Prefabricated transportable concrete floor system and method for

Abstract

A prefabricated monolithic reinforced concrete floor system is disclosed and claimed. Open web trusses are provided along a longitudinal dimension of a floor frame with rectangular tubular beams secured therebetween. Reinforcing elements are secured along upper surfaces of the open web trusses and the tubular beams where a floor is utilized and a reinforcing mesh material is draped thereover. Reinforcing clips may be received about the peripheral reinforcing elements to further reinforce edges of the floor. The concrete slab is produced in situ about the frame and totally encapsulates the reinforcing elements present while a lower surface of the slab is coterminous with an upper surface of the open web trusses and the tubular beams. The concrete floor may be transported for significant distances without damage thereto, while utilization of the open web trusses longitudinally along the length of same permits floor sections to be placed side-by-side with utility services being indiscriminately passed through the open spaces. The process for producing the floor is achieved by removably securing formwork to the frame with internal segments extending upwardly between the floor purlins and with an upper surface of same generally coterminous with an upper surface of the floor purlins, whereby the lower surface of the concrete slab does not extend downwardly around the floor purlins. The formwork further includes peripheral edge forms of a predetermined height. With the formwork secured to the floor frame, the composite may be transferred to a remote site for pouring, finishing and curing of the floor. The floor and process for producing same according to the present invention find preferable use in building modules that are fabricated in a factory environment and transported to a building site.
