CONCRETE CONSTRUCTION.

Application led February 19, 1923. Serial No. 620,103.

To all whom 'it may concern.'

Be it known that I, ALBERT ORLAN DoL- soN, a citizen of the United States, residing at Imperial, in the county of Imperial and State of California, have invented a new and useful Concrete Construction, of which the following is a specification..

This invention relates to improvements in building wall constructions.

"An object of this invention is to provide an improved building wall construction in which there are inner and outer spaced walls forming a type'of hollow wall, and between whichconcrete beams and columns may be poured.

Another object of this invention is to provide a slab which can be usedv in constructing al hollow wall and which will enable concrete'beams and columns to be poured in the hollow wall. l

With the foregoing and'other objects in view which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanyin drawings for an illustrative embodiment o the invention, wherein:

Figure 1 is a sectional view in plan of a portion of the wall of the improved construction', and may be considered as taken upon the line 1 1 of Fig. 4,

Fig. 2 is a vview similar to Fig. 1, the inner and outer walls being shown as spaced apart, illustrating the manner in which the slabs forming the walls are assembled,

Fig. 3 is a horizontal section taken substantially on the line 3-3 of Fig. 4,

Fig. 4 is a vertical section taken on the line'4-4 of Fig. 1, and

Fig. 5 is a perspective view of one ofthe slabs. Y

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the improved wall is built up of two types of slabs, indicated generally at A and B. Each of the slabs consists of a slab 10 formed of concrete or similar' self-hardening plastic material. A rib 11 is formed on vthe slab in a vertical position at approximately its center, and extends slightly below itslower edge. The upper end of tlijezvertical rib 11 terminates some distance below the top edge of the slab 10. On the slab there are also preferably formed two horizontal ribs indicated at 12 and 13 respectively;v The upper them if so desired.

horizontal rib 12 extends horizontally from the top of the vertical rib 11 toward one 'of the sldeedges of the slab 10. The lower horizontal rib 13 extends from the vertical rib 11 some distance above its bottom toward the same side'edge of the slab 10.` The slabs A and B differ from each other in the following manner. On the slabs A the ribs 12 and 13 lextend from the vertical rib 11 towards the left hand side edge as shown in Fig. 5, while the slabs B havetheir horizontal ribs` extending from the verticall rib 11- toward the right hand side edge of the slab 10Q y j In the vertical rib 11 there may beimbedded one `or more vertical reinforcing rods 14, which reinforcing rods extend upwardly above the upper end of the rib 11. A similar reinforcingl rod or rods '15 may be imbedded in the slab 10' at the back of the rib 11, and these reinforcingrods have their upper ends bent outwardly adjacent the'` upper ends oft-he reinforcing rods 14. Suitable tie' wires arefpreferably imbeddedwin the vertical ribs 11 passing around the vertical reinforcing rods 14. VAdjacent the side edgesof the slabs 10 there' are preferably positioned small rods 16 around which thek t1e` wires 17 may be tied in assembling they Suitable horizontal slabs to forma wall.

reinforcing rods, such as are indicated atV 18, may be imbedded in the forward sides of the horizontal ribs -12 and 13l to reinforce Referring now particularly yto, the vleft hand sides of Figs. 1, 2 and 3 the slabs are i vassembled with the slabs A forming the outer side of the wall and the slabs B forming the inner side of the wall. The vertical ribs 11 upon the slabs B are so arranged as to be positioned opposite the joints between the slabs A, and by this arrangement it will be noted that the upper horizontal ribs 12 upon the slabs A and B extend. completely across the space between'the slabs 10 of the slabs A and B and cooperate to form a continuous beam soffit located below the top edges of the slabs. On this continuous beam soflit suitable reinforcing rods 20 lmay be positioned andV concrete 21 may be poured thereon, thus forming a continuous reinforced ooncrete beam adjacent the upper ends of the slabs, which ties the slabs to-` gether, forming a rigid wall co'nstruction.

In such constructions-the lower horizontal 'rib l'serves very little purposeotherthan being a spacer, spacing the lower portion of zontalbribs formed integral with i said slabs the slabs l() onthej slabs A and l5. However, where there is to be a Window opening, such horizontal ribs may be used to forma lintel. When it is desired to `form a column between the inner and outer walls, the slabs A arepositioned upon the inside so that they form the inside surface ot' the wall. ln .other words where the column space is to occur, as at C, a slab A ispositioned on theinside of the wall so thatits side edge contacts with the side edge ot the slab B, and in a similar manner a slab` B is positioned on the `outside ofthe wall sothat its side edge contacts with the sideedge ot' the slab A. The `wall may be continued to bebuilt in this manner with the slabs B arranged on the outside and the slabs AL arranged on the illsdeuntila next column ispace is desired,.wheretheslabs are aga-in reversed. p'lhisireversal of the positions of the slabs `causes a column space` to beleft between twoadj acont vertical ribs il, which space extends continuously from `topp to bottom `beta/veen theslabs. Suitable reinforcing rods.22 be positioned therein and the concrete 21 used informing' the rein forced concrete beam can bepoured into the column space so as tocompletely `fill it. By

-this construction a column will be oastbetween the iinner ,and outersurfaces of the wall and will be castat the` sameltimethat the beam is pourehlso that it` will be an integralconstruct-ion between the eolumn and the' beam- F rom the above it willlbe appreciatedthat an improvedjtorm ofi construction may @be easily, `quickly :and cheaply assembled, `and that the Abeams andicolumns of reinforced concrete can belpoured between the inner and outer surfaces ofi the walls1 Strengthen ing` it, and servingtoitie or bind the inner Aand outer, slabs together. TVhen the slabs are arranged one course above another, the lower project-ingerida of theyertioal ribs 1l ereresiened en 110,10 ofthe Concrete beam formed between the slabs ot the next `lower course, and this projecting end assumes a position between the upper endsof` the slabs of the `next lower course. Theimproved construction `enables all of the slabs to be `formed ata central plant and shippedto the job where'they are assembled. lt willbe readily appreciated that the slabs may be `quickly placed in'their proper position :and that lAa relatively small amount of concrete .is` requiredtobepoured atthe job in forming; the beams andthe columns.

It `will be understood that various changes may be lmade in the detail of coi'istruction without departing from the spirit orscope of the invention as `deiined by the appended claims.
