4 Claims. (Cl. 189-34) My invention relates to an insulated panel adapted to be used in building the walls, or the roofs, of various enclosures, such as heated or cooled chambers, or of the walls or roofs of ordinary buildings or wherever lightness, rigidity and minimum heat transfer are required.
One object of the invention is to produce an improved panel of the type set forth.
In order to minimize the cost of fabrication of individual panels and the cost of assembling or mounting them to form the desired enclosure, the panels should be made relatively large. But, if panels of this type are made relatively large, they will sag and warp even though they are made of a relatively heavy gauge metal.
It is therefore a further object of the invention to produce an improved panel which can be made relatively large and of relatively light gauge metal, but which will not sag or warp.
A still further object is to produce an improved panel which can be mass-produced and which is interchangeable, side to side and end to end whereby production and assembly costs are reduced.
The full nature of the invention will be understood from the following specifications and the accompanying drawings in which:
Fig. 1 is a reduced, highly diagrammatic top plan view of the two panels showing one embodiment of my invention only the outline of the panels and the outline of only some of the parts inside the panels being shown.
Fig. 2 is an end elevational view looking in the direction of line 22 on Fig. 1.
Fig. 3 is an enlarged, exploded, vertical, sectional view looking in the direction of line 33 on Fig. 1.
Fig. 4 is similar to Fig. 2, but showing a second embodiment of the invention.
Fig. 5 is similar to Fig. 3, but showing the panels of said second embodiment.
Fig. 6 is a fragmentary, enlarged, sectional view taken on line 6-6 on Fig. 2.
Fig. 7 is a vertical, sectional view, showing the panels of Fig. 5 in their assembled position.
Fig. 8 is an enlarged, perspective, exploded view showing the assembling and reinforcing members which are shown at the ends of Figs. 3, 5 and 7.
Fig. 9 is a diagrammatic, isometric view illustrating the manner in which the panels of my invention resist the stresses to which they are subjected in actual use.
In the embodiment of Figs. 1 and 2, each panel is formed of an outer sheet 16 and an inner sheet 18 with insulation 20 therebetween. The ends of the panels are closed by means of plates or sheets 22, which are flanged outwardly at 23 and are secured to the edges of sheets 16 and 18 by rivets or the like 24, as best shown in Figs. 2, 4 and 6. Sheets 16 and 18 may be made of aluminum or of stainless steel or other material.
In the embodiment of Fig. 1, one end 28 of outer sheet 16 of panel A is bent downwardly and laterally inwardly and cooperates with the corresponding upwardly and laterally outwardly bent end 30 of sheet 18, to form an upper,,reduced, overhanging pocket which is generally referred to be reference character 32. The adjacent end 34 of outer sheet 16 of adjacent panel B is bent downwardly and laterally outwardly and cooperates with corresponding upwardly and laterally inwardly bent end 36 of inner sheet 18 to form a pocket which is generally referred to by reference character 38 and which, when the panels are assembled will underlie overhanging pocket 32 as shown in outline in the center of Fig. 2. Since the junctions of all panels of this embodiment are the same as that described for the adjacent, overlapping junctions of panels A and B, it is believed unnecessary tov further illustrate or describe this particular feature.
In order to make it possible to produce relatively large panels of relatively light gauge sheet metal which will not sag or warp, I have devised a novel construction which resembles a truss in its rigidity and its torque resisting characteristics. According to my invention, I place reinforcing and clamping blocks 40 of Fig. 8 in the corresponding sides of panels A and B and I place similar blocks 42 in the opposite corresponding sides of said panels. From Fig. 8 it will be seen that blocks 40 and 42 are L-shaped and from Figs. 2 and 3, it will be seen that blocks 40 and 42 assume the same relation in the assembled panels that they do in Fig. 8. In other words, the left hand overhanging portion of block 40 is enclosed in upper, overhanging pocket 32 of panel A and the right hand underlying portion of block 42 is enclosed in underlying pockets 38 of panel B. Blocks 40 and 42 are provided with through holes for receiving bolts 46 which secure the overlapping sides of panels A and B together. The inner ends of bolts 46 may pass through suitably spaced angles or girders 48 which constitute a supporting frame for a wall or roof built of these panels. It will be noted that the outer ends of bolts 46 threadedly engage nuts 50 which are placed in recesses which are spaced from outer sheets 16 so as to produce an unbroken, leak proof outer surface and to reduce thermal conductivity to the outer sheet. By this arrangement bolts 46 can be threaded into the nuts after being passed through angles 48 and blocks 42. It will also be seen that the edges 52 and 54 of outer and inner sheets 16 and 18 of panel A engage groove 56 in block 40 and that corresponding edges 58 and 60 of inner and outer sheets 16 and 18 of panel B engage groove 62 in block 42. Therefore, when the panels are assembled, as shown in Fig. 2, the marginal portions of inner and outer sheets 16 and 18 which terminate in edges 52, 54, 58 and 60 will be clamped between the flat surfaces 64 and 66 of blocks 40 and 42.
In order to minimize metal to metal contact and, hence, heat transmission, I place a heat insulating sheet 70 between blocks 40 and 42 and the contiguous portions of sheets 16 and 18 as shown in Fig. 3.
In order to tension outer and inner sheets 16 and 18 in the direction of their widths, I provide spaced turn buckles each of which consists of a hub adapted to abut a block 42 and a screw 74 threadedly engaging hub 72 and having a flange 76 for abutting a block 40. Blocks 40 and 42 are provided with through holes 78 through which a screw driver, or other tool, may be inserted to I turn screw 74 in a direction to spread blocks 40 and 42 apart and thus tension sheets 16 and 18. The provision of holes 78 makes it possible to tension the sheets of each panel after it is completely formed and after one side of such panel has been securely clamped to the previous panel.
It will be seen from Fig. 1 that blocks 40 and 42 and turn buckles 72 are placed at intervals along the length of the panels, the distance between adjacent blocks being determined by the requirements of each case.
The construction thus far described is operative, but, for certain cases, it is desirable further to reinforce the construction-Hy meansofrigid angles 80 which can extendthelength of the panel'or which may be long enough to be engaged by the spacedfadjacent blocks 40 and 42.
