Because the hanging steel frame 2 is only provided with the hanging frame 21, the hanging frame 21 is in a hanging mode, the structure of the hanging frame is unstable and easy to shake, and the load carried by the operation in the construction process also causes structural instability, so that the stabilizer bars 213 are arranged on two sides of the hanging frame unit in order to ensure the structural stability of the hanging frame 21, the stabilizer bars 213 are fixedly arranged at two ends of the shape-following keels 211, the stabilizer bars 213 are connected with a building structure, and then the drawknot which is stable for the hanging frame unit is fixed on the building structure, so that the holding state of the hanging frame unit is stable, the shaking of the hanging frame unit in the construction process is avoided, and the holding state of the hanging frame 21 is stable and the structure is safe.
As shown in fig. 6, further, the hanger unit includes a conformal keel 211 and a connecting hanger bar 212, the conformal keel 211 is horizontally arranged and correspondingly arranged outside the building structure layer, the inner side of the scaffold structure 3 is erected on the floor board between the building structure layers, the outer side of the scaffold structure is erected on the conformal keel 211, so that the scaffold structure 3 is horizontally erected, the connecting hanger bars 212 are vertically arranged on the conformal keel 211 at intervals, hanging of the conformal keel 211 is realized, and the connecting hanger bar 212 is used for connecting the conformal keel 211 with the overhanging steel beam frame 1 and connecting the conformal keel 211 of the adjacent hanger unit.

As shown in fig. 5, further, the tie bar 221 further includes an upper tie bar connected to the bottom end of the hanger 21 through the connecting boom 212, and a lower tie bar connected to the upper tie bar through the connecting boom 212.
According to the concrete structure of the tie frame 22 arranged on the building layer height or the building structure, when the layer height of the bottom layer is higher, two tie rods of an upper tie rod and a lower tie rod are arranged together to strengthen the structural stability, wherein the upper tie rod plays a role of strengthening the stability of the tie frame 22 by shortening the length of the connecting suspender 212 in the tie frame 22 so as to promote the stability of the tie, when the layer height of the bottom layer is lower, the length of the connecting suspender 212 in the tie frame 22 is also shorter, the tie requirement can be met by only arranging the lower tie rod, and the integral structure has enough stability at the moment by connecting the connecting suspender 212 with the hanging frame unit at the lowest side.
The drawknot frame 22 can not only promote the stability of the hanging frame 21, but also can not influence the passing of personnel and materials below. Compared with the traditional full-hall scaffold, the drawknot frame 22 only plays a drawknot role, but does not play a supporting role, so that the frame structure with larger space is adopted, and the drawknot role is realized, and meanwhile, the lower personnel and material transportation cannot be influenced. In addition, since the tie frame 22 only needs to provide tension, the tie frame can be arranged on the ground, and can also be arranged on a roof, a terrace or a hall of a bottom building, so that the requirement of tie is met.

Because hang steelframe 2 is through connecting jib 212 lug connection on the outer end of crossbeam, in the work progress, can have the uneven condition of load distribution, when load passes through connecting jib 212 and conveys on the crossbeam, different loads can lead to there being certain difference in height between the outer end of different crossbeams, and connect the length unanimous of jib 212, therefore if there is the difference in height of crossbeam, can lead to hanging steelframe 2 in the condition that the stress concentration appears, even lead to overall structure to take place to warp, and then lead to hanging steelframe 2's overall stability not enough, there is certain potential safety hazard. In order to ensure that the structure of the hanging steel frame 2 cannot deform due to the height difference of the cross beams above the hanging steel frame, the ring beams 12 are arranged at the outer ends of the cross beams, so that all the cross beams are connected into a whole, further, the height difference among the cross beams is not ensured, the integral structure of the hanging steel frame 2 cannot be influenced, the structural safety is improved, meanwhile, due to the special-shaped structure of the outer vertical surface of a building, the cross beams cannot extend out of the curved surface, and the ring beams 12 are used as hanging points, so that hanging connection at special points is realized.
