[0002] In existing life, the temporary auxiliary support device for a cantilever beam is a special device used for temporarily supporting a cantilever beam in building construction. A cantilever beam refers to a beam that extends outside the main structure in a building. They require additional support during construction to ensure safety and structural stability. The design of the temporary support device needs to consider various factors, including the length, weight, load during construction, position of the support point, etc. High-strength materials such as steel are required during manufacturing, and it is necessary to ensure that all components are firmly connected.

Temporary support frames are often used for the cantilever construction of the exterior wall or roof ceiling of a building to support and protect the safety of workers. The size of the cantilever beam will be adjusted according to the building. The auxiliary support device cannot support cantilever beams of different sizes, resulting in a limited scope of application and certain limitations, reducing the practicability of the temporary auxiliary support device for a cantilever beam.

[0031] In summary: When using this device, first, when it is necessary to move the moving shell 3 inside the fixing frame 4, rotate the nut 71 to move it out from the outer surface of the screw rod 74. At this time, move the limiting plate 72 out from the outer surface of the straight groove 10. Pulling the rotating disc 73 can drive the shaft rod 75 and the screw rod 74 to move. The screw rod 74 drives the engaging block 14 and the second rack 15 to move. The second rack 15 moves out from the inner wall of the first rack 9, and the engaging block 14 moves from the inner side of the inner wall of the moving shell 3 to the inside of the moving shell 3. At this time, the clamping plate 2 can be pulled to drive the moving shell 3 to move. The moving shell 3 slides inside the fixing frame 4. When adjusted to the appropriate height, when the second rack 15 is re-engaged with the tooth surface of the first rack 9, then place the limiting plate 72 on the outer surface of the screw rod 74 and closely fit it with the outer surface of the straight groove 10. Then tighten the nut 71, and one end of the nut 71 abuts against the side surface of the limiting plate 72, so that the second rack 15 is stably engaged with the first rack 9 to prevent it from falling off. When it is necessary to adjust the lifting of the cantilever beam body 1, use a wrench to drive the rotating ring 62 to rotate. The rotating ring 62 drives the connecting ring 63 installed at the bottom to rotate inside the ring groove 69. The threaded groove 61 formed inside the rotating ring 62 drives the threaded rod 64 threadedly connected to the inner wall to lift and lower. The threaded rod 64 moves out from the inside of the sleeve rod 67 for lifting and lowering. The threaded rod 64 drives the top plate 68 connected to the top to move. The top plate 68 drives the cantilever beam body 1 installed at the top to lift and lower.
