Zimmerman, Muscatine, Iowa Application May 25, 1933, Serial No. 672,880 1 Claim. (01. 72-30 This invention relates to walls, partitions, floors and ceilings for residences or other buildings, and also to the various elements of which they may 'be produced and constructed, and

which consists of relatively thin plates of hardened plastic material, asconcrete, or other suitable material, having reinforcing bars which are molded in them at the time of their construction together with improved means for joining the plates together at their adjacent ends; and the invention will be best understood from a study of the following description, taken in connection with the accompanying drawings wherein:

Figure 1 is a perspective view of a partially constructed building illustrating the invention.

Figure 2 is a plan view illustrating the application of the invention in providing a window.

Figure 3 is a plan view illustrating the use of the form provided for a supporting column or beam.

Figure 4 is an elevational view showing the use of the form for pouring a horizontal supporting beam or column.

Figures 5, 6 and 7 are top plan views illustrating some of the various shapes of run-in place plastic beams comprehended by the present invention, and

Figure 8 is a similar view showing a wall structure consisting of but a single step of place and illustrating still another form of run-in-place plastic beams comprehended by the present invention.

- Referring to the drawings by reference numerals it will be seen that 5 designates generally a vertical wall, 6 a flooring, and l a ceiling, all

constructed in accordance with the present invention. The vertical wall 5, flooring 6, and ceiling 1 respectively are made up of pre-cast or formed plates 8 which may be of any suitable size and which preferably are relatively thin.

These plate 8 have reinforcing rods 9 cast therein and the ends of the rods project in reverse direction from the plate at relatively opposite ends of the respective plates as shown. In addition to the units or plates 8 the wall5, flooring G, and ceiling 7 respectively consist of a plurality of supporting columns or beams In which are formed during the construction of the building, and when pouring the concrete for forming the supporting columns ID for the vertical walls 5 a form of the type shown in Figure 3 and indicated generally by the reference numeral II is provided; while when pouring the concrete to provide the supporting beam ill for either the flooring 6 or the ceiling I a form of the type suggested in Figure 4 and designated by the reference numeral [2 is provided, the form being supported by suitable standards [3 or in any other suitable manner. As will be clear from a study of Figures 1 and 3 in forming a vertical wall, such as the wall 5 the outer plates 8 forming the exterior side I4 of'the wall and the inner plates 8 forming the interior side l5 oi. said wall are placed .on edge, in substantially horizontal courses, with the ends in spaced relation and the projecting ends of the rod 9 arranged in alinement and also slightly spaced. (See Figure 3). The plates 8 as before mentioned are precast and, in constructing the wall there will also be provided a suitable foundation or footing l6.

As shown in Figure 3, at the vertical joints I1 between the plates, which joints are opposite each other on the two sides of the wall, are provided the forms I i. These forms may be such as to provide supporting columns 10 of any suitable configuration, however in the present instance I have shown the forms ll being of such character that when the concrete from which the supporting column is formed hardens, and the form ll removed the supporting column will be of substantially I-shape. However, and as willreadily be apparent to those skilled in the art the forms may be of such construction that supporting columns of cruciform shape or of any other desirable shape may be formed.

In the present instance the form ll consists of inner and outer vertical broad fiat boards l8,

-l9 having secured to their inner faces in edge abutting relation pairs of slightly narrower strips 20, 2| and in the present instance I have shown the side of the form constructed of the parts I8 and 20 disposed opposite the joint I! located exteriorly, and the side of the forms consisting of the parts I9 and 2| located interio-rly. Also forming a part of the form II are two intermediate members arranged between the inner and outer facings l4, [5 of the wall at opposite sides of the joint I! and each of these members are substantially U-shaped in horizontal cross section comprising side strips 22 paralleling and in spaced relation to the strips 20, 2|. The vertical edge portions of the side strips 22 nearest to the joint I! are connected by narrow strips 23. In forming the supporting column ill the concrete mix is poured into the form filling the spaces between the strips 20, 22 and 2i and the space between the opposing members 23 so that the resulting supporting column, when the forms are removed will be of the shape clearly shown in Figure 3, in

the present instance substantially I-shaped. Manifestly the projecting ends of the reinforcing rods 9 at the joint I! will be embedded in the concrete of the column I and the columns thereby provide a positive and efiicient joint between the ends of the slabs, .the said column also adding the requisite strength and rigidity to the completed wall.

The flooring 6 and wall I are formed in substantially the same manner as the vertical wall and it is thought that a detailed description of the manner of constructing either would be unnecessary. However, in this connection, and as shown in Figure 4, the form l2 provided for forming a supporting beam in corresponding in shape to a vertical supporting column Ill of the vertical wall 5 differs from the form I l in that the parts I8 and 20 of the form H are not necessary, it, being apparent that the form 12 is disposed in a horizontal position and the concrete mix poured into the form from the top of the fiooring or ceiling as the case may be. As will also be noted in Figure 4 instead of having the adjacent end of the rods 9 being in slightly spaced relation it is proposed to have the rods of each of the plates 8 so relatively spaced as to permit an overlapping relation of the rods for afiording greater reinforcement to the supporting beam I0.

In Figure 2 is shown a corner joint, and also suggested in this figure is a manner of forming a window opening. Shown in Figure 2 the projecting ends of the rods 9 of the corner extend transversely, that is to say the projecting ends of the rods associated with the slabs forming one of the walls extend transversely to the ends of the reinforcing rods associated with the slabs of the other wall and'provide an efiicient reinforcement for the concrete corner beam or stud Z l. It will be understood that the corner studs are formed by providing first a suitable wood form and pouring the concrete mix into the form. In the present instance the form for the stud has been removed.

In said Figure 2 is also shown the manner in which an opening for a window or door may be formed, a stud 25 being carried up on either side of the opening, and in the present instance, the studs 25 are shown as a substantial U-shape in end elevation and it will be of course understood that the studs 25 are formed and poured in a manner similar to that of forming and pouring the beams or columns I0, suitable forms being provided for the forming of the studs. It will also be understood that a suitable form will be placed between the forms of studs 25 so as to permit of the forming and pouring of a plastic sill 26 which of course will extend from one stud 25 to the other stud 25 as shown.

From the foregoing it will be seen that in accordance with the present invention a vertical wall, a flooring, or a ceiling is formed by first laying the precast reinforced plate 8, next arranging at the joint between the plates temporary forms such as the forms II or [2 and the forms then filled with a plastic material such as concrete for providing the supporting beam or column l0. Such obviously provides for the con- 5 struction of a building in a comparatively short time with a minimum number of men and without sacrificing strength and durability.

In Figures 5 to 8 inclusive are shown the possible variations in shape of the columns or runin-place plastic beams l0, Figures 5 and 6 show,- ing such. beams to be in the form of a Maltese cross, while Figure 7 shows such means as being substantially rectangular in end elevation while Figure 8 shows such beams being of substantial l5 T-shape.

In Figure 8 is also illustrated an application of the invention in forming a wall from a single set of plates 8 as distinguished from the walls consisting of two sets of plates spaced apart as illustrated in the other figures of the drawings. In this connection it may be further stated that it is in no wise intended to limit the invention to the construction of a wall including either one or two sets of such plate 8 since within the purview of the invention the walls consisting of three or any other number of sets of such plates 8 may be constructed.

It will be further noted that forms of the type shown in Figures 3 and 4 may be used regardless of the desired shape of run-in-place plastic beam to be used, the necessary rearrangements of the parts of the forms being thought apparent to those skilled in the art.

Having thus described my invention, what I claim as new is:

A building construction consisting of a plurality of plastic plates arranged in two sets spaced apart. each set of plates comprising a plurality of plates disposed with the vertical ends thereof in relatively spaced relation, the plates of each set being also arranged in superimposed horizontal courses, the joints of one set of plates being oppo site those of the other set of plates; reinforcing members extending through said plates and projecting from the ends thereof into the space provided at said joints, said reinforcing members being straight from end to end, with the projecting ends of the reinforcing members of one plate arranged in alternate relation with the projecting ends of the reinforcing members of the next adjacent plate, and also being arranged in substantially the same plane therewith and runin-place plastic beams at the joints between the plates, each of the beams having portions thereof arranged in the spaces between the ends of the plates and embedding the projecting ends of the reinforcing members, each of said beams also including a part arranged in the space between the two sets of plates, each of said beams being of substantially I-shape.
