate 9, closed side mold 11, cover mold longitudinal reinforcement plate 13, lower mold 16, triangular steel strip 17, lower reinforcing strip 20, upper reinforcing strip 21, cover mold closing strip 22, and bottom mold closing strip 23 are all consistent with the required forming length of the flat plate pile. The mold is long and narrow.

[0023] For details, please refer to Figure 1 , Figure 2 and Figure 4 The connecting mechanism 15 includes a mold clamping bolt 25 sleeved on a set of mounting holes 24, and a fastening nut 26 threaded on the top of the mold clamping bolt 25. Two bottom mold clamping strips 23 are fixedly connected to the top of multiple bottom mold horizontal stiffening plates 6, and two cover mold clamping strips 22 are fixedly connected to the bottom of multiple cover mold horizontal stiffening plates 12.

[0024] In this embodiment, the bottom mold 1 and the top mold 2 are fixed together by the cooperation of the cover mold clamping strip 22, the bottom mold clamping strip 23, the mounting hole 24, the clamping bolt 25, and the fastening nut 26. At the same time, the mounting hole 24 on the cover mold clamping strip 22 and the mounting hole 24 on the bottom mold clamping strip 23 are vertically aligned so that the clamping bolt 25 can be inserted into the mounting hole 24 on the cover mold clamping strip 22 and the bottom mold clamping strip 23. In addition, the outer diameter of the clamping bolt 25 and the inner diameter of the mounting hole 24 are equal to ensure the stability of the connection between the bottom mold 1 and the top mold 2 by the clamping bolt 25 and the fastening nut 26.

[0025] For details, please refer to Figure 1 The bottom mold horizontal stiffener plate 6 is provided with a lower movable groove 31 at the top, and the top mold horizontal stiffener plate 12 is provided with an upper movable groove 30 at the bottom.

[0026] In this embodiment, the lower movable groove 31 and the upper movable groove 30 facilitate the rotation of the rotating plate 8, so that the side of the closed side mold 11 can be separated from the side of the formed flat plate pile. In addition, when the bottom mold 1 and the cover mold 2 are closed, the top of the upper movable groove 30 can limit the top sealing plate 9 of the rotating plate 8, ensuring that the rotating plate 8 is fixed in a vertical state. Thus, the closed side mold 11, the bottom mold 3, the lower side mold 16, the upper side mold 4, and the steel plates connected at both ends of the reinforcing cage form a cavity for the pouring of the flat plate pile. The shape of the steel plates connected at both ends of the reinforcing cage is consistent with the shape of the inner cavity formed by the closed side mold 11, the bottom mold 3, the lower mold 16, and the upper mold 4.

[0027] For details, please refer to Figure 1 Two bottom mold lifting holes 18 are provided on each of the multiple bottom mold horizontal stiffening plates 6, and two cover mold lifting holes 19 are provided on each of the multiple cover mold horizontal stiffening plates 12.

[0028] In this embodiment, the bottom mold 1 is hoisted through the bottom mold hoisting hole 18, and the top mold 2 is hoisted through the top mold hoisting hole 19.

[0029] For details, please refer to Figure 1 and Figure 2 Two lower reinforcing strips 20 are fixedly sleeved on multiple bottom mold horizontal stiffener plates 6, and the side parts of the two lower reinforcing strips 20 are respectively connected to the top and bottom of the outer side of the lower mold 16.

[0030] In this embodiment, the lower reinforcing strip 20 provides reinforcement support to the side of the lower mold 16.

[0031] For details, please refer to Figure 1 and Figure 2 Two upper reinforcing strips 21 are fixedly connected to multiple cover mold cross ribs 12, and the side parts of the two upper reinforcing strips 21 are respectively connected to the top and bottom of the outer side of the upper mold 4.

[0032] In this embodiment, the upper reinforcing strip 21 provides reinforcement support to the side of the upper mold 4.

[0033] Working principle: During use, first clean the inner walls of the mold, specifically the inner surfaces of the closed side mold 11, bottom mold 3, lower mold 16, and upper mold 4. Then, spray a release agent onto the inner surfaces of these molds to prevent sticking. Next, place the reinforcing cage of the concrete sheet pile into the lower cavity of the mold composed of the closed side mold 11, bottom mold 3, and lower mold 16. Steel plates are connected to both ends of the reinforcing cage, used to seal both ends of the sheet pile mold. The end faces of the steel plates are provided with screw holes for subsequent connection and installation of the formed sheet pile. Furthermore, the outer end face of the sealing plate is flush with both ends of the bottom mold 3, closed side mold 11, lower mold 16, and upper mold 4. Rotate... Rotating plate 8 causes the closed side mold 11 to close to the closed position, and the cover mold 2 is placed above the bottom mold 1. At this time, the mounting holes 24 on the cover mold closing strip 22 and the mounting holes 24 on the bottom mold closing strip 23 are aligned. The bottom mold 1 and the cover mold 2 are fixed by the closing bolts 25 and the fastening nuts 26. At this time, the side of the steel plate at the end of the reinforcing cage is in contact with the inner side of the bottom template 3, the closed side mold 11, the lower side mold 16 and the upper side mold 4. Finally, concrete is poured into the mold from the inside of the guide plate 14. When the height of the concrete is level with the top surface of the rotating plate 8, the pouring is stopped and the mold is placed in the steam curing pit for curing. The product can reach the design strength in about 5 to 6 hours of curing time. At this time, the mold is lifted out of the curing tank.

[0034] When disassembling the mold, first remove the mold clamping bolts 25 and fastening nuts 26 from the mold clamping strips 22 and 23 of the cover mold and bottom mold. Then, turn the rotating plate 8 to make the rotating plate 8 and the closed side mold 11 rotate outward around the hinge pin 28, so that the side of the closed side mold 11 moves out of the groove on the side of the formed flat plate pile. Finally, the formed flat plate pile can be taken out from the bottom mold 1.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
