application 'alea July 1o, 191s. serial No. 24eme.
To all whom, t may concern.' y
e it hewn that I, JOHN 0. MADISON, a citizen'of the United States, residing in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Trussed- Sheet Construction, of which the following is a specihcation.
y invention relates to improvements in trussedsheet construction adapted. for use in the construction of walls, partitions, Hooring, ceilings and other structural purposes in buildings. My present invention covers certain modifications and specic embodiments of thel general invention disclosed in my application Serial No. 106,823, filed June 1916, for trussed sheet building material.
ll`he application `referred to describes a construction embodyin y a pair of sheets, preferably of steel, wiichconstitute the outer chord members of the trussed construction and which are rigidl connected together at certain intervals by intermediate web members composed of integral projections or depressions formed on one or both sheets and separated from each other 1aterally and longitudinally, these projections or v depressions being of a depthv many times the till' thickness of the sheet so as to produce a strong truing efect. My present improvements relate to details of construction, including a construction in which a layer of insulating material is secured between the inner ends of corresponding depressions formed on the two sheets of the structure. ltlly invention also includes a means for stiffening such a structure and at the same time forming anchorage for a layer of cement or other plastic material thereon. this comprising a reinforcing plate secured on one of the sheets of the trussed structure with openings `through the reinforcin plate registering with the depressions in t e underlying sheet, these openings, however. being of less extent than the adjacent portions of the de pressions, so that the portions of the plate overlapping the depressions will form anchorages for the plastic materlal osltloned on the sheet and plate. Another eature of the present invention consists in a manner of increasing the depth of the depressions formed in t e sheets by slitting the metal at the sides of the depressions in a manner to be described, whereby steel or other metal of poor quality may be more readily pressed' to form depressions of considerable depth, the openings thus formed also bein of use as zonstituting anchorages Vfor 'plastlc mater1a v In order that a clearer understanding of my invention may be had, attention is hereby directed to the accompanying drawings forming part of this application and illusn trating certain features of my invention. In the drawings, Figure 1 represents a sectional view of a trussed sheet construction provided with an interposed insulating sheet and 'also with a reinforcing and plasticanchoring plate, Fig. 2 is an enlarged partial section through a trussed structure in which the depressions are slit for the purpose of increasing the depth thereof, Fig. 3 is a cross-section ,taken on `line 33 of Fig. 2, and Fig. 4 is a top plan View, partially broken away, of the construction shown in `eferring to the constructionV shown in Fig. 1, a pair of metal sheets 1 and 2, preferably of steel, constitute the outer chord members of the trussed structure and are spaced apart in a substantially parallel relation by intermediate web members which are formed integral with said sheets. The web members of the truss take the form of deep -depressions which may be formed as by presslng, rolling or molding. In the construction illustrated in Fig. 1, both sheets are provided with such depressions shown at 3 and 4. These depressions are of a depth many times the thickness of the sheets 1 and 2 vfor the purpose of obtaining a strong truss-like structure. y
, Plastic material 9, such as concrete. being positioned upon sheet 1 and plate 7 and lling the depressions 3 will be securely anchpred in` position by the portions of plate 7 extending partway over the depressions, as is indicated in Fig, 1, the plate 7 having an additional function as a reinforcing means for the trussed structure.
- In Figs. 2 and 3 is illustrated a method of obtaining an extreme depth of depression in the case of a trussed sheet structure, such as that shown in Fig. 1 or in the drawings forming part of my application Serial No. 106,823 referred to above. As is shown in Fig. 2, a sheet 1 having depressions, such as that illustrated at 3, forms one of the chord members of the truss and is rigidly secured to a sheet 2 forming the other chord member of the truss, which sheet may be plane, as shown, or may be provided with depressions in the same manner as the under sheet shown in Fig. 1. The sheets are secured together at the apices of the depressions by suitable means, such as rivets, one of which is shown at 6 extendin through sheet 2 and the apex portion of epression 3 of sheet 1. l
In the construction illustrated, each depression, such as 3', -is -provided with slits 10, 10, running transversely of the center line or depth of the depresslon on each side thereof. This construction is particularly adapted for obtaining extreme depth of depressions in pressing sheets of a cheap grade of steel or other metal, which 1s not adapted, because of its qualities, to be pressed to a desired depth by ordinary methods. It is obvious that slitting the metal in the manner shown permits a greater depth of depression to be pressed than would be obtained with the same pressure if no Such slits were provided, and the stresses in the metal are correspondingly less. The sheet 1 being covered with a layer of plastic material 9', such as concrete, which lls the various depressions, it will also be noted that the plastic material will be forced somewhat through the slits 10 to form a suitable anchorage for the plastic-material.
What `I claim is 1. In a trussed sheet structure, adapted to withstand heavy loads or stresses, the combination of a sheet constituting a chord member of the truss and formed with permanent integral depressions of a depth many times the thickness of the sheet, sufficient to produce a stron trussing effect, said depressions being suital ly spaced laterally and longitudinally and constituting web members, another sheet rigidly secured to the apices of said depressions and constituting an opposite chord member of the truss, a reinforcing plate secured to said first sheet, extending over said depressions with openings therethrough in line with said depressions, of less extent than the adjacent portions of said depressions, and a layer of plastic material applied to said first sheet and p late and filling said depressions, said material being anchored to said sheet by the portlons .of said plate overlapping said depressions.
2. In a trussed sheet structure, adapted to withstand heavy loads or stresses, the combination of two sheets constituting the opposite chord members of the truss, each formed with permanent integral depressions of a depth many times the thickness of the sheet, suiicient to produce a strong trussing effect, said depressions being suitably spaced laterally and longitudinally, and a layer of insulating material, said depressions being rigidly secured together at their inner ends with said insulating material interposed between them and secured'thereto, said depressions constituting the web members of the truss.
3. In a trussed sheet structure, adapted to withstand heavy loads or stresses, the combination of a metal sheet constituting a chord member of the truss and formed with permanent integral depressions of a de th many times the thickness of the sheet, su cient to produce a strong trussing effect, fsaid deroeeee it pressions being suitably spaced laterali and longitudinally and constituting We members, another metal sheet rigidly secured to the apices of said depressions and constituting an opposite chord member of the truss, said depressions being slit through opposite sides thereof transversely or' the depth thereof for substantial distances, and
seid slits widened by the pressure employed in the formation of seid depressions.
This specification signed and witnessed this 29th day of June, 1918.
