AVILA O. THOMAS OF DETROIT, MICHIGAN, ASSTGNOR TO THE STRUCTURAL CONCRETE UNITS CORPORATION, 013 DETROIT, MICHIGAN, A COREPORIFLTION OF DELAWARE UNIT WALL CONSTRUCTION Application filed September 16, 1929. Serial No. 392,945.

This invention relates to wall constructions, and particularly to interfitting wallforming units, precast of concrete or other cementitious material.

An object of the invention is to so interlock and tie together a system of precast building units as to form a rigid, substantial wall such as may be quickly and easily erected, at relatively low cost.

Another object is to form a hollow wall of spaced vertical sectional columns and inner and outer wall plates extending between and abutting said columns, and to extend tie members through the columns to connect said plates. 7

A further object is to form said columns of complementary channel-shaped units, and to utilize said tie members to hold said units securely in complementary relation.

a A still further object is to provide means for quickly inter-connecting a pair of column-forming units in complementaryrelation, preliminary to their assembly in a wall. These and various other objects the invention attains by theconstruction herein-' after described and illustrated in the ac ompanying drawings, wherein: Fig. 1 is a plan view of a portion of a wall embodying the invention.

Fig. 2 is an elevational view thereof.

Fig. 3 is an enlargement of a portion of Fig. 1.

Fig. 4 is a fragmentary, perspective view of a top portion of one of the column-forming units.

Fig. 5 is a similar view of the complementary portion of one of the wall plates.

. Fig. 6 is a vertical cross sectional View of the abutting ends of one of two of the column units, one superposed on the other,

taken upon the line 66 of Fig. 3.

Fig. 7 is a vertical section taken upon the line 77 of Fig. 3 disclosing a connection between two wall plates resting one upon another and showing the engagement of a tie member with one of said plates.

In these views, the reference characters 1 and 2 designate a pair of channel-shaped column-forming units of concrete or the like,

which, preliminary to their positioning in a rods 4.

wall, are oppositely arranged inthe abutting relation, clearly appearing in Figs. 1 and Said units are of a height suited for convenient handling, and a sufiicient number thereof may be set one upon another to build up a column of desired height. Preferably the abutting faces of said units are formed with inter-fitting V shaped ribs and chan-' nels 3 extending the full height of said units to aid in their quick and accurate assembly.

Cast into each unit 1 and 2 is a .pairof metal rods 4:, extending from top to bottom thereof, substantially at the junctures of their relatively transverse portions, acting to reinforce the units and also providing for rigidly connecting superposed units. Thus said rods terminally project into recesses 5 formed in the end faces of the units and are engageab-le within said recesses by couplingsleeves 6 transversing the horizontal meeting plane of the units. 1

A tie connection is established between each pair of'unitsl and 2 at their ends, by a pair of metal rods (or heavy wires) 7, ex tending in the recesses 5 and having their ends looped, as indicated at 8, to embrace the l/Vhen initially set in said recesses, the loops 8 are, open, as appears in dash lines in Fig. 3, said. loops being subsequently closed by pliers or some other suitable tool to tightly hug the rods 45.

. The columnsformed by. the units 1, 2 are suitably spaced, and between the same are extended pairs of spaced wall plates 10, pre

cast of concrete or the like, a suitable numher thereof beingsuperposed one on another 1 to achieve the desired height. Said plates may be set flush with the columns, and their extremities are preferablyformed with positioning ribs 11 coextensive in height with said plates and offset from the outer faces of the latter to fit into channels 12exteriorly formed in the units 1 and 2. It is preferred to reinforce the plates 10 by centrally imbedding therein sheets 13 of a wire mesh or other foraminated metallic fabric, substantially coextensive with said plates.

The ends of the wall plates are tied to the columns by pairs of diagonally crossed metal tie bars 14, arranged between the suimbedded in the bottom portion. of each,

plate 10, and project into the recesses 16. A coupling sleeve lS withinthe communi cating recesses 16 engages the aligned ends of said pins as bestappears in. Fig. 7, there.-

b assurin accurate vertical -re istration of.

the tiers ofmiall plates. The bars lta'etain the plateslO at lopposite sides ofthe columns properly engagedswith the latter, andfurthermore act through. said plates to supple. ment the. tie. rods 7-. in maintainingthe proper abutting relation between the column units land 2.. A

After .the columns. have becnbuilt up to the desired height, theynnay.befilledcwith concreteasappears inEi-g. l-to furtherincrease their. rigidity- The described a construction is simple and easily erected, and its. parts. are. adapted .for rapid machine production. Thetie mem bers are. also. simple. and inexpensive, and may be. rapidlyappliedas each successive tier-ofthe wall .is completed;

The construction is furthermore one that imparts a high degreeofrigidityto the completed .wall, permittingthe latter. to be: safely carried to a. considerable height. andgiving it. substantially all. of..- the advantages of. a monolithic. hollow. wall, while far less expensive.

The invention as exemplifiediin. the. drawings. discloses .the columns as equal in .width to the wall.- Itis, however, to be understood that it frequently. may be desirabletoenn ploy columns of' greater-.widththanthe.in= tervening. portions of the wall, particularly when the columns are. required tov carry heavy loads. Withoutdivergence, fromthe principles illustrated by thedrawings, differe'ntly proportioned; columns .may be em ployedwithout variation in proportions of the illustrated .wall I plates orin the spaced relation of the. paired plates. Eormationof the column-forming units separately. from the, wall plates renders the. several units lighter. and. more, readily handled than 7 would ,be the caseifthe wall plates and column units were. integrated, as wellias per, mitting the aforementioned variation in the column width relative. to the..width.of..the wall proper.

While itis apparent that;theillustrated embodiment of my invention hereindis.- closediswell calculated to adequately fulfill the objects and advantages primarily stated, it is to be understood that the invention is susceptible to variation, modification and change within the spirit and scope of the subjoined claims.
