Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, in particular to an adjustable main rib used under a beam. Background Art

[0002] The specifications of socket-type disc-locked steel pipe scaffolding on the market include base, vertical poles, cross bars, diagonal bars, top supports, long top supports, double support beams, and reinforced cross bars.

[0003] When used with long top supports, double supporting beams can be placed on the discs of the long top supports on both sides of the beam to serve as the main ribs under the beam. When the spacing between the uprights on both sides of the beam is 900mm or 1200mm, a 1350mm double supporting beam is used; when the spacing between the uprights on both sides of the beam is 1500mm, a 1650mm double supporting beam is used. When the spacing between the uprights on both sides of the beam is 900mm, one bolt needs to be removed and the bolt needs to be restored after the double supporting beam is installed, which affects the construction efficiency. The 1650mm supporting beam is not used frequently in practice and is mostly left in the warehouse, which is a waste of resources. In addition, the double supporting beam cannot be used for 48 system buckles and 60 system buckles.

[0004] When used with long top supports, reinforcing cross bars can also be connected to the discs of the long top supports on both sides of the beam to act as the main ribs under the beam. When the spacing between the uprights on both sides of the beam is 900mm, a 900mm reinforcing cross bar is used; when the spacing between the uprights on both sides of the beam is 1200mm, a 1200mm reinforcing cross bar is used; when the spacing between the uprights on both sides of the beam is 1500mm, a 1500mm reinforcing cross bar is used. In summary, the reinforcing cross bars need to be matched one by one and are not very flexible.

[0005] To solve the above problems, we proposed an adjustable main rib under the beam. Utility Model Content
