Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a concrete formwork support device. Background Technology

[0002] Formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components into specified positions and geometric dimensions, maintain their correct position, and bear the weight of the formwork itself and external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete works, accelerate construction progress, and reduce project costs. Building support structures can be square or cylindrical; therefore, formwork used for support can also be circular or square.

[0003] Currently, most concrete formwork support devices can only support and reinforce square support column formwork, such as the "A Concrete Formwork Support Device for Building Beams and Columns" with patent publication number "CN220848723U". However, when it is necessary to support and reinforce formwork with curved outer ends, this device cannot be used, and different support devices need to be replaced. This requires the purchase of multiple support devices, which increases the construction cost. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete formwork support device, comprising: The base plate and the mounting plate are provided with a first threaded rod at the top of the base plate and on the side of the mounting plate near the base plate. A threaded sleeve is provided between the two first threaded rods. One end of each of the two first threaded rods extends from both ends of the threaded sleeve into the inside of the threaded sleeve and is connected to the threaded sleeve by threads. A movable connecting component is provided at the top of the base plate and on the side of the mounting plate near the base plate. The other end of each of the two first threaded rods is connected to the top of the base plate and the side of the mounting plate by the movable connecting component. A support plate is provided on the side of the mounting plate away from the base plate. A T-shaped insertion groove is provided on the side of the mounting plate near the support plate. A T-shaped insertion block is fixedly provided on the side of the support plate near the mounting plate. The T-shaped insertion block is located inside the T-shaped insertion groove. A limiting component is provided at the bottom end of the T-shaped insertion block.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model provides a concrete formwork support device, combined with the attached... Figure 1-7 Its specific structure and implementation method are as follows: Main structural components Base plate 1 and mounting plate 2: Base plate 1 is fixed to the ground by mounting holes 20 and bolts to provide overall stability. Each of the four corners of the top of the base plate 1 is provided with a mounting hole 20. The base plate 1 is fixed to the ground by bolts in conjunction with the mounting holes 20. The mounting plate 2 is located on one side of the base plate 1. The two are connected by a movable connecting component and a threaded adjustment mechanism.

[0022] The threaded adjustment mechanism includes two first threaded rods 3 and a threaded sleeve 4. One end of each first threaded rod 3 is hinged to the base plate 1 and mounting plate 2 via a movable connecting assembly, while the other end extends into the threaded sleeve 4 and engages with it through threads. Rotating the threaded sleeve 4 synchronously adjusts the extension and retraction of the two first threaded rods 3, thereby changing the distance between the mounting plate 2 and the base plate 1 to adapt to the support requirements of templates at different heights. A turntable 15 is fixedly provided at the middle of the outer end of the threaded sleeve 4 for easy manual operation.

[0023] Support plate 5 and limiting component: Support plate 5 is located on the side of mounting plate 2 away from base plate 1, and its contact surface can be flat or curved to suit square or cylindrical templates. A T-shaped insertion slot 6 is provided on the side of mounting plate 2 near support plate 5, and a T-shaped insertion block 7 is fixedly provided on the side of support plate 5 near mounting plate 2. The T-shaped insertion block 7 is fixed on support plate 5 and inserted into the T-shaped insertion slot 6 of mounting plate 2 to achieve lateral limiting.

[0024] The limiting component includes a movable groove 8, a limiting square rod 9, and a second threaded rod 11, all located at the bottom of the T-shaped insertion slot 6. The bottom of the T-shaped insertion block 7 has a limiting square groove 10. The top end of the limiting square rod 9 extends into the limiting square groove 10. The movable groove 8 contains the second threaded rod 11, whose bottom end extends to the bottom of the mounting plate 2 and is rotatably connected to the bottom of the mounting plate 2 via a bearing. The bottom of the limiting square rod 9 has a threaded groove 12, and the top end of the second threaded rod 11 extends into the threaded groove 12 and is threadedly connected to the threaded groove 12. A handle 13 is fixedly mounted on the bottom of the second threaded rod 11. Rotating the handle 13 drives the second threaded rod 11 upward, pushing the limiting square rod 9 into the limiting square groove 10 at the bottom of the support plate 5, achieving vertical fixation and preventing the support plate 5 from falling off.

[0025] As attached Figure 6As shown, the movable connection assembly includes two U-shaped fixing frames 16 fixedly mounted on the top of the base plate 1 and on the side of the mounting plate 2 near the base plate 1. Each U-shaped fixing frame 16 has a movable block 17 inside. The other ends of the two first threaded rods 3 are respectively fixedly connected to the two movable blocks 17. Each movable block 17 has a rotating shaft 18 fixedly mounted at both its front and rear ends. The movable block 17 and the U-shaped fixing frame 16 are rotatably connected via the two rotating shafts 18. The U-shaped fixing frame 16 has a fixing bolt 19, one end of which passes through the U-shaped fixing frame 16 and abuts against the outer end of one rotating shaft 18. The fixing bolt 19 and the U-shaped fixing frame 16 are connected by threads. The U-shaped fixed frame 16 is fixed on the base plate 1 or the mounting plate 2. The movable block 17 is rotatably connected to the U-shaped fixed frame 16 via the rotating shaft 18. The end of the first threaded rod 3 is fixed on the movable block 17. The fixing bolt 19 can lock the rotating shaft 18 and adjust the fixed angle to ensure the stability of the support.

[0026] Anti-slip design: The surface of the support plate 5 is provided with multiple anti-slip grooves 14 to increase the friction with the template and prevent slippage.

[0027] Implementation scenario examples Cylindrical template support: Select the curved support plate 5, insert it into the T-shaped insertion slot 6, tighten the handle 13 to lock it, and adjust the threaded sleeve 4 to make the support plate 5 fit tightly against the template.

[0028] Square template support: Switch to flat support plate 5, and adjust the support angle through the movable connecting components to ensure the verticality of the template.

[0029] This utility model effectively solves the problem of limited applicability of traditional support devices through modular design and adjustable structure, combining economy and practicality. Specifically, this embodiment addresses the issue that existing concrete formwork support devices can mostly only support and reinforce square support column formwork. When it is necessary to support and reinforce formwork with curved outer ends, the device cannot be used, requiring the replacement of different support devices. This necessitates the purchase of multiple support devices, increasing construction costs.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
