Description

Technical Field

[0001] The utility model relates to building construction auxiliary equipment, in particular to a convenient erection and dismantling auxiliary device for a steel pipe scaffold, which is especially suitable for erection and dismantling of scaffolding projects in the field of construction. Background Art

[0002] During the construction of scaffolding projects, the difficulty of erection and the high risk of high-altitude operations have been listed as key control sources of danger for the project. Its operators need to be trained and assessed by professional institutions and hold special operation certificates before they can take up their posts.

[0003] At present, the steel pipes used to erect steel pipe scaffolding are generally 48mm in diameter, with a wall thickness of 2.7mm to 3.5mm. The vertical poles used for erection are generally 6m long and weigh about 30kg. Due to the linear structure of the steel pipe, the scaffolder holds the horizontal steel pipe in the middle of the work area with both hands and lifts it up, rotates it 90 degrees and stands it upright. Generally, the steel pipe is moved up by clever force until the part near the lower end is held with both hands, and then it is overlapped on the installed vertical pole. The installation process is difficult, slow and dangerous in high-altitude operations.

[0004] Therefore, a structure for assisting the erection of steel pipes is needed to reduce the construction difficulty, increase the construction speed and improve the safety. Utility Model Content

This auxiliary device can help avoid the above problems.

[0018] 2. Set up U-shaped clamps to ensure that the use requirements are met while improving assembly and disassembly efficiency.

[0019] 3. Two U-shaped clamps are set on both the rotating rod and the fixed rod to ensure a more reliable connection between the auxiliary device and the steel pipe, ensuring safety during operation.
