Description

Technical Field

[0001] This utility model belongs to the field of highway construction technology, and in particular relates to a highway construction retaining structure. Background Technology

[0002] Currently, most highway construction enclosures use corrugated steel sheet fencing. After the completion of highway construction in a certain area, users usually dismantle the corrugated steel sheet fencing and then transport it by truck. The triangular support frame on the back of the corrugated steel sheet fencing is relatively troublesome to assemble and disassemble. Therefore, there is a need for a highway construction enclosure that can support the corrugated steel sheet fencing through a support structure, avoiding the need for users to assemble triangular support frames to support the corrugated steel sheet fencing, thus improving the efficiency of corrugated steel sheet fencing turnover.

[0021] Figure 1-4 This invention illustrates a highway construction retaining structure according to an embodiment of the present invention. It includes a protective plate 1. Two symmetrical support frames 2 are rotatably connected to the front of the protective plate 1. The support frames 2 are channel steel, and the connecting rods 3 are hollow round tubes. Telescopic rods 5 slide within the inner cavity of a tightening plate 7. A connecting rod 3 is fixedly connected between the two support frames 2. A rotating tube 4 is rotatably connected to the back of the support frames 2. The inner cavity of the rotating tube 4 is slidably connected to the telescopic rods 5. The top of the telescopic rods 5 is rotatably connected to the front of the protective plate 1. A threaded fixing tube 6 is fixedly connected to the top of the rotating tube 4, and four pairs of... The tightening plate 7 and the threaded fixing tube 6 are threadedly connected to a threaded sleeve 8. The surface of the threaded sleeve 8 is provided with anti-slip texture. The fixing frame 11 is made of I-shaped steel and is adapted to the connecting rod 3. The inner cavity of the threaded sleeve 8 is fixedly connected to a shrink ring 9, which is adapted to the tightening plate 7. The top of the connecting rod 3 is provided with a limit hole 10. The front of the protective plate 1 is fixedly connected to the fixing frame 11. The connecting rod 3 is located in the inner cavity of the fixing frame 11.

[0022] Working principle: When using this utility model, the user pulls the fixing bolt 12 out of the inner cavity of the limiting hole 10, rotates the threaded sleeve 8, causing the threaded sleeve 8 to move upward, so that the shrink ring 9 disengages from the surface of the tightening piece 7, moves the support frame 2, so that the included angle between the support frame 2 and the protective plate 1 is 90 degrees, rotates the threaded sleeve 8, so that the threaded sleeve 8 and the threaded fixing tube 6 move threadedly, so that the threaded sleeve 8 drives the shrink ring 9 to tighten the tightening piece 7, so that the tightening piece 7 is clamped on the surface of the telescopic rod 5, thereby limiting the telescopic rod 5. At this time, the rotating tube 4 of the support frame 2 and the telescopic rod 5 will support the protective plate 1, avoiding the need for the user to assemble a triangular support frame to support the color steel plate fence, thus improving the turnover efficiency of the color steel plate fence.

[0023] In summary: This highway construction enclosure, by rotating the threaded sleeve 8, causes the shrink ring 9 to disengage from the surface of the tightening plate 7. Then, the fixing bolt 12 is pulled out of the inner cavity of the limiting hole 10, and the support frame 2 is rotated to extend the telescopic rod 5. When the support frame 2 reaches the appropriate position, rotating the threaded sleeve 8 causes the shrink ring 9 to be fitted onto the surface of the tightening plate 7. This achieves the goal of supporting the color steel plate enclosure through the support structure, avoiding the need for users to assemble triangular support frames to support the color steel plate enclosure, and improving the turnover efficiency of the color steel plate enclosure.
