Application December 9, 1948, Serial No. 64,395

1 Claim. (Cl. 72-48) This invention relates to insulated concrete walls for building construction, and in particular a concrete wall having a continuous intermediate section of insulating material formed with units having overlapping flanges at the edges and tied into reinforcing elements of the wall with special studs having hooks at the ends and encased in resilient sleeves to prevent shearing.

The purpose of this invention is to provide an improved method of insulating concrete walls to prevent heat and cold being transmitted or conducted therethrough and which also isolates sound and other vibrations.

Various attempts have been made to insulate concrete walls by chemically treating the concrete or painting or coating the inner and outer surfaces but the continuous mass of concrete provides a positive conductor wherein heat is transmitted through the thickness of the wall. With this thought in mind, the invention contemplates separating the wall into two sections or panels and filling the intermediate area or void with units of insulating material wherein conduction from either side is intercepted and vibrations are isolated.

The object of this invention is, therefore, to provide means for building a continuous insulating panel in a concrete wall wherein the load bearing characteristics of the wall are maintained and in which the entire area of the wall is insulated.

Another object of the invention is to provide means for incorporating insulating material in a concrete wall in which means is provided for preventing sagging of the insulating material.

Another object of the invention is to provide means for incorporating a continuous insulating panel in a concrete wall in which the panel is located by reinforcing elements of the wall.

A further object of the invention is to provide an improved method of constructing an insulated concrete wall in which the wall is of comparatively simple and economical construction.

With these and other objects and advantages in view, the invention consists of the new and useful combination, construction, and arrangement of parts as hereinafter more fully described, set forth in the claim appended hereto and disclosed in the accompanying drawings forming part hereof, wherein:

Figure 1 is a view illustrating the method of incorporating a continuous insulating intermediate slab or panel in a concrete wall with parts of the form of the wall broken away and showing the insulating units of the intermediate panel tied to the reinforcing steel of the wall;

Figure 2 is a side elevational view of a plurality of the insulating units showing tie rods around the units, overlapping flanges at the edges, and parts of reinforcing steel of a wall in which the insulating units may be incorporated;

Figure 3 is a view illustrating one of the insulating units with the overlapping flanges at the edges and showing the reinforcing tie rods around the units;


Figure 3-A is a vertical cross-section through one of the insulating units taken on line 3a3a of Figure 6;

Figure 4 is a cross-section through the lower edge of one of the insulating units taken on line 44 of Figure 6;

Figure 5 is a cross-section similar to that shown in Figure 4 on an enlarged scale and showing one insulating unit mounted upon another with the upper and lower parts of the units broken away; taken on line 5-5 of Figure 2;

Figure 6 is a longitudinal section through the lower part of one of the units taken on line 66 of Figure 3A with the upper parts of the unit broken away;

Figure 7 is a detail showing a side elevation of parts of two of the units as shown in Figure 5, with parts broken away and illustrating a method of connecting the tie rods of the units.

Referring now to the drawings, wherein like reference characters denote corresponding parts, the improved insulated concrete wall of this invention includes a continuous intermediate panel or section of insulating material formed with units 10 which are supported laterally by studs 11 from reinforcing elements 12 and 13 of concrete wall sections 14 and 15 with the units 10 forming a continuous intermediate panel 16.

The units or pads 10 are formed with side panels 17 and 18, upper panels 19, lower panels 20 and end panels 21 and 22. These panels are formed of any suitable stiif material and preferably impervious to moisture and the interior of the units is filled with layers of rock wool or other suitable insulating material, as indicated by the numeral 23 and the units are sealed. These units are provided, at one end, with extending flanges 24 and 25, and at the lower side with extending flanges 26 and 27, as shown in Figure 3. The lower panels 20 of the units are provided with recesses 28, as shown in Figure 6, and the flanges 26 and 27 are provided with slots 29 so that the supporting studs 11 and tie bolts 30 may be extended through the unit, as illustrated in Figure 2.

The tie bolts 30 of the form extend straight through the units and through walls 31 and 32 of the form with the outer ends of the tie bolts held in walers 33 on the studding 34. The tie bolts are provided with nuts 36 and washers 37, as shown in Figure 1.

The units 10 are supported by vertically disposed U- shaped tie rods 38 and horizontally disposed U-shaped tie rods 39 and the tie rods are tied together or welded at the points 40. These tie rods are positioned on the units with the ends extending over the extending flanges on the bottom and at one end and, as illustrated in Figure 7, the extending ends of the tie rod of one unit are inserted under corresponding tie rods of a unit upon which the former unit is positioned. The extending ends of the tie rods at the end of the unit are also inserted under the corresponding tie rods of the adjoining units, as shown in Figure 2.

As the units 10 are assembled the studs 11 are positioned in the recesses 28 and the slots 29 of the extending flanges 26 and 27, and the horizontally positioned hooks 41 on the ends of the studs are hooked around the vertically positioned reinforcing rods 12 and 13 with the vertically positioned hooks hooked over the horizontally disposed reinforcing rods 43 and 44.

With the parts arranged in this manner, the forms of a wall may be set up as illustrated in Figure 1, the reinforcing steel placed in position and the insulating units set up as illustrated in Figure l, the reinforcing steel placed in position and the insulating units set up and held in relation to the steel by the flanges of the studs with hooks on the ends held on the steel and after the parts are secured in position, the concrete is poured to form the wall sections 14 and 15. By this means, a continuously insulated concrete wall is provided and the two wall sections are permanently secured together and held in spaced relation by the studs passing through the insulating panels.

It will be understood that modifications may be made in the design and arrangement of the parts Without departing from the spirit of the invention,

What is claimed is:

A building unit comprising a closed housing including a pair of spaced parallel side panels, upper and lower panels and a pair of spaced parallel end panels, said panels being impervious to moisture, insulating material filling the interior of said housing, an L-shaped flange arranged contiguous to each of said side panels, each of said flanges having lower portions extending beyond the bottom edge and end of said housing, the bottom of said housing being provided with a plurality of spaced arcuate recesses, the lower portion of said flanges having arcuate recesses registering with the recesses in said housing, a first set of vertically disposed spaced parallel U-shaped tie rods embracing said housing, and a second set of vertically disposed U-shaped spaced parallel tie rods arranged at right angles with respect to said first set of tie rods, the ends of said tie rods extending beyond the bottom and ends of 4 said flange for engagement with tie rods of a contiguous unit.
