ARBOX® Strong provides the strongest rebar connection for concrete structures in Peikko’s product portfolio. It is an indented surface, highest resistance version of ARBOX® Joint Reinforcement, Peikko’s ready-to-install system for creating stiff concrete casting joints of reinforced concrete elements.
ARBOX® Strong has all the features and benefits of standard ARBOX®, plus an indented surface specified and designed according to Eurocode EN 1992-1-1, Section 6.2.5. It enables very high longitudinal and transverse shear forces to be transferred to the joint.
As with ARBOX®, ARBOX® Strong can be attached to formwork without having to penetrate or make other adjustments, and is available in various dimensions. It can be installed longitudinally or transversally, making it ideal for creating connections such as wall-to-wall, column-to-wall, and wall-to-slab.
The pre-bent 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 the fast construction of connections in both cast-in-situ and precast structures.
Based on the required resistance and dimensions, the suitable ARBOX® model can be selected using the tables in the ARBOX® Joint Reinforcement Technical Manual.
Comprehensive product information like resistances, required supplementary reinforcement, concrete grades, limitations of use etc. can be found within the Technical Manual. Product details may be country-specific. For design, always use product information that is localized for design's destination country. Country specific Technical Manuals can be found under Documents page, or from website of the country in question.
