Abstract
This modular building wall unit comprises a hard foam layer and a concrete layer intimately bonded to each other along an interface between the layers. A reinforcing wire mesh matt is embedded in the hard foam layer and reaches with anchoring elements into the concrete layer which may also have embedded therein a further wire mesh matt. The present units are cast in a mold by first keeping the mold horizontally and filling it partially with the hard foam. When the hard foam is sufficiently cured, the mold is brought into a substantially upright position, closed and filled with the concrete mix. Of course, a top portion is left open for the filling.
Claims10
A modular load bearing building wall unit comprising a hard foam layer having an inner surface and an outer surface, a concrete layer intimately bonded to said inner surface of said hard foam layer, a reinforcing wire mesh mat embedded in said hard foam layer and having wire portions extending from the plane of said first mat into said concrete layer for intimately bonding said foam layer to said concrete layer, said wire mesh mat being completely covered all around by said foam layer at both sides thereof, and core elements of a material lighter than the material of said concrete layer, said core elements being completely embedded in said concrete layer.
A modular load bearing wall unit comprising a hard foam form member forming a part of said wall unit and a concrete layer intimately bonded to said form member, said form member comprising a layer of hard foam material having rim portions extending from one surface at the edges thereof, a first wire mesh mat embedded in said layer of foam material and having wire portions extending from the plane of said first wire mesh mat through the surface from which said rim portions extend, said concrete layer being in intimate contact with said one surface substantially throughout its extent, whereby said wire portions extend thereinto for bonding said form member to said concrete layer, said concrete layer having a thickness equal to the height of said rim portions of said foam member, said first mesh mat being completely covered by the foam material of said form member at the other surface of said layer.
