Description

Technical Field

[0001] This invention relates to the field of curved cable tower climbing formwork construction technology, and in particular to a rotating bracket suitable for curved cable tower climbing formwork construction. Background Technology

[0002] As bridge engineering develops towards longer spans, more aesthetically pleasing designs, and higher performance, spatial curved towers, with their excellent wind resistance and vibration reduction capabilities, beautiful architectural shapes, and favorable stress characteristics, have been widely used in long-span cable-stayed bridges and suspension bridges. Traditional straight and zigzag bridge towers can no longer meet the comprehensive requirements of modern bridges for structural performance, urban landscape, and integration with regional culture. Hyperboloid, torsional gradient, and multi-curvature irregular-shaped towers are gradually becoming the mainstream design form for large bridges.

[0003] Currently, the construction of curved tower columns mostly adopts customized steel formwork combined with hydraulic climbing formwork, flipping formwork, or segmental prefabrication and assembly processes. The climbing formwork supports mostly use simple welded brackets or steel supports, which have problems such as low load-bearing capacity, insufficient safety redundancy, lack of reliable anti-fall mechanism, inconvenient disassembly and assembly, and poor versatility. They are difficult to meet the construction requirements of super high-rise buildings, large tonnage, and high synchronization. Furthermore, they cannot adapt to the changes in the curved surface of the tower column. Traditional hanging supports can no longer meet the technical requirements of modern hydraulic climbing formwork, such as high load-bearing capacity, high reliability, fast turnover, and adaptive variable cross-section.

[0004] For example, the hydraulic climbing formwork climbing posture adjustment device, hydraulic climbing formwork and posture adjustment method disclosed in patent CN107558728A require the sliding device to be fixed on the building or embedded inside the building, which is not applicable to bridge curved cable towers. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rotating support suitable for climbing formwork construction of curved cable towers. It can adapt to changes in the curved surface of the cable tower, adaptively adjust its posture, and avoid damage to components caused by local stress concentration.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: This application provides a rotating bracket suitable for the construction of curved cable tower climbing formwork. The rotating bracket is used to connect the cable tower and the climbing formwork. The rotating bracket includes a tower column side rotating support, a connecting pin, a frame body side rotating support, a wall support, and a wall support bracket for positioning the frame. The tower column side rotating support is fixed on the surface of the cable tower. The tower column side rotating support and the frame body side rotating support are movably connected by the connecting pin. The wall support is fixed on the outside of the frame body side rotating support, and the wall support bracket is clipped onto the wall support.

[0007] Further or preferred: The tower is pre-embedded with climbing cones, and the rotating support on the side of the tower column is anchored to the climbing cones by bolts.

[0008] The tower column side rotating support includes a tower column fitting plate and a hinge part provided on the outside of the tower column fitting plate. The tower column fitting plate is an arc-shaped plate that fits with the tower.

[0009] The outer side of the tower column fitting plate is provided with an upper connecting plate, a middle connecting lug and a lower connecting plate from top to bottom; the frame side rotating support includes a wall-mounted connecting plate, and the inner side of the wall-mounted connecting plate is provided with a top connecting plate, an upper connecting lug and a lower connecting lug from top to bottom; the lower connecting lug is located between the middle connecting lug and the lower connecting plate, and the upper connecting lug is located between the middle connecting lug and the upper connecting plate, and then they are connected by a connecting pin through a hinge.

[0010] The top connecting plate of the frame-side rotating support rests on the upper connecting plate of the tower column-side rotating support, and the bottom of the tower column-fitting support plate is provided with supporting ribs for supporting and reinforcing the lower connecting plate.

[0011] The wall support is a horizontal plate structure. Both ends of the horizontal plate structure are provided with wall support fixing holes, and the inner side of the middle part of the horizontal plate structure is provided with a groove for the wall support bracket to be fastened on the wall support.

[0012] The inner side of the wall-mounted bracket is provided with a hollowed-out portion to avoid the wall-mounted bracket. An upper hanging plate is provided on the inner side of the wall-mounted bracket above the hollowed-out portion, and a lower hanging plate is provided on the inner side of the wall-mounted bracket below the hollowed-out portion.

[0013] The bottom of the wall-mounted bracket is provided with a bottom positioning block corresponding to the hollow part. The bottom positioning block is provided with a positioning screw hole along the vertical direction, and a positioning bolt is provided in the positioning screw hole to lock it on the wall.

[0014] The upper outer side of the wall-mounted bracket is provided with an opening, and the inner wall of the opening of the wall-mounted bracket is provided with a side limiting part for the edge of the frame steel to be inserted.

[0015] The wall-mounted bracket has a horizontally extending hanging rod, the end of which extends from the side of the wall-mounted bracket. The hanging plate of the frame is fastened to the end of the hanging rod, and the end of the hanging rod is provided with a blocking element for limiting the position of the hanging plate.

[0016] Compared with the prior art, the present invention has the following advantages: The rotating hanger structure, suitable for climbing formwork construction of curved cable towers, is rationally designed. It can adaptively rotate around its axis to adjust the posture of the formwork, effectively compensating for various construction deviations such as guide rail installation, concrete surface, and cable tower curvature, eliminating slight tilting of the formwork, and avoiding damage to components due to local stress concentration. It can also automatically adjust the angle to accommodate cable tower taper, tilt, and arc curvature, solving problems such as force eccentricity, guide rail jamming, and climbing blockage in irregular structures such as variable cross-section high piers and cable-stayed bridge towers. It can slightly compensate for climbing angle, reducing the jamming and asynchronous climbing problems caused by structural deviations and wind loads, ensuring smooth climbing and reducing the impact on the hydraulic system.

These relative terms are for ease of description and are not generally intended to require a specific direction.

[0028] like Figures 1 to 7 As shown, this application provides a rotating bracket suitable for the construction of climbing formwork for curved cable towers. The rotating bracket structure 2 is used to connect the tower column 1 of the cable tower and the frame 3 of the climbing formwork. The rotating bracket can adaptively adjust the posture of the frame to adapt to changes in the curved surface of the cable tower.

[0029] Its rotating bracket structure 2 includes a tower-side rotating support 201, a connecting pin 202, a frame-side rotating support 203, a wall-holding bracket 204, and a wall-holding bracket 205 for frame positioning. The tower-side rotating support is fixed to the surface of the tower with high-strength bolts. The tower-side rotating support and the frame-side rotating support are movably connected by a connecting pin. The wall-holding bracket is fixed to the outside of the frame-side rotating support, and the wall-holding bracket is clipped onto the wall-holding bracket. The load-bearing tripod of the frame (climbing scaffold) is fastened to the bracket. During use, the climbing scaffold of irregularly shaped tall buildings adapts to the force and adjusts the posture of the frame through the combined force of the wall-holding bracket, the wall-holding bracket, and the rotating bracket.

[0030] The tower has a pre-embedded climbing cone, and the rotating support on the side of the tower column is anchored to the climbing cone by bolts. The climbing cone is cast inside the tower and includes a conical structure at the inner end and a threaded structure at the outer end. The conical structure inside makes the structure stable and reliable. The rotating support on the side of the tower column is fixed by bolts and threaded holes on the threaded structure, which is easy to connect.

[0031] In some embodiments, the tower column side rotation support 201 includes a tower column fitting plate 2011 and a hinge portion disposed on the outer side of the tower column fitting plate. The tower column fitting plate is an arc-shaped plate that fits against the cable tower. Preferably, the tower column fitting plate is processed into a contoured steel plate, the tower column fitting plate has good fit with the outer surface of the cable tower, the contact area between the tower column fitting plate and the cable tower is relatively large, and the fixing is stable and reliable.

[0032] The tower column fitting plate and the hinged part are welded together as a whole structure, which is stable and reliable. Preferably, the outer side of the tower column fitting plate 2011 is provided with an upper connecting plate 2012, a middle connecting lug 2013 and a lower connecting plate 2014 from top to bottom. The frame side rotating support 203 includes a wall-mounted connecting plate 2031, and the inner side of the wall-mounted connecting plate is provided with a top connecting plate 2034, an upper connecting lug 2033 and a lower connecting lug 2032 from top to bottom. The outer structure of the tower column fitting plate and the inner structure of the wall-mounted connecting plate are cross-fitted together and connected by a connecting pin through the hinge. The Z-direction bearing capacity is strong, the hinged structure is not easy to deform, and the structure is stable and reliable.

[0033] Among them, the middle connecting lug, the lower connecting lug, and the upper connecting lug are all hollow lug structures with strong load-bearing capacity; preferably, the hollow lug structure includes a horizontally arranged upper lug plate and a lower lug plate, with the upper lug plate located directly above the lower lug plate and a gap between them. The upper lug plate and the lower lug plate are welded together by a connecting sealing plate to form an integral lug structure, which is reliable.

[0034] The lower connecting lug is located between the middle connecting lug and the lower connecting plate, and the upper connecting lug is located between the middle connecting lug and the upper connecting plate. They are then connected by a connecting pin, forming a novel overall hinged structure.

[0035] Furthermore, such as Figure 2 As shown, the top connecting plate of the frame-side rotating support rests on the upper connecting plate of the tower column-side rotating support. The bottom of the tower column-fitting support plate is provided with a support rib 2015 for supporting and reinforcing the lower connecting plate. The hinged structure is not easily deformed.

[0036] In some embodiments, the wall support 204 is a horizontal plate structure, and both ends of the horizontal plate structure are provided with wall support fixing holes 2041; the wall support is arranged horizontally, and both ends of the wall support are fixed to the wall support connecting plate of the rotating support on the side of the frame by high-strength bolts.

[0037] The inner side of the middle section of the horizontal plate structure is provided with a groove for the wall-mounted bracket to be engaged with the wall-mounted bracket; that is, the wall-mounted bracket is engaged in the middle position of the wall-mounted bracket, and the end of the wall-mounted bracket is located on the side of the wall-mounted bracket, which facilitates the connection operation.

[0038] In some embodiments, the inner side of the wall-mounted bracket is provided with a hollowed-out portion to avoid the wall-mounted bracket, and the inner side of the bracket body 2051 is provided with an upper hanging plate 2052 above the hollowed-out portion, and the inner side of the wall-mounted bracket body is provided with a lower hanging plate 2053 below the hollowed-out portion. The inner upper and lower parts of the wall support are both provided with grooves with one end open; such as Figure 5 As shown, the upper inner side of the wall support is provided with an upper groove, and the lower inner side of the wall support is provided with a lower groove. The upper groove and the lower groove are aligned vertically. The upper groove and the lower groove are open at the same end, and the other end is not through.

[0039] The wall support is inserted into the hollow part, the upper hanging plate and the upper groove are matched, and the lower hanging plate and the lower groove are matched. After the matching is in place, the wall support is fixed to the rotating support on the side of the frame with high-strength bolts. The wall support is reliably positioned and the matching operation is simple.

[0040] In some embodiments, a bottom positioning block 2054 is provided at the bottom of the wall-mounted bracket corresponding to the hollowed-out portion. The bottom positioning block is located at the middle position of the bottom of the wall-mounted bracket. The bottom positioning block is provided with a positioning screw hole along the vertical direction. A positioning bolt 2055 is provided in the positioning screw hole to lock onto the wall, so that it is not easy to loosen. Furthermore, a wall-mounted bracket fixing hole is provided in the middle of the wall-mounted bracket, which is fixed by fasteners after installation.

[0041] like Figure 2 and Figure 6 as well as Figure 7 As shown, the upper outer side of the wall-mounted bracket has an opening, and the inner wall of the opening of the wall-mounted bracket has a side limiting part 2056 for the edge of the frame steel to be inserted. The side limiting part is formed by two limiting ribs arranged opposite to each other, and the two limiting ribs form an insertion area for the edge of the frame steel to be inserted. The frame is easy to insert into the wall-mounted bracket.

[0042] Furthermore, the two limiting ribs are two oppositely arranged arc-shaped ribs. The openings at the upper and lower ends of the interlocking area formed by the two arc-shaped ribs are larger than the opening in the middle, which facilitates the interlocking operation and ensures stability and reliability after interlocking.

[0043] like Figure 2 As shown, a hanging rod 206 is provided horizontally in the wall-mounted bracket. The end of the hanging rod extends from the side of the wall-mounted bracket, and the hanging plate of the frame is fastened to the end of the hanging rod, making operation simple; furthermore, the end of the hanging rod is provided with a blocking component for limiting the position of the hanging plate. The blocking component is a bent component or a pin component.

[0044] This rotating support structure, applicable to the construction of curved cable tower climbing formwork, is rationally designed. It can adaptively rotate around its axis to adjust the posture of the formwork, effectively compensating for various construction deviations such as guide rail installation, concrete surface, and cable tower curvature, eliminating slight tilting of the formwork, and avoiding damage to components due to local stress concentration. It can also automatically adjust the angle to accommodate cable tower taper, tilt, and arc curvature, solving problems such as force eccentricity, guide rail jamming, and climbing blockage in irregular structures such as variable cross-section high piers and cable-stayed bridge towers. It can slightly compensate for the climbing angle, reducing the jamming and asynchronous climbing problems caused by structural deviations and wind loads, ensuring smooth climbing and reducing the impact on the hydraulic system.

[0045] The principle of the rotating hanging seat structure applicable to the climbing formwork construction of curved cable towers is explained in detail below: The tower's interior is pre-cast with embedded climbing cones, serving as the load-bearing base for the entire rotating support. The climbing cones employ a composite structure with an inner conical end and a threaded hole at the outer end. The conical embedded structure tightly engages with the tower's concrete, significantly improving anchoring stability and preventing loosening and detachment under stress. The rotating support on the tower side is locked to the threaded hole at the outer end of the climbing cone using high-strength bolts, achieving a secure fixation between the entire support and the tower's curved surface. This ensures convenient installation and reliable anchoring, providing a stable foundation for subsequent structural stress and rotation adjustments.

[0046] The mounting adjustment structure is a cross-hinged combination of tower-side rotating supports and frame-side rotating supports. The tower-side rotating supports adopt a contoured arc-shaped fitting plate that can completely conform to the curved outer wall of the tower, increasing the contact area and adapting to the curvature characteristics of the tower. The outer side of the fitting plate integrates an upper connecting plate, middle and lower connecting lugs into a single welded structure, resulting in strong structural integrity and resistance to deformation. Corresponding connecting plates and connecting lugs are matched on the inner side of the frame-side rotating supports. The connection structures of the two sets of supports are cross-nested and hinged through a connecting pin, forming a flexible connection structure that can rotate around the pin. All connecting lugs adopt a hollow plate welded integral structure, combined with a double-layer plate design with upper and lower alignment, significantly improving the vertical load-bearing capacity in the Z direction while retaining flexible rotation adjustment margins. This allows for adaptive fine-tuning of the frame angle and posture according to changes in tower taper, tilt, and curvature. Furthermore, the tower-side supports are reinforced with supporting ribs at the bottom and overlapping limiters on the top connecting plate, further strengthening the stability of the hinged structure and preventing deformation under stress.

[0047] The wall-mounted support and wall-mounted hanger form a precise, detachable frame positioning assembly. The wall-mounted support is a horizontal plate structure, fixed to the rotating support on the side of the frame with high-strength bolts at both ends, and has a special groove in the middle; alternatively, the wall-mounted hanger has a hollowed-out fitting structure on the inner side, combined with double-layer grooves and positioning plates for precise locking onto the wall-mounted support, achieving rapid positioning and assembly. Simultaneously, the bottom of the wall-mounted hanger has a bottom positioning block with locking bolts for vertical locking and anti-loosening; the outer side has an insertion area formed by arc-shaped limiting ribs, combined with horizontal hanging rods and end blocking limiting structures, allowing for quick locking and fastening of the climbing scaffold's load-bearing tripod and frame steel, achieving rapid installation and precise positioning of the frame, effectively limiting frame offset and sway, and ensuring that the frame and the rotating adjustment structure are subjected to force and adjusted synchronously.

[0048] This rotating support structure features multi-dimensional hinged rotation and precise positioning. Through the coordinated operation of the split rotating structure, pre-embedded anchoring structure, and wall-mounted limiting structure, it achieves adaptive fine-tuning of the climbing scaffold's posture, solving the adaptability and stability challenges of climbing formwork construction for irregularly shaped high-rise structures. The overall structure mainly consists of three parts: pre-embedded anchoring components, bidirectional rotating support components, and wall-mounted connection and positioning components. These components work together to complete the functions of load-bearing and posture adjustment, ensuring structural stability and reliability.

[0049] The above description is merely an illustration of preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0050] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner.
