Abstract
The utility model discloses a well type frame beam strengthened flat slab connecting structure which comprises a flat slab and a concrete column which are formed in a one-piece casting mode. A well type frame beam is arranged at the position of the connection node between the flat slab and the concrete column. The well type frame comprises two horizontal stud strengthening bars and two longitudinal stud strengthening bars. The two horizontal stud strengthening bars are perpendicular to the two longitudinal stud strengthening bars, and the two horizontal stud strengthening bars and the two longitudinal stud strengthening bars both comprise rectangular beams and a plurality of studs. The plurality of studs are all welded on the upper surfaces of the rectangular beams. After the flat slab and the concrete column are casted in a one-piece mode, the well type frame beam is hidden in the flat slab. The well type frame beam strengthened flat slab connecting structure has the advantages of being large in connecting stiffness, good in anti-punching ability and beneficial for form bracing during node processing and construction.
