Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to an adjustable fixing clamp for supporting building formwork. Background Technology
[0002] Construction formwork is a temporary support structure used to shape concrete components during construction. Its quality and design directly affect the dimensional accuracy, surface quality, and construction safety of the concrete components. It provides precise geometry for concrete pouring, ensuring that the component dimensions meet design requirements. Standardized formwork can be reused, reducing on-site processing and shortening the construction period.
[0003] Adjustable fixing clamps for building formwork support are the core components for achieving adjustable height, load transfer, and structural stability of the formwork system. The clamps convert the formwork load into axial pressure on the uprights through top support. The adjustment mechanism must ensure that the load is transferred along the axis of the uprights to avoid eccentric bending moments.
[0004] In existing technologies, the weight of freshly poured concrete and construction load borne by the formwork are transmitted to the adjustment mechanism of the clamps through the secondary ribs, and then converted into axial pressure by the uprights, and finally distributed to the foundation by the base. However, in the construction of high formwork, the eccentric load of the clamps causes the uprights to become unstable, resulting in local collapse. The long plate and the hydraulic rod are connected by ball joints to automatically compensate for installation deviations, but the size of the clamps is fixed and cannot adapt to different specifications of formwork and support spacing. Frequent replacement of parts is required, resulting in low construction efficiency. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an adjustable fixing clamp for building formwork support, which aims to improve the problems of fixed clamp size in the prior art, which cannot adapt to different specifications of formwork and support spacing, requires frequent replacement of parts, and results in low construction efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable fixing clamp for supporting building formwork, comprising a fixing plate, a slide rail I fixedly connected to the front side of the top wall of the fixing plate, a clamping mechanism installed on the outer wall of the slide rail I, the clamping mechanism being used to fix the formwork, and a vibration damping mechanism installed on the inner side of the clamping mechanism, the vibration damping mechanism being used to reduce the impact of vibration on the structure; the clamping mechanism includes a long plate, the long plate being slidably connected to the outer wall of the slide rail I, and multiple slide rails II being fixedly connected at equal intervals on the left and right sides of the top wall of the long plate, an mounting plate being slidably connected to the outer wall of the slide rail II, and a clamping plate being fixedly connected to the top wall of the mounting plate.
[0007] As a further description of the above technical solution: A connecting plate is rotatably connected to the middle of the top wall of the long plate, and connecting rods are rotatably connected to the left and right sides of the top wall of the connecting plate. The ends of the connecting rods are rotatably connected to the outer wall of the mounting plate, and a driving assembly is installed at the bottom of the long plate.
[0008] As a further description of the above technical solution: The drive assembly includes a helical gear one, which is fixedly connected to the middle of the bottom wall of the connecting plate. Multiple limiting plates are fixedly connected at equal intervals to the middle of the bottom wall of the long plate. A helical gear two is meshed with the front side of the outer wall of the helical gear one. The helical gear two is rotatably connected to the inner wall of the limiting plate. A turntable is fixedly connected to the right end of the helical gear two.
[0009] As a further description of the above technical solution: The vibration damping mechanism includes a fixing block, which is fixedly connected to the upper part of the outer wall of the clamping plate, and a buffer assembly is installed on the left side of the outer wall of the fixing block.
[0010] As a further description of the above technical solution: The buffer assembly includes damping rods, which are fixedly connected at equal intervals to the left side of the outer wall of the fixing block one, and springs are installed on the outer wall of the damping rods.
[0011] As a further description of the above technical solution: The end of the damping rod is fixedly connected to a second fixing block, and the left side of the outer wall of the second fixing block is fixedly connected to a clamping block, and the top wall of the clamping block is fixedly connected to a limit rod.
[0012] As a further description of the above technical solution: A fixing rod is fixedly connected to the rear side of the inner wall of the fixing plate, and a hydraulic cylinder is installed in the middle of the top wall of the fixing rod.
[0013] As a further description of the above technical solution: A hydraulic rod is installed at the front end of the hydraulic cylinder, and the hydraulic rod is connected to the long plate.
[0014] This utility model has the following beneficial effects: 1. In this utility model, rotating the turntable drives helical gear two, which in turn drives helical gear one, thereby causing the connecting plate to rotate on the top wall of the long plate. When the connecting plate rotates, it pulls the connecting rod, causing the connecting rod to rotate on the top wall of the connecting plate and drive the mounting plate to slide on the outer wall of the slide rail two. When the mounting plate slides, the clamping plate can converge towards the center to clamp and fix the building template. It can adapt to templates of different specifications and support spacing, eliminating the need for frequent replacement of parts and improving construction efficiency.
[0015] 2. In this utility model, after the clamping plates converge towards the center, the clamping blocks clamp the two sides of the template. The template shakes and compresses the clamping blocks, which in turn compress the damping rod. The damping rod then compresses the spring. When the spring is subjected to vibration, it undergoes elastic deformation, absorbing and buffering vibration energy. This effectively isolates vibration, preventing components from loosening, wearing, or even being damaged due to long-term vibration, and extending the service life of the structure.

[0018] 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 protection scope of the present utility model.
[0019] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an adjustable fixing clamp for supporting building formwork, comprising a fixing plate 1, a slide rail 2 fixedly connected to the front side of the top wall of the fixing plate 1, a clamping mechanism 3 installed on the outer wall of the slide rail 2 for fixing the formwork, and a vibration damping mechanism 4 installed on the inner side of the clamping mechanism 3 for reducing the impact of vibration on the structure; the clamping mechanism 3 includes a long plate 304, which is slidably connected to the outer wall of the slide rail 2, and multiple slide rails 303 are fixedly connected at equal intervals on the left and right sides of the top wall of the long plate 304. An mounting plate 302 is slidably connected to the outer wall of the slide rails 303, and a clamping plate 301 is fixedly connected to the top wall of the mounting plate 302. A connecting plate 307 is rotatably connected to the middle of the top wall. Connecting rods 306 are rotatably connected to the left and right sides of the top wall of the connecting plate 307. The ends of the connecting rods 306 are rotatably connected to the outer wall of the mounting plate 302. A drive assembly 305 is installed at the bottom of the long plate 304. The drive assembly 305 includes a helical gear 3051. The helical gear 3051 is fixedly connected to the middle of the bottom wall of the connecting plate 307. Multiple limiting plates 3054 are fixedly connected at equal intervals to the middle of the bottom wall of the long plate 304. A helical gear 3053 is meshed with the front side of the outer wall of the helical gear 3051. The helical gear 3053 is rotatably connected to the inner wall of the limiting plate 3054. A turntable 3052 is fixedly connected to the right end of the helical gear 3053. Specifically, rotating the turntable 3052 drives the second helical gear 3053, which in turn drives the first helical gear 3051, thereby causing the connecting plate 307 to rotate on the top wall of the long plate 304. When the connecting plate 307 rotates, it pulls the connecting rod 306, causing the connecting rod 306 to rotate on the top wall of the connecting plate 307 and drive the mounting plate 302 to slide on the outer wall of the second slide rail 303. When the mounting plate 302 slides, the clamping plate 301 can converge towards the center to clamp and fix the building formwork. This can adapt to different specifications of formwork and support spacing, eliminating the need for frequent replacement of parts and improving construction efficiency.
[0020] Reference Figure 1 , Figure 4 and Figure 5 The vibration damping mechanism 4 includes a first fixed block 401, which is fixedly connected to the upper part of the outer wall of the clamping plate 301. A buffer assembly 402 is installed on the left side of the outer wall of the first fixed block 401. The buffer assembly 402 includes a damping rod 4021, which is fixedly connected at equal intervals to the left side of the outer wall of the first fixed block 401. A spring 4022 is installed on the outer wall of the damping rod 4021. A second fixed block 403 is fixedly connected to the end of the damping rod 4021. A clamping block 404 is fixedly connected to the left side of the outer wall of the second fixed block 403. A limit rod 405 is fixedly connected to the top wall of the clamping block 404.
[0021] Specifically, after the clamping plate 301 converges towards the center, the clamping block 404 clamps the two sides of the template. The template shakes and compresses the clamping block 404, which in turn compresses the damping rod 4021. The damping rod 4021 then compresses the spring 4022. When the spring 4022 is subjected to vibration, it undergoes elastic deformation, absorbing and buffering vibration energy. This effectively isolates vibration, preventing components from loosening, wearing, or even being damaged due to long-term vibration, thus extending the service life of the structure.
[0022] Reference Figure 1 , Figure 2 and Figure 3 A fixing rod 5 is fixedly connected to the rear side of the inner wall of the fixing plate 1. A hydraulic cylinder 6 is installed in the middle of the top wall of the fixing rod 5. A hydraulic rod 7 is installed at the front end of the hydraulic cylinder 6. The hydraulic rod 7 is connected to the long plate 304.
[0023] Specifically, the fixed plate 1 mainly undertakes the functions of template support and positioning. The hydraulic cylinder 6 drives the hydraulic rod 7 to move. Through the extension and retraction of the hydraulic rod 7, precise horizontal displacement adjustment is achieved. At the same time, the lateral pressure on the template is evenly transmitted to the fixed plate 1 to ensure the stability and reliability of the entire support system.
[0024] Working Principle: Rotating turntable 3052 drives helical gear 3053, which in turn transmits power to helical gear 3051, thus rotating it. This series of transmission processes ultimately causes connecting plate 307 to rotate on the top wall of long plate 304. When connecting plate 307 starts to rotate, it pulls connected rod 306, causing it to rotate on the top wall of connecting plate 307. This, in turn, causes mounting plate 302 to slide on the outer wall of slide rail 303. The sliding motion of mounting plate 302 allows clamping plate 301 to converge towards the center, thus clamping and fixing the formwork. This design can adapt to different specifications of formwork and support spacing, eliminating the need for frequent replacement of parts and greatly improving construction efficiency. As the clamping plate 301 converges towards the center, the clamping block 404 tightly clamps both sides of the template, ensuring the stability of the template. When the template shakes, the clamping block 404 is compressed, which in turn compresses the damping rod 4021. The damping rod 4021 then transmits the pressure to the spring 4022. When subjected to vibration, the spring 4022 undergoes elastic deformation. This elastic deformation absorbs and buffers vibration energy, effectively isolating vibration and preventing loosening, wear, or even damage of components due to long-term vibration, thereby extending the service life of the entire structure. This design not only improves the stability and durability of the system but also reduces maintenance costs and enhances overall performance.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
