ARBOX® Joint Reinforcement is a ready-to-install system for creating stiff concrete casting joints of reinforced concrete elements. ARBOX® can be attached to formwork without having to penetrate or make other adjustments to the formwork. ARBOX® Joint Reinforcement is suitable for creating a wide range of connections, such as wall-to-wall, column-to-wall, and wall-to-slab.
The pre-bended rebars of ARBOX® are hidden in a galvanized steel box and can be straightened when needed. This system increases safety on the construction site and enables fast construction of connections in both cast-in-situ and precast structures.
ARBOX® is designed according to Eurocode. It enables longitudinal and transverse tensile forces and shear forces to be transfered to the joint. Shear resistance transverse to the joint can be increased significantly by combining ARBOX® with shear reinforcement made with PSB® Punching Reinforcement System.
Based on the required resistance and dimensions, the suitable ARBOX® model can be selected using the tables in the ARBOX® Joint Reinforcement Technical Manual. ARBOX® is available for rebar diameters of 8 mm, 10 mm, and 12 mm.
With type A of ARBOX® Joint Reinforcement, the rebar loops are cast into the structure during the first construction phase. In the second construction phase the steel cover is removed and the pre-bended rebars are straightened. The straightened rebars should overlap with the main reinforcement of the connected concrete element.
Comprehensive product information and detailed information on product characteristics, resistances and required operating conditions are available on product’s Technical Manual.
