C. B. JONES TIE BAR FOR INSULATED CONCRETE WALLS Filed D06. 9, 1948 INVENTR.
July 21, 1953 Patented July 21, 1953 UNITED STAT Es PAT TIE ma Fon INSULATED CONCRETE WALLS vCable B. Jones, Black Hawk, S. Dak. Application December 9, 1.948, Serial No. 64,396
1 claim. (c1. 72-1o`sI 1 This invention relates to tiek rods for holding reinforcing steel or" concrete walls andinsulating panels Vor pads in the walls in spaced relation,
and in particular a tie rod having hooks on both n of aconcrete wall through reinforcing steel in v the sections and for holding a continuous panel of insulating material in position between the wall sections as the wall is poured. y
The tie bar of this invention is particularly adapted for retaining the insulating pad or intermediate section of my co-pending application` crete wall a continuous slab or panel is provided so lthat permanent tie rods therein are not required; however, where a concrete wall is divided by a continuous intermediate insulating panel two spaced wall sections are provided and it is necessary to permanently tie these sections together through the insulating panels. With this thoughin mind, this invention contemplates a tie rod having hooks on the ends that may be positioned through the insulating panel with the ends extended into the intermediate part of the spaced wall sections wherein the hooks at the ends are hooked over reinforcing elements in the said spaced Wall sections. v
The object of this invention is, therefore, to provide positive tying elements for securing spaced wall sections together through reinforcing elements in the sections and with the rods extended through and holding insulating units between the sections in spaced relation to the wall sections.
Another object of the invention is to provide means on permanently positioned tie rods for spaced concrete wall sections in which freedom of movement of the rods in relation to the sections is provided to prevent shearing the rods by uneven contraction or settling of the concrete.
Another object of the invention is to provide a tie rod for securing spaced wall sections to- 2 1 f gether through reinforcing steel therein wherein the tying elements are installed without bolts or nuts. 'Y
A further object of the invention is to provide self-contained'tie rods for securing spaced concrete wall sections in spaced relation with an insulating panel between the sections which are comparatively simple and inexpensive to rmanufacture.
With these and other objectsl and'advant'ag'es in View, the inventioniconsists of the new: and useful combination, construction and arrange'- ment of parts, as hereinafter more fully described, set forth in the claim appended hereto,
and disclosed Ain the accompanying Vdrawing forming part hereof, wherein:
Figure 1 is a View showing a vertical crosssection through a wall illustrating the improved tie rod in use with the tie rod extended through an intermediate insulating panel and with the end hooked over reinforcing steel elements of spaced concrete wall sections; t
Figure 2 is a plan view of the tie rod shown in Figure l with the form omitted;
Figure 3 isy a perspective View showing one of the tie rods with flanged resilient sleeves thereon and with parts of reinforcing steel shown in dotted lines; v
Figure 4 is a detail showing one end of one of rthe tie rods with a tapered resilient sleeve shown thereon in section; p y
Figure 5 is a detail illustrating a m'odicatio-n wherein the ends of the'tie' rods are provided with a plurality of hook-like elements.
Referring now to the drawingsr wherein like reference characters denote corresponding parts, the reinforcing steel tie rod of this invention includes a rod I0 having hooks II and I2 at one end Iand I3 land I4 at the other.
The rods are illustrated as being round, however, it Will be understood that steel of any vother shape in cross-section may be used.
Each end of the tie rod is p-rovided with a" sleeve I5 that may be formed of rubber or other material Vfor forming a yielding area in the concrete around the ends of the rod and the outer surface of the sleeve may be tapered, as shown. The rods are provided with spaced flanges I6 which are integral with the rods and these are positioned against the sides of the intermediate insulating panel of the wall to position the insulation between the forms and hold the insulation in spaced relation to the forms as the concrete is poured.
In the design shown in Figure 5, tie rods I1 ENTv .oFFIcEf are provided with hook-like elements I8 and I9 and also similarly shaped elements 20 and 2| which are spaced from the hook-like elements I8 and I9, and this rod is also provided with resilient sleeves I5 and flanges I 6. The opposite end of the rod I'I may also be provided with similar elements. The sleeves serve to allow freedom of motion of the tie bar.
In use, the tie rods I are extended through an intermediate insulating panel 22, which is formed with sides 23 and 24 and provided with overhanging flanges 25 and 28 that extend over a similar section of the panel, as shown in Figure 1, and with the tie rods positioned in the insulating panel in this manner, with the circular flanges I6 against the sides of the insulating material the panel is held in position. The hooks I I and I3 at the ends of the tie rods extend around vertical reinforcing rods 2I and 28 and the hooks I2 and Il extend over horizontally disposed reinforcing rods 29 and 30. In the design shown, the reinforcing rods are positioned substantially midway between the outer surfaces of the insulating panel and the sides 3| and 32 of the forms of the Wall. With the parts positioned in this manner, the form is ready for the concrete and as the concrete is poured, the hook-like end of the rods with the resilient sleeves I thereon are embedded in the concrete and should the concrete of one side wall set or contract more than the other, the resilient sleeves permit the ends of the tie rods to move upwardly or downwardly or laterally to compensate for strains and stresses resulting from uneven expansion and contraction of the outer and inner Wall sections that may cause the tie rods to break or the concrete to be crushed or broken.
It will be understood that modifications may be made in the design and arrangement of the elements without departing from the spirit of the invention.
What is claimed is:
A tying device for reinforced concrete construction comprising a rod having a pair of hooks on each end thereof, and spaced annular spacing flanges intermediate of and spaced from the ends, said flanges being integral with said rod, the hooks of each pair being positioned in substantially perpendicular relationship to each other, and tapering yieldable sleeves positioned on the ends of the rod between the flanges and hooks, the thin edges of said sleeves being positioned adjacent the hooks and the thick edges positioned against the flanges.
