Description

Technical Field

[0001] This application relates to the technical field of suspension bridge construction, and in particular to a positioning bracket and construction method for a suspension bridge anchorage system. Background Technology

[0002] Currently, with the continuous development of transportation infrastructure such as highways and railways in my country, suspension bridges are being widely built across major rivers. A suspension bridge, also known as a suspension bridge, is a bridge that uses a suspension system consisting of main cables and suspenders as stiffening girders to transfer loads to the bridge towers and anchorages.

[0003] The main cable anchorage system is one of the most important components of a suspension bridge, bearing the enormous tensile force of the main cable and requiring high construction precision; the construction of the anchorage system is also a key process for controlling the construction period. The anchorage system is a structure directly connected to the cable strands, which typically exhibit a spatially divergent shape, therefore the anchorage system also possesses divergent spatial characteristics.

[0004] In related technologies, the anchoring units of an anchoring system are typically arranged in a rectangular pattern on a cross section perpendicular to its centerline. The projection of the main cable's centerline onto the bridge deck is parallel to the longitudinal axis of the main bridge. This means that adjacent rows of anchoring units in the same row are on the same horizontal line. During construction, only one distribution beam is needed for support in the same row, supplemented by a fine-tuning device. However, when the anchoring units are arranged in a staggered, quincunx pattern on a cross section perpendicular to its centerline, and the projection of the main cable's centerline onto the bridge deck has a certain angle with the longitudinal axis of the main bridge, adjacent rows of anchoring units in the same row are not on the same horizontal line. Conventional positioning supports cannot meet the installation and positioning requirements of the anchoring system, and cannot guarantee the installation accuracy. Therefore, it is necessary to design various fine-tuning devices of different specifications.

[0005] However, when the same row of two adjacent anchoring units in the anchoring system is not on the same horizontal line, the bracket design scheme in the relevant technology increases the input of steel, and various specifications of fine adjustment devices need to be carefully processed and installed according to the design, which is quite cumbersome. Summary of the Invention

[0006] This application provides a positioning bracket and construction method for a suspension bridge anchorage system to solve the problem that when two adjacent columns of anchorage units in the same row are not on the same horizontal line, the bracket design in related technologies increases the input of steel materials, and various specifications of fine adjustment devices need to be carefully processed and installed according to the design, which is quite cumbersome.

[0007] On the one hand, this application provides a positioning bracket for a suspension bridge anchorage system, and the technical solution adopted is:

[0008] A positioning bracket for a suspension bridge anchorage system, comprising:

[0009] A multi-layer support assembly is provided at intervals along the extension direction of the anchoring unit of the anchoring system. Each layer of the support assembly includes multiple V-shaped support beams spaced vertically apart. The multiple V-shaped support beams are located in a plane perpendicular to the center line of the anchoring system. Multiple front positioning devices for the anchoring unit to pass through are provided at intervals on the V-shaped support beams for adjusting the position of the anchoring unit and keeping it in a set position.

[0010] Front bracket for supporting the support assembly;

[0011] The rear support assembly is used to secure the ends of each anchoring unit in the anchoring system.

[0012] In some embodiments, the V-shaped support beam comprises two beam segments distributed in a V-shape, the two beam segments being symmetrically arranged with respect to the vertical plane containing the centerline of the anchoring system.

[0013] In some embodiments, the front positioning device includes:

[0014] Two limiting members are provided on the V-shaped support beam and located above the V-shaped support beam, and are spaced apart along the length of the V-shaped support beam. The two limiting members and the V-shaped support beam form a positioning space for the anchoring unit to pass through.

[0015] A positioning tube, which is located within the positioning space, is used for the anchoring unit to pass through;

[0016] An adjustment component is used to adjust and maintain the position of the positioning tube in a plane perpendicular to the centerline of the anchoring system.

[0017] In some embodiments, the rear support assembly includes:

[0018] The rear anchor beam system is used to connect the ends of the anchoring units of the anchoring system.

[0019] Multiple rear positioning devices are provided on the rear anchor beam system to adjust the position of the end of the anchoring unit and fix the end of the anchoring unit in a set position;

[0020] The rear support bracket is used to support the rear anchor beam system.

[0021] In some embodiments, the rear anchor beam system includes:

[0022] Multiple longitudinal beams are arranged parallel to and perpendicular to the vertical plane containing the center line of the anchoring system. The multiple longitudinal beams are located in a plane perpendicular to the center line of the anchoring system and are spaced apart along a direction perpendicular to their axis.

[0023] Multiple crossbeams, perpendicular to the longitudinal beams and connected to the rear support, are used to support the longitudinal beams.

[0024] In some embodiments, the longitudinal beam is used to connect to the end of the anchoring unit, and the rear positioning device is disposed on the longitudinal beam.

[0025] In some embodiments, each of the longitudinal beams is provided with a plurality of the rear positioning devices, and the plurality of the rear positioning devices are spaced apart along the axial direction of the longitudinal beam.

[0026] In some embodiments, the front support includes a plurality of support units, which are spaced apart in the extension direction of the anchoring unit of the anchoring system, and each support unit is provided with at least one set of support components.

[0027] On the other hand, this application provides a construction method for a suspension bridge anchorage system, comprising:

[0028] Post-construction support components, front support, and support components;

[0029] Install the anchoring system and complete its rough positioning;

[0030] Adjust the anchoring unit of the anchoring system to the set position using the front positioning device, and keep it in that set position;

[0031] Pour the anchor concrete.

[0032] In some embodiments, the anchoring system is divided into multiple layers from bottom to top, and each layer of the anchoring system, along with the corresponding positioning brackets and anchor concrete, is constructed sequentially from bottom to top.

[0033] The beneficial effects of the technical solution provided in this application include:

[0034] This application provides a positioning bracket for a suspension bridge anchorage system. It utilizes V-shaped support beams, with multiple layers of V-shaped support beams supporting multiple rows of anchorage units. The V-shaped support beams are designed to match the distribution of the same row of anchorage units on a cross-section perpendicular to the anchorage system's centerline, ensuring that the distance from the same row of anchorage units to the V-shaped support beams is the same. Multiple front positioning devices are then used to position and connect to the multiple anchorage units. These front positioning devices adjust the position of the anchorage units and hold them in a set position, achieving precise positioning of the anchorage units and meeting the installation and precise positioning requirements of the anchorage system. Since the distance from the same row of anchorage units to the V-shaped support beams is the same, the specifications of the front positioning devices corresponding to a single V-shaped support beam can be designed to be consistent. This uniformity in specifications reduces steel input and allows for mass production, saving component processing and installation time. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, 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.

[0043] This application provides a positioning bracket and construction method for a suspension bridge anchorage system, which can solve the problem that current bracket designs increase steel input and require careful processing and installation of various specifications of fine-tuning devices when the same row of two adjacent anchorage units in the anchorage system is not on the same horizontal line, which is quite cumbersome.

[0044] Reference Figure 1-5 As shown in the embodiment of this application, a positioning bracket for a suspension bridge anchorage system includes a multi-layer support assembly 1, a front bracket 2, and a rear bracket assembly 3. The multi-layer support assembly 1 is used to be spaced out along the extension direction of the anchorage unit of the anchorage system. Each layer of support assembly 1 includes multiple V-shaped support beams 11 spaced out vertically. The multiple V-shaped support beams 11 are located in a plane perpendicular to the center line of the anchorage system. Multiple front positioning devices 12 are spaced out on the V-shaped support beams 11 for the anchorage unit to pass through, which are used to adjust the position of the anchorage unit and keep it in a set position. The front bracket 2 is used to support the support assembly 1, and the rear bracket assembly 3 is used to fix the ends of each anchorage unit of the anchorage system.

[0045] Reference Figure 1-2 As shown, specifically in this embodiment, among the multiple columns of anchoring units in the anchoring system, the central column is located in the vertical plane where the center line of the anchoring system is located, and the number of rows in each column of anchoring units gradually decreases along the direction away from the vertical plane where the center line of the anchoring system is located.

[0046] Reference Figure 1-2 As shown, the V-shaped support beam further includes two beam segments 111 arranged in a V-shape, with the two beam segments 111 symmetrically arranged with the vertical plane containing the center line of the anchoring system as the symmetrical plane. Among the multiple columns of anchoring units on both sides of the vertical plane containing the center line of the anchoring system, the anchoring units in the same row are connected to the two beam segments 111 of the corresponding V-shaped support beam. In the column of anchoring units within the vertical plane containing the center line of the anchoring system, each anchoring unit is connected to the connection point of the two beam segments 111 in the corresponding V-shaped support beam. Correspondingly, a front positioning device 12 is provided on the beam segment 111 at the installation position corresponding to the anchoring unit, and a front positioning device 12 is provided at the connection point of the two beam segments 111. In this embodiment, the two beam segments 111 are directly connected by the front positioning device 12. Since the topmost anchoring unit in the column of anchoring units within the vertical plane containing the center line of the anchoring system is in a separate row, there is no need to set up a V-shaped support beam. Instead, a horizontal support beam is used to support it, and a front positioning device 12 is set on the horizontal support beam.

[0047] Reference Figure 2-3 As shown, the front positioning device 12 further includes two limiting members 121, a positioning tube 122, and an adjustment assembly. The two limiting members 121 are disposed on the V-shaped support beam 11 and located above the V-shaped support beam, and are spaced apart along the length of the V-shaped support beam 11. The two limiting members 121 and the V-shaped support beam 11 form a positioning space for the anchoring unit to pass through. The positioning tube 122 is disposed in the positioning space for the anchoring unit to pass through. The adjustment assembly is used to adjust the position of the positioning tube 122 in a plane perpendicular to the center line of the anchoring system and keep it in that position.

[0048] Reference Figure 2-3 As shown, specifically, the limiting member 121 can be a limiting rod or a limiting plate, etc., which is fixed on the V-shaped support beam. The positioning tube 122 can be pre-installed on the anchoring unit to set the position. The adjustment assembly includes three adjusting bolts 123, which are respectively bolted and assembled on the V-shaped support beam and the two limiting members 121, and are located in the positioning space. The axes of the adjusting bolts 123 are all located in a plane perpendicular to the center line of the anchoring system. The positioning tube 122 is located between the three adjusting bolts 123 and contacts the head of the adjusting bolts 123, so that the position of the positioning tube 122 can be adjusted by turning the adjusting bolts 123, thereby realizing the function of adjusting the position of the positioning tube 122 and keeping the positioning tube 122 in the set position. After the adjustment is completed, the adjusting bolts 123 are welded and fixed to the positioning tube 122. In this embodiment, the two limiting members 121 are also connected by an anti-disengagement rod 124 to restrict the positioning tube 122 from moving out of the positioning space.

[0049] Reference Figure 2 As shown, in this embodiment, since the two beam segments 111 of the V-shaped support beam are connected by the front positioning device 12, the two limiting members 121 in the front positioning device 12 between the two beam segments 111 are fixedly connected at the bottom by a support member. Correspondingly, three adjusting bolts 123 are installed on the support member and the two limiting members 121. Specifically, the limiting members 121 and the support member can be made of angle steel or channel steel and welded to the V-shaped support beam or welded to each other.

[0050] Reference Figure 1-4 As shown, the front support 2 is designed based on the structure of multiple sets of support components 1. Specifically, the front support 2 includes multiple support units, which are distributed at intervals in the extension direction of the anchoring unit of the anchoring system. Each support unit is provided with at least one set of support components 1. The number of support units is set according to the calculation results during the design, and can be three or two. In this embodiment, there are five sets of support components 1 and two support units. The support unit near the main cable is provided with two sets of support components 1, and the support unit near the rear support 31 is provided with three sets of support components 1. According to the change of the cross-sectional area of ​​the anchoring system along its centerline direction, the support components 1 cooperate with the anchoring system. The size of the support components 1 gradually increases in the direction away from the main cable. Correspondingly, the size of the support unit gradually increases in the direction away from the main cable.

[0051] Reference Figure 1As shown, in this embodiment, the support unit includes a front upper support 21 and a front lower support 22. The support component 1 is installed on the front upper support 21, and the front upper support 21 is connected to the front lower support 22. The front lower support 22 is fixed to the anchor body to support the front upper support 21. During construction, the anchor body pre-embeds the front lower support 22 and installs the pre-embedded part 4. When constructing the front lower support 22, it is fixed to the pre-embedded part 4. The positioning of the pre-embedded part 4 needs to be strictly controlled and accurately positioned. The front upper support 21 adopts a standard frame structure, which can be divided into multiple layers of frames along the direction perpendicular to the center line of the anchoring system and from bottom to top. The multiple layers of frames are connected and fixed in sequence to form the front upper support 21.

[0052] Reference Figure 1 and Figure 5 As shown, the rear support assembly 3 further includes a rear anchor beam system 32, multiple rear positioning devices 33 and a rear support 31. The rear anchor beam system 32 is used to connect the ends of the anchoring units of the anchoring system. The multiple rear positioning devices 33 are provided on the rear anchor beam system 32 and are used to adjust the position of the ends of the anchoring units. The rear support 31 is used to support the rear anchor beam system 32.

[0053] Reference Figure 1 and Figure 5 As shown, the rear anchor beam system 32 includes multiple longitudinal beams 321 and multiple transverse beams 322. The multiple longitudinal beams 321 are parallel to and perpendicular to the vertical plane containing the center line of the anchoring system. The multiple longitudinal beams 321 are located in a plane perpendicular to the center line of the anchoring system. The multiple longitudinal beams 321 are spaced apart in a direction perpendicular to their axis. The multiple transverse beams 322 are perpendicular to the longitudinal beams 321 and connected to the rear support 31 to support the longitudinal beams 321.

[0054] Reference Figure 1 and Figure 5 As shown, specifically, the longitudinal beam 321 is used to connect with the anchoring unit, and the rear positioning device 33 is installed on the longitudinal beam 321. The position of the longitudinal beam 321 is designed according to the position of multiple rows of anchoring units in the anchoring system. Each row of anchoring units corresponds to one longitudinal beam 321 or multiple longitudinal beams 321 arranged coaxially. Then, multiple rear positioning devices 33 are provided on each longitudinal beam 321, and the multiple rear positioning devices are spaced apart along the axial direction of the longitudinal beam 321.

[0055] In this embodiment, both the crossbeam 322 and the longitudinal beam 321 are made of channel steel. The rear positioning device 33 on the longitudinal beam 321 is installed on the inner side of the channel steel, specifically including a positioning bracket and three positioning bolts. The positioning bracket is made of angle steel or channel steel and is fixed to the inner side of the channel steel of the longitudinal beam 321 to support the anchoring unit. The three positioning bolts are respectively bolted and assembled on the two side walls of the supporting bracket and the channel steel of the longitudinal beam 321, facing the inner side of the channel steel. During installation, the pre-embedded pipe at the end of the anchoring unit is placed between the three positioning bolts. The position of the end of the anchoring unit is adjusted by adjusting the three positioning bolts to complete the positioning of the end of the anchoring unit. After positioning, the positioning bolts are welded and fixed to the pre-embedded pipe at the end of the anchoring unit to complete the connection between the anchoring unit and the longitudinal beam 321.

[0056] Reference Figure 1 and Figure 5 As shown, the rear support 31 is used to be installed on the anchor body and support the rear anchor beam system 32. The structure of the rear support 31 is designed according to the support requirements of the rear anchor beam system 32. During construction, it is fixed with the embedded part 4 embedded in the anchor body. The position of the embedded part 4 needs to be accurately positioned and installed. Furthermore, the rear support 31 can be designed as two parts distributed vertically. During construction, it can be installed in two stages from bottom to top, or it can be designed as a whole and completed in one go according to the terrain conditions.

[0057] All parts of the positioning bracket can be made of common bracket materials, such as steel bars, steel plates, angle steel, channel steel, I-beams, H-beams, etc.

[0058] In the above-mentioned anchoring system, the anchoring unit can be in the form of prestressed steel strand, steel section, anchor rod, etc. The extension direction of the anchoring unit is its axial direction, and the center line of the anchoring system is the axial direction of the anchoring unit located at the center.

[0059] This embodiment also provides a construction method for a suspension bridge anchorage system, which uses the aforementioned suspension bridge anchorage system positioning bracket and includes the following steps:

[0060] After construction, the support assembly 3, the front support 2, and the support assembly 1 are constructed.

[0061] Install the anchoring system and complete its rough positioning.

[0062] The anchoring unit of the anchoring system is adjusted to the set position by the front positioning device 12 and kept in the set position.

[0063] Pour the anchor concrete.

[0064] Specifically, the construction of the anchoring system and the anchor concrete are carried out simultaneously and in layers. The anchoring system is first divided into multiple layers from bottom to top, and each layer of the anchoring system, as well as the corresponding positioning brackets and anchor concrete, are constructed sequentially from bottom to top.

[0065] Specifically, during the construction of each anchoring system, the following steps are taken: first, the construction of the rear support 31 and its embedded parts 4, the rear anchor beam system 32, the front lower support 22 and its embedded parts 4, and the installation of the front upper support 21 and its positioning distribution beam are carried out; after the positioning support is completed, the corresponding anchoring system is installed and roughly positioned, and then the precise positioning and fixing of the anchoring system is completed through the front positioning device 12 and the rear positioning device 33. After completion, the anchor body concrete of this part is poured.

[0066] The anchoring system positioning supports all use common support materials, such as steel bars, steel plates, angle steel, channel steel, I-beams, and H-beams. The installation of the anchoring system positioning supports is carried out simultaneously with the construction of the anchor body concrete, which can significantly reduce the amount of support material used.

[0067] The embodiments of this application have the following advantages:

[0068] 1. The anchoring system bracket only needs to bear the weight of the structure and the anchoring system. The support component 1 on the front upper bracket 21 adopts a symmetrically arranged V-shaped support beam 11, which has a simple structure and clear stress.

[0069] 2. The positioning brackets can all be made of common bracket materials. The materials are highly replaceable, widely available, low in cost, and easy to manufacture.

[0070] 3. The support component 1 on the upper support adopts a symmetrically arranged V-shaped support beam 11, which is suitable for situations where the distribution of anchoring units on the cross section perpendicular to the center line of the anchoring system presents a staggered quincunx arrangement, and the projection of the center line of the main cable on the bridge deck has a certain angle with the longitudinal axis of the main bridge, and the same row of two adjacent columns of anchoring units in the anchoring system is not on the same horizontal line.

[0071] 4. The installation of the anchoring system positioning bracket is carried out simultaneously with the construction of the anchor body concrete, which can significantly reduce the amount of material used for the bracket. Correspondingly, the number of personnel and installation time are reduced, and the construction cost is low.

[0072] 5. This construction method is applicable to the installation of suspension bridge anchorage systems and has a wide range of applications.
