The utility model relates to the technical field of steel reinforcement cage, concretely to the whole structure of variable
diameter steel reinforcement cage, including concrete
cushion layer, be provided with
screw thread reinforcement in concrete
cushion layer, the bottom plate body is provided with
screw thread reinforcement above concrete
cushion layer, the anchor is connected with the
screw thread reinforcement upper end, be provided with spiral
stirrup between anchor and bottom plate body, be provided with multiple groups of bent reinforcement on bottom plate body, the stretchable part is provided with screw thread reinforcement below concrete cushion layer, the utility model, screw thread reinforcement, bottom plate body, bent reinforcement and spiral
stirrup etc. jointly constitute the stable steel reinforcement cage structure, screw thread reinforcement as main force component, bear the tension and pressure, bottom plate
body positioning and supporting split
type variable diameter steel reinforcement cage, ensure its correct position in concrete member, bent reinforcement resists
shear force, strengthens the
structural integrity, spiral
stirrup restricts concrete, improves its
compressive strength and deformation capacity, makes the structure more stable, can better bear various loads.
