[0002] The centrifugal pile body has good homogeneity and high strength. During the production process, the excess air and moisture in the pile body are discharged through centrifugal technology, reducing the need and cost of future maintenance. The centrifugal pile body has excellent performance in bearing capacity and stability. Therefore, the centrifugal pile is widely used in construction materials. However, the centrifugal pile molds on the market are of a single style and cannot meet various pile use requirements. For example, the patent with application number 202410317926.7 discloses a centrifugal forming mold for concrete precast piles, which uses the cooperation between the female tenon strip, the male tenon cavity and the male tenon cavity filling strip to achieve the concave and convex tenon structural requirements of different centrifugal piles. However, in the actual production process, the female tenon strip, the male tenon cavity and the filling strip will adhere to the concrete after use, affecting the concave and convex tenon structural quality of the centrifugal mold production pile body, and the conventional concrete pile mold does not have an interlocking function of the pile. If the concave and convex tenon in the mold is an embedded part, the precision of the produced pile can be improved, and the interlocking function of the concrete pile can be added to the mold. However, how to fix the concave and convex tenon is the primary problem to be solved, so as to meet various mold pile needs. Utility Model Content

[0043] In addition, in the description of the present utility model, unless otherwise specified, "multiple", "multiple groups" and "multiple roots" mean two or more.

[0044] Unless otherwise specified, the materials, instruments and methods used in the following embodiments are conventional materials, instruments and methods in the art and can be obtained through commercial channels.

[0045] Example 1

[0046] like Figure 1 , Figure 2 and Figure 2-1 As shown, the present embodiment is a centrifugal concrete pile mold with concave and convex tenons, and the mold composition includes a running circle 1, a reinforcing rib 2, an end plate 3 and a pipe mold 4, and a concave tenon embedded part 6 and a convex tenon embedded part 7 are fixed in the pipe mold. The pipe mold wall 41 of the pipe mold is tightly connected to the open end of the concave tenon embedded part groove 61 through a fastening device, and the pipe mold wall and the outer contour of the opening of the concave tenon embedded part groove partially overlap, and a buffer leak-proof sheet can be placed in the overlapping part. The buffer leak-proof sheet is generally made of a flexible material, such as rubber, silicone, straw rope, cotton thread, sponge, etc., which plays a role in increasing friction and strengthening close contact, and has the effect of preventing leakage and strengthening fixation. In addition, a pipe mold wall groove 97 is set at the contact part between the pipe mold and the open end of the concave tenon embedded part groove 61, so that a part of the open end of the concave tenon embedded part groove is embedded in the pipe mold wall, which also plays a role in increasing friction and strengthening close contact, and at the same time prevents the opening of the concave tenon embedded part groove from expanding when the fastening device is over-tightened, so as to avoid leakage of slurry due to a gap between the concave tenon embedded part and the pipe mold wall.

[0047] The tube mold wall 41 has a thin groove 81 at one end for fixing the tenon embedded part 7, and the tube mold wall 41 has a through groove 91 connected to the thin groove 81. The space of the through groove 91 completely accommodates the head end 72 of the tenon embedded part. The through groove 91 extends longitudinally along the tube mold direction. The longitudinal extension of the through groove 91 can be through or spaced. The cross-sectional shape of the through groove 91 is not limited, and is generally semicircular, circular and square or consistent with the shape of the head end 72 of the tenon embedded part. The gap of the thin groove 81 is less than or equal to the thickness of the head end connection part 73 of the tenon embedded part, so that when the mold is closed, it can generate a tight pressure on the head end connection part 73 of the tenon embedded part, thereby fixing the tenon embedded part.

[0048] A tube mold through groove 93 is provided at the close connection between the tube mold 4 and the groove 61 of the tenon pre-embedded part, and a magnetic suction device 101 is placed in the tube mold through groove 93. The tube mold through groove 93 is a long groove or a short groove arranged at intervals in the longitudinal direction of the tube mold. When the tenon pre-embedded part is made of iron or steel, the tenon pre-embedded part can be directly adsorbed and fixed to the tube mold through groove 93 by magnetic suction and tightly connected to the tube mold wall, thereby achieving a fixing effect.

[0049] Example 2

[0050] like Figure 2 , Figure 2-1 and Figure 8As described, this embodiment further includes a fixing rod 100 that is inserted into the groove 61 of the tenon embedded part on the basis of the embodiment 1. One fixing method is that there is an end plate hole groove 94 on the end plate 3 that is in communication with the groove 61 of the tenon embedded part, and the end plate is fixed at both ends of the pipe mold. The fixing rod 100 passes through the tenon embedded part 6 and the end plate 3 to achieve a fixing effect; another fixing method is that after the fixing rod is inserted into the tenon embedded part, if the fixing rod is made of magnetic metal, it can be adsorbed by the magnetic suction device 101 in the embodiment 1, and the tenon embedded part is fixed by the magnetic suction force. The above embodiments have no requirements on the shape of the fixing rod. The cross-sectional shape of the fixing rod can be consistent with the groove of the tenon embedded part to achieve a fixing effect after insertion, and it can also be partially inserted with the groove of the tenon embedded part to achieve a fixing effect.

[0051] Example 3

[0052] like Figure 3 , Figure 4 and Figure 4-1 As shown, in this embodiment, on the basis of embodiment 2, a groove 92 is provided on the fixing rod 100, and a magnetic block 102 is provided in the groove 92. The magnetic block 102 passes through the tube mold wall 41 and contacts with the magnetic device 101, so as to play a role in positioning and strengthening the magnetic fixing effect. The magnetic block 102 or the iron block 103 is placed in the groove of the fixing rod 100. The magnetic block 102 or the iron block 103 has a groove, which is embedded in the closed part of the tube mold 4. At the same time, the magnetic block 102 or the iron block 103 also passes through the tube mold wall 41, so that the magnetic block 102 or the iron block 103 is completely fixed when closed, so as to achieve the effect of fixing the fixing rod and the tenon embedded part. At the same time, a magnetic device 101 can be further provided outside the tube mold wall 41 to increase the magnetic attraction force and thus strengthen the fixing effect, and also achieve the positioning effect through the magnetic attraction force.

[0053] Example 4

[0054] like Figure 5 and Figure 5-1 As shown, on the basis of Example 2, the groove 97 of the tube mold wall is engaged with the embedded part of the groove of the tenon embedded part, which plays a role of preliminary fixing and engaging. In one case, the fixing rod 100 has threads, and the fastening bolts matching the threads pass through the tube mold and are connected to the fixing rod 100. In this case, the material of the fixing rod is metal or non-metallic polymer material, and there is no restriction on the material of the fixing rod when connected with the fastening bolts. In another case, there is no thread on the fixing rod, for example, the fixing rod is a nylon rod, and a self-tapping screw is used to pass through the tube mold and be directly connected to the fixing rod 100. The tenon embedded part is further fixed by the fastening bolts or the self-tapping screws combined with the fixing rod, which plays a role in preventing the tenon embedded part from shifting or falling off during the centrifugal process.

[0055] Example 5

[0056] like Figure 6 and Figure 6-1As shown, on the basis of Example 1, a threaded fastener 104 is provided on the wall of the tube mold, and the threaded fastener passes through the wall of the tube mold and is threadedly connected to the tenon embedded part. The threaded fastener can be a fastening bolt or a self-tapping screw, and threads can be provided on the tenon embedded part, and the fastening bolt is threadedly connected to the tenon embedded part to achieve a fixing effect; in another case, the tenon embedded part is a non-metallic polymer material, and the self-tapping screw directly acts on the tenon embedded part, and can be fixed even when the tenon embedded part is not threaded; in another case, the threaded fastener passes through the fixing rod and the tenon embedded part in Example 4 at the same time, and plays the effect of fixing the tenon embedded part.

[0057] Example 6

[0058] like Figure 7 , Figure 7-1 , Fig.11 and Fig.12 As shown, on the basis of Example 1, this embodiment further includes a fixed valve 5 for fixing the tenon embedded part, the fixed valve 5 includes a pin rod 51 and a fixed valve plate 52, the fixed valve plate 52 is fixed to the upper end of the pin rod 51, the pin rod 51 is rotatably installed on the pipe mold wall 41, the fixed valve plate 52 extends into the groove 61 of the tenon embedded part, the outer contour of the fixed valve plate 52 is rotationally fitted with the inner contour of the groove 61, and the positioning block 53 is used to fix the fixed valve plate 52 and the pipe mold wall 41 after the position is determined. The number of fixed valves 5 is not less than one, and the fixed valve 5 is fixed at The maximum value of the vector distance in the open direction of the tenon embedded part groove 61 is greater than the cross-sectional open distance of the tenon embedded part groove 61, the maximum value of the vector distance in the open direction of the tenon embedded part groove of the fixed valve 5 is less than or equal to the maximum value of the open direction of the tenon embedded part groove, the fixed valve and the outer fastening bolt parts are staggered, the outer contour of the fixed valve plate 52 and the inner contour of the groove 61 can be fully or partially fitted after rotation, the shape of the fixed valve plate is not limited to a circle, as long as the shape of the fixed valve plate can be inserted and fixed with the tenon embedded part groove, such as Fig.13 The shown concave and mortise shaped groove and the fixed valve plate that cooperates with it.

[0059] Example 7

[0060] like Fig. 9 , Figure 9-1 , Fig.10 , Figure 10-1 and Fig.14As shown, the present embodiment limits the concave and convex tenon embedded parts of the above-mentioned embodiments, the open distance of the concave and convex tenon embedded part groove 61 is smaller than the maximum value of the vector distance in the open direction of any two points of the concave and convex tenon embedded part groove 61, the head end 72 of the convex tenon embedded part is included in the hollow area of ​​the concave and convex tenon embedded part groove 61, the open distance of the concave and convex tenon embedded part groove 61 is smaller than the maximum value of the vector distance in the open direction of the groove of any two points of the head end 72 of the convex tenon embedded part, the cross-sectional shape of the head end of the convex tenon embedded part is semicircular, circular, triangular, quadrilateral, pentagonal, hexagonal, T-shaped, I-shaped, U-shaped or other polygonal or irregular closed figures, the cross-sectional shape of the head end of the concave and convex tenon embedded part can be consistent with the cross-sectional shape of the head end of the convex tenon embedded part, the cross-sectional shape of the head end of the concave and convex tenon embedded part is larger than the convex tenon embedded part, the cross-sectional shape of the head end of the concave and convex tenon embedded part can also be inconsistent with the cross-sectional shape of the head end of the convex tenon embedded part, the head end of the convex tenon embedded part It can be completely placed in the tenon and mortise embedded part, so that the groove 61 of the tenon and mortise embedded part and the head end 72 of the convex tenon embedded part are locked laterally and cannot be separated after being interlocked with each other. When the gap between the tenons and mortise is large, it can also provide the tenon and mortise with rotational space. Below the head end 72 of the convex tenon embedded part is the anti-slip reinforcement 71 of the convex tenon embedded part 7, and below the groove 61 of the tenon and mortise embedded part is also equipped with an anti-slip reinforcement. The anti-slip reinforcement includes ribs 98, anti-slip grooves 96 or through holes 95 on the tenon and mortise embedded part. The anti-slip grooves 96 or through holes 95 are optional necessary conditions, or the ribs, anti-slip grooves and through holes are any combination, or the three exist at the same time.

The shape of the through hole 95 or the anti-slip groove 96 is one or more combinations of semicircular, circular, triangular, square, pentagonal and hexagonal.

[0061] The structural setting of the mortise and tenon embedded parts can meet the needs of various pile uses, and it can be achieved by simply replacing the mortise and tenon embedded parts. There is no need to transport, replace or disassemble the pile body, so as to achieve the effect of rapid mold installation and improve production efficiency. In addition, the mortise and tenon embedded parts are disposable and can be made of metal or non-metallic polymer materials. At present, the embedded parts use metal or polymer materials with a processing accuracy of less than 0.5mm, which greatly improves the assembly accuracy between piles, expands the adaptability of pile bodies, meets different pile body needs, and reasonably controls pile body costs. In addition, disposable embedded parts can drive the linkage between upstream and downstream suppliers and promote economic circulation.
