UNITED STATES PATENT OFFICE.
JOHN O. MADISON, OF BROOKLYN, NEW YORK.
TRUSSED BUILDING CONSTRUCTION.
T0 all whom may concern.' V
Be it known that I, JoHN O. MADIsoN, a citizen of the United States, residin at Brooklyn, county of Kings, andState of ew York, have invented certain new and useful Improvements in Trussed Building Construction. embodying a pair of sheets, preferably oi steel, which constitute the outer chord members ot the trussed construction and which are rigidly connected togetherat certain intervals by intermediate web members composed of'integral projections or depressions formed on one or both sheets and separated from each other laterally and longitudinally, 4these projections or depressions being of a depth many times the thickness of the sheet, so as to produce a trussing effect.
.My present invention relates to a construction in which the lower chord member of the truss is a metal sheet, which in some forms `of the invention is provided with the deepintegral depressions referred to and in other forms may be plane. The truss construction is formed by securing such a sheet to a metallic member of open construction which is partly or wholly embedded within a layer of plastic material such as concrete.
metallic member of open construction, I
refer to a wire mesh or metal lat-h or ex` panded metal or the like. .The wire mesh,
for example, may extend over and be welded or otherwise secured to the apices or upper ends of the integral depressions formed on the metal sheet which constitutes the opposite chord member of the truss, which may be covered with a plastic material, such as concrete, which extends to a greater or less extent through the interstices `or the wire mesh and is thereby anchored to the same without the necessity of providingr any special anchoring devices therefor. Or the Specification of Letters Patent. l Patented June 29, 1920 Application filed January 6, 1919 Serial No. 269,749.
la er of plastic material may be formed with the metallic member of open construction, such 'as wire 4 mesh, entirely embedded` therein, and securing devices, such as bolts, .also embedded in the concrete and extending beyond a surface thereof, these bolts being secured to the wire mesh member. These securing devices will be rigidly secured to the apices of the depressions on the metal sheet which are in alinement with the securing devices. Or an expanded metal member may be embedded in the plastic material with the lower portions thereof extending beyond a surface of the plastic material in position'to be welded or otherwise secured to the apices of the depressions on the lower sheet. Or, in case the lower sheet is not provided with depressions or projections, the
' lower portions of the expanded metal mem- 75 ber may be Welded or otherwise secured to the fiat surface of the lower sheet so as to leave a lspace between the plastic material and the lower sheet, the trussing effect being obtained 'in this case by the portions of the 80 expanded metal connecting the upper and lower/portions of the same. Constructions such as those indicated will be of very considerable strength and rigidity and also will be quite economical to manufacture since the wire mesh and expanded metal material are comparatively inexpensive.
.In order that a clearer understanding of my invention may be had, attention is hereby called to the accompanying drawings forming. part of this application and illustrating certain embodiments of my invention.
In the drawings, Figure 1 represents a partial cross section through a construction embodying my invention; Fig. 2 is a top plan view of the same with certain parts broken away; and Iigs. 3, 4 and 5 are partial cross sections through constructions illustrating modified forms of my invention.-
Referring first to Figs. l and 2 of the drawings, one of the chord members of the truss, which I willrefer to as the bottom chord member, comprises the sheet 1, preterably of pressed steel or of other suitable metal, the web members of the truss being formed by the deep depressions 2 which are integral with the sheet 1. These depressions may be formed by a suitable method such as pressing, rolling or molding the sheet and are of a depth many times the thickness of portions 9 and preferably the lower parts of the connecting portions 10 will extend beyond the surface of the plastic material. Or the expanded metal member may be secured to the sheet 1 and the plastic material poured thereon so as to extend through the openings of the expanded metal member and to partially or. entirely fill'the same and extend above the same. Preferably, a space is left between the plastic material and the sheet 1', as illustrated, which may be used as an air space or illed with insulating or filling material, if desired; In this case, as well as in that illustrated in Fig. 4;,- the metal of the expanded member is so stretched that the distance between the upper and lower portions 8 and 9 is equal to many times the thickness of the metal employed, so that a strong trussing effect will be obtained anda strong and rigid structure provided with the use' of a metal sheet which may be comparatively thin and light.
What I claim is:
1. In a trussed structure, adapted to withstand heavy loads or-stresses, the combination of a layer of plastic material, a metallic member which is wholly open in character and at least partly embedded in said material throughout its area, said member extending throughout the lineal extent of said material, and a metal sheet parallel to said layer and to the general direction ofvsaid member and rigidly secured to said member, said sheet and member being so constructed as conjointly to form a truss.
2. In a trussed structure, adapted to with l stand heavy loads or stresses, the combination of a layer of plastic material, a `metallic member which is Wholly open in character and at least partly embedded in said Imate-A rial throughout its area, said member extending throughout the lineal extent of said material, and a metal sheet parallel to said layer and formed with permanent inte ral depressions of a depth many times the thickness of the sheet, spaced apart laterally .and
longitudinally, the apices of said depressions being rigidly secured to said metallic memA ber of open construction.
3. In a trussed structure, adapted to withcuring devices. f
a trussed structure, adapted-to withstand heavy loads or stresses, the combination of a layer of plastic material, a sheet of expanded metal having upper andz lower separated portions, said sheet being at least partly'embedded lin said material, and the distance between said up er and lower portions being many times te thickness of the metal employed in said sheet, said portions being connected by connecting portions adapted to produce a strong trussing effect, and a second sheet rigidly secured to said expanded metal sheet.
5. In a trussed structure, adapted to withstand heavy loads or stresses, the combination of a layer of plastic material, a sheet of expanded metal having upper and lower separated portions,said sheet being at least partly embedded in said material, and the distance between said upper and lower portions being many times the thickness of the metal employed in said sheet, said portions being connected p by connecting portions adapted to produce a strong trussing effect, and a second sheethaving permanent depressions of a depth many times the thickness of the sheet, spaced apart laterally and longitudinally, the apices of said depressions being rigidly secured to the lower portions of said sheet of expanded metal.
This specification signed and witnessed this 3d day of January, 1919.
