Floor and Roof System

The Guardian Floor and Roof System produced by Concrete Building Concepts has proven itself to be a cost-effective solution that is stronger, more durable and faster to install than traditional floor systems.

Produced off-site at our production facility, the Guardian Floor and Roof System can be easily installed on steel, precast concrete and site-built concrete structures. Designed to provide precise adjustments and fine tuning, Guardian Floor and Roof System panels can form the roof of a single-story building. For multi-story structures, the panels form the elevated slab of an upper level and simultaneously provide the ceiling attachment points for the level below. The embedded steel bar joists incorporated in the Guardian Floor and Roof System provide ample space for the easy installation of ventilation ducts, electrical lines and plumbing lines. A variety of joist depths can be selected to facilitate the placement of trade requirements and ceiling attachments such as step-downs and coffers. Openings in any slab can be precast at the production facility.

The Guardian Floor System is fabricated in widths of up to 8 feet and lengths of up to 40 feet. It is typically composed of two 8" - 22" deep steel bar joists 48 apart which are embedded in 3 thick reinforced concrete. The open web bar joist has a bottom chord constructed with double structural angles that acts as an axially loaded tension member with smooth round bars used for diagonal web members. The diagonal web members acting in tension and compression are welded at the top with a longitudinal member embedded 1 1/2 deep into a top chord comprising of a 3 concrete slab poured with 3000 psi concrete and reinforced with 6x6 welded wire mesh. The slabs are cast in continuously cambered steel forms to allow deflection control and result in a fine steel-float finish superior to poured-in-place concrete.
The panels are transported to the building site and placed on top of precast concrete panels, tilt-up panels or beams of the structure, precisely leveled and welded together at the joist seat and parallel slab joints. The slab joints are then grouted. All materials meet and exceed standards and specifications for local and national codes.
