Concrete structure and method of making it

摘要

A novel and simple method of making a novel concrete slab structure supported on vertical columns (1) and having high strength against punching shear failure involves: placing stirrup cages (3, 3') with their open sides downwards directly on top of the bottom reinforcement net (7) in a form; laying, crossed bent bars (8) over the top of the column and running along the bottom reinforcement net (7); laying a top reinforcement net (7') on top of the stirrup cages (3,3') and the crossed bent bars (8); pouring concrete into the form to a level above the top reinforcement net (7').
