To all whom it may concern:

Be it known that I, NICHOLAS C. NEWERF, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Concrete Building Construction; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specifi'ation, and to the figures and letters of reference marked thereon.

This invention relates to concrete building construction, wherein the walls, floor and roof are monolithic, the objects of the invention being to provide a structure which is effectively reinforced by metal framing, reinforcements, etc, incorporated in the completed walls, floors and roof, which framing and reinforcements are also utilized during the construction of the walls, floors, etc., as

the means whereby the concrete, while in a plastic condition, is retained in its proper form and as the means whereby the hoisting and conveying appliances and scaffolds are supported during the construction of the walls, floors and roof.

In carrying the invention into practice it may be stated generally that the metallic reinforcements for the walls, etc., are composed of major verticals or columns adapted to be incorporated in the walls at salient points to serve as abutments to support T-joists and rafters. Transverse wire ten sion members are fastened to the abutments and combined with intermediate vertically arranged reinforcements or rods of less diameter and strength than the major reinfor-cements, but adapted to unite the transverse reinforcing members and to afford increased strength between the major reinforcing members. All of the said vertically arranged reinforcing members are adapted to support and carry foraminous sheets or netting reinforcements which primarily constitute the forms for giving shape to the walls, but through which the plastic comositions exudes and is adapted to be finished by tooling to incase or incorporate the netting within the walls and to give a flush to the surfaces. In practical operations, in accordance with the invention, it is also designed that the walls can be made solid, hollow or cellular and that the forms for the cavities shall be composed of relatively heavy paper or paper board suitably stayed and supported within the netting 1 is a detail elevation of two columns and a connecting beam. Fig. 2 is a perspective view showing the upper end of one of the major reinforcements or columns with a girder or joist secured thereto and a rafter for a pitch roof supported by the girder or joist. Fig. 3 is a perspective view of the forms and reinforcements as arranged for the reception of the concrete mixture in a .flat wall of a building having window and door openings therein with gable or 'V-Shaped transom openings over the win- .dow and door openings. Fig. 4 is a detail horizontal section showing the reinforceiments, netting forms and hollow forms for a section of wall, the plane of the section lbeing through a window opening. Fig. 5 is a similar view with the c'oncrete of the walls. in place and the exterior surfaces tooled or finished. Fig. 6 is a perspective view showing somewhat more clearly the way in which the tension and reinforcing and outer form members are assembled on each side of window and door openings for a section of wall to be completed at one time. Fig. 7 is a perspective view showing a section of one corner of a building with the tension reinforcing members for a ceiling and floor prior to the application of the forms or concrete mixture thereto. Fig. 8 is a sectional view through the same show ing the netting support for the concrete coiling slab secured on the tension members. Fig. 9 is a similar view, but with the concrete in place, and a hollow arch formed and temporarily supported by a permanent impcrforate arch form located within the body of the floor. Fig. 10 is an elevation, and Fig. 11 is a transverse section through. a silo embodying the present invention.

In accordance with the present invention, and as illustrated in the accompanying drawings, the major reinforcements or 001- umns referred to in the foregoing preamble, are indicated at A. They are of U-shape, one of said columns being located at each corner, as shown in Fig. 1, and also at suitable intermediate points, preferably seven to eight feet apart or wherever necessary as,

for instance, between the window and door openings as shown in Figs. 3, 4, and 5. Said columns are connected by horizontally arranged. joists preferably of T-iron, as shown at B in the drawings, said joists being supported from the columns by L-shape brackets C.

In preferred construction, the number of horizontal joists or T-irons correspond to the number of columns and are placed so as to be conveniently utilizedwith the columns supporting the floor arches. The ends of said joists are allowed to project 'a suliicient distance beyond the plane of the walls, as shown clearly in Figs. land 3 to form the supports for the "scafi'olding and the concrete conveying apparatus by which the concrete is elevated to the desired height and carried around the points where it is to be deposited in the walls and on the floors. When the construction of the walls has progressed to a point where the projecting ends may be dispensed with, the said projections are cut ofi and the ends of the body incorporated or covered in'the wall. At the ceiling line of the top story, however, the projecting ends of the joist are not removed but serve as the supports for the eaves or subjected to strain by the. transverse tension members to be presently described, and to have sufiicient rigidity vertically to temporarily support the framing above the portion of the wall already completed. together with the concrete conveying apparatus not shown.

Transverse wires or tension members E are drawn tightly between and secured to the outer sides of the columns'A, said transverse wires or tension members being preferably located or spaced apart a suflicient distance to afiord adequate support for fine mesh wire netting forms which are subsequently secured thereto, thus in the illustration of the invention the said wires or tension members are located approximately eighteen inches apart and to properly space and unite them together and afford additional intermediate reinforcements, vertically disposed and relatively heavy metallic rods F are arranged at suitable intervals in proximity to the outer faces of the walls but in position for the fine wire netting forms rac ea G to be supported thereby, if necessary, by being bound thereto, although in the referred arrangement additional intermediate transverse ties H are extended through the wall space from the inner to the outer tension members and serve not only to hold said tension members against the vertical reinforcing rods, but also to retain the wire netting form against outward deflection when subjected to. pressure from the plastic wall material. As many of these transverse ties H may be employed as is necessary to keep the faces of the forms in their proper planes and, if desired, additional short rods or wire may be employed at any desired point, as indicated, for instance at F in Fig. 6. y

In order to support the transverse tension members at the inner faces of the walls without the necessity of employing major columns in line therewith, the tension members E for the inner face of the wall may extend through the walls at the end of the building and be attached to the rods F on the outer faces, as indicated, for instance, at E in Fig. 1, although as an additional sup port and strengthening means, the vertical rod 15" at the inner corner of the wall is anchored by diagonal ties i to the column A. -With this construction, when the transverse tension members and ties are tightened or drawntaut they will present an exceedingly rigid structure well adapted in connection with the vertical rods and columns to support the wire netting forms for giving shape to the outer faces of the walls and for supporting the inner forms which give shape to the cavities or hollows within the walls. Braces, such as indicated at F in Figs. 1, 1 and 2 between columns will be employed for giving additional strength to said columns, and rods in outer part of wall which cooperate with them and thereby give support to the inner tension members, and rods. Rods on the outer part of the wall, not in the way of buckets carrying concrete, can be carried up one story at a time and cooperate with said brace memtioned at each story so as to form a solid, rigid support for the rods and tension wires. Braces 1F extend through the wall to support the rods at the inner side of the wall so that. the whole will be one permanent and rigid structure, as shown in Fig. 1. Obviously, the vertical rods or reinforcing members may be made in sections and united end to end, as by sleeves or split collars I and thus it becomes'unnecessary to provide rods of great length; in fact, the rods may be only of a length equal to the height of. a section of wall to be completed at-one time, say three feet as shown in Fig. 6.

Conveniently, the vertical rods F are located in such position that they will be at the corners of window and door openings,

as shown in Fig. 3, with which arrangement it becomes entirely practical to provide wire netting in lengths which may be drawn or wrapped around the vertical rods and columns, the said netting being of proper width for a depth of cement or con crete which it is desired to add to the wall at any one time. For instance, the netting may be of eighteen inches or three feet wide or high and, while this nettingis being wrapped about the vertical reinforcements to make the forms at one side of the building, a previously prepared portion of the wall on the other side may be filled with cement or concrete, the rocesses of placing the wire netting and filling the same being alternately performed at each side of the building under construction.

At the top of the windows it is preferred that a gable or inverted V-shape transom opening should be,formed and for this pur pose diagonal reinforcing rods K, Fig. 3, are secured to the rods and taut tension members. These diagonal rods form the supports for the wire mesh or netting constituting the bottom of the form on which the concrete above the Window opening is placed. Below the gable transom opening a slab of concrete is preferably formed within a trough-shape section of the netting form indicated at K in Fig. 3, although this feature may be varied in accordance with the ideas of any particular builder or designer.

The. forms for giving shape to the cavities or hollows within the Walls are, as before stated, preferably made of relatively heavy paper or paper board. They may be of any desired shape transversely, but in order to afford the greatest resistance to crushing strains tending to collapse the same, they are preferably angularly arched from edge to edge or have faces which are supported by each other at the edges so as to resist inward pressure.

When located in the walls the internal forms are stayed and supported by the stays between the tension members or netting, although they are also designed to rest one upon the other vertically in the wall, so as to form continuous hollows extending from top to bottom. of the walls. By making these internal forms of heavy paper or paper board. they are cheap, easyto make, light to handle and may be left in the wall without increasing materially the cost of the wall and without leaving material therein which will be a detriment to the completed structure. It will be understood that when the concrete is placed within the. wire netting forms and paddled rather than tamped, a certain portion of the plastic material will pass through the meshes of the netting and, in. accordance with the present invention, as this material passes through the meshes of the netting it. should be smoothed and spread about by hand tools or trowels so as to give form and surface to the outer face of the Wall. Art. the points where window and door openings occur the jamb surfaces areappropriately shaped as, for instance, the retaining beads K Fig. 5, may be formed in the window opening and a snllicient body of the plastic material is accumulated on the outer side of the netting to completely embed and incorporate the netting within the wall itself and to permit of a true plane surface being formed for the'wall faces.

At the floor line, it is designed that tension members shall be drawn taut between the joists B, as shown clearly in Figs. 7, 8, and 9; In said figures of the drawing, the floor tension members L are conveniently placed over the upper edges of the joists, three feet apart, while the lower or ceiling tension members L, pass under the joists eighteen inches apart Upon and across the lower tension members I place a sheet of fine wire mesh, indicated by the letter N, in Fig. 8, the end of which rests on and in the inner wall of the outside walls. The ends of the sheet are secured to the reinforcing rods at both ends, and on the continuation of said walls and center partition upward the ends of the mesh are left submerged and buried therein. However, before the placing of said wire mesh, as described, the partitions on the floor below are constructed in a similar manner as hereinbefore described with the exception of the hollow or paper form, the mesh being completed on either side of said partition to the height of the ceiling tension members and fastened thereto. The partition is then filled by the buckets traveling above the floor and dumping into chutes that fill said partition.

In supporting the ceiling tension members between the joists the are fastened to rods shown by letter O, in ig. 7, or for supporting them during the placing of the ceiling material they are preferably connected to the rod lettered O on floor above, said rod 0 resting on the braces F between the columns, as shown in Figs. 1, 2 and8, and also resting on center partition of the building.

To form the ceiling slab the tension memhers and sheet of wire netting are arranged as shown in Fig. 8, then the plastic composition is poured thereon and spread about and at the same time the under face or that portion of the material which passes through the meshes of the netting is tr'oweled and smoothed to form the surface of the ceiling. This ceiling slab so formed is allowed to stand for a reasonable time, or until set to a sutiicient degree after which a light arch P of relatively stitf paper board or other inexpensive material is sprung between the joists and at the center it is supported by a OE and their ends bent down, as shown in' Fig. 9, so as to be covered by the final floor coating or surface which is added as a finish to the slab.

lFhe internal forms, both of the cavities in the walls and the floor arch, are preferably waterproofed in order that they may maintain their proper shape and condition when in contact with the wet concrete mixture and the meshes of the wire nettingforms should be of such size that the netting will effectually support the body of the concrete, although a certain portion of the finer part of the mixture will pass through the said meshes and be in condition for spreading and tooling. Obviously, the mixing of the concrete to the proper consistency to suit the particular mesh of the netting is a matter of some importance and should be looked after carefully during the building operation so as to obtain uniform results without liability of the surface sagging or stripping while in a plastic condition. The tension members which extend across the window and door openings are cut ofi' when lhe Walls are designed to be self supporting and capable of carrying a heavy load on the floors, that is to say, the concrete of the walls is simply strengthened but not supported by the metal reinforcements. ln lmildings having only a few stories it is well to complete the whole iron frame as a pre liminary step, but in large buildings pilastors can be constructed in conjunction with and become part of said walls, and the iron frame can be erected one story at a time pr an upper story frame can be set up while the walls of concrete for the lower story are being built thus facilitating construction.

In 'Figs. 10 and 11 l have shown a silo constructed. in accordance with the present invention. A building of this character may most conveniently be constructed with external faces, the major vertical reinforce ments being located in the angles as indi cated at The relatively fine wire mesh and horirlontal tension member V form the support for the outer side of the wall dun ing construction while the inner side of the wall is supported by wire mesh and tension members W drawn taut between inner vertical rods W. The number of rods W may be made sufiicient to permit the inner face of the building to be made substantially circular as shown. Each vertical rod W on the inner side of the wall is tied through. the wall to the major reinforce: ments and tension members on the outer side of the wall. Each section of the wall is made hollow by means of permanent paper forms X. The entrant angles on the inner side of the wall are filled by the concrete passing through the wire mesh and the angles on the outer side of the wall form buttresses to give great strength and stability to the whole structure. Inasmuch as the horizontal reinforcements runaround the building a maximum strength is obtained to resist bursting pressure.

Having thus described my invention, what ll claim as new and desire to secure by Letters Patent, is:
