Concrete floor system and method of making floor components

Abstract

A concrete floor system used in a building structure and a method of making floor components used with the floor system. The concrete floor system, if installed on grade, provides for expansion and contraction due to expansive soils and eliminates cracks, which heretofore occurred in poured concrete slab floors. The concrete floor system includes a plurality of parallel concrete beams. The beams can be made up of hollow concrete blocks for reduced weight and receiving a tension cable therethrough. Also, the beams can be either solid pre-cast beams, solid pre-cast, pre-tension beams or solid pre-cast, post-tension beams. Opposite ends of the cable are held on end plates inside recessed ends of each hollow beam. The ends of the beams are adapted for mounting next to the inside of the sides of a building foundation wall. The beams can be in a range of 5 to 20 feet and greater in length depending on the dimensions of the concrete floor. A top portion of the each parallel beam is adapted for receiving a plurality of angular shaped floor panels. The floor panels interlock next to the top portion of the beam. The floor panels and concrete blocks, used in making up one of the embodiments of the concrete tension beams, are readily adapted for making in a standard high production concrete block machine.
