The utility model discloses an overhanging structure for a
bay window of a building, which belongs to the technical field of
bay window overhanging, comprises a
bay window component, and is characterized in that an upper hanging component and a lower supporting component are arranged, so that the bay window component can be hung on the bay window; the mode that a traditional
cantilever structure purely depends on a
cantilever beam or plate to extend outwards from a building body to support a bay window is changed, bay window
load distribution is more uniform, too large
bending moment is prevented from being generated at the
cantilever root, the large section size and the reinforcement quantity needed by the position for resisting the
bending moment are reduced, the material cost and the structure
self weight are reduced to a certain degree, and the construction efficiency is improved. Meanwhile, by means of the up-and-down cooperative supporting and hanging mode, better performance can be achieved in the aspect of resisting upsetting moment caused by lateral force generated by strong wind or earthquakes, the
structural stability is enhanced, and compared with traditional cantilever structure construction, the structure does not need to be like a traditional cantilever structure.
