Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a height adjustment device for aluminum formwork. Background Technology

[0002] Aluminum formwork, also known as aluminum alloy formwork, is a building formwork made of aluminum alloy. It is a new generation of formwork system that emerged after wooden and steel formwork. The application of aluminum formwork systems in the construction industry has improved the construction efficiency of building construction projects. In the application of aluminum formwork, it is necessary to install the aluminum formwork to the appropriate height as needed. Currently, the height adjustment of aluminum formwork is generally achieved by using adjustable brackets. However, this direct height adjustment is achieved by inserting screws into holes of different heights, which is very inconvenient and cannot be adjusted quickly.

[0003] To address the aforementioned issues, existing technology CN213115634U proposes an aluminum template height adjustment structure. This structure allows for height adjustment of the aluminum template simply by rotating a crank handle, simplifying operation and making it convenient to use.

[0004] However, the above-mentioned structure provides support from bottom to top, which can only adjust the height of aluminum formwork at higher positions, but cannot be applied to aluminum formwork at lower positions. For adjusting the height of aluminum formwork at lower positions, the existing method is to use shims, which requires the use of suitable shims and to insert the shims into the bottom of the aluminum formwork. This adjustment method is very cumbersome. In order to address the above problems, we provide an aluminum formwork height adjustment device to solve the aforementioned issues. Utility Model Content

[0028] The lifting block 12 is fixedly connected to a lifting plate 7 at the position where it extends out of the vertical sliding groove 2. A central rotating column 6 is fixedly connected in the middle of the lifting plate 7. A support rod 4 is rotatably connected to the central rotating column 6. An aluminum template adjustment frame 3 is fixedly connected to the end of the support rod 4 away from the central rotating column 6. The aluminum template adjustment frame 3 has several mounting holes. In use, the height of the aluminum template support can be directly adjusted through the aluminum template adjustment frame 3. Alternatively, bolts can be used to connect the mounting holes to the holes on the aluminum template before height adjustment, making it flexible and convenient to use.

[0029] The support rod 4 is equipped with a locking assembly for locking its position. The locking assembly includes a locking hole 20 and a threaded hole 22. The locking hole 20 is located at both ends of the lifting plate 7, and the threaded hole 22 is located on the support rod 4 near the position corresponding to the locking hole 20. A locking screw 21 is threaded into the threaded hole 22, and a handle 5 is fixedly connected to the end of the locking screw 21 away from the locking hole 20. The end of the locking screw 21 near the threaded hole 22 has a smooth section. When it is necessary to adjust the aluminum template at a higher position, first rotate the locking screw 21 to pull it out of the locking hole 20, then flip the support rod 4 to a position above the central rotating column 6, and after flipping, rotate the locking screw 21 to insert it into the locking hole 20. When it is necessary to adjust the aluminum template at a lower position, flip the support rod 4 to a position below the central rotating column 6 for locking.

[0030] The lifting assembly includes a threaded rod 11, which is rotatably connected inside the hollow square rod 1. A bottom rotating rod 13 is fixedly connected to the lower end of the threaded rod 11. The threaded rod 11 is threadedly connected to the lifting block 12. A driving assembly for driving the threaded rod 11 to rotate is provided on one side of the hollow square rod 1. The driving assembly includes a second bevel gear 15, which is fixedly connected to the upper end of the bottom rotating rod 13. A first bevel gear 14 is rotatably connected to one side of the hollow square rod 1. The first bevel gear 14 meshes with the second bevel gear 15. A rotating handle 9 is installed at the position where the connecting shaft of the first bevel gear 14 passes through the hollow square rod 1. When it is necessary to raise or lower the lifting block 12, rotating the rotating handle 9 drives the first bevel gear 14 to rotate. The rotation of the first bevel gear 14 drives the second bevel gear 15 to rotate. The rotation of the second bevel gear 15 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 can drive the lifting block 12 to adjust its height.

[0031] The hollow square rod 1 has a pressing assembly at its bottom for pressing the bottom rotating rod 13.

The side of the frustum opposite to the friction disk 19 is a rough surface. The top pressing block 18 can be pushed to press against the friction disk 19 by the spring 17. The friction force is used to limit the friction disk 19 and prevent the threaded rod 11 from rotating at will. When adjusting the height of the lifting block 12, the foot pedal 10 can be stepped on to move downward, so that the top pressing block 18 and the friction disk 19 are separated. After separation, the height of the lifting block 12 can be adjusted by rotating the handle 9.

[0032] The working principle of this utility model is as follows: When in use, the position of the support rod 4 is first adjusted according to the usage situation. When it is necessary to adjust the aluminum template at a high position, first rotate the locking screw 21 to pull the locking screw 21 out of the locking hole 20, and then flip the support rod 4 to the position above the central rotating column 6. After flipping, rotate the locking screw 21 to insert it into the locking hole 20. When it is necessary to support the aluminum template at a low position, flip the support rod 4 to the position below the central rotating column 6 to lock it. When adjusting the height, first step on the foot pedal 10 to move it downward, so that the top pressure block 18 is separated from the friction plate 19. Then rotate the rotating handle 9 to drive the first bevel gear 14 to rotate. The rotation of the first bevel gear 14 drives the second bevel gear 15 to rotate. The rotation of the second bevel gear 15 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 can drive the lifting block 12 to adjust the height.
