Filed June 4l, 195%, Ser. No. lde 6 Claims. (Cl. 1559-34) The present invention relates to building materials and, more particularly, relates to improvements in curtain wall material and to a method for making curtain wall material.
It is an object of the present invention to provide an improved curtain wall structure.
A further object of the present invention is Ito provide an improved method for making curtain wall material.
Frequently the walls of modern buildings are constructed of curtain wall material, which usually includes an outer panel, which faces outwardly of the building, an inner panel, which faces the inside wall of the building, and insulating material, which is received between the two panels. The panels are frequently formed of steel and sometimes of a composite material called porcelain enamel glass fused on steel). Such lcurtain wall sections are used to form the walls of modern buildings which are so constructed that the sections forming the walls do not carry substantial stresses, the steel or other structural members of the building7 being so designed as to support the weight of the building.
Thus, such curtain wall sections may be constructed, for example, of a one-inch thickness as compared to the twelve-inch thickness of walls in older types of buildings. In present-day curtain wall sections, the outer panel is connected to the inner panel by means of a plurality of bolts or other metal fastening means which pass through flanges at the edges of the panels or, in some cases, through the centers of the panels. Such fastening means allow a heat loss from the building because of the known property of metal to quickly transmit heat, the heat passing from the inner panel through the fastening means and the outer panel to the outside. Also on hot summer days heat will be conducted in the opposite direction.
It is, therefore, an object of the present invention to provide an improved curtain wall structure which will allow only -a minimum heat transfer.
Frequently in -the making of curtain wall material, moisture is allowed to condense between the panels of a particular section of curtain wall material reducing the insulating ability of the insulating material received within the panels.
It is, therefore, a further object of the invention to provide an improved method for making curtain wall material which cuts down the amount of moisture available for condensation within the curtain wall material.
Still another object of the present invention is to provide curtain wall material Iand a method for making curtain wall material which has more perfectly flat outer surfaces, it being understood that frequently the panels making up the curtain wall material are bowed outwardly or inwardly in their centers and have further imperfections in their shape as a result of the operations necessary to form the panels.
Still further objects will become apparent as the description proceeds.
The full nature of the invention will be understood from the accompanying drawings and `the following description and claims.
FIG. l is a transverse sectional view of a section of curtain wall material constructed in accordance with the present invention.
FIG. 2 is a fragmentary perspective View of curtain wall material identical to that illustrated at FIG. 1 except that the insulating material is of a different type, FIG. 2 also illustrating certain apparatus used in the practice of the method also forming a portion of the present invention.
FIG. 3 is a fragmentary transverse sectional View of the structure of FlG. 2 bu-t also illustrating certain further apparatus used in the practice of the method which forms a portion of the present invention.
Referring now to the drawings, our invention comprises an outer panel lil made up of a rectangular portion 19A and a perpendicular flange ltlB which extends around the edge of the rectangular portion 13A. An inner panel 1l having a rectangular portion llA somewhat smaller than the rectangular portion liiA is also provided with a perpendicular flange llB which extends around the edge of the rectangular portion 11A. The flange of the inner panel l1 is nested within the ilange of the outer panel lil with the concave portion of the inner panel facing the outer panel.
A large section l2 of insulating material is received within the chamber formed between the two panels and serves to prevent the transfer of heat from one of the panels to the other panel. A plurality of angle-shaped spacers l5 formed of insulating material are received at and adjacent the corners of the panels lli and ll and vfunction to space the flange `llB of the inner panel from the iiange lill? of the outer panel and from the rectangular portion ltPA of the outer panel. As can be noted from an examination of PEG. 2, the spacers 15 are located only at near the corners of the panels and do not extend a substantial distance from those cor-ners.
After the panels lll and l1, insulating rnaterial l2, and the spacers 1S have been assembled as illustrated in FlG. l, a bead of caulking compound 16 is placed between -the flanges ltlB and 11B by means yof the caulking gun 17 illustrated in FlG. 2, or by any other suitable means, in such a manner as to secure the flanges together. Since the caulking compound l5 is 'the only element holding the parts in the relationship illustrated in FiG. l, it is necessary .that the caulking compound securely adhere to the mutually facing surfaces of the flanges lilB and 11B. We have found that polysulflde polymer caulking compound or any adhesive compound having similar properties Will accomplish the secure adhesion necessary to hold he panels lll and ll together. Such polysuliide poly-mer caulking compound is cornmercially available and can be applied in -a liquid state and will cure to a flexible, firm rubber.
it should be understood that the insulating material l2 can be any type `of suitable insulation and does not have to be of the particular rigid type of insulation 12A described below.
Referring now more particularly to FIGS. 2 and 3, our process for making curtain wall material will now be described. The panels lll and ll, the insulating `material, and the spacers l5 are assembled as above described. The insulating material 12A used in our method should be of a type, such as honeycomb or foam glass insulation, which has a large number of cavities therein yet has iirrn, fiat outer surfaces 2@ and 2l for a purpose which will become evident.
rCaulking compound le is then placed between the mutually facing surfaces of the -lianges 10B and 11B so as to secure the flanges together and so as to seal the chamber formed between the panels l!) and l1 within which the insulating material 12A is received. We have found that the above-mentioned polysuliide polymer caull-ing compound will accomplish the sealing of the chamber necessary to our method. In placing the caulk- 8,1 o La ing compound, a tube 22 is sea-ted therein so as to provide communication between a vacuum pump 25 and the chamber containing the insulating material 12A.
A partial vacuum is Ithen created within the chamber by means of the vacuum pump 25, which results in moisture being removed `from the insulating material 12A so as to dispose of the reduced insulating ability resulting from such moisture condensing Within the curtain Wall section. A further result of the exhaustion of air from the chamber is that the rectangular portions 19A and 11A of the paneis are drawn into irm Contact with the flat surfaces 2@ and 2l of the insulating material 12A, whereby the panels are provided with Amore periectly -ilat outer surfaces. rThe vacuum pump 25 is then removed and the tube 22 closed oi by a plug or other suitable means 'The abutting surfaces of the panels and insulating ma-terial may or may not be coated with a contact type cement thereby helping to maintain the panels fiat in the `event of a `loss of vacuum.
The above described process could be practiced with a non-rigid slab or insulating material or even with no slab of insulating material if the spacers are so proportioned and arranged as to perform the supporting ,function or" the slab of insulating material 12A. lFor eX- arnple, a plurality of spacers, lin addition to the spacers 15, might be located at spaced points between the two `panels 1G and 11 -to resist the eect of the vacuum to draw the panels together. ln such an arrangement, if no slab of insulating material is used, the vacuum would provide the needed insulation.
The invention claimed is:
