[0023] Refer to Figures 1 - 3 , a temporary construction support device for highway engineering, including a main protective fence 1. A slide rail 2 is provided on the side of the main protective fence 1. A secondary protective fence 3 is slidably connected to the inner wall of the slide rail 2. A jack 4 is provided at the top of the secondary protective fence 3. A circular groove 15 is provided at the top of the main protective fence 1. The top of the jack 4 corresponds to the circular groove 15. A bolt 5 is provided on the inner wall of the circular groove 15.

[0024] In the present utility model, when it is necessary to construct a large-area highway construction site, first, the staff needs to hold a tool and rotate the bolt 5 counterclockwise so that the bolt 5 is disengaged from the jack 4 in the secondary protective fence 3. Then, the staff can pull the secondary protective fence 3 to expand it to both sides. When the secondary protective fence 3 moves to the required position, the staff can again use the tool to rotate the bolt 5 clockwise so that the bolt 5 is inserted into the jack 4 in the secondary protective fence 3 to form positioning and locking, so as to support highway construction sites of different areas according to actual situations, thereby effectively improving the utilization rate of the construction support.

[0025] Refer to Figure 2, a T-shaped groove 6 is opened at the top of the main guardrail 1, the surface of the T-shaped groove 6 is communicated with the circular groove 15, a T-shaped block 7 is clamped on the inner wall of the T-shaped groove 6, and a threaded cylinder 8 is movably connected to the inner wall of the circular groove 15. The surface of the threaded cylinder 8 is fixedly connected to the T-shaped block 7, and a bolt 5 is movably connected to the inner wall of the threaded cylinder 8 through a thread.

[0026] In the present utility model, when the construction support device is used for a long time, the threaded cylinder 8 will be thread-slid. At this time, the staff can clamp the threaded cylinder 8 with a hand-held vise, and then pull the threaded cylinder 8 out of the circular groove 15 with an upward force. At the same time, the threaded cylinder 8 drives the T-shaped block 7 to be pulled out of the T-shaped groove 6, so as to facilitate the staff to replace the thread-slid threaded cylinder 8 and avoid increasing the economic cost due to overall replacement.

[0027] The vise in this solution is an existing technology, so it will not be introduced in detail here.

[0028] Refer to Figure 2 , first cross grooves 9 and second cross grooves 10 are respectively opened at the top of the bolt 5, and the second cross grooves 10 are located inside the first cross grooves 9.

[0030] Refer to Figure 2 , a threaded cover 11 is fixedly connected to the top of the main guardrail 1, and a protective cover 12 is threadedly connected to the surface of the threaded cover 11.

[0031] In the present utility model, when the bolt 5 is inserted into the jack 4 in the secondary guardrail 3, the staff can rotate the protective cover 12 to connect with the threaded cover 11, so as to protect the bolt 5 and the threaded cylinder 8 and prevent water molecules in the air from rusting and locking with the bolt 5 and the threaded cylinder 8, which is not conducive to subsequent adjustment of the lengths of the main guardrail 1 and the secondary guardrail 3.

[0032] Refer to Figure 2 , a pull handle 13 is rotatably connected to the surface of the protective cover 12, and the shape of the pull handle 13 can be set as an arc or a rectangle.

[0033] In the present utility model, through the arrangement of the pull handle 13, the contact area of the staff's hand can be increased, so as to facilitate the staff to better drive the protective cover 12 to rotate.

[0034] Refer to Figure 3 , mounting blocks 14 are fixedly connected to the bottoms of the main guardrail 1 and the secondary guardrail 3, and mounting holes are provided at the tops of the mounting blocks 14.

[0035] In the present utility model, through the provision of the mounting block 14, it is convenient for the staff to fix the main protective fence 1 and the secondary protective fence 3 by screws, thereby effectively increasing the stability of the main protective fence 1 and the secondary protective fence 3.

[0036] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
