PSA has designed and produced an assembly to provide for the early bracing of pre-cast elements. Tested in accordance with AS3850.1:2015 Appendix A. Tested within 8MPa concrete, it also provides for the nominal standard specification of 12MPa as outlined in AS3850.1:2015. Concrete slabs achieving a minimum mean compressive strength of at least 8MPa may in-turn utilise the PSA EBS, subject to approval by the supervising engineer, with consideration to on-site conditions and final concrete strength for the projects requirements. PSA is obliged to follow the recommendations of AS3850.1;2015 Appendix A.
The PSA EBS consists of a customised early bracing chair, upon which the metal fix anchor is mounted. The void tube and cap completes the assembly in readiness for the concrete pour, achieving a 25kN+ pull-out capacity, in early cured (green), low strength concrete >8MPa. Pre-cut thread bars are stocked in 600mm lengths or may be made to specific order, subject to minimum volume requirements.
