REENFORCED PLASTIC STRUCTURE 7 Filed June 30, 1928 INVENTOR dwwimmf Patented Mar. 22, 1932 EDWARD L. rnnnniomi or rrr'rsnunen, PENNSYLVANIA, Assreixr'onfro izti' rsje i'nq'n STEEL COMPANY, F*], ITTSBURGH1,PENNSYLVKNIAQ A ccnromlrron OFPENn SYLV'ANIA Application filed June 30,

My invention relatesfto reenforc'ed struc tures of concrete, plaster, and the like, such as walls, partitions, slabs, etc.

One object of my invention isto provide a structure of concrete, plaster'for the. like,

wherein reenforcement 1 iseffectively embedded and wherein nospecial-or temporary forms are required in the making of the body.

Still another object of my invention is,

to simplify and improve generally bodies formed of plastic material and the method of making the same.

One manner in whichmy invention may be practiced is shown" in. the accompanying drawings, wherein Figure 1 is a fragmentary 'front elevational view-of a wall or slab constructed according to my invention; Fig. 2 is an edge elevational view'of the-structure of Fig. 1, at one stagein the process of making the same, and Fig, 3 is a view similar to Fig. 2, but showing the process of manufacture continued to the stage at Whicha slab or block is formed.

' 'In practicing my invent-ion according to the manner shown in the drawings,I provide main reenforcing members consisting of bars or'wires 4 and 5 that may be welded orother- V wise suitably connected at their-points of intersection to forma mesh-like body. 1A back-i. ing sheet 60f wire cloth or the like isattached to the mesh formedby the bars 4and5, by means of thread-like Wires ,7 which are dis posed mainly to the rear of the sheet 6,. as shownjmore clearly'in.Fig;2,; and at. intervals have-bends 8lformed therein-that extendto the front of the sheet 6 and around certain of thestrand wires orrods 4, somewhat after 7 the manner shown in my Patent No. 1,597,507,

I may be applied to the front ofthe'sheet by issued August 24,1926. V

means of a trowel, a cementgun, or "in any other suitable manner. Ifthe mesh structure be placed against studding,f and it is "desired to face only theoutersidgas infthecase of REENroRcEn i walls or'partitionsp the --completed structurewill have, when viewed 1 in fsectiomithe Paps pearance showir 2,5the; plaster facing 9 bei ngof courseapplied teenydesiredthick ness, and completely surrounding the barsA and 5. It. will also be seen that an interlock}: ing effect tan be ha 'dbetwen the {plaster and the wire: :clpth "or. 'backing' sheefi 6,:by reason Q of the}. fact; that small, portions 16f the plaster may be forced through such sheet, as indicat-V ed at 10. The wire cloth therefore not'only serves as a backing or form sheet, but-also assists in reenforcingand permanentlysupporting the, plaster body since the openings-,1 through the backing sheet are so close together that the portions of plaster which are forced therethrough will unite at the rear side ofthe, sheet to effect substantially complete imbedment thereof as shown in Fig. 2, where the protrusions 10 are shown as united together fora distance substantially equal to the thickness of the thread Wire 7. The por-z tions 10 of the plaster will of course be come pressed when being forced through the backing sheet and relief of such pressure at the rear side of the backing-sheet will effect the slight expansion thereof, necessary to cause them to unite attherearsides of the wires forming the backing sheet 6.

If it is desired to form a slab or to finish both'sides of the structure by a plaster facing,

I apply a facing 11 (Fig. 3) to the rear side of the structure of Fig., 2,to any desired depth. 2

6 need not be of wire cloth but may be of vari- An effective interlocking of the rear facing 11 ous other material such as fiber, paper, orthe like, .having perforations through which y plaster may be forced when facing one side of the sheet. It will also be understood that various forms of reenforcementother than the Y bars 4 and 5 may be utilized.

When thebacking sheet 6 is supported in spaced relation to the mesh bars 45,, as; shown in the drawings, the said bars. are

thereby permittedto be completely surround fed by the main bodyYofI plastic materialjso that they are completely imbedded and more efiectively reenforce the body than if the backing sheet were disposed directly against the bars.

While I hereinafter claim'the structure as a plaster body, it will be understood that the term plaster is used in abroad sense, to include concrete, Various stucco materials, etc.

V I claim as my invention 7 v A plaster body composed of a reenforcing mesh, a loosely-woven wire cloth backing sheet disposed rearwardly of the mesh, tie

members supporting the cloth in completely spaced relation to the mesh, and plaster mate rial completely imbedding the mesh and having protrusions extending through the wire clothand partially imbedding the same, the strands of the cloth being spaced apart such distance as to permit the said protruding portilonfi of the material to'be forced through the c ot In testimony whereof I,the said EDWARD L. BENEDICT, have hereunto set my hand. EDWARD L. BENEDICT.
