Description

Technical Field

[0002] In modern bridge and flume projects, the in-situ beam casting construction technology is widely used due to its strong adaptability and flexible construction. However, due to the complex mechanical deformation and structural stress problems involved in the in-situ construction process, how to scientifically and reasonably set the support camber has become one of the key technologies to ensure construction quality and structural safety.

[0003] As a commonly used in-situ box girder formwork system, the Bailey beam has been widely used in the construction of long-span bridges due to its high strength, high stiffness, and large spanning distance. However, the Bailey beam support method is affected by various factors during construction, including foundation settlement, elastic deformation of the support, inelastic deformation, concrete shrinkage, and creep, etc. These factors will all affect the elevation of the Bailey beam. Therefore, before construction, it is necessary to accurately measure the elastic deformation and inelastic deformation values of the Bailey beam through methods such as preloading, and calculate a reasonable camber based on this to ensure that the alignment of the Bailey beam meets the design requirements.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0037] The present invention will be described in detail below with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. For the convenience of narration, words such as "upper", "lower", "left", and "right" in the following text only indicate the same direction as the upper, lower, left, and right directions of the drawings themselves, and do not limit the structure.

[0038] As Figure 1 , Figure 2 shown, a Bailey beam flume machine provided in this embodiment is respectively installed between every two capping beams 7 and is used for pouring a flume between the two capping beams 7. The Bailey beam flume machine includes a Bailey beam 1, a formwork system 6 arranged above the Bailey beam 1, a support system 8 for supporting between the Bailey beam 1 and the formwork system 6, an adjustment system 2 installed at the upper end of the Bailey beam 1 for adjusting the camber of the formwork system 6, a drive system 4 for driving the adjustment system 2 to act to complete the camber adjustment, an adjustment block 5, and a hydraulic control system 3.

[0039] As Figure 2As shown, n groups of Bailey beams 1 are arranged in the width direction Y of the capping beam 7. In this embodiment, n = 8. A plurality of adjusting systems 2 are provided on the two middle groups of Bailey beams 1 and on the Bailey beams 1 at both ends in the width direction Y. The plurality of adjusting systems 2 are evenly spaced in the length direction of the Bailey beam 1. A plurality of supporting systems 8 are provided on the remaining four Bailey beams 1. The plurality of supporting systems 8 are provided in one-to-one correspondence with the plurality of adjusting systems 2.

[0040] As Figure 3 shown, the adjusting system 2 includes two relatively arranged first lower toothed blocks 21, a first upper toothed block 22 provided at the upper ends of the two first lower toothed blocks 21, and a first threaded steel bar 23 connected between the two first lower toothed blocks 21 and extending to the outside of the two first lower toothed blocks 21. A first abutting member 25 and a first nut 24 are sleeved on the first threaded steel bar 23 extending to the outside of the first lower toothed block 21. The plurality of adjusting systems 2 on the same Bailey beam 1 share one first threaded steel bar 23, that is, the first threaded steel bar 23 connects the plurality of adjusting systems 2 end to end in sequence.

[0041] The first nut 24 is threadedly connected to the first threaded steel bar 23 to abut the first abutting member 25 against the outer surface of the first lower toothed block 21. The driving system 4 is provided between the first abutting member 25 and the first nut 24 on one of the first lower toothed blocks 21. The driving system 4 is connected to the first threaded steel bar 23 in a tensioning manner. A first slope surface 211 is provided at the upper end of the first lower toothed block 21. The first slope surfaces 211 on the two relatively arranged first lower toothed blocks 21 form a V shape. A second slope surface 221 adapted to the two first slope surfaces 211 is provided at the lower end of the first upper toothed block 22. When the driving system 4 pulls the first threaded steel bar 23, the two first lower toothed blocks 21 move closer to each other. Thus, through the cooperation of the first slope surface 211 and the second slope surface 221, the first upper toothed block 22 is lifted.

[0042] The first lower toothed block 21 and the first upper toothed block 22 can be made of wooden squares or steel parts. In this embodiment, wooden squares are used. The slopes of the first slope surface 211 and the second slope surface 221 are 1:8.

[0043] A semi-circular groove is provided at the upper end of the first upper toothed block 22. The diameter of the groove is 100 mm and the central angle of the arc is 150 degrees. An adjusting block 5 is provided in the groove. The adjusting block 5 is cylindrical and is made of a wooden square or a customized steel section. One side surface thereof is an arc surface adapted to the groove, and the other side surface is a plane. When in use, lubricating oil is applied to the arc surface of the adjusting block 5, and it can rotate freely in the groove. When the aqueduct and the formwork system 6 have a certain longitudinal slope, the adjusting block 5 can rotate to adapt to this slope.

[0044] The drive system 4 includes a through jack 41 and a baffle 42 provided on one side surface of the through jack 41. The first nut 24 abuts against the baffle 42. The first threaded steel bar 23 passes through the through jack 41 and the baffle 42, and one end of the through jack 41 close to the first abutting member 25 forms a tensioning end. As Figure 1 shown, each through jack 41 is connected to the hydraulic control system 3. The first abutting member 25 is made of a channel steel. The working principle of the through jack 41 is as follows: When it is necessary to tension the first threaded steel bar 23, oil enters through the oil nozzle of the tensioning cylinder of the through jack 41, and oil returns through the oil nozzle of the jacking cylinder, thereby pulling one first lower tooth block 21 to approach and displace another first lower tooth block 21. Conversely, it moves away from and descends the first upper tooth block 22. The through jack 41 is 8t.

[0045] In this embodiment, a total of 8 adjustment systems 2 and drive systems 4 are provided on the same Bailey beam 1, and 4 groups with different elongation values are symmetrically arranged through the hydraulic control system 3.

[0046] As Figure 4 shown, the support system 8 includes two relatively arranged second lower tooth blocks 81, a second upper tooth block 82 provided at the upper ends of the two second lower tooth blocks 81, and a second threaded steel bar 83 connected between the two second lower tooth blocks 81 and extending outside the two second lower tooth blocks 81. Multiple second threaded steel bars 83 on the same Bailey beam 1 can be combined into one second threaded steel bar 83. A second abutting member 85 and a second nut 84 are sleeved on the second threaded steel bar 83 extending outside the second lower tooth block 81. The second nut 84 is threadedly connected to the second threaded steel bar 83 to abut the second abutting member 85 against the outer surface of the second lower tooth block 81.

[0047] The second lower tooth block 81 has the same structure as the first lower tooth block 21, and the second upper tooth block 82 has the same structure as the first upper tooth block 22. Similarly, a groove is provided at the upper end of the second upper tooth block 82, and an adjusting block 5 is arranged in the groove. The adjusting block 5 is cylindrical, with one side surface being an arc surface adapted to the groove and the other side surface being a plane. A third slope 811 is provided at the upper end of the second lower tooth block 81, and the third slopes 811 on the two relatively arranged second lower tooth blocks 81 form a V shape. A fourth slope 821 adapted to the two third slopes 811 is provided at the lower end of the second upper tooth block 82.

[0048] As Figure 1 shown, a hanging member 9 is provided on the capping beam 7, and cross beams 11 are provided at both the upper and lower ends of the Bailey beam 1. The cross beam 11 and the hanging member 9 are connected by bolts and other fasteners.

[0049] The present invention also provides a method for building the above-mentioned Bailey beam slot-making machine, including:

[0050] Step 1: Assemble the Bailey beam 1 according to the spacing between two capping beams 7, and install the Bailey beam 1 on the capping beam 7. The Bailey beam 1 needs to be kept horizontally set to improve the bearing capacity;
