AI Technical Summary
In the existing technology, the inner formwork of the hanging basket has a complex structure, which is inconvenient to install and disassemble. When the hanging basket moves as a whole, the inner formwork rubs severely with the inner arm of the box girder, resulting in great difficulty in movement and wear of the formwork.
The system employs a support truss, an inner top mold, an inner side mold, an adjusting mold, and a rotating mechanism. The inner side mold and the adjusting mold are driven to rotate around the inner top mold by hydraulic cylinders. Combined with the adjusting assembly and the wire winding and unwinding assembly, the width of the inner mold is automatically adjusted to avoid contact with the inner wall of the box girder.
It achieves a compact structure for the inner formwork of the hanging basket, which is easy to install and disassemble, reduces frictional resistance, improves movement efficiency and accuracy, and adapts to the casting requirements of variable cross-section box girders.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of hanging basket construction for railway bridges, and particularly relates to an inner formwork for a hanging basket for cast-in-place beams. Background Technology
[0002] Because high-speed trains travel at extremely high speeds, elevated bridges are often used in their construction to maintain the straightness and stability of the tracks. During the construction of these elevated bridges, the hanging basket method is generally employed. In the construction of cantilever bridges with large spans, the bridge structure between the two bridge supports is a variable cross-section box girder.
[0003] The process of formwork casting is as follows: after the formwork is installed in section 1, section 2 is poured. After section 2 is completed and reaches the specified strength value, the formwork is moved. Before moving the formwork, demolding is required. In existing technologies, the inner formwork is mostly a custom-made template, connected to the truss. The template is partially or completely removed manually to prevent it from directly contacting the inner wall of the box girder, allowing for smooth movement. Once moved to the designated position, the template is positioned and installed. Due to the change in the cross-section of the box girder, the dimensions of the newly installed template must be changed and refitted. The process of demolding the inner formwork and installing the new template is cumbersome and the accuracy is unstable. During installation, the templates on both sides cannot be installed simultaneously, and the low accuracy increases the difficulty of subsequent elevation adjustments. In addition, when the template is moved directly, friction occurs at the contact point between the template and the inner wall of the box girder, making it difficult to move and causing wear to the template. Summary of the Invention

Detailed Implementation
[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Please see Figure 1-10 This invention provides a technical solution for the inner formwork of a cast-in-place beam hanging basket:
[0030] A cast-in-place beam hanging basket inner formwork includes a support truss 4, an inner top formwork 7, inner side formwork 8, and an adjusting formwork 10. The inner top formwork 7 is provided in one piece and is fixedly connected to the support truss 4 by bolts. The support truss 4 is located in the middle of the inner side of the inner top formwork 7 and is slidably mounted on the sliding beam 3 of the hanging basket body 2. There are two inner side formworks 8, which are symmetrically arranged about the inner top formwork 7. The two inner side formworks 8 are rotatably connected to both sides of the inner top formwork 7. In the working state, the inner top formwork 7 and the two inner side formworks 8 form a gate shape. A connecting mold 9 is provided between the inner mold 8 and the inner top mold 7. The connecting mold 9 is fixed to the inner mold 8 and forms an angle greater than 90°. The connecting mold 9 is rotatably connected to the inner top mold 7. An adjusting mold 10 is rotatably provided on the side of the inner mold 8 away from the inner top mold 7. A torsion spring is provided at the rotation axis of the adjusting mold 10 and the inner mold 8. Under the action of the torsion spring, the adjusting mold 10 rotates around the rotation axis and forms an angle with the inner mold 8.
[0031] The length of the adjusting mold 10 along the width direction of the inner mold 8 is affected by the angle between the inner mold 8 and the inner top mold 7. Specifically, there are two scenarios: First, when the angle between the inner mold 8 and the inner top mold 7 decreases, the length of the adjusting mold 10 along the width direction of the inner mold 8 decreases; subsequently, when the angle between the inner mold 8 and the inner top mold 7 increases again, the length of the adjusting mold 10 along the width direction of the inner mold 8 remains unchanged. Second, when the angle between the inner mold 8 and the inner top mold 7 decreases, the length of the adjusting mold 10 along the width direction of the inner mold 8 remains unchanged; subsequently, when the angle between the inner mold 8 and the inner top mold 7 increases again, the length of the adjusting mold 10 along the width direction of the inner mold 8 increases.
[0032] The adjusting mold 10 is composed of multiple template units 11, which are arranged sequentially along its width direction to form the adjusting mold 10. A torsion spring is provided at the rotation axis between two adjacent template units 11. Under the action of the torsion spring, an angle is formed between adjacent template units 11. In this embodiment, four template units 11 are provided. The length adjustment of the adjusting mold 10 along the width direction of the inner mold 8 is achieved by restricting the rotation of adjacent template units 11.
[0033] A mounting frame 6 is vertically mounted on the supporting truss 4. Multiple mounting frames 6 are arranged longitudinally along the supporting truss 4, and the mounting frames 6 are located at the longitudinal centerline. In this embodiment, four mounting frames 6 are arranged at equal intervals. A rotation mechanism for driving the inner mold 8 and the adjusting mold 10 to rotate around the inner top mold 7 is provided between the inner mold 8 and the mounting frame 6. The rotation mechanism includes a drive rod 12, a connecting frame 13, and a hydraulic cylinder 14. The drive rod 12 is longitudinally arranged inside the mounting frame 6 and slides along the vertical direction of the mounting frame 6. The hydraulic cylinder 14 is fixed on the supporting truss 4, and the output end of the hydraulic cylinder 14 is connected to the drive rod 12. Two connecting frames 13 are provided, and the two connecting frames 13 are respectively arranged on both sides of the drive rod 12. One end of the connecting frame 13 is rotatably connected to the inner mold 8, and the other end is rotatably connected to the drive rod 12. When in operation, the output end of the hydraulic cylinder 14 is at its maximum length. When the output end of the hydraulic cylinder 14 retracts, it drives the drive rod 12 to move toward the inner top mold 7. Under the action of the connecting frame 13, the two inner molds 8 rotate around the inner top mold 7 at the same time, and the included angle between the inner mold 8 and the inner top mold 7 becomes smaller.
[0034] In order to adjust the length of the adjusting mold 10 along the width direction of the inner mold 8 while the included angle between the inner mold 8 and the inner top mold 7 changes, an adjusting mechanism is provided between the adjusting mold 10 and the inner mold 8.
[0035] The adjustment mechanism includes an adjustment assembly 15, a connecting plate 22, a traction steel wire 23, and a wire take-up and release assembly 24. The adjustment assembly 15 is disposed between the adjustment mold 10 and the inner mold 8. Multiple adjustment assemblies 15 are evenly spaced along the length of the adjustment mold 10. In this embodiment, three sets of adjustment assemblies 15 are evenly spaced along the length of the adjustment mold 10. The adjustment assembly 15 includes an adjustment plate 16, a sliding seat 17, a sliding rod 18, and a spring 19. The sliding seat 17 is fixedly disposed on the inner mold 8. The adjustment plate 16 is slidably disposed within the sliding seat 17 and slides along the width of the adjustment mold 10. The lower end of the adjustment plate 16 is an arc-shaped plate. The adjustment plate 16 is in contact with the inner surface of the template unit 11. An ear seat 20 is fixedly disposed on the sliding seat 17, and a connecting seat 21 is disposed on the adjustment plate 16. One end of the sliding rod 18 is fixedly mounted on the connecting seat 21, and the other end passes through the ear seat 20. The sliding rod 18 is parallel to the adjusting plate 16. The spring 19 is sleeved on the sliding rod 18 and is located between the connecting seat 21 and the ear seat 20. The connecting plate 22 connects multiple adjusting plates 16 together. One end of the traction wire 23 is connected to the connecting plate 22, and the other end is connected to the wire take-up and release assembly 24. The traction wire 23 is set along the width direction of the inner mold 8 and the inner top mold 7. Fixed pulleys are set on the inner mold 8 and the inner top mold 7. A guide rod 5 is vertically fixed on the support truss 4. A fixed pulley is set at the end of the guide rod 5. The traction wire 23 is laid along the fixed pulley. The traction wire 23 passes through the inner mold 8, the inner top mold 7 and the fixed pulley set on the guide rod 5 in sequence and then connects to the wire take-up and release assembly 24. Due to the action of the adjusting plate 16, all template units 11 and the inner mold 8 are in the same plane. When the traction wire 23 is pulled by the wire take-up and release assembly 24, the adjusting plate 16 slides along the sliding seat 17 and the spring 19 is compressed. As the adjusting plate 16 is no longer in contact with the template unit 11, the template unit 11 rotates under the action of the torsion spring, which reduces the actual length of the adjusting mold 10 in the width direction of the inner mold 8.
[0036] The wire winding and unwinding assembly 24 is used to wind up or unwind the traction wire 23. The drive rod 12 is a rotating shaft. A bushing 25 is slidably installed inside the mounting frame 6. The rotating shaft is rotatably installed inside the bushing 25. The output end of the hydraulic cylinder 14 is fixed on the bushing 25. The wire winding and unwinding assembly 24 is installed on the drive rod 12. The wire winding and unwinding assembly 24 includes a drum 26, a rack 27, a first ratchet 28, a gear 29, a first brake block 30, and a reversing element 31. The drum 26 is coaxially installed on the rotating shaft. The end of the traction wire 23 away from the connecting plate 22 is wound around the drum 26. The rack 27 is fixedly installed on the mounting frame 6 and is arranged along the length direction of the mounting frame 6. The gear 29 is rotatably sleeved on the rotating shaft. The rack 27 meshes with the gear 29. A first receiving portion is opened on the end face of the gear 29. The shaft includes a groove 32, a first adjusting groove 33, and two first pivot grooves 34. A first ratchet 28 is coaxially mounted on the rotating shaft and is located within the first receiving groove 32. Two first braking blocks 30 are provided in the first adjusting groove 33, and the two first braking blocks 30 correspond one-to-one with the two first pivot grooves 34. The first braking blocks 30 are rotatably mounted within the first pivot grooves 34. An elastic element is provided between the first braking block 30 and the first side surface 35 of the first adjusting groove 33. In this embodiment, the elastic element is a spring. The reversing member 31 is rotatably mounted between the two first braking blocks 30. A first end cover 36 is provided on the end face of the gear 29 away from the bushing 25. The first end cover 36 is connected to the gear 29 by bolts. A first reversing notch is provided on the first end cover 36 for the reversing member 31 to rotate.
[0037] The end face of the bushing 25 away from the gear 29 is provided with a second receiving groove 37, a second adjusting groove 38, and a second pivot groove 39. A second ratchet is provided in the second receiving groove 37 and is coaxially mounted on the rotating shaft. A second braking block 40 and a limiting block 41 are provided in the second adjusting groove 38. The second braking block 40 is rotatably mounted in the second pivot groove 39, and the limiting block 41 is rotatably mounted in the second adjusting groove 38. An elastic element is provided between the second braking block 40 and the second side surface 42 of the second adjusting groove 38. In this embodiment, the elastic element is a spring. A second end cover 43 is provided on the end face of the bushing 25 away from the gear 29. The second end cover 43 is connected to the bushing 25 by bolts. A second reversing notch is provided on the second end cover 43 for the limiting block 41 to rotate.
[0038] The above-mentioned construction method for the inner formwork of cast-in-place beam hanging baskets is adopted:
[0039] Step 1: After pouring the No. 10 section of the box girder, install the main body 2 of the hanging basket and the inner formwork of the hanging basket onto the No. 0 section.
[0040] Step 2: After completing the pouring of the next section, adjust the angle between the inner mold 8 and the inner top mold 7, and shorten the actual length of the adjusting mold 10 along the width direction of the inner mold 8.
[0041] Step 3: Lower the height of the inner mold of the hanging basket.
[0042] Step 4: Move the main body 2 of the hanging basket and the inner mold of the hanging basket to the next pouring segment.
[0043] Step 5: Adjust the overall height of the inner formwork of the hanging basket, and adjust the inner formwork 8 to a vertical position before pouring the concrete for this segment.
[0044] Step 6: Repeat steps 2 to 5 to complete the overall casting of box girder 1.
[0045] Working principle: After the casting of segment 0 of box girder 1 is completed, the formwork is installed on segment 0, and then segment 1 is cast. Before casting, the installation state of the inner formwork of the formwork at the position of segment 1 is as follows: Figure 1 and Figure 9 As shown, at this time, both the inner mold 8 and the adjusting mold 10 are vertically set. The template unit 11 remains vertical under the action of the adjusting plate 16, and the output end of the hydraulic cylinder 14 is in its maximum extension state. Under the action of the connecting frame 13, the inner mold 8 remains fixed. The adjusting component 15 and the wire winding and unwinding component 24 of the adjusting mechanism are as follows: Figures 5-8 As shown, in this state, after the pouring of segment 1 is completed, the inner mold of the hanging basket is adjusted so that the main body 2 of the hanging basket and the inner mold can be moved to the pouring position of the next segment.
[0046] The process of moving the main body 2 of the hanging basket is as follows: First, the overall shape of the inner mold is adjusted by the rotation mechanism and the adjustment mechanism. Specifically, the output end of the hydraulic cylinder 14 retracts towards the hydraulic cylinder 14, driving the drive rod 12 to move towards the inner top mold 7. Under the action of the connecting frame 13, the two inner side molds 8 rotate around the inner top mold 7 simultaneously, and the included angle between the inner side mold 8 and the inner top mold 7 becomes smaller. During the above process, the output end of the hydraulic cylinder 14 drives the bushing 25 to move along the mounting frame 6, and the gear 29 rotates forward under the action of the rack 27. Figure 6 As shown, the first braking block 30 and the first ratchet 28 limit the rotation of the drive rod 12, which in turn causes the drum 26 to rotate. The drum 26 winds up the traction wire 23, thus the traction wire 23 drives the adjusting plate 16 to slide along the sliding seat 17. The spring 19 is compressed, and as the adjusting plate 16 no longer contacts the template unit 11, the template unit 11 rotates under the action of the torsion spring, causing the actual length of the adjusting mold 10 along the width direction of the inner mold 8 to decrease. Figure 10 As shown. Through the above operations, the inner mold 8 does not contact the inner wall of the box girder 1, and the template unit 11 away from the inner mold 8 rotates at a certain angle. Then, by adjusting the overall height of the sliding beam 3, the inner top mold 7 and the supporting truss 4 are moved down as a whole. Finally, the hanging basket body 2 and the inner mold are moved along the extension direction of the main body of the box girder 1 to the next casting segment. During the movement, the inner top mold 7 and the inner mold 8 do not contact the inner wall of the box girder 1, and no friction is generated during the movement.
[0047] After the main body 2 of the hanging basket moves to the next pouring segment, the overall height of the sliding beam 3 is first adjusted so that the inner top mold 7 and the supporting truss 4 are moved upward to the designated height. Then, the state of the inner side mold 8 and the adjusting mold 10 is adjusted by the rotation mechanism and the adjustment structure. The hydraulic cylinder 14 drives the bushing 25 to slide along the mounting frame 6, so that the bushing 25 moves away from the hydraulic cylinder 14. During this process, the gear 29 rotates in the opposite direction under the action of the rack 27, and the traction wire 23 has tension under the action of the spring 19 sleeved on the sliding rod 18, that is, it has the force to pull the drive rod 12 to rotate. However, if Figure 7 , Figure 8 Under the action of the second brake block 40 and the second ratchet in the current state, the traction wire 23 cannot pull the drive rod 12 to rotate. Therefore, the gear 29 drives the first brake block 30 to rotate, but the drive rod 12 as a whole cannot rotate. Therefore, the actual length of the adjusting mold 10 along the width direction of the inner mold 8 remains unchanged after the reduction. Therefore, when casting the next segment of the box girder 1, it can automatically adapt to the casting of the box girder 1 with a variable cross-section. The entire box girder 1 is cast in a cyclical manner according to the above method.
