Description

Technical Field

[0001] This application relates to the field of concrete tower technology, specifically to a concrete tower. Background Technology

[0002] In related technologies, concrete towers are mainly constructed using a segmented prefabrication and on-site assembly process. The vertical joints between adjacent segments are typically connected using bolts and epoxy resin adhesive. However, this vertical joint connection method suffers from the problem of high dispersion in the bonding strength between the epoxy resin adhesive and the concrete (some areas are very firmly bonded, while others are very weakly bonded). During construction, the bolt pre-tightening force can easily cause warping stress between the segments due to angular deviations, reducing the torsional resistance of the concrete tower. Utility Model Content

[0003] This application provides a concrete tower that can improve the shear and torsional bearing capacity of the concrete tower.

[0004] To achieve the above objectives, the embodiments of this application disclose the following technical solutions: This application provides a concrete tower, including multiple first segments and connecting plates; the multiple first segments are distributed in a preset direction; each of the end faces of two adjacent first segments facing each other has an assembly groove, the assembly groove extending to the inner circumferential surface of the first segment; a reinforcing plate is embedded in the first segment, and a portion of the reinforcing plate is exposed at the groove wall of the corresponding first segment's assembly groove; the reinforcing plates of two adjacent first segments are fixedly connected by a connecting plate, and the connecting plate is located in the assembly groove corresponding to the reinforcing plates of the two adjacent first segments.

[0005] This configuration, by exposing a portion of the reinforcing plate embedded within the first segment at the wall of the corresponding assembly slot, allows the reinforcing plates of adjacent first segments to be fixedly connected at the assembly slot via connecting plates. This directly transfers the connection load between the first segments to the reinforcing plate, which, through its bond and anchoring with the concrete, distributes the load more evenly throughout the segment. Consequently, when the reinforcing plate and connecting plate are bolted together, this reduces the warping stress on the segment caused by the bolt preload, thereby improving the shear and torsional bearing capacity of the concrete tower.

[0006] Furthermore, since each of the two adjacent first tube segments has an assembly groove on its end face facing each other, these grooves can communicate with each other. This allows the connecting plate to be accommodated within the space formed by the assembly grooves of the two adjacent first tube segments. This prevents interference between the connecting plate and other equipment inside the concrete tower, thereby improving the reliability of the concrete tower.

[0007] In addition, since epoxy resin adhesive is not used in the fixed connection between two adjacent first segments, stress concentration caused by the high dispersion of the bond strength between epoxy resin adhesive and concrete can be effectively avoided, which is conducive to improving the shear and torsional bearing capacity of the concrete tower.

[0008] In some possible implementations, an extension plate protrudes from the surface of the reinforcing plate exposed on the wall of the assembly slot. The reinforcing plates of two adjacent first segments are fixedly connected to the connecting plates by means of corresponding extension plates.

[0009] In some possible implementations, the assembly slot has a first slot located on the inner circumferential surface of the first segment; the connecting plate is located on the side of the extension plate opposite to the first slot.

[0010] In some possible implementations, reinforcing plates protrude from both ends of the connecting plate.

[0011] In some possible implementations, the connecting plate is welded to the extension plate, and the extension plate is welded to the reinforcing plate.

[0012] In some possible implementations, the connecting plate is spaced apart from the wall of the assembly slot; and / or, In each first segment, there are multiple assembly slots, with the multiple assembly slots located at the same end of the first segment arranged at intervals; and / or, Anchor bars are embedded in the first segment, and the anchor bars are fixedly connected to the reinforcing plate.

[0013] In some possible implementations, multiple first reinforcing ribs are embedded inside the interior of the adjacent ends of two adjacent first segments.

[0014] In some possible implementations, first stirrups are embedded inside the interior of the adjacent ends of two adjacent first segments; Among the multiple first reinforcing ribs and first stirrups at one end of the same first segment, the first stirrups are fixed to the outer periphery of the multiple first reinforcing ribs.

[0015] In some possible implementations, a plurality of second reinforcing ribs are embedded in the first segment, and the plurality of second reinforcing ribs are located on one side of the first segment’s own assembly groove near the middle of the first segment.

[0016] In some possible implementations, a second stirrup is embedded in the first segment, and a second stirrup is fixed to the outer periphery of a plurality of second reinforcing ribs.

[0017] In some possible implementations, the preset direction includes the circumferential direction of the concrete tower and / or the axial direction of the concrete tower. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Any embodiment or design described as "exemplarily" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0026] In the description of the embodiments of this application, the term "multiple" means two or more.

[0027] In the description of the embodiments of this application, the term "and / or" refers to and covers any and all possible combinations of one or more of the associated listed items. The term "and / or" describes an association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "or" relationship.

For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0030] In related technologies, concrete tower sections are mainly constructed using a segmented prefabrication and on-site assembly process. Vertical joints between adjacent sections are typically connected using bolts and epoxy resin adhesive. Specifically, the assembly method between adjacent sections and bolts involves threaded holes on the end faces of two adjacent sections facing each other, with the bolts simultaneously screwed into these holes. Because the concrete tower sections are curved, the bolt pre-tightening force during construction can easily cause warping stress between sections due to angular deviations in the threaded holes, reducing the torsional resistance of the concrete tower.

[0031] In addition, the bonding strength between epoxy resin adhesive and concrete is highly variable (it is very strong in some places and very weak in others), making it difficult to ensure uniform and stable connection quality and easily causing stress concentration problems.

[0032] For the above technical issues, please refer to Figure 1 and combined Figure 2 ,in, Figure 1 This application provides a structural schematic diagram of a concrete tower 100 according to some embodiments; Figure 2 for Figure 1 The image shows an enlarged view of the portion of the concrete tower 100 circled at point A. This application provides a concrete tower 100, which is applicable to, but not limited to, wind turbines. The concrete tower 100 includes a plurality of first segments 1 and connecting plates 2. It is understood that... Figure 1 and Figure 2The accompanying drawings below only schematically illustrate some of the components included in the concrete tower 100. The actual shape, size, location, and construction of these components are not subject to change. Figure 1 and Figure 2 As well as the limitations of the accompanying figures below.

[0033] Multiple first segments 1 are distributed according to a preset direction. This preset direction includes the circumferential direction of the concrete tower 100 and / or the axial direction of the concrete tower 100. As an example, in... Figure 1 The preset direction of the embodiment shown is the circumferential direction of the concrete tower 100.

[0034] Each of two adjacent first tube segments 1 has an assembly groove 11 on its end face facing each other, and the assembly groove 11 extends through to the inner circumferential surface of the first tube segment 1. That is, the assembly groove 11 has a first slot 111 located on the inner circumferential surface of the first tube segment 1 and a second slot 112 located on the end face of the first tube segment 1 facing the other first tube segment 1. The first slot 111 and the second slot 112 are connected.

[0035] A reinforcing plate 12 is embedded within the first segment 1, and a portion of the reinforcing plate 12 is exposed at the groove wall of the corresponding assembly groove 11 of the first segment 1. For example, a portion of the reinforcing plate 12 may be exposed at the bottom wall of the corresponding assembly groove 11 of the first segment 1, or a portion of the reinforcing plate 12 may be exposed at the side wall of the corresponding assembly groove 11 of the first segment 1. As an example, in Figure 2 In the embodiment shown, a portion of the reinforcing plate 12 may be exposed at the bottom wall of the mounting groove 11 of the corresponding first tube segment 1.

[0036] The reinforcing plates 12 of two adjacent first tube segments 1 are fixedly connected by a connecting plate 2, and the connecting plate 2 is located in the assembly groove 11 corresponding to the reinforcing plates 12 of the two adjacent first tube segments 1.

[0037] This configuration, by exposing a portion of the reinforcing plate 12 embedded within the first segment 1 at the corresponding assembly groove 11 wall, allows the reinforcing plates 12 of adjacent first segments 1 to be fixedly connected at the assembly groove 11 via the connecting plate 2. This allows the connection load between the first segments 1 to be directly transferred to the reinforcing plate 12, which, through its bonding and anchoring with the concrete, distributes the connection load more evenly throughout the segment. Consequently, when the reinforcing plate 12 is bolted to the connecting plate 2, it helps to reduce the warping stress on the segment caused by the bolt preload, thereby improving the shear and torsional bearing capacity of the concrete tower 100.

[0038] Furthermore, since each of the two adjacent first tube segments 1 has an assembly groove 11 on its end face facing each other, the assembly grooves 11 on the two adjacent first tube segments 1 can communicate with each other. Therefore, the connecting plate 2 can be accommodated within the space formed by the assembly grooves 11 of the two adjacent first tube segments 1. This prevents the connecting plate 2 from interfering with other equipment inside the concrete tower 100, thereby improving the reliability of the concrete tower 100.

[0039] In addition, since epoxy resin adhesive is not used in the fixed connection between the two adjacent first segments 1, stress concentration caused by the high dispersion of the bond strength between epoxy resin adhesive and concrete can be effectively avoided, which is conducive to improving the shear and torsional bearing capacity of the concrete tower 100.

[0040] It is necessary to clarify that, since the preset direction includes the circumferential direction of the concrete tower 100 and / or the axial direction of the concrete tower 100, the two adjacent first segments 1 mentioned above can be two adjacent first segments 1 in the circumferential direction of the concrete tower 100, or two adjacent first segments 1 in the axial direction of the concrete tower 100. Thus, it can be understood that in some embodiments, each segment of the concrete tower 100 can be a first segment 1. In other embodiments, some segments of the concrete tower 100 can also be first segments 1, that is, the concrete tower 100 can also include second segments, third segments, etc., with structures different from the first segments 1.

[0041] Furthermore, it is worth noting that when two adjacent first segments 1 in the circumferential direction of the concrete tower 100 form a ring, or when one first segment 1 is located between two other first segments 1 in the circumferential direction of the concrete tower 100, and the preset direction includes the circumferential direction of the concrete tower 100, both end faces of that first segment 1 in the circumferential direction of the concrete tower 100 have assembly grooves 11. Similarly, when one first segment 1 is located between two other first segments 1 in the axial direction of the concrete tower 100, and the preset direction includes the axial direction of the concrete tower 100, both end faces of that first segment 1 in the axial direction of the concrete tower 100 have assembly grooves 11.

[0042] Please see Figure 2In some embodiments, an extension plate 13 protrudes from the surface of the reinforcing plate 12 exposed on the wall of the assembly slot 11; the reinforcing plates 12 of two adjacent first tube segments 1 are fixedly connected to the connecting plate 2 by means of the corresponding extension plates 13. In this way, a more ample and clear assembly area is provided for the fixed connection between the connecting plate 2 and the reinforcing plate 12, so that adjacent first tube segments 1 have a larger tolerance space and a more easily operable positioning reference when docking, thereby effectively reducing the alignment difficulty of on-site assembly and improving the convenience and reliability of assembly operations.

[0043] Please see Figure 3 , Figure 3 for Figure 2 The diagram shows the assembly of the connecting plate 2, the extension plate 13, and the reinforcing plate 12 in the structure shown. In some embodiments, the connecting plate 2 is located on the side of the extension plate 13 opposite to the first slot 111. This allows the operator to observe and operate the extension plate 13 without obstruction for fixed connection. This improves the ease of operation and assembly efficiency during the assembly of the concrete tower 100 segments. Of course, this application is not limited to this. In other embodiments, the connecting plate 2 may also be located on the side of the extension plate 13 closer to the slot.

[0044] Please see Figure 2 and combined Figure 3 In some embodiments, reinforcing plates 21 protrude from both ends of the connecting plate 2. This increases the cross-sectional dimensions of the ends of the connecting plate 2, thereby increasing the section modulus of the connecting plate 2. This enhances the connecting plate 2's resistance to bending deformation, thereby improving the overall structural stability and torsional resistance of the concrete tower 100.

[0045] For example, the connecting plate 2 has reinforcing plates 21 protruding from both ends of the concrete tower cylinder 100 in the axial direction. In this case, the reinforcing plates 21 can protrude towards the side of the connecting plate 2 closer to the extension plate 13, or they can protrude towards the side of the connecting plate 2 away from the extension plate 13. As an example, in... Figure 2 In the embodiment shown, the reinforcing plate 21 protrudes toward the side of the connecting plate 2 near the extension plate 13.

[0046] Of course, this application is not limited to this. Alternatively, the connecting plate 2 may have reinforcing plates 21 protruding from both ends of the concrete tower 100 in the circumferential direction. In this case, the reinforcing plates 21 need to extend towards the side of the connecting plate 2 away from the extension plate 13 to avoid the extension plate 13.

[0047] In some embodiments, the connecting plate 2 is welded to the extension plate 13, and the extension plate 13 is welded to the reinforcing plate 12. This eliminates localized stress concentration caused by uneven bolt preload or angular deviation. Consequently, warping stress that may be caused by bolted connections is avoided, thereby further improving the structural integrity and torsional resistance of the concrete tower 100.

[0048] Of course, this application is not limited to this. In other embodiments, the connecting plate 2 and the extension plate 13 can be fixedly connected by means of screws, snap-fit, or other methods. The extension plate 13 and the reinforcing plate 12 can also be fixedly connected by means of screws, snap-fit, or other methods; or the extension plate 13 and the reinforcing plate 12 can be integrally formed.

[0049] Please see Figure 4 , Figure 4 for Figure 1 The diagram shows a partial structural schematic of the concrete tower 100. In some embodiments, in each first segment 1, there are multiple assembly slots 11, with multiple assembly slots 11 located at the same end of the first segment 1 arranged at intervals. It is understood that the number and position of the assembly slots 11 located at the same end of the first segment 1 can be determined according to the bearing capacity required during use and construction hoisting stages, and this application does not impose any limitations here. In addition, it is worth noting that at this time, there are also multiple reinforcing plates 12 in each first segment 1, with multiple reinforcing plates 12 corresponding one-to-one with multiple assembly slots 11.

[0050] This effectively alleviates stress concentration caused by a single connection point, allowing the connection load to be evenly distributed at the ends of the segments. Consequently, the overall structural stability and torsional resistance of the concrete tower 100 are improved.

[0051] Please see Figure 5 and combined Figure 6 ,in, Figure 5 for Figure 1 The diagram shows a cross-sectional view of the concrete tower 100 along line AA. Figure 6 for Figure 5 The diagram shows the assembly of the connecting plate 2, extension plate 13, reinforcing plate 12, and first segment 1 in the structure shown. Specifically, Figure 6 From Figure 5 This is a schematic diagram of the assembly of the connecting plate 2, the extension plate 13, the reinforcing plate 12, and the first segment 1 when viewed from below. In some embodiments, the connecting plate 2 is spaced apart from the wall of the assembly groove 11. This creates a gap around the connecting plate 2, providing more operating space for the operator. This, in turn, improves the assembly efficiency between the segments of the concrete tower 100.

[0052] Of course, this application is not limited to this. In other embodiments, the connecting plate 2 may be spaced apart from only a portion of the wall surface of the assembly groove 11. In still other embodiments, the connecting plate 2 may not be spaced apart from any of the wall surfaces of the assembly groove 11.

[0053] Please see Figure 5 and combined Figure 6In some embodiments, anchor bars 14 are embedded within the first segment 1, and the anchor bars 14 are fixedly connected to the reinforcing plate 12. Exemplarily, the anchor bars 14 and the reinforcing plate 12 can be fixedly connected by means of screws, snap-fitting, or welding. This makes the reinforcing plate 12 more securely embedded.

[0054] Please return to the reference. Figure 5 In some embodiments, multiple first reinforcing ribs 15 are embedded inside the adjacent ends of two adjacent first tube segments 1. This increases the structural strength of the adjacent ends of the two adjacent first tube segments 1, thereby effectively mitigating the cross-sectional weakening and stress concentration caused by the assembly groove 11. In this way, the structural stability of the concrete tower 100 can be improved.

[0055] It is worth noting that two adjacent first segments 1 in the circumferential direction of the concrete tower 100 form a ring, or when a certain first segment 1 is located between two other first segments 1 in the circumferential direction of the concrete tower 100, and the preset direction includes the circumferential direction of the concrete tower 100, multiple first reinforcing ribs 15 are embedded at both ends of the certain first segment 1 in the circumferential direction of the concrete tower 100.

[0056] Similarly, when a certain first segment 1 is located between two other first segments 1 in the axial direction of the concrete tower 100, and the preset direction includes the axial direction of the concrete tower 100, both ends of the certain first segment 1 in the axial direction of the concrete tower 100 are provided with multiple first reinforcing ribs 15.

[0057] Please see Figure 5 In some embodiments, first stirrups 16 are embedded inside the interior of the adjacent ends of two adjacent first segments 1; among the multiple first reinforcing ribs 15 and first stirrups 16 at one end of the same first segment 1, the first stirrups 16 are fixed to the outer periphery of the multiple first reinforcing ribs 15. Exemplarily, the way the first stirrups 16 are fixed to the outer periphery of the multiple first reinforcing ribs 15 includes, but is not limited to, closing and hooking the first reinforcing ribs 15 in the form of a 45-degree hook.

[0058] In this way, the lateral deformation of each first stiffener 15 can be effectively constrained, so that they can work together to bear the force, thereby making the stress more evenly distributed around the assembly groove 11, which can further reduce the cross-sectional weakening and stress concentration caused by the assembly groove 11.

[0059] Please see Figure 5In some embodiments, a plurality of second reinforcing ribs 17 are embedded within the first segment 1, and the plurality of second reinforcing ribs 17 are located on one side of the assembly groove 11 of the first segment 1 near the middle of the first segment 1. In this way, the structural strength of the adjacent ends of two adjacent first segments 1 can be further enhanced, thereby more effectively reducing the cross-sectional weakening and stress concentration caused by the assembly groove 11. In this way, the structural stability of the concrete tower 100 can be further improved.

[0060] It is worth noting that two adjacent first segments 1 in the circumferential direction of the concrete tower 100 form a ring, or when a certain first segment 1 is located between two other first segments 1 in the circumferential direction of the concrete tower 100, and the preset direction includes the circumferential direction of the concrete tower 100, a plurality of second reinforcing ribs 17 are embedded between the two ends of the certain first segment 1 in the circumferential direction of the concrete tower 100 and the middle part of the first segment 1.

[0061] Similarly, when a certain first segment 1 is located between two other first segments 1 in the axial direction of the concrete tower 100, and the preset direction includes the axial direction of the concrete tower 100, a plurality of second reinforcing ribs 17 are embedded between the two ends of the certain first segment 1 in the axial direction of the concrete tower 100 and the middle part of the first segment 1.

[0062] Please see Figure 5 In some embodiments, a second stirrup 18 is embedded in the first segment 1, and a plurality of second reinforcing ribs 17 are fixedly provided with second stirrups 18 on their outer periphery. In this way, the lateral deformation of each second reinforcing rib 17 can be effectively restrained, so that they can work together to bear the force, thereby making the stress more evenly distributed around the assembly groove 11, thereby further reducing the cross-sectional weakening and stress concentration caused by the assembly groove 11.

[0063] It is worth noting that, as mentioned above, when the first segment 1 is located between two other first segments 1, the plurality of second reinforcing ribs 17 have two clusters. In this case, the outer periphery of each cluster of second reinforcing ribs 17 may be fixed with second stirrups 18, or the outer periphery of only one cluster of second reinforcing ribs 17 may be fixed with second stirrups 18. This application does not impose any limitations here.

[0064] In some embodiments, the connecting plate 2, the extension plate 13, and the reinforcing plate 12 can all be, but are not limited to, steel components. This allows the high strength and toughness of steel to enhance the deformation capacity of the connecting plate 2, the extension plate 13, and the reinforcing plate 12, thereby increasing the load-bearing capacity of the concrete tower 100. This also reduces the amount of the first reinforcing rib 15, the first stirrup 16, the second reinforcing rib 17, and the second stirrup 18, thus helping to reduce costs.

[0065] In some embodiments, the first reinforcing rib 15, the first stirrup 16, the second reinforcing rib 17, the second stirrup 18, and the anchor bar 14 can all be, but are not limited to, steel components. In this way, the high strength and high toughness of steel can improve the deformation capacity of the first reinforcing rib 15, the first stirrup 16, the second reinforcing rib 17, the second stirrup 18, and the anchor bar 14, thereby further improving the load-bearing capacity of the concrete tower 100.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications or equivalent substitutions made within the spirit and principles of this application should be included within the protection scope of this application.
