Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cantilevered scaffolding, and particularly relates to a detachable under-bracing I-beam cantilevered scaffolding device. BACKGROUND

[0002] At present, in the construction industry, I-beam cantilevered scaffolding is extremely widely used. In particular, in the construction process of some medium and high-rise buildings, I-beam cantilevered scaffolding with a height of more than 20 meters is often needed to be erected. The traditional method usually requires that a steel plate is pre-buried in a wall body or a beam body in advance, and then the under-bracing rod member is fixedly connected with the main beam through welding. However, this method not only easily causes damage to the main beam structure and has a large safety hazard, but also has a high requirement on the positioning accuracy of the pre-buried steel plate and the welding process level.

[0003] In addition, the installation and removal process of the under-bracing rod member of the cantilevered beam is complicated and time-consuming, which brings great inconvenience to the construction. If only a bolt is used for simple fixation, when the stress is too large, the bolt connection position is easy to loosen or even displace, which greatly reduces the supporting effect. Once the under-bracing rod member is displaced, the supporting system of the entire scaffolding will be seriously affected, and there is a risk of collapse at any time. More seriously, this safety hazard is often difficult to be detected in time, and it is also impossible to give timely and effective warning to the on-site construction personnel, thereby further aggravating the safety risk.

[0004] Therefore, it is of great significance to study a new detachable under-bracing I-beam cantilevered scaffolding device to solve the above problems. SUMMARY

In addition, the installation and removal process of the under-bracing rod member of the cantilever beam is complicated and time-consuming, which brings great inconvenience to the construction. If only simple fixing is adopted by using bolts, the bolt connection position is prone to looseness or even displacement when the stress is too large.
