FERBOX Specification

FERBOX is a reinforcement continuity system, designed to maintain structural continuity across construction joints in reinforced concrete structures. The casing houses suitably proven reinforcement, which is factory pre-bent and factory-fitted.

On the construction site, the FERBOX unit is secured inside the formwork at the front face of the structural member (often a wall), in advance of the concrete pour. The casing is designed to remain embedded in the concrete, providing a useful rebate and key for the subsequent concrete pour. The galvanized and indented profile of the embedded casing removes the need for traditional scabbling at the joint interface. After striking the formwork, the casing lid is revealed and removed, providing access to the connection legs (starter bars) which lay inside. These legs are bent outwards (at 90°) by the contractor, then ordinarily lapped with loose reinforcement of the subsequent structural member/ concrete pour.

Advantages

Almost infinite ability to create bespoke casing to reinforcement requirements.
Dedicated UK-local manufacturing facility for all ‘specials’ up to 16 mm diameter.
UK CARES approval for vertical as well as horizontal applications.

I’ve used your services on my last three projects (telescopic connectors for precast and continuity strip for in-situ). You’re very good at accommodating site demands for lead-in times and value competitiveness. Very happy with the service I’ve received on all three projects and hope this relationship will continue on future developments.

Paul Dean, Project Manager (Qcf), JP Dunn Construction Ltd

Thank you for sending the calculations and installation advice. The new calculation software looks great. Very clear, user friendly and with more design checks than the previous version. It’s a pleasure to see how you are constantly improving.

Stefan Pauceanu, Senior Structural Engineer, Ground Construction Ltd

Telescopic connectors provide us numerous advantages for precast stair installation. Apart from improved time and efficiency, the health and safety gains over traditional support methods are a key driver to satisfy our own needs, as well as those of our clients.

Shane Dunleavy, Project Manager, Morrisroe

As specialists in precast concrete car park construction, we use telescopic connectors for many key applications. Particularly, the BSF system helps us to construct a ‘modern’ frame without cumbersome corbel supports and enables rapid assembly on site. The technical back-up provided by Invisible Connections provides us with added reassurance.
