Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a convenient aluminum-wood combined formwork assembly and quick fixing device. Background Technology

[0002] Aluminum-wood composite formwork uses aluminum alloy as the structural frame, leveraging its lightweight, sturdy, corrosion-resistant, and easy-to-process properties to provide a stable support structure for the formwork, ensuring it can withstand significant pressure without deformation during concrete pouring. Wood is used as the surface material, taking advantage of its excellent plasticity, affinity with concrete, and high surface smoothness, resulting in a smooth and even concrete surface after pouring, achieving high quality standards and reducing the need for subsequent plastering and other processes.

[0003] Existing aluminum-wood composite formwork splicing and fixing devices resemble a duckbill structure. The aluminum plate and wooden board are clamped in the middle of the duckbill, and then a nut is rotated to move the lower part of the duckbill upwards, thus completing the splicing and fixing of the aluminum plate and wooden board. During use, whether installing or disassembling, this splicing and fixing device requires tightening the nut. Therefore, when the working area is large, the large amount of work involved in tightening the nut leads to low efficiency in splicing and disassembling aluminum-wood composite formwork.

A wedge block is provided below the rotating shaft. The wedge block is fixed to the clamp plate. The top surface of the wedge block is an inclined surface that contacts the eccentric wheel. The rotating shaft has a hollow structure with a pressing column inserted inside. A clutch plate is fixed to the ends of the two pressing columns that are close to each other. A spring II is clamped between the two clutch plates. The clutch plates are circumferentially fixed and axially slidingly connected to the guide rod. A ring of locking teeth is provided on the end face of any clutch plate away from the spring II. The locking teeth have ratchet teeth that mesh with them. The ratchet teeth are located at the end of the rotating shaft near the clutch plates. A pressing mark is provided on the pressing column near the locking teeth.

[0006] An anti-slip pad is provided on the upper surface of the base.

[0017] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0018] Please see Figures 1-5 A convenient aluminum-wood combined template assembly and quick fixing device is provided, which has a base 1, a guide rod 2 is fixedly connected to the rear side of the upper surface of the base 1, and a clamping plate 3 is provided on the guide rod 2 and slidably connected thereto. The clamping plate 3 is parallel to the base 1, and the two form a duckbill structure.

[0019] The clamping plate 3 is supported on both sides by springs I10, which are located between the clamping plate 3 and the base 1. A pull handle 8 is provided above the clamping plate 3. The pull handle 8 is connected to the guide rod 2 via two side arms 17 that are perpendicularly fixed to its left and right ends. Each side arm 17 is connected to the guide rod 2 via a rotating shaft 5. An eccentric wheel 7 is fixed to the side of the rotating shaft 5 away from the side arm 17. A wedge block 4 is provided below the rotating shaft 5 and is fixed to the clamping plate 3. The top surface of the wedge block 4 is an inclined surface that contacts the eccentric wheel 7. The rotating shaft 5 has a hollow structure with a pressing post 15 inserted inside. A clutch plate 12 is fixedly connected to the ends of the two pressing posts 15 that are close to each other. A spring II 13 is clamped between the two clutch plates 12. The clutch plates 12 are circumferentially fixed and axially slidingly connected to the guide rod 2. A ring of locking teeth 14 is provided on the end face of any clutch plate 12 away from the spring II 13. The locking teeth 14 are provided with ratchet teeth 16 that mesh with them. The ratchet teeth 16 are located at the end of the rotating shaft 5 near the clutch plates 12. A pressing mark is provided on the pressing post 15 near the locking teeth 14.

[0020] The more preferred solution in this embodiment is as follows:

[0021] An anti-slip pad 9 is provided on the upper surface of the base 1 to facilitate better splicing and fixing of the aluminum plate and wooden board by the duckbill structure, thereby improving stability.

[0022] The rotating shaft 5 is connected to the guide rod 2 via the bearing 6, allowing for flexible rotation, saving effort, and featuring a simple, safe, and reliable structure.

[0023] The guide rod 2 is provided with a guide groove 11, and the clamping plate 3 is provided with a slider that is adapted to the guide groove 11. The guide groove can limit the clamping plate and improve the stability of the clamping plate movement.

[0024] The cross-section of the guide rod 2 is rectangular, so the clamping plate does not need to be equipped with an anti-rotation structure, thus making the device simple and reliable.

[0025] The working principle of this utility model:

[0026] In use, the staff first attaches the aluminum plate and the wooden board together, then clamps the base 1 on one side of the aluminum plate and the wooden board, and then pulls the handle 8 towards the guide rod 2. Pulling the handle 8 causes the rotating shaft 5 to rotate counterclockwise, and the rotating shaft 5 causes the eccentric wheel 7 to rotate. During the rotation, the eccentric wheel 7 presses the wedge block 4, the clamping plate 3 descends, the duckbill structure closes tightly, and the spring I 10 is compressed, thus completing the clamping and fixing of the aluminum plate and the wooden board by the duckbill structure.

[0027] During the process of rotating the shaft 5 by pulling the handle 8, the inclined surface of the ratchet 16 on the shaft 5 contacts the inclined surface of the locking tooth 14. When the handle 8 is stopped and the shaft 8 stops rotating, the straight surface of the ratchet 16 contacts the straight surface of the locking tooth 14, thereby preventing the handle 8 from resetting and maintaining the clamped and fixed state.

[0028] When the device needs to be disassembled, press the pressing pin 15 marked with a pressing symbol to disengage the locking tooth 14 from the ratchet tooth 16, release the rotating shaft 5 and the eccentric wheel 7, and the spring I 10 will automatically reset under the action of elastic force, pushing the clamping plate 3 to rise, opening the duckbill structure, and the wedge block 4 will drive the rotating shaft 5 to rotate clockwise. The rotating shaft 5 will drive the pull handle 8 to reset, and the device can then be disassembled in preparation for the next use.

[0029] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the protection scope of the present invention.
