[0002] Aluminum alloy formwork is a type of formwork suitable for concrete engineering, made primarily of aluminum alloy profiles through machining and welding processes. Designed according to a 50mm module, it consists of panels, ribs, main profiles, flat formwork, corner formwork, and early stripping devices. During use, multiple aluminum formwork panels are often connected using fastening devices to facilitate their operation.

[0003] Existing patents, such as CN 222140715 U, disclose a fastening device for aluminum formwork in construction. This device, through the arrangement of insert plates, slots, connecting plates, pin holes, pin rods, positioning holes, drive boxes, hand dials, rotating shafts, first gears, second gears, driven shafts, bidirectional gearboxes, fixed cylinders, first bevel gears, second bevel gears, threaded rods, and internally threaded sleeves, allows for the rapid and secure connection of multiple aluminum formwork bodies via a locking mechanism. It also reduces the labor intensity of operators through labor-saving components, significantly improving the connection tightness and efficiency, and thus greatly enhancing its practicality. However, after connecting multiple aluminum formworks, the aforementioned fastening device lacks a structure to lock and secure the locking mechanism. This means that during use, when the hand dial is subjected to external force, it often rotates, causing the locking mechanism to separate, resulting in the separation of multiple aluminum formworks. This prevents stable connection of multiple aluminum formworks, thus hindering the secure installation and use of the aluminum formwork. Utility Model Content

[0004] This utility model proposes a fastening device for building aluminum formwork to solve the problem that when the hand dial of the existing fastening device is subjected to external force during use, it often rotates, causing the locking mechanism to separate, resulting in the separation of multiple aluminum formworks and the inability to achieve a stable connection of multiple aluminum formworks.

[0006] Preferably, the elastic element includes a storage cavity formed inside the connecting frame and a pull rod movably inserted into the connecting frame. One end of the pull rod is fixedly connected to the top of the plug block, and the other end is equipped with a handle. A second spring is also connected between the bottom of the plug block and the inner wall of the storage cavity, and the second spring is sleeved on the outside of the pull rod.

[0007] Preferably, the bottom of the connecting block and the top of the plug-in block are beveled to form mutually matching bevels.

The two cavities are symmetrically distributed on both sides of the plug-in hole, and a first spring is fixed inside each of the two cavities. One end of each of the two first springs is connected to a movable plate, and a limiting block that can extend into the plug-in hole is fixed on one side of each of the two movable plates. Limiting holes that cooperate with the limiting blocks are opened on both sides of the plug-in block.

[0009] Preferably, the connecting frame is further provided with a positioning component for quickly positioning the connecting block, and the positioning component includes two cavities opened inside the connecting frame.

Detailed Implementation

[0025] 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.

[0026] This utility model provides, for example Figures 1-9 The above describes a fastening device for building aluminum formwork, which includes an aluminum formwork body 1. Extension plates 2 are fixed on both sides of the bottom of the aluminum formwork body 1. Two symmetrically distributed connecting blocks 3 are installed on one side of one of the extension plates 2, and two symmetrically distributed connecting frames 5 are fixed on one side of the other extension plate 2. Each of the two connecting frames 5 has a connecting cavity 7 for inserting the connecting blocks 3, and each of the two connecting cavities 7 is provided with a plug-in block 8. Each of the two connecting blocks 3 has a plug-in hole 4 for inserting the plug-in block 8. Each of the two connecting frames 5 is provided with an elastic element that drives the plug-in block 8 to rise and fall.

[0027] The elastic element includes a storage cavity 18 opened inside the connecting frame 5 and a pull rod 9 movably inserted into the connecting frame 5. One end of the pull rod 9 is fixedly connected to the top of the plug block 8, and the other end is equipped with a handle. A second spring 13 is also connected between the bottom of the plug block 8 and the inner wall of the storage cavity 18, and the second spring 13 is sleeved on the outside of the pull rod 9.

[0028] As described above, when using aluminum templates, multiple aluminum templates can be spliced ​​together sequentially, so that the connecting block 3 on one side of one aluminum template body 1 is inserted into the connecting cavity 7 in the connecting frame 5 on the other side of another aluminum template body 1. At this time, the connecting block 3 pushes the insertion block 8 upward, so that the insertion block 8 squeezes and contracts the second spring 13 until the connecting block 3 is completely inserted into the interior of the connecting cavity 7. When the insertion block 8 corresponds to the insertion hole 4, the second spring 13 pushes the insertion block 8, so that the insertion block 8 is inserted into the insertion hole 4, thereby fixing the connecting block 3 and realizing the quick connection of two adjacent aluminum template bodies 1. Then, repeating the above steps can realize the sequential connection of multiple aluminum template bodies 1, thereby realizing the quick connection of aluminum template bodies 1 and facilitating the use of aluminum template bodies 1.

[0029] Furthermore, when the aluminum template body 1 needs to be disassembled after use, the pull rod 9 can be pulled to move the plug block 8 out of the plug hole 4 until the plug block 8 is pulled into the storage cavity 18. At the same time, the plug block 8 compresses and contracts the second spring 13, and then the aluminum template body 1 is pulled to move the connecting block 3 out of the connecting cavity 7 in the connecting frame 5, thereby separating two adjacent aluminum template bodies 1. Then, the above steps can be repeated to disassemble multiple aluminum template bodies 1, thereby achieving quick disassembly and assembly of the aluminum template body 1 for easy use.

[0030] Furthermore, such as Figure 1 as well as Figures 3-7As shown, the bottom of the connecting block 3 and the top of the insertion block 8 are beveled to form mutually matching bevels. Based on this, when the connecting block 3 is inserted into the connecting cavity 7 on the connecting frame 5, the connecting block 3 pushes the insertion block 8 upward through the bevel until the connecting block 3 is fully inserted into the connecting cavity 7, thereby facilitating the insertion between the connecting block 3 and the connecting frame 5.

[0031] Additionally, in this embodiment, as Figures 3-7 As shown, the connecting block 3 is also provided with a limiting structure to reinforce the plug-in block 8. The limiting structure includes two cavities opened inside the connecting block 3. The two cavities are symmetrically distributed on both sides of the plug-in hole 4. A first spring 10 is fixed inside each of the two cavities. One end of each of the two first springs 10 is connected to a movable plate 12. A limiting block 11 that can extend into the plug-in hole 4 is fixed on one side of each of the two movable plates 12. Limiting holes 14 that cooperate with the limiting blocks 11 are opened on both sides of the plug-in block 8.

[0032] When the plug-in block 8 is inserted into the plug-in hole 4, the plug-in block 8 presses the limiting block 11 through its side wall, so that the limiting block 11 is under force and presses the first spring 10 through the movable disk 12, so that the first spring 10 contracts and drives the limiting block 11 to retract into the cavity. When the plug-in block 8 is fully inserted into the plug-in hole 4, the limiting block 11 corresponds to the limiting hole 14. At this time, the first spring 10 pushes the limiting block 11 through the movable disk 12, so that the limiting block 11 is locked into the limiting hole 14, thereby realizing the limiting and fixing of the plug-in block 8, which facilitates the stable insertion between the plug-in block 8 and the connecting block 3.

[0033] Meanwhile, in this embodiment, such as Figure 1 , Figure 3 and Figure 5 As shown, the connecting frame 5 is also provided with a positioning component for quickly positioning the connecting block 3. The positioning component includes two cavities opened inside the connecting frame 5. A third spring 15 is fixed inside each of the two cavities. One end of each of the two third springs 15 is connected to a movable disk 16. A positioning block 17 that can extend into the connecting cavity 7 is installed on one side of each of the two movable disks 16. A positioning hole 6 that cooperates with the positioning block 17 is opened on the top of the connecting block 3.

[0034] When the connecting block 3 is inserted into the connecting cavity 7 inside the connecting frame 5, the connecting block 3 will squeeze the positioning block 17, so that the positioning block 17 is under force and squeezes the third spring 15 through the moving disk 16, causing the third spring 15 to contract, so as to drive the positioning block 17 into the cavity until the connecting block 3 is completely inserted into the connecting cavity 7. At this time, the positioning block 17 corresponds to the positioning hole 6. Then, under the action of the third spring 15, the positioning block 17 is pushed by the moving disk 16, so that the positioning block 17 is inserted into the positioning hole 6, so as to realize the quick positioning of the connecting block 3 in the connecting cavity 7, thereby facilitating the stable insertion between the connecting block 3 and the connecting frame 5.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
