EDWARD F. NEEDHAM, OF HOUSTON, TEXELS, ASSIGNOR 0F 0NE- IALF TO JAMES DONALD HALL.

WALL CONSTRUCTION.

Application filed August 11, 1.929.

T 0 all whom it may concern:

Be it known that I, EDWARD F. NEEDHAM, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in l Vall Construction, of which the following is a specification.

This invention relates to new and useful improvements in a wall construction.

One object of the invention is to provide a wall constructed of concrete slabs suitably spaced apart and securely anchored together, thus forming a wall which is hollow, which permits the free circulation of air therethrough, which is light and will require a minimum amount of material and which at the same time is of sufficient strength to sustain the strains to which it will be subjected.

Another object of the invention is to provide a wall which is of comparatively simple construction and which may consequently be cheaply and easily erected.

With the above and other objects in view the invention has particular relation to certain novel features of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a perspective View ofa section of a wall, shown partially in section.

Fig. 2 is a fragmentary plan view showing the free ends of the wall slabs and illustrating the method of anchoring them together.

Fig. 3 is a perspective view of a section of a wall, shown partially in section, and partially broken away, illustrating another form of the construction.

Fig. 1 is a top plan view of the wall slabs of this modified form illustrating the method of anchoring them together, and

Fig. 5 is a fragmentary perspective view of the top plate employed in the erection of the form shown in Figs. 3 and 4:.

Referring now more particularly to Figs. 1 and 2, the numeral 1 designates the base plate which is preferably formed of concrete and is carried upon a suitable foundation (not shown). The upper side of this plate has a dovetailed groove 52 therein to receive the lower ends of the wall slabs 3 and 1. The groove 2 is of considerable width and the opposing Wall slabs are set near the opposite sides thereof, and mortar is then poured in plastic state into the dovetailed portions of the groove on the outer sides of Specification of Letters Patent.

the lower ends of the respective slabs and permitted to harden, forming the keys 5, 5.

The wall slabs 3 and 4t have the end ribs 6 extending at right angles thereto, the said ribs 6 of the adjoining ends of the respective slabs fitting together, as shown in Figs. 1 and 2, and extending from the lower end of the slabs near the upper end thereof by falling slightly short of said upper end, as shown in Fig. 1. It is to be noted that the joints between the slabs 3 alternate with the joints between the slabs 1 and the ribs 6 of said respective slabs alternate when the slabs are erected into the structure. It is to be noted that the ribs 6 span the space between the double wall, and it is to be further noted that a section 7 of the free edges of said ribs is cut away forming air passageways to permit the circulation of air throughout the wall structure. At the joints between the respective slabs, vertical grooves 8 are formed which are filled with mortar in plastic state so as to cover up said joints and give a smooth continuous wall surface. This mortar, while plastic, keys into the keyways 9, formed in the adjacent sides of the ribs 6, and when it hardens it is thereby held practically as an integral part of the wall. The wall slabs 3 and 4 are provided at their upper ends with inwardly extending lugs "10',"10- and 11, 11, which embrace the adjoining ribs 66f'the opposing slabs. Between the adjoining ribs 6, a tie-rod 12 is anchored, whose upper end is threaded to receive a nut 13, and this rod 12 extends up through the concrete cap-plate 1a, which is mounted on the wall and also through the timber 15 carried by said cap-plate which are held securely anchored together by the nut 13. Anchor rods 16, 16 are provided, whose lower ends are anchored between the respective lugs 10, 10, 11, 11 and their adjoining ribs 6 and the upper ends of these anchor rods are embedded to the cap 141 to hold it securely in place. in the form shown in Figs. 3, 1 and 5, the base plate 1 having the dovetailed groove 2 is employed as in the case in the form shown in the other figures. The wall slabs 17 and 18 are set into this groove as hereinbcfore described, and secured therein by means of the keys 5, as explained. The wall slabs 17 and 18 have the marginal inwardly extending ribs 19, 19 and 20, 20. The joints of the respective slabs are broken, that is, are alternately arranged with respect to the joints of the opposing slabs and the said ribs 19, and also the ribs 20 of the adjacent edges of the slabs it together in pairs as illustrated in Fig. 3. The upper ends of the ribs 19, 19 and of the ribs 20, 20 are set back a distance from the margins of their respective slabs, thus spacing said upper ends apart, said spaced ends 21, 21, and 22 22 converging, forming a dovetailed socket. A cap plate 23 formed of concrete is mounted on the upper ends of said wall slabs and its underside is provided with dovetailed projections 24 which fit into the respective sockets between the converging ends 21, 21 and 22, 22 respectively, and anchor said cap plate against lengthwise or lateral movement. The timber 15 is an chored in place by means of the tie-rods 25, whose lower ends are secured between the upper ends of the ribs and the projec ions 24;, and which project up through said cap plate and timber and whose upper ends r ceive the nuts 26. Anchor rods are also provided in this form as in the form shown in Figs. 1 and 2. Sections 7 of the free edges of the ribs are cut away to provide spaces for the circulation of air, and the cap plates 1 1 and 23 are provided with the circulating air ports 27.

What I claim is 1. A wall construction, including opposing side slabs spaced apart, the edges of said slabs being formed with ribs which extend toward the opposing slabs at approximately right angles thereto, the ribs of the adjacent edges of adjoining slabs fitting together, a cap plate titted onto the upper edge of the wall, and means for anchoring the same in position thereon, said cap plate having air circulating openings therethrough which communicate with the space between said opposing side slabs.

2. A wall construction including opposing side slabs spaced apart, the edges of said slabs being formed with ribs which extend toward the opposing slabs at approximately right angles thereto, the ribs of the adjacent edges 0:15 adjoining slabs -i ting together, said ribs having cut away portions to form air passage, a cap plate fitting onto the upper edge of the wall, and means for anchoring the same in position thereon, said cap plate having air circulating openings therethrough which communicate with the space between said opposing side slabs, whereby continuous horizontal and vertical circulation of air is obtained.

In testimony whereof 1 have signed my name to this specification in the presence of two subscribing witnesses.

NEEDHAM.
