HOLLOW FIREPROOF WALL CONSTRUCTION.
Application filed March 24, 1924. Serial No. 701,346.
' To all whom it may concern:
Be it known that we, l/VARREN Z. Arnns, lilnunicn E. THORNTON, and WILLIAM T. H. AYERs, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Hollow Fireproof Wall Construction, of which the following is a specification.
Our invention consists in a novel wall construction comprising two sets of relatively thin slabs laid up on edge in courses with studs intervening between the two sets of slabs and being poured in place of concrete such that the pouring of the studs results in a unit wall with the slabs keyed and united to the studs. The primary object of the invention consists in providing a hollow wall construction built up of light, standardized slabs, such that the wall may be erected so as to eliminate the usual wooden forms required for the entire enclosure of the wall as a mold, and so eliminate their high cost of production in labor, material, and time. The time element in construction work is most important and with the use of our construction, a wall may be erected to completion far quicker than the time consumed in building a form otherwise necessary for a corresponding wall.
Further objects lie in the provision of side slabs of such proportions as to permit of the breaking of joints or bonds of one set of slabs as compared to the other set on the opposite side of the wall, thereby reinforcing and stillening the wall longitudinally; a versatile and flexible construction permitting any width of wall by merely us ing different width stud molds, and easily cut and adapted to openings and corners; and simple shaped slabs that may be molded on the job and set up in the wall without waiting for a long curing period, such slabs havingtheir edges so formed as to permit easy removal of the slab mold form and to give retaining edges for the slabs when set in position in the wall as well as to form a means of securing a key or clinch of concrete. I
We accomplish these and such other objects as may become apparent in the following description by the means as shown in the accompanying drawing, in which- Fig. 1 is a perspective View of a fragment of a wall of our construction showing the studs in various stages of formation; F ig. 2, a side elevation of an outer face of a standard wall slab; Fig. 3, a similar wall slab, showing a possible variation by pro viding notches for additional keying; Fig. 4-, a vertical section through the slab on the line 4L-4 in Fig. 2; and Fig. 5, Fig. 6, and Fig. 7, perspective views of ties, showing modified ends, employed in holding the slabs.
Like characters of reference indicate like parts throughout the various figures.
The unit of construction is the slab 5 formed of concrete in a suitable mold, though it may be made of tile or similar material, and for the purpose of forming a base to which trim may be secured, cinder concrete may be employed as there is no building load taken by the slabs. The slab 5 is relatively thin as shown in Fig. d, and has the top edge bevelled to bring the sharp edge at the outer face a, and the lower edge bevelled to form the sharp edge at the inner face I). The two ends are bevelled from the inner face 6 to the outer face a such that when the slabs are butted together a V is formed between.
The slabs 5, Fig. 1, are laid on edge in courses to break joint as in laying brick, to form an inner wall 6 and an outer wall 7 such that an air space lies between. As the two walls are laid the courses are kept at the same level, the lower bevel edge of the slab above fitting on the top bevel edge of the slab below, such that the lower edge of the upper slab can not kick or slip outwardly. To prevent the top edges of the slabs from pushing outwardly and to maintain the two walls in alignment, we use ties 8, 9, or 10 (any one being equally suitable, but here shown in Figs. 5, 6 and 7 to illustrate the variety of ties in suitable form) across the top edges of the slabs. Small notches are chipped out of the slab to permit the placing of the ties down out of the way of the above slab edge. Particular emphasis is desired to be placed on the fact that the center of one slab 5 in one wall lies across from the abutting ends of two slabs 5 in the opposite wall in the same horizontal course level such that the joints are staggered in the opposite walls for the purpose of stiffening the wall as a unit.
The key 15 is at first rough as the key formed when plaster is forced through lath, but may later be filled in or smoothed off as desired. The slabs 5 are set up without mortar between any of the edges and are permanently retained in position by knitting to the studs 18 and the keys between the abutting edges, and somewhat by the ties 8, though these ties are primarily temporary means of holding the slabs until the studs 13 are poured and cured.
lVhen desired, the slab as shown in Fig. 3, with the lower edge supplied with stud notches 16 and 17, may be employed to give a larger key over the studs by reason of the increased openings presented on account of the end notches l6 and center notch 17 in the lower edge out on a bevel to give a retaining edge for the key. It will be noted that this type of slab permits a key in the center of the slab where it contacts the stud 13 as well as on the ends of the slab.
Plaster or stucco may be applied directly to the face of the wall of slabs for a finish. The slabs being made of concrete or the like, fit together roughly on their edges so as to leave small interstices which form means of keying the finish plaster or stucco to the wall.
Having fully described our invention in the form now best known to us, we desire to set out that the construction and its units may be varied without departing from the spirit of the lnvention, and we therefore do not desire to be limited to the precise form as shown, nor any more than may be required by the following claims.
e claim:
