Definitions
- the insulated wall structure consists of a plurality of metal liner sheets each provided with a foamed plastic core.
- the metal liner sheets are secured to the building structural framework by first fastening means penetrating the foamed plastic cores and the metal liner sheets.
- a plurality of corrugated facing sheets are erected in side-by-side relation and abut the foamed plastic cores.
- the corrugated facing sheets are secured to the structural framework by second fastening means penetrating the corrugated facing sheets, the foamed plastic cores and the metal liner sheets.
- the foamed plastic cores provide firm supporting surfaces for the corrugated facing sheets, maintain the corrugated facing sheets separated from the metal liner sheets and serve as thermal insulation.
- This invention relates to an insulated wall structure which is field erected to a building structural framework, and more particularly to an insulated wall structure of the type consisting of a plurality of metal liner sheets each provided with a foamed plastic core self-adhered to the metal liner sheet, and a plurality of corrugated facing sheets.
- insulated wall structures have been assembled by (a) erecting a plurality of metal liner sheets in side-by-side relation to form an inner metal sheath, (b) applying batts of insulating material, such as glass wool and the like, to the metal liner sheets, (c) securing subgirt members to the metal liner sheets outboard of the insulating material, and (d) securing outer facing sheets to the subgirt members to form an outer metal sheath.
- batts of insulating material such as glass wool and the like
- insulated wall structures include the relatively complicated erection procedures and high labor costs required to assemble the numerous wall components; the through conduction of heat due to extensive areas of metal-to-metal contact between the inner and outer sheets; and the relatively high total cost of the numerous wall components.
- Insulated wall structures assembled from modular panel units are also known in the prior art. See for example, US. Patents 1,697,189; 2,912,725; 3,070,196; 3,094,198; 3,113,401; 3,310,926.
- Such modular panel units include a metal liner sheet secured to a metal facing sheet and conventional insulating materials such as glass wool, mineral fibers and the like, filling the space between the sheets.
- Such modular panel units are intended to serve as building structural members and, as such, are erected in sideby-side interlocked relation to a building structural framework.
- the major disadvantage of such modular panel units is the severe through conduction of heat encountered at the joints between adjacent modular panel units.
- the prior art provides still another type of modular panel unit whose development resulted from the relatively recent availablity of insulating materials, such as foamed polyurethane, foamed polystyrene and the like.
- insulating materials such as foamed polyurethane, foamed polystyrene and the like.
- Such prior art panel units are best termed modular foamed plastic core panel units and can be erected in side-by-side relation to form an insulated wall structure. See for eample, US. Patents 3,062,337; 3,113,401; 3,310,926; 3,290,845. See also, Canada Patent 734,901 and Belgium Patent 696,876.
- Such prior art modular foamed plastic core panel units comprise a pair of facer sheets having a foamed plastic core disposed therebetween.
- the foamed plastic core can be produced by introducing an actively foaining liquid mixture between the facer sheets and thereafter allowing the mixture to expand into contact with and to adhere to the opposed faces of the facer sheets.
- the facer sheets must be restrained to resist the relatively high pressures produced by the expanding actively foaming liquid mixture.
- Apparatus employed to restrain the facer sheets includes cumbersome and complex mold equipment, armored conveyors and the like.
- the major disadvantages of these prior art modular foamed plastic core panel units include the high cost of the materials constituting the foamed plastic core; the high cost of the relatively complex equipment employed toproduce the panel unit; the relatively high cost associated with the operation of the complex equipment; and the relatively slow production rate at which the panels are produced.
- Such prior art modular foamed plastic core panel units are intended to serve as building structural members wherein the foamed plastic core fills the entire space between the facer sheets and acts as a shear connecting core.
- the facer sheets serve as the compression and tension flanges of the panel in beam action.
- the foamed plastic core acts compositely with the facer sheets and transfers shear stresses from one sheet to the other.
- other essential considerations in the production of such prior art modular foamed plastic core panel units include the strength of the bonds between the foamed plastic core and the facer sheets; the humid-aging characteristics of the foamed plastic core; and those physical properties of the foamed plastic core, such as tensile strength, yield strength, compressive strength, shear strength and modulus of elasticity.
- the production of such prior art modular foamed plastic core panel units requires extensive quality control procedures which add considerably to the overall cost of producing the panel units.
- the principal object of this invention is to provide an insulated wall structure which is assembled by sequentially erecting (a) a plurality of metal liner sheets, each liner sheet being provided With a foamed plastic core material, and (b) corrugated facing sheets, each facing sheet abutting the foamed plastic core material.
- Another object of this invention is to provide an insulated wall structure wherein the principal virtues of the use of a foamed plastic core material as thermal insulation are retained but which avoids the major disadvantages heretofore encountered by the prior art in the use of such foamed plastic core materials.
- Another object of this invention is to provide an insulated metal Wall structure which does not require the use of intermediate subgirt members interposed between the metal liner sheets and the metal facing sheets.
- Still another object of this invention is to provide an insulated wall structure incorporating a foamed plastic core material serving as an insulating member and as a spacer member for maintaining the liner sheets separated from the facing sheets.
- the present invention provides an insulated wall structure of the type assembled from a plurality of metal liner sheets each provided with a foamed plastic core; a plurality of corrugated facing sheets abutting the foamed plastic cores; first fastening means securing the metal liner sheets to a building structural framework; and second fastening means securing the corrugated facing sheets to the building structural framework.
- the metal liner sheets are erected in side-byside interlocked relation and are secured to the building structural framework.
- the metal liner sheets provide an inner sheath which completely encloses the building structural framework.
- the facing sheets are erected in side-by-side overlapped relation, in direct engagement with the foamed plastic cores and are secured to the building structural framework.
- the corrugated facing sheets are maintained separated from the metal liner sheets by means of the foamed plastic cores. No intermediate subgirt menibers are used or are necessary in the assembly of the present insulated wall structure.
- the foamed plastic cores are self-adhered to the metal liner sheets and serve as insulating members and as spacer members.
- the self-adherent bond between the metal liner sheet and the foamed plastic core reliably but provisionally joins the metal liner sheet to the foamed plastic core to form an inner panel unit capable of withstanding handling during manufacturing, packaging, shipping and erection.
- This self-adherent bond is disregarded when the structural strength of the wall structure is determined, notwithstanding the fact that it may have substantial strength.
- the structural strength required of the insulated wall structure is developed by the corrugated facing sheets. Nevertheless, the principal virtues of the use of a foamed plastic core material as thermal insulation are retained in the present insulated wall structure.
- the normally textured exposed foamed plastic core surface is modified, for example by calendering, to produce an essentially smooth surface and to reduce the thickness of the foamed plastic core to a desired value. Consequently, when a plurality of the present inner panel units are erected to a building structural framework, the essentially smooth foamed plastic core surfaces will be substantially coplanar and provide firm supporting surfaces for engagement by the subsequently erected corrugated facing sheets.
- the benefits gaincd by producing the present inner panel units in the manner taught by this invention include: the elimination of complex fabrication facilities; the elimination of great volumes of relatively expensive foamed plastic core filling; and avoidance of panel bulging which occurs in prior art modular foamed plastic core panel units.
- the benefits gained by assembling an insulated wall structure in the manner taught by this invention include substantial cost savings in materials, packaging, shipment and erection.
- the present inner panel units metal liner sheet with foamed plastic core
- the corrugated facing sheets may be conveniently and efficiently nested, packaged and shipped to the building site. Erection of the present insulated wall structure components is facilitated by the absence of intermediate subgirt members.

- the preferred pouring technique will produce a foamed plastic core 32 having a generally uniform thickness, indicated at 76 in FIGURE 6, throughout its entire area and a generally smooth but textured foamed plastic core surface 78. It is desirable to modify the textured foamed plastic core surface 78, for example by calendering, to produce the aforesaid essentially smooth foamed plastic core surface 72 and to reduce the normal thickness 76 of the foamed plastic core 32 to the desired thickness 74.
- Apparatus for calendering the textured foamed plastic core surface 78 is schematically illustrated in FIGURES 5 and 6 and includes a conveyor 80 which conveys the inner panel unit 28 beneath a calendering roll 82 driven by suitable drive means indicated at 84.
- the calendering roll 82 is supported by means (not illustrated) which permits the calendering roll 82 to be vertically adjusted at selected distances from the conveyor 80. Pressure is applied to the calendering roll 82 by means schematically illustrated by the arrows 86.

- intermediate subgirt members normally found in similar prior art insulated wall structures, are conspicuously absent from the present insulated wall structure 20. Such intermediate subgirt members are not needed and their omission reduces the materials cost and the erection cost of the present wall structure 20. Since intermediate subgirt members are essential to the assembly of similar prior art insulated wall structures, their omission from the present insulated wall structure 20 constitutes an improvement over similar prior art insulated wall structures. Furthermore, the use of intermediate subgirt members normally is accompanied by extensive areas of metal-t0- metal contact between the metal liner sheets and the metal facer sheets. Such metal-to-metal contact promotes through conduction of heat and results in a greater overall heat transfer coefficient. Consequently, the omission of intermediate subgirt members from the present wall structure 20 lowers its overall heat transfer coeflicient.

BACKGROUND OF THE INVENTION Field of the invention This invention relates to an insulated wall structure which is field erected to a building structural framework, and more particularly to an insulated wall structure of the type consisting of a plurality of metal liner sheets each provided with a foamed plastic core self-adhered to the metal liner sheet, and a plurality of corrugated facing sheets.
Description of the prior art Heretofore, insulated wall structures have been assembled by (a) erecting a plurality of metal liner sheets in side-by-side relation to form an inner metal sheath, (b) applying batts of insulating material, such as glass wool and the like, to the metal liner sheets, (c) securing subgirt members to the metal liner sheets outboard of the insulating material, and (d) securing outer facing sheets to the subgirt members to form an outer metal sheath. See for example US. Patents 2,728,423; 2,744,589; 2,841,253; 2,876,871; 2,910,150; 2,910,151; 2,918,993; 3,054,482; 3,300,934. The major disadvantages of such insulated wall structures include the relatively complicated erection procedures and high labor costs required to assemble the numerous wall components; the through conduction of heat due to extensive areas of metal-to-metal contact between the inner and outer sheets; and the relatively high total cost of the numerous wall components.
Insulated wall structures assembled from modular panel units are also known in the prior art. See for example, US. Patents 1,697,189; 2,912,725; 3,070,196; 3,094,198; 3,113,401; 3,310,926. Such modular panel units include a metal liner sheet secured to a metal facing sheet and conventional insulating materials such as glass wool, mineral fibers and the like, filling the space between the sheets. Such modular panel units are intended to serve as building structural members and, as such, are erected in sideby-side interlocked relation to a building structural framework. The major disadvantage of such modular panel units is the severe through conduction of heat encountered at the joints between adjacent modular panel units.
The prior art provides still another type of modular panel unit whose development resulted from the relatively recent availablity of insulating materials, such as foamed polyurethane, foamed polystyrene and the like. Such prior art panel units are best termed modular foamed plastic core panel units and can be erected in side-by-side relation to form an insulated wall structure. See for eample, US. Patents 3,062,337; 3,113,401; 3,310,926; 3,290,845. See also, Canada Patent 734,901 and Belgium Patent 696,876. Such prior art modular foamed plastic core panel units comprise a pair of facer sheets having a foamed plastic core disposed therebetween. The foamed plastic core can be produced by introducing an actively foaining liquid mixture between the facer sheets and thereafter allowing the mixture to expand into contact with and to adhere to the opposed faces of the facer sheets. The facer sheets must be restrained to resist the relatively high pressures produced by the expanding actively foaming liquid mixture. Apparatus employed to restrain the facer sheets includes cumbersome and complex mold equipment, armored conveyors and the like.
The major disadvantages of these prior art modular foamed plastic core panel units include the high cost of the materials constituting the foamed plastic core; the high cost of the relatively complex equipment employed toproduce the panel unit; the relatively high cost associated with the operation of the complex equipment; and the relatively slow production rate at which the panels are produced.
Such prior art modular foamed plastic core panel units are intended to serve as building structural members wherein the foamed plastic core fills the entire space between the facer sheets and acts as a shear connecting core. The facer sheets serve as the compression and tension flanges of the panel in beam action. The foamed plastic core acts compositely with the facer sheets and transfers shear stresses from one sheet to the other. Hence, other essential considerations in the production of such prior art modular foamed plastic core panel units include the strength of the bonds between the foamed plastic core and the facer sheets; the humid-aging characteristics of the foamed plastic core; and those physical properties of the foamed plastic core, such as tensile strength, yield strength, compressive strength, shear strength and modulus of elasticity. Thus, it will be appreciated that the production of such prior art modular foamed plastic core panel units requires extensive quality control procedures which add considerably to the overall cost of producing the panel units.
SUMMARY OF THE INVENTION The principal object of this invention is to provide an insulated wall structure which is assembled by sequentially erecting (a) a plurality of metal liner sheets, each liner sheet being provided With a foamed plastic core material, and (b) corrugated facing sheets, each facing sheet abutting the foamed plastic core material.
Another object of this invention is to provide an insulated wall structure wherein the principal virtues of the use of a foamed plastic core material as thermal insulation are retained but which avoids the major disadvantages heretofore encountered by the prior art in the use of such foamed plastic core materials.
Another object of this invention is to provide an insulated metal Wall structure which does not require the use of intermediate subgirt members interposed between the metal liner sheets and the metal facing sheets.
Still another object of this invention is to provide an insulated wall structure incorporating a foamed plastic core material serving as an insulating member and as a spacer member for maintaining the liner sheets separated from the facing sheets.
The present invention provides an insulated wall structure of the type assembled from a plurality of metal liner sheets each provided with a foamed plastic core; a plurality of corrugated facing sheets abutting the foamed plastic cores; first fastening means securing the metal liner sheets to a building structural framework; and second fastening means securing the corrugated facing sheets to the building structural framework.
Initially, the metal liner sheets are erected in side-byside interlocked relation and are secured to the building structural framework. The metal liner sheets provide an inner sheath which completely encloses the building structural framework. Thereafter, the facing sheets are erected in side-by-side overlapped relation, in direct engagement with the foamed plastic cores and are secured to the building structural framework. In the present insulated wall structure, the corrugated facing sheets are maintained separated from the metal liner sheets by means of the foamed plastic cores. No intermediate subgirt menibers are used or are necessary in the assembly of the present insulated wall structure.
The foamed plastic cores are self-adhered to the metal liner sheets and serve as insulating members and as spacer members. The self-adherent bond between the metal liner sheet and the foamed plastic core reliably but provisionally joins the metal liner sheet to the foamed plastic core to form an inner panel unit capable of withstanding handling during manufacturing, packaging, shipping and erection. This self-adherent bond is disregarded when the structural strength of the wall structure is determined, notwithstanding the fact that it may have substantial strength. Once the present insulated wall structure is erected, the structural strength required of the insulated wall structure is developed by the corrugated facing sheets. Nevertheless, the principal virtues of the use of a foamed plastic core material as thermal insulation are retained in the present insulated wall structure.
In producing the inner panel units of the present invention, the normally textured exposed foamed plastic core surface is modified, for example by calendering, to produce an essentially smooth surface and to reduce the thickness of the foamed plastic core to a desired value. Consequently, when a plurality of the present inner panel units are erected to a building structural framework, the essentially smooth foamed plastic core surfaces will be substantially coplanar and provide firm supporting surfaces for engagement by the subsequently erected corrugated facing sheets.
The benefits gaincd by producing the present inner panel units in the manner taught by this invention include: the elimination of complex fabrication facilities; the elimination of great volumes of relatively expensive foamed plastic core filling; and avoidance of panel bulging which occurs in prior art modular foamed plastic core panel units.
The benefits gained by assembling an insulated wall structure in the manner taught by this invention include substantial cost savings in materials, packaging, shipment and erection. For example, the present inner panel units (metal liner sheet with foamed plastic core) may be conveniently and efiiciently stacked, packaged and shipped to the building site. Also, the corrugated facing sheets may be conveniently and efficiently nested, packaged and shipped to the building site. Erection of the present insulated wall structure components is facilitated by the absence of intermediate subgirt members.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S) Referring to FIGURES 1 and 2, there is illustrated an insulated wall structure 20 secured to a building structural framework 22 which includes vertical columns 24 (only one shown) and vertically spaced, horizontal girts 26 (only one shown). The insulated wall structure 20 consists of a plurality of inner panel units 28 erected in sideby-side interlocked relation and each consisting of a metal liner sheet 30 provided with a foamed plastic core 32; first fastening means 34 for securing the inner panel units 28 to the building structural framework 22; a plurality of corrugated facing sheets 36 erected in side-by-side overlapped relation in direct engagement with the foamed plastic cores 32; and second fastening means 38 for securing the corrugated facing sheets 36 to the building structural framework 22.
Referring to FIGURE 3, the corrugated facing sheet 36 presents alternating crests 40 and valleys 42 and inclined webs 44 connecting adjacent ones of the crests 40 and the valleys 42. The valleys 42 present facing sheet surfaces 46 which engage the foamed plastic cores 32 (FIGURE 1) when the corrugated facing sheet 36 is erected. The corrugated facing sheet 36 is provided with an overlapped edge portion 48 and an overlapping edge portion 50 along its opposite longitudinal edges. The overall arrangement is such that a plurality of the corrugated facing sheets 36 may be erected in side-by-side overlapped relation as will hereinafter be more fully described. The corrugated facing sheet 36 has a typical profile. Other facing sheets having profiles different from the profile of the facing sheet 36 also can be used in the present insulated wall structure. Furthermore, the corrugated facing sheet 36 may be reversed such that when erected, the crests 40 are engaged directly with the foamed plastic core 32 while the valleys 42 are spaced therefrom.
Referring to FIGURE 4, the metal liner sheet 30 of the inner panel unit 28 includes a generally flat web 52 and upstanding side walls 54, 56 provided along the opposite longitudinal edges of the web 52. The metal liner sheet 30 additionally includes marginal connecting means, such as an inwardly extending flange 58 and an outwardly extending flange 60 formed integrally with the upstanding side walls 54, 56, respectively. The inwardly extending flange 58 is provided with a longitudinal well 62 and a sealant-penetrating lip 64. The outwardly extending flange 60 is provided with a longitudinal rib 66. A sealant material 68 is disposed in a groove 70 provided between the longitudinal rib 60 and the upstanding side wall 56. The overall arrangement is such that a plurality of the inner panel units 28 may be erected in side-by-side relation to provide an interlocked sealed connection between adjacent ones of the inner panel units 28, as will hereinafter be more fully described.
Referring still to FIGURE 4, the foamed plastic core 32 is substantially coextensive in width and length with the metal liner sheet 30 and presents an essentially smooth foamed plastic core surface 72. The foamed plastic core surface 72 is generally parallel with the web, 52 and is spaced therefrom by a selected distance indicated at 74. The foamed plastic core 32 overlaps the outwardly extending flange 60. The inwardly extending flange 62, however, is exposed for the purpose of making the aforesaid interlocked connection with an adjacent one of the inner panel units 28.
The phrase foamed plastic used to describe the core 32, is intended to include those foamed-in-place thermal insulation materials produced from organic and inorganic constituents.
The foamed plastic core 32 can be produced by applying a metered quantity of an actively foaming mixture onto the web 52 of the metal liner sheet 30. The actively foaming mixture expands and cures to form the foamed plastic core 32. Suitable edge dams (not illustrated) can be provided to produce those clean opposite edges 32a, 32b of the foamed plastic core 32, illustrated in FIG- URE 4.
Referring to FIGURE 6, the actively foaming mixture is preferably poured onto the web 52 of the metal liner sheet 30. The preferred pouring technique will produce a foamed plastic core 32 having a generally uniform thickness, indicated at 76 in FIGURE 6, throughout its entire area and a generally smooth but textured foamed plastic core surface 78. It is desirable to modify the textured foamed plastic core surface 78, for example by calendering, to produce the aforesaid essentially smooth foamed plastic core surface 72 and to reduce the normal thickness 76 of the foamed plastic core 32 to the desired thickness 74.
Apparatus for calendering the textured foamed plastic core surface 78 is schematically illustrated in FIGURES 5 and 6 and includes a conveyor 80 which conveys the inner panel unit 28 beneath a calendering roll 82 driven by suitable drive means indicated at 84. The calendering roll 82 is supported by means (not illustrated) which permits the calendering roll 82 to be vertically adjusted at selected distances from the conveyor 80. Pressure is applied to the calendering roll 82 by means schematically illustrated by the arrows 86.
As the inner panel unit 28 passes beneath the calendering roll 82, the textured foamed plastic core surface 78 is compressed and leveled to produce the essentially smooth foamed plastic core surface 72. In addition, the normal thickness 76 of the foamed plastic core 32 is reduced such that the resulting essentially smooth foamed plastic core surface 72 is spaced from the web 52 of the metal liner sheet 30 by the selected distance 74.
As illustrated in FIGURE 7, adjacent inner panel units 28A, B may be sequentially erected in side-by-side, interlocked relation. The outwardly extending flange 60B overlaps and is interlocked with the inwardly extending flange 58A. The sealant-penetrating lip 64A penetrates the sealant material 68B to provide an essentially weather tight seal between the adjacent inner panel units 28A, 28B. The flanges 58A, 60B can be secured together by fasteners, such as self-tapping screw 108, positioned at spaced locations along the length of the flanges, as shown in FIG- URE 1.
The inner panel units 28A, 28B are secured to the girt member 26 by the aforesaid first fastening means 34 which penetrate the foamed plastic cores 32A, 32B and are disposed inboard of the essentially smooth foamed plastic core surfaces 72A, 72B and spaced from the corrugated facing sheets A, 30B. The first fastening means 34, for example, may comprise fasteners 112 of the type which are driven by an explosive charge and include a head portion 114 and a shank 116. When the fasteners 112 are installed, the head portion 114 is contiguous with the metal liner sheets 30A, 30B and the shank 116 pene- 6 trates the metal liner sheets 30A, 30B and the girt 26 of the building structural framework. Other suitable fasteners, such as self-tapping screws may also be used.
After the inner panel units 28A, 28B have been erected, the corrugated facing sheets 30A, 30B are sequentially erected in side-by-side, overlapped relation. The facing Sheet surfaces 46A presented by the valleys 42A, are in direct engagement with the essentially smooth foamed plastic core surfaces 72A, 72B. The second fastening means 38 are then applied to secure the corrugated facing sheet 30A to the building structural framework 22. The second fastening means 38 may comprise self-tapping screws 118 having a decorative head 120 contiguous with the valleys 42A and a threaded shank 122 extending through the valleys 42A, the foamed plastic cores 32B, the web 52B of the metal liner sheet 30B and into threaded engagement with the girt 26.
The adjacent corrugated facing sheets 30A, 30B also are disposed in overlapped relation. The overlapped edge portion 48A underlies the overlapping edge portion 50B and is in surface engagement therewith. The edge portions 48A, 50B are secured together by fasteners 124 which are spaced along the length of the adjacent corrugated facing sheets 36 as illustrated in FIGURE 1.
It will be appreciated by inspection of FIGURES 1, 2 and 7, that intermediate subgirt members, normally found in similar prior art insulated wall structures, are conspicuously absent from the present insulated wall structure 20. Such intermediate subgirt members are not needed and their omission reduces the materials cost and the erection cost of the present wall structure 20. Since intermediate subgirt members are essential to the assembly of similar prior art insulated wall structures, their omission from the present insulated wall structure 20 constitutes an improvement over similar prior art insulated wall structures. Furthermore, the use of intermediate subgirt members normally is accompanied by extensive areas of metal-t0- metal contact between the metal liner sheets and the metal facer sheets. Such metal-to-metal contact promotes through conduction of heat and results in a greater overall heat transfer coefficient. Consequently, the omission of intermediate subgirt members from the present wall structure 20 lowers its overall heat transfer coeflicient.
Alternative embodiments of the present inner panel unit are illustrated in FIGURES 8 and 9. Corresponding numerals will be employed to identify corresponding parts heretofore described.
Referring to FIGURE 8, there is illustrated an inner panel unit 88 consisting of a metal liner sheet 90 and a foamed plastic core 32 having an essentially smooth foamed plastic core surface 72. The metal liner sheet 90 includes a generally flat web 52 having marginal connecting means, such as a laterally outwardly extending male lip 92 provided with a sealant strip 94 and a laterally inwardly extending female lip 96.
Referring to FIGURE 9, there is illustrated an inner panel unit 98 consisting of a metal liner sheet 100 and a foamed plastic core 32 having the essentially smooth foamed plastic core surface 72. The metal liner sheet 100 comprises a generally flat web 52 having marginal connecting means, such as an upstanding male lip 102 and an upstanding female lip 104 provided along its opposite longitudinal edges. A sealant strip 106 is disposed within the female lip 104.
Alternative arrangements of the present insulated wall structure are illustrated in FIGURES 10 and 11. Corresponding numerals will be employed to identify corresponding parts heretofore described.
Referring to FIGURE 10, there is illustrated an insulated wall structure 126 consisting of a plurality of the inner panel units 88 secured to the structural framework 22 by the first fastening means 34 and a plurality of the corrugated facing sheets 36 abutting the foamed plastic cores 32 and secured to the building structural framework 22 by the second fastening means 38.
In this arrangement, the corrugated facing sheets 36 are reversed. The crests 40 and the overlapping edge portions 50 are in direct engagement with the essentially smooth foamed plastic core surface 72 while the valleys 42 are spaced from the inner panel units 88. The normal overlapping arrangement of the edge portion 48, 50 is also reversed. By reversing the corrugated facing sheets 36, the fasteners 124 (FIGURE 7) normally employed to secure the edge portions 48, 50 are eliminated.
Referring now to FIGURE 11, there is illustrated an insulated wall structure 128 consisting of a plurality of the inner panel units 98 erected in side-by-side interlocked relation and secured to the building structural framework 22 by the first fastening means 34; and a plurality of the corrugated facing sheets 36 erected in side-by-side overlapped relation in abutment with the foamed plastic cores 32 and secured to the building structural framework 22 by the second fastening means 38. The corrugated facing sheets 36 are reversed in the insulated wall structure 128 and are erected in the manner described above in connection with the insulated wall structure 126 of FIGURE 10.
