Patented Nov. 5,y 1929 UNITED ySTATES f PATENT oFFICE f ROY v. YnAGnn, or `Das MOINES, Iowa `STRUCTURAL FLooIt n Application filed March 13, 1.928. ISerial ,110.261,209.
5 may be laid between the joists, to temporarily of the jeist with support the concrete floor above the plaster joists until the same has set and become bonded with the board and the and hardened plaster board.
The object of my invention is to provide a structure of this character which may be readily and quickly produced by the use of inexpensive materials that can be obtained in almost any locality, and in which the strains upon the plaster board, which might tend to cause them to break or bend during the process of construction, are minimized; and also to provide a reinforcement for the plaster board which will quickly set and harden and form a strong and durable support to receive the concrete floor; and also to provide a structure of this character in which a minimum of concrete is employed for the floor and yet the finished floor will have the same strength as thougha greater amount of concrete were used.
My invention consists in the construction of the floor, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:
Figure 1 shows a vertical sectional View through a portion of a floor embodying my invention; and
Figure 2 shows a vertical sectional view of same on the line 2-2 of Figure l.
Referring to the accompanying drawings, I `have used the reference numeral 10 to indicate a structural joist. Formed on the sides of this joist, between the upper and lower chords thereof, are shoulders at 11. These may be formed in various ways, but as illustrated herein they are formed by a body of gypsum 12 moulded around the body portion the top surface thereof flat to form these shoulders.
When two adjacent joists are placed, then the operator places a. sheet of plaster board 13 between the joists with the edges of the plaster board resting upon the shoulders 11.
ygypsum upon the places a quantity of plastic l plaster boards and surfaces it will be relatively thick in the Then the operator it off, so that center and tapering toward the ends of the y plaster beard, as shown at 14 in Figure l.
57"' Before the gypsum 14 is applied, a series 0 ofL reinforcing rods 15 is placed upon the top chords ofthe joist and permitted to sag downwardly above the central portions of the plaster boards 13, as shown in Figure 1; and also 60 longitudinally extending rods 16 are provided and placed upon the tops of the rods 15.
This plastic gypsum has the quality of quickly setting and hardening, and since a relatively small quantity of it is used, and it 65 is of lighter weight per cubic foot than concrete, it is obvious that no great strains are applied to the plaster boards during the time the gypsum is being applied. Then when the gypsum sets and hardens, which takes place 7o in a few minutes, a temporary floor has been provided which has a considerable degree of strength, because the gypsum is braced by the reinforcing rods and the gypsum becomes bonded to the plaster board.
As soon as the gypsum has become set and hardened, the concrete floor may be laid, and this is done in the ordinary manner, and the temporary iioor formed by the plaster board and'gypsum is sufficiently strong to permit so the workmen to walk about upon the temporary Hoor while the concrete is being' poured or surfaced. The concrete floor then becomes bonded with the gypsum and is reinforced by the reinforcing rods in the ordinary manner.
The completed floor of substantially the same thicknessI as ordinary reinforced Concrete floors, but it is less weight on account of the presence of the lighter material, gypsum. However, it has substantially the same strength, because the floor from one joist to another is of the arched structure commonly employed in bridges and culverts.
By the term plaster board as used herein, I refer to the ordinary building boards of various types and materials now in common use, whether actually embodying iny their construction a plaster or not; and by the term gypsum as herein employed, I do not ldesire to be understood as limiting myself to the so-called pure gypsum7 but refer to a quick setting plastic composition of any cliaracter.
I claim as my invention:
An improved tioor construction, comprising a series of joists spaced apart, plaster boards supported by the joists between the upper and lower ends thereof and covering the spaces between two joists, reinforcing rods resting upon the tops ot the joists and sagging downwardly to position adj aoent to the plaster boards at the central portion of the space between two `ioists, a layer of gyp- 15 sum placed upon the plaster boards and tapered from a maximum thickness at the center between two joists to a minimum thickness adjacent to the joists, and surrounding said reinforcing rods, and a top layer of cement completely enclosing the upper ends of the joists and the reintorcing rods supported thereby and forming an arch shaped reinforced concrete slab between the joists, substantially as and for the purposes stated.
Des Moines, Iowa, March 5, 1928.
