Abstract
Description
Technical Field
[0001] The utility model belongs to the field of construction devices, and in particular relates to a bidirectional correction device for assembling steel box girder segments. Background Art
[0002] When assembling steel box girder segments, the gap between adjacent segments needs to be adjusted. Due to the heavy weight of a single steel box girder segment, it is difficult to adjust the gap on the assembly frame. The current common method is to use a lifting device to pull to adjust the gap between two steel box girder segments. At the same time, during the assembly process of the steel box girder, the top surfaces of adjacent segments are required to be flush. However, due to the precision error during the processing of the steel box girder and the elevation error of the top of the bracket, the top surfaces of the two steel box girder segments may be misaligned. The traditional solution is to adjust by manual tapping.
[0003] The utility model patent with publication number CN214783287U discloses a steel box girder assembly corrector, wherein the first support structure is used to be installed on one of the two adjacent steel box girder segments, the second support structure is used to be installed on the other of the two adjacent steel box girder segments, one end of the thrust device supports the first support structure, and the other end of the thrust device supports the second support structure, and the thrust device is used to push the two adjacent steel box girder segments closer to each other, and the seam width is adjusted by pushing the thrust device. The utility model patent with publication number CN212771959U discloses a steel box girder docking leveling structure, wherein the upper end of the vertical support is fixedly connected to one end of a horizontal beam, the lower end of the vertical support is welded to the top surface of the first connected steel box girder, the other end of the horizontal beam spans the docking seam between the two steel box beams, and extends above the top surface of the second steel box beam, the base of the jack is supported on the bottom surface of the horizontal beam of the reaction beam, and the front end of the piston rod of the jack is supported on the top surface of the second steel box beam.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
[0028] As a preferred embodiment of the present utility model, this embodiment provides a bidirectional correction device for assembling steel box girder segments, specifically as follows: Figure 1 The bidirectional correction device comprises a thrust device 2, a horizontal adjustment structure 3 and a vertical adjustment structure 4.
[0029] The bidirectional correction device is arranged between the first steel box girder segment 11 and the second steel box girder segment 12. The second steel box girder segment 12 is a steel box girder segment assembled after the first steel box girder segment 11, so the top surface of the first steel box girder segment 11 is lower than the second steel box girder segment 12.
[0030] The horizontal adjustment structure 3 includes an adjustment limiter 31 and a first vertical support member 32. In this embodiment, the adjustment limiter 31 is a piece of channel steel, including a web and flanges on both sides.
[0031] The adjustment limiter 31 is arranged across the gap between the top surfaces of the first steel box girder segment 11 and the second steel box girder segment 12, and the adjustment limiter 31 is fixedly connected to the second steel box girder segment 12. In this embodiment, one end of the adjustment limiter 31 is welded to the top surface of the second steel box girder segment 12, and the other end is arranged on the top surface of the first steel box girder segment 11, but is not fixedly connected.
[0032] like Figure 2 As shown, a first vertical support member 32 is vertically welded to one end of the web of the adjustment limiter 31 away from the second steel box girder segment 12. A rectangular opening 33 is provided on one end of the web of the adjustment limiter 31 close to the second steel box girder segment 12 for setting the vertical adjustment structure 4. The opening 33 spans the gap between the top surfaces of the first steel box girder segment 11 and the second steel box girder segment 12. The width of the opening 33 is slightly larger than the width of the vertical adjustment structure 4, and the length of the opening 33 is slightly larger than the length of the vertical adjustment structure 4. The vertical adjustment structure 4 includes a second vertical support member 41 and a horizontal support member 42.
[0033] like Figure 2 As shown, the second vertical support member 41 passes through the opening 33 and is vertically fixed on the top surface of the first steel box girder segment 11. In this embodiment, the second vertical support member 41 is fixed to the top surface of the first steel box girder segment 11 by welding. The second vertical support member 41 is made of I-beam. A horizontal support member 42 is fixed to the top of the second vertical support member 41 by welding. The horizontal support member 42 is perpendicular to a side wing plate of the second vertical support member 41 and extends toward the second steel box girder segment 12.
[0034] like Figure 3 As shown, a thrust device 2 for adjusting the height difference between the top surfaces of the first steel box girder segment 11 and the second steel box girder segment 12 is vertically arranged on the horizontal support member 42. The thrust device 2 can generate a vertical downward force, so that the second steel box girder segment 12 which is higher than the top surface of the first steel box girder segment 11 moves downward, and the height difference between the two is adjusted. In order to avoid displacement during the adjustment process, two limit plates 5 for limiting the lateral displacement of the thrust device 2 are welded on the top surface of the second steel box girder segment 12, which can ensure that the top plate of the thrust device 2 is located between the two limit plates 5.
[0035] like Figure 2 As shown, a thrust device 2 for adjusting the gap between the first steel box girder segment 11 and the second steel box girder segment 12 is horizontally arranged between the first vertical support member 32 and the second vertical support member 41. The thrust device 2 can generate a horizontal force to adjust the gap between the first steel box girder segment 11 and the second steel box girder segment 12.
[0036] In this embodiment, a jack is used as the thrust device 2. When adjusting the gap between the steel box girder segments, the bottom of the jack supports the first vertical support member 32, and the top plate of the jack supports the second vertical support member 41, and the gap between the first steel box girder segment 11 and the second steel box girder segment 12 is adjusted by telescoping the top plate of the jack. When adjusting the height difference misalignment of the steel box girder segments, the bottom of the jack supports the horizontal support member 42, and the top plate is located between the two limit plates 5 to support the second steel box girder segment 12, so as to adjust the misalignment between the first steel box girder segment 11 and the second steel box girder segment 12.
[0037] In this embodiment, the limiting plate 5, the first vertical support member 32 and the horizontal support member 42 can all be made of steel plates.
[0038] The specific method of using the bidirectional calibration device provided in this embodiment is as follows:
[0039] S1: Use a crane to hoist the first steel box girder segment 11 and the second steel box girder segment 12 to be installed onto the designated bracket, and roughly position the first steel box girder segment 11 and the second steel box girder segment 12. Use a total station to measure the gap and misalignment between the first steel box girder segment 11 and the second steel box girder segment 12.
[0040] S2: The vertical adjustment structure 4 is welded to the first steel box girder segment 11. One end of the adjustment stopper 31 is welded to the second steel box girder segment 12, and the opening 33 on the adjustment stopper 31 passes through the vertical adjustment structure 4. The adjustment stopper 31 as a whole spans the gap between the first steel box girder segment 11 and the second steel box girder segment 12. The stopper plate 5 is welded to the second steel box girder segment 12 below the opening 33.
[0041] S3: Place the jack horizontally between the first vertical support member 32 and the second vertical support member 41, and limit the position by adjusting the flange of the limit member 31. Start the jack to adjust the gap between the first steel box girder segment 11 and the second steel box girder segment 12. During the adjustment process, the jack pushes the two steel box girder segments closer to each other until they meet the requirements.
[0042] S4: Remove the jack between the first vertical support member 32 and the second vertical support member 41, and place the jack vertically between the horizontal support member 42 and the top surface of the second steel box girder segment 12. The top plate of the jack is located between the limit plates 5. Start the jack to apply a downward thrust to the second steel box girder segment 12, and at the same time, the horizontal support member 42 lifts the first steel box girder segment 11 upward. When the top surfaces of the first steel box girder segment 11 and the second steel box girder segment 12 are flush, stop the jack.
[0043] S5: Use a code plate across the joint to weld and fix the first steel box girder segment 11 and the second steel box girder segment 12, remove the jack, the horizontal adjustment structure 3, the vertical adjustment structure 4 and the limit plate 5, and complete the assembly adjustment.
[0044] The above-described embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
