REINFORCED-CONCRETE FLOOR CONSTRUCTION.
Specification of Letters Yatent.
Patented J une 30, 1914.
Application filed September 18, 1911.v Serial No. 649,874.
To all 'whom t may concern l y l Be it known that I, WYTHE E. WALKER,
a citizen of the United States of America, county of Salt lindrical hollow centers surrounded by con-- crete which forms in an integral structure both ceiling and joists. Further, to provide in a reinforced concrete floor, a plurality of tubular metal centers, surrounded by concrete, which forms joists between said centers, and a fiat ceiling beneath them, said ceiling and joists being integrally connected` means being provided for temporarily supporting said centers above a temporary fiooring, during the course of construction.
These objects are accomplished by the construct-ion illustrated in the accompanying drawings, in which:
Figure l, is a sectional view of the preferred form of floor construction, take-n transversely of the centers. Fig. 2, isa similar view illustrating a modification in the supporting means for the hollow centers. Fig. 3, is also a sectional view of the floor, showing a style of center adapted for floors of less thickness than those illustrated in Figs. 1 and2. Fig. 4, is a sectional view of the floor taken longitudinally of the centers, the centers being in side elevation. Fig. 5, is a sectional view of aportion of floor, taken transversely of one of the centers, and showing means for temporarily suspending the said centers. And Figs. 6 and 7, are perspective views respectively of the center sup# ports shown in Figs. l and2.
Similar letters of reference'refer to similar parts throughout the several views.
Referring to Figs. 1 and 4 of the accompanying drawings` which embody the preferred form of construction, l designates a temporary floor, which may be supported in any suitable manner. Upon this floor are y secured supports which are arranged in lines or rows at right angles to the usual floor beams. These supports comprisesubstanti ally semi-circular members 2, which terminate at their ends in 'downwardly extending of which the following 1s a- 'I legs'3, having apertured feet 4 at their lowerv ends, through which nails are driven to secure the supports to the temporary door. Thelegs 3 of the supports extend a suitable distance below the lowest pointl of the semicircular bodyrportion v2, vso that when the supports are secured to the floor, as shown in Fig. 1` aspace will be left between the said body portions and the floor, for a purpose to be hereinafter shown. Upon the supports are laid tubular centers 5, which may be made of any suitable material, but which are preferably in the form of semifcircular sheet metal plates, pairs of which are bolted together along their edges as shown, to form tubular sections, which are placed in line upon the supports, with their ends abutting` a number of sections being employed i-n each row, to form a center of the required length. Each tubular section is preferably made of two semi-circular plates, in order that the plates may be nested, so that they will take up less space in transportation, and thus be more easily and conveniently handled. Between the centers are placed the usual reinforcing rods 6, which are spaced about the same distance above the floor as the centers. The centers may be held down upon the su ports in any suitable manner, but preferably by wires 7, which are passed over the centers and secured at their ends to the supports, as clearly shown in Figs. 1 and 4. After the centers have been secured, the concrete 1s applied, and being in liquid form, not only fills the intervening spaces between the centers, but the space be: neath them and the temporary floor as well, thus forming in one integral structure, joists 8 and a flat ceiling 9` thereby dispensing with lathing of any kind. In constructing a floor twelve inches thick, centers of a diameter of ten inches arel preferably employed, and they are supported about inch above the temporary floor, the concrete extending approximately l'inches above the centers, the thickness depending upon area of concrete requiredv to resist compressive stresses.
' The usual floor sleepers-not shown-are placed upon the concrete at right angles to the centers, and the spaces between them are lled in with usual method employed. When the concrete has become suiciently hardened or set, the temporary door is removed and the usual thus arranged andcement, this being the n finishing coat of plaster is applied to the ceiling, the nails which secure the supports to the temporary oor having first been bent to one side or brokenvo. The centers become a permanent part of the licor, and are -in compression with the arched portions thereof,vwhile the joists are maintained by tension of the reinforcing rods i6.
ln Fig. 2', is illustrated aform of center 10, which is also made up of tubular sections, each of which is formed of two semicircular plates. But in this construction, one edge of each plate is' given an l.shaped bend along its length, the bent portions eX- tending ,in opposite directions, when the plates are secured together as shown, so that their stem portions 11 abut or lie back to back, while their base portions 12 rest upon the temporary Hoor. rlChese centers are supported upon triangular plates 13, having right angled members, which rest upon the licor, and overlap the base portions or flanges 12,l of the center sections, This construc tion does away with the use of the wires 7 for holding the centers down when' the concrete is applied.
lin Fig. 3, a style of center is used which is especlally adapted for thin vfloors. In
this case the center sections are made up, of
two plates, thel upperv plate llt being substantlally seml-circular in cross section, while the lower plate 15 is in the form of a shallow V, the supports 16 being of a corresponding shape to receive them. In other respects, the door is constructed in this instance as in the manner before describedn ln'the construction shown in Fig. 5, lthe centers are similar to those shown in ligs.
. 1v and Ll, but they are suspended from in- 40 v verted U-shaped supports 17, in any suitable manner, ypreferably by wires 18, which are passed under thecenters and their ends secured to thevtop of the support. Upon a support of this character, boards may be placed, if desired, to provide a wall: for
.the use of workmen, during the construction of the oor.
I preferably employthin sheetmetal centers, as in some instances the cost of -tile centers is prohibitive, but my invention con- -templates the use of a tubular center made of any suitable material, supported above a temporaryfioor, which permits the concrete to form a ceiling and joists which are integrally connected, dispensing with the emp oyment of any other material in formingthe ceiling.
I Vwish it to be understood that variations of shape. of the hollow centers are included withinvthe scope of my claim, as long as.
such changes are within the spirit of my invention., Y
' Having described my invention, what l claim as newand desire to secure by Letters Patent, is:
In a reinforced concrete floor construction, hollow cylindrical members surrounded onl all sides by a' considerable thickness of concrete; supports for said members having bases ush along their bottom edges with the undersideyof the iloor,-,said bases having a; length approximately e ual to that of the supporting surfaces of vt e supports, and ties encircling the cylindrical members and connected to said supports. f or holding the `members to the supports. In testimony whereof I aliix my signature in presence of two witnesses.
