When the concrete tower needs to be disassembled or maintained, the first connecting pieces of adjacent segments are only needed to be separated by operating the second connecting pieces, so that the disassembly of the segments can be conveniently realized, the subsequent maintenance and replacement work is facilitated, and the maintenance cost is reduced.

[0009] In an alternative embodiment, the first connecting piece has installation cavities on two sides, the installation cavities have installation openings, the installation openings of adjacent first connecting pieces correspond to each other to make the installation cavities of adjacent first connecting pieces communicate with each other, and the second connecting piece is adapted to extend into another installation cavity from one installation cavity through the installation opening to fix and connect two first connecting pieces.

[0010] Advantages: By connecting the second connecting piece with the first connecting piece, the connection stability between adjacent segments is further improved, and the overall structural strength of the concrete tower is improved. The hand hole provided on the first connecting piece not only provides an operation space for the installation of the second connecting piece, but also can be used to check and maintain the inside of the first connecting piece when needed, and the maintainability of the concrete tower is improved.

[0011] In an alternative embodiment, second abutting pieces are movably arranged on two sides of the second connecting piece, the second abutting pieces are arranged in one installation cavity, and the second connecting piece has a second matching piece that provides a biasing force for the second abutting pieces to abut against the inner wall of the installation cavity.

[0012] Beneficial effects: The second abutment abuts against the inner wall of the mounting cavity, allowing the second connector to be securely connected between the two first connectors, further enhancing the connection strength between adjacent cylinder sections. When disassembly or maintenance is required, the second connector can be easily removed by manipulating the relevant components to prevent it from abutting against the inner wall of the mounting cavity, thus separating the adjacent cylinder sections and facilitating subsequent maintenance and replacement.

[0013] In one alternative embodiment, the second connector has extensions on both sides of its bottom, the extensions being disposed within another of the mounting cavities, and a third mating member is provided between the extensions and the sidewall where the mounting port is located, the third mating member providing a biasing force to the extensions away from the sidewall where the mounting port is located.

[0014] Beneficial effects: The third fitting ensures the stability of the second connector within the mounting cavity, maintaining its position even under external stress or vibration, thus further enhancing the stability and torsional resistance of the concrete tower. This design also facilitates adjustment or replacement of the second connector when needed, improving maintenance convenience.

[0015] In one optional embodiment, the protrusion and the second connector have cavities. The protrusion and the second connector have through holes on the sidewalls of the first abutment and the second abutment. A sealing member is disposed in the cavity, and the sealing member corresponds to the through hole. One end of the first mating member extends into the through hole and abuts against the sealing member, and the other end of the first mating member abuts against the first abutment. One end of the second mating member extends into the through hole and abuts against the sealing member, and the other end of the second mating member abuts against the second abutment.

[0016] Beneficial effects: The sealing component serves to limit the movement of the first and second mating parts, preventing them from dislodging from the through hole and ensuring that the first and second abutting parts are continuously and stably subjected to bias pressure, thus maintaining contact with the inner wall of the connecting hole or the inner wall of the mounting cavity. When disassembly or replacement of the first and second mating parts is required, the sealing component can be operated to remove its limiting effect on the first and second mating parts, allowing for easy removal of the first and second mating parts for maintenance or replacement.

[0017] In one optional embodiment, a groove is provided on the inner wall of the side where the through hole is located, the sealing member is slidably connected to the groove, and the sealing member has a limiting part, which is used to limit the sealing member so that the sealing member blocks the through hole.

[0018] Beneficial effects: By incorporating a sliding connection structure between the groove and the sealing element, the sealing element can easily move within the groove, enabling rapid sealing and opening of through holes. When sealing a through hole, simply slide the sealing element along the groove to the hole position, allowing the limiting part to abut against the protrusion to complete the sealing. When opening the through hole, slide the sealing element in the opposite direction, moving it away from the hole position. This design not only improves operational convenience but also ensures the stability and reliability of the sealing process.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In related technologies, the main connection methods for concrete tower sections are through-reinforcement grouting connection and dry structural adhesive connection without grouting. Through-reinforcement grouting connection relies on long sleeves and a large number of steel bars, which makes it difficult to align the holes at high altitudes. The grouting area is small, and the grout material has poor fluidity in the confined area, making it difficult to fill densely. It requires waiting for the concrete to harden, which affects the construction period. Construction is difficult in low temperature or humid environments, and the shear strength between upper and lower sections is weak, requiring the setting of temporary support formwork, resulting in a long construction period. On the other hand, dry structural adhesive connection without grouting has high requirements for construction technology. Aging and overflow of adhesive may affect performance, and the bonding reliability and durability are difficult to guarantee. During the service stage, only the prestressed steel strands resist bending moment to prevent the sections from separating. During the construction stage, when prestressed steel strands are not installed, only the weight of the sections resist bending moment to prevent the sections from separating and overturning. For convenient transportation, segmented connection is often used. However, under the action of large torque, segmented connection is prone to segment misalignment, which leads to the concentration of principal tensile stress at the corners of the sections and the problem of dense cracks at the corners.

[0029] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0030] According to an embodiment of the present invention, a detachable self-locking toothed steel tube concrete pad beam for a mixed tower section is provided, comprising: a plurality of cylindrical sections 1 and a connecting assembly 2. Adjacent cylindrical sections 1 are fixedly connected, and each cylindrical section 1 is composed of a plurality of interconnected segments 101; the connecting assembly 2 includes connecting holes 201 and first connecting members 202. Each segment 101 has at least two connecting holes 201 on its end face facing an adjacent cylindrical section 1. The first connecting member 202 has at least two protrusions 2021, which are inserted into the connecting holes 201 to connect at least two segments 101. Movable first abutting members 2022 are provided on both sides of the protrusions 2021. Each protrusion 2021 has a first mating member 2023 that provides biasing force to the first abutting member 2022 so that the first abutting member 2022 abuts against the inner wall of the connecting hole 201.

[0031] Specifically, the top and bottom surfaces of the tube segment 101 each have two connecting holes 201, located on opposite sides of the top and bottom surfaces. The first connector 202 is a fan-shaped annular structure with the same curvature as the tube segment 101. The top or bottom end of the first connector 202 has two protrusions 2021, spaced apart, such as... Figure 1As shown, two protrusions 2021 are respectively inserted into adjacent connecting holes 201 of two adjacent tube segments 101, so that the two adjacent tube segments 101 are connected by a first connector 202. Each protrusion 2021 has a first abutment 2022 on both sides. A hinge groove (not shown) is provided on the top of the sidewall of the protrusion 2021. The two sidewalls of the hinge groove have shaft holes (not shown) for a rotating shaft (not shown) to pass through. The rotating shaft is rotatably connected to the shaft holes. One end of the first abutment 2022 is sleeved on the rotating shaft and fixedly connected to it. A first mating member 2023 is provided between the first abutment 2022 and the sidewall of the protrusion 2021. The first mating member 2023 provides biasing force to the first abutment 2022, so that after the protrusion 2021 extends into the connecting hole 201, the first abutment 2022 abuts against the inner wall of the connecting hole 201, thus fixing the protrusion 2021 within the connecting hole 201. Preferably, the first mating member 2023 is a spring. The first mating member 2023 may also be elastic rubber or other elastic elements, as long as they can provide bias pressure to make the first abutting member 2022 abut against the inner wall of the connecting hole 201.

[0032] By using the first connector 202 to connect the segments 101, compared with the traditional bent bolt connection, a larger operating space is required, the installation process is simpler, the technical requirements for installation workers are reduced, and time and labor costs are effectively saved. The first abutment 2022 can resist part of the tensile force generated by the external load bending moment through friction and pressure with the inner wall of the connection hole 201, and can effectively resist external stress. During the construction stage, it also serves as the main bending-resistant component. The first connector 202 alleviates the stress concentration at the corners of the segments 101 caused by the misalignment between the segmented segments 101, avoids the formation of corner cracks, and improves the torsional resistance of the concrete tower section 1. Furthermore, the shape of the first connector 202, the number and position of the protrusions 2021, etc., can be adjusted according to actual needs to adapt to the connection of segments 101 of different specifications and shapes. In addition, when disassembly or maintenance is required, the first connecting piece 2022 can be easily removed by operating the relevant components so that the first abutting piece 2022 is no longer in contact with the inner wall of the connecting hole 201, thereby separating the tube segment 101 and facilitating subsequent maintenance and replacement work.

[0033] In other embodiments, the first connector 202 may have four protrusions 2021. The first connector 202 can be connected to two segments 101 or three segments 101 through the four protrusions 2021. To improve the stability of the connection, three or four connection holes 201 can be provided on the end face of the segment 101. In order to connect two segments 101, the first connector 202 shall have at least two protrusions 2021.

[0034] Furthermore, such as Figure 5As shown, the two side walls of the connecting hole 201 are provided with fan-shaped grooves. After the protrusion 2021 extends into the connecting hole 201, the first abutting member 2022 enters the fan-shaped groove under the drive of the first mating member 2023 and abuts against the inner wall of the fan-shaped groove, so that the protrusion 2021 and the connecting hole 201 are engaged.

[0035] Furthermore, a rubber strip can be installed inside the fan-shaped groove to increase the friction with the first contacting member 2022.

[0036] In one embodiment, the first connecting members 202 on the opposite sides of adjacent cylindrical sections 1 are staggered, and the first connecting members 202 on the opposite sides of adjacent cylindrical sections 1 are connected to each other through the second connecting member 3 so that the adjacent cylindrical sections 1 are fixedly connected.

[0037] Specifically, such as Figure 1 As shown, the first connecting members 202 on the end face of the cylindrical section 1 are spaced apart from each other. The first connecting member 202 on the lower end face of the upper cylindrical section 1 is staggered with the first connecting member 202 on the upper end face of the lower cylindrical section 1. When the upper cylindrical section 1 and the lower cylindrical section 1 are assembled, the first connecting member 202 on the lower end face of the upper cylindrical section 1 will be inserted between the adjacent first connecting members 202 on the upper end face of the lower cylindrical section 1, so that the first connecting members 202 of the upper cylindrical section 1 and the lower cylindrical section 1 form a closed ring structure. The first connecting members 202 are connected to each other through the second connecting member 3 so that the upper cylindrical section 1 and the lower cylindrical section 1 are fixedly connected.

[0038] Adjacent sections 1 are assembled using the cooperation of the first connector 202 and the second connector 3. The assembly process is entirely dry, eliminating the need for wet methods like reinforcement and grouting, allowing for smooth construction even in winter. This ensures construction efficiency while effectively improving construction quality. Furthermore, the structural characteristics of the first connector 202 and the second connector 3 effectively resist external stresses, enhancing the overall stability and torsional resistance of the concrete tower. When the concrete tower needs disassembly or repair, simply operating the second connector 3 to separate the first connector 202 of the adjacent sections 1 facilitates disassembly of the sections, reducing maintenance and replacement costs.

[0039] In other embodiments, a third connecting hole 201 is provided on the end face of the tube segment 101. The third connecting hole 201 is located between the two connecting holes 201 on both sides. The end face of the first connecting member 202 facing the adjacent cylinder section 1 is provided with a protrusion 2021. During assembly, the protrusion 2021 of the first connecting member 202 of the lower cylinder section 1 can extend into the third connecting hole 201 of the upper cylinder section 1, so that the first connecting member 202 of the lower cylinder section 1 is also fixedly connected to the upper cylinder section 1, thereby improving the connection effect and improving the overall stability.

[0040] Furthermore, the contact area between the first connector 202 and the end face of the segment 101 is filled with sealant.

[0041] In one embodiment, the first connector 202 has mounting cavities 2024 on both sides, and the mounting cavities 2024 have mounting ports 2025. The mounting ports 2025 of adjacent first connectors 202 correspond to each other so that the mounting cavities 2024 of adjacent first connectors 202 communicate with each other. The second connector 3 is adapted to extend from one mounting cavity 2024 into another mounting cavity 2024 through the mounting ports 2025 to fix the two first connectors 202 together.

[0042] Specifically, such as Figure 3 As shown, the first connector 202 has a hand hole 2026 on its inner side facing the center of the cylindrical section 1. The hand hole 2026 communicates with the mounting cavity 2024. The second connector 3 can enter the mounting cavity 2024 through the hand hole 2026 and extend from either mounting cavity 2024 into the opposite mounting cavity 2024 to fix the two first connectors 202 together.

[0043] By connecting the second connector 3 to the first connector 202, the connection stability between adjacent cylindrical sections 1 is further enhanced, and the overall structural strength of the concrete tower is improved. The handhole 2026 opened on the first connector 202 not only provides operating space for the installation of the second connector 3, but also allows for inspection and maintenance of the interior of the first connector 202 when needed, thus improving the maintainability of the concrete tower.

[0044] In one embodiment, the second connector 3 is movably provided with second abutment members 301 on both sides, the second abutment members 301 are disposed in a mounting cavity 2024, and the second connector 3 has a second mating member 302 that provides biasing force to the second abutment members 301 so that the second abutment members 301 abut against the inner wall of the mounting cavity 2024.

[0045] Specifically, such as Figure 3 and Figure 4As shown, the top of the side wall of the second connecting member 3 is provided with a hinge groove. The two side walls of the hinge groove have shaft holes for the shaft to pass through. The shaft is rotatably connected to the shaft holes. One end of the second abutment 301 is sleeved on the shaft and fixedly connected to it. A second mating member 302 is provided between the second abutment 301 and the side wall of the second connecting member 3. The second mating member 302 provides a biasing force to the second abutment 301 so that after the second connecting member 3 extends from one mounting cavity 2024 into another mounting cavity 2024, the second abutment 301 abuts against the side wall where the mounting opening 2025 is located and the adjacent side wall at an angle. Preferably, the second abutment 301 is a spring, and the second mating member 302 can also be elastic rubber or other elastic elements, as long as they can provide a biasing force to abut the second abutment 301 against the inner wall of the mounting cavity 2024.

[0046] The second abutment 301 abuts against the inner wall of the mounting cavity 2024, allowing the second connector 3 to be securely connected between the two first connectors 202, further enhancing the connection strength between adjacent cylinder sections 1. When disassembly or maintenance is required, the second connector 3 can be easily removed by operating the relevant components to prevent the second abutment 301 from abutting against the inner wall of the mounting cavity 2024, thus separating the adjacent cylinder sections 1 and facilitating subsequent maintenance and replacement.

[0047] In one embodiment, the second connector 3 has extensions 303 on both sides of its bottom. The extensions 303 are disposed in another mounting cavity 2024. A third mating member 304 is provided between the extensions 303 and the side wall where the mounting port 2025 is located. The third mating member 304 provides the extensions 303 with a biasing force away from the side wall where the mounting port 2025 is located.

[0048] Specifically, such as Figure 3 and Figure 4 As shown, the bottom of the second connector 3 has extensions 303 protruding to both sides. The third mating member 304 is a spring. One end of the third mating member 304 is disposed on the extension 303. When the second abutment 301 extends into another mounting cavity 2024 and abuts against the side wall of the mounting cavity 2024, the other end of the third mating member 304 abuts against the side wall of the mounting cavity 2024 where it is located, which has a mounting opening 2025. The third mating member 304 applies a biasing force to the extension 303 away from the mounting opening 2025, so that the second abutment 301 always abuts against the side wall where the mounting opening 2025 is located and the adjacent side wall at the included angle.

[0049] The third mating part 304, acting on the extension 303, ensures the stability of the second connector 3 within the mounting cavity 2024. Even under external stress or vibration, its connection position remains unchanged, further enhancing the stability and torsional resistance of the concrete tower. This design also facilitates adjustment or replacement of the second connector 3 when needed, improving maintenance convenience. Furthermore, the length of the extension 303 and the elasticity of the third mating part 304 can be adjusted according to actual needs to accommodate mounting cavities 2024 of different specifications and shapes, enhancing design flexibility and applicability.

[0050] In one embodiment, the protrusion 2021 and the second connector 3 have cavities. The protrusion 2021 and the second connector 3 have through holes 6 on the side walls of the first abutment 2022 and the second abutment 301. A sealing member 4 is provided in the cavity, and the sealing member 4 corresponds to the through hole 6. One end of the first mating member 2023 extends into the through hole 6 and abuts against the sealing member 4, and the other end of the first mating member 2023 abuts against the first abutment 2022. One end of the second mating member 302 extends into the through hole 6 and abuts against the sealing member 4, and the other end of the second mating member 302 abuts against the second abutment 301.

[0051] Specifically, such as Figure 2 and Figure 4 As shown, one end of the first mating part 2023 and the second mating part 302 extends through the through hole 6 into the cavity of the protrusion 2021 and the second connecting part 3, abutting against the sealing part 4. The sealing part 4 serves to limit the first mating part 2023 and the second mating part 302, preventing them from coming out of the through hole 6, and ensuring that the first abutting part 2022 and the second abutting part 301 can be continuously and stably subjected to bias pressure, thereby maintaining abutment against the inner wall of the connecting hole 201 or the inner wall of the mounting cavity 2024. When it is necessary to disassemble or replace the first mating part 2023 and the second mating part 302, the sealing part 4 can be operated to remove it from limiting the first mating part 2023 and the second mating part 302, thereby facilitating the removal of the first mating part 2023 and the second mating part 302 for corresponding maintenance or replacement work. The sealing component 4 can take various forms, such as a screw-type sealing component 4, which can seal or open the through hole 6 by rotating the screw; or a snap-on sealing component 4, which can be operated by pressing or pulling out the snap, to meet the usage needs in different scenarios.

[0052] In one embodiment, a groove 5 is provided on the inner wall of the side where the through hole 6 is located. The sealing member 4 is slidably connected to the groove 5. The sealing member 4 has a limiting part 402, which is used to limit the sealing member 4 so that the sealing member 4 blocks the through hole 6.

[0053] Specifically, such as Figure 4As shown, the inner wall on the side where the through hole 6 is located has a pair of opposing and spaced protrusions. The groove between the pair of protrusions forms the slide groove 5. The sealing member 4 has a T-shaped structure. The vertical part of the sealing member 4 is slidably connected to the slide groove 5. The horizontal part of the sealing member 4 is the limiting part 402. After the limiting part 402 abuts against the protrusion, the sealing member 4 will block the through hole 6. The protrusion has an L-shaped structure. The vertical part of the protrusion is fixedly connected to the inner wall. The vertical part extends along the guiding direction of the inner wall. The horizontal part of the protrusion is located on the side of the vertical part away from the inner wall. The horizontal part of the protrusion extends towards the other protrusion. The horizontal part of the protrusion can close the groove and prevent the sealing member 4 from falling out of the slide groove 5.

[0054] By setting a sliding connection structure between the slide groove 5 and the sealing element 4, the sealing element 4 can easily move within the slide groove 5, enabling rapid sealing and opening of the through hole 6. When it is necessary to seal the through hole 6, simply slide the sealing element 4 along the slide groove 5 to the position of the through hole 6, so that the limiting part 402 abuts against the protrusion to complete the sealing; when it is necessary to open the through hole 6, slide the sealing element 4 in the opposite direction to move it away from the position of the through hole 6. This design not only improves the convenience of operation but also ensures the stability and reliability of the sealing. In addition, the length of the slide groove 5 and the position of the protrusion can be adjusted according to actual needs to adapt to the sealing requirements of through holes 6 of different specifications and shapes, enhancing the flexibility and applicability of the design.

[0055] In one embodiment, the sealing member 4 is provided with a handle 401, which is used to drive the sealing member 4 to move along the guide direction of the slide groove 5 under external force.

[0056] Specifically, such as Figure 4 As shown, the handle 401 is a rod-shaped structure with an anti-slip feature. One end of the handle 401 is fixedly connected to the horizontal part of the sealing component 4. When the sealing component 4 needs to be operated, the operator only needs to grasp the handle 401 and apply external force to move the sealing component 4 smoothly along the guide direction of the slide groove 5. The handle 401 greatly facilitates the operator's operation in confined spaces, improving work efficiency. Simultaneously, the anti-slip feature further enhances the grip stability of the handle 401, preventing operational errors caused by hand slippage. In practical applications, the length and shape of the handle 401 can be customized according to specific needs to adapt to different operating habits in various scenarios, thereby improving the overall practicality and user-friendliness of the design.

[0057] In one embodiment, the first connector 202 has a grouting cavity 2027, and the top surface of the first connector 202 has a grouting hole 2028 communicating with the grouting cavity 2027.

[0058] Specifically, such as Figures 1 to 3As shown, the grouting cavity 2027 is located between the two mounting cavities 2024. A grouting hole 2028 is formed on the top surface of the first connector 202, which has the end face of the protrusion 2021. The top surface of the first connector 202 has a grouting hole 2028 and a grout outlet hole. The grouting hole 2028 is located on one side of the top of the grouting cavity 2027, and the grout outlet hole is located on the other side. Grout is injected into the grouting cavity 2027 through the grouting hole 2028. When the grouting cavity 2027 is full, concrete will be discharged from the grout outlet hole. At this point, it can be determined that the grouting cavity 2027 is full of concrete, and grouting stops. It should be noted that the grouting cavity 2027 needs to be grouted before the first connector 202 is assembled.

[0059] Since the mounting cavity 2024 is a hollow cavity, the first connector 202 will bear the weight of the cylinder section after assembly. By setting the grouting cavity 2027, the concrete in the grouting cavity 2027 can provide support for the first connector 202, thereby improving the compressive strength of the first connector 202.

[0060] In one embodiment, the first connector 202 has a stiffening rib 2029, which is used to separate the grouting cavity 2027.

[0061] Specifically, such as Figure 3 As shown, stiffening ribs 2029 are installed at the connection between the grouting cavity 2027 and the installation cavity 2024, separating the grouting cavity 2027 from the installation cavity 2024. The stiffening ribs 2029 enhance the structural strength of the first connector 202, further ensuring the stability of the concrete tower. Simultaneously, the stiffening ribs 2029 also act as a barrier during grouting, preventing concrete from flowing into the installation cavity 2024.

[0062] Although embodiments of the 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 invention, and such modifications and variations all fall within the scope defined by the appended claims.
