Aluminum formwork is designed modularly and extruded using specialized equipment, allowing for free combination according to different structural dimensions. The application of aluminum formwork systems in the construction industry has improved the construction efficiency of building projects, significantly saving on building materials and labor.

[0024] 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.

[0025] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:

[0026] A multi-angle retractable support aluminum formwork corner fastening assembly includes: two aluminum formwork bodies 1; each of the two aluminum formwork bodies 1 has a mounting groove 2 in the middle of an adjacent side, and a first mounting plate 3 and a second mounting plate 4 respectively embedded in the two mounting grooves 2; fasteners 5 are fixedly connected to both sides of the first mounting plate 3 and the second mounting plate 4; circular holes 6 are opened on the first mounting plate 3 and the second mounting plate 4 near the fasteners 5, and corresponding fasteners 7 are embedded in the circular holes 6; the fasteners 5 are provided with a mechanism to fasten the first mounting plate 3 and the second mounting plate 4 to the aluminum formwork. The telescopic mechanism 8 is used to install and fix the plate body 1; a damping mechanism 9 is provided at the top center of the first mounting plate 3 to adjust the two aluminum template bodies 1 at multiple angles. The user first opens the mounting groove 2 and the circular hole 6 on the two aluminum template bodies 1, then places the two buckles 7 into the circular hole 6 respectively, then places the first mounting plate 3 and the second mounting plate 4 into the mounting groove 2 respectively, and then tightens and fixes the first mounting plate 3 and the second mounting plate 4 to the aluminum template body 1 through the telescopic mechanism 8. Finally, the angle between the two aluminum template bodies 1 is adjusted through the damping mechanism 9.

[0027] like Figures 3 to 5As shown, the telescopic mechanism 8 includes: an internal hexagonal nut 10 rotatably connected to the inside of the fastener 5; a first rotating shaft 11 fixedly connected to the center of one end of the internal hexagonal nut 10; a first bevel gear 12 fixedly connected to the end of the first rotating shaft 11 away from the internal hexagonal nut 10; the first rotating shaft 11 rotatably connected to the fastener 5; a second bevel gear 13 meshing with one side of the first bevel gear 12; a rotating sleeve 14 fixedly connected to the side of the second bevel gear 13 away from the first bevel gear 12; and four rotating sleeves 14 rotatably connected to the fastener 5 respectively. Splined shafts 15 are slidably connected inside the rotating sleeve 14. One end of each splined shaft 15 passes through the second bevel gear 13 and extends into the interior of the fastener 5. The other end of each splined shaft 15 is fixedly connected to a first screw 16. The end of the first screw 16 away from the fastener 5 passes through the fastener 5 and extends to the movable block 17. The movable block 17 is fixedly connected to the first screw 16. Nuts 18 are fixedly connected to each fastener 5 near the first screw 16. The first screw 16 is threadedly connected to the nut 18. The user can rotate the Allen wrench to achieve this. The rotation of the angle nut 10 and the internal hex nut 10 drives the first rotating shaft 11, which in turn drives the first bevel gear 12, which in turn drives the second bevel gear 13, which in turn drives the rotating sleeve 14. The rotating sleeve 14 drives the spline shaft 15 to rotate. Simultaneously, the first screw 16 rotates and moves towards the fastener 5 through the engagement of the nut 18. The movement of the first screw 16 drives the moving block 17, which pushes the fastener 5. The fastener 5 drives the aluminum template body 1 through the circular hole 6, increasing the pressure between the aluminum template body 1 and the first mounting plate 3 and the second mounting plate 4. This increases the friction between the aluminum template body 1 and the first mounting plate 3 and the second mounting plate 4, achieving the purpose of splicing and fastening the corners of the two aluminum template bodies 1. Furthermore, when there is an error between the circular hole 6 and the fastener 5, the aluminum template body 1 can be properly installed and fixed to the first mounting plate 3 and the second mounting plate 4 by extending and retracting the first screw 16, improving practicality.

[0028] like Figure 3 As shown, rectangular structural members 19 are fixedly connected inside the buckle 7. Limiting blocks 20 are fixedly connected to both sides of the rectangular structural members 19 near the moving block 17. The limiting blocks 20 cooperate with the moving block 17. When the moving block 17 moves towards the fastener 5, the moving block 17 pushes the rectangular structural members 19 through the limiting blocks 20. The rectangular structure will drive the buckle 7. The buckle 7 drives the first mounting plate 3 and the second mounting plate 4 through the circular hole 6, which increases the friction between the buckle 7 and the first mounting plate 3 and the second mounting plate 4, and also increases the friction between the first mounting plate 3 and the second mounting plate 4 and the aluminum template body 1.

[0029] like Figure 2 and Figure 6 As shown, the damping mechanism 9 includes: a rotating plate 21 is provided on the top of the first mounting plate 3; a second screw 22 is provided at the center of the rotating plate 21; the bottom end of the second screw 22 is threadedly connected to the first mounting plate 3; an adjusting block 23 is fixedly connected to the top end of the second screw 22; first fixing blocks 24 are provided on both sides of the adjusting block 23; both first fixing blocks 24 are fixedly connected to the rotating plate 21; a third rotating shaft 25 is rotatably connected at the center of the two first fixing blocks 24; a second fixing block 26 is fixedly connected to one adjacent end of each of the two third rotating shafts 25; both second fixing blocks 26 are fixedly connected to the second mounting plate 4; and the third... Each of the three rotating shafts 25 has a circular fixing plate 27 fixedly connected to one end away from the second fixing block 26. When the user rotates one of the aluminum template bodies 1 horizontally, the aluminum template body 1 drives the second mounting plate 4. The second mounting plate 4 drives the rotating plate 21 through the first fixing block 24 and the second fixing block 26, so that the rotating plate 21 rotates around the first screw 16. The user can also rotate one of the aluminum template bodies 1 vertically, which drives the second mounting plate 4. The second mounting plate 4 drives the second fixing block 26, and the second fixing block 26 rotates inside the first fixing block 24 around the third rotating shaft 25.

[0030] like Figure 6 As shown, a first damping pad 28 is provided between the circular fixing plate 27 and the first fixing block 24. The first damping pad 28 is sleeved on the outer surface of the third rotating shaft 25, which increases the friction between the circular fixing plate 27 and the first fixing block 24, and thus increases the friction between the first fixing block 24 and the second fixing block 26.

[0031] like Figure 2 As shown, a second damping pad 29 is provided between the adjusting block 23 and the rotating plate 21. The second damping pad 29 is sleeved on the outer surface of the second screw 22, which increases the friction between the adjusting block 23 and the rotating plate 21, thereby increasing the friction between the rotating plate 21 and the first mounting plate 3. Furthermore, the user can adjust the friction by rotating the adjusting block 23 and the second screw 22.

[0032] like Figure 3 As shown, the fastener 7 has a slot 30 on the side near the fastener 5, which makes it convenient for the user to insert the first screw 16 and the limiting block 20 into the inside of the fastener 7.

[0033] Working principle: The user first makes mounting grooves 2 and circular holes 6 on the two aluminum template bodies 1. Then, the user places two fasteners 7 into the circular holes 6. Then, the user places the first mounting plate 3 and the second mounting plate 4 into the mounting grooves 2. At the same time, the user inserts the first screw 16 and the limiting block 20 into the fasteners 7 through the slot 30. The user rotates the hexagonal nut 10 with an Allen wrench. The rotation of the hexagonal nut 10 drives the first rotating shaft 11. The first rotating shaft 11 drives the first bevel gear 12. The first bevel gear 12 drives the second bevel gear 13. The second bevel gear 13 drives the rotating sleeve 14. The rotating sleeve 14 drives the spline. The splined shaft 15 rotates, and simultaneously the first screw 16 rotates. The first screw 16, through the engagement of the nut 18, moves towards one side of the fastener 5. This movement of the first screw 16 drives the moving block 17, which in turn pushes the fastener 5. The fastener 5, through the circular hole 6, drives the aluminum template body 1, increasing the pressure between the aluminum template body 1 and the first mounting plate 3 and the second mounting plate 4. This increases the friction between the aluminum template body 1 and the first and second mounting plates 3 and 4, achieving the purpose of splicing and fastening the corners of the two aluminum template bodies 1. Furthermore, this is achieved when there is an error between the circular hole 6 and the fastener 5. At the same time, the aluminum formwork body 1 can be properly installed and fixed to the first mounting plate 3 and the second mounting plate 4 by means of the extension and retraction of the first screw 16, which improves practicality. It can be used to firmly splice the two aluminum formworks at the corner, and the spliced ​​aluminum formwork can be freely adjusted at the angle between the two aluminum formworks according to the construction requirements, which improves practicality and solves the problem that when using aluminum formwork at the corner of a building, the splice of the two aluminum formworks is generally welded by argon arc welding. However, since the two aluminum formworks cannot be freely adjusted according to the angle of the corner after welding, and disassembly requires a cutting device to cut the weld. The problem of easy damage to the aluminum template and poor practicality caused by cutting is addressed by the user. After the two aluminum template bodies 1 are fastened together, the user can rotate one of the aluminum template bodies 1 horizontally. The aluminum template body 1 drives the second mounting plate 4. The second mounting plate 4 drives the rotating plate 21 through the first fixing block 24 and the second fixing block 26, so that the rotating plate 21 rotates around the first screw 16. The user can also rotate one of the aluminum template bodies 1 vertically. The aluminum template body 1 drives the second mounting plate 4. The second mounting plate 4 drives the second fixing block 26. The second fixing block 26 rotates inside the first fixing block 24 around the third rotating shaft 25.
