Application filed May 25, 1926.

This invention relates to and has for a main object the provision of a new and improved type of building construction, partirulaiwy adapted to the construction of concrete buildings and embodying means of arranging and forming metallic reinforcements for the walls, whereby the same may be quickly and economically positioned for receiving and holding the concrete without the necessity of wooden forms, frames or supports of any kind.

An object is to provide a type of building construction in which a well known form of expanded metal lath is employed, and to which and on both sides of which concrete is applied after the reinforcement has been erected.

Another object is to provide a type of building construction embodying a metallic reinforcing material, Vinitially formed in comparatively stiff sheets similar to the metal lath now in use and bent at the eX- tremities at right angles or curved for a distance corresponding to the proposed thickness of a wall, and again at right angles into a plane paralleling the body portion thereof.` Thus the sheets of reinforcing material when positioned vertically will be selfsupporting without the use of frames and suiiiciently rigid to support a wall. Adjacent sheets may be secured together for forming a continuous reinforcement throughout the length` and area of the wall.

Another object is to form said sheet-s of reinforcing material that the bent end portions thereof may be spaced with respect to each other so as to provide an occasional and necessary pier throughout the length of the Wall.

A further object is to provide means supported on the reinforcing material, such as sheets of building paper or the like, and adapted to be substantially spaced from a sheet of material so as to form a backing for and when the concrete is applied to the building material, for the purpose of eliminating the necessity for forms on the rear sides of the reinforcing material.

A further object is to so form and arrange the reinforcing material that hollow concrete walls may be formed around and supported on the reinforcing material so as to provide air spaces in between the two thicknesses of the walls for the purpose of insulating a building against sound, heat and cold.

Serial No. 111,535.

Having `the hereinbefore mentioned objects in view, together with other objects which will appear as the description pro-y gresses, I have shown a preferred embodiment of my invention, with certain minor modifications and adaptations to different purposes, in the accompanying drawings, in which: l

Fig. l is fragmentary sectional plan of and showing particularly the concrete supported on both sides of a sheet of metallic reinforcing element, with a backing of paper spaced therefrom.

Fig. 4 is a fragmentary face view of the same, before the concrete has been applied.

Fig. 5 is a fragmentary section of the reinforcing material with the paper backing supported thereon, before the concrete is applied thereto.

Fig. 6 is a fragmentary section of a hollow` wall embodying my improvements.

Fig. 7 is a perspective View of a section of wall embodying my improvements, partly broken away to show the reinforcing material, and means for supporting the wall on and binding the same to the foundation,

Fig. 8 is a fragmentary section. of a sheet of reinforcing material formed in accordance with my invention.

It will be understood at the outset that it is common practice in building construction to use a wire or metal lath of the character shown herein, to which concrete is applied, but the present practice in building construction necessitates the provision of either temporary or permanent forms, or wood or steel construction for the purpose of supporting the metallic reinforcing material, and it is contemplated in the present invention to provide a system Vwhich will eliminate all unnecessary and expensive framing, forms of wood or steel, in order that the erection of a building by the employment of my improved method inay be expedited and more economical than in other types of construem tion. l

As shown in Figs. l, 2, 6, and 7, a typical wall and one which has a sufficient strength for supporting a building of one to four stories, and at the ,ame time has benelits ot' insulation against heat, cold and sound is a hollow Wall, embodying an inner Wall WV and an outer Wall VJ toi-ined ot' concrete as at C, and sheets ot reinforcing` material as at lt, spaced apart so as to provide a series of air spaces A. etc, between the Wall portions l and W. The inner and outer Walls are connected at frequent oi necessary intervals by means ot' transverse sections or piers, as at l), P, etc., and this type of construction lends itsel'l`l readily to accommodate openings as at O and U for Windows l, and doors 2, respectively.

The reinforcing material ld, as shown clearly and in detail in Figs. 4 and 5, is of the character of the Wire mesh, but is in efiect cut from sheets of iron and stre ched as shown in Fig. Ll. llhen so cut and stretched the material being made of substantial thickness, it provides a very rigid sheet ot material and may be formed in lengths and Widths suitable to proposed types ot construction.

The material R is Well known in building construction, and is made in different sizes and ot ditl'erent thicknesses ot material, the lighter material being designated commonly as metal lath, While the heavier material is designated as metal reinforcement.

As shown in Fig. S, after the material R has been it'ormed into desired Widths and lengths, the sheets ot material are then bent as shown at r, at right angles, or curved forming end portions e, and thereafter bent at 11" inwardly in planes parallel With the sheets ot material B for short distances to provide extensions e. The material may be laid either horizontally or vertically of the sheets, and the bends fr and 7* are made to correspond to the position the sheets are to occupy in a proposed Wall structure.

As shown in Figs. l and 6, the end portions e are bent so as to extend transversely through the Wall, While the extensions e are bent so as to extend horizontally and in parallelism with the body of the material B. lt will be observed that, preferably, only one el the ends or each sheet is bent as shown in Fig. S, and when erected in a Wall as shown in Figs. l and 6, one sheet or' material is placed in the wall W and another in the Wall lV in reversed positions, so that the extensions e may be tied by loops ot Wire or other means, as at 3, to the bodies ll of the rein'orcing material adjacent thereto, the material overlapping at such points. The piers P will be spaced apart to correspond to the lengths of the material R, and each of the piers will be reinforced by two ot the end sections e of the reinforcing material.

is shown in 8. el and 5, sheets ot building' paper or the like. as at l, are attached to the sheets ot reinforcingmaterial lt by means of ivire loops 5, 5, which are bent around the portions 6, 6, of the reinforcing` material, and a plurality ot' said loops are alined through the lengths of said material, in one or more planes, and connected by means of Wires 7, 7 on the rear side of the paper. The loops 5 are ot sutlicient length to space the paper l backwardly from the reint'orcingmaterial tor a sullicient distance, approximating one-halt inch or so.

rlfhe paper il is attached to the material R prior to the erection ot the reinforcing material in the building, and for the purpose et backing, as shown in 5, the paper LlA will closely fit against the sheets ot' material l, but when placed in a building` it is feftretched into position shown in Fig. 3 so as to provide an ample space between the paper and the material R for the reception cit concrete.

The material il. when formed as shown in Fig. 8, may be cut so that the body portion thereof may be of any suitable length to accommodate the material to short Wall sections as shown at the lett in Fig. l, for the purpose of forming window or door openings.

iis shown in Fig. 2, a concrete foundation l" is provided With upwardly extended strips S, 8, etc., alined throughout the length of the foundation, to which the sheets of ma terial hl are adapted to be tied by means ot the ties S3 or otherwise, when the same is erected on the foundation, preparatory to liorming` the Walls fr and lV.

it the top oit each story of a building the sheets ot material R in the inner and outer Wall sections lV and YV, respectively, are connected together by means of an inverted channeled strip 9 ot the reinforcing,T material. ll, which is tied at 3, 8, etc., to the spaced sheets orn material lt, and said section 9 is positioned between and beloiv the upper edges of the sheets of material R so as to provide a beam as at l() of concrete thereabove, for the reception of the ratter ot a roof in the case of a one story building, or joists in the case ot a multiple story building. The same treatment is practiced by forming` the material and the ivalls under and over the Windowv openings O, and over the door openin gs rlhe concrete for the particular type of instruction is best applied to the reinforcenient R by means ot a cement gun which uses a mixture of cement, sand and nf'ater applied by means of compressed air through the nozzle or' the gun., With suitable pressure on the oi'itsides ot the Wall sections lV and l, so that a sulticient thickness ot the concrete will tind lodgment between the paper 'backing` l and the reinforcement R in each of the wall sections, and an additional thickness externally oit the material l?, the air pressure and impact ot the mixture being insufficient to break the paper but sufficient to cause a dense mixture for the wall without forms.

In most cases where concrete walls are used, it is unnecessary to smoothly finish the interior walls, but when it is desired so to do, wooden ground strips, as in usual plastering practice, may be placed on top of the foundation and near the top of the beam l() of the wall, over which a straight edge may be run for smoothing the exposed portion of the wall, though this is immaterial to my invention.

It will be observed, particularly by reference to Figs. l and (i, that shallow wall sections W and WV may be provided with substantially wide air spaces A therebetween, especially for partitions or exterior walls in one storybuildings, or thicker wall sections W and WV may be provided with shallower air spaces where greater strength lis needed for supporting buildings of several stories in height. Also the thickness of piers I), etc., may be correspondingly increased in accordance with requirements.

It will be readily understood that the adaptation of my method to the different types of walls and the requirements for different uses is easily accomplished by cutting or forming the sheets of material R to conform to the thickness, height and length of the wall section and the openings therein, and the several sheets of reinforcing material R may be overlapped to a more or less extent without necessitating cutting the material for increasing the thickness of the piers l).

I have ascertained that by the employment of the system of building construction and the reinforcing material and form thereof as shown herein, it is possible to provide concrete walls of a minimum cubical content of concrete, and a maximum strength, with far less expense and much quicker time than is possible with other obtaining types of building construction and the use of other materials. In fact, I have ascertained that a wall section of the character shown in Figs. 6 and 7 for instance, has a carrying capacity of about two and one-half times that of a solid concrete wall with the usual reinforcement. This is true because in my system of construction it will be noted, I employ continuous sheets of reinforcing material throughout the length of the one or more wall sections, with connecting transverse sections and vhorizontal sections so `tied together at frequent intervals, so that no local section of a wall can be crushed or broken away from an adjacent section under a given strain, or by means of impact in local points.

It will also be observed that in my system of construction the air chambers A may be utilized at desirable or necessary points for the accommodation of water and drain pipes, elect-ric light, telephone wires, gas

pipes, etc, without necessitating special accommodation for these elements, and suitable openings may be made in either the inner or outer walls so as to afford access thereto.

I have shown a preferred form of my reinforcing material as It, the same being readily obtainable in `the market and in common use for other purposes, particularly as wire or metal lath adapted to be used in sheet form and suitably secured to the studs or framework of a building, but it will be understood I may use any suitable sheet reinforcing material of metallic character which is susceptible to the treatment herein named, and for the purpose specified. I may also modify my invention within thescope of the appended claims without departing from the spirit thereof.
