Description

Technical Field

[0001] This utility model relates to the technical field of template fixing devices, specifically a template fixing device for concrete ditch construction. Background Technology

[0002] As highway and railway construction extends to mountainous and hilly areas, the design of roadbed side ditches needs to adjust the slope angle according to the terrain. The construction quality directly affects the stability and service life of the roadbed. During the pouring of the side ditches, in order to ensure the geometric dimensions and positional accuracy of the side ditches, the formwork needs to be firmly fixed to prevent the formwork from shifting or deforming due to the lateral pressure of the concrete during the pouring process.

[0003] A Chinese patent with publication number CN217128459U discloses a positioning bracket for concrete formwork in a ditch. By operating a top motor, two inserts are brought closer together. Then, the concrete formwork body, bottom plate, and bottom blocks are moved until the two bottom plates are located on both sides of the outer top wall of the positioning box, and the two bottom blocks are inserted into the two recessed holes. Then, by operating the top motor, the two inserts are inserted into the two recessed slots, thus positioning the concrete formwork body, bottom plate, and bottom blocks. This makes the positioning process of the concrete formwork in a ditch simple and labor-saving, and helps to improve the efficiency of ditch construction.

[0004] In the aforementioned literature, the existing ditch formwork positioning brackets, due to their fixed support angles during use, cannot adapt to the construction requirements of different slope angles, resulting in a limited angle support range. Furthermore, the use of positioning boxes and motors in traditional fixed brackets can easily cause concrete to seep into them during pouring, damaging the brackets and rendering them unusable. At the same time, the procurement and maintenance costs are high, and multiple positioning brackets are required for long-distance ditch support, further increasing the cost of use and hindering widespread application. Therefore, to address the above problems, a concrete ditch construction formwork fixing device is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, and to address the problems of fixed support angles leading to limited support ranges, high maintenance costs, and inconvenience for widespread application, this utility model proposes a concrete ditch construction formwork fixing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a concrete side ditch construction formwork fixing device of this utility model includes a crossbeam, two No. 1 limiting shafts are fixedly connected to both sides of the crossbeam, a No. 1 hollow rod is rotatably installed on each of the No. 1 limiting shafts, a No. 1 telescopic rod is slidably arranged inside each of the No. 1 hollow rods, and a No. 1 guide rail is fixedly connected to the outer wall of each of the No. 1 telescopic rods.

[0007] A threaded sleeve is fixedly connected through the crossbeam. A lead screw is threadedly connected to the threaded sleeve. A linkage plate is rotatably installed at the bottom end of the lead screw. A connecting rod is fixedly connected to the two opposite sides of the linkage plate. A slider is fixedly connected to the end of each connecting rod. The four sliders are slidably mounted on the four guide rails.

[0008] Two guide rails are fixed to opposite sides of the crossbeam. A slider is slidably mounted on the guide rail. A limiting shaft is connected to the slider. A hollow rod is rotatably mounted on the limiting shaft. A telescopic rod is slidably mounted inside the hollow rod. The ends of the two telescopic rods on the same side of the crossbeam are rotatably connected to the ends of the two telescopic rods on the first side.

[0009] Preferably, a connecting block is fixed on the second slider, and a second threaded sleeve is fixed through the side of each connecting block. A second lead screw is threadedly connected to each of the second threaded sleeves, and the second lead screw is rotatably mounted on the side wall of the crossbeam. One end of the rotation center axis of the second lead screw is fixed to a turntable.

[0010] Preferably, guide grooves are respectively opened on the crossbeam and on both sides of the first threaded sleeve. Each guide groove is slidably provided with a sliding seat. Each sliding seat is provided with a through hole, and a plug rod is inserted through each through hole.

[0011] Preferably, a limit groove is provided on the side of the first telescopic rod, and a second turntable is fixedly connected to the top of the first lead screw.

[0012] Preferably, a through hole is provided on the side wall of the first hollow rod, and a nut is fixed on the side wall of the first hollow rod and directly opposite the outside of the through hole.

[0014] The advantages of this utility model are:

[0015] 1. This utility model uses the extension and retraction of the No. 1 lead screw to push the linkage plate up and down, thereby driving the rotating shafts on both sides to move synchronously. This allows the end of the component connected to the rotating shaft to abut against the bottom template of the slope, thus fixing the bottom template of the slope with different widths. The No. 2 slider slides on the No. 2 guide rail, which causes the No. 2 hollow rod and the No. 2 telescopic rod to rotate around the rotating shaft. This allows the No. 2 hollow rods on both sides to rotate and fit against the templates on both sides of the slope, thus fixing the side templates of the slope.

[0016] 2. This utility model avoids the use of motors and long-distance wiring on construction sites, improving ease of use while reducing construction and maintenance costs, thus facilitating widespread adoption. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-6 As shown, a concrete side ditch construction formwork fixing device includes a crossbeam 1. Two first-level limiting shafts 2 are fixedly connected to both sides of the crossbeam 1. A first-level hollow rod 3 is rotatably installed on each of the first-level limiting shafts 2. A first-level telescopic rod 4 is slidably arranged inside each of the first-level hollow rods 3. A first-level guide rail 5 is fixedly connected to the outer wall of each of the first-level telescopic rods 4.

[0027] A threaded sleeve 6 is fixedly connected through the crossbeam 1. A lead screw 7 is threadedly connected to the threaded sleeve 6. A linkage plate 29 is rotatably installed at the bottom end of the lead screw 7. A connecting rod 8 is fixedly connected to the two opposite sides of the linkage plate 29. A slider 9 is fixedly connected to the end of the connecting rod 8. The four sliders 9 are slidably mounted on the four guide rails 5 respectively.

[0028] Two second guide rails 10 are fixedly connected to opposite sides of the crossbeam 1. A second slider 11 is slidably mounted on the second guide rail 10. A second limiting shaft 13 is connected to the second slider 11. A second hollow rod 14 is rotatably mounted on the second limiting shaft 13. A second telescopic rod 15 is slidably mounted inside the second hollow rod 14. The two second telescopic rods 15 located at the same end of the crossbeam 1 are rotatably connected to the ends of the two first telescopic rods 4 by a rotating shaft 16.

[0029] A connecting block 12 is fixed on the second slider 11. A second threaded sleeve 17 is fixed through the side of the connecting block 12. A second lead screw 18 is threadedly connected to the second threaded sleeve 17. The second lead screw 18 is rotatably mounted on the side wall of the crossbeam 1. One end of the rotation center axis of the second lead screw 18 is fixed to a turntable 19.

[0030] Guide grooves 24 are respectively provided on the crossbeam 1 and on both sides of the first threaded sleeve 6. Each guide groove 24 is slidably provided with a sliding seat 25. Each sliding seat 25 is provided with a through hole 26. Each through hole 26 is provided with a plug rod 27.

[0031] Limiting grooves 20 are provided on the side of the first telescopic rod 4, and the top of the first lead screw 7 is fixedly connected to the second turntable 28.

[0032] A through hole is provided on the side wall of the first hollow rod 3. A nut 21 is fixed on the side wall of the first hollow rod 3 and directly opposite the outside of the through hole. A bolt 22 is provided through the nut 21, and the thread of the bolt 22 extends through and is provided in the limiting groove 20.

[0033] The four second guide rails 10 are located on the outside of the first limiting shafts 2 on both sides. The ends of the first limiting shaft 2, the second limiting shaft 13 and the rotating shaft 16 are all fixed with baffles 23 for limiting.

[0034] During operation, the existing ditch template positioning brackets, due to their fixed support angles, cannot adapt to the construction requirements of different slope angles, resulting in a limited angle support range. Furthermore, the use of motors leads to high procurement and maintenance costs for the brackets. When supporting long-distance ditches, multiple positioning brackets are required, further increasing the cost of use and hindering widespread application. In this solution, the crossbeam 1 is horizontally spanned across the slope, and the insert rod 27 is inserted through the through hole 26, with its bottom end inserted into the soil on both sides of the slope to fix the device. Subsequently, the extension lengths of the first hollow rod 3 and the first telescopic rod 4, as well as the second hollow rod 14 and the second telescopic rod 15, are adjusted to accommodate the fixing of ditch templates at different depths. The angles between the second hollow rod 14 and the second telescopic rod 15 and the crossbeam 1 are adjusted to accommodate the fixing of slope templates at different angles.

[0035] By rotating the second turntable 28, under the threaded connection between the first lead screw 7 and the first threaded sleeve 6, and the limiting action of the connecting rod 8 on the linkage plate 29, the first lead screw 7 extends and retracts within the first threaded sleeve 6 during rotation. The extension and retraction of the first lead screw 7 pushes the linkage plate 29 up and down. At this time, under the sliding connection between the first slider 9 and the first guide rail 5, the lifting and lowering of the linkage plate 29 will simultaneously drive the four first hollow rods 3 to rotate. The ends of the four first hollow rods 3 will simultaneously contract inwards and expand outwards, thereby driving the rotating shafts 16 on both sides to move synchronously, adjusting the distance between the ends of the first telescopic rods 4 on both sides, and coordinating with the adjustment of the first telescopic rods. 4. The telescopic length within the first hollow rod 3 is adjusted, and the first telescopic rod 4 is locked within the first hollow rod 3 using bolts 22 to fix the length of both. This allows the end of the component connected to the rotating shaft 16 to abut against the bottom template of the slope and be located at the corner between the bottom template and the side template. This enables the fixing of bottom templates of slopes of different widths. When the length and angle of the first hollow rod 3 and the first telescopic rod 4 are adjusted, the rotation angle of the second hollow rod 14 and the extension length of the second telescopic rod 15 within the second hollow rod 14 will be adaptively adjusted with the movement of the rotating shaft 16 to meet the needs of fixing the bottom template of the slope.

[0036] In addition, the lengths and angles of the first hollow rod 3 and the first telescopic rod 4 are fixed, and the ends of the first telescopic rod 4 and the second telescopic rod 15 connected by the rotating shaft 16 are both abutted against the bottom template of the slope. At this time, the rotating shaft 16 cannot move under the restriction of the first hollow rod 3 and the first telescopic rod 4. By rotating the first turntable 19, the first turntable 19 will drive the second lead screw 18 to rotate. Under the threaded connection between the second lead screw 18 and the second threaded sleeve 17, the second slider 11 slides on the second guide rail 10, which will drive the second hollow rod 14 and the second telescopic rod 15 to rotate around the rotating shaft 16. Since the rotating shaft 16 is at the corner of the bottom and side of the slope, the second hollow rod 14 on both sides can be rotated and attached to the templates on both sides of the slope to fix the slope templates. Thus, the device can be used to support and fix slope templates at different angles.

[0037] Moreover, compared with traditional slope formwork fixing brackets, it has lower usage and maintenance costs, avoids the use of motors, avoids long-distance wiring on the construction site, improves ease of use, reduces construction costs, and facilitates widespread use;

[0038] It effectively supports and fixes slope formwork, and can be used for fixing slope formwork at different angles, thus improving ease of use and reducing costs, making it more widely applicable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
