Description

Technical Field

[0001] This application relates to the field of bridge construction operation platforms, and in particular to a prefabricated rapid construction operation platform suitable for bridges across water. Background Technology

[0002] Bridge construction operation platforms are temporary platform structures used for construction personnel to work, material storage, and mechanical equipment placement during bridge construction. They mainly use Bailey beams (prefabricated steel trusses) as the main load-bearing components and concrete or steel columns for foundation support. The platform panels are mostly paved with steel plates or bamboo plywood. With their modular design, high load-bearing capacity, and convenient assembly and disassembly characteristics, they are widely used in high-altitude operations, material transportation, and equipment placement in bridge construction.

[0003] Currently, most bridge construction projects involving water use bridge construction platforms. When assembling Bailey bridges, bolts and crossbars are mostly used to fix the Bailey panels. This process involves a large number of bolts and is quite complicated. Therefore, there is a need for a prefabricated rapid construction platform for water-related bridges that can assemble Bailey bridges through a fixed structure, avoiding the need for users to use a large number of bolts to fix the Bailey panels and improving the efficiency of Bailey bridge assembly. Utility Model Content

[0004] To address the existing technical problems, this application provides a prefabricated rapid construction platform suitable for bridges crossing water.

[0005] This application provides a prefabricated rapid construction platform suitable for water-crossing bridges, employing the following technical solution: A prefabricated rapid construction platform suitable for water-crossing bridges includes two symmetrical support columns. Multiple pairs of identical steel frames are installed on the top of the support columns. Two symmetrical connecting slots are opened on the left side of each steel frame. Two symmetrical connecting blocks are fixedly connected to the right side of each steel frame. The connecting slots are adapted to the connecting blocks. Two symmetrical bolts are threaded through the front of each steel frame, penetrating the steel frame and connecting blocks and connected with hexagonal nuts. Four symmetrical fixing rods are fixedly connected to the right side of each steel frame. Four symmetrical fixing frames are fixedly connected to the left side of each fixing frame. A positioning sleeve is threaded through the left side of each fixing frame, adapting to the fixing rod. Two symmetrical connecting steel beams are provided on the right side of each steel frame. The fixing rods are threaded through and connected to the crossbars, adapting to the crossbars.

[0006] By adopting the above technical solution, two symmetrical steel frames are placed side by side, and two symmetrical connecting crossbars are placed on the right side of the two symmetrical steel frames, so that the fixing rod passes through the connecting crossbar. Then, two more steel frames are placed on the right side of the connecting crossbar, and the connecting block is pushed into the inner cavity of the connecting groove, so that the bolt passes through the steel frame and the connecting block and is threaded with a hexagonal nut. This completes the assembly of the support column, avoiding the need for users to use a lot of bolts to fix the Bailey panels and improving the efficiency of Bailey beam assembly.

[0007] Preferably, a connecting steel beam is fixedly connected between the two supporting columns, and the connecting steel beam is fixedly connected to the two supporting columns.

[0008] Preferably, the top of the connecting steel beam is provided with two symmetrical limiting frames, which are located in the inner cavity of the steel frame.

[0009] Preferably, the inner cavity of the limiting frame is provided with a pressure plate, and two symmetrical limiting rods are fixedly connected to the top of the pressure plate.

[0010] Preferably, a threaded rod is provided through the top of the limiting frame, the threaded rod passes through the limiting frame and is rotatably connected to the pressure plate, and the threaded rod is threadedly connected to the limiting frame.

[0011] Preferably, the limiting frame has adjustment holes on both the front and back sides, and a threaded rod is provided through the inner cavity of the adjustment hole. One end of the threaded rod passes through the inner cavity of the limiting frame and fits against the steel frame.

[0012] Preferably, the surface of the threaded rod two is threaded with a fastening nut, which fits against the front and back of the inner cavity of the limiting frame.

[0013] By employing the above technical solution, through the coordinated use of the limiting frame, pressure plate, limiting rod, threaded rod one, adjusting hole, threaded rod two, and fastening nut, when the steel frame is at the top of the supporting column, the limiting frame passes through the steel frame, allowing it to be mounted at the bottom of the steel frame. The limiting frame is then fixedly connected to the connecting steel beam using bolts. Rotating threaded rod one causes it to move threadedly with the limiting frame. The limiting rod's movement causes the pressure plate to move downwards, limiting the steel frame. Threaded rod two then passes through the adjusting hole and moves threadedly with the fastening nut. Continuing to rotate the fastening nut causes threaded rod two to pass through the adjusting hole and the fastening nut, bringing it into contact with the steel frame. At this point, the fastening nut will be in contact with the inner wall of the limiting frame, limiting threaded rod two on both the front and back of the steel frame, preventing displacement of the steel frame at the top of the connecting steel beam and improving the stability of the steel frame.

[0014] Preferably, the front and back of the limiting frame are fixedly connected to two symmetrical reinforcing plates, the reinforcing plates are triangular, and the reinforcing frame is fixedly connected between the two supporting columns.

[0015] By adopting the above technical solution, and by setting up a reinforcing frame between the two supporting columns, when the steel frame is set on top of the supporting columns, the reinforcing frame will support the two symmetrical supporting columns, preventing the supporting columns from tilting under pressure and improving the stability of the supporting columns.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This utility model involves placing two symmetrical steel frames side by side, placing two symmetrical connecting crossbars on the right side of the two symmetrical steel frames, allowing the fixing rod to pass through the connecting crossbars, and then placing two more steel frames on the right side of the connecting crossbars. The connecting block is then pushed into the inner cavity of the connecting groove, allowing the bolt to pass through the steel frame and the connecting block and be threaded to the nut, thus completing the assembly of the support column. This avoids the need for users to use a large number of bolts to fix the Bailey panels, improving the efficiency of Bailey beam assembly.

[0018] 2. This utility model utilizes a combination of a limiting frame, a pressure plate, a limiting rod, a threaded rod one, an adjusting hole, a threaded rod two, and a fastening nut. When the steel frame is at the top of the supporting column, the limiting frame passes through the steel frame, placing it at the bottom. Bolts secure the limiting frame to the connecting steel beam. Rotating the threaded rod one causes it to thread with the limiting frame. The limiting rod's movement causes the pressure plate to move downwards, limiting the steel frame. The threaded rod two passes through the adjusting hole and threads with the fastening nut. Continuing to rotate the fastening nut causes the threaded rod two to pass through the adjusting hole and the fastening nut, coming into contact with the steel frame. At this point, the fastening nut will be in contact with the inner wall of the limiting frame, limiting the threaded rod two on both the front and back of the steel frame, preventing displacement of the steel frame at the top of the connecting steel beam and improving the stability of the steel frame.

[0019] 3. By setting up a reinforcing frame between the two supporting columns, when the steel frame is set on top of the supporting columns, the reinforcing frame will support the two symmetrical supporting columns, preventing the supporting columns from tilting under pressure and improving the stability of the supporting columns.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] Example 1:

[0027] Combination Figures 1-4This application discloses a prefabricated rapid construction platform suitable for water-related bridges, including two symmetrical support columns 1. A connecting steel beam 9 is fixedly connected between the two support columns 1. The connecting steel beam 9 is fixedly connected to the two support columns 1. Two symmetrical limiting frames 10 are provided on the top of the connecting steel beam 9. The limiting frames 10 are located in the inner cavity of the steel frame 2. A pressure plate 11 is provided in the inner cavity of the limiting frame 10. Two symmetrical limiting rods 12 are fixedly connected to the top of the pressure plate 11. A threaded rod 13 is provided through the top of the limiting frame 10. The threaded rod 13 passes through the limiting frame 10 and is rotatably connected to the pressure plate 11. The threaded rod 13 is threadedly connected to the limiting frame 10. The front and back of the positioning frame 10 are provided with adjustment holes 14. A threaded rod 15 is inserted through the inner cavity of the adjustment hole 14. One end of the threaded rod 15 passes through the inner cavity of the positioning frame 10 and fits against the steel frame 2. A fastening nut 16 is threaded onto the surface of the threaded rod 15. The fastening nut 16 fits against the front and back of the inner cavity of the positioning frame 10. Through the coordinated use of the positioning frame 10, pressure plate 11, positioning rod 12, threaded rod 13, adjustment hole 14, threaded rod 15, and fastening nut 16, when the steel frame 2 is located at the top of the supporting column 1, the positioning frame 10 passes through the steel frame 2, so that the positioning frame 10 is mounted at the bottom of the steel frame 2. The positioning frame 10 is secured by bolts. 0 is fixedly connected to the connecting steel beam 9. Rotating the threaded rod 13 causes the threaded rod 13 to move threadedly with the limiting frame 10. Through the limiting rod 12, the pressure plate 11 moves downward to limit the steel frame 2. The threaded rod 15 passes through the adjusting hole 14 and moves threadedly with the fastening nut 16. Continuing to rotate the fastening nut 16 causes the threaded rod 15 to pass through the adjusting hole 14 and the fastening nut 16 and fit against the steel frame 2. At this time, the fastening nut 16 will fit against the inner wall of the limiting frame 10, so that the threaded rod 15 limits the front and back of the steel frame 2, preventing the steel frame 2 from shifting at the top of the connecting steel beam 9, thus improving the stability of the steel frame 2. The top of the supporting column 1 is equipped with Multiple identical steel frames 2 are provided. Two symmetrical connecting slots 3 are opened on the left side of the steel frame 2. Two symmetrical connecting blocks 4 are fixedly connected to the right side of the steel frame 2. The connecting slots 3 and connecting blocks 4 are adapted to each other. Two symmetrical bolts are provided through the front of the steel frame 2. The bolts pass through the steel frame 2 and the connecting blocks 4 and are threaded with hexagonal nuts. Four symmetrical fixing rods 5 are fixedly connected to the right side of the steel frame 2. Four symmetrical fixing brackets 6 are fixedly connected to the left side of the steel frame 2. A positioning sleeve 7 is provided through the left side of the fixing bracket 6. The positioning sleeve 7 is adapted to the fixing rod 5. Two symmetrical connecting steel beams 9 are provided on the right side of the steel frame 2. The fixing rods 5 pass through the connecting crossbars 8 and are adapted to the connecting crossbars 8.

[0028] Example 2:

[0029] Combination Figure 2 and Figure 4The front and back of the limiting frame 10 are fixedly connected to two symmetrical reinforcing plates 17. The reinforcing plates 17 are triangular. The reinforcing frame is fixedly connected between the two support columns 1. With the reinforcement frame between the two support columns 1, when the steel frame 2 is set on the top of the support columns 1, the reinforcement frame will support the two symmetrical support columns 1, prevent the support columns 1 from tilting under pressure, and improve the stability of the support columns 1.

[0030] Working Principle: In use, the user places multiple steel frames 2 side-by-side, positions two symmetrical connecting crossbars 8 to the right of the two symmetrical steel frames 2, and allows the fixing rod 5 to pass through the connecting crossbars 8. This pushes the two symmetrical steel frames 2 towards the other two steel frames 2, causing the connecting block 4 to enter the inner cavity of the connecting groove 3. At this time, the positioning sleeve 7 will be fitted onto the surface of the fixing frame 6 and fit against the connecting crossbar 8, allowing the bolt to pass through the steel frame 2 and the connecting block 4 and be threaded with a hexagonal nut, completing the assembly of the four symmetrical steel frames 2. This avoids the need for the user to use a large number of bolts to fix the Bailey bridge panels, improving the efficiency of Bailey beam assembly. When the steel frame 2 is assembled, the limiting frame 10 passes through the steel frame 2, limiting the movement of the steel frame. The frame 10 is mounted at the bottom of the steel frame 2. The limiting frame 10 is fixedly connected to the connecting steel beam 9 by bolts. Rotating the threaded rod 13 causes the threaded rod 13 to move threadedly with the limiting frame 10. Through the limiting rod 12, the pressure plate 11 moves downward to limit the steel frame 2. The threaded rod 15 passes through the adjustment hole 14 and moves threadedly with the fastening nut 16. Continuing to rotate the fastening nut 16 causes the threaded rod 15 to pass through the adjustment hole 14 and the fastening nut 16 and fit against the steel frame 2. At this time, the fastening nut 16 will fit against the inner wall of the limiting frame 10, so that the threaded rod 15 limits both the front and back of the steel frame 2, preventing the steel frame 2 from shifting at the top of the connecting steel beam 9 and improving the stability of the steel frame 2.

[0031] In summary, this prefabricated rapid construction platform suitable for water-crossing bridges completes the assembly of the support column 1 by placing two symmetrical steel frames 2 side by side, placing two symmetrical connecting crossbars 8 on the right side of the two symmetrical steel frames 2, allowing the fixing rod 5 to pass through the connecting crossbar 8, and then placing two more steel frames 2 on the right side of the connecting crossbar 8. The connecting block 4 is then pushed into the inner cavity of the connecting groove 3, allowing the bolt to pass through the steel frame 2 and the connecting block 4 and be threaded with a hexagonal nut. This avoids the need for users to use a large number of bolts to fix the Bailey bridge panels, thus improving the efficiency of Bailey bridge assembly.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
