Abstract:
1. A method of constructing a concrete building module, comprising the steps of: providing a plurality of metal connection plates comprising groups of wall panel connection plates and roof panel connection plates, each connection plate having a plate connection means and a plate anchor means; pre-casting with concrete a plurality of exterior wall panels having exterior wall panel faces and exterior wall panel ends with the plate anchor means of at least one said wall panel connection plate embedded in an exterior wall panel face of each at least one exterior wall panel such that the wall panel connection plate is adjacent an exterior wall panel end; pre-casting with concrete at least one roof panel having roof panel faces and roof panel ends with the plate anchor means of at least one said roof connection plate embedded in a roof panel face of said at least one roof panel such that said at least one roof connection plate is adjacent a roof panel end; forming a horizontal floor panel; placing the exterior wall panels upright and end to end on said floor panel to define an enclosure such that connection plates of adjacent wall panels register with and are immediately adjacent to each other; welding adjacent said wall panel connection plates together to secure said exterior wall panels in their positions relative to each other; placing said at least one roof panel across and on top of a plurality of said exterior wall panels such that roof panel connection plates register with and are immediately adjacent to wall panel connection plates; and welding adjacent said at least one wall panel and roof panel connection plates together to secure said at least one roof panel and said exterior wall panels in their positions relative to each other to define a concrete building module.
