2 Claims. (Cl. 18934) My invention relates broadly to building structures and more particularly to a sandwich wall panel unit for building structures.

One of the objects of my invention is to provide a panel unit for building structures which is formed from cross-corrugated metallic roll material having associated therewith bOX-like sections and insulation material interposed between the cross-corrugated sheet and the boxlike sections.

Another object of my invention is to provide a con struction of sandwich wall unit for building structures formed from cross-corrugated metallic roll material with associated box-like sections secured to one side of the cross-corrugated material and spaced from at least two of the peripheral edges thereof enabling complementary sandwich wall units to be aligned with the cross corrugated material of adjacent units overlapping and with the box-like sections carried thereby abutting end-to-end for forming a continuous wall structure. Still another object of my invention is to provide a pro-assembled sandwich wall unit formed from crosscorrugated metallic roll material with an associated laminated structure on one face thereof including fibrous insulation material and perforated box-like sections enclosing the fibrous insulation material and forming a composite barrier for heat and cold and at the same time constituting a substantially acoustic absorber.

Still another object of my invention is to provide a sandwich wall unit including a cross-corrugated metallic roll sheet associated with box-like sections enclosing acoustic insulation material therein and wherein the boxlike sections have side portions which extend into contacting relation with the valleys of the cross-corrugations for spacing and aligning the box-like sections with respect to one side of the cross-corrugated material.

Another and further object of my invention is to provide a construction of sandwich wall unit in which crosscorrugated metallic roll material forms one side of the sandwich wall unit while a multiplicity of integrally connected box-like sections opening toward the cross-corrugated material form the other side of the sandwich unit with insulation material packed therebetween as set forth more fully in the specification hereinafter following by reference to the accompanying drawings, in which:

Fig. 1 is an elevational view of the sandwich Wall unit of my invention showing a multiplicity of box-like sections associated with one surface of a cross-corrugated metallic sheet and spaced from at least two of the marginal or peripheral edges of the cross-corrugated sheet;

j Fig. 2 is an end view of the sandwich wall unit shown in Fig. 1;

Fig. 3 is a transverse sectional view through the sandwich wall unit taken substantially on line 33 of Fig. 1;

Fig. 4 is an end view showing two sandwich wall units of the type illustrated in Figs. 13 aligned and overlapped one with respect to the other for forming a continuous partition or other building structure;

Fig. 5 is a front elevation view showing the manner in r 2,913,075 Patented Nov. 17, 1959 ICC Fig. 8 is an enlarged fragmentary perspective view il- 1 lustrating the manner in which the sides of the box-like sections are integrally connected;

v Fig. 9 is a fragmentary transverse sectional view through the sandwich wall unit on line 9-9 of Fig. 6, and showing particularly the manner in which the integrally connected side portions of the box-like sections serve as measuring means entering the valleys of the crosscorrugated metallic roll material which forms one side of the sandwich wall unit; and

Fig. 10 shows an application of the structure of my invention to an irregular or curved surface.

My invention is directed to a pre-assembled metallic building unit consisting of a cross-corrugated metallic roll sheet to which there is attached at one side a layer of fibrous insulation material and over which there is assembled a multiplicity of box-like sections enclosing the fibrous insulation material. The box-like sections are variously constructed to form either a solid metallic panel or are perforated to allow the entry of sound waves which are deadened and absorbed by the layer of fibrous insulation material interposed between the cross-corrugated metallic sheet and the open interiors of the boxlike sections. The box-like sections have side portions which are wider than the end portions of the box-like sections and which extend into the valleys of the crosscorrugated material and form measuring means or ribs which will seat into the valleys of the corrugations for spacing the box-like sections from the surface of the cross-corrugated material. The fibrous insulation material is attached to the surface of the cross corrugated material and to the inside surface of the box-like sections. The box-like sections are mounted in a position displaced from at least two of the marginal or peripheral edges of the cross corrugated material. This permits complementary panels to be assembled with each other with the cross-corrugated material of one panel aligned with and overlapping the cross-corrugated material of an adjacent panel and with the ends of the box-like sections abutting end-to-end. The overlapping portions of the cross-corrugated material of adjacent sandwich wall units may be fastened together to form a rigid wall surface which is insulated against heat and cold and which forms an acoustic barrier.

The sandwich wall unit of my invention has many applications and will withstand substantial stress in carrying loads for purlin and girth spacing. The structure of my invention may be completely pre-assembled at the manufacturing source and shipped in one complete panel unit for rapid installation in a manner which reduces the time of labor required for erection. The degree of skill necessary to install the sandwich wall unit of my invention is reduced to a minimum with accompanying reductions in building erection costs.

Referring to the drawings in more detail, reference character 1 designates the cross-corrugated metallic roll material with respect to which the box-like sections 2, 3, 4, and 5 are mounted. The surface of the cross-corrugated roll material 1 is covered by a layer of mastic or rubber base cement indicated at 6. The blanket of fiv, I 3 brous insulation material shown at 7 is laid over the cement 6 on the cross-corrugated roll material and adheres thereto. The open fronts of the box-like sections 2, 3, 4 and 5 are pressed over the fibrous insulation material 7 after the interior surfaces of the box-like sections 2-5 are givena coat of mastic or rubber base cement indicated at 8. This layer of cement 8 is very thin and does not block or fill up the perforations indicated at 9 in those structures which are prepared for acoustic insulation. Certain applications of my invention do not require perforations in the box-like'sections and in such instances the blanket of fibrous insulation material 7 serves simply asa barrier to heat and cold. In such instances the coating of the cement 8 is laid .over .a solid surface which is not perforated. Howeverfwhere the surface ofthe box-like sections is perforated,.as indicated in the drawings, the coating of cement 8 is sufliciently thin to provide the requiredadhesive properties for the fibrous insulation material '7, and the perforations 9 are not filled or closed. The box-likesections are formed in a continuous strip that is, the side portionsl!) and 11 of the box-like sections 3 and 4, for example, are integral and are bent upon themselves at the-edge 12. The side portions 10 and 11 he fiat in face-'to-face abutment, with respect to each, as shown more clearly in Fig. 9. The side portions 10 and 11 of boxlike section are wider than the end portions 141 and and serve as measuring means extending into the valleys of the cross-corrugated material 1 and making contact at the edge 12 with the surface of the cross-corrugated material 1 at the'valley. Thus the end portions 14 and 15 extend transversely of the corrugations of the cross-corrugated material 1 and establish tangential contact therewith, while the side portions 10 and 11 extend into the valleys and establish lineal contact between the edge 12 and the interior surface of the longitudinally extending valley.

The box-like sections 2-5 are mounted on each cross corrugated'metallic roll sheet 1, in a position displaced from the marginal or peripheral edges of the sheet, as represented in Fig. 1, leaving a longitudinally extending marginal portion 16 of the cross-corrugated sheet '1 free and a laterally extending portion 17 of the cross-corrugated sheet 1 free in each sandwich wall unit. These free portions 16 and 17 provide the overlapping areas necessary for installation of complementary units one with respect to another as represented in Figs. 5 and 6. In this arrangement the laterally extending cross-corrugated portion 17 of cross-corrugated'sheet 1 overlaps with the upper portion of a complementary cross-corrugated sheet 1' and the'ends14 of box-like sections 2, 3', 4 and 5 of sandwich wall unit 1', establishing abutting connection with theends 15 of box-like sections 2, 3, 4 and'S of sandwich wall unit 1. Similarly, the longitudinally extending free end 16 'of cross-corrugated metallic roll material 1 overlaps with'the marginal portion of the complementary sandwich wall unit 1" shown in Fig. 4 in the zone 16'. Under these conditions the longitudinal side 18 of box-like section 5 abuts with the longitudinally extending edge 19 of the box-like section 2' of the complementary adjacent sandwich wall unit 1", as shown in Fig. 4. The sandwich wall unit 1" is constructed in a manner identical with sandwich wall unit 1 and has a projectingmarginal or peripheral portion 16" serving as the overlapping connection for the succeeding or next adjacent sandwich wall unit. Thus the complementary sandwich Wall units are installed adjacent each other with the cross-corrugations of one unit interfitting with tions.

the cross-corrugations of a preceding unit and with the ends and edges of the box-like sections abutting end-toend or side-to-side for insuring a rigid self-sustaining structural assembly. The cross-corrugated overlapping portions of the complementary sandwich Wall units may be fastened together by the insertion of self-threading screws introduced through openings pierced into the overlapped portions of the cross corrugated surfaces.

Fig. 10 illustrates one of the applications of the structure 'of my'invention to a curved surface. Because of the fact that the sides 10 and Marc free to yield outwardly from the integrally interconnecting edge 12, the box-like sections are free to be adjusted .to angularposi- The fact that the cross-corrugated roll may be laterally conformed to any irregular 'or curved surface, coupled with the fact that the fibrous material is flexible, and the fact that the box-like sections may be canted to dilferent angles, permits the application of the composite structureof my invention to curved orirregular surfaces as represented in the schematic view-of Fig. 10. Thus the material may be .used as a tank'covering as well as a building partition.

1 have found the panel structure of my invention highly practical and successful in installation and use and while I have described my invention in certain preferred embodiments, I realize that modifications may be made and I-desire that it be understood that no limitations upon my invention are intended other than may beimposed by the scope of-the appended claims.
