The utility model provides an overlapped prefabricated balcony with a flower
bed, which comprises a
peripheral flower
bed arranged on the prefabricated balcony, and the prefabricated balcony comprises a bottom plate, a
cantilever beam surface rib, two side enclosing walls and a
peripheral enclosing wall, the bottom plate and the enclosing walls are integrally arranged,
floor slab bottom ribs are exposed inwards from the bottom plate,
floor slab surface ribs which extend inwards from the
peripheral enclosing walls and are distributed in parallel at intervals and
floor slab distribution steel bars which extend inwards from the enclosing walls on the two sides and are distributed in parallel at intervals are arranged on the upper portion of the bottom plate, and the floor slab surface ribs and the floor slab distribution steel bars are vertically staggered to form nodes; the form that the beams and the slabs are stressed together is adopted, the
diameter of the beam steel bars is reduced, the process and stress requirements are met, the requirement for
assembly type node connection is met, the balcony floor slab surface ribs are connected with the surface steel bars of the inner-span composite floor slab, and stress of the
cantilever slab is guaranteed; in addition to in-plate nodes, beam-wall nodes and beam-beam nodes are designed, so that balcony
cantilever beam surface ribs are connected with an inner-span wall or a superposed precast beam, and the stress of the cantilever beam is ensured.
