Description

Cantilever frame system
Technical Field
The invention belongs to the technical field of building construction, and particularly relates to an overhanging frame system.
Background
In the construction process of building engineering, in order to set up a scaffold on the outer side of a building, a large number of I-steel beams are required to be arranged on an outer wall to serve as set up supports. However, the existing cantilever frame system using I-steel as a main component has a plurality of problems. When most of the I-steel is arranged on the outer wall of the building, the I-steel penetrates through the outer wall, the part of the I-steel in the room is fixed on the floor, and the extending part is used as a support of the scaffold, so that potential safety hazards are caused by the damage of the outer wall of the building, and a large amount of steel is wasted. Many detachments of the I-steel are destructive and cannot be completely recycled. The upper pull rod is used for providing a rear upper pull force for the I-steel, no other auxiliary supporting force system exists when the upper pull rod fails, the upper end of the upper pull rod also has a larger outward component force on a wall body, and the upper pull rod is fixed at one side of the I-steel instead of the middle of the I-steel due to the existence of the scaffold, so that the tension force can have a torsion force on the I-steel, the I-steel is stressed in an unbalanced manner, and the whole cantilever system is not stable and reliable enough. The rust-proof mode of the cantilever frame system is generally spraying paint, if the paint falls off, the rust-proof effect cannot be achieved, the rust-proof treatment cannot be immediately carried out on a construction site, and potential safety hazards exist. When installing the scaffold, only one I-steel is used as a supporting point, so that the scaffold has certain shaking and potential safety hazard. The existing cantilever frame system is also insufficient in shock resistance and lightning protection capability.
