technical field

The utility model relates to a cantilevered load-bearing frame, in particular to a flower-basket type cantilevered load-bearing frame, which belongs to the technical field of scaffolding construction.

Background technique

The new scaffolding construction technology in civil engineering is a key point in the construction project, while the traditional cantilevered steel beam must pass through the outer wall of the building, extend into the room and lay on the main structure floor, and then use 3 U Type embedded parts are anchored on floor slabs and floor beams.

However, for the traditional construction method, the layout of the steel beams protruding into the room is complicated, which hinders the cleaning of indoor construction waste and the walking of construction workers. Before the steel beam, it may be necessary to cut the U-shaped anchor ring on site. After removal, it is necessary to fill the hole and subsidize the bricks, which increases the construction time; 1.25 times, so a lot of steel is invested at one time, and the weight is heavy. The installation and removal of a 3 to 5-meter I-beam needs to rely on the tower crane throughout the whole process. There are many blind spots in the lifting process, and there are great safety hazards. The labor input is large; In addition, if the layout of the traditional cantilevered I-beam happens to collide with the position of the stairs, the I-beam lying in the stairway will affect the workers' walking up and down. If you are not careful, a head-on collision is most likely to occur here.
