Ring-beam reinforcing connection structure and ring-beam construction method

Abstract

The invention relates to a ring-beam reinforcing connection structure and a ring-beam construction method. The ring-beam reinforcing connection structure comprises a ring-beam reinforcing cage, beam column reinforcing ribs and floor reinforcing ribs. The ring-beam reinforcing cage comprises an inner ring beam, an outer ring beam, annular beams and longitudinal beam ribs, and the ring-beam beams and the longitudinal beam ribs are different in diameter and are arranged between the inner ring beam and the outer ring beam. The longitudinal beam ribs are connected with the inner ring beam, the outer ring beam and the annular beams in an enclosed manner to form an annular cylindrical structure. The beam column reinforcing ribs are penetratingly arranged in the cavity of the ring-beam reinforcing cage and connected with the same. The floor reinforcing ribs include first beam reinforcing ribs and second beam reinforcing ribs, the first reinforcing ribs penetrate the ring-beam reinforcing cage and are connected with the same, the second beam reinforcing ribs are penetratingly arranged in the ring-beam reinforcing cage, the ends of the second beam reinforcing ribs are located inside the ring-beam reinforcing cage and are connected with the same. By the adoption of the ring-beam reinforcing cage, the problem about buckling deformation produced in construction of ring beams is solved, and connection strength between beam columns and floors can be guaranteed.

Description

technical field [0001] The invention relates to the field of construction, in particular to a ring beam steel bar connection structure and a ring beam construction method. Background technique [0002] In building structural engineering, the connection between beams and columns and floors usually adopts the steel pipe column ring beam construction method, that is, ring beams are set on the steel pipe columns, joint construction is carried out according to the design shape and size, and the main bars of the surrounding beams are welded to the steel pipe. On the ring plate of the column ring beam, the ring steel bars with gradually increasing diameter are processed around the steel pipe column on the upper and lower ring plates of the steel pipe column ring beam, and the mechanical connection or welding is carried out to seal. [0003] This construction method has high requirements on the machining accuracy of the large-diameter annular steel bar surrounding the steel pipe col...
