For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] For the purpose of simplicity and illustration, the principles of the embodiments are described mainly by reference to examples. In the following description, many specific details are presented to provide a thorough understanding of the embodiments. However, it is obvious to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments may be used in combination with each other.

[0040] See also Figures 1 to 7, the utility model provides a technical solution:

[0041] Embodiment 1: A special mold for imitation wood concrete piles with plug-in connection, the special mold comprising a side mold 2 and a bottom mold 1, the cavity formed when the side mold 2 and the bottom mold 1 are closed constitutes a casting mold cavity 7 of the special-shaped imitation wood concrete pile, and end plates for sealing the casting mold cavity 7 are installed at both longitudinal ends of the casting mold cavity 7.

[0042] The imitation wood concrete pile is cast through the formed casting mold cavity 7.

[0043] An inner skeleton 3 is provided in the casting mold cavity 7, and a lower opening groove 6 and a plug column 5 which can be plugged into each other are provided on the inner skeleton 3. A positioning device for fixing the inner skeleton 3 is provided on the bottom mold 1, and the positioning device is set as a pin rod 8 and a positioning piece 11. The pin rod 8 is rotatably installed on the bottom mold 1, and the positioning piece 11 is fixed at the upper end of the pin rod 8. The positioning piece 11 extends into the lower opening groove 6, and the outer contour of the positioning piece 11 is rotationally fitted with the inner contour of the lower opening groove 6. The thickness of the positioning piece 11 is smaller than the opening width of the lower opening groove 6, and the opening angle of the lower opening groove 6 is less than 180 degrees. The outer wall of the lower end of the lower opening groove 6 is pressed on the bottom mold 1, and the inner contour of the lower opening groove 6 can be set to be circular, square, polygonal or a combination of shapes.

[0044] The positioning device is provided to realize the positioning and locking functions of the inner frame 3. After locking, it is ensured that the concrete slurry cannot leak into the lower opening groove 6 through the gap between the inner frame 3 and the bottom mold 1. In actual application, the lower opening groove 6 and the plug column 5 of the finished imitation wood pile are inserted and locked. No concrete can be poured into the lower opening groove 6, otherwise the piles cannot be smoothly locked.

[0045] Working principle: During the installation process, the thickness of the positioning piece 11 is smaller than the opening width of the lower opening groove 6, so that the positioning piece 11 is conveniently inserted into the lower opening groove 6. When the inner frame 3 is installed in place, the positioning piece 11 is driven to rotate by the rotation of the pin rod 8 on the bottom mold 1, so that the positioning piece 11 is rotated and pressed on the lower opening groove 6.

[0046] Since the opening angle of the lower opening groove 6 is less than 180 degrees, the lower inner wall of the positioning piece 11 is rotated and pressed against the lower inner wall of the lower opening groove 6 to achieve the purpose of rotational close fitting, thereby achieving the purpose of fixing while realizing the positioning of the inner skeleton 3. The positioning piece 11 is pressed against the lower inner wall of the lower opening groove 6, so that the lower outer wall of the lower opening groove 6 is tightly pressed on the bottom mold 1, ensuring that concrete and slurry cannot leak into the inner cavity of the lower opening groove 6 from the intersection of the lower opening groove 6 and the bottom mold 1 where the inner skeleton 3 is located in the casting mold cavity 7.

[0047] Embodiment 2: On the basis of embodiment 1, a positioning ring 13 is further provided on the pin rod 8, and a hole 14 is opened on the bottom mold 1. The middle section of the pin rod 8 is inserted in the hole 14. The vertical insertion of the pin rod 8 is realized by setting the hole. A handle 15 is provided at the lower end of the pin rod 8. The handle 15 is used to conveniently drive the pin rod 8. The positioning ring 13 is located at the lower end of the hole 14 on the bottom mold 1. The outer diameter of the positioning ring 13 is larger than the inner diameter of the hole 14, and the inner diameter of the positioning ring 13 is not smaller than the outer diameter of the pin rod 8. The position of the pin rod 8 is limited by setting the positioning ring 13. The distance between the upper part of the positioning ring 13 of the pin rod 8 and the bottom of the positioning piece 11 is larger than the thickness of the bottom mold 1, and smaller than the thickness of the bottom mold 1 plus the wall thickness of the lower opening groove 6, thereby ensuring that the positioning piece 11 is inserted in the lower opening groove 6 and the inner wall of the lower opening groove 6 is squeezed and locked.

[0048] Embodiment 3: Based on embodiment 1, a middle through hole 4 is provided in the middle of the inner frame 3, and a fixing structure which is sleeved with the inner frame 3 is provided on the side wall of the end plate.

[0049] By setting the fixing structure and cooperating with the inner frame 3, the inner frame 3 can be further positioned and fixed.

[0050] Embodiment 4: On the basis of Embodiment 3, the fixed structure is set as a convex tube, which is inserted into the middle through hole 4, and the outer diameter of the end of the convex tube is smaller than the inner diameter of the middle through hole 4, or the convex tube is directly set as a cone head or a semi-sphere, and the diameter of the cone head at the farthest distance from the end plate is smaller than the middle through hole 4, and the diameter of the semi-sphere is smaller than the middle through hole 4.

[0051] The convex tube is provided to ensure the accurate positioning of the inner skeleton 3. The positioning of the inner skeleton 3 of the mold is also a necessary measure. The accurate position can ensure the smooth clamping of the lower opening groove 6 and the plug column 5 of the formed pile body. At the same time, the accurate position of the inner skeleton 3 is also one of the necessary parts to ensure the bending resistance of the formed pile body. By providing a convex tube on the inner wall of the end plate or directly providing the convex tube as a cone head or making the outer diameter of the convex tube smaller than the inner diameter of the middle through hole 4, it is convenient for the convex tube to be inserted into the middle through hole 4 of the inner skeleton 3, thereby improving the production efficiency.

[0052] Example 5: Based on Example 3, mold leakage will cause the strength of the concrete pile to decrease, so this setting indirectly guarantees the design strength of the concrete. The fixed structure is set as an elastic layer such as ethylene propylene diene monomer rubber EPDM, styrene SBS, SIS, etc. or a groove, and the end of the inner skeleton 3 is inserted in the elastic layer or the groove.

[0053] The ends of the inner frame 3 are sealed by setting grooves, thereby achieving the purpose of sealing the ends of the inner frame 3, avoiding leakage of slurry at the ends, ensuring that concrete and slurry do not leak into the middle through hole 4 of the inner frame 3, reducing concrete waste and saving costs.

[0054] Embodiment 6: On the basis of Embodiment 1, the side mold 2 extends longitudinally and is in an arc shape with an arc angle less than π / 2. The inner wall of the arc of the side mold 2 is provided with an imitation wood grain mold sheet or printed with imitation wood grain convex and concave grooves. The bottom mold 1 extends longitudinally and is a plane, an arc surface or a combination of a plane and an arc surface. The side mold 2 is provided with a locking device 12 for fixing the casting mold cavity 7. The locking device 12 is at least one of a quick locking buckle, a pin or a screw nut locker.

[0055] By setting an arc-shaped inner wall of the side mold 2, a wood-like concrete pile with an arc outer wall is formed. By setting an imitation wood grain mold sheet or printing (pressing) imitation wood grain concave and convex grooves, it is convenient to form the imitation wood grain on the outer wall of the concrete pile. The locking device 12 is installed on the upper and lower sides of the side mold 2 to achieve the purpose of synchronous locking up and down. The locking device 12 is used to lock and fix the casting mold cavity 7, so as to achieve the purpose of limiting the inner contour of the casting mold cavity 7.

[0056] Embodiment 7: Based on embodiment 6, Figure 1 , 2 As shown, the side mold 2 is movably connected to the bottom mold 1, and at least one hinge point is provided at the lower overlap of the bottom mold 1 and the side mold 2. The hinge opening and closing point is located below the side mold 2, and the side molds 2 at both ends and the bottom mold 1 are rotated through the hinge point to open and close the mold.

[0057] Embodiment 8: Based on Embodiment 6, a slide rail 9 is provided under the bottom mold 1, and a roller 10 sliding along the slide rail 9 is provided at the lower end of the side mold 2.

[0058] The rollers 10 and the slide rails 9 are provided to realize the convenient and positioned opening and closing of the side mold 2 .

[0059] In Example 9, the number of side molds 2 is two, and the sliding of the side molds 2 can be adjusted by the scheme in Example 7 or 8.

[0060] Embodiment 9: Based on embodiment 8, Figure 3 , 4 As shown in Figures 5, the side molds 2 are opened and closed by sliding the rollers 10 on the slide rails 9. The side molds 2 are provided in three numbers. The middle group of side molds 2 is fixedly connected to the bottom mold 1, and the side molds 2 on both sides are movably connected to the bottom mold 1.
