Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a multi-purpose scaffolding upright fixing device. Background Art

[0002] Scaffolding is widely used in the field of construction. It includes fastener-type steel pipe scaffolding, disc-type steel pipe scaffolding, etc., and its functions include protective external scaffolding, formwork support, etc. When the formwork support poles are set within the post-casting zone and the floor opening, or when the external scaffolding adopts a cantilever frame, an I-beam must be set as the basis of the scaffolding poles, so the fixation of the scaffolding poles on the steel beams becomes a problem that must be solved.

[0003] According to the traditional process, the pole is usually welded to the steel beam, or a short steel bar is welded on the steel beam and the pole is inserted into the steel bar for fixing. The above methods require welding operations, which are complicated to operate and will cause a certain degree of damage to the steel beam components; and the fixing method is a one-time implementation. If the position of the pole is changed, the original welding point must be cut off and re-welded, resulting in a waste of labor and materials; at the same time, this method can only solve the positioning of the pole, but cannot solve the problem of adjusting the elevation of the pole.
