Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a reusable concrete formwork fixing device. Background Technology

[0002] Concrete formwork fixing devices are specialized tool systems used in building construction for precise positioning, stable support, and shaping of concrete formwork. Their core function is to ensure that the formwork maintains geometric stability when bearing the self-weight of the concrete, lateral pressure, and construction loads during the pouring process, preventing bulging, displacement, or deformation.

[0003] Traditional concrete formwork fixing devices typically use metal plates for fixation and reuse. However, adjusting the metal plates usually requires workers to use various auxiliary tools to adjust and support them before subsequent concrete pouring. This method is very cumbersome and time-consuming, thus affecting the construction schedule. Utility Model Content

[0004] The purpose of this invention is to provide a reusable concrete formwork fixing device. Specifically, by rotating a threaded knob counterclockwise, the metal plate is released from its fixing position. Then, the handle is pushed and pulled to move the metal plate, adjusting its position. After adjustment, the adjusting plate is locked in place, thus fixing the metal plate. This method allows for quick adjustment of the two metal plates without the need for various auxiliary tools, making operation simpler and more convenient. It solves the problem that adjusting the metal plate typically requires workers to use various auxiliary tools to adjust and support it before subsequent concrete pouring, a process that is cumbersome and time-consuming.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a reusable concrete formwork fixing device, comprising two base plates, wherein a mounting plate is bolted to the top of each base plate, and further comprising:

[0007] The fixing mechanism comprises two sets, each set positioned above the mounting plate. Each fixing mechanism includes a metal plate on the outer side of the mounting plate. An adjusting plate and two limiting rods are fixedly connected to the side of the metal plate facing the mounting plate. A handle is positioned above the adjusting plate, its surface fixedly connected to the surface of the metal plate. A fixing block is fixedly connected to the center of the top of the mounting plate, and a threaded knob is threadedly connected to the top of the fixing block.

[0008] A clamping mechanism is disposed on the top of the metal plate and is used to clamp and fix the two metal plates.

[0009] The adjusting plate is located at the center of the metal plate, and the two limiting rods are located at both ends of the metal plate. The base plate is fixed to the position to be poured using expansion bolts.

[0010] Furthermore, limit plates are fixedly connected to the top left and right sides of the mounting plate, the adjusting plate is slidably connected inside the fixing block, and the threaded knob is used to lock the adjusting plate in place; turning the threaded knob counterclockwise releases the fixing of the metal plate, making it easier to adjust the position of the metal plate.

[0011] Furthermore, the limiting rod slides through the limiting plate and extends to the outside. The limiting rod cooperates with the limiting plate to support and limit the metal plate. When the metal plate is adjusted, it will drive the limiting rod to slide on the limiting plate, so that the metal plate moves horizontally.

[0012] Furthermore, the clamping mechanism includes a fixed frame fixedly connected to the front metal plate, a clamping plate slidably connected to the outside of the fixed frame, a threaded rod threadedly connected to the back of the fixed frame, a throttle fixedly connected to the back of the threaded rod, a square groove opened inside the clamping plate, a limit ring fixedly connected to the back of the clamping plate, and the fixed frame disposed in the square groove of the clamping plate; when the clamping plate contacts the rear metal plate, the clamping plate and the fixed frame cooperate to lock and fix the two metal plates.

[0013] Furthermore, the end of the threaded rod facing the clamping plate is provided with a convex shaft, which is rotatably connected to the inside of the limiting ring. The limiting ring and the convex shaft on the threaded rod cooperate to restrict the threaded rod. The front of the clamping plate contacts the back of the rear metal plate. The fixing frame is square and is used to limit the movement of the clamping plate. Since the convex shaft on the threaded rod rotates inside the limiting ring, the threaded rod can smoothly push or pull the clamping plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model uses a fixing mechanism, specifically, rotating the threaded knob counterclockwise to release the metal plate from its fixation, then pushing and pulling the handle to move the metal plate and adjust its position. After adjustment, the adjusting plate is locked in place, thus fixing the metal plate. This method can quickly adjust the position of the two metal plates without the need for multiple auxiliary tools, making the operation simpler and more convenient.

[0016] 2. This utility model features a clamping mechanism. Specifically, when the throttle is turned clockwise, the convex shaft on the threaded rod will push the clamping plate by cooperating with the limiting ring. When the clamping plate contacts the metal plate behind it, the clamping plate cooperates with the fixing frame to lock and fix the two metal plates, preventing the metal plates from deforming and improving the strength of the metal plates.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figures 1-5 As shown, this utility model is a reusable concrete formwork fixing device, including two base plates 1, with a mounting plate 11 fixedly connected to the top of the base plates 1 by bolts, and also including:

[0028] The fixing mechanism 2 consists of two sets, each positioned above the mounting plate 11. Each fixing mechanism 2 includes a metal plate 21 on the outer side of the mounting plate 11. An adjusting plate 23 and two limiting rods 24 are fixedly connected to the side of the metal plate 21 facing the mounting plate 11. A handle 22 is located on top of the adjusting plate 23, and its surface is fixedly connected to the surface of the metal plate 21. A fixing block 13 is fixedly connected to the center of the top of the mounting plate 11, and a threaded knob 131 is threadedly connected to the top of the fixing block 13. Turning the threaded knob 131 counterclockwise releases the metal plate 21 from its fixing position. Then, pushing or pulling the handle 22 moves the metal plate 21, adjusting its position. After adjustment, the adjusting plate 23 is locked in place, thus fixing the metal plate 21. This method allows for quick adjustment of the positions of the two metal plates 21 without the need for multiple auxiliary tools, making operation simpler and more convenient. The adjusting plate 23 is located at the center of the metal plate 21, and the two limiting rods 24 are located at both ends of the metal plate 21.

[0029] The clamping mechanism 3 is located on the top of the metal plate 21 and is used to clamp and fix the two metal plates 21.

[0030] Limiting plates 12 are fixedly connected to the top left and right sides of the mounting plate 11. Adjusting plate 23 is slidably connected inside the fixing block 13. Threaded knob 131 is used to lock and fix the adjusting plate 23.

[0031] The limiting rod 24 slides through the limiting plate 12 and extends to the outside. The limiting rod 24 cooperates with the limiting plate 12 to support and limit the metal plate 21.

[0032] The clamping mechanism 3 includes a fixed frame 31 fixedly connected to the front metal plate 21. A clamping plate 32 is slidably connected to the outside of the fixed frame 31. A threaded rod 33 is threadedly connected to the back of the fixed frame 31. A handle 34 is fixedly connected to the back of the threaded rod 33. A square groove 321 is opened inside the clamping plate 32. A limit ring 322 is fixedly connected to the back of the clamping plate 32. The fixed frame 31 is set in the square groove 321 on the clamping plate 32. When the handle 34 is rotated clockwise, the convex shaft on the threaded rod 33 will push the clamping plate 32 by cooperating with the limit ring 322. When the clamping plate 32 contacts the rear metal plate 21, the clamping plate 32 and the fixed frame 31 cooperate to lock and fix the two metal plates 21, preventing the metal plates 21 from deforming and improving the strength of the metal plates 21.

[0033] The threaded rod 33 has a convex shaft at one end facing the clamping plate 32. The convex shaft on the threaded rod 33 is rotatably connected to the inside of the limiting ring 322. The limiting ring 322 and the convex shaft on the threaded rod 33 cooperate to restrict the threaded rod 33. The front of the clamping plate 32 contacts the back of the rear metal plate 21. The fixing bracket 31 is square and is used to limit the movement of the clamping plate 32.

[0034] One specific application of this embodiment is:

[0035] In use, the mounting plate 11 is fixed to the base plate 1 with bolts, and the fixing mechanism 2 is installed on the base plate 1. Then, the base plate 1 is fixed to the position to be poured with expansion bolts, and the two base plates 1 with the fixing mechanism 2 are fixed at the same time, and the two metal plates 21 are in a parallel state. Then, the metal plates 21 are adjusted according to the size of the pour. The threaded knob 131 is turned counterclockwise to release the fixing of the metal plate 21. Then, the push and pull handle 22 drives the metal plate 21 to move and adjust the position of the metal plate 21. The metal plate 21 will drive the limit rod 24 to slide on the limit plate 12, and the adjusting plate 23 will slide in the fixing block 13, thereby allowing the metal plate 21 to move horizontally for adjustment. After the adjustment is completed, the threaded knob 131 is turned clockwise to lock the adjusting plate 23, thereby completing the fixing of the metal plate 21. This method can quickly adjust the position of the two metal plates 21 without the need for multiple auxiliary tools, making the operation simpler and more convenient.

[0036] After the metal plate 21 is adjusted, the handle 34 is turned clockwise. The convex shaft on the threaded rod 33 will push the clamping plate 32 through the engagement with the limiting ring 322. The clamping plate 32 will then slide on the fixing frame 31 through the square groove 321. When the clamping plate 32 contacts the rear metal plate 21, the clamping plate 32 and the fixing frame 31 will engage to lock and fix the two metal plates 21, preventing deformation of the metal plates 21 and improving the strength of the metal plates 21. In addition, when demolding is required, the clamping plate 32 can be moved away from the rear metal plate 21 to release the fixation of the two metal plates 21. Then, the mounting plate 11 can be removed from the base plate 1, and the fixing mechanism 2 can be taken out as a whole, so that the device can be reused.
