Abstract

A panel consists of a settable filler, e.g. mortar, applied to one face of a reinforcement sheet. The sheet is of a tensile material, e.g. metal, and has pressed out rows of square waved arched strips 2 separated by planar rows 1. The arches 2 in adjacent rows are mutally staggered. The filler is encased in the arches 2 and the sheet provides a tensile reinforcement to both sides of the panel. <IMAGE>

Description

A Conversion Pressing for making reinforced panels of various fillers.

This invention relates to a reinforcing means for making panels of different types of filler materials using a single sheet of tensile material to reinforce both sides of a proposed panel through the means of a shear conxz~rsi:in mechanism which converts the shear value of the filler into tensile strength on the pressed out or weak side of a filled conversion pressing.

Panels of solid fillers such as a mortar mix have been reinforced by asbestos, epoxy coated glass fiber, vinyl acrylic fibers, wire mesh, expanded metal lath, surface laminates and possibly cast in facings with punched out tabs.

Prior reinforcing does not reinforce and cross connect both sides of a panel with a single sheet which this invention does through the means of rows of arches whichencasevolumes of filler and converts its shear value into tensile strength in the tops of the arches. This shear conversion mechanism can be used in panels from a tenth of an inch through three inches thick.

A conversion pressing will have a strong and a weak side. The strong side will support loads in excess of what is now available and the weak side will resist the loads of handling and transport without the failure due to weakness and brittleness which is associated with traditionally reinforced panels. Filled Conversion Pressing panels can substitute for plyzs70od, sheetrock, fiber and metal panels. Other uses are possible with pressings made from plastics and other fillers.

One way of carrying out the invention is described in detail below with reference to the drawings which illustrates one specific embodiment in which: Figure one shows an isometric of a typical pressing which in this case is one half inch thick for a one half one thick panel. The pressing can be filled from the topside which is up in the drawing.

Figure two shows a plan of the pressing and figures three and four shows sections through the pressing. Figure five shows a projection of the areas or volumes of filler in shear in the mechanisms. Figure six shows a detail of the shear conversion mechanism.

The figures all show the conversion pressingcomprising the continuous strips 1 which reinforce the strong side and which are connected at the landing zones 4 to the pressed out arched strips 2 in which all the arches are a uniform height and are offset to each other. Number 3 the outlined and hatched areas are those portions of the filler which are in shear when the weak side is under tensile stress.

In accordance with the improvement,an invention,figure two shows a plan detailing the proportional relationships of the parts of the pressing 1,2, and 4. Generally the arched strips should not be wider sixty percent of the depth of the pressing and the landing zones 4 being not less than the width of the continuous strips 1 nor longer than one third the length of each arch which as part of the square waved arched strips 2 has an encasement of filler 3 in shear at the end thirds of each arch that is one encasmaentt each end being at least one third of the length of each arch long.

Figure three shows a section throught the encased filler and figure four a section though the landing zones 4.

Further in accordance with the invention and in detail the shear conversion mechanism detailed in figure six in which the mechanism comprises an encasment of filler between the continuous strips on the bottom 1, the radiused entry into each arch 5, the rising sides of adjacent arches 6 and the radiused exit 7 of adjacent arches into the tops of each arch 2. Figure number five shows the portions of filler as a gang running the length of a pressed sheet or conversion pressing.

The encasments or shear areas are shown hatched as 3 which converts the shear value of the filler into shear across the overlapping tops 2 of all the arches running the length of the pressing.

A Converison Pressing can be made using a rolling die and footprint or a panel sized die and footprint. In both cases a die can be made from an assembly of ganged teeth each of which would comprise a cast and machined single arch and half of the surrounding area such that a number of teeth can be welded together to make a panel sized sheet or rolling cylinder from which a footprint could be made.

   A Conversion Pressing for making reinforced sheets of various fillers such as a mortar mix can comprise a single sheet of gauge thickness tensile material into which are pressed rows of continuous and alternating straight strips 1 and continuous and alternating square waved arched strips 2 which are connected to the straight strips at landing zones 3 which occur between each arch: zones which are joined on each side to the straight strips and zones which are preferably not longer than one third the length of each arch nor shorter than the width of the widest strip which would preferably not be wider than sixty percent of the depth of the pressing and further each row of square waved arched strips will be one half overlapped to each adjacent arched strip such that a side view of the overlapped arches is characterized by tensile material of each arch having a radiused entry 5 into inwardly sloping sides 6 and a radiused exit 7 into flattened tops 2 which are parallel to the straight strips 1 where between the straight strips 1, the sides 6 and the tops 2 of adjacent arches would show an encasment of filler 3 being not shorter than one third the length of each arch.
