Abstract

A system of modular, hollow interlocking building elements which can absorb large horizontal or vertical pressures, and thus eradicate or minimize the effects of active pressure. The elements can be connected along each face and stacked one upon the other to form a stable, continuous, multi-directional structure, requiring no cement or other stabilizing material. The system comprises a plurality of base elements, having on slits on the vertical faces, and a plurality of interlocking elements to form layers above the base, having a slit in each of two, three or four vertical faces. The elements are arranged so that the faces having no slit form the outer surface, thus forming a structure having a smooth, continuous outer surface. The elements can be filled with any required filling material. The elements may be used in construction of structures in which active pressure is a factor, such as retaining walls, bridge abutments, ramps and the like.

A system of modular interlocking framing elements capable of receiving filling material and absorbing the active pressure generated thereby, said system comprising:

a plurality of rigid, hollow polygonal framing elements each having a plurality of only vertical faces, joined at their edges,
a first portion of said polygonal elements provided as base elements arranged as a base layer,
a second portion of said polygonal elements provided as interlocking elements arranged as an intermediate layer above said base layer,
a third portion of said polygonal elements provided as interlocking elements arranged as an upper layer above said intermediate layer,
said interlocking elements in said intermediate layer each being formed with a single vertical slit extending upwards from the mid-point of the lower edge of each of said vertical faces, said vertical slit having height equal to half the height of said vertical face and width equivalent to the total thickness of two of the walls of said base layer elements to be inserted therein,
said interlocking elements in said upper layer being formed with a single vertical slit extending upwards from the mid-point of the lower edge of at least two of said vertical faces said vertical slit having height equal to half the height of said vertical face, and width equivalent to the total thickness of two of the walls of said intermediate layer elements to be inserted therein,
such that each of said vertical slits formed in said vertical face of said intermediate layer elements engages said base elements at a horizontal mid-point of said vertical face of said base elements,
and each of said vertical slits formed in said vertical faces of each of said upper layer elements engages said intermediate layer elements at a horizontal mid-point of said vertical face of said intermediate layer elements,
such that said base layer elements are aligned with said upper layer elements to form a smooth, continuous outer surface,
said base, upper and intermediate layers providing a staggered, mortarless, multidirectional load-bearing construction.
