Three dimensional reticulated structure
Abstract
Abstract A three dimensional, open mesh structure is described which is fabricated from sheet stock of metal, paper or the like. The sheet stock is slit in a predetermined pattern and then is expanded to form the structure. The structure has a three dimensional shape with a reticulated pattern of apertures in planar surfaces transverse to the plane of the sheet material prior to its expansion. The structure is formed by a plurality of unbroken, continuous trips of material lying in a plurality of superimposed planes, each strip having a sinuous path departing in regular frequency to either side of a medial line with web sections lying on said medial line where each strip is in joined, unbroken attachment to immediately adjacent strips and with each pair of such adjacent strips defining said apertures. The structure is useful to form the core of a wall with elongated reinforcement members disposed perpendicular to the planar surfaces and extending through superimposed apertures of the reticulated pattern. The wall comprises the aforementioned assembly of reinforcement members and three dimensional structure with a plastic material such as plaster encasing the assembly.
