Description

Technical Field

[0001] This utility model relates to the field of concrete tower technology, specifically to casting molds. Background Technology

[0002] With the continuous development of wind power technology, the power generation efficiency of wind turbines is constantly improving, leading to the continuous extension of wind turbine blade length. To support these longer blades and maintain operational stability, the corresponding wind turbine towers not only need to increase in height but also have larger cross-sectional dimensions due to structural strength requirements. However, traditional steel structure towers have significant drawbacks when facing the construction needs of large cross-sections and tall towers, including high costs and inconvenient transportation, making it difficult to effectively meet the development requirements of current and future wind power projects. In contrast, precast concrete towers, with their cost-effectiveness, have become an ideal choice for the economical and efficient construction of large wind turbine generators. However, current concrete tower construction technology mainly relies on hoisting precast tower sections layer by layer from bottom to top to complete the overall structural assembly. Furthermore, limited by the current design of concrete tower molds, it can only perform casting operations for tower sections or sections of specific sizes, lacking flexibility and making it difficult to adapt to the production needs of tower sections or sections with varying heights or curvatures, causing many inconveniences in practical engineering applications. Utility Model Content

[0003] In view of this, the present invention provides a casting mold to solve the problem that the current concrete tower mold is limited by its design and can only be used for casting operations on towers or tower sections of specific sizes, lacking flexibility and making it difficult to adapt to the production needs of towers and tower sections with different heights or curvatures.

[0004] This utility model provides a casting mold, including a bottom mold and side molds; the side molds are connected to the bottom mold; the side molds include multiple template units; some of the template units are connected sequentially in the circumferential direction to form a single-layer structure, and multiple single-layer structures are connected layer by layer in the height direction to form an inner module; the remaining template units are connected sequentially in the circumferential direction to form a single-layer structure, and multiple single-layer structures are connected layer by layer in the height direction to form an outer module; the outer module is radially sleeved on the outer periphery of the inner module and spaced apart from the inner module; the inner module, the outer module, and the bottom mold enclose a casting cavity.

[0005] Beneficial effects: Since both the inner and outer modules consist of multiple template units connected sequentially along the circumference to form a single-layer structure, and these single-layer structures are connected layer by layer along the height direction, the number of template units can be flexibly adjusted during actual construction. If the height of the concrete tower or concrete tower section needs to be changed, the number of template units can be increased or decreased accordingly in the height direction. If the arc length of the concrete tower section needs to be adjusted, it can be achieved by selecting different numbers of template units in the circumference direction for combination. This allows for efficient and precise adaptive adjustment of concrete towers or concrete tower sections of different specifications and sizes according to actual needs, enhancing the flexibility and adjustability of the casting mold.

[0006] In an optional embodiment, it further includes a pressure-bearing unit, each set of template units being connected to a corresponding set of pressure-bearing units, and the pressure-bearing unit being located on the side of the template unit away from the casting cavity; the pressure-bearing unit includes a first pressure-bearing member and two sets of second pressure-bearing members; the first pressure-bearing member extends along the height direction; the two sets of second pressure-bearing members are respectively arranged on both sides of the first pressure-bearing member along the circumferential direction, and the second pressure-bearing members extend along the circumferential direction.

[0007] Beneficial effects: Because the first bearing member extends along the height direction, it can effectively withstand pressure from the height direction; the second bearing member extends circumferentially, which can disperse and withstand circumferential pressure from the sides. Through the cooperation of the first and second bearing members, the overall pressure-bearing capacity of the inner and outer modules during concrete pouring is improved, making the module structure more stable and reliable. This effectively reduces the possibility of deformation of the pouring mold due to uneven stress or excessive pressure, ensuring the quality and precision of concrete pouring.

[0008] In one alternative embodiment, the device further includes a first connector that extends along the height direction; the first pressure-bearing member has a first connecting groove that extends along the height direction; and the first connector is slidably connected in two adjacent first connecting grooves.

[0009] Beneficial effects: Since the first connector is slidably connected in two adjacent first connecting slots, multiple single-layer structures can be connected sequentially in the height direction quickly and conveniently; at the same time, since it is a slidable connection, the connection can be easily released when disassembly is required, thereby realizing the rapid and convenient assembly and disassembly of multiple single-layer structures in the height direction, greatly improving construction efficiency and flexibility.

[0010] In one optional embodiment, the device further includes a first extrusion member, wherein a first connection hole is provided on the circumferential wall of the first connecting groove; the first extrusion member passes through the first connection hole and abuts against the first connecting member.

[0011] Beneficial effects: Since the first connecting hole is located on the circumferential groove wall of the first connecting groove, the first extrusion member passes through the first connecting hole and abuts against the first connecting member in the circumferential direction, generating an effective constraint force in the direction perpendicular to the first connecting member, thereby fixing the first connecting member and improving the stability and safety of the entire structure.

[0012] In one alternative embodiment, a second connector is further included, the second connector extending along the circumferential direction, and the second pressure-bearing member is provided with a second connecting groove extending along the circumferential direction; the second connector is slidably connected in two adjacent second connecting grooves.

[0013] Beneficial effects: Since the second connector is slidably connected in two adjacent second connecting slots, multiple template units can be connected sequentially in the circumferential direction quickly and conveniently; at the same time, since it is a slidable connection, the connection can be easily released when disassembly is required, thereby realizing the quick and convenient assembly and disassembly of multiple template units in the circumferential direction, which greatly improves construction efficiency and flexibility.

[0014] In one optional embodiment, a second extrusion member is further included, and a second connection hole is provided on the groove wall of the second connecting groove along the height direction; the second extrusion member passes through the second connection hole and abuts against the second connecting member.

[0015] Beneficial effects: Since the second connecting hole is located on the groove wall of the second connecting groove along the height direction, the second extruder passes through the second connecting hole along the height direction and abuts against the second connector, generating an effective constraint force in the direction perpendicular to the second connector, thereby fixing the second connector and improving the stability and safety of the entire structure.

[0016] In one optional embodiment, a first positioning component is further included, the first positioning component including a positioning hole and a first positioning element; the positioning hole is disposed on the bottom mold; the first positioning element protrudes from the bottom of the template unit near the bottom mold and extends into the positioning hole.

[0017] Beneficial effects: With the design of the first positioning element and positioning hole, the first positioning element can be accurately embedded in the positioning hole when the template unit is placed on the bottom mold. This matching method not only provides clear guidance for the installation of the template unit, but also achieves precise pre-positioning of the template unit on the bottom mold, thereby effectively avoiding possible deviations during the installation process and improving installation efficiency and quality.

[0018] In one optional embodiment, a connecting structure is further included, the connecting structure including a third connecting hole, a through hole and a connector; the third connecting hole is disposed on the side of the template unit near the bottom mold; the through hole is disposed on the bottom mold; one end of the connector is located on the side of the bottom mold away from the template unit, and the other end passes through the through hole and connects to the third connecting hole.

[0019] Beneficial effects: Since one end of the connector is located on the side of the bottom mold away from the template unit, it ensures that it will not interfere with the normal installation and use of the template unit; the other end of the connector passes through the pre-set through hole on the bottom mold and connects with the corresponding third connection hole on the template unit, ensuring the rationality and stability of the connector in terms of structure, and effectively realizing a reliable connection between the template unit and the bottom mold.

This not only helps to accurately align the two adjacent first connecting grooves, but also provides the necessary conditions for the first connecting component to slide smoothly into the two adjacent first connecting grooves, enabling a quick, stable and detachable connection between the two adjacent template units, thus improving installation efficiency.

[0022] In an alternative embodiment, a lifting hole is also included, which is located at the bottom of the casting cavity and disposed on the bottom mold.

[0023] Beneficial effects: By setting up lifting holes, the lifting rod of the lifting mechanism can extend into the casting cavity through the lifting holes and directly contact the bottom of the cast concrete tower plate or concrete tower cylinder, and apply an upward thrust, thereby pushing the concrete tower plate or concrete tower cylinder to rise gradually. This achieves effective separation of the concrete tower plate or concrete tower cylinder from the inner wall of the casting cavity, simplifies the demolding process, improves work efficiency, and ensures the integrity and quality of the concrete tower plate or concrete tower cylinder during the demolding process.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0033] According to an embodiment of the present invention, a casting mold is provided, including a bottom mold 01 and a side mold 02; the side mold 02 is connected to the bottom mold 01; the side mold 02 includes a plurality of template units 021; wherein some of the template units 021 are connected sequentially in the circumferential direction to form a single-layer structure, and the plurality of single-layer structures are connected layer by layer in the height direction to form an inner module 022; the remaining template units 021 are connected sequentially in the circumferential direction to form a single-layer structure, and the plurality of single-layer structures are connected layer by layer in the height direction to form an outer module 023; the outer module 023 is radially sleeved on the outer periphery of the inner module 022 and spaced apart from the inner module 022; the inner module 022, the outer module 023 and the bottom mold 01 enclose to form a casting cavity 03.

[0034] Since both the inner module 022 and the outer module 023 have multiple template units 021 connected sequentially along the circumference to form a single-layer structure, and multiple single-layer structures are connected layer by layer along the height direction to form a single-layer structure, the number of template units 021 can be flexibly adjusted during actual construction: if the height of the concrete tower or concrete tower section needs to be changed, the number of template units 021 can be increased or decreased accordingly in the height direction; if the arc length of the concrete tower section needs to be adjusted, it can be achieved by selecting different numbers of template units 021 in the circumference direction for combination. It can efficiently and accurately adapt to different specifications and sizes of concrete towers or concrete tower sections according to actual needs, enhancing the flexibility and adjustability of the casting mold.

[0035] In a specific embodiment, the casting cavity 03 is annular or arc-shaped. When the casting cavity 03 is arc-shaped, the two ends of the inner module 022 and the outer module 023 are connected by connecting plates to form a closed structure along the circumferential direction.

[0036] In one embodiment, a pressure-bearing unit 04 is also included. Each set of template units 021 is correspondingly connected to a set of pressure-bearing units 04, and the pressure-bearing unit 04 is located on the side of the template unit 021 away from the casting cavity 03. The pressure-bearing unit 04 includes a first pressure-bearing member 041 and two sets of second pressure-bearing members 042. The first pressure-bearing member 041 extends along the height direction. The two sets of second pressure-bearing members 042 are respectively arranged on both sides of the first pressure-bearing member 041 along the circumferential direction, and the second pressure-bearing members 042 extend along the circumferential direction.

[0037] Because the first pressure-bearing component 041 extends along the height direction, it can effectively withstand pressure from the height direction; the second pressure-bearing component 042 extends circumferentially, which can disperse and withstand circumferential pressure from the sides. Through the cooperation of the first pressure-bearing component 041 and the second pressure-bearing component 042, the overall pressure-bearing capacity of the inner module 022 and the outer module 023 during the concrete pouring process is improved, making the module structure more stable and reliable. This effectively reduces the possibility of deformation of the pouring mold due to uneven force or excessive pressure, and ensures the quality and accuracy of concrete pouring.

[0038] In a specific implementation, the first pressure-bearing component 041 may be made of I-beams or channel steel, etc.

[0039] In a specific implementation, the length of the first pressure-bearing member 041 can be set as needed. Preferably, the length of the first pressure-bearing member 041 can be the same as the height of the template unit 021.

[0040] In one embodiment, the device further includes a first connector 05 that extends along the height direction; the first pressure-bearing member 041 is provided with a first connecting groove 0411 that extends along the height direction; the first connector 05 is slidably connected in two adjacent first connecting grooves 0411.

[0041] Since the first connector 05 is slidably connected in two adjacent first connecting slots 0411, multiple single-layer structures can be connected sequentially in the height direction quickly and conveniently. At the same time, since it is a slidable connection, the connection can be easily released when disassembly is required, thereby realizing the quick and convenient assembly and disassembly of multiple single-layer structures in the height direction, which greatly improves construction efficiency and flexibility.

[0042] In a specific implementation, in the height direction, multiple first pressure-bearing members 041 connected to the multi-layer template unit 021 are aligned and cooperate with each other, which facilitates the alignment of two adjacent first connecting slots 0411 and helps the first connecting member 05 to slide in the two adjacent first connecting slots 0411.

[0043] Preferably, the first connecting groove 0411 has a first opening on the side opposite to the casting cavity 03; and the distance between the two sides of the first connecting groove 0411 along the circumferential direction is greater than the distance between the two sides of the first opening along the circumferential direction; thus forming a first connecting groove 0411 with a large cavity and a small opening inside the first pressure member 041, which can prevent the first connecting member 05 from separating from the first pressure member 041, facilitate the observation of the position of the first connecting member 05 in the first connecting groove 0411, facilitate the judgment of whether the first connecting member 05 is properly connected, and also help to push the first connecting member 05 to slide in the first connecting groove 0411, which is convenient for adjusting the position of the first connecting member 05.

[0044] In one embodiment, the device further includes a first extrusion member 06, and the first connecting groove 0411 has a first connecting hole 0412 on its circumferential groove wall; the first extrusion member 06 passes through the first connecting hole 0412 and abuts against the first connecting member 05.

[0045] Since the first connecting hole 0412 is located on the circumferential groove wall of the first connecting groove 0411, the first extrusion member 06 passes through the first connecting hole 0412 in the circumferential direction and abuts against the first connector 05, generating an effective constraint force in the direction perpendicular to the first connector 05, thereby fixing the first connector 05 and improving the stability and safety of the entire structure.

[0046] Specifically, the first extrusion member 06 can be a bolt, and the first connecting hole 0412 can be a threaded hole.

[0047] In a specific implementation, in the height direction, the length of the first connecting groove 0411 corresponding to the template unit 021 located at the bottom is less than the length of the first pressure member 041, and the first connecting groove 0411 is located on the side away from the bottom mold 01, which facilitates the sliding connection between the first connecting member 05 and the first connecting groove 0411, and the first pressure member 041 is partially inserted by the first connecting member 05.

[0048] In another embodiment, the length of the first connecting groove 0411 corresponding to the template unit 021 at the bottom in the height direction is equal to the length of the first pressure member 041, and the first pressure member 041 is completely inserted by the first connecting member 05.

[0049] In a specific implementation, multiple first connectors 05 are provided, with one first connector 05 between every two adjacent first connecting slots 0411 along the height direction. When installing multiple single-layer structures from bottom to top, the bottommost single-layer structure is installed first, followed by the second layer. The first connecting slots 0411 of the second layer are aligned with the bottommost first connecting slot, and then the first first connector 05 extends from the second layer's first connecting slot 0411 into the bottommost first connecting slot. Then, the third layer is installed, with the first connecting slots 0411 of the third layer aligned with the second layer's first connecting slot, and then the second first connector 05 extends from the third layer's first connecting slot into the second layer's first connecting slot. This process continues until the top single-layer structure is installed.

[0050] In another embodiment, a first connector 05 may be provided, with one first connector 05 passing through multiple first connecting slots 0411 in sequence. After multiple single-layer structures are stacked layer by layer along the height direction, the first bearing members 041 on each template unit 021 in the same column are aligned with each other axially. Then, the first connectors 05 are inserted into the multiple first connecting slots 0411 in sequence, and then the first connectors 05 are fixed by the first pressing member 06. This connects the template units 021 in the same column into a whole and fixes their radial positions.

[0051] In one embodiment, a second connector 07 is further included, which extends along the circumferential direction. The second pressure-bearing member 042 is provided with a second connecting groove 0421 extending along the circumferential direction. The second connector 07 is slidably connected in two adjacent second connecting grooves 0421.

[0052] Since the second connector 07 is slidably connected in two adjacent second connecting slots 0421, multiple template units 021 can be connected sequentially in the circumferential direction quickly and conveniently. At the same time, since it is a slidable connection, the connection can be easily released when disassembly is required, thereby realizing the quick and convenient assembly and disassembly of multiple template units 021 in the circumferential direction, which greatly improves construction efficiency and flexibility.

[0053] In a specific implementation, in the circumferential direction, multiple second pressure-bearing members 042 connected to the multi-layer template unit 021 are aligned and cooperate with each other, which facilitates the alignment of two adjacent second connecting grooves 0421 and helps the second connecting member 07 to slide in the two adjacent second connecting grooves 0421.

[0054] In a specific implementation, since the casting cavity 03 is annular or arc-shaped, the template unit 021 is arc-shaped along the circumferential direction. Specifically, the second pressure-bearing member 042 and the second connecting member 07 are also arc-shaped, matching the shape of the template unit 021.

[0055] Preferably, the second connecting groove 0421 has a second opening on the side opposite to the casting cavity 03; and the distance between the two side walls of the second connecting groove 0421 along the height direction is greater than the distance between the two side walls of the second opening along the height direction; thus forming a second connecting groove 0421 with a large cavity and a small opening inside the second pressure member 042, which can prevent the second connecting member 07 from separating from the second pressure member 042, facilitate the observation of the position of the second connecting member 07 in the second connecting groove 0421, facilitate the judgment of whether the second connecting member 07 is connected in place, and also help to push the second connecting member 07 to slide in the second connecting groove 0421, which is convenient for adjusting the position of the second connecting member 07.

[0056] In one embodiment, a second extrusion member 08 is further included, and a second connection hole 0422 is provided on the groove wall of the second connecting groove 0421 along the height direction; the second extrusion member 08 passes through the second connection hole 0422 and abuts against the second connecting member 07.

[0057] Since the second connecting hole 0422 is located on the groove wall of the second connecting groove 0421 along the height direction, the second extrusion member 08 passes through the second connecting hole 0422 along the height direction and abuts against the second connecting member 07, generating an effective constraint force in the direction perpendicular to the second connecting member 07, thereby fixing the second connecting member 07 and improving the stability and safety of the entire structure.

[0058] Specifically, the second extrusion member 08 can be a bolt, and the second connecting hole 0422 can be a threaded hole.

[0059] In a specific implementation, during installation, the second connector 07 is first slid into the second connecting groove 0421. After the two adjacent template units 021 in the circumferential direction are aligned, the second connector 07 is pushed to move through the second opening, so that the two ends of the second connector 07 are respectively located in the two adjacent second connecting grooves 0421 in the circumferential direction. Then, the second connector 07 is fixed by the second pressing member 08, so that the two adjacent modules in the circumferential direction can be connected and fixed to each other.

[0060] In one embodiment, a first positioning component is further included, the first positioning component including a positioning hole 091 and a first positioning element 092; the positioning hole 091 is disposed on the bottom mold 01; the first positioning element 092 protrudes from the bottom of the template unit 021 near the bottom mold 01 and extends into the positioning hole 091.

[0061] With the first positioning element 092 and the positioning hole 091, when the template unit 021 is placed on the bottom mold 01, the first positioning element 092 can be accurately embedded in the positioning hole 091. This cooperation method not only provides clear guidance for the installation of the template unit 021, but also realizes the precise pre-positioning of the template unit 021 on the bottom mold 01, thereby effectively avoiding possible deviations during the installation process and improving installation efficiency and quality.

[0062] In a specific implementation, the first positioning member 092 can be fixed on the bottom wall of the template unit 021 near the bottom mold 01, or it can be fixed on the side wall of the template unit 021 near the bottom mold 01 away from the casting cavity 03.

[0063] In specific embodiments, the shapes of the first positioning member 092 and the positioning hole 091 are not limited; the first positioning member 092 can be a rod-shaped structure and the positioning hole 091 can be a round hole; or the first positioning member 092 can be a rectangular structure and the positioning hole 091 can be a rectangular hole.

[0064] In one embodiment, a connecting structure is further included, the connecting structure including a third connecting hole 101, a through hole 102, and a connector 103; the third connecting hole 101 is disposed on the side of the template unit 021 near the bottom mold 01; the through hole 102 is disposed on the bottom mold 01; one end of the connector 103 is located on the side of the bottom mold 01 away from the template unit 021, and the other end passes through the through hole 102 and is connected to the third connecting hole 101.

[0065] Since one end of the connector 103 is located on the side of the bottom mold 01 away from the template unit 021, it ensures that it will not interfere with the normal installation and use of the template unit 021; the other end of the connector 103 passes through the preset through hole 102 on the bottom mold 01 and is connected to the corresponding third connection hole 101 on the template unit 021, ensuring the structural rationality and stability of the connector 103 and effectively realizing the reliable connection between the template unit 021 and the bottom mold 01.

[0066] In a specific implementation, the connector 103 can be a fastener such as a bolt.

[0067] In a specific implementation, each set of template units 021 is provided with two sets of connection structures, and the two sets of connection structures are respectively arranged on both sides of the first positioning component along the circumferential direction.

[0068] In a specific implementation, to enhance the strength and density of the concrete tower or concrete tower sections and reduce cracks, corrugated pipes need to be pre-embedded within the concrete tower or concrete tower sections during concrete pouring. Specifically, a corrugated pipe fixing plate 11 is provided at the top of the pouring cavity 03, and the corrugated pipe fixing plate 11 is used to install the corrugated pipes. Specifically, both ends of the corrugated pipe fixing plate 11 are fixed to the top of the inner module 022 and the outer module 023, respectively. In a specific implementation, a fourth connecting hole 12 is provided on the top module unit, and a fifth connecting hole is provided at the end of the corrugated pipe fixing plate 11. Fasteners pass through the fifth connecting hole and connect to the fourth connecting hole 12.

[0069] In a specific implementation, by changing the number of single-layer structures located in the middle along the height direction, the pouring of concrete tower cylinders or concrete tower sections at different heights can be achieved. This ensures that, regardless of the change in the number of single-layer structures along the height direction, the shape of the template unit 021 located at the top or bottom remains unchanged, ensuring the connection between the inner module 022 and the outer module 023 and the bottom mold 01 and the corrugated pipe fixing plate 11.

[0070] In specific implementations, the number of intermediate single-layer structures along the height direction is not limited; it can be one, two, or three layers. When there is only one intermediate single-layer structure, it is detachably connected to the top and bottom single-layer structures. When there are two intermediate single-layer structures, the two intermediate single-layer structures are detachably connected to each other, with the upper intermediate single-layer structure detachably connected to the top single-layer structure, and the lower intermediate single-layer structure detachably connected to the bottom single-layer structure.

[0071] In one embodiment, along the height direction, a second positioning component 13 is provided between two adjacent sets of template units 021. The second positioning component 13 includes a positioning groove 131 and a second positioning member 132. The positioning groove 131 is provided on at least one end face of the opposing ends of the two adjacent sets of template units 021. The second positioning member 132 protrudes from at least one end face of the opposing ends of the two adjacent sets of template units 021 and extends into the corresponding positioning groove 131.

[0072] By setting the positioning groove 131 and the second positioning member 132, when installing two adjacent sets of template units 021, the installation position of the two sets of template units 021 can be pre-positioned along the height direction by embedding the second positioning member 132 into the positioning groove 131, ensuring their alignment accuracy in the height direction. This not only helps to accurately align the two adjacent first connecting grooves 0411, but also provides the necessary conditions for the first connecting member 05 to slide smoothly into the two adjacent first connecting grooves 0411, enabling a quick, stable and detachable connection between the two adjacent template units 021, thus improving installation efficiency.

[0073] In one embodiment of this invention, the positioning groove 131 is disposed at the bottom end of the upper template unit 021; the second positioning member 132 protrudes from the top end of the lower template unit 021 and extends into the positioning groove 131. In another embodiment of this invention, the positioning groove 131 is disposed at the top end of the lower template unit 021; the second positioning member 132 protrudes from the bottom end of the upper template unit 021 and extends into the positioning groove 131.

[0074] In specific embodiments, the shapes of the second positioning member 132 and the positioning hole 091 are not limited; the second positioning member 132 can be a rod-shaped structure and the positioning groove 131 can be a circular groove; or the second positioning member 132 can be a rectangular structure and the positioning groove 131 can be a rectangular groove.

[0075] In one embodiment, a lifting hole 011 is also included, which is located at the bottom of the casting cavity 03 and is provided on the bottom mold 01.

[0076] By setting up the lifting hole 011, the lifting rod of the lifting mechanism can extend into the casting cavity 03 through the lifting hole 011 and directly contact the bottom of the cast concrete tower piece or concrete tower cylinder, and apply an upward thrust, thereby pushing the concrete tower piece or concrete tower cylinder to rise gradually. This achieves effective separation of the concrete tower piece or concrete tower cylinder from the inner wall of the casting cavity 03, simplifies the demolding process, improves work efficiency, and ensures the integrity and quality of the concrete tower piece or concrete tower cylinder during the demolding process.

[0077] In a specific implementation, multiple lifting holes 011 are arranged at intervals along the circumferential direction, which is conducive to the uniform stress on the concrete tower sections or concrete tower cylinder and ensures the integrity of the concrete tower cylinder or concrete tower sections during the demolding process.

[0078] Preferably, multiple lifting holes 011 are provided at intervals along the radial direction, which is beneficial for demolding concrete tower sections or concrete tower cylinders of different diameters.

[0079] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
