CONSTRUCTION TECHNOLOGY FOR ZIGZAG FASTENING OF MULTIPLATE LAYERS OF STEEL BARS OF CONCRETE BEAM AND STEEL COLUMN
At present,steel structure buildings are widely applied,but concrete structures are often adopted for basements.Transition members are required on the basement layer,involving the connection between longitudinal steel bars of beams and rigid steel columns.Design drawings and construction drawings only show the connection of one layer of steel bars on and under concrete beams with rigid steel columns.However,complex connections of two or more layers of steel bars and rigid steel columns are involved in the actual construction.In the conventional construction process,long and short connecting plates are lap welded with steel bars,which may cause collision between longitudinal bars of columns and lap plates,between column stirrups and steel bracket webs and between vertical bars of walls and lap plates,and greatly increase difficulties in construction on site.A new process of zigzag fastening of sleeves and connecting plates is studied independently,to solve the problems in connection between multiple layers of longitudinal bars on and under beams and rigid steel columns,avoid collision between bars and connecting plates,and reduce the construction quantity and difficulty on site.This is of important significance for the construction progress.
