Description

Technical Field

[0001] This invention relates to the field of bridge engineering construction, and in particular to a self-anchored suspension bridge anchorage structure for the load-bearing cable of the edge catwalk at the anchorage section. Background Technology

[0002] When the space for the anchorage support of the catwalk load-bearing cable of a self-anchored suspension bridge is small, some supports will not be able to be effectively fixed to the upper surface of the main beam of the anchorage section. If the supports are fixed in the traditional construction method, the size of the column is usually increased to reduce the number of columns, or the anchorage support is placed in a location with sufficient space. However, these two methods are prone to causing the spacing between the columns to be too small, which in turn leads to increased structural stress and insufficient construction space at the location of the cable loop. Utility Model Content

[0003] In view of this, the present invention aims to propose a self-anchored suspension bridge anchorage structure for the load-bearing cable of the edge catwalk at the anchorage section, in order to solve the problem of insufficient installation space on the main beam of the anchorage section during the installation of the load-bearing cable anchorage support.

[0004] To achieve the above objectives, the technical solution created by this utility model is implemented as follows:

[0005] An anchoring structure for the catwalk load-bearing cable at the edge of the anchoring section of a self-anchored suspension bridge includes: a vertical pole, a support beam, and an anchor beam for anchoring the catwalk load-bearing cable.

[0006] The support beam is disposed on the side wall of the anchoring section main beam and the upper surface of the support beam is provided with a fixing position for connecting the upright. The anchoring section main beam is provided with a first embedded part for connecting the upright. There are multiple uprights. At least one upright is connected to the support beam. The ends of the multiple uprights opposite to the anchoring section main beam or the support beam are connected to the anchor beam.

[0007] Furthermore, it also includes diagonal bracing, one end of which is fixed to the upper surface of the anchoring section main beam, and the other end is fixed to the side wall of the upright.

[0008] Furthermore, it also includes a connecting system, which is disposed on the plurality of the uprights.

[0009] Furthermore, the connection system includes two first connecting rods, which are arranged opposite each other along the length of the uprights and are used to connect multiple uprights.

[0010] Furthermore, the connection system also includes a second connecting rod, which is disposed between the two first connecting rods;

[0011] The plurality of the uprights are configured in two groups symmetrically arranged about the length of the main cable strands of the suspension bridge. Each group has the same number of uprights and at least two uprights. A second connecting rod connects two adjacent uprights in any group.

[0012] Furthermore, it also includes a load-bearing rod, one end of which is fixed to the lower surface of the support beam, and the other end is fixed to the side wall of the anchoring section main beam.

[0013] Furthermore, the support beam includes a load-bearing component and a support component. There are two load-bearing components, and the support component is fixedly connected between the two load-bearing components. The anchoring section of the main beam is provided with a second embedded part for connecting the load-bearing components, and the upper surface of the support component is provided with the fixing position.

[0014] Furthermore, there are multiple load-bearing rods, which are spaced apart along the length of the support member.

[0015] Furthermore, the anchoring section main beam is provided with a third embedded part for connecting the diagonal brace.

[0016] Through the above technical solution, when installing the anchoring structure for fixing the catwalk load-bearing cable on the main beam of the anchoring section, a support beam for installing the uprights is set on the side wall of the main beam of the anchoring section. This releases the space on the upper surface of the main beam of the anchoring section, ensuring the space required for the cable-stayed cable installation and preventing difficulties in installing the uprights due to insufficient space. At the same time, by using the support beam to install the uprights, the load of the catwalk load-bearing cable can be evenly distributed to each upright, avoiding the problem of stress concentration caused by reducing the number of uprights.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] In related technologies, the main beam of the anchorage section is equipped with an anchoring structure to connect the catwalk load-bearing cables. However, due to insufficient space on the upper surface of the main beam, some uprights cannot be properly arranged and effectively fixed. This can increase the difficulty of upright installation, reduce positioning accuracy, and consequently affect the construction of the load-bearing cables and the overall stability of the structure. Therefore, the insufficient space on the upper surface of the main beam can be alleviated by increasing the size of the uprights to reduce their number, or by changing the installation position of the uprights and rearranging them in areas with sufficient space on the main beam. However, reducing the number of uprights requires increasing their size, which increases the overall weight of the uprights and thus affects the anchorage. The reduced number of uprights places higher demands on the load-bearing capacity of the main beam section. Furthermore, the reduced number of uprights leads to a more concentrated stress distribution in the anchorage structure, making it prone to localized stress concentrations and impacting the long-term performance of the structure. Placing multiple uprights in spacious areas on the anchorage section of the main beam results in smaller intervals between them. Overly dense upright placement can lead to uneven spacing between anchor points of the load-bearing cables, affecting the stress on the cables and the overall structural balance. Additionally, overly dense upright placement on the anchorage section of the main beam occupies surrounding construction space, especially at locations with loose cable loops, potentially restricting construction operations, reducing efficiency, and even posing safety hazards.

[0028] Based on this, in a specific embodiment provided by this utility model, a self-anchored suspension bridge anchorage section edge catwalk load-bearing cable anchorage structure is provided, for reference. Figures 1 to 3 As shown, the self-anchored suspension bridge's edge catwalk support cable anchoring structure includes: a vertical pole 1, a support beam 2, and an anchor beam 3 for anchoring the catwalk support cable 9. The vertical pole 1 is the main load-bearing structure. The support beam 2 is located on the side wall of the main beam 4 of the anchoring section, and its upper surface has a fixing position for connecting the vertical pole 1. For example, the vertical pole 1 can be welded to the fixing position. The main beam 4 of the anchoring section has a first embedded part 401 for connecting the vertical pole 1. This first embedded part 401 strengthens the connection between the vertical pole 1 and the main beam 4 of the anchoring section. The connection strength between them is ensured, and the uprights 1 can be accurately installed at the designated positions on the anchoring section main beam 4. There are multiple uprights 1, and the installation positions of multiple uprights 1 are selected according to the actual situation. At least one upright is connected to the support beam 2 to avoid installation difficulties of uprights 1 due to insufficient space. An anchor beam 3 is connected to one end of multiple uprights 1 away from the anchoring section main beam 4 or support beam 2. The anchor beam 3 is supported by multiple uprights 1. The multiple uprights 1 are arranged at intervals to better bear the force from the catwalk load-bearing cable 9.

[0029] In some implementations, by arranging the support beam 2 on the side wall of the anchorage section main beam 4, the space on the upper surface of the anchorage section main beam 4 is greatly freed up, providing sufficient operating space for the cable-stayed construction. At the same time, the overall spatial layout of the anchorage section main beam 4 is optimized so that multiple uprights 1 can be more evenly distributed on the anchorage section main beam 4. That is, multiple uprights 1 evenly share the load of the catwalk load-bearing cable 9, avoiding the problem of stress concentration and excessive local stress caused by the reduction in the number of uprights.

[0030] Furthermore, by placing some of the uprights 1 on the support beam 2, the space occupied on the upper surface of the anchoring section main beam 4 can be reduced, ensuring the space required for the construction of the cable-stayed system. At the same time, by fixing the uprights 1 through the support beam 2 in conjunction with the anchoring section main beam 4, the position and spacing of the uprights 1 can be arranged more reasonably. While satisfying the structural stress of the uprights 1, it can also ensure the feasibility and convenience of construction operations.

[0031] In some implementations, reference Figures 1 to 3 As shown, a first embedded part 401 is pre-installed on the main beam 4 of the anchorage section, which can pre-plan the position of the upright 1 installed on the main beam 4 of the anchorage section. This not only enhances the connection strength between the upright 1 and the main beam 4 of the anchorage section, but also makes it easier for construction personnel to install the upright 1 accurately, conveniently and efficiently.

[0032] In some implementations, reference Figure 2 As shown, the anchoring section main beam 4 is also equipped with diagonal bracing rods 5 to support the upright 1. One end of the diagonal bracing rod 5 is fixed to the upper surface of the anchoring section main beam 4, and the other end is fixed to the side wall of the upright 1, so that the diagonal bracing rod 5, the upright 1 and the anchoring section main beam 4 form a triangular frame, thereby improving the rigidity and deformation resistance of the upright 1 and ensuring that the upright 1 does not tilt, bend or become unstable under high load.

[0033] For example, refer to Figure 2 As shown, the diagonal brace 5, by supporting the side wall of the upright 1, can effectively resist vibrations caused by external environment (such as strong winds, earthquakes, etc.), enhance the lateral deformation resistance of the upright 1 and the overall structure. At the same time, under dynamic load (such as catwalk construction or load fluctuation), the diagonal brace 5 can restrain the swaying and deformation of the upright 1, improve the overall dynamic performance and stability of the structure.

[0034] In some implementations, reference Figure 2As shown, the anchorage section main beam 4 is provided with a third embedded part 403 for connecting the diagonal brace 5. The third embedded part 403 can serve as a fixing point for the diagonal brace 5, ensuring a firm connection of the diagonal brace 5 on the main beam and preventing the diagonal brace 5 from loosening or displacing due to errors during construction or changes in force during operation. At the same time, through the third embedded part 403, the diagonal brace 5 can be fixed to the anchorage section main beam 4 at a precise angle and position, thereby forming an effective force transmission structure.

[0035] The third embedded part 403 reduces construction difficulty and improves construction accuracy. The third embedded part 403 is pre-embedded on the main beam 4 of the anchoring section. During the pre-embedding process, it is necessary to ensure the accuracy of its position and elevation to provide an installation foundation for the subsequent installation of the diagonal brace 5. That is, it is only necessary to connect the diagonal brace 5 to the third embedded part 403, avoiding the uncertainty of on-site drilling or welding.

[0036] In some implementations, reference Figure 1 As shown, multiple uprights 1 are connected by a connecting system 6. That is, by connecting multiple uprights 1, the connecting system 6 restricts the displacement and deformation of a single upright 1, so that multiple uprights 1 form a whole under stress, avoiding instability or displacement of a single upright 1 due to uneven stress. The load of the catwalk load-bearing cable 9 is transferred to the anchor section main beam 4 in sequence through the anchor beam 3, uprights 1 and connecting system 6. The setting of the connecting system 6 enables multiple uprights 1 to work together, better distributing local concentrated loads to multiple uprights 1, thereby reducing the stress burden on a single upright 1.

[0037] In some specific embodiments, reference is made to Figure 1 As shown, the connecting system 6 can constrain multiple uprights 1, effectively limiting the bending deformation of the uprights 1 under stress. Specifically, the connecting system 6 includes two first connecting rods 601, which are arranged opposite each other along the length of the uprights 1 and are used to connect multiple uprights 1. The relative arrangement of the two first connecting rods 601 significantly improves the overall stiffness of the multiple uprights 1, effectively constraining the deformation of the multiple uprights 1 under external force. Simultaneously, the connecting system 6 also includes a... The second connecting rod 602 is disposed between the two first connecting rods 601. That is, the second connecting rod 602 can further enhance the connection between the multiple uprights 1. The first connecting rod 601, the multiple uprights 1 and the second connecting rod 602 can form a more compact frame structure, further enhancing the integrity and rigidity of the multiple uprights 1. It can more evenly distribute the load from the outside, and disperse the local load through the first connecting rod 601 and the second connecting rod 602, avoiding overload on a single upright 1.

[0038] Furthermore, refer to Figure 1 As shown, multiple uprights 1 are configured in two groups symmetrically arranged about the length of the main cable strand 8 of the suspension bridge. The two groups of uprights 1 are arranged symmetrically about the length of the main cable strand 8 of the suspension bridge. The second connecting rod 602 can ensure that each group of uprights 1 maintains uniform stress under load and prevents structural instability caused by uneven stress.

[0039] Meanwhile, each group of uprights 1 has the same number of uprights 1 and at least two uprights 1. A second connecting rod 602 connects two adjacent uprights 1 in any group. That is, in each group, a second connecting rod 602 connects two adjacent uprights 1, which can enhance the connection strength of the uprights 1. Under the combined action of the first connecting rod 601 and the second connecting rod 602, the uprights 1 can cope well when subjected to loads in different directions.

[0040] For example, the two sets of uprights 1 are arranged symmetrically about the length of the main cable strand 8 of the suspension bridge. The ends of the two sets of uprights 1 away from the main beam 4 of the anchorage section are connected to the anchor beam 3. The catwalk load-bearing cable 9 is connected through the anchor beam 3 so that the catwalk formed by the catwalk load-bearing cable 9 is located in the middle position below the main cable strand 8 of the suspension bridge.

[0041] In some implementations, reference Figure 1 As shown, the load-bearing rod 7 is used to support the support beam 2. One end of the load-bearing rod 7 is fixed to the lower surface of the support beam 2, and the other end is fixed to the side wall of the anchoring section main beam 4. The load-bearing rod can be fixed to the lower surface of the support beam 2 by bolt connection or welding. A fourth embedded part for connecting the load-bearing rod can be pre-embedded on the anchoring section main beam 4. The load-bearing rod 7 is used to support the support beam 2, making the overall structure of the support beam 2 more stable, thereby providing good and stable support for the upright 1.

[0042] In some implementations, reference Figure 1 and Figure 3 As shown, the support beam 2 includes a load-bearing component 201 and a support component 202. There are two load-bearing components 201, and the support component 202 is fixed between the two load-bearing components 201. The anchoring section main beam 4 is provided with a second embedded part 402 for connecting the load-bearing components 201. The upper surface of the support component 202 is provided with a fixing position. The second embedded part 402 can ensure the accurate position of the load-bearing component 201 and avoid installation errors. Through the second embedded part 402, the load of the load-bearing component 201 can be transferred to the anchoring section main beam 4. At the same time, the fixing position provided on the upper surface of the support component 202 provides an installation foundation for the upright 1, making it convenient for construction personnel to install the upright 1 on the support component 202.

[0043] For example, the fixing position can be constructed as a welding substrate, which is fixed to the upper surface of the support member 202 for welding the upright 1 onto the welding substrate.

[0044] In some embodiments, there are multiple load-bearing rods 7, which are spaced apart along the length of the support member 202. The multiple load-bearing rods 7 can distribute the load transmitted by the support beam 2, making the force distribution more uniform and reducing the stress on a single load-bearing rod 7. For example, the multiple load-bearing rods 7 are arranged at equal intervals or regularly along the length of the support member 202, thereby ensuring the uniform transmission of the load along the length of the support beam 2.
