Our research among patents revealed some systems that caught our attention:

• • FR2544359 discloses a concrete block having a pair of upstanding channels surrounded by a large void.
  • CA2585790 discloses a pair of slabs interlocked by panels; male-female connections are installed on top and bottom.

OBJECTIVES AND ADVANTAGES

There is a need on the market of construction for a lightweight block, made of concrete, rock or wood material, assembled parallel, angularly, radial, T-shaped, shaft-shaped blocks of spaced apart components requiring a minimum of attachment. The blocks are insulated and use insulating substances, like mineral wool, fiber glass, air, or other substance with insulating properties, inserted in a space between each concrete block.

DESCRIPTION OF OUR CONCEPT

Our concept includes the following elements, lightweight parallel concrete, wood or rock blocks provided with means of attachment, such as:

• • folded pins directed on opposite angles and possibly connected two by two by thin metal crosses passing around pins which reinforce the ends during construction of walls. The rows are held by passing through metal rods which position any two blocks in a series to form a wall. Mortar or construction glue is used around the rods to strengthen them.
  • Means of an adhesive fibreglass wrapping the blocks partially or completely to maintain them attached. Furthermore, the fibreglass is attached on a top face of blocks by means of inside small channels filled with epoxy glue or filled with a wire of nylon or metal enclosing the fibreglass within the channels.
  • Means of attachment of blocks is to pour a strong glue on a surface of contact of blocks and to strongly stick them together.
  • Another means of attachment are crossed ties attaching blocks two by two, pressed in notches dug on upper or lower surfaces of the blocks, and on their sides.

The blocks are insulated by inserting an insulating substance or by a void space between each parallel block.
