AI Technical Summary
Existing technologies for arranging electrical distribution boxes on steel trestle bridges can increase costs or affect construction progress. Furthermore, existing arrangements are not flexible enough to adapt to the needs of different heights.
The system employs a retractable diagonal support structure and an I-beam platform, combined with a bolted assembly design to form a stable load-bearing platform that can adapt to different height requirements. The diagonal supports connect the I-beam platform to the steel trestle bridge, achieving both stability and flexibility for the platform.
This achieves stability and economy for the distribution box platform at different heights, improves construction efficiency, reduces construction costs, and does not affect the construction of underwater pile foundations and substructures.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction, and in particular to a prefabricated floating power distribution box support platform that can adapt to different heights. Background Technology
[0002] There are two main traditional methods for placing electrical distribution boxes on steel trestle bridges. The first method involves reserving space for the distribution boxes during the steel trestle bridge design phase and optimizing the layout. This approach increases the area of the steel trestle bridge and platform, raising costs. Furthermore, the layout optimization is limited, and the temporary power supply arrangement is complex, impacting the construction of the underwater pile foundations and substructure. The second method involves setting up a separate distribution box platform on one side of the steel trestle bridge. The substructure uses a single independent steel pipe pile, while the superstructure uses I-beams and Bailey bridges to construct the platform. The bridge deck uses checkered steel plates, and standard protection is installed around the perimeter. The platform is adjacent to the steel trestle bridge. This method requires separate platform design and construction, significantly increasing construction costs, but it does not affect the construction of the underwater pile foundations and substructure compared to the first method. Utility Model Content

[0005] In a preferred embodiment, the upper and lower horizontal sections of the I-beam are both rectangular, and the long sides of the horizontal sections of the multiple I-beams are connected to each other in pairs.
[0006] In a preferred embodiment, the diagonal support is divided into an upper support rod and a lower support rod. The upper support rod is inserted into the lower support rod.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example 1:
[0021] See the examples. Figures 1 to 3As shown, this utility model provides a prefabricated floating power distribution box support platform that can adapt to different heights, including a steel trestle bridge. Three support devices 1 are provided on the outermost side of the steel trestle bridge, and an upper platform 2 is provided above the support devices 1.
[0022] The I-beam platform 3 is located on the outside of the upper platform 2. The I-beam platform 3 includes multiple I-beams. The upper and lower horizontal parts of the I-beams are rectangular. The long sides of the horizontal parts of the multiple I-beams are connected to each other in pairs. A connecting plate 10 is provided on the side of the I-beam platform 3 that connects to the upper platform 2. Bolt holes are opened on the connecting plate 10. High-strength bolts pass through the bolt holes to fix the connecting plate 10 to the upper platform 2.
[0023] A patterned steel plate 4 is welded on top of the I-beam platform 3. Multiple diagonal supports are installed below the I-beam platform 3. The diagonal supports are divided into upper support rods 6 and lower support rods 7. The upper support rod 6 is inserted into the lower support rod 7. The upper end of the upper support rod 6 is rotatably connected to the I-beam platform 3. The lower end of the upper support rod 6 is provided with a retractable connecting buckle 8. The lower end of the lower support rod 7 is rotatably connected to the lower end of the support device 1 by bolts. Multiple sets of pin holes 9 are opened from the upper end to the middle of the lower support rod 7. Two pin holes are set in each set of pin holes 9. The connecting buckle 8 is engaged with the pin holes 9.
[0024] Guardrail 5 is set above the patterned steel plate 4. Guardrail 5 is set on the three outer edges of the patterned steel plate 4. Guardrail 5 is not set on the side of the patterned steel plate 4 near the connection part. Guardrail 5 is a telescopic structure and is fixedly connected to the patterned steel plate 4.
[0025] Example 2:
[0026] Construction steps of this utility model:
[0027] Step 1: Arrange multiple I-beams horizontally and weld them together along their long sides to form an overall frame. Then, weld a patterned steel plate 4 above the I-beam platform 3, ensuring that the steel plate is flat and tightly fitted to the I-beams. Install a connecting plate 10 on the side of the I-beam platform 3 closest to the upper platform 2 and fix the connecting plate 10 to the upper platform 2 with high-strength bolts.
[0028] Step 2: Connect the lower support rod 7 to the lower end of the support device 1 by bolts. Insert the upper support rod 6 into the lower support rod 7. Adjust the extension length of the upper support rod 6 so that the connecting buckle 8 is aligned with the pin hole 9 on the lower support rod 7. Select the corresponding pin hole 9 according to the required height, snap the connecting buckle 8 into the pin hole 9 and lock it to ensure that the diagonal support is stable. Check the tilt angle and connection strength of all diagonal supports.
[0029] Step 3: Install retractable guardrails 5 at the three outer edges of the patterned steel plate 4, adjust the height of the guardrails 5 to the design requirements, and lock the telescopic structure to ensure the protective function. Guardrails 5 do not need to be installed on the side close to the steel trestle bridge to preserve passage space.
