- the ties support the weight of the concrete, the embedded portions of the ties are steel or other metal alloy, which are very good heat conductors. Consequently, the portion of the ties that reside in the insulation layer needs to be poor conductors. This means that the ties cannot be of a single material, which adds complexity and cost to the manufacturing process.

- 1. Field of the Invention
- The present invention relates to building construction, more particularly, to pre-cast, insulated, concrete panels.
- 2. Description of the Related Art
- Concrete sandwich wall panels are well known in the building construction art. They typically consist of an insulation layer sandwiched between two concrete layers with ties extending through the insulation layer and into the concrete layers to secure the three layers together. In one method of manufacturing, the first concrete layer is poured in a horizontal form and the insulation is placed on the concrete. Before the concrete sets, the ties are pushed through pre-drilled holes in the insulation and into the concrete. The ties have surface irregularities so that, after the concrete flows around the ties and cures, a secure attachment is provided between the concrete and ties. Finally, the second concrete layer is poured on the insulation. The concrete flows around the surface irregularities of the ties to secure the layers together after the concrete cures.
- The above-described method has a number of shortcomings. First, it is very labor intensive because a large number of ties must be individually installed before the bottom concrete layer cures. Second, the purpose of the insulation is to minimize thermal transfer between the concrete layers. In order to minimize thermal transfer, the ties need to be poor heat conductors. However, because the ties support the weight of the concrete, the embedded portions of the ties are steel or other metal alloy, which are very good heat conductors. Consequently, the portion of the ties that reside in the insulation layer needs to be poor conductors. This means that the ties cannot be of a single material, which adds complexity and cost to the manufacturing process. Third, the insulation is composed of extruded polystyrene (XPS), which can only be extruded with a rectangular, board-like cross section, profiled cross sections are not possible. Although XPS is a very good insulator, it does not “breath”, that is, its vapor impermeability is too high, and water vapor can be trapped within the building.
- An object of the present invention is to provide an insulation sheet for insulated concrete panel assemblies that minimizes construction labor.
- Another object is to provide an insulation sheet for insulated concrete panel assemblies that is vapor permeable.
- A further object is to provide an insulation sheet for insulated concrete panel assemblies that can be manufactured at or close to the job site.
- The present invention is an insulation sheet for concrete sandwich wall panels and comprises a sheet base composed substantially of expanded cellular foam and having opposed base surfaces, and a plurality of protrusions integral with the sheet base and extending from each of the base surfaces from a footprint at the base surface to a distal surface away from said base surface, each of the protrusions having a cross-sectional shape such that a width of the distal surface is greater than a width of the footprint.
- A concrete panel employing the insulation sheet of the present invention is made by pouring a first concrete layer into a horizontal form, pushing the insulation sheet into the concrete layer before the concrete sets, and then pouring the second concrete layer onto the insulation sheet.
- The insulation sheet of the present invention is composed of an expanded cellular foam (ECF), which can be molded with surface features and is generally vapor permeable. The insulation sheet has a base and protrusions extending from both base surfaces. The protrusions are generally mushroom-shaped so that the concrete flows around and surrounds the protrusions so as to be anchored in the concrete after it sets. The protrusions can be any shape, such as circular and ring-shaped, although any shape or combinations thereof may be employed.
- Narrow ducts extend through the insulation sheet to allow air between the first concrete layer and the insulation sheet to escape while pushing the sheet into the concrete and to facilitate vapor permeability of the panel.
- So that stacked insulation sheets can slide easily on one another, the surface area of the smallest protrusions is greater than any area of the same shape between protrusions. This means that the protrusions of adjacent stacked sheets will slide on each other rather than falling in between the protrusions. Optionally, in order to facilitate sheets sliding on each other and pushing the sheet into the first concrete layer, the surface of the protrusions are rounded.
- Other objects of the present invention will become apparent in light of the following drawings and detailed description of the invention.
- For a fuller understanding of the nature and object of the present invention, reference is made to the accompanying drawings, wherein:
-
FIG. 1 is a prospective view of a concrete sandwich of the present invention; -
FIG. 2 is a perspective view of a section of the insulation panel of the present invention; -
FIG. 3 is a top view of a section of the panel ofFIG. 2 ; -
FIG. 4 is a cross-sectional view of the panel ofFIG. 3 along the line 4-4; -
FIG. 5 is a cross-sectional view of the concrete sandwich ofFIG. 1 ; and -
FIG. 6 is an enlarged view of a portion of a protrusion. - The present invention is an insulation sheet for use in concrete sandwich wall panels and a concrete sandwich wall panel assembly that employs the insulation sheet.
- A concrete
sandwich wall panel 10 of the present invention is shown inFIG. 1 . The basic method of making thepanel 10 is similar to that of the prior art. Thefirst concrete layer 14 is poured to the desired thickness in a horizontal form. Thislayer 14 is typically a structural component, that is, it bears the weight of other components. The parameters of thefirst layer 14 are dependent upon the use to which thepanel 10 is being put and the strength needed. As a structural component, the thickness of thefirst layer 14 will typically be in the range of six to twelve inches. Thelayer 14 may also include re-enforcement bars as needed according to architectural specifications. - Before the concrete set, the
insulation sheet 12 is pushed into theconcrete layer 14, as explained below. Then thesecond concrete layer 16 is poured onto theinsulation panel 12 in the desired thickness. Thesecond layer 16 is typically of a lighter weight aggregate about one to six inches thick, again depending upon the use to which thepanel 10 is put. Re-enforcement bars and/or wire mesh may be included according to architectural specifications. Theconcrete layers concrete layers panel 10 is put. - The
insulation sheet 12 of the present invention is composed of expanded cellular foam (ECF), rather than the extruded polystyrene (XPS) of the prior art. Examples of ECFs are expanded polystyrene (EPS), expanded polypropylene (EPP), expanded polyethylene (EPE), and expanded copolymers such as polystyrene/polyphenylene oxide and modified polyphenylene oxide and polyphenylene ether. The density of the ECF will vary depending upon the application and will typically be in the range of from one to twelve pounds per cubic foot. - ECF is not restricted to a flat shape, as is XPS. ECF can be molded to include surface features. ECF has some vapor permeability so that water vapor is not trapped within the building. In other words, a
panel 10 made with theinsulation sheet 12 of the present invention “breathes”. Additionally, a “shape-molding” installation is more easily available to a concrete pre-caster, either by in-house investment and in-house production, or by tapping into one of hundreds of local ECF converters that already have ECF manufacturing know-how and an existing ECF infrastructure. Long-term savings would be in either greatly reduced or eliminated costs associated with transporting XPS sheets from one of the relatively few number of suppliers' plants around the country. - The
insulation sheet 12 of the present invention has asheet base 18 and a plurality ofprotrusions sheet base 18. The thickness of thebase sheet 18 will depend upon how much insulation is desired and can typically be in the range of from one to twelve inches. - As shown in the cross-section of
FIG. 4 , the width of thedistal surface 26 of theprotrusion 20 is generally larger than the width of theprotrusion footprint 28, the area of theprotrusion 20 at thebase surface 22. In other words, the protrusion cross-section is generally mushroom-shaped. The idea is that, when thesheet 12 is pushed into unset concrete, the concrete flows around and surrounds theprotrusions 20, as at 30 inFIG. 5 . When the concrete sets, theprotrusions 20 are anchored in the concrete. With protrusions extending from both base surfaces 22, 24, theconcrete layers insulation sheet 12, thereby creating an insulated concrete sandwich. The height of theprotrusion 20 and theangle 42 of theprotrusion side wall 40 are dependent on the density of the ECF used for theinsulation sheet 12 and to the weight and density of theconcrete layers protrusions 20 can typically range in height from ½ inch to two inches and theside wall angle 42 can typically range from one to ten degrees. - Because of the integral protrusions, there is no need to manually insert individual ties, like the panels of the prior art. Consequently, manufacturing labor cost is greatly reduced.
-
FIGS. 2-5 show two different shapes for the protrusions 20: aring protrusion 20 a and acircular protrusion 20 b. These are merely illustrative shapes and the present invention contemplates that any protrusion shape or combinations of protrusion shapes that have the characteristics described herein may be employed. For example, all the protrusions can be circular or the protrusions can be other shapes, such as squares and rectangles. The size of the protrusions can vary greatly depending upon the application. The ring protrusions 20 a can be, for example, three to ten inches in diameter and thecircular protrusions 20 b can be, for example, one to five inches in diameter. -
Narrow ducts 32 extend through theinsulation sheet 12 at various locations, providing two functions. First, they allow air between the firstconcrete layer 14 and theinsulation sheet 12 to escape while pushing thesheet 12 into the concrete, thereby reducing the possibility of air bubble formation. Second, theducts 32 facilitate vapor permeability of the final product. Theducts 32 are small enough so that concrete will not fill them. Because a thinner concrete mix would more easily fill larger ducts, the diameter of theducts 32 is dependent on the viscosity and aggregate mix of the concrete. - Typically, the
insulation sheets 12 are stacked for delivery to where the panels are manufactured. It is desirable that, as aninsulation sheet 12 is needed for apanel 10, thesheet 12 be easily slid from the top of thestacked sheets 12. Because the XPS insulation sheets of the prior art are flat, they can be slid off quite easily. The insulation sheet of the present invention solves this issue by usingprotrusions 20 with a smallest distal surface area that is greater than any area of the same shape betweendistal surfaces 26. For example, inFIG. 3 , thesmallest protrusion 20 is circular and thedistal surface diameter 34 is greater than the largest circular space 36 betweendistal surfaces 26. This means that thedistal surfaces 26 ofprotrusions 20 ofadjacent sheets 12 will slide on each other rather than falling in between theprotrusions 20. - If the
distal surfaces 26 are flat, slight irregularities in theprotrusions 20 may cause theprotrusions 20 ofadjacent sheets 12 to catch each other when trying to slide onesheet 12 off a stack. To solve this issue, thedistal surface 26 of theprotrusions 20 are optionally rounded, as inFIG. 4 . In the case of thering protrusions 20 a, theprotrusion 20 a has a raised ridge in the center of thedistal surface 26 that is rounded to the two edges 36. In the case of thecircular protrusions 20 b, theprotrusion 20 b is domed. The roundeddistal surface 26 facilitates sliding thesheets 12 along each other because theedges 38 of theprotrusions 20 will not catch on each other. - Another advantage of the rounded
distal surface 26 is that it is easier to push into the firstconcrete layer 14. The present invention contemplates other shapes for the distal surface, for example, pointed, that facilitate pushing theinsulation sheet 12 into theconcrete layer 14. - Thus it has been shown and described an insulation sheet and a concrete sandwich assembly constructed therewith that satisfies the objects set forth above.
- Since certain changes may be made in the present disclosure without departing from the scope of the present invention, it is intended that all matter described in the foregoing specification and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense.
