[0002] Existing mold devices for producing hollow concrete pipe piles usually include a lower mold base and an upper mold base arranged horizontally. After the lower mold base and the upper mold base are combined, a pipe pile forming cavity is formed. During the production process, concrete slurry is sent to the lower mold base through a feeding pipeline. Subsequently, the lower mold base and the upper mold base are combined, and the lower mold base and the upper mold base are rolled by a rolling device so that after the slurry solidifies, a hollow is formed in the middle of the pipe pile forming cavity. During the production process, the operation and installation of the mold device and the later disassembly to take out the concrete pipe pile are very troublesome, which is not conducive to industrial production.

[0003] On the other hand, in some special application scenarios, special-shaped pipe piles with a non-circular cross-section and a hollow in the middle are required, such as special-shaped pipe piles with an elliptical cross-section or an approximately elliptical cross-section and a hollow in the middle. However, this production method can only produce hollow pipe piles with a circular cross-section and a hollow in the middle. Summary of the Invention

[0027] The present invention will be further described below in conjunction with the drawings and embodiments:

[0028] Please refer to Figures 1 to 5As shown in the figure, this embodiment provides a mold for the production of hollow concrete pipe piles with convenient disassembly and assembly, including a vertical pipe mold assembly 1 arranged in the vertical direction. The vertical pipe mold assembly 1 includes a first split mold 2 and a second split mold 3. Inside the first split mold 2 and the second split mold 3, there are respectively a first split forming cavity and a second split forming cavity for accommodating the slurry. On the sides of the first split mold 2 and the second split mold 3 that are close to each other, there are respectively an insertion arm 22 and an insertion slot 32 that are inserted into each other. The insertion arm 22 and the insertion slot 32 are respectively provided with communication ports for connecting the first split forming cavity and the second split forming cavity. At the lower ends of the first split forming cavity and the second split forming cavity, there are respectively demolding openings 4, and at the upper ends of the first split forming cavity and the second split forming cavity, there are respectively pouring ports 5 for pouring the slurry.

[0029] The communication port includes a first communication port provided on the insertion arm and a second communication port provided on the insertion slot. In this embodiment, the insertion arm 22 is a hollow rectangular structure jointly formed by a first horizontal plate, a first vertical plate, a second horizontal plate, and a second vertical plate. Among them, the first horizontal plate and the second horizontal plate are parallel to each other, the first vertical plate and the second vertical plate are parallel to each other, and a first communication port is enclosed between the first horizontal plate, the second horizontal plate, the first vertical plate, and the second vertical plate. The second communication port is provided at the bottom of the insertion slot.

[0030] The usage method of the above mold includes the following steps:

[0031] S1. Refer to Figure 2 and Figure 6 As shown in the figure, insert the insertion arm 22 and the insertion slot 32 into each other to combine the first split mold 2 and the second split mold 3, and make the combined first split mold 2 and second split mold 3 in a vertical state. After the insertion arm 22 and the insertion slot 32 are inserted into each other, the first split forming cavity and the second split forming cavity are connected through the communication port;

[0032] S2. Pour the slurry into the first split forming cavity and the second split forming cavity through the pouring port 5;

[0033] S3. Refer to Figure 1 and Figure 5 As shown in the figure, after the concrete slurry solidifies and forms, the pipe pile is demolded from the demolding opening 4 at the lower end of the first split forming cavity and the second split forming cavity and exits the vertical pipe mold assembly 1.

[0034] In the present invention, the insertion arm 22 and the insertion slot 32 are used to achieve a quick and detachable connection between the first split die 2 and the second split die 3, and to connect the first split forming cavity and the second split forming cavity inside the first split die 2 and the second split die 3. After the concrete slurry is poured into the first split forming cavity and the second split forming cavity, the concrete slurry in the first split forming cavity and the second split forming cavity can be connected through the communication port, so that after the concrete slurry solidifies, the concrete slurry in the first split forming cavity and the second split forming cavity forms an integral hollow concrete pipe pile. For the horizontal die device in the prior art, a rolling device is required to form a hollow structure. The present invention adopts a vertical pipe die assembly 1 arranged in the vertical direction, and a hollow concrete pipe pile with a hollow can be formed by the mutual cooperation between the first split forming cavity, the second split forming cavity, the insertion arm 22 and the insertion slot 32. The forming method is more convenient, the overall die structure is simpler, and during the production of the hollow pipe pile, the installation and disassembly of the die are more convenient and fast.

[0035] In addition, due to process limitations, the horizontal die device in the prior art can only produce hollow pipe piles with a middle hollow structure having a circular cross-section. The present invention can be used to produce special-shaped pipe piles with a non-circular cross-section in the middle hollow structure. In this embodiment, the cross-section of the middle hollow structure of the pipe pile is a quasi-elliptical structure, and the outer peripheral cross-section of the pipe pile is also a quasi-elliptical structure. If the prior art is adopted, only special-shaped pipe piles with a quasi-elliptical outer peripheral cross-section and a circular cross-section in the middle hollow structure can be produced, which will result in uneven wall thickness of the pipe pile, and it is easier to break at the place with a smaller thickness.

[0036] The above-mentioned quasi-elliptical structure refers to an approximately elliptical shape structure surrounded by two symmetric arc curve segments and two symmetric straight line segments.

[0037] See Figure 2 As shown, in the present invention, the vertical pipe die assembly 1 is a split structure, and the vertical pipe die assembly 1 is composed of a first split die 2 and a second split die 3 that are inserted into each other. The vertical pipe die assembly 1 is divided into two halves. Compared with an integral die, splitting the vertical pipe die assembly 1 can reduce the production equipment scale and production equipment cost of the die itself, and reduce the production cost.

[0038] See Figure 3 and Figure 4 As shown, the insertion arm 22 is provided with an insertion end 221 for extending into the insertion slot 32. The edge of the slot opening of the insertion slot 32 extends outward to form a covering edge 33. The covering edge 33 is arranged in the vertical direction, and the covering edge 33 includes an outer covering edge 331 and an inner covering edge 332 that are parallel to each other.

[0039] When the insertion arm 22 is inserted into the insertion slot 32, the insertion end 221 of the insertion arm 22 is inserted into the insertion slot 32 through the slot opening of the insertion slot 32. At the same time, the outer edge 331 and the inner edge 332 cover the part of the insertion arm 22 that is exposed outside the insertion slot 32 after insertion, further improving the connection tightness between the insertion arm 22 and the insertion slot 32 and preventing the slurry from flowing out of the connection gap between the two.

[0040] See Figures 2 to 4 As shown, the first split mold 2 includes a main body 23. A reinforcement plate 24 is connected to the main body 23. The reinforcement plate 24 is parallel to the insertion arm 22. The second split mold 3 includes a body 34. A fixing plate 35 is connected to the body 34. The fixing plate 35 is parallel to the insertion slot 32. A rotating connector is provided between the reinforcement plate 24 and the fixing plate 35. In this embodiment, the rotating connector is a bolt.

[0041] After the insertion arm 22 is inserted into the insertion slot 32, the reinforcement plate 24 and the fixing plate 35 overlap each other. The reinforcement plate 24 and the fixing plate 35 are connected by bolts, thereby further strengthening the connection tightness between the first split mold 2 and the second split mold 3 and preventing the slurry from flowing out of the connection gap between the insertion arm 22 and the insertion slot 32.

[0042] See Figure 1 and Figure 4 As shown, a connecting plate 21 is provided between the main body 23 and the reinforcement plate 24. The connecting plate 21 extends outward in a direction perpendicular to the reinforcement plate 24 to form a stop end 211 for abutting against the fixing plate 35. A joint plate 31 is provided between the body 34 and the fixing plate 35. And a limiting end 311 for abutting against the reinforcement plate 24 is provided on the end face of the joint plate 31 facing the connecting plate 21.

[0043] See Figure 1 and Figure 6 As shown, after the insertion arm 22 is inserted into the insertion slot 32, the reinforcement plate 24 and the fixing plate 35 overlap each other, and at this time, the side wall of the fixing plate 35 just abuts against the stop end 211 of the connecting plate 21, and the side wall of the reinforcement plate 24 just abuts against the limiting end 311 of the joint plate 31. In this embodiment, through the structural arrangement among the reinforcement plate 24, the fixing plate 35, the connecting plate 21 and the joint plate 31, the stop end 211 and the limiting end 311 are used to position the reinforcement plate 24 and the fixing plate 35, facilitating the mutual positioning of the mounting holes for installing the rotating connector on the reinforcement plate 24 and the fixing plate 35, further improving the convenience of disassembly and installation between the first split mold 2 and the second split mold 3, and at the same time preventing the connection between the first split mold 2 and the second split mold 3 from being loose due to misalignment of the reinforcement plate 24 and the fixing plate 35.

[0044] See Figure 1 and Figure 7As shown, a base is provided below the vertical pipe mold assembly 1. The base is provided with a groove rail 7 with an upward opening, and the vertical pipe mold assembly 1 is inserted into the groove rail 7. In this embodiment, the cross-section of the groove rail 7 is a closed annular quasi-elliptical structure. Through the setting of the groove rail 7, it is avoided that the unfixed concrete slurry flows out from the demolding opening 4 during the production process. A detachable connection method of plug-in is adopted between the groove rail 7 and the vertical pipe mold assembly 1, which further improves the convenience of disassembly and installation between the first split mold 2 and the second split mold 3.

[0045] See Figure 1 and Figure 8 As shown, the base further includes a support protection frame 8. The groove rail 7 is arranged inside the support protection frame 8, and the support protection frame 8 includes side enclosing plates 81 wound around the periphery of the vertical pipe mold assembly 1. The side enclosing plates 81 are connected with mounting plates 82 for connecting to the ground. In this embodiment, the mounting plates 82 are connected to the ground by bolts.

[0046] Through the setting of the support protection frame 8, enclosed protection is provided for the vertical pipe mold assembly 1 to prevent the vertical pipe mold assembly 1 from being accidentally collided and toppled during the production process.

[0047] In addition, a file folder slot 83 for placing an information board can be provided on the side enclosing plate 81 to record production information for the convenience of production management of the hollow pipe piles.

[0048] See Figure 6 As shown, the vertical pipe mold assembly 1 is provided with a hollow channel 6 arranged in the vertical direction, and the hollow channel 6 has a non-circular structure.

[0049] See Figure 1 As shown, the pouring ports 5 at the upper ends of the first split mold 2 and the second split mold 3 respectively include at least two spaced-apart sub-holes 51. Through the setting of the sub-holes 51, after the slurry is poured into the first split mold 2 and the second split mold 3, it is more uniform.

[0050] Of course, the above drawings are only the preferred embodiments of the present invention, and are not used to limit the scope of use of the present invention. Therefore, all equivalent changes made on the principle of the present invention should be included in the protection scope of the present invention.
