Description

Technical Field

[0001] This application relates to the field of concrete main tower construction technology, and in particular to a cable guide positioning device and construction method suitable for cross anchorage zones. Background Technology

[0002] Cable-stayed bridges are highly statically indeterminate structures with complex stress distribution, significant inter-component influence, and controllable internal forces and linearity. The cable guide tube, a crucial component of the cable anchorage zone, requires precise positioning and installation to prevent damage from friction between the cable and the tube wall, which could affect the bridge's quality. The welding process and subsequent concrete pouring of the bridge beams can easily cause positional deviations in the already positioned cable guide tubes. These deviations can lead to friction between the cable and the cable guide tube during subsequent cable tensioning, affecting the overall stress distribution of the cable. Furthermore, the spatial angle between the cable and the tower, and the varying positions of each layer of cable relative to the tower, along with the increased spatial complexity of cross-anchored cables, places higher demands on component material preparation, processing, and cable guide tube positioning.

[0003] The conventional method for positioning cable guide pipes involves first fabricating a positioning frame, welding it to the tower column, then hoisting the cable guide pipe, measuring and positioning it, and finally welding the cable guide pipe to the positioning frame. Because cable guide pipe installation is a three-dimensional spatial positioning operation, repeated measurements, fixing, and disconnection are required during installation, resulting in low construction accuracy and inefficiency.

[0022] 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.

[0023] This application provides a cable guide positioning device and construction method suitable for cross-anchorage areas, which can solve the problems in related technologies where cable guide positioning construction in cross-anchorage areas requires repeated measurement and fixing or unconnecting, resulting in low construction accuracy and low efficiency.

[0024] Conventional cable guide duct positioning construction requires first fabricating a positioning frame, welding it to the tower column, then hoisting the cable guide duct, measuring and positioning it, and finally welding the cable guide duct to the positioning frame. Since cable guide duct installation is a three-dimensional spatial positioning operation, repeated measurements, fixing, and disconnection are necessary during installation, resulting in low construction accuracy and inefficiency. Therefore, a positioning installation frame that can be hoisted to the installation area after initial positioning, along with a component for fine-tuning the cable guide duct that can be detachably connected to it, is designed. This allows for convenient initial positioning of the cable guide duct on the ground, followed by hoisting it as a whole to the tower column construction segment, reducing high-altitude work, facilitating parallel operations, improving efficiency, and shortening the construction period. Then, in the installation area, the fine-tuning component is used to precisely position each part of the cable guide duct to meet construction and installation standards. After fine-tuning the cable guide duct, the fine-tuning component can be removed and reused in the next segment, saving materials and effectively reducing construction costs. This solves the problem of low construction accuracy and inefficiency in cable guide duct positioning construction in cross-anchoring areas, which requires repeated measurements and fixing or disconnection.

[0025] refer to Figure 1-2 A cable guide positioning device suitable for cross-anchoring areas includes: a positioning frame 1, which includes two spaced vertical frames 2 and a crossbeam frame 3 connecting the two vertical frames 2; an upper longitudinal positioning component 4, which is disposed on the crossbeam frame 3, and a cable guide 5 that is inclinedly passing through the two vertical frames 2 is adjustablely suspended in the upper longitudinal positioning component 4; a lower longitudinal positioning component 6, which is disposed on the corresponding vertical frame 2 and is adjustablely connected to the cable guide 5; and a transverse positioning component 7, which is disposed on the corresponding vertical frame 2 and is adjustablely connected to the cable guide 5.

[0026] Through this structural design, the positioning device for the cable guide 5 aims to improve installation accuracy and convenience. The positioning frame 1 consists of two spaced vertical frames 2 and a crossbeam frame 3 connecting these two vertical frames 2, forming a stable support structure. The upper longitudinal positioning component 4 is installed on the crossbeam frame 3 and suspended from the cable guide 5. This upper longitudinal positioning component 4 has an adjustable suspension length, allowing adjustment of the longitudinal elevation and tilt angle of the cable guide 5 to ensure it can be adjusted according to construction needs. The lower longitudinal positioning component 6 is installed on the corresponding vertical frame 2, and it can also adjust the longitudinal elevation and tilt angle of the cable guide 5. Together with the upper longitudinal positioning component 4, it allows for complete and precise adjustment of the elevation and tilt angle of the entire cable guide 5. The lateral positioning component 7 is also located on the corresponding vertical frame 2, and it is adjustablely connected to the cable guide 5, allowing for lateral positioning adjustment of the cable guide 5 and flexible adjustment of its lateral position. Each component is equipped with an adjustable connection structure. The positioning device allows for positional adjustment of the cable guide 5 at different locations, facilitating fine-tuning during construction to meet the needs of various installation environments and significantly improving construction efficiency and accuracy. The adjustability and stability of this positioning device meet the requirements of complex construction environments, ensuring project safety. It effectively solves the problems of repeated measurements and inconvenient adjustments inherent in traditional methods.

[0027] In some preferred embodiments, the vertical frame 2 includes a rectangular frame, with a first crossbeam 23 laterally provided in the middle of the rectangular frame, dividing the rectangular frame into a first opening 21 at the top and a second opening 22 at the bottom; the cable guide 5 passes through the second opening 22 of one of the vertical frames 2 and exits through the first opening 21 of the other vertical frame 2, and is adjustablely connected to the upper longitudinal positioning component 4, the lower longitudinal positioning component 6 and the transverse positioning component 7 respectively, forming a single cable guide positioning structure.

[0028] In this embodiment, the vertical frame 2 is rectangular with a first crossbeam 23 in the middle, dividing the frame into upper and lower sections. This design provides support for the cable guide 5 and facilitates vertical adjustment. A first opening 21 is located at the top of the rectangular frame, allowing the cable guide 5 to pass through; a second opening 22 is located at the bottom of the rectangular frame, through which the cable guide 5 passes. This design ensures that the cable guide 5 can be positioned as required within the positioning frame. The cable guide is adjustablely connected to the upper longitudinal positioning component 4, the lower longitudinal positioning component 6, and the transverse positioning component 7. This design allows for adjustment of the cable guide's elevation, tilt angle, and lateral deviation during actual construction, ensuring both flexibility and precision. This design creates a single-unit cable guide 5 positioning structure, enabling the entire device to achieve rapid positioning while maintaining excellent stability.

[0029] In some preferred embodiments, the vertical frame 2 includes two adjacent rectangular frames; two cable guides 5 passing through one of the vertical frames 2 are respectively inserted into the corresponding first opening 21 and second opening 22 of the two rectangular frames, and exit through the corresponding first opening 21 and second opening 22 of the two rectangular frames of the other vertical frame 2, forming a cross-type cable guide positioning structure; both cable guides 5 are adjustablely connected to the upper longitudinal positioning component 4, the lower longitudinal positioning component 6 and the transverse positioning component 7 respectively.

[0030] With this structural design, the vertical frame 2 comprises two adjacent rectangular frames. Each rectangular frame has two openings, one at the top and one at the bottom, to facilitate the insertion and exit of the two cable guides 5. This design provides greater flexibility to form a cross-shaped cable guide 5 positioning structure. In the cross-shaped cable guide 5 positioning structure, both cable guides 5 are adjustablely connected to the upper longitudinal positioning component 4, the lower longitudinal positioning component 6, and the transverse positioning component 7, and both cable guides 5 are independently adjustable, providing a flexible adjustment and positioning scheme.

[0031] In some preferred embodiments, the crossbeam frame 3 is provided with a second crossbeam 31 parallel to the first crossbeam 23; the upper longitudinal positioning component 4 includes a wire rope 8, a first adjusting member, a hanging frame component 9 and a locking component 10; one end of the first adjusting member is hooked to the second crossbeam 31 by the wire rope 8, and the other end is adjustablely connected to the hanging frame component 9, and a cable guide 5 is hingedly suspended inside the hanging frame component 9; the locking component 10 connects the hanging frame component 9 and the cable guide 5 to lock the cable guide 5 longitudinally.

[0032] In this embodiment, the second crossbeam 31 is designed to cooperate with the upper longitudinal positioning component 4 to suspend and adjust the cable guide 5. The upper longitudinal positioning component 4 includes several key components. One end of the steel wire rope is connected to the second crossbeam 31, and the other end is connected to the first adjusting component, which is connected to the lifting frame component 9. The cable guide 5 is stably hinged to the lifting frame component 9. To make fine adjustments to the tilt angle while adjusting the elevation, the length of the first adjusting component is changed to control this parameter, thereby precisely adjusting the longitudinal elevation of the cable guide 5. This structural design enhances the positioning function of the cable guide 5 and significantly improves the stability of the entire structure. The locking component 10 connects the lifting frame component 9 and the cable guide 5, fixing the cable guide 5 longitudinally through a locking mechanism. Once adjusted to the appropriate position, the locking component 10 ensures that the cable guide will not move due to external forces, ensuring the safety and stability of construction.

[0033] In some preferred embodiments, the suspension frame assembly 9 includes an adjusting beam 91 and a rotating saddle 92; the two ends of the adjusting beam 91 are provided with first vertical rods 93, and the ends of the two first vertical rods 93 away from the adjusting beam 91 are provided with first lifting lugs 94. The cable guide 5 is suspended on the rotating saddle 92 by setting pins 95 on the first lifting lugs 94 and hinged to them respectively; the first adjusting member is adjustablely connected to the adjusting beam 91.

[0034] Through this structural design, the adjusting beam 91 is used for adjustable connection with the first adjusting member, that is, changing the length of the first adjusting member to achieve longitudinal positioning adjustment of the cable guide 5; the rotating saddle 92 is located at the bottom of the lifting frame assembly 9, and the design of the first vertical rod 93 and the first lifting lug 94 is to allow the rotating saddle 92 to fit and overlap with the cable guide 5 and to rotate in multiple directions, thereby allowing the cable guide 5 to be adjusted at necessary angles during installation to adapt to different working environments. The lifting frame assembly 9 of this embodiment not only has good operational flexibility, but also improves the safety of operating the cable guide 5, providing stable support for construction projects.

[0035] In some preferred embodiments, the locking assembly 10 includes a wire rope 8, a second adjusting member, and a second lifting lug 101. The second lifting lug 101 is disposed on the cable guide 5 and is located on the same side of the cable guide 5 as the rotating saddle 92. A third lifting lug 921 is provided at the bottom of the rotating saddle 92. One end of the second adjusting member is fixedly connected to the second lifting lug 101, and the other end of the second adjusting member is connected to the third lifting lug 921 by the wire rope 8 to lock the cable guide 5 longitudinally.

[0036] With this structural design, the second lifting lug 101 is mounted on the cable guide 5 and is located on the same side of the cable guide 5 as the rotating saddle 92. A third lifting lug 921 is provided at the bottom of the rotating saddle 92, thus providing a connector for the connection with the second lifting lug 101. The main function of the second adjusting member is adjustment and locking; one end is fixedly connected to the second lifting lug 101, and the other end is connected to the third lifting lug 921 via a steel wire rope 8, forming a stable locking structure. It should be noted that the second adjusting member can also change its length, thereby achieving tautness to lock or loosen the cable guide 5 longitudinally, thus adjusting and positioning the cable guide 5.

[0037] In some preferred embodiments, the lower longitudinal positioning component 6 includes a wire rope 8, a first adjusting member and a second lifting lug 101; one end of the first adjusting member is connected to the first crossbeam 23 via the wire rope 8, the second lifting lug 101 is provided at the cable guide 5 where the first adjusting member is projected vertically downward, and the other end of the first adjusting member is tunably connected to the second lifting lug 101.

[0038] Through this structural design, the wire rope 8 is used to connect the first adjusting member and the first crossbeam 23, providing stable longitudinal support. The first adjusting member is designed to achieve an adjustable connection between the wire rope 8 and the second lifting lug 101. Similarly, by changing the length of the first adjusting member, the longitudinal elevation of the lower part of the cable guide 5 is adjusted and positioned. In conjunction with the upper longitudinal positioning component 4, complete longitudinal elevation adjustment and positioning of the cable guide 5 is achieved. This forms a compact and high-performance positioning system.

[0039] In some preferred embodiments, both the first adjusting member and the second adjusting member are turnbuckles 11.

[0040] This section specifies the first and second adjusting components, using turnbuckles as the adjusting components. Turnbuckles are a type of bolt with a special shape, offering excellent force distribution and connection stability. Adjusters can fine-tune the longitudinal elevation of the cable guide 5 by rotating the turnbuckle 11, greatly facilitating on-site adjustment and installation.

[0041] In some preferred embodiments, the lateral positioning component 7 includes a third crossbeam 71, which is parallel to the second crossbeam 31 and mounted on a rectangular frame, and is located below the wall of the cable guide 5 currently in the first opening 21 or the second opening 22; a second vertical rod 72 perpendicular to the third crossbeam 71 is provided on both sides of the cable guide 5 on the third crossbeam 71, and an opening is provided at the end of the second vertical rod 72 away from the third crossbeam 71, and a lateral pushing bolt 73 is provided in the opening to extend and retract along the opening direction to resist and push the cable guide 5; a fixed saddle 74 is provided at the top of the third crossbeam 71, and a welding gap is provided between it and the corresponding cable guide 5.

[0042] Through this structural design, the lateral positioning component 7 introduces a third crossbeam 71, which is set parallel to the second crossbeam 31 on the rectangular frame, mainly for supporting and stabilizing the cable guide 5. On both sides of the third crossbeam 71, and at both ends of the cable guide 5, are second vertical rods 72 distributed perpendicularly to the third crossbeam 71, with openings near the cable guide 5. Each opening of the second vertical rod 72 contains a lateral pushing bolt 73. This design allows the lateral pushing bolts 73 to extend and retract along the direction of the openings to resist and push the cable guide 5, achieving the purpose of lateral adjustment of deviation. It should be noted that, through the design of the fixed saddle 74 and the pre-reserved welding gap between it and the cable guide 5, after precise adjustment, the cable guide 5 is welded to the fixed saddle 74, thereby fixing the cable guide 5 to the positioning frame 1.

[0043] This application provides a method for positioning cable guides in cross-anchorage zones, referring to... Figure 3 , Figure 3 A flowchart illustrating the cable guide positioning construction method applicable to cross-anchorage zones, such as... Figure 3 As shown, the cable guide positioning construction methods applicable to cross-anchorage zones include:

[0044] Step 101: The cross-shaped cable guide 5 positioning structure, which is initially positioned and temporarily locked on the ground, is lifted as a whole to the tower construction segment for installation. Through this step, the cable guide 5 is initially positioned on the ground using the positioning frame 1 and positioning components, and then lifted as a whole to the tower construction segment, which can reduce high-altitude operations, improve work efficiency, and shorten the construction period.

[0045] Step 102: Use the upper longitudinal positioning component 4, the lower longitudinal positioning component 6, and the transverse positioning component 7 to precisely adjust and position the corresponding cable guide 5. Through this step, in the construction and installation area, according to the construction and installation standards, use the upper longitudinal positioning component 4, the lower longitudinal positioning component 6, and the transverse positioning component 7 to precisely adjust the longitudinal elevation, tilt angle, and transverse deviation of the cable guide 5.

[0046] Step 103: Weld and fix the cable guide 5 to the positioning frame 1, remove the unnecessary upper longitudinal positioning component 4, lower longitudinal positioning component 6, and transverse positioning component 7, and reuse them in the next construction segment of the cable guide 5. Through this step, each fine-tuning component can be removed after the cable guide is finely positioned and reused in the next segment, saving materials and effectively reducing construction costs.

[0047] This construction method involves initially positioning and temporarily locking the cable guide 5 before lifting. Using hoisting equipment, the entire cross-shaped cable guide 5 positioning structure, along with the cable guide 5 itself, is lifted to the target tower construction segment. All connection points must be secure during hoisting. After lifting, the upper longitudinal positioning component 4, lower longitudinal positioning component 6, and transverse positioning component 7 are used to precisely adjust and position the cable guide 5. Once the cable guide 5 is correctly positioned, welding is performed to fix it to the positioning frame 1. After welding, the unused upper longitudinal positioning component 4, lower longitudinal positioning component 6, and transverse positioning component 7 are removed sequentially and reused in the next cable guide 5 construction positioning. It is important to note that the fine-tuning components should be cleaned and maintained for reuse in subsequent cable guide 5 construction segments, ensuring efficient use of construction resources.

[0048] The beneficial effects of this invention include:

The positioning frame 1 consists of two spaced vertical frames 2 and a crossbeam frame 3 connecting these two vertical frames 2, forming a stable support structure. The upper longitudinal positioning component 4 is installed on the crossbeam frame 3 and suspended from the cable guide 5. This upper longitudinal positioning component 4 has an adjustable suspension length, allowing adjustment of the longitudinal elevation and tilt angle of the cable guide 5 to ensure it can be adjusted according to construction needs. The lower longitudinal positioning component 6 is installed on the corresponding vertical frame 2, and it can also adjust the longitudinal elevation and tilt angle of the cable guide 5. Together with the upper longitudinal positioning component 4, it allows for complete and precise adjustment of the elevation and tilt angle of the entire cable guide 5. The lateral positioning component 7 is also located on the corresponding vertical frame 2 and is adjustablely connected to the cable guide 5, allowing for lateral positioning adjustment of the cable guide 5 and flexible adjustment of its lateral position. Each component is equipped with an adjustable connection structure. The positioning device allows for positional adjustment of the cable guide 5 at different locations, facilitating fine-tuning during construction to meet the needs of various installation environments and significantly improving construction efficiency and accuracy. The adjustability and stability of this positioning device meet the requirements of complex construction environments, ensuring project safety. It effectively solves the problems of repeated measurements and inconvenient adjustments inherent in traditional methods.
