Description

Technical Field

[0001] This utility model relates to the technical field of highway steel bridges, and specifically to an intelligent prefabricated highway steel bridge. Background Technology

[0002] Highway steel bridges are highway bridges constructed primarily of steel. They possess advantages such as high strength, high rigidity, large span capacity, suitability for industrial manufacturing, ease of transportation, good toughness and ductility, superior seismic performance, ease of repair and replacement, and environmental friendliness. Highway steel bridges consist of piers, I-beams, and precast bridge decks. When constructing small highway sightseeing bridges, the piers and precast pipe columns buried underground are first fixed. Then, the I-beams and piers are bolted together. Next, the precast bridge decks are bolted together with the steel beams, thus completing the assembly process of the highway steel bridge. Finally, the pouring of concrete completes the bridge construction.

[0003] In the use of existing highway steel bridges, the precast bridge panels need to be bolted to the steel beams. Therefore, it is necessary to first align the reserved holes on the precast bridge panels and the steel beams, and then insert and tighten the bolts. Since multiple precast bridge panels need to be installed on the steel beams, collisions may occur between the precast bridge panels during installation and tightening, causing misalignment between the reserved holes. As a result, when installing the next precast bridge panel, it is often necessary to remove the reserved holes on the previous precast bridge panel and the steel beam to re-align them, which increases the fixing time of the precast bridge panels.

[0004] On the other hand, after long-term use, existing precast bridge decks may experience bending under stress in some areas due to excessive load. It is necessary to collect data on these areas prone to bending to provide a basis for future additions and maintenance. Existing highway steel bridges cannot meet the current needs.

[0005] Therefore, there is an urgent need to provide an intelligent prefabricated highway steel bridge to address the defects and shortcomings of the existing technologies. Utility Model Content

[0030] [First Embodiment]

[0031] Reference Figure 1-5 The image shown is an intelligent prefabricated highway steel bridge provided in the first embodiment of this utility model, as follows: Figure 1As shown, the bridge includes a pier 1, an I-beam 4 on top of the pier 1, and a precast bridge deck 5 on top of the I-beam 4. The improvement of this embodiment compared to the prior art is that an intelligent detection component 3 is installed between the I-beams 4. This intelligent detection component allows for repeated detection of the bottom of the precast bridge deck. The detection data is uploaded to the control console via a network module for analysis, thereby achieving intelligent collection of the precast bridge deck's bending data under stress, providing a basis for future additions and maintenance of this local area. Furthermore, a pre-fixing component 2 is installed on one side of the I-beam 4. This pre-fixing component, through a fixing box, achieves the insertion and installation limitation effect of the internal positioning rod. Hexagonal nuts are pre-placed in the mounting groove to facilitate screwing in the bolts, thus fixing the precast bridge deck to the top of the I-beam. During this process, the slider is located inside the groove to achieve overlapping positioning of the precast bridge deck and the pre-drilled holes on the I-beam, minimizing the increased fixing time of the precast bridge deck due to misalignment between the pre-drilled holes.

[0032] like Figure 3-4 As shown, the pre-fixing component 2 in this embodiment includes a fixing box 21 disposed on one side of the I-shaped steel beam 4. A positioning rod 22 is slidably connected to the inner wall of the fixing box 21. A first elastic element 24 is disposed between the bottom of the positioning rod 22 and the inner cavity of the fixing box 21. The top of the fixing box 21 has an installation groove 23 for placing a hexagonal nut. The positioning rod 22 is threadedly engaged with the hexagonal nut. At the same time, a sliding groove 25 is provided on one side of the I-shaped steel beam 4. A slider 26 is fixed on one side of the fixing box 21. The slider 26 is located inside the sliding groove 25 and slides vertically with it. The fixing box achieves the insertion and installation limiting effect of the positioning rod inside. A hexagonal nut is placed in the mounting slot to facilitate the screwing in of the bolt, thereby fixing the precast bridge panel to the top of the I-beam. During this process, the slider is located inside the groove to achieve the alignment and positioning of the precast bridge panel and the precast steel beam with the reserved holes, minimizing the defects caused by the misalignment between the reserved holes and the increased fixing time of the precast bridge panel. By sliding the slider in the groove, the precast holes on the precast bridge panel and the I-beam can be aligned and positioned. After installation, the fixing box can be removed by sliding the slider in the groove, and the fixing box can be used in the next installation and fixing process between the precast bridge panel and the I-beam.

[0033] like Figure 4As shown, a pin 27 is slidably inserted into one side of the slider 26. The pin 27 can be inserted into the interior of the I-shaped steel beam 4 and engage with it from the front and back. The pin 27 is inserted into the interior of the I-shaped steel beam 4 to fix the fixed box 21. Correspondingly, a third elastic element 28 is fixedly connected to one side of the pin 27. The other end of the third elastic element 28 is fixedly connected to the slider 26. The third elastic element 28 is used to reset the fixed box 21 after it has been released from its fixed position. As a further preferred embodiment, a pull rope 29 is fixedly connected to one side of the pin 27. The other end of the pull rope 29 passes through the gap between the slider 26 and the fixed box 21. By pulling the pull rope, the pin can be moved, thereby further improving the convenience of operation.

[0034] like Figure 2 and Figure 5 As shown, the intelligent detection component 3 in this embodiment includes a slide rail 31 on one side of the I-shaped steel beam 4, an installation rod 32 between two adjacent I-shaped steel beams 4, wheels 33 at both ends of the installation rod 32, the wheels 33 being driven by an external motor, the wheels 33 being located inside the slide rail 31 and rolling in cooperation with it, a measuring rod 36 passing through the inside of the installation rod 32, a detection cylinder 35 being rotatably connected to the top of the measuring rod 36, a U-shaped rod 34 being fixedly connected to the bottom of the measuring rod 36, and a scale being provided on the outer edge of the measuring rod 36. A camera 37 is mounted on the top of the mounting rod 32. The drive motor drives the wheel 33 to rotate, causing the mounting rod 32 to move within the slide rail 31. This allows the detection cylinder 35 at the top of the U-shaped rod to move at the bottom of the precast bridge panel. The bending change at the bottom of the precast bridge panel is detected by the detection cylinder, causing the measuring rod to change. The camera captures the changes in the scale on the measuring rod. The bottom of the precast bridge panel can be detected multiple times. The detected data is uploaded to the control console for analysis via a network module, thereby realizing intelligent collection of data on the bending of the precast bridge panel under stress.

[0035] As a further preferred embodiment, a second elastic element 38 is provided between the top of the U-shaped rod 34 and the bottom of the mounting rod 32. The second elastic element 38 can help to reset the measuring rod 36 after the test is completed.

[0036] The specific working process of this embodiment is as follows:

[0037] When constructing a small highway sightseeing bridge, the first step is to fix the pier 1 and the precast pipe column buried underground. Then, the I-beam 4 and the pier 1 are bolted together. Next, the precast bridge deck 5 and the I-beam 4 are bolted together, thus completing the assembly process of the highway steel bridge. Finally, the pouring operation is carried out to complete the construction of the bridge.

[0038] When fixing the precast bridge deck 5 to the I-beam 4, drag the precast bridge deck 5 and place it on top of the I-beam 4. Insert the positioning rod 22 sequentially through the mounting holes on the I-beam 4 and the precast bridge deck 5 until it enters the fixing box 21. Similarly, positioning rods 22 at other positions can be inserted into the corresponding mounting holes, thereby achieving pre-fixation between the precast bridge deck 5 and the I-beam 4 as much as possible. Hexagonal nuts are pre-placed in the mounting groove 23 to facilitate the screwing of the positioning rods 22 into the hexagonal nuts. As the positioning rod 22 is tightened and pressed down, the first elastic element 24 is compressed and contracted to fix the precast bridge panel 5 to the I-beam 4. Then, the pull rope 29 is pulled so that the pin 27 moves to be fully retracted into the slider 26. Then, the fixing box 21 is dragged down and slides in the groove 25 through the slider 26 to fix the fixing box 21. The fixing box 21 can then be taken out and applied to the next precast bridge panel 5 position to achieve its installation and fixation. By setting the third elastic element 28, the pin 27 can be reset.

[0039] When it is necessary to collect data on the bending of the precast bridge deck 5 under intelligent detection, the drive motor drives the wheel 33 to rotate, causing the mounting rod 32 to move within the slide rail 31. This causes the detection cylinder 35 on the U-shaped rod 34 to move at the bottom of the precast bridge deck 5. The bending change at the bottom of the precast bridge deck 5 causes the measuring rod 36 to change through the detection cylinder 35. The camera 37 captures the scale changes on the measuring rod 36 in real time. The bottom of the precast bridge deck 5 can be detected multiple times. The detected data is uploaded to the control console for analysis through the network module, thereby intelligently collecting the bending data of the precast bridge deck 5 under intelligent detection. The measuring rod 36 can be reset after the detection is completed by the set second elastic element 38.
