Abstract
A flooring system that folds up to form a large crate. This crate can be used to hold constructions materials for the building to be built on the floor. The crate is designed to be placed on a foundation. The crate is placed on top of the foundation in the center, perpendicular to beams that make up part of the foundation. Once the base is in place on the beams the crate is unfolded and a flat floor is achieved. All of the pieces of the crate have the flanges that fit onto the beams. They can then be fastened to the beams to secure them in place. The system uses a unique hinge and locking system. At the edges of the sides of each floor panel of the crate are torque tubes that support a cam link and a cam arm that are used to fold and unfold the floor.
