The invention provides a
scaffold supporting structure and
system, and relates to the field of building tools. The
scaffold supporting structure comprises a first inclined supporting part, a second inclined supporting part and a lifting
assembly, a support allowing a
scaffold to be mounted is arranged on the first inclined supporting part, the first end of the first inclined supporting part is in
pivot joint with the first end of the second inclined supporting part, a first clamping part is arranged at the first end of the lifting
assembly, a second clamping part is arranged at the second end of the lifting
assembly, the second end of the first inclined supporting part is in
pivot joint with the first clamping part, and the second end of the second inclined supporting part in
pivot joint with the second clamping part; and the lifting assembly drives the first clamping part and the second clamping part to move, so that the first clamping part is clamped on an upper layer edge beam, and the second clamping part is clamped on a lower layer edge seam. The scaffold supporting structure is rapid, easy and convenient to
mount and demount, work such as reserving, pre-burying, hole opening and filling, steel
wire rope oblique-pulling and
open fire welding is omitted, and the overall erecting time of the cantilevered scaffold is saved.
