'PERMANENT SHEET-METAL CENTERING.
Specification of Letters Patent. Patented Sept, 21, 1909,
Application med may i9, isos. seriai No. 433,687.
To all ttvhom 'it 'may concern:
Be it known that I, JLIUS H. SGHLAFLY,4
l a citizen of the United States, residing at ,anton, in the county of Stark and State of Ohio, yhave invented certain new and-useful Improvements in Perm'anent Sheet-.Metal Centering; and I do hereby declaretliatthe following' is a full, clear, and exact description of the same, reference beinghad tothe vannexed drawings,making a part of this specification.
The object of my invention is to so form the sheets that they can :be connected together so that the' lapped portions of the cor-f rugations will be so locked in such a manner that there can be no relative movement as between any two or more sheets after they have been connected together and the` cement placed in. position `and afterward `transformed from' a'plastic state to 'a rigidi condition.
Referring to the, drawings; Figure 1y is a view illustrating two of my improved binds ing sheets connected together and illustrating the sheets partly covered withcementlwork. Fig.f2 is a view show-ing aportion of two sheets 'spaced' from each other and in proper relative position to be connected or.join ed together. Fig. 3 is a sectional view. Fig. 4 is a view showing'twosheets connected to` gether, section being taken on the line 4-4 in Fig. 3 and the plane of said view being at right angles to the sectionof Fig. 3.
Similar numerals of reference indicate corresponding parts in all the figures of the drawing.
My impoved structure comprises a sheet of metal nt into similar parallel ribs alter` nately projecting in opposite directions, dove-tailed in cross section and having their exterior faces lying in parallel planes, the .thickness of the ribs being small in compari son with the other dimensions of the sheet.
' In the accompanying drawing, 1 repre sents' the binding sheets, which are formedof metal and of any, desired size and thickness reference being had to convenience in manufacture and the specific use or place where thev sheets are tobe used. For the purpose of the sheets -they alternating corru- `are provided with the dove gations 2 and spaces 3, which are l tailed for a portion of their length. For the purpose of causing the cement to better adhere to. the surfaces of the sheets, said sheets 4surfaces of the binding sheets.
are provided with roughened surfaces, which .roughened surfaces may be formed as shown and as 'shown the surfaces consist of corrugations, but in the present instance other forms may be employed as the only object to be accomplished is toprovide the sheets with surfacesl so formed that when the cement becomes set there can be no relative movement at; ai1y. point as between the cement and thenietal sheets and at the same time pio ducean equal adhesiveness as between the cement and the surfaces of the sheets at all points, thereby preventing any slipping);`
movement of the concrete work upon the This is an important feature, owing to the fact that if vthere is any -relative movement as between the sheets and the concrete work such move- Vmenthas-a tendency to crack or break the concrete work after it becomesset. In structures extending over considerable space it is necessary to join a number of sheets together and4 in order to provide for connecting the sheets so that the Aalternating spaces and corrugations may be continued in parallelism the endsofthe sheets are provided with the conveXo-concave portions 4, which portions are struck or formed from the metal constituting :the corrugationsy and spaces.
Aconvexo-concave portion 4 is formedin each ridge 2 of the one sheet andl in each groove 3 of the adjacent sheet, as best understood from Fig. l, so that, when the two sheets are lapped for a portion of their length, there will be a conveXo-concave portion 4 oppositely disposed in each adjacent space between the ribs.
It will be understood that by formin the conveXo-concave portions 4, the flare o the dovetailed corrugations and spaces will be taken up, thereby removing the dovetailed features of'the spaces and corrugations as best illustrated in Fig. 2, thereby allowing the corrugations to be seated in the spaces as illustrated in Fig. 1, but the relative size between the corrugations and spaces'should be such as lfor instance by making the grooves of slightly less width 'than the ridges so that some spring of the metal is necessary in order to properly seat the alternating corrugations in the alternating spaces. clearly Aillustrated byv the vertical dotted lines in Fig. 2. When thus pressed into place,.,the inherent resiliency of the metal will serve tolfrictionally hold the sheets to- This is iio gether. Inf/use I preferto enter the corrugatlons in the space and afterward so move the sheets with reference to each other that theyl will belapped together for a distance substantially equal to the length of the convexoconca've portions 4, thereby snugly connecting the ends of the sheets together.
In use the cement while in a plastic state is placed upon the sheets substantially as Shown in the drawings, and the cement located between the surfaces ofthe lapped portions of the sheets substantially as shown 1n Figs. 3 and 4. y
It will be understood that the amount of concrete located between the adjacent -surfaces of the lapped portions of the sheets may vary. It will be understood that by providing the conveXo-concave ortions or ribs 4, the rigidity of the sheets 1s increased 'thereby producing a rigi'd joint as between two connected sheets.
It will be seen that by providing the sheet with corru ations and spaces, the sheets are. all sized in special machinery s'o'that the variation caused by the well-known wide variation in the quality of V:sheet steel is overcome by providing the sald ribs in the sheet at the ends of the same.l
be joined together by telescoping the adj oining ends thereof.
, 2. A binding sheet for concrete work comprising a corrugated sheet with the corrugations and the spaces' between them made dove-tailed in cross section, and provided with a central longitudinal rib at one end, whereby .the size or extent of the corrugations at one end is reduced and the spaces between the corrugations correspondingly enlarged whereby two adjacent sheets may be joined together by telescoping the adj oining' ends thereof, said sheet being provided with roughened surfaces.
3. A relnforcing element for concret-e construction consisting of a sheet of corrugated metal, the corrugations and spaces between them being dove-tailed in cross section, each corrugation being provided for a short distance from its end with a rib reducing the width of the corrugations and widening the spaces between them, whereby vadjacent sheets can be joined together.
4. A reinforcing element for concrete construction consisting of a sheet ofA corrugated metal, the corrugations and spaces between them being dove-tailed in cross section, the corrugations having at their ends concavoconvex ribs receivable in the spaces of a juxtaposed reinforcing element whereby adjacent eleinents can be telescopically joined together.
In testimony that I claim the above, I
have hereunto subscribed my name in thel presence of two witnesses.
