Building system

A precast transportable construction body for a building system, the precast transportable construction body comprising:

• a first reinforcing mesh and a second reinforcing mesh defining a steel framework, each reinforcing mesh being substantially flat;
• a plurality of substantially spheroidal bodies sandwiched between the first reinforcing mesh and the second reinforcing mesh;
• each of the plurality of bodies comprising a plurality of protrusions, and each protrusion being configured to fasten to at least one of the first reinforcing mesh and the second reinforcing mesh such that the plurality of bodies are fixed to and directly connect the first reinforcing mesh and the second reinforcing mesh;
• a plurality of bottom connector chairs attached to the second reinforcing mesh, each bottom connector chair comprising first and second apertures to allow insertion of substantially parallel rods of the second reinforcing mesh, each bottom connector chair being attached to the second reinforcing mesh by inserting at least the substantially parallel rods of the second reinforcing mesh into the first and second apertures;
• a plurality of trusses to support the connection between the first reinforcing mesh and the second reinforcing mesh in a spaced apart relationship with respect to each other, each truss comprising an upper rod and two lower rods joined together by a pair of zig-zag shaped rods, the zig-zag shaped rods being joined together at the upper rod and each zig-zag shaped rod attached to a lower rod defining a triangular cross section of the truss, with the bottom connector chairs arranged to secure the two lower rods of the trusses to the second reinforcing mesh;
• and
• a hardened material;
• wherein the plurality of substantially spheroidal bodies are arranged and positioned between the first reinforcing mesh and the second reinforcing mesh such that the steel framework formed by the first and second reinforcing meshes substantially determines boundaries of the precast transportable construction body;
• and
• wherein the plurality of substantially spheroidal bodies are arranged such that spaces are defined around and between each of the plurality of substantially spheroidal bodies that define a regular series of internal pillars of the hardened material that provide the precast transportable construction body with load bearing capability.
