  • Patent number: 6637167
    Abstract: Disclosed is a method of construction of a wall from first, second and end modules each forming part of the wall. The method includes assembly of two modules being first, end or first and end modules having portions forming part of the wall by aligning these modules in a desired alignment and connecting them together with connection means to form a supporting structure for second modules. The connection means has a tie portion generally extending in the direction of the alignment. The tie portion has a portion corresponding with connection portions of a second module and cooperation of the corresponding tie portion, extending between guides formed as part of the tie portion, with the connection portions connects the second module to the supporting structure. In such manner, a portion of a wall may be constructed. Use of mortar of scaffolding and concrete pouring techniques may thus be avoided in construction of a structure.
