Description

Technical Field

[0001] This application relates to the field of continuous beam casting technology, and in particular to a temporary consolidation device for cast-in-place continuous beam structures. Background Technology

[0002] A bridge consists of two parts: piers and beams. The top of the piers is equipped with pad stones to support the beams. As bridges develop towards longer spans, cantilever structures, and high piers, long-span bridges often adopt cantilever construction using hanging baskets. During the construction of continuous beams (bridges with three or more intermediate supports), certain unbalanced bending moments will be generated due to uncertainties such as different working conditions, construction management, and human operation. To prevent overturning during the cantilever construction process, the beams and piers need to be temporarily anchored before construction.

[0003] The existing technical solutions mentioned above have the following drawbacks: Currently, most common temporary fixing devices for large-span continuous beam piers are temporarily fixed by welding or other methods, which makes it very difficult to dismantle the temporary supports and causes great inconvenience to the staff. Utility Model Content

[0004] This application provides a temporary consolidation device for cast-in-place continuous beams to facilitate the disassembly of the temporary consolidation device.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0006] The temporary consolidation device for cast-in-place continuous beams includes two support plates stacked between the beam and the pier. An adjustment structure is provided between the two support plates to move them closer or further apart. Positioning holes are provided on the adjacent surfaces of the pier and the beam. The support plates are connected to positioning rods of the same number as the positioning holes. The positioning rods can slide into the positioning holes to limit the position of the support plates on the pier and the beam.

[0007] By adopting the above scheme, when a temporary consolidation device is required, two support plates are placed between the beam and the pier, and the positioning rod is aligned with the positioning hole. Then, when the adjustment structure is used, the distance between the two support plates is increased, and the positioning rod is inserted into the positioning hole, thereby realizing the installation of the temporary consolidation device. When the temporary consolidation device needs to be removed, the distance between the two support rods is reduced by using the adjustment structure, and the positioning rod slides out of the positioning hole, allowing the operator to easily remove the adjustment structure, thus making the disassembly of the temporary consolidation device more convenient.

[0008] Optionally, the adjustment structure includes a threaded column and a support tube, with the threaded column and support tube respectively connected to the surfaces of two support plates. An internal threaded sleeve is rotatably connected to the end of the support tube opposite to the end connected to the support plate, and the threaded column and the internal threaded sleeve are threadedly connected.

[0009] By adopting the above scheme, the operator can rotate the internal threaded sleeve, which drives the threaded column to move along the axial direction, thereby driving the support plate to move, thus achieving the purpose of adjusting the distance between the two support plates.

[0010] Optionally, a rectangular rod is provided inside the support tube, and the rectangular rod is fixedly connected to the support plate. A rectangular groove is provided at the end of the threaded column opposite to the end connected to the support plate, and the rectangular column is slidably connected in the rectangular groove.

[0011] By adopting the above scheme, the rectangular column restricts the rotation of the threaded column, preventing the threaded column from rotating and making the transmission of the adjustment structure smoother.

[0012] Optionally, the internal threaded sleeve is fixedly connected to a worm gear, and the support plate connected to the support tube is rotatably connected to a worm, which meshes with the worm gear.

[0013] By adopting the above solution, the operator can rotate the worm gear to drive the worm wheel to rotate, thereby driving the internal threaded sleeve to rotate, which in turn drives the threaded column to move, thereby adjusting the distance between the two support plates.

[0014] Optionally, the support plate is connected to a locking structure for locking the worm gear. The locking structure includes a first clamping plate and a second clamping plate. A slide rail is provided on the surface of the support plate connecting the support tube. Both the first clamping plate and the second clamping plate are connected to sliders. The first clamping plate and the second clamping plate are located on opposite sides of the worm gear. A bidirectional lead screw is rotatably connected inside the slide rail. Both sliders have threaded holes with opposite directions of rotation. Both sliders are threadedly connected to the bidirectional lead screw.

[0015] By adopting the above scheme, after the distance between the two support plates is adjusted, the operator can rotate the bidirectional lead screw to bring the two sliders closer to each other, that is, the first clamping plate and the second clamping plate get closer to each other, until the first clamping plate and the second clamping plate clamp the worm gear, thus preventing the worm gear from rotating due to external force.

[0016] Optionally, the support rod has a through hole on its surface, the positioning rod passes through the through hole and is slidably connected in the through hole, and the support plate is connected to a drive structure that drives the positioning rod to slide in the through hole.

[0017] By adopting the above scheme, after setting the two support plates between the two beams and bridge segments, the through holes are aligned with the positioning holes. The driving structure drives the positioning rod to slide in the through holes, so that the positioning rod is inserted into the positioning hole, making it easier for the operator to insert the positioning rod into the positioning hole.

[0018] Optionally, the drive structure includes a threaded rod, which is rotatably connected to the support plate and is perpendicular to the support plate. A connecting plate is fixedly connected to the end of the positioning plate away from the positioning hole. A threaded hole is provided on the surface of the connecting plate, and the threaded rod passes through the threaded hole and is threadedly connected to the connecting plate.

[0019] By adopting the above solution, the operator can rotate the threaded rod to move the connecting plate along the axis of the threaded rod, thereby causing the positioning rod to slide in the through hole.

[0020] Optionally, the connecting plate is rectangular, and each connecting plate is connected to four positioning rods, which are respectively connected to the four corners of the connecting plate.

[0021] By adopting the above scheme, one threaded rod can control four positioning rods simultaneously, making it easier for operators to adjust the positioning rods.

[0022] In summary, this application has the following technical effects:

[0023] 1. By setting up two support plates and an adjustment structure that moves the two support plates closer or further apart, it is easier for operators to remove the temporary fixing device;

[0024] 2. The addition of a worm gear and worm makes it easier for operators to drive the internal threaded sleeve;

[0025] 3. A locking structure is incorporated to prevent the worm gear from rotating due to external forces. Attached Figure Description

Detailed Implementation

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] Reference Figure 1 Figure 2 and Figure 3 The temporary consolidation device for cast-in-place continuous beams includes a support plate 1. Two support plates 1 are provided and are stacked between the beam body 8 and the pier 9. An adjustment structure 2 is provided between the two support plates 1 to move the two support plates 1 closer to or further apart from each other. Positioning holes 31 are provided on the adjacent surfaces of the pier 9 and the beam body 8. The support plate 1 is connected to a number of positioning rods 3 equal to the number of positioning holes 31. The positioning rods 3 can slide into the positioning holes 31 to limit the position of the support plate 1 on the pier 9 and the beam body 8. When a temporary consolidation device is required, two support plates 1 are placed between the beam 8 and the pier 9, and the positioning rod 3 is aligned with the positioning hole 31. Then, the distance between the two support plates 1 is increased by using the adjustment structure 2, and the positioning rod 3 is inserted into the positioning hole 31, thereby realizing the installation of the temporary consolidation device. When the temporary consolidation device needs to be removed, simply use the adjustment structure 2 to reduce the distance between the two support rods, so that the positioning rod 3 slides out of the positioning hole 31, allowing the operator to easily remove the adjustment structure 2, thus making the disassembly of the temporary consolidation device more convenient.

[0034] Reference Figure 2 The adjusting structure 2 includes a threaded column 21 and a support tube 22, which are respectively connected to the surfaces of two support plates 1. An internal threaded sleeve 221 is rotatably connected to the end of the support tube 22 opposite to its connection with the support plate 1, and the threaded column 21 is threadedly connected to the internal threaded sleeve 221. A rectangular rod 223 is installed inside the support tube 22 and is fixedly connected to the support plate 1. A rectangular groove 222 is formed at the end of the threaded column 21 opposite to its connection with the support plate 1, and the rectangular column is slidably connected within the rectangular groove 222. The operator can rotate the internal threaded sleeve 221, which drives the threaded column 21 to move along the axial direction, thereby moving the support plate 1 and achieving the purpose of adjusting the distance between the two support plates 1. The rectangular column restricts the rotation of the threaded column 21, preventing it from rotating and making the transmission of the adjusting structure 2 smoother.

[0035] Reference Figure 2 and Figure 4The internal threaded sleeve 221 is fixedly connected to a worm gear 4, and the support plate 1 connected to the support tube 22 is rotatably connected to a worm 41, which meshes with the worm gear 4. The operator can rotate the worm gear 41 to drive the worm gear 4 to rotate, thereby driving the internal threaded sleeve 221 to rotate, which in turn drives the threaded column 21 to move, thereby adjusting the distance between the two support plates 1.

[0036] Reference Figure 2 and Figure 4 The support plate 1 is connected to a locking structure 5 for locking the worm gear 41. The locking structure 5 includes a first clamping plate 51 and a second clamping plate 52. A slide rail 6 is provided on the surface of the support plate 1 connected to the support tube 22. Both the first clamping plate 51 and the second clamping plate 52 are connected to sliders 62, and the first clamping plate 51 and the second clamping plate 52 are located on opposite sides of the worm gear 41. A double-acting screw 61 is rotatably connected inside the slide rail 6. Both sliders 62 have threaded holes with opposite directions of rotation, and both sliders 62 are threadedly connected to the double-acting screw 61. After the distance between the two support plates 1 is adjusted, the operator can rotate the double-acting screw 61 to bring the two sliders 62 closer together, that is, bring the first clamping plate 51 and the second clamping plate 52 closer together, until the first clamping plate 51 and the second clamping plate 52 clamp the worm gear 41, preventing the worm gear 41 from rotating due to external force.

[0037] Reference Figure 3 and Figure 5 The support rod has a through hole 11 on its surface. The positioning rod 3 passes through the through hole 11 and is slidably connected within the through hole 11. The support plate 1 is connected to a drive structure that drives the positioning rod 3 to slide within the through hole 11. The drive structure includes a threaded rod 7, which is rotatably connected to the support plate 1 and is perpendicular to the support plate 1. A connecting plate 71 is fixedly connected to one end of the positioning plate away from the positioning hole 31. The connecting plate 71 is rectangular, and each connecting plate 71 is connected to four positioning rods 3. The four positioning rods 3 are respectively connected to the four corners of the connecting plate 71. A threaded hole is opened on the surface of the connecting plate 71, and the threaded rod 7 passes through the threaded hole and is threadedly connected to the connecting plate 71. After setting the two support plates 1 between the two beams 8 and the bridge segment, align the through hole 11 with the positioning hole 31, rotate the threaded rod 7 to drive the connecting plate 71 to move along the axis of the threaded rod 7, thereby driving the positioning rod 3 to slide in the through hole 11, so that the positioning rod 3 is inserted into the positioning hole, making it easier for the operator to insert the positioning rod 3 into the positioning hole 31.

[0038] The specific implementation principle of this application is as follows: When installing the temporary consolidation device, two support plates 1 are placed between the two beams 8 and the bridge segment. The through hole 11 is aligned with the positioning hole 31. The worm gear 41 is rotated to drive the worm wheel 4 to rotate, thereby driving the internal threaded sleeve 221 to rotate, which in turn drives the threaded column 21 to move, thereby adjusting the distance between the two support plates 1 so that the support plates 1 abut against the surface of the pier 9 and the beam 8. Then, the double-acting screw 61 is rotated so that the first clamping plate 51 and the second clamping plate 52 clamp the worm gear 41. Then, the threaded rod 7 is rotated so that the positioning rod 3 is inserted into the positioning hole 31. When removing the device, the threaded rod 7 is rotated so that the positioning rod 3 slides out of the positioning hole 31. Then, the double-acting screw 61 is rotated so that the first clamping plate 51 and the second clamping plate 52 release the worm gear 41. The worm gear 41 is rotated so that the distance between the two support plates 1 is reduced, thereby allowing the operator to easily remove the temporary consolidation device.
