Startabox Continuity System




The concept and use of reinforcement continuity strip systems or ‘pull-out bar’ systems has been widespread in Europe and further for the last 30 years and is widely accepted means of providing reinforcement continuity across construction joints in concrete. The system utilises the concept of overlapping reinforcement to provide a connection.

The Startabox Continuity System consists of specially selected, high yield reinforcing steel, housed in a fully perforated and hot dip galvanised carrier unit. The unit ends are sealed to prevent the ingress of concrete. The reinforcement used is CARES approved and cut and bent to conform to BS8666. The system is assembled in a BS EN ISO 9001 factory environment and the full system carries a CARES Technical Approval.

The units are used on site by nailing to formwork, prior to a concrete pour. Alternatively, units can be wire tied to the main reinforcement arrangement. After concrete is poured and the formwork then struck, the lid is removed to provide the connection or overlap bars. The bars are bent out of the case to provide an overlap connection to the main reinforcing steel and next concrete pour. The case design offers an efficient key and rebate and requires no further joint preparation. The perforated casing ensures that the product remains embedded in the structure when striking the formwork and the concrete and case become a composite material. The case remains in the joint and is filled with concrete on the subsequent concrete pour.
