Specific implementation manners
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-4 , a support mechanism for concrete pouring in highway engineering in this embodiment, including a support plate 1 for enclosing the concrete pouring. The support plate 1 is composed of a plurality of support formworks 2 spliced together, and a sealing connection mechanism 3 is arranged on the support formwork 2.
[0024] Specifically, the sealed connection mechanism 3 includes a mounting block 301. The mounting block 301 is fixedly installed on the left side of the supporting formwork 2. A limiting block 302 is fixedly installed on the right side of the supporting formwork 2. An installation groove 303 is formed on the side wall of the mounting block 301 away from the supporting formwork 2. A cavity 304 is formed inside the limiting block 302. Sealing airbags 305 are fixedly installed on both the upper and lower side walls of the limiting block 302. Air pipes 306 are connected to both the upper and lower side walls of the limiting block 302. An air inlet valve 307 is installed on the front side of the limiting block 302. An air outlet valve 308 is installed on the front side of the limiting block 302. A rotating shaft 309 is rotatably connected to the front side wall of the supporting formwork 2. A mounting plate 310 is fixedly installed on the outer part of the rotating shaft 309. A limiting threaded groove 311 is formed on the front side wall of the limiting block 302. By providing the sealed connection mechanism 3, when connecting multiple supporting formworks 2, it can prevent concrete from seeping out from the gap at the connection. By inserting the limiting hole 302 into the installation groove 303 of another supporting formwork 2, then rotating the mounting plate 310 to align the fixing bolt 4 with the limiting threaded groove 311, and then screwing the fixing bolt 4 into the limiting threaded groove 311. At this time, pump air into the air inlet valve 307, so that the gas enters the sealing airbag 305 through the cavity 304 and the air pipe 306, making the sealing airbag 305 inflated to block the gap between the limiting block 302 and the mounting block 301 to prevent concrete from flowing into the gap. During disassembly, it is necessary to first discharge the gas in the airbag 305 through the air outlet valve 308, and then unscrew the fixing bolt 4 to release the limit.
[0025] Specifically, both the air inlet valve 307 and the air outlet valve 308 are connected to the inside of the cavity 304. A fixing bolt 4 is provided on the mounting plate 310. A threaded hole adapted to the fixing bolt 4 is provided on the mounting plate 310. During installation, it is necessary to align the threaded hole with the limiting threaded groove 311, and then screw the fixing bolt 4 into the threaded hole and the limiting threaded groove 311 to complete the fixation.
[0026] Specifically, a first hinge seat 5 is fixedly installed at the bottom of the supporting formwork 2. A connecting rod 6 is hinged to the first hinge seat 5. The bottom of the connecting rod 6 is hinged to a second hinge seat 7. A fixing plate 8 is fixedly installed at the bottom of the second hinge seat 7. Four threaded rods 9 are threadedly connected to the fixing plate 8. A plug rod 10 is installed on one side of the threaded rod 9. By providing the hinge seat 5, it is convenient to adjust the angle of the supporting formwork 2. By rotating the threaded rod 9 and inserting the plug rod 10 into the soil, with the cooperation and support of the connecting rod 6, the supporting formwork 2 can be installed more stably.
[0027] In summary, for the support mechanism for concrete pouring in the highway project, by setting the sealed connection mechanism 3, it is possible to prevent concrete from leaking out through the gaps at the joints when connecting multiple support templates 2. By inserting the limiting hole 302 into the installation groove 303 of another support template 2, then rotating the installation plate 310 to align the fixing bolt 4 with the limiting thread groove 311, and then screwing the fixing bolt 4 into the limiting thread groove 311. At this time, pump air into the air inlet valve 307, so that the gas enters the sealed airbag 305 through the cavity 304 and the air pipe 306, causing the sealed airbag 305 to expand and block the gap between the limiting block 302 and the installation block 301 to prevent concrete from flowing into the gap, thus solving the problem that concrete easily leaks out through the gaps at the joints of the support templates.
