This invention relates to improvements in bullding construction, and the invention has reference, more particularly, to an improved assembly of materials for use in the erection of both exterior and interior walls of buildings of all kinds.

This invention has for its principal object to provide a novel and economical means for producing building walls and partitions of cast concrete, comprising pre-fabricated wall form units capable of being quickly assembled together so as to furnish a form to receive and shape cast concrete into a wall core, said units thereupon becoming a permanent part of the finished wall structure, and having means to support facings of wire lath in spaced relation to the sides of the wall for the reception of stucco or plaster coatings so related to the wall body as to provide intermediate air spaces for heat insulating effects.

This invention has for a further object to provide novel building units capable of serving as concrete casting forms, said units having novel means for interlocking adjoining units in operative assembled relation.

7 This invention has for another object to provide novel building units comprising pairs of transversely spaced apart panels of paperboard or similar inexpensive material, held in operative spaced connected relation by transverse tie-rods, the latter having-threaded end portions projecting from the outer faces of said panels to receive stop and fastening nuts for mounting metal lath sections in spaced offset relation to the outer faces of the panels, whereby, when the units are assembled for the erection of a wall, plaster or stucco coatings may be applied to the lath sections in spaced relation to the erected wall so as to provide heat insulating air spaces contiguous to the sides of the wall.

Other objects of this invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.

I An illustrative embodiment of'this invention is shown in the accompanying drawings, in which j r r v Fig. l" is a side elevation of a wall or partition embodying the novel structural features 1931. Serial No. 530,011.

provided by this invention; Fig. 2- is a vertical transverse section, taken on line 2-2 in" Fig. 1, and drawn on an enlarged scale; and Fig. 3 is a top edge view of a single building unit according to this invention. a v 1 Similar characters of reference are employed in the above described views, to indi cate corresponding parts.

In the construction and erection of a wall, either in the form of all-external wall or an interior partition, building units are first fabricated to be taken to the job for erection. Each such building unit comprises a'pair of side panels. 5, preferably made of stiff comparatively heavy pressed paper or fiberboard, usually approximating from one quarter to three-eighths of an inch in thickness. I have found it feasible to use panels having dimen-' sions of approximately four by three feet, al-

though larger or smaller dimensions may be employed. Said panels are arranged side by side in spaced apart relation, according to the thickness of the ultimate wall or partition desired to be erected. Said panels are tied together by transverse tie-rods 6, which e'xtend entirely through the same, and which are relatively spaced apart at suitable intervals. Said tie-rods 6 are preferably made of round iron of about one-quarter inch diameter, and are provided at their respective end portions with screw-threads. Threaded onthe respective end portions of the rods are inner backing nuts 7, which provide stop abutments to engage the inner sides of the panels 5, so as to position the latter in desired spaced apart relation. The panels are perforated to receive thetie-rod end portions, whereby the latter may project outwardly beyond the outer faces of the panels. Threaded. on the tie-rods are fastening nuts 8 which are screwed home on the tie-rod ends so as to engage the outer faces; of the panels 5, whereby the latter are firmly fixed in stopped relation against said inner backingnuts 7, and thus assembled securely together in de-. sired spaced relation. Adjustably threaded on the exteriorly projecting ends of said tierods are p irs of jamb-nuts 9, which'may be adjusted and locked on the tie-rods in'outwardly oif-set relation to the outer faces of faces of the panels 5. In mounting the metal lath sections 10, the extremities of the tie-rods pass through the mesh thereof, thereby holding the*lathagainst displacement in directions of the face planes thereof. To secure the metal lath against displacement from operative supported relation to the tie rod-extremities, fastening nuts 9 are screwed upon the latter to abut the outer faces of the assembled lath sections.

In one embodiment of my invention, the metal lath sectionspare applied when fabricatingjthebuilding units, in which case it is preferable to inturn-the marginal ,edgesof thelath sections 10 as indicated at 10 in: Fig. 3. If desired,rhowever, the metal lath may be omitted from the fabricated building units, and may be subsequently applied thereto after said units are assembled inerectin-g awall, thus permitting. the use of areas of metal lath greater than theface areas of the individual building units.

The building units are providedwith means to mutually interlock the same togetherwhen a,lplura lity of the same are assembled edge towedge during the course of erecting a wall. The interlocking means comprises female sheet metal;bindin-gelementsll having a longitudinal open receiving channel or groove 11, and male metal sheet building elements IQ'h-aving .a longitudinal-tongue or rib 12. Said female sheet metal binding elements are-fastenecbby-rivets, or any other suitable form of fastening means, to and along the bottom andrear vertical edges of: the respective panels 5, while said male sheet metal bindingelements are fastened by-rivets, or other suitable fastening means, to and along thetopand forward vertical edges of the respective panels. 5.

In the use of the above describedbuilding units,preparatory to erection ofa wall there- With, a;suitable:foun'dation, as 13 (see Figs. 1,and2) is prepared upon which the lower course ofassembled units may be supported. TheL-firstfor lower course of building-units is :mounted on the foundation 13, with the forward and rearvertical edges of the panels 5-. of adjoining unitsinterlocked together by the-insertion 10fthe tongue or rib 12 ofa ma-lesheet metalbinding element 12 of-the one-into-the channel'or-groove 11 of a femalesheetmetal binding element 11 of the other. .By thus interlocking the building units together, thesa-me are held at their verticalsides, rigid and'secure against lateral displacementzrelative onev to the other. The next course of building units is now mounted upon the first course,;preferably in .the staggeredrelation illustrated in Fig. :1 of the drawings. The-second course is rigidly interlocked with the first course by the in sertion of the tongues or ribs 12 of the male sheet metal binding elements 12 at the top edges of the panels of units forming said first course into the channels or grooves 11 of the female sheet metal binding elements 11 at the bottom edges of the panels of units formingjsaid second course, thus interlocking the meeting ed es of the respective courses together, whereby the same are held rigid and secure against. relative displacement at the same time the vertical meeting edges of units forming said second course'are interlocked by the male and female elements at their adj oining 'vertical edges, in the same manner as already described with respect to the units of the first course. continued until a. desired height andlength of wall is, produced. 1

After the erection of-the buildingcunitsin the manner above described, orfrom timetc time as given desired sections thereof me These operations may "be assembled, a wet mixture of concrete is poured into the space between the-spaced apart'panels .5, thus. forming a strong. and

durable concrete vwall core 14. Such wall core will not only be moldedby; theform pro-L vided by the erected building units, :but will also be reenforced by the vtransverse tie-rods 6 against cracking. building. units. remain in place,.,they. serve to shield the concrete core wall, and aid 'in guardingthe same against dis-integration.

After the wall has been: erected, either. to

include the preassemble'd metal lath sections, or to include metal. lath fa-cings applied. during or after completion of. thewall, vthesame is ready to. receive the application of stucco or plaster coatings. If the Wallis: an external wall, a suitably mixed cement stuccov coating; I

15 is applied to. the metal. lath retaining base 10, and since the latter is off-set from the outer face of the-wall, said stucco coating will be likewise spaced therefrom so as'to forman intermediate air space 16 contiguous-and parallel to the outer face of the wall. Such air space 16 provides. a very efficient: heat insulation effectand also assures. a moisture proof and dry inner wall condition.

In like. manner a suitable interior, plaster Since the, panels .5 of the assembled building units and interior concrete core wall.

It will be further understood that the novel wall structure provides a construction of low cost as well as one which may be rapidly erected with a minimum of skilled labor; at the same time a very strong and durable wall is provided, and one having highly efficient moisture and heat insulation.

As many changes could be made in the novel wall structure as a Whole, and in the novel pre -fabricated building units entering into the construction of the same, and many apparently widely different embodiments of the features of this invention could be made without departing from the scope thereof as defined by the appended claims, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
