Liftable foldable transportable buildings

A folded building structure transportable to a desired site at which the building structure is to be erected, comprising:

• (a) a fixed space portion including a planar rectangular first floor portion having first and second longitudinal floor edges, first and second transverse floor edges and a thickness, the first floor portion having a laminate construction comprising across the thickness (i) a first structural layer having a first face and an opposing second face;
• (ii) a foam panel layer having a first face and an opposing second face, the first face of the foam panel layer being bonded to the opposing second face of the first structural layer;
• (iii) a second structural layer having a first face and an opposing second face, the first face of the second structural layer being bonded to the opposing second face of the foam panel layer;
• (iv) a first edge reinforcement proximate the first longitudinal floor edge, and a second edge reinforcement proximate the second longitudinal floor edge;
• (b) a first beam reinforcing the laminate construction and oriented in a transverse direction, with a first end positioned proximate the first longitudinal floor edge and a second end positioned proximate the second longitudinal floor edge;
• (c) the first floor portion having between the first structural layer and the second structural layer (i) a first fork tube oriented in the transverse direction and spaced-apart to a first side of the first beam, the first fork tube spanning a distance from the first longitudinal edge to the second longitudinal edge so as to define a first aperture in the first longitudinal floor edge and a second aperture in the second longitudinal floor edge, (ii) a planar elongate longitudinally-oriented first fork tube plate positioned against and secured to the first edge reinforcement and to the first fork tube, and having a longitudinal length spanning a distance between the first fork tube and the first beam;
• and (iv) a planar elongate longitudinally-oriented second fork tube plate positioned against and secured to the second edge reinforcement and to the first fork tube, and having a longitudinal length spanning the distance between the first fork tube and the first beam.
