Ratner, Parsippany, and Robert Slater, Morristown, NJ., assignors to The Marco Company, a corporation of New Jersey Filed Mar.. 19, 1958, Ser. No. 7225i@ Claims. (Cl. 1S9--34) This invention relates to new and useful improvements in prefabricated double-walled building panels that are light in weight, exhibit high strength, and have excellent insulating properties. The panels may be readily and firmly secured to one another' or other structure or may be used as single units. The panels may optionally be provided with novel interior beams or various other grid networks.

lt would be beneficial for the building industry to have available economical prefabricated panels of spaced double-walled construction that can readily be joined together or to other building structure by unskilled laborers, have strength, simplicity, durability and which may have, if desired, readily insulated airand/or watertight joints.

lt is an object of this invention to provide prefabricated building panels of spaced double-wall construction that may be readily manufactured by using simplified integral extruded beams for the perimeter and optionally a grid network of integral extruded means onto which may be laminated the spaced walls or surface sheets.

It is another object of this invention to provide prefabricated building panels of spaced double-wall construction formed from extrduded integral beams that may readily 'oe secured to one another or other building structure by interlocking arrangement of the leading and/or trailing perimeter beams.

It is a further object of this invention to provide prefabricated panels of the character described that will have numerous versatile applications in the building industry including, but not limited to, exterior wall panels, interior .wall panels, skylights, canopies, and decorative panels.

It is an additionalobject of this invention to provide prefabricated panels of the character described that may readily be filled with various types of insulating material during fabrication.

It is also an object of this invention to provide prefabricated panels of the character described which may readily be secured together with insulation positioned at the sealing joint.

lt is another object of this invention to provide means .to secure prefabricated panels of the character described framework being formed to interlock so that successive panels may be securely attached to one another without additional elements.4 We have further found that the perimeter framework maybe securely interlockedto an interior grid*V system by a novelarrangement offlanges provided "on the interior surface-lof the perimeterbeams and 'corresponding notches cut inthe interior grid beams. Moreover, the interior beams are interlocked to one another in the same novel manneLffW/e have also found various ways in which` to mount our lnovel panels.

Referring to the drawings in detail, this invention as illustrated is embodied in building panels that may be used for vertical or horizontal, exterior or interior walls and various means for mounting the panels.

A vertical plan view is shown in FIG. l wherein a group of three panel members 2l are shown attached to each other with a plain exterior perimeter andwith the design of an M shown on the face of one of the panel members. Any design may be chosen or the panels may be plain.

FIGS. 2 to 7 show the details of the interior of these panel members and certain modifications, FIG. 2 being a section running through the trailing and leading edge of a panel member and showing the detail of the beams used in the construction thereof. The leading edge is formed of an integral extruded single beam 22 which includes a primary member 23 and at each end thereof a sheet sup-porting flange 24 and a 'sheet guarding flange 2.6, adapted to receive in the channel therebetween the associatedsurface sheet 27'. Intermediate of the sheet supporting flanges 24 and also integral with the primary member 23, is a pair of spaced internal locking flanges 28, transverse tothe primary member and generally parallel to the -sheet flanges 24, 26. The internal locking flanges Iat their free end are provided with angular flanges 29 disposed toward one another. On theV opposed site of the primary member 23 at one end thereof and integral therewith is an inner guide flange 3l 'and at the opposed `end a long interlocking flange 32 provided at its free end with an integral Ushaped member 33. At the free end `of the U-sha'ped member is an enlarged head 3e adapted to optionally receive a. vinyl gasket 35 for sealing purposes. nGihe gasket is provided with an open space 37 to insure flexibility.

At the trailing end of said pa. el member isyan integral ,l extruded single beam 38 which is pro-vided with aprimary Vmember 23,. sheet supporting .flanges 24, sheet guarding .flanges 2d,.surface sheets 27, internal locking flanges 2S and yangular flanges kZhwhich `are similar to' the same members on the leading beam and have been given the same reference numerals. However, on the opposed side of the primary member 23 and extending outwardly from the panel is an inner base flange 39 on one end and a short interlocking U-shaped flange 41 at the other end, one leg of the U being formed by a portion of the primary member 23.

Within the body of the panel member running both parallel and transverse to the leading and trailing beams are interior grid beams of two lengths, the spanning ibeams 42 and the short beams 43, both of identical crosssection land which are provided with a regular l'-beam section having a primary member 44 with top and bottom plates and on each side of the primary member are a pair of spaced internal locking flanges 47, each of which is provided with an angular flange 4S disposed toward the other angular flange on the same side of the primary member. These internal locking flanges 4-7 and angular flanges 4S will be recognized as similar to flanges 28 and 29 of the perimeter beams except that the flanges of the internal beams project in beth directions from the primary member and the flanges normal to the primary member are shorter than those provided in the perimeter beams, these relative lengths being practical but having no patentable significance.

A modified interior beam 49 is shown in FIG. 3 and includes a shorter primary member 51 which is terminated at top and `bottom by locking flanges 52 which are provided with angular flanges 53 similar to those described previously. FIG. 3 also shows a plain perimeter beam 54 which has primary member 56 provided with sheet supporting flanges 24, sheet guarding flanges 26, internal locking flanges 28 and angular flanges 29 which -are similar to the same numbered elements of the leading and trailing beams. It will be appreciated that the interior sides of all the perimeter beams described hereinbefore are identical and that the difference in the beams is concerned with the exterior face. Each of the locking flanges 28, however, is provided with a small boss 57 facing the other boss and spaced slightly from the primary member 56 so as to receive and retain an angle corner clip 58.

All of the beam members and associated flanges are extruded members although the sheet guarding flange 26 on all perimeter beams extends in the same plane as the primary member 23 (or 56) when extruded, as shown in FIG. 5. After the sheet has been placed in position on the supporting flange 24, the guard flange 26 is rotated into guarding position parallel with the sheet surface so as to hold it in position, this rotation being facilitated by notch 59 to avoid breaking the flange. The surfaces of these flanges facing toward the sheets are serrated as at 61 so as to better grasp and hold the sheet surfaces, this being a desirable but not necessary feature of the invention.

The beams in FIGS. 1 to 6 are all integral one piece metal beams which have been found economically and structurally desirable in most instances. However, FIG. 7 sho-ws a ymodified three piece interior beam 62 which is desirable in certain instances as discussed hereinafter. This beam comprises two identical metal extrusions 63 which are joined together by a plastic extrusion 64. The metal extrusions are in the shape of a T-beam and include a primary member 66, a sheet supporting flange 67, an enlarged head 68 and a pair of oppositely disposed transverse locking flanges 69 provided at their free ends with an angular flange 71. As will be noted from the drawing, the plastic extrusion is shaped to receive the enlarged heads and terminal section of the primary members 66 so that beam 62 is functionally the same as interior beams 42 and 43. Moreover, any of the other integral one piece beams could be made in the same manner. v

in constructing individual panels, the four selected perimeter beams are first cut to proper lengths and mitered at the ends inwardly from the primary member. There is no need to miter outwardly from the primary member unless two interlocking beams were being joined at a corner. This is possible but will not happen generally as the leading and trailing beams will appear on 0pposed edges in spaced parallel relationship as lfar as a single panel is concerned. The mitered corners may be secured together by many ways including welding (not shown) or an angle corner clip 58 may be slid into position on one beam (FIGS. 3 and 4), and the other corner beam then slid into position along the clip of the beams that have been extruded with bosses 57. The beams may then be secured to the clip by set screws, indentations, edges, etc. Thereafter, the spanning interior beams 42 are cut to the proper length, notched and positioned. As will be noted in FIG. 2, the interior beams 42 and 43 are provided with notches to engage the locking flanges of transverse beams, Whether on the perimeter or in the interior. The notches are angularly cut in the beam end with a long wall 72, an end wall 73 and a short wall 74. There are a pair of notches at each end of a beam at an angle corresponding to the angular disposition of the terminal angular flanges 29, 48, 53, i.e., pointing toward each other. The angularly disposed notches thus form a neck at their closest point which defines an enlarged head 76 that engages the corresponding angular flanges of a transverse beam. The notches are cut so that the associated angular flange will rest snugly on the short notch wall 74, i.e., the two walls closest one another, whereas the end wall 73 and the long wall 72 are cut larger than the associated flanges so as to permit rotation of the interior beams into the proper engaging positions.

The head 76 has its ears 77 considerably shortened from their potential length. This is necessary in order to easily engage the head and notches with the angularly disposed flanges without being forced to slide them into engaging position from an open end. With the notches cut as shown, if the notched beam is rotated about 40 about its longitudinal axis from its ultimate engaging position, the head 76 can be inserted into the space between the angularly disposed flanges so that on reverse rotation to the engaging position, the head, notches and angular flanges will be engaged as shown. The top and bottom plates 46 are flush with and abut the sheet supporting flanges 24' of the other beam and therefore there can be no relative movement between the two transverse and engaged beams.

The short interior beams 43 are notched and positioned between the spanning beams 42 in the same manner as the spanning beams are placed between the perimeter beams. The spanning beams 42 are shown running the long way in the building panels in FIG. l, as it is deemed desirable for appearance to run them vertically. The short beams thus are horizontal and are shown in a staggered pattern for increased strength. However, the directions and staggering of the beams are merely a matter o-f routine design choice.

After the grid network has been finished, an adhesive will be placed on the top and bottom plates, sheet supporting flanges, and sheet guarding flanges and a proper sized sheet placed on the top and bottom panel surface. The guard flanges 46 will then be rotated until they are parallel with and firmly contact the sheet to make a leak proof joint.

As shown in FIG. 2, the left panel (only trailing edge shown) was first placed in position and` attached to the wall by means of screw 78. Thereafter, the right panel (shown completely) is positioned by first placing the free end 34 of U-shaped member 33 within the U-shaped member 41 of the trailing edge. At this point the free right panel will be angularly disposed relative to the attached left one. However, the right panel will then be rotated into the position shown in FIG. 2, after which it will be secured into that position. A strip of insulation 79 is shown in the space defined between the two succeeding panel members although it may be left out, if desired. Another optional feature is the vinyl gasket 36 with the open space 37 (FIG. 6) which provides exibility to make a positive seal between the succeeding panels and has been found to be very desirable. This could, of course, be aranged on the free end of member 41 in the same manner.

It will be readily appreciated that the U-shaped members 33 and 41 provide a loose joint between succeeding panels which permits expansion and contraction. FIG. 8 yshows a modified joint which will also permit expansion. The trailing beam is provided with an elongated female member 81 adapted to receive the head 82 of a male member 83 which can be released only when one pane1 is not in alignment with the other and yet permits expansion or contraction, one leg 31a overhanging the other leg Sib.

It is not necessary that the trailing edges of the building panels be attached to the wall as shown butit can readily be done by screws or otherwise, if so desired. Moreover, various other ways can be utilized to maintain proper aiignment of successive panels. In mounting several panels in alignment, the associated leading and trailing beams will normally be used at all joints between panels. However, the plain beams 54 will be preferred at the final perimeter edge lof the larger structure, for example, as shown around the perimeter of FIG. l. In fact, it is possible and will undoubtedly be desirable in many instances, to have plain beams around all four sides of a single panel. Moreover, the interlocking trailing and leading beams may be used on one, two, three or four sides of a single pane-l, depending on the interlocking arrangement that is desired with other similar panels or mounting structure. lt is possible with these beams to construct a panel having an aperture, using plain beams 54 to deline such an aperture and, of course, cutting the surface sheets accordingly.

FIG. 9 shows a further modilied panel 84 having double air spaces i'between three surface sheets 27 instead of two as shown otherwise. The perimeter beam 87 is shown as a single extrusion that represents practically a double beam. However, the interior beams and their notching engagement are identical with the interior beams 42 and 43. It will be noted that the middle surface sheet is maintained in a fixed position by the interior beams from both sides. Although the modified beam 87 is shown plain, it will be readily appreciated that it may have an exterior shape adapted to interlock in the same manner as beams 22 and 3S.

FlG. l shows a modiiied perimeter beam 88 pro-viding a modified locking -or guarding means for the surface sheet 27. This beam does not have guard lianges but instead has anenlarged end section 89. The enlarged section carries a sheet support flange 91 and a deep narrow notch 92that is provided with a series of bosses 93. The surface sheet will be sized to rest on the support flange 91 but not to cover the notch 92. After the surace sheet is in position, a locking angle member 94 provided on an arm 96 with indentations 97 to correspondl withbosses is inserted and forced into the notch to. guard the surface sheet. tions 97 to securely maintain the position .of the angle member with arm 98 being parallel and adjacent to the surface sheet. Obviously, various other means could be used to secure arm 96 in the notch 92 or to secure the surface sheet to the perimeter beams.` In fact, it will be sufficient in many instances merely to Vsecure the surface sheets to the sheet supporting flange withoutany guard, in which case the sheet will generally be flush with the exterior perimeter beam wall. u f

` The various beams used in this construction can readily be made of integral aluminum extrusions whichrwe have employed with success. The surface sheets may be made of fiberglass reinforced polyester plastic which has excellent insulation and light transmission characteristics.

The bosses 93 fit into indentaj However, our concept is not limited to the materials from which these structures are formed. The beams might 'be brass, steel, plastic, die castings, etc., whereas the surface sheet might be glass, aluminum., other plastics, copper, steel, etc. Moreover the surface sheet may be secured to the grid by means other than conventional adhesives.

rl`he insulating value of these units is quite high but may be improved to even greater etiiciency. Most of the heat transfer through the building panel shown in FiG. 2 will be from one sheet surface to the other through the metal gridwork used to reinforce the panel. There are several ways of avoiding most of this heat `loss. As shown in FIG. 3 the interior grid beams 4may be shortened so that they do not touch either surface sheet of the panel. FlG. 7 shows an interior beam having discontinuous metal pieces separated by plastic. FIG. 9 shows a double air-space between the two `surface sheets and the top and bottom interior beams could be arranged so as not to be in vertical alignment. l'tn these ways heat transfer through the panels will be reduced to negligible levels.

Another way of reducing heat transmission is to eliminate the interior grid beams entirely, utilizing lonly the perimeter beams as shown in FEiG. 8. Whether this is done or not, depends, of course, somewhat upon the size ot the panel and on the ultimate load to be carried thereby. Where the interior grid beams completely span the distance between the surface sheets, an insulating material may be used between the grid beam and the surface sheet to reduce heat transmission.

in all ol these modilications, regardless lof* the size, shape, presence or absence of the interior grid'beams, the interior of the panel maybe filled with insulating material and the panels are quite adaptable to be filled with expanding types of insulation which greatly expand after introduction of the insulating material into a space and later become set, eg., various foamed insulations. Sheet insulation could, of course, he used fairly easily if the grid beams are absent or shortened but free owing types of insulation are preferred when full grid Ibeams ar: present. course, be used in the void space formed by the interlocking anges of succeeding panels. v

FlG. il shows a schematic outline of a building panel 21 which rests against -a building wall 99, extends from the door itil to the ceiling 102 and is secured in position by angle members 163 which can be easily secured to the floor and ceiling by nails or otherwise. b

FIG. l2 shows another desirable method vof utilizing the buildingpanel of this invention, i.e., as a sunshade. A cantilevered T-beam 137 is shown in cross-section-of its length as it would project outwardly from the wall of a building and. is provided with .a bottom plate 138 or ange which is notched at 139 to provide engagement with the inner ,guide ange 31 of the framing-member 22 of the panel 21. Extending in opposite directions from the primary member or leg 142 of the T are L-shaped arms 141 forming integraily with the leg 142 a pair of upwardly extending channels. Thepanel 2l is so arranged that the U-shaped member 33 fits into the larger channelV formed by arm 1411 and bears on this arm to and in supporting the weight of the panel on the cantilevered T-bearn and the'guide ilange 31 restsupon notch 139 of lthe bottom plate'. A cap member 143 is then secured to the top of the I-beam and extends over the interlocking U-shaped member of the building panel'to lock the panel into its position.` twill be appreciated that another panel member could be inserted onthe right side of the I-beam in the same manner as shown here to the left. In this instance, the remaining three perimeter beamsrof the panel member will 'likely be piain beams 'simila'rto i beam 55s shown in llG;,3.

Many other uses lof these nove-l buiiding panels `will be suggested to those in the art such as skylights, canopies, v

These samer type insulations could, ofv

roofing, marquis, etc. and are deemed to be within the scope of this invention.

In the embodiment of FIGS. 3 and 12 is shown in elevation a modied beam member 49 of which the typical section is shown in FIG. 3. In the beam member 49, as above described, the conventional plates or llanges of the I section are omitted to -avoid conduction 'of heat through the grid beam structure from one surface sheet to the other at opposite faces of the panel. In order to prevent endwise movement of the member 49 after being rotated, as above described, into the locking position shown in FIG. l2, the primary member or web 51 is extended beyond the notches 72, 73, 74 to form head 147 of generally rectangular form and of such length as to abut the primary member or web 23 of the leading beam 22 on the surface thereof between the locking ilanges 28. The grid member 49 thus becomes locked between the primary member 23 and the angular flanges 29. This form of the grid members may be used in different combinations with the other embodiments shown and described, e.g. in FIG. 3.

'lt also will be understood from a consideration of FIGS. 2, 8 and l2 that the guide flange 31 is disposed inwardly rel-ative to the adjacent face of the panel with respect to the base ange 39 of FIGS. 2 and 8 or the llange carrying notch 139 of FIG. l2, having regard to the disposition of the free end 34 of the U-shaped member of the long interlocking flange 32 within the U of the short interlocking llange 41. This arrangement of the flanges secures the requisite interlock and holds the trailing and leading ends of the panels together, since these adjacent ends of the two panels cannot move apart to an undesirable extent when they yare disposed in the positions relative to each other as in FIGS. 2, 8 and l2, although provision is made for movement for expansion and contraction parallel to the plane of the panel, as above mentioned.

It will be appreciated that the building panels described herein have several novel features including the provision of external interlocking tlanges on the leading and trailing beams so Ithat two successive panels may be easily and readily attached to one `another by unskilled labor. These external flanges may be altered within the scope of this invention as long as successive panels are readily interlocked to one another. This external interlocking feature may be used independently of the particular internal grid system here shown, i.e., the external fea-tures are possible without any interior grid system or with another type grid system (e.g., the internal grid systems of our copending application, Serial No. 645,706, iiled March 13, 1957, now Patent No. 2,969,618). In fact, as shown in FIG. 8, entirely independent panels may be mounted within the interlocking perimeter beams disclosed herein.

The particular internal grid system ydisclosed herein is also novel and can be used with or without the exterior interlocking flanges shown here. It is possible, eg., to make a single building panel having an internal grid system 'as described herein but with all perimeter beams being plain like beam 54 or the perimeter beam surfaces may be formed in other desired shapes, e.g., as shown in our aforementioned copending application.
