Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, specifically to a tower structure, a wind turbine tower, and a wind turbine tower. Background Technology

[0002] In related technologies, wind turbine towers generally adopt a double-layer steel mesh structure to ensure the structural strength of the wind turbine tower. The double-layer steel mesh structure means that there are two layers of steel mesh set in the concrete of the wind turbine tower. The two layers of steel mesh are set alternately, with one layer of steel mesh close to the outer wall of the wind turbine tower and the other layer close to the inner wall of the wind turbine tower.

[0003] However, in related technologies, the two layers of steel mesh spaced apart in the double-layer steel mesh structure result in several problems. First, the internal space of some parts of the wind turbine tower becomes relatively small due to the superposition of the two layers of steel mesh and additional structures or components. This makes it difficult to ensure the accuracy of the steel bar spacing in some parts of the wind turbine tower, which can easily lead to aggregate blockage during concrete pouring, resulting in incomplete concrete compaction, voids, or weak areas. Furthermore, the steel bar binding is difficult, inefficient, and inaccurate, leading to poor structural durability and safety of the wind turbine tower. Consequently, the production quality and efficiency of the wind turbine tower are poor. Second, the wall thickness, concrete usage, steel bar usage, and weight of the wind turbine tower are all relatively large, resulting in a higher natural frequency of the wind turbine tower. Adjusting the natural frequency of the wind turbine tower to a predetermined range is difficult, and this also increases the production cost, transportation cost, and assembly difficulty of the wind turbine tower. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, this invention proposes a tower structure, a wind turbine tower, and a wind turbine tower.

[0007] The tower structure proposed in this invention, by setting the number of steel meshes inside the tower body to one, ensures the structural strength of the tower body through a single steel mesh. On the one hand, it increases the space for additional structures or components inside the tower body, making it easier to ensure the accuracy of the spacing of the steel bars inside the tower body. This reduces or even avoids aggregate blockage during concrete pouring, which in turn facilitates concrete compaction and reduces or even avoids the formation of voids or weak areas inside the tower body. Furthermore, it reduces the difficulty, increases efficiency, and improves the accuracy of steel bar binding, thereby improving the structural durability and safety of the tower structure, and enhancing the production quality and efficiency of the tower structure. On the other hand, it reduces the wall thickness, concrete usage, steel bar usage, and weight of the tower body, thereby lowering the natural frequency of the tower structure and reducing the difficulty of adjusting the natural frequency of the tower structure to a predetermined range. It also reduces the production cost, transportation cost, and assembly difficulty of the tower structure.

The curved doorway ribs and a portion of the horizontal doorway ribs are located at the top of the doorway, and another portion is located at the bottom of the doorway. The hoop doorway ribs connect the horizontal doorway ribs, vertical doorway ribs, diagonal doorway ribs, and curved doorway ribs to the steel mesh. And / or, the reinforcing ribs provided on the portion of the tower body corresponding to the hoisting component include additional longitudinal ribs and additional ring ribs, wherein the additional longitudinal ribs and the additional ring ribs are arranged intersectingly; And / or, the reinforcing ribs provided on the portion of the tower body corresponding to the longitudinal connecting component and the longitudinal connecting channel include additional longitudinal ribs and additional ring ribs, and the additional longitudinal ribs and the additional ring ribs are arranged intersectingly; And / or, the reinforcing ribs provided on the portion of the tower body corresponding to the circumferential end include end longitudinal ribs and end stirrups, the end longitudinal ribs and the end stirrups are arranged intersectingly, and the end stirrups connect the end longitudinal ribs to the steel mesh; And / or, the reinforcing ribs provided on the portion of the tower body corresponding to the transverse connecting channel include bent bolt reinforcing bars, which surround the transverse connecting channel.

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The following is for reference. Figures 1-8 The present invention describes a tower structure, a wind turbine tower, and a wind turbine tower according to embodiments thereof.

[0023] like Figures 1-8 As shown, the tower structure of this embodiment of the invention includes a tower body 1 and a steel reinforcement structure.

[0024] The steel reinforcement structure is set inside the main body 1 of the tower. The steel reinforcement structure includes a steel mesh 2, and the number of steel mesh 2 is one.

[0025] The tower structure proposed in this embodiment of the invention, by setting the number of steel mesh 2 inside the tower body 1 to one, ensures the structural strength of the tower body 1 through a single steel mesh 2. On the one hand, it can increase the space inside the tower body 1 where additional structures or components are set, making it easier to ensure the accuracy of the spacing of the steel bars inside the tower body 1, thereby reducing or even avoiding aggregate blockage during concrete pouring, which in turn facilitates concrete vibration and compaction, reducing or even avoiding the formation of voids or weak areas inside the tower body 1. Furthermore, it reduces the difficulty of steel bar binding, improves efficiency and accuracy, thereby improving the structural durability and safety of the tower structure, and improving the production quality and efficiency of the tower structure. On the other hand, it can reduce the wall thickness, concrete usage, steel bar usage and its own weight of the tower body 1, thereby reducing the natural frequency of the tower structure, reducing the difficulty of adjusting the natural frequency of the tower structure to a predetermined range, and reducing the production cost, transportation cost and assembly difficulty of the tower structure.

[0026] like Figure 1 and Figure 2 As shown, optionally, the steel mesh 2 may include longitudinal bars 21 and ring bars 22. The longitudinal bars 21 may extend along the axial direction of the tower body 1, and the ring bars 22 may extend along the circumferential direction of the tower body 1.

[0027] Optionally, the tower body 1 can be annular or polygonal. In this case, the tower structure can be a tower segment.

[0028] Optionally, the tower body 1 can be arc-shaped or bent. Multiple arc-shaped tower bodies 1 can be combined to form a ring, and multiple bent tower bodies 1 can be combined to form a polygon. In this case, the tower structure can be segmented.

[0029] In practical applications, the shape of the reinforcing mesh 2 can be adapted to the shape of the tower body 1. For example, when the tower body 1 is arc-shaped, the reinforcing mesh 2 can also be arc-shaped, and the ring reinforcement 22 can also be arc-shaped; when the tower body 1 is ring-shaped, the reinforcing mesh 2 can also be ring-shaped, and the ring reinforcement 22 can also be ring-shaped. However, the shape of the reinforcing mesh 2 is not limited to adapting to the shape of the tower body 1. The shape of the reinforcing mesh 2 can also not adapt to the shape of the tower body 1. For example, when the tower body 1 is bent, the reinforcing mesh 2 can also be arc-shaped, and the ring reinforcement 22 can also be arc-shaped; when the tower body 1 is polygonal, the reinforcing mesh 2 can also be ring-shaped, and the ring reinforcement 22 can also be ring-shaped.

[0030] In one embodiment of the present invention, the material of the tower body 1 may include ultra-high performance concrete.

[0031] Ultra-high performance concrete (UHPC) is a material with ultra-high strength.

[0032] During the research process, the inventors of this invention studied tower structures with ultra-high performance concrete without steel mesh, tower structures with high-strength concrete (HSC) with double-layer steel mesh (i.e., two steel meshes are set inside the tower body), and tower structures with ultra-high performance concrete with single-layer steel mesh (i.e., one steel mesh is set inside the tower body 1) proposed in the embodiments of this invention.

[0033] For tower structures constructed with ultra-high performance concrete (UHVPC) without reinforcing mesh, two main challenges arise: firstly, the principal tensile stress is high, leading to weak tensile strength; secondly, the natural frequencies (including first and second-order frequencies) are high, meaning the lower limit of the natural frequency is high. Adjusting the natural frequency to a predetermined range (not necessarily higher or lower, but rather in harmony with components like the wind turbine) presents significant challenges. The inventors of this invention have discovered that by incorporating a reinforcing mesh 2 within the UHVPC, the principal tensile stress of the tower structure can be altered. The mesh 2 primarily provides the tensile strength of the tower structure, minimizing the impact of the UHVPC on its tensile properties. Therefore, by including the reinforcing mesh 2 within the UHVPC tower structure, the principal tensile stress can be reduced, enhancing the tensile strength. Furthermore, while meeting the principal compressive stress requirements (i.e., satisfying the compressive strength requirements), the amount of UHVPC used to reduce the principal tensile stress can be reduced. The amount and grade of ultra-high performance concrete used can be reduced, thereby reducing the wall thickness of the tower body 1, the amount of ultra-high performance concrete used, and the cost. This can reduce the production cost, transportation cost, and assembly difficulty of the tower structure. On the other hand, it was found that by setting steel mesh 2 in ultra-high performance concrete, the wall thickness of the tower body 1 can be reduced, which can lower the natural frequency of the tower structure. In other words, the lower limit of the natural frequency of the tower structure can be lowered. This allows the natural frequency of the tower structure to be adjusted based on the lower limit of the natural frequency, making it easier to adjust the natural frequency of the tower structure to the predetermined range. In other words, it reduces the difficulty of adjusting the natural frequency of the tower structure to the predetermined range.

[0034] For tower structures using high-strength concrete and double-layer steel mesh, the technical problems pointed out in the background section of this invention exist. The inventors of this invention, through research, have discovered that by setting a single steel mesh 2 within the ultra-high-performance concrete, the technical problems pointed out in the background section can be solved. This improves the structural durability and safety of the tower body 1, enhances the production quality and efficiency of wind turbine towers, and reduces the wall thickness of the tower body 1, thereby lowering the natural frequency of the tower structure. In other words, the lower limit of the natural frequency of the tower structure can be lowered, allowing for adjustment of the natural frequency based on this lower limit. This makes it easier to adjust the natural frequency of the tower structure to a predetermined range, reducing the difficulty of adjusting the natural frequency of the tower structure to a predetermined range, and also reducing the production cost, transportation cost, and assembly difficulty of wind turbine towers.

[0035] Therefore, it can be seen that the tower structure of the present invention, which is a combination of ultra-high performance concrete and single-layer steel mesh, proposed by the inventors of the present invention through research, forms the tower body 1 by using ultra-high performance concrete and a single steel mesh 2. By taking advantage of the characteristics of ultra-high performance concrete itself, a single steel mesh 2 can more easily ensure the structural strength of the tower body 1. Furthermore, on the basis of ensuring the structural strength of the tower body 1, it is also beneficial to adjust the principal tensile stress and natural frequency of the tower structure.

[0036] In practical applications, the wall thickness of a tower structure with high-strength concrete and double-layer steel mesh may be greater than 300mm, while the wall thickness of a tower structure with ultra-high performance concrete and single-layer steel mesh proposed in this embodiment of the invention can be reduced to about 170mm. This situation results in the concrete usage of the tower structure with high-strength concrete and double-layer steel mesh being more than 30% higher than that of the tower structure with ultra-high performance concrete and single-layer steel mesh proposed in this embodiment of the invention.

[0037] In one embodiment of the present invention, the diameter of the reinforcing bars in the reinforcing mesh 2 can be 8mm to 12mm.

[0038] In practical applications, by increasing or decreasing the diameter of the steel bars in the steel mesh 2, the reinforcement ratio of the tower body 1 can be increased or decreased, thereby adjusting the reinforcement ratio of the tower body 1 to meet the requirements and satisfy the structural strength requirements of the tower structure.

[0039] Optionally, the diameter of the reinforcing bars in the reinforcing mesh 2 can be 8mm or 10mm.

[0040] In one embodiment of the present invention, the spacing between the steel bars of the steel mesh 2 can be 75mm to 100mm.

[0041] In practical applications, by increasing or decreasing the spacing of the steel bars in the steel mesh 2, the reinforcement ratio of the tower body 1 can be increased or decreased, thereby adjusting the reinforcement ratio of the tower body 1 to meet the requirements and satisfy the structural strength requirements of the tower structure.

[0042] Optionally, the spacing of the reinforcing bars in the reinforcing mesh 2 can be 75mm.

[0043] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the distance between the steel mesh 2 and the outer wall of the tower body 1 can be smaller than the distance between the steel mesh 2 and the inner wall of the tower body 1.

[0044] In other words, the steel mesh 2 located between the inner and outer walls of the tower body 1 is closer to the outer wall of the tower body 1 and farther away from the inner wall. Since the tensile force borne by the outer part of the tower body 1 near the outer wall is greater than that borne by the inner part of the tower body 1 near the inner wall, by setting the steel mesh 2 close to the outer wall of the tower body 1, that is, setting the steel mesh 2 on the outer part of the tower body 1 near the outer wall, the circumferential length of the steel mesh 2 can be longer and the coverage area can be larger. This can increase the tensile strength provided by the steel mesh 2 to the tower structure, making it easier for a steel mesh 2 to ensure the structural strength of the tower body 1. Furthermore, on the basis of ensuring the structural strength of the tower body 1, it is also beneficial to the principal tensile stress of the tower structure.

[0045] like Figure 2 As shown, in one embodiment of the present invention, the steel reinforcement structure may further include reinforcing bars 3, which are disposed in a portion of the steel mesh 2.

[0046] In practical applications, reinforcing ribs 3 can be installed at stress concentration points in the tower body 1. These stress concentration points are more prone to damage than other parts of the tower body 1. By installing reinforcing ribs 3 at these stress concentration points, the structural strength of the tower body 1 can be reinforced, reducing or even preventing damage at these points. The reinforcing ribs 3 can be connected to the reinforcing mesh 2; that is, the reinforcing ribs 3 are placed locally within the reinforcing mesh 2. This combination of reinforcing ribs 3 and reinforcing mesh 2 further improves the structural durability and safety of the tower body 1, enhances production quality and efficiency, and makes it easier for the reinforcing mesh 2 to ensure the structural strength of the tower body 1 and the overall tower structure.

[0047] Furthermore, since the tower body 1 of the tower structure proposed in this embodiment of the invention has only one steel mesh 2 inside, the interior of the tower body 1 can have a large space for the reinforcing ribs 3. This allows for the design of larger reinforcing ribs 3, thereby increasing their ability to strengthen the structure of the tower body 1. On the other hand, during the process of building the steel structure before pouring concrete to form the tower body 1, even if the reinforcing ribs 3 are large, the connection (e.g., binding) between the reinforcing ribs 3 and the steel mesh 2 can be made easier, more efficient, and more accurate, thus improving the structural durability and safety of the tower body 1, as well as the production quality and efficiency of the tower body 1. Moreover, it makes it easier to ensure the accuracy of the spacing between the reinforcing ribs 3 and the steel mesh 2, thereby reducing or even avoiding aggregate blockage during concrete pouring, which is beneficial for concrete compaction and reduces or even avoids the formation of voids or weak areas inside the tower body 1, thus improving the structural durability and safety of the tower body 1 and the production quality of the tower body 1.

[0048] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the reinforcing rib 3 can be close to the inner wall of the tower body 1 relative to the steel mesh 2.

[0049] In other words, the steel mesh 2 is closer to the outer wall of the tower body 1 than the reinforcing rib 3. This allows the steel mesh 2 to be closer to the outer wall of the tower body 1, resulting in a longer circumferential length and a larger coverage area. This increases the tensile strength provided by the steel mesh 2 to the tower structure and provides more complete space for the reinforcing rib 3. Consequently, the steel mesh 2 can more easily ensure the structural strength of the tower body 1, and in addition to ensuring the structural strength of the tower body 1, it is also beneficial to the principal tensile stress of the tower structure. Furthermore, it reduces the difficulty, increases efficiency, and improves the accuracy of connecting the reinforcing rib 3 and the steel mesh 2, thereby improving the production quality and efficiency of the tower body 1. This reduces or even avoids aggregate blockage during concrete pouring, promotes concrete compaction, reduces or even avoids the formation of voids or weak areas inside the tower body 1, improves the structural durability and safety of the tower body 1, and enhances the production quality of the tower body 1.

[0050] like Figure 6 As shown, in one embodiment of the present invention, the reinforcing rib 3 may be in the form of a ring or the reinforcing rib 3 and the steel mesh 2 may be partially together to form a ring.

[0051] In other words, the reinforcing rib 3 itself can be in a ring shape, or the reinforcing rib 3 itself is not in a ring shape, but is connected locally with the steel mesh 2 in a ring shape, thereby improving the structural strength of the reinforcing rib 3, improving the local structural strength of the steel mesh 2, and thus increasing the reinforcing rib 3's ability to strengthen the structural strength of the tower body 1.

[0052] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the tower body 1 may have at least one of the following: a doorway 11, a hoisting component 12, a longitudinal connecting component 13, a longitudinal connecting channel 14 through which the longitudinal connecting component 13 passes, a circumferential end, and a transverse connecting channel 15 disposed at the circumferential end. The portion of the tower body 1 corresponding to at least one of the following: doorway 11, hoisting component 12, longitudinal connecting component 13, longitudinal connecting channel 14, circumferential end, and transverse connecting channel 15 is provided with reinforcing ribs 3.

[0053] The doorway 11 is used for personnel to enter and exit the wind turbine tower formed by the tower structure, so that they can enter the wind turbine tower to carry out assembly operations during the wind turbine tower assembly process, such as installing anchors for connecting connected wind turbine towers, and can enter the wind turbine tower for inspection and maintenance after the wind turbine tower is assembled.

[0054] The lifting component 12 is used to connect with lifting equipment such as tower cranes and hoists to lift the tower structure and the wind turbine tower formed by the tower structure, so as to facilitate the movement and assembly of the tower structure and the wind turbine tower.

[0055] The longitudinal connecting component 13 is used to connect to the longitudinal connecting channel 14 of another tower structure that is longitudinally adjacent, thereby connecting and positioning the two adjacent tower structures in the longitudinal direction.

[0056] The transverse connecting channel 15 is used to be opposite to the transverse connecting channel 15 of another circumferentially adjacent arc-shaped or bent tower structure and to pass through transverse connecting components such as bent bolts, so as to connect and position the two circumferentially adjacent arc-shaped or bent tower structures through transverse connecting components such as bent bolts.

[0057] In practical applications, stress concentrations are easily generated at the doorway 11, hoisting component 12, longitudinal connecting component 13, longitudinal connecting channel 14, circumferential end, and transverse connecting channel 15 of the tower body 1. By setting reinforcing ribs 3 in at least one of the corresponding parts of the tower body 1, such as the doorway 11, hoisting component 12, longitudinal connecting component 13, longitudinal connecting channel 14, circumferential end, and transverse connecting channel 15, the structural strength of the tower body 1 can be reinforced by the reinforcing ribs 3.

[0058] Optionally, the lifting component 12 can be a lifting nail pre-embedded in the tower body 1 and spaced apart along the circumference of the tower body 1.

[0059] Optionally, the longitudinal connecting component 13 can be a reinforcing bar pre-embedded in the tower body 1 and spaced apart along the circumference of the tower body 1.

[0060] Optionally, the interior of the tower body 1 may be provided with pre-embedded pipes such as corrugated pipes along the longitudinal direction, and the internal channels of the pre-embedded pipes along the longitudinal direction can be used as longitudinal connecting channels 14.

[0061] Optionally, the lateral connecting component can be a bent bolt inserted into two adjacent and connected lateral connecting holes 15.

[0062] Optionally, the interior of the tower body 1 may be provided with a circumferentially embedded bent bolt pre-embedded pipe, and the internal channel of the bent bolt pre-embedded pipe may serve as a transverse connection channel 15. The inner wall of the tower body 1 may further be provided with a manhole box communicating with the bent bolt pre-embedded pipe, and the internal channel of the manhole box and the internal channel of the bent bolt pre-embedded pipe may jointly serve as a transverse connection channel 15.

[0063] like Figures 1-8 As shown, in one embodiment of the present invention, the reinforcing ribs 3 provided on the part of the tower body 1 corresponding to the door opening 11 may include door opening horizontal ribs 31, door opening longitudinal ribs 32, door opening diagonal ribs 33, door opening arc ribs 34 and door opening stirrups 35.

[0064] The longitudinal reinforcement 32 of the door opening can be provided at the top, bottom, and both sides of the door opening 11, and can be arranged in multiple spaced intervals along the transverse direction of the door opening 11. A portion of the diagonal reinforcement 33 can extend from the side of the door opening 11 to the top of the door opening 11, optionally located at the two top corners of the door opening 11; another portion of the diagonal reinforcement 33 can extend from the side of the door opening 11 to the bottom of the door opening 11, optionally located at the two bottom corners of the door opening 11. The curved reinforcement 34 and a portion of the horizontal reinforcement 31 of the door opening can be provided at the top of the door opening 11. The curved reinforcement 34 can be arranged parallel to the curved edge of the top of the door opening 11, and the horizontal reinforcement 31 can be arranged in multiple spaced intervals along the longitudinal direction of the door opening 11. Another portion of the horizontal reinforcement 31 of the door opening can be provided at the bottom of the door opening 11, and can also be arranged in multiple spaced intervals along the longitudinal direction of the door opening 11. Therefore, the horizontal reinforcement 31, vertical reinforcement 32, diagonal reinforcement 33, and curved reinforcement 34 of the doorway can be arranged in a grid pattern around the doorway 11. The doorway stirrups 35 can be attached to adjacent horizontal reinforcement 31, vertical reinforcement 32, diagonal reinforcement 33, and curved reinforcement 34, and can be connected to the steel mesh 2. This reduces or even avoids the possibility of separation or movement of the grid-like horizontal reinforcement 31, vertical reinforcement 32, diagonal reinforcement 33, and curved reinforcement 34 during the pouring process, which could lead to deformation of the doorway 11. The installation of the doorway stirrups 35 allows the reinforcing ribs 3 to form a ring shape, thereby improving the structural strength of the reinforcing ribs 3 and increasing their ability to reinforce the structural strength of the tower body 1.

[0065] In practical applications, the horizontal reinforcement 31 of the doorway can be along the transverse direction of the main body 1 of the tower (e.g., Figure 1 It extends in the horizontal direction shown, but not in the circumferential direction of the tower body 1.

[0066] like Figure 1 , Figure 2 and Figure 7 As shown, in one embodiment of the present invention, the reinforcing ribs 3 provided on the part of the tower body 1 corresponding to the hoisting component 12 may include additional longitudinal ribs 36 and additional ring ribs 37, and the additional longitudinal ribs 36 and additional ring ribs 37 may be arranged crosswise.

[0067] In practical applications, the additional ring reinforcement 37 can be arranged in multiple spaced intervals along the longitudinal direction. The additional ring reinforcement 37 can be Ω-shaped so that multiple additional ring reinforcement 37 form a receiving space. At least two additional longitudinal reinforcements 36 can be connected to the portion of the receiving space formed by multiple additional ring reinforcements 37 to form a grid. The hoisting component 12 can be located in the receiving space formed by the additional longitudinal reinforcement 36 and the additional ring reinforcement 37, so as to be surrounded by the reinforcing rib 3 and the steel mesh 2. The additional ring reinforcement 37 can be tied to the steel mesh 2. In this structure, the reinforcing rib 3 and the steel mesh 2 can jointly form a ring, thereby improving the structural strength of the reinforcing rib 3, and thus increasing the reinforcing ability of the reinforcing rib 3 to strengthen the structural strength of the tower body 1.

[0068] like Figure 1 , Figure 2 and Figure 7 As shown, in one embodiment of the present invention, the reinforcing ribs 3 provided on the part of the tower body 1 corresponding to the longitudinal connecting component 13 and the longitudinal connecting channel 14 may include additional longitudinal ribs 36 and additional ring ribs 37, and the additional longitudinal ribs 36 and additional ring ribs 37 may be arranged crosswise.

[0069] In practical applications, the longitudinal connecting component 13 may be located within the receiving space formed by the additional longitudinal reinforcement 36 and the additional ring reinforcement 37, so as to be surrounded by the corresponding reinforcing ribs 3 and steel mesh 2. The internal channel, as the longitudinally arranged embedded pipe of the longitudinal connecting channel 14, may be located within the receiving space formed by the additional longitudinal reinforcement 36 and the additional ring reinforcement 37, so as to be surrounded by the corresponding reinforcing ribs 3 and steel mesh 2. The longitudinal connecting component 13 and the longitudinal connecting channel 14 may be located at the top of the tower body 1 and at the bottom of the tower body 1, respectively.

[0070] In practical applications, the additional ring reinforcement 37 itself does not have to be ring-shaped, but can extend along the circumference of the tower body 1.

[0071] like Figure 1 , Figure 2 and Figure 7 As shown, in one embodiment of the present invention, the reinforcing ribs 3 provided on the part corresponding to the circumferential end of the tower body 1 may include end longitudinal ribs 38 and end stirrups 39. The end longitudinal ribs 38 and end stirrups 39 are arranged intersectingly, and the end stirrups 39 connect the end longitudinal ribs 38 to the steel mesh 2.

[0072] In practical applications, the end stirrups 39 can be selected as multiple longitudinal bars 38 spaced apart along the end longitudinal bars 38, and the end longitudinal bars 38 can be selected as multiple circumferentially spaced along the end stirrups 39, arranged in a cross pattern to form a reinforcing cage. They can be connected to the reinforcing mesh 2 through the end stirrups 39, thereby reducing or even avoiding the separation of the end longitudinal bars 38 and end stirrups 39 during the casting process, as well as the circumferential deformation caused by movement. In this structure, the reinforcing bars 3 and the reinforcing mesh 2 can jointly form a ring, thereby improving the structural strength of the reinforcing bars 3 and increasing their ability to reinforce the structural strength of the tower body 1.

[0073] like Figure 1 , Figure 2 and Figure 7 As shown, in one embodiment of the present invention, the reinforcing ribs 3 provided on the part of the tower body 1 corresponding to the transverse connecting channel 15 may include bent bolt reinforcing bars 310.

[0074] In practical applications, the bent bolt reinforcing steel bar 310 can be spiral-shaped and wrapped around the outside of the transverse connecting channel 15. In other words, the spiral-shaped bent bolt reinforcing steel bar 310 can wrap around the bent bolt embedded pipe of the internal channel serving as the transverse connecting channel 15. By setting the spiral-shaped bent bolt reinforcing steel bar 310, the reinforcing rib 3 itself can be made into a ring shape, thereby improving the structural strength of the reinforcing rib 3 and thus increasing the reinforcing ability of the reinforcing rib 3 to strengthen the structural strength of the tower body 1.
