Description

Technical Field

[0002] In building construction, steel formwork is widely used for the forming and support of concrete structures, and the stability of its connections directly affects construction efficiency and project quality.

Fixed connections are difficult to adapt to different steel formwork spacings or angles, require customized components, have poor flexibility, and welding or complex bolt structures are cumbersome to disassemble, have high reuse costs, and are prone to damaging the formwork. Single-point locking can easily lead to excessive local stress, insufficient overall strength when multiple formworks are spliced, and rigid connections are prone to deformation due to stress concentration or formwork displacement caused by loose bolts, affecting structural accuracy.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1-4 A steel formwork locking structure includes mounting plates 1. A pair of mounting plates 1 are respectively fixedly installed on two adjacent steel formworks by bolts. The mounting plates 1 provide the installation foundation and support points for the entire locking structure, enabling the locking mechanism to reliably connect with the steel formwork and ensuring a stable connection between the locking structure and the steel formwork. This ensures that subsequent locking operations can effectively lock the steel formwork and is the basis for the entire locking structure to function. Each pair of mounting plates 1 is connected by a locking mechanism, which includes a pair of locking plates 2. One locking plate 2 is rotatably connected to one mounting plate 1, and the other locking plate 2 is hooked to another mounting plate 1. The two locking plates are rotatably connected to each other. 2. By using a rotating connection and hooking mechanism, adjacent steel templates are connected and locked, providing an installation position for the stabilizing threaded rod 4. The force applied by the stabilizing threaded rod 4 clamps the steel template. As a key component for locking, its rotating and hooking design makes the installation and disassembly process more convenient, enabling the quick connection or separation of adjacent steel templates, thus improving construction efficiency. A pair of locking plates 2 are connected in a figure-eight shape. Through the rotating connection between the locking plates 2, the angle can be automatically adjusted according to the size difference of the template, enhancing the structural tolerance. The outer wall of the locking plate 2 has a connecting hole 3, and the inner wall of the connecting hole 3 is slidably connected to the stabilizing threaded rod 4. The stabilizing threaded rod 4 applies a clamping force to the locking plates 2.

[0021] Please see Figure 2-4 A connecting plate 5 is fixedly connected to one side of a locking plate 2, and a rotating shaft 6 is fixedly connected to one side of the connecting plate 5. The rotating shaft 6 passes through another locking plate 2 and can rotate relative to it. The connecting plate 5 is fixed to one locking plate 2, and the rotating shaft 6 passes through another locking plate 2 and can rotate relative to it, realizing the rotational connection between the two locking plates 2. This rotational connection method increases the flexibility of the locking structure, allowing the locking plate 2 to be adjusted according to the actual position and angle of the steel template during installation, and better adapting to different construction conditions.

[0022] Please see Figure 4 The outer wall of the stabilizing threaded rod 4 is threaded with stabilizing nuts 7. The two stabilizing nuts 7 are located on both sides of the locking plate 2. The connecting hole 3 is opened in the middle position of the vertical direction of the locking plate 2. The stabilizing threaded rod 4 passes through the connecting hole 3 of the locking plate 2. Through the stabilizing nuts 7 threaded on its outer wall, and the two stabilizing nuts 7 located on both sides of the locking plate 2, a clamping force is applied between the locking plates 2. The stabilizing nuts 7 can be adjusted as needed to precisely control the clamping force on the steel template, ensure the tightness and stability of the connection between the steel templates, and prevent loosening during construction.

[0023] Please see Figure 2One of the mounting plates 1 is fixedly connected to a fixing plate 8 on one side. A rotating shaft 9 is rotatably connected to the outer wall of the fixing plate 8. An adjusting threaded rod 10 is slidably connected through the outer wall of the rotating shaft 9. One end of the adjusting threaded rod 10 is fixedly connected to one side of the locking plate 2. The adjusting threaded rod 10 is located on the upper and lower sides of the fixing plate 8. Two adjusting nuts 11 are threadedly connected to the outer wall of the adjusting threaded rod 10. The two adjusting nuts 11 are located on both sides of the rotating shaft 9. The fixing plate 8 is fixed on the mounting plate 1. The rotating shaft 9 rotates on the fixing plate 8. The adjusting threaded rod 10 passes through the rotating shaft 9 and is fixed to the locking plate 2. The adjusting nuts 11 are located on both sides of the rotating shaft 9. The position of the adjusting threaded rod 10 on the rotating shaft 9 can be adjusted by adjusting the adjusting nuts 11, thereby realizing the fine adjustment of the position of the locking plate 2. It can adapt to steel formwork of different thicknesses and the dimensional deviations that may occur during construction, improving the versatility and adaptability of the locking structure and ensuring that the steel formwork can be accurately locked under various conditions.

[0024] Please see Figure 3 A hook block 12 is fixedly connected to one side of another mounting plate 1, and a hook rod 13 is fixedly connected to one side of the locking plate 2. The hook block 12 and the hook rod 13 are connected. The hook rod 13 is U-shaped. The hook block 12 is fixed on a mounting plate 1, and the hook rod 13 is fixed on the locking plate 2. The two are connected together, realizing the hooking between the locking plate 2 and the mounting plate 1. This hooking method makes the installation and disassembly of the locking structure more convenient and quick, and at the same time provides a certain connection strength to ensure the reliability of the locking structure.

[0025] In use, a pair of mounting plates 1 are fixed to the edges of two adjacent steel templates with bolts, serving as the basic support for the entire locking structure. One locking plate 2 is hinged to the mounting plate 1 via a connecting plate 5 and a rotating shaft 6, allowing it to rotate around the rotating shaft 6. The other locking plate 2 is hooked to the hook block 12 of another mounting plate 1 via a U-shaped hook rod 13, forming a detachable mechanical connection. The two locking plates 2 are connected by a stabilizing threaded rod 4 through a connecting hole 3 and tightened by stabilizing nuts 7 on both sides. When the nuts are rotated, the threaded rod applies a pulling force towards the center to the two locking plates 2, causing the locking plates 2 to close along the axis of the threaded rod, thereby clamping the two steel templates. The locking plates 2 are connected in a "V" shape. During clamping, the angle can be automatically adjusted according to unevenness or dimensional deviation of the template surface to ensure uniform force. The rotating shaft 9 is connected to the mounting plate 1 via a fixing plate 8. The adjusting threaded rod 10 passes through the rotating shaft 9 and is fixed to the locking plate 2. Rotating the adjusting nut 11 allows for fine adjustment of the position of the locking plate 2 in the horizontal direction to compensate for differences in template thickness or installation errors. The hooking design of the U-shaped hook rod 13 and the hooking block 12 restricts the lateral movement of the locking plate 2, preventing the template from shifting due to lateral pressure during the pouring process. Loosen the stabilizing nut 7 and the adjusting nut 11 to release the clamping force of the threaded rod, disengage the U-shaped hook rod 13 at the hooking end from the hooking block 12, and rotate the locking plate 2 to separate it from the steel template to complete the disassembly.
