Description

Technical Field

[0001] This invention belongs to the field of temporary supports for steel box girders, specifically a detachable connection structure for temporary supports of steel box girders. Background Technology

[0002] Steel box girders, also known as steel plate box girders, are a common structural form for long-span bridges. They are generally used on bridges with large spans and are called steel box girders because their shape resembles a box. A steel box girder is typically constructed by welding together a top plate, bottom plate, web, transverse diaphragms, longitudinal diaphragms, and stiffening ribs. The top plate is an orthogonal irregular bridge deck composed of a cover plate and longitudinal stiffening ribs.

[0003] When steel box girders are erected above the road, the construction of the steel box girders takes a long time because the road below is in use. Therefore, piers are set up on both sides of the road, and then temporary supports and jacking supports are set up on both sides of the road. The steel box girders that should have been placed above the road are first assembled on the piers and supports on one side of the road. Then, the assembled steel box girders are moved from above the road to the piers on the other side by jacking supports. This operation can be carried out while the road below is in normal traffic.

[0004] Because of the large volume and mass of the steel box girder, the bridge deck is traditionally moved in two stages. Therefore, during the two stages of the movement, temporary supports need to be erected on one side first, then dismantled. After moving a certain distance, the temporary supports are erected again and the movement is carried out again. If the overall structure between the temporary supports is connected by bolts or welding, the dismantling process will be time-consuming.

[0005] Therefore, the present invention provides a detachable connection structure for temporary support of steel box girders. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A detachable connection structure for a temporary support of a steel box girder, comprising a support top frame, with multiple sets of support beams connected to the bottom of the support top frame. Each set of support beams consists of a first support column and a second support column, which are arranged in parallel. The support top frame is formed by splicing two I-beams end-to-end. Two sets of parallel telescopic top columns are provided at the top of the support top frame. Adjacent sets of support beams are connected to each other via connecting components. A separation component connects the support top frame and the multiple sets of support beams. The separation component is used to separate the support top frame from the multiple support beams. A buffer spring is provided inside the telescopic top column. During operation, the support top frame is supported by the first and second support columns. The structure has a large load-bearing capacity and can stably support large-mass steel box girders. The first and second support columns are used to support the top frame. The telescopic top columns can be adjusted in height so that the top surfaces of multiple telescopic top columns can be kept horizontal. Traditional jacking supports generally need to first lift, then push horizontally a certain distance, lower, and repeat to complete the movement of the steel box girder. The buffer spring can play a buffering role during the slow advancement of the steel box girder. After the steel box girder on one side has moved, the top frame is separated from the first and second support columns by the separation component, so that the top frame can be disassembled individually. After the top frame is hoisted down, the connecting component is opened to separate each group of support beams from each other. This allows for the rapid disassembly of the entire temporary structure, which is helpful for the subsequent movement process.

[0008] Preferably, a separating top seat is fixedly connected to the top of the first support column, and a tilting top seat is fixedly connected to the top of the second support column. The bottom of the support frame is provided with a docking groove that matches the separating top seat and the tilting top seat. The bottom of both the first and second support columns is fixedly connected to a base. During operation, the bottom surface of the support frame engages the separating top seat and the tilting top seat through the docking groove to make them stably connected. The base needs to be connected to the foundation to ensure the stability of the overall support.

[0009] Preferably, the separation assembly includes a hydraulic rod. A through hole extending to the inner side of the first support column is provided in the center of the separation top seat. The hydraulic rod is fixed to the inner side of the through hole. An elastic pad is connected to the top of the hydraulic rod. A rotating groove is provided on the top surface of the side-tilting top seat. A side-tilting plate is provided in the rotating groove. A reduction motor for driving the side-tilting plate to rotate is connected to the outer side of the side-tilting plate. A traction assembly is provided on the outer side of the second support column. The traction assembly is used to slowly lower the support top frame. During operation, when the support top frame needs to be separated, the hydraulic rod is activated to push it outwards. Simultaneously, the reduction motor on the outer side of the side-tilting top seat is activated to drive the side-tilting plate to rotate, allowing the support top frame to rotate around the side-tilting plate as a rotation axis. The elastic pad at the top of the hydraulic rod can deform appropriately to ensure that the contact surface adheres to the support top frame during the pushing process. During the rotation of the support top frame, the traction assembly ensures the stability of the rotation. Furthermore, when the support top frame rotates to vertical, the traction assembly can slowly release the support top frame downwards, thus eliminating the need for cranes or other equipment to transport the support top frame downwards.

[0010] Preferably, a clamping plate is fixed to the top surface of the side flap pair to restrict the side of the support frame. Multiple reinforcing steel pipes are connected between each set of first and second support columns. During operation, the clamping plate is used to block the side of the support frame so that the support frame will not slide outward during rotation. The reinforcing steel pipes are used to increase the connection strength between the first and second support columns.

[0011] Preferably, the traction assembly includes a second suspension cable. One end of the second suspension cable is connected to the side of the support frame via a connecting bolt. A first reduction motor is fixedly connected to the top of the second support column. The other end of the second suspension cable is wound and fixedly connected to the output end of the second reduction motor. During operation, the second suspension cable continuously tightens as the support frame rotates. When the support frame rotates to a vertical position, it will be parallel to the second support column. Then, by continuously releasing multiple second suspension cables, the support frame can be lowered to the bottom.

[0012] Preferably, the traction assembly further includes a first suspension cable, and a second reduction motor is fixedly connected to the top of the second support column. One end of the first suspension cable is wound and connected to the output end of the second reduction motor. Multiple connecting rings are fixedly connected to the outer side of the support top frame, and the other end of the first suspension cable is connected to the connecting rings. During operation, in order to ensure the stable lowering of the support top frame, the first suspension cable is used for traction on the other side. In this way, during the rotation, the support top frame can remain in contact with the side flap and eventually rotate to a vertical state. Then, under the double fixation of the first and second suspension cables, it is slowly and stably lowered. After the lowering is completed, the ends of the first and second suspension cables are removed from the outer side of the support top frame, and the support top frame can be removed. At the same time, the first and second suspension cables can also be tightened after the support top frame is installed to reinforce the connection between the support top frame and the first and second support columns.

[0013] Preferably, the connecting assembly includes multiple merging clips, and multiple sets of connecting frames are provided between adjacent support beams. Each set of connecting frames consists of four frames, which are respectively fixed to the outside of the adjacent first and second support columns. The merging clips are connected between the ends of adjacent connecting frames, and a series rod is fixed between the merging clips on the same side. During operation, after multiple sets of support beams are erected, the adjacent connecting frames are aligned with each other, and then the merging clips are used to fix the adjacent connecting frames to further reinforce the bottom support stability of the entire temporary structure.

[0014] Preferably, a slot is provided on one side of the second support column, and a docking seat is slidably engaged in the slot. The docking seat is used to support the top support frame. During operation, in order to ensure that the top support frame can be stably suspended and lowered after being rotated, when the top support frame is rotated to a vertical position, the telescopic top column at the top will press against the docking seat. Then, during the lowering process of the top support frame, the docking seat will slide along with it. Since the docking seat is slidably engaged, the top support frame and the docking seat are pressed and fitted together, so it can move stably during the lowering process.

[0015] Preferably, the docking seat includes two docking platforms, with a series steel frame fixed between the two docking platforms. An adapter platform is fixed to the outer surface of one of the docking platforms. During operation, the adapter platform is set so that the support top frame is not in a completely vertical state, but forms a triangle with the docking seat. This avoids instability between the support top frame and the side flap when rotating to a vertical state. In this state, the support top frame can exert a force to compress the docking seat, ensuring that the two fit together during the sliding process.

[0016] Preferably, the surfaces of the other docking platform and the adapter platform are both fixed with compression pads made of elastic material. Multiple support wheels are connected to the outside of the first support column. The compression pads are designed to ensure that the contact surfaces are not in rigid contact, but have a large contact surface. The support wheels allow the first support column and the second support column to move sideways when they move.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The present invention discloses a detachable connection structure for a temporary support for a steel box girder. Through the installation of a first support column and a second support column, the support top frame structure has a large load-bearing capacity and can stably support a large-mass steel box girder. The first and second support columns are used to support the support top frame. The telescopic top column can be adjusted in height, allowing the top surfaces of multiple telescopic top columns to remain horizontal. Traditional jacking supports generally require first lifting, then pushing horizontally a distance, lowering, and repeating to complete the movement of the steel box girder. The buffer spring can play a buffering role during the slow advancement of the steel box girder. After one side of the steel box girder has moved, the support top frame is separated from the first and second support columns by a separation component, allowing the support top frame to be disassembled individually. After the support top frame is lowered, the connection component is opened to separate each group of support beams. This allows for rapid disassembly of the entire temporary support, facilitating subsequent movement.

[0019] 2. The detachable connection structure of the temporary support for steel box girder described in this invention allows for the disassembly of the support top frame. When the support top frame needs to be disassembled, the hydraulic rod is activated to push it outward, and at the same time, the reduction motor on the outside of the side-tilting top seat is activated to drive the side-tilting plate to rotate, allowing the support top frame to rotate around the side-tilting plate as the rotation axis. The elastic pad at the top of the hydraulic rod can deform appropriately to ensure that the contact surface is in contact with the support top frame during the pushing process. During the rotation of the support top frame, the traction component ensures the stability of the rotation. At the same time, when the support top frame rotates to vertical, the traction component can also slowly release the support top frame downward, thus eliminating the need to use cranes or other equipment to transport the support top frame downward.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1 to 3 As shown in the embodiment of the present invention, a detachable connection structure for a temporary support for a steel box girder includes a support top frame 1. The bottom of the support top frame 1 is connected to multiple sets of support beams. Each set of support beams consists of a first support column 2 and a second support column 3. The first support column 2 and the second support column 3 are arranged in parallel. The support top frame 1 is formed by splicing two I-beams end to end. The top of the support top frame 1 is provided with two sets of parallel telescopic top columns 4. Adjacent sets of support beams are connected to each other by connecting components. A separation component is connected between the support top frame 1 and the multiple sets of support beams. The separation component is used to separate the support top frame 1 and the multiple support beams. A buffer spring is provided inside the telescopic top column 4.

[0030] Because of the large volume and mass of the steel box girder, the bridge deck is traditionally moved in two stages. Therefore, during the two stages of the movement, temporary supports need to be erected on one side first, then dismantled. After moving a certain distance, the temporary supports are erected again and the movement is carried out again. If the overall structure between the temporary supports is connected by bolts or welding, the dismantling process will be time-consuming.

[0031] During operation, the support frame 1 has a large load-bearing capacity due to the setting of the first support column 2 and the second support column 3, which can stably support the large mass of the steel box girder. The first support column 2 and the second support column 3 are used to support the support frame 1. The telescopic column 4 can be adjusted in height so that the top surfaces of multiple telescopic columns 4 can be kept horizontal. Traditional jacking supports generally need to first lift up, then push horizontally a distance, put down, and repeat to complete the movement of the steel box girder. The setting of the buffer spring can play a buffering role during the slow advancement of the steel box girder. After the steel box girder on one side has moved, the support frame 1 is separated from the first support column 2 and the second support column 3 by the separation component, so that the support frame 1 can be disassembled individually. After the support frame 1 is hoisted down, the connecting component is opened to separate each group of support beams from each other. This allows for the rapid disassembly of the entire temporary structure, which is helpful for the subsequent movement process.

[0032] like Figures 1 to 3 As shown, a separation top seat 5 is fixedly connected to the top of the first support column 2, and a side-flipping top seat 17 is fixedly connected to the top of the second support column 3. A docking groove adapted to the separation top seat 5 and the side-flipping top seat 17 is opened at the bottom of the support top frame 1. A base 8 is fixedly connected to the bottom of both the first support column 2 and the second support column 3.

[0033] During operation, the bottom surface of the supporting top frame 1 engages the separating top seat 5 and the side-tilting top seat 17 through the docking groove to ensure a stable connection. The base 8 needs to be connected to the foundation to ensure the stability of the overall support.

[0034] like Figures 1 to 4 As shown, the separation assembly includes a hydraulic rod. The separation top seat 5 has a through hole in the middle that extends to the inner side of the first support column 2. The hydraulic rod is fixed to the inner side of the through hole. An elastic pad is connected to the top of the hydraulic rod. A rotating groove is provided on the top surface of the side-tilting top seat 17. A side-tilting plate 15 is provided in the rotating groove. A reduction motor for driving the side-tilting plate 15 to rotate is connected to the outer side of the side-tilting plate 15. A traction assembly is provided on the outer side of the second support column 3. The traction assembly is used to slowly lower the support top frame 1.

[0035] During operation, when it is necessary to disassemble the support top frame 1, the hydraulic rod is activated to push it outward. At the same time, the reduction motor on the outside of the side tilting top seat 17 is activated to drive the side tilting plate 15 to rotate, so that the support top frame 1 rotates around the side tilting plate 15 as the rotation axis. The elastic pad at the top of the hydraulic rod can deform appropriately to ensure that the contact surface is in contact with the support top frame 1 during the pushing process. During the rotation of the support top frame 1, the traction component ensures the stability of the rotation. At the same time, when the support top frame 1 rotates to the vertical position, the traction component can also slowly release the support top frame 1 downward, so that it is not necessary to use cranes or other equipment to transport the support top frame 1 downward.

[0036] like Figures 1 to 4 As shown, a clamping plate for limiting the side of the support frame 1 is fixed on the top surface of the side flap 15 pairs, and multiple reinforcing steel pipes 13 are connected between each group of first support column 2 and second support column 3.

[0037] During operation, the clamping plate is used to block the side of the support top frame 1, so that the support top frame 1 will not slide outward during rotation. The reinforcing steel pipe 13 is used to increase the connection strength of the first support column 2 and the second support column 3.

[0038] like Figures 1 to 6As shown, the traction assembly includes a second suspension cable 16. One end of the second suspension cable 16 is connected to the side of the support frame 1 via a connecting bolt. A first reduction motor is fixedly connected to the inside of the second support column 3 near the top. The other end of the second suspension cable 16 is wound and fixedly connected to the output end of the second reduction motor.

[0039] During operation, as the supporting top frame 1 rotates, the second suspension cable 16 continuously tightens. When the supporting top frame 1 rotates to a vertical position, it will be parallel to the second support column 3. Then, by continuously releasing the multiple suspension cables 16, the supporting top frame 1 can be lowered to the bottom.

[0040] like Figures 1 to 6 As shown, the traction assembly also includes a suspension cable 14. A second reduction motor is fixedly connected to the top of the second support column 3. One end of the suspension cable 14 is wound and connected to the output end of the second reduction motor. Multiple connecting rings 23 are fixedly connected to the outside of the support top frame 1. The other end of the suspension cable 14 is connected to the connecting ring 23.

[0041] During operation, to ensure the stable lowering of the support frame 1, a suspension cable 14 is used on the other side for traction. This ensures that the support frame 1 remains in contact with the side flap 15 during rotation and eventually rotates to a vertical position. Then, under the double fixation of suspension cable 14 and suspension cable 16, it is lowered slowly and stably. After lowering, the ends of suspension cables 14 and 16 are removed from the outside of the support frame 1, allowing the support frame 1 to be removed. At the same time, suspension cables 14 and 16 can be tightened after the support frame 1 is installed to reinforce the connection between the support frame 1 and the first support column 2 and the second support column 3.

[0042] like Figures 1 to 4 As shown, the connecting assembly includes multiple merging clips 7, and multiple sets of connecting frames 6 are arranged between adjacent support beams. Each set of connecting frames 6 has four frames. The four connecting frames 6 are respectively fixed to the outside of the adjacent first support column 2 and second support column 3. The merging clips 7 are connected between the ends of adjacent connecting frames 6, and a series rod 11 is fixed between the merging clips 7 on the same side.

[0043] During operation, after multiple sets of support beams are erected, align the adjacent connecting frames 6 with each other, and then use the merging clamps 7 to fix the adjacent connecting frames 6 to further reinforce the stability of the bottom support of the entire temporary structure.

[0044] like Figures 1 to 4 As shown, a slot 24 is provided on one side of the second support column 3, and a docking seat 9 is slidably engaged in the slot 24. The docking seat 9 is used to support the top support frame 1.

[0045] During operation, in order to ensure that the support top frame 1 can be stably suspended and lowered after being flipped, when the support top frame 1 is rotated to a vertical position, the top telescopic top column 4 will press and contact with the docking seat 9. Then, during the lowering process of the support top frame 1, the docking seat 9 will slide along with it. Since the docking seat 9 is a sliding snap-fit, the support top frame 1 and the docking seat 9 are pressed and fitted together, so it can move stably during the lowering process.

[0046] like Figures 1 to 6 As shown, the docking seat 9 includes two docking platforms 18, and a series steel frame 21 is fixedly connected between the two docking platforms 18. An adapter platform 20 is fixedly connected to the outer surface of one of the docking platforms 18.

[0047] During operation, the adapter platform 20 is set so that the support top frame 1 is not in a completely vertical state, but forms a triangle with the docking seat 9. This avoids the instability of the connection between the support top frame 1 and the side flip plate 15 when rotating to a vertical state. In this state, the support top frame 1 can exert a force to squeeze the docking seat 9, ensuring that the two fit together during the sliding process.

[0048] like Figures 1 to 6 As shown, the surfaces of the other docking platform 18 and the adapter platform 20 are both fixed with elastic material compression pads 19. Multiple support wheels 22 are connected to the outside of the first support column 2. The compression pads 19 are designed to ensure that the contact surfaces are not in rigid contact, but have a large contact surface. The support wheels 22 allow the first support column 2 and the second support column 3 to move sideways when they move.

[0049] During operation, the support frame 1 has a large load-bearing capacity due to the setting of the first support column 2 and the second support column 3, which can stably support the large mass of the steel box girder. The first support column 2 and the second support column 3 are used to support the support frame 1. The telescopic top column 4 can be adjusted in height so that the top surfaces of multiple telescopic top columns 4 can be kept horizontal. Traditional jacking supports generally need to lift first, then push horizontally a distance, put down, and repeat to complete the movement process of the steel box girder. The setting of the buffer spring can play a buffering role during the slow advancement of the steel box girder. After the steel box girder on one side has moved, the support frame 1 is separated from the first support column 2 and the second support column 3 by the separation component, so that the support frame 1 can be disassembled individually. After the support frame 1 is hoisted down, the connecting component is opened to separate each group of support beams from each other. This allows for the rapid disassembly of the entire temporary structure, which is helpful for the subsequent movement process.

[0050] The bottom surface of the supporting top frame 1 is connected to the separating top seat 5 and the side-tilting top seat 17 by a docking groove, so that they are stably connected. The base 8 needs to be connected to the foundation to ensure the stability of the overall support.

[0051] When it is necessary to disassemble the support top frame 1, the hydraulic rod is activated to push it outward. At the same time, the reduction motor on the outside of the side tilting top seat 17 is activated to drive the side tilting plate 15 to rotate, so that the support top frame 1 rotates around the side tilting plate 15 as the rotation axis. The elastic pad at the top of the hydraulic rod can deform appropriately to ensure that the contact surface is in contact with the support top frame 1 during the pushing process. During the rotation of the support top frame 1, the traction component ensures the stability of the rotation. At the same time, when the support top frame 1 rotates to the vertical position, the traction component can slowly release the support top frame 1 downward. In this way, it is not necessary to use cranes or other equipment to transport the support top frame 1 downward.

[0052] The clamping plate is used to block the side of the support top frame 1 so that the support top frame 1 will not slide outward during rotation. The reinforcing steel pipe 13 is used to increase the connection strength of the first support column 2 and the second support column 3.

[0053] During the rotation of the support top frame 1, the second suspension steel cable 16 is continuously tightened. When the support top frame 1 rotates to a vertical state, it will be parallel to the second support column 3. Then, by continuously releasing the multiple suspension steel cables 16, the support top frame 1 can be lowered to the bottom.

[0054] To ensure the stable lowering of the support frame 1, a suspension cable 14 is used on the other side for traction. This ensures that the support frame 1 remains in contact with the side flap 15 during rotation and eventually rotates to a vertical position. Then, under the double fixation of suspension cable 14 and suspension cable 16, it is lowered slowly and steadily. After the lowering is completed, the ends of suspension cables 14 and 16 are removed from the outside of the support frame 1, allowing the support frame 1 to be removed. At the same time, suspension cables 14 and 16 can be tightened after the support frame 1 is installed to reinforce the connection between the support frame 1 and the first support column 2 and the second support column 3.

[0055] After multiple sets of support beams are erected, align the adjacent connecting frames 6 with each other, and then use the merging clamps 7 to fix the adjacent connecting frames 6 to further reinforce the bottom support stability of the entire temporary structure.

[0056] In order to ensure that the support frame 1 can be stably suspended and lowered after being flipped, when the support frame 1 is rotated to a vertical position, the telescopic top column 4 at the top will press against the docking seat 9. Then, during the lowering process of the support frame 1, the docking seat 9 will slide along with it. Since the docking seat 9 is a sliding snap-fit, the support frame 1 and the docking seat 9 are pressed and fitted together, so it can move stably during the lowering process.

[0057] The adapter platform 20 is designed so that the support top frame 1 is not in a completely vertical state, but forms a triangle with the docking seat 9. This avoids the instability of the connection between the support top frame 1 and the side flip plate 15 when rotated to a vertical state. In this state, the support top frame 1 can exert a force to squeeze the docking seat 9, ensuring that the two fit together during the sliding process.
