Abstract
An insulated concrete wall system is disclosed in which the insulation is provided at the time the concrete wall is poured.
Description
- The present invention relates to poured concrete walls and, more particularly, to poured concrete walls including layers of thermal insulation in which the insulation layers are secured to the concrete wall at the time of pouring the concrete.
- Concrete walls are commonly formed by pouring concrete between inner and outer forms and, after hardening, insulation materials may be added to the concrete walls. In order to do so, frame members may be applied to the concrete wall, such as by using pneumatic guns and concrete nails, and then the insulating material may be secured to the frame members. Alternatively, the insulation may be secured to the concrete wall by concrete nails. Such multi-step assembly procedures are both time consuming and costly. Thus, there has long been a need for a system and a method whereby poured concrete walls may be formed and insulated at the same time in one step, and particularly when both the inner and outer surfaces of the wall are to be insulated.
- The present invention provides an apparatus and method for securing insulation layers in place while the concrete is poured between conventional forms, and for continuing to secure the insulation layers to the poured concrete wall after the forms have been removed.

FIG. 14 is a top cross-sectional view taken along view line 14-14. - Referring first to
FIG. 1 ,numeral 10 designates a concrete wall which has been poured between first and secondconventional forms Forms ties 16 as in conventional practice. However, as shown most clearly inFIG. 3 , each ofties 16 includes anon-conventional slot 17 for a purpose hereinafter described.Numeral 18 represents a conventional footing for supporting the wall, andnumeral 20 represents a plurality of conventional reinforcing bars (“rebar”) which extend horizontally through the poured concrete to add strength to the wall. - The structure described thus far is typical of the manner of forming poured concrete walls. After the concrete hardens, forms 12 and 14 are removed and the concrete wall is complete. If insulation is to be added, frame members (not shown) must be secured to the wall, or sheets or rolls of insulation must be secured by pneumatic nailing guns. As previously stated, this double-step procedure is both time consuming and costly.
- In the present invention, layers or panels of
insulation 22 are secured in place before the concrete is poured betweenforms wedges 23 and anchors orconnectors 24. Clips orwedges 23, hereinafter wedges, are shown in detail inFIGS. 2 and 4 . Each wedge comprises a molded piece of plastic, such as polypropylene, which is in the form of a double-ended V-shape with anopen hole 26 in the central region. As such, the wedges are flexible and resilient so that they may be squeezed together in the center portion and inserted intoslots 17 ofties 16. Upon insertion, the center portions of the wedges expand such that grooves 28 lock inties 16 and the wedges extend horizontally. As shown most clearly inFIG. 2 , approximately one-half of each wedge becomes embedded in the insulation panel, and the other half becomes embedded in the poured concrete. As a result, the insulation panels become locked to fixedties 16 so that the lightweight panels cannot “float” upwardly when the concrete is poured. - In addition to
ties 16 andwedges 23, the present invention provides anchors orconnectors 24 as shown inFIGS. 1 and 5 -7. Preferably,connector elements 24 are in the form of aweb portion 32 havingopenings 34 so that the poured concrete passes through and fills the openings as-shown inFIG. 1 . Thus, as the concrete hardens,connectors 24 become bound and locked in the concrete. - As further shown most clearly in
FIGS. 1 and 5 -7, eachconnector 24 includes an enlargedhead portion 36 which extends laterally and vertically at a right angle relative to the web portion. Thus, when the web portion of each connector passes through aslot 38 in the insulation panel as shown inFIGS. 1 and 8 , the panel is retained byhead portion 36 while the web portion is retained in and by the concrete. In the preferred embodiment, it will be understood that the area of theinsulation surrounding slot 38 may be recessed or counter-sunk such that the exposed surface of the connector head is flush with the surface of the insulation. However, the thickness of the head portion is only in the order of ¼ inch or less such that counter-sinking is not necessary. - Also in the preferred embodiment, stiffening side bars or
ribs 37 may be added as most clearly shown inFIGS. 5 and 7 , and the stiffening ribs may be provided withbarbs 39 for engaging ininsulation layer 22. Also, the upper and lower portions ofconnectors 24 may be provided withbarbs 41 which further engage and hold the insulation panel in place. In addition, in order to accommodate walls of either 6 or 8 inches in thickness, the horizontal length ofconnectors 24 may be manufactured of a uniform 8 inch length, and withgrooves 42 as shown inFIG. 5 near the tip of the connector such that the tip may be easily broken off for 6 inch walls. - In the foregoing description,
connectors 24 may be held in place during the concrete pouring by virtue of a tight frictional fit between theweb portion 32 andslot 38 of the insulation panel and the frictional engagement ofbarbs hook portions 40 as shown inFIGS. 1 and 5 . These hook portions may be engaged by rebar 20 so as to positively lockconnectors 24 in place before, during and after the concrete is poured. -
Connectors 24 may be composed of any rigid material, but they are preferably composed of molded plastic such as for example, polypropylene or polyethylene. Such materials may be easily molded, are of low thermal conductivity and are low cost. Most importantly, they provide an excellent medium for receiving nails, screws, staples or other means throughheads 36 for securing the later installation of additive wall materials such as plaster board, paneling or other finishing layers. -
Insulation layer 22 may be composed of any commercially available material of low thermal conductivity, but is preferably composed of rigid panels of expanded or extruded polystyrene. In addition to the thermal insulation value of such panels, their inherent properties provide a vapor barrier and their thermal properties are not deteriorated by moisture. - The above-identified structure and method of forming the insulated wall has proven to be very effective and efficient in insulating a concrete wall. At the same time, it has been discovered that newly developed structure and methods greatly expedite the entire process and substantially reduce the cost. For example, the previous method of construction included forming 6 to 9
slots 38 in each single panel of insulation as shown inFIG. 8 . These slots were of uniform width, and they required “plunge-cutting” each slot with a mechanical cutter such as a chain cutter similar to the well-known chain saw. With each plunge into the single insulation panel an upper vertical portion of the slot was cut, and then the cutter moved downwardly to complete the vertical length of the slot, after which it was withdrawn. Then the cutter, or a second similar plunge-type cutter, was inserted into the single layer of insulation to cut the laterally extendingslot portions 44 in order to receive laterally extendingbarbs 39 of each web. While multiple slots could be cut simultaneously by using a support structure for mounting an array of cutters, the entire cutting process was slow and subject to frequent mechanical breakdown of the cutters and/or the cutter support structure. - It has now been discovered that a large block of insulation, such as
block 46 inFIG. 9 , may havevertical slots 38 cut in a single step by cutting through theentire block 46 with a hot wire cutter moving only vertically. The cutter need not move horizontally because it has been found thatribs 37, shown inFIG. 7 , may be eliminated with the barbs extending latterally from the sides of the webs as shown inFIGS. 10 and 12 . It has also been found that the preferred method of cutting is to enter the block from one side, cut out a key 44 for added strength, and then cut thevertical slot 38. Thereafter, block 46 may be sliced intoindividual layers 48 by a hot wire or other type cutter so as to manufacture as many as 12 layers of insulation in only two steps. This method both substantially increases the efficiency and lowers the production cost of each finished insulation panel. - In addition, it has also been discovered that the exterior surface of the wall may also be provided with a layer of insulation in combination with, or apart from, the description of the inner layer of insulation as just described. Referring first to
FIGS. 10 and 11 it will be understood thatinsulation panel 22 a has been prepared withslots 38, preferably by the new method, and a plurality ofwebs 24 have been inserted into the slots. However, it will be noted that thehead portions 36 ofwebs 24 are left protruding outwardly from the surface of the insulation panel. - At this point in the assembly, a
channel member 50, as shown inFIGS. 10 and 11 , is slid down over the heads of the webs as shown by an arrow A inFIG. 10 . Thereafter the channel and the webs are driven into the surface ofinsulation panel 22 as shown inFIG. 12 . In this regard it will be understood that the vertical edges of the channel are sharp enough to cut into the insulation panel such as to be flush with the surface of the panel. The panel is then slid horizontally between two conventional wall forms 12, 14 as shown inFIG. 1 such that the tapered ends of the webs extend into the space between the wall forms into which space the concrete is later poured. The channels lock over the heads of the webs and provide strips of metal or plastic to receive connectors such as nails, staples, etc. for securing whichever form of siding is desired on the outer wall of the building, or for securing panels or the like on the inside of the wall when theFIG. 10-14 embodiment is used in the inner surface of the concrete wall. - After each panel is slid into place between the wall forms, conventional ties 16 (shown in
FIG. 1 ) are connected to the wall forms at the edge of the panel. The wedges 23 (shown inFIG. 1 ) are inserted into the installed panel, and extend into the edge of the next panel when the latter is slid into place. - As shown in
FIGS. 13-14 outer insulation panels 22 a may be used in combination with theinner insulation panels 22, or it will be readily understood thatpanels 22 a may be used to insulate only the outer wall of the concrete wall. - When both the inner and outer walls are to be insulated, each of
panels only panel 22 a, so as to form the double insulated wall as shown inFIG. 13 , the webs being next to each other and overlapping as shown inFIG. 14 . It will also be understood that a plurality ofouter panels 22 a may be stacked vertically so as to insulate more than one story of a building, and they may be used below grade with a waterproofing coating or membrane between the earth and the insulation panel. With the double sided insulation, R values as high as 50 may be obtained, and when only the outer surface of the wall is to be insulated, it is only necessary to eliminatepanel 22 and use shorter ties. - With the simple elements and method of construction as described above, one or both sides of the concrete wall may be insulated without a second step of securing insulation after the concrete is poured and hardened. Thus, the total structure is both low in cost and can be installed much more rapidly and efficiently than previously known apparatus or methods in the concrete wall industry.
- From the foregoing description of two preferred embodiments it will be apparent that numerous variations in the details will be readily apparent to those skilled in the art. Accordingly, it will be understood that the foregoing description is purely illustrative of the principles of the invention, and that the invention is not intended to be limited other than as expressly set forth in the claims interpreted under the doctrine of equivalents.
