Technical Field
[0001] This utility model relates to the field of highway formwork tools, specifically a formwork support device for highway engineering. Background Technology
[0002] In highway construction, formwork support is used to ensure the quality of concrete pouring and the accuracy of highway structural dimensions. Common support methods in existing technologies include:
[0003] Timber beams with steel pipe diagonal bracing: Timber beams are temporarily nailed on-site and then supported diagonally with steel pipes or reinforcing bars. This method involves a variety of materials and specifications, resulting in arbitrary installation and problems such as loose supports, formwork displacement, and formwork bulging. Furthermore, the timber beams have a low turnover rate, leading to significant waste.
[0004] Fixed steel back bracing: This type of bracket is made of steel welded into a fixed height, such as a portal or triangular support. Although it has good rigidity, its position is not adjustable. It is not universally applicable when encountering widened or irregular curved surfaces, and additional irregular parts need to be processed, which increases costs and time.
[0005] Simple spiral jack: Nuts are welded to the back of the steel formwork, and the screws support the ground to achieve single-point support. This method can only provide vertical force and has insufficient lateral restraint on the formwork, making it prone to horizontal displacement during pouring and vibration; moreover, the exposed screws are prone to corrosion and have poor adjustment accuracy.
[0006] Therefore, existing support devices have a single support form, making it difficult to adapt to templates of different widths and irregular shapes. On-site installation and dismantling are cumbersome, turnover efficiency is low, support stability is insufficient, and bulging and displacement of the template are prone to occur, affecting the quality of concrete molding. The components are scattered and easily lost on-site, resulting in high management costs. In order to address the shortcomings of existing technologies, this utility model provides a template support device for highway engineering to solve the above problems. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0031] This utility model discloses a formwork support device for highway engineering, according to the attached... Figure 1-5As shown, it includes a support plate 1, a fixed base plate 2 fixedly connected to the support plate 1, and a storage box 3 fixedly connected to the support plate 1. An adjustment platform 4 is movably engaged inside the storage box 3, and the adjustment platform 4 can be moved and adjusted within the storage box 3. A split frame 5 is fixedly connected to the adjustment platform 4, and a second-side clamping platform 6 is provided on the split frame 5. The second-side clamping platform 6 is used to clamp and fix the template in a second-side manner.
[0032] According to the appendix Figure 5 As shown, the storage box 3 is further provided with an adjustment unit 7 for adjusting the adjustment platform 4. The adjustment unit 7 includes a lead screw 71 and a guide rod 72. The lead screw 71 is threadedly connected to the storage box 3 and rotatably connected to the adjustment platform 4. The guide rod 72 is fixedly connected to the adjustment platform 4 and slidably connected to the storage box 3. The principle is as follows: when the lead screw 71 is rotated, since the lead screw 71 is threadedly connected to the storage box 3 and rotatably connected to the adjustment platform 4, and the guide rod 72 restricts the adjustment platform 4 to only make linear movements, the rotation of the lead screw 71 will drive the adjustment platform 4 to move along the direction of the guide rod 72, thereby realizing the adjustment of the position of the adjustment platform 4.
[0033] According to the appendix Figure 2 , 5 As shown, the lead screw 71 is further provided with a rotating handle 711. By rotating the rotating handle 711, the lead screw 71 can be rotated more conveniently and effortlessly, thereby adjusting the position of the adjusting table 4.
[0034] According to the appendix Figure 1 , 3 As shown in Figure 4, the second-side clamping platform 6 can be either a planar structure or a curved structure. The planar structure of the second-side clamping platform 6 is suitable for clamping planar templates; the curved structure of the second-side clamping platform 6 is suitable for clamping curved templates, and the choice can be made according to the shape of the template in the actual project.
[0035] According to the appendix Figure 3 , 4 As shown, the second-side pressing table 6 is further provided with a rubber pad 61. The rubber pad 61 can increase the friction between the second-side pressing table 6 and the template, and at the same time play a buffering role to prevent damage to the template during the pressing process.
[0036] According to the appendix Figure 1 As shown, furthermore, a reinforcing rib 21 is fixedly connected between the support plate 1 and the fixed base plate 2. The reinforcing rib 21 can enhance the connection strength between the support plate 1 and the fixed base plate 2 and improve the stability of the entire device. A first fixing hole 22 is provided on the fixed base plate 2. The fixed base plate 2 can be fixed to the ground with bolts or other fasteners through the first fixing hole 22 to ensure that the device will not move during use.
[0037] According to the appendix Figure 3 , 4 As shown in Figure 5, the adjustment platform 4 is further provided with a second fixing hole 41, and the split frame 5 is provided with a third fixing hole 51 corresponding to the position of the second fixing hole 41. By using bolts or other fasteners passing through the second fixing hole 41 and the third fixing hole 51, the split frame 5 can be fixed on the adjustment platform 4 to ensure the stability of the connection between the split frame 5 and the adjustment platform 4.
[0038] According to the appendix Figure 1-5 As shown, the device can precisely adjust the position of the adjustment platform 4 through the adjustment unit 7, thereby adapting to the template support requirements of different positions; secondly, the various structural forms of the clamping platform 6 and the setting of the rubber pad 61 enable the device to better adapt to templates of different shapes and provide stable clamping force.
[0039] According to the appendix Figure 2 , 3 As shown in the diagram, which is disclosed in particular from the top view and the adjustment diagram of the second-side abutment platform 6, the device has a compact overall structure, a reasonable layout, and clear connections between its various components, making it easy to install and disassemble, as well as convenient to operate and adjust in actual engineering projects.
[0040] According to the appendix Figure 1-5 As shown, it is particularly important to emphasize that the storage box 3 provides storage and adjustment space for the adjustment platform 4, making the adjustment process of the adjustment platform 4 more stable and reliable. When the adjustment platform 4, the split frame 5, and the second-side clamping platform 6 are not needed, it is convenient to store the adjustment platform 4, the split frame 5, and the second-side clamping platform 6. The design of the split frame 5 makes the installation and replacement of the second-side clamping platform 6 more convenient, improving the versatility and flexibility of the device.
[0041] According to the appendix Figure 1-5 As shown, it is particularly important to emphasize that the design of the reinforcing rib 21, the first fixing hole 22, the second fixing hole 41, and the third fixing hole 51 is to enhance the stability, reliability, and flexibility of the device, and to ensure that the device can be used safely and effectively in highway engineering formwork support.
[0042] The working principle of the formwork support device used in this highway project is as follows:
[0043] First, the base plate 2 is fixed to the ground using bolts or other fasteners through the first fixing hole 22 to ensure the stability of the device. Then, according to the position of the template, the screw 71 is rotated by turning the handle 711, causing the adjusting platform 4 to move up and down along the guide rod 72 to adjust the adjusting platform 4 to a suitable position. Next, a second-side clamping platform 6 with a planar or curved structure is selected according to the shape of the template and installed on the split frame 5. The rubber pad 61 is used to increase the friction and cushioning effect between the platform and the template, so that the second-side clamping platform 6 provides a second-side clamping fixation to the template.
[0044] The steps for using the formwork support device in this highway project are as follows:
[0045] Determine the installation location of the device, place the base plate 2 on the ground, and use bolts to fix the base plate 2 through the first fixing hole 22.
[0046] According to the template position, the support plate 1 is used for support, or the position of the adjustment table 4 is adjusted by rotating the handle 711 so that the adjustment table 4 reaches the appropriate position and is supported by the split frame 5 and the second side clamping table 6.
[0047] Select a suitable second-side abutment platform 6 and install it on the split frame 5.
[0048] The split frame 5 is fixed to the adjusting table 4 by bolts passing through the second fixing hole 41 and the third fixing hole 51, so that the second side pressing table 6 presses against the template.
[0049] The beneficial effects of the formwork support device used in this highway engineering project are as follows:
[0050] Easy to adjust: The position of the adjustment platform 4 can be precisely adjusted through the adjustment unit 7 to adapt to the template support requirements of different positions.
[0051] High adaptability: The support plate 1 provides basic load-bearing capacity. If the support plate 1 does not meet the requirements, the second-side clamping platform 6 provides additional support. The second-side clamping platform 6 has two structural forms: flat and curved. The split frame 5 can quickly replace the second-side clamping platform 6. It can cover straight, widened and curved templates without the need for custom-made irregular parts, and can adapt to templates of different shapes. In addition, the rubber pad 61 increases the friction and cushioning effect between the template and the template.
[0052] Good stability: The design of the reinforcing rib 21, the first fixing hole 22, the second fixing hole 41 and the third fixing hole 51 enhances the stability and reliability of the device.
[0053] Easy installation and disassembly: The design of the split frame 5 makes it easier to install and replace the second-side clamping platform 6, improving the versatility and flexibility of the device.
