Patent attributes
The present invention is concerned with a building system comprising i) at least first and second hollow blocks each having at least one side wall, and at least two end walls extending in at least one common direction, at least one of the walls in each block having a given thickness and being provided with a first cut-out extending throughout said wall thickness at a first free end of said wall, and ii) at least one connector element defining a cylindrical hollow body having a shape and size conforming with a perimeter corresponding to a juxtaposition of said first and second cut-outs for snug engagement within the perimeter, and at least one first flange projecting from a first end of the body and at least one second flange projecting from a second end of the body, said first and second flanges defining an intermediate spacing substantially equal to twice the value of said thickness. Thereby, the first block can be connected to the second block for erecting structures by registering cut-outs of adjacent walls against each other and connecting said adjacent walls together by snugly positioning the connector element in the cut-outs with first and second flanges abutting respectively on inner faces of each of the adjacent walls.
