BUILDING CONSTRUCTION.

Application filed May 19,

` My `invention relates in general to the construction of building walls with poured ooncrete,and to a novel means ioreii'ecting such vconstruction without the use of the external forms now generally employed. y

rlfhe common practice in building walls 'with poured concrete, consists of building temporary externa-l forms of wood and pouring the concrete into `such forms. After the concrete is set sutliciently,f` hard, the forms are removed. It will be apparent that this involves a large outlay for labor'and materials, as the materials, are. usually damaged too much to Vbeused again. i y

According to the present invention permanent members'oi1 the wallalre erected, and the concrete is pouredinlbetween such members, which serve toprovide a suitable form, and the whole is formed into one integral unit. Y v p C Another object is to provide a wall of the hind described which shall be tire-proof, damp-proof, and provide asuitable dead-air space i'or Warmth and dryness. Y

l/Vith the above and other objects in view, which will more particularly appear in the p following speciiication, `I have employed the construction generallyshownfin the ac# companying dra-wings, in Iwhich like numerals oi reference indicate similar parts throughout the various views, and in which,

shown one style of my invention, as applied poured into the space formed as hereinafter described. Upon the foundation 1 I have erected two groups of suitable channel irons, as 2 and 3, suitably spaced, andheld in such spaced relation by Ameans of thetie barsy or In the accompanying illustrations, I have 1926.- Serial No. 110,168.

rods 4,` 4 which may be flat pieces of metal, with holes bored at either end and adapted to be attached to the channel irons by nails or wires, as shown at 17. in Fig. 1, or may be suitable rods or wires as4, 4, which are the preferred form, inwhich. case the bent ends are placed in engagement with suitable holes in the channel irons, and the ends of the rods ybent to form permanent connections therewith as shown in Fig. 2.

At a suitable elevation from the bottom I usually place temporarily a two inch timber as ,between lthe channel irons 2 and 3,

`restingV said timber upon ` temporary tie rods 4,4 for a temporary, support, and to this timberl I attach suitable braces as6, 6 to hold thesaid channel irons in perpendicular position until a portion of the wall has been completed. When the construction of the wall has reached a point where it is convenient, this timber may be removed from the posi-- tion shown, and may then be inserted at the top of the channel irons, as shown in Fig. 2. When the wall is completed, this timber is usually embeddedin the concrete at the top of thewall, betweenthe channel irons, to form a' plate, tok which may -be attached the ceilingjoists, or other portions of the frame superstructure." On the exterior,- side of the row ofchannel irons 2, Ihave attached suit` able expanded'metal lath, `or wire mesh 7, which may be attached to the channel irons 2, 2 by means of the tie wires 8, 8, or any scribed, by means o the additional braces 9, `9, which pass aboutthe channel irons ,2, 2, andengage the metal lath at some distance from thepoint of contact with said channel irons 2, 2. On the interior side of the wall` and of the channel irons 3, 3, I have preferablyattached the metal lath,` or suitable wire t mesh, as 10, 10, which said metal lath islattached to said- channel irons 3, 3 by means of Wire `ties,f as 11, 11, or other suitable means, and is additionally strengthened and stiffened by` meansof the additional'braces 12,12, which are attached to the channel irons as shown, and engage the wire mesh or metal lath as shown` at some distance from the contact between said metal lath and the said channel irons. f

Between theuprightrows of channel irons "2,.and 3, I have provided a waterproofinf sulating'N member, 13, placed adjacent the channel irons 3, 3, as shown. This insulat ing material is usually supported temporarily upon the tie rods 4,y 4 which pass therethrough, and said insulating material is extended downward to about the height of the top of the floor joists as shown in Fig. Portions of insulation or other suitable material may be placed between the insulating material 13, and the metal lath 10, intermediate the channel irons, if desired, as shown at 18, for the purpose of supporting the insulating material 13 against the pressure of' the poured cement which is placed against said insulating material, as hereinafter` described. Suitable wall plaster, or other plastic material is placed upon the metal lath 10 in the usual way to form the inside. nish of the wall, as 14. This may consist ofl one or more coats, as preferred bythe architect. Upon the exterior of the wall upon tliemetal'l'ath is placed stucco, or other suitable plastic material 19, for the outside finish of the4 wall', and this said finish may bein one coat, or may be in several coats, as desired.

Into the space formedrbetween the insulating member 13, and the metal lath 7 with the stucco thereon, forming the exterior of thewall, is poured concrete as 23, to form a solidconcrete wall, embracing said insulating material, said tie rods 4, 4, said channel irons 2, 2 andI cemented to the clinches on the interior side ofthe metal lath 7 formed by the stucco placed thereon, forming one solid wall, re-inforeed by the channel irons 2, 2, the tie rods 4, 4 and the metal lath 7. As theV insulat'ingmaterial 13 extends downward only to the top of the floor joists, this leaves an' opening or space formed by the boxing 16, andthe concrete poured in from above as above described, iills said space between' the floor joists and said boxing 16, thereby holding the joists '15, 15 in position,

p and ,closing all openings, making said construction rat andvermin proof. As Wlll be readily seen, there is formed by this construction a dead air space 24 between the insulating material 13, and the wall formed by the metal lath 10 and lthe plaster 14 thereon, thus providing a means of'resisting heat or cold, or dampness, as required.

At the cornersy I have preferably employedan. angle' iron at theoutside as shown at`20, Fig. 1. This angle iron maybe embedded in the concrete foundation 1' as it is being-erected, and when suitably plumbed, will' furnishsuitable lines for erecting the channelirons 2 and 3 between said corners.

This angle ironl is suitably tied to the intey rior corner by thetie wires 21 21, as shown, and the corner construction 1s additionally .re-inforced by, placing Wire 22 midway between the channel' irons 2 and-3 at said corners, Ito re-'inforce saidy corner and preventy cracking or, breaking of theconcrete wall at the corners.

Suitable openings are left for the windowsv and doors, which may be of factory make, as usual. for doors and windows may be of angle irons, or I-beams, as in brick, or tile construction as at present employed to make the wall fire-proof.

As my construction eliminates all wooden forms,and the labor and expense of the materials, it will' be apparent that it is much more economical than the former methods employed. Again, the materia] and parts placed in position, form a permanent part of the completed wall, and assist in reinforcing said wall, and making it stronger and less liable to crack or be damaged than would be the case with a wall notso rcinforced. It will be further seen, that my construct-ion contemplates a completely iinished wall, when the work is finished, with no parts to be altered, changed or removed. It is contemplated in erecting my said concrete wall, that after the channel irons, and wire lathv and insulating material is in place, the stucco masons on vthe outside, and the plasterers onl the inside shall start a course around the wall, and when these courses are suiiiciently set, the concrete workers begin pouring the concrete to form a like course, and follow the direction of the masons around the building. When the masons and plasterers have completed their first course, the concrete workers will be out oftheir way, andthey can apply a second course, and thus theworkers follow one another around the building, laying course on course, untilthe wall is fully completed.

` Having thus described my invention,what I ela-imy and desire to secure by Letters Patent, is the following 1. A form for concrete wall construction comprising upright channel irons, metal lath attached to said channel irons, plastic material upon said metal lath, insulating material between thecourses of channel iron adjacent the inner course, concrete poured into the space formed between the metal lath on'the exterior of said fall. and the insulating material, and a top plate of a width equal to the space between the channel irons and adapted to be guided by the same in the construction of the wallv and embeddedin the. plastic material at the top of the wallbetween the said inner and outer channel irons.

2. ln building-wall construction, the combination of a foundation, inner and outer groups of uprights spaced in parallel relation Aand mounted upon the foundation oor joists supported upon' the foundation at the inner group of uprights, metal lath on exterior and interior sidesof said uprights, an` insulating material mounted on' the If it is desired, the lintels lin ' inner group of uprights at the inner face thereof in spaced relation with the adjacent metal lath and spaced from the foundation to provide an opening to permit concrete to flow between the joists, and Vertical boxings arranged between the joists and extending upwardly from the foundation and confining over the foundation the plastic material flowing between the said joists.

3. A wall forming construction comprising spaced concrete, retaining elements consisting of insulating material on one side, a

metal lath covered with plastic material on the other, said elements being supported by suitable upright `channel irons and approximately V-shaped ties fitting against the channelV irons at the inner faces thereof and having diverging side portions extending to said metal lath to hold the said elements firmly against the. outer faces of the channel irons and forming permanent parts of the complete wall. v

In testimony whereof, I have hereunto affixed my signature, as required.
