Halbert Road, Bethesda, Md. 20034 Filed Sept. 15, 1964, Ser. No. 396,592 4 Claims. (CI. 52-70) ABSTRACT OF THE DISCLOSURE A set of panels of isosceles triangular shape, each panel being of substantially the same size and shape, each panel having securing means on each side so that the panels are standard and interchangeable with panels of other sets of panels. A plurality of sets of panels being assemblable to form side walls and roofs of polygonal buildings.

This invention relates to buildings and more specifically to demountable or portable buildings of a type which is formed of a plurality of similar panels assembled readily without the aid of special tools and which may be formed into buildings of various configurations.

Such a building may be used by a construction company since it may be readily carried to a construction site by truck and quickly assembled at the site at which the company is busy, and, moreover, it may be removed about the site readily, after it has been assembled, by means of a crane.

Such a building may also be very desirably used in inaccessible places of the world by explorers or the like, since the units may be transported to their place of erection by, for instance, a helicopter, and after arrival may readily and quickly be assembled into a strong, tight building.

It is an object, therefore, of the present invention to provide a plurality of panels which may be assembled quickly and easily to form a building.

It is a further object of this invention to provide building panels of such light but strong construction that while they may be readily transported because of their lightness, the resultant building will be sufliciently strong to withstand the rigors of adverse weather conditions and may in fact be used as a permanent structure.

Other and further objects and advantages of the present invention will become apparent from the following specification taken with the accompanying drawing in which like reference characters refer to similar elements in the several views and in which:

FIGURE 1 is a perspective view of a four-sided building according to the present invention.

FIGURE 2 is a perspective view of a six-sided building according to the present invention.

FIGURE 3 is a plan view showing the framing of the floor for a five-sided building.

FIGURE 4 is a view similar to FIGURE 3 showing the floor for a six-sided building.

FIGURE 5 shows a roof panel from the underside.

FIGURES 6 and 7 each show one of the two forms of side panel used, showing the inside surface of the panels.

FIGURES 8, 9, 10 and 11 are fragmentary sections showing the connection between a side panel similar to that of FIGURE 7 to a roof panel similar to that of FIG- URE 5 in a triangular, square, pentagonal, and hexagonal building, respectively.

FIGURES 12, 13 and 14 show plan, elevation and section of a connecting element such as used. throughout the construction of the building;

FIGURE 15 shows diagrammatically the assembly for a three-corner building as it would appear if laid out flat.

FIGURE 16 is a fragmentary section taken at the upper corner of a building such as FIGURE 2 but showing the addition of a second floor in lieu of the roof.

FIGURE 17 is a section taken on line 1717 of FIG- URE 16.

FIGURE 18 is a section taken on line 18-18 of FIG- URE 17 and of FIGURE 16.

FIGURE 19 is a perspective view of an element seen in FIGURES 16, 17 and 18.

FIGURE 20 is a perspective view of a two-story hexagonal building according to the present invention.

FIGURE 21 is a diagrammatic section taken through a building according to the present invention adapted particularly to be lifted and moved from place to place by a crane or the like.

From FIGURES 1 and 2 it is seen that a building according to the present invention is made up of a series of panels 10, 11 and 12. Central panel 10 in each of these two figures is shown as including a door which, however, is not necessary in all such panels 10 as seen in the side panels 10 in FIGURE 2. Similarly, panels 11 are shown with a window and clearly the presence or absence of windows is not germane to any issue of patentability herein. The panels 12 are of slightly different configuration than panels 10 and 11 because of factors which will be discussed later.

The base or floor of the building of FIGURE 1 and FIGURE 2 are a square and a hexagon respectively which, in the exemplification being described, are eight feet on the side, though they may of course be of any other suitable dimension. The structure of the fioor or platform per se will be described below but is passed over for the moment in favor of describing the side walls and roof of the structure.

Referring to FIGURE 6, a panel 10 is shown from the inside where it is seen that the panel is bounded by structural elements 13, one along each side of an isoscles triangle. While the scantlings of the elements are not specifically germane to the issue of patentability, a frame element 13 of 1" X 4" dimension has been found to be useful, the 4" face being applied flat against a plywood panel element. Along one edge which as will appear later will be the lower edge of this panel 10, is a flashing element 14 which may be of any suitable material, and aluminum is suggested as a flashing material. Along the three edges of panel 10, connecting elements 15 are mounted. Elements 15 are similar to a hinge. The connecting elements are shown in detail in FIGURES 12, 13 and 14, and will be described below in referring to these specific figures.

Referring to FIGURE 7, We see a panel 11 which is formed of a sheet of plywood of similar thickness and of the same configuration as that used for panellll. Panel 11 is bounded by strips 16 which may conveniently have a scantling of 2" x 3", and to which connecting elements 15 are also secured that are preferably both identical to and complementary to the elements 15 secured to frame element 13 of FIGURE 6. Frame elements 16 are applied with their 3" wide faces against the plywood. On two edges of panel 11, a flashing 17 is provided which, as will be seen below, will overlap the edges of the adjacent panels 10.

Roof panels 12 differ from the panels 10 and 11 because they have preferably more acute apex angles to form the peak of the roof. Along one edge of a triangle there is a structural element 18 which may conveniently be a piece of 2" x 3" wood with its 2" face toward the plywood of the panel itself. The plywood of the panel may extend in one direction, below element 18 in FIGURE 5, to form overhanging eaves for the building. From the two ends of element 18 the panel extends upwardly to an apex of 58 and is conveniently bounded by a piece of 2" x 3" wood designated as 19 along eachcdge with the 2" faces of the pieces against the panel. A flashing or rain apron 20 extends along one side of each panel 12. Panel 12, like panels 10 and 11, is provided along each edge with connecting elements 15.

The arrangement of the elements 15 on the panels is in a manner of dynamic symmetry so that the elements 15 will not fail to be properly located to fall adjacent the complementary element 15 of an adjacent panel.

Regardless of the size of the building to be erected, the sides 13, 16 and 18 of the set of panels from which the building is to be erected must be equal. The placing of the element 15 on panels 10, 11 and 12 are such that, in the set, any panel 10 will be connectable along its side to any panel 11, and any panel 11 will also be connectable along its upper edge to the edge 18 of any panel 12. And, any panel 12 will, of course, be connectable to any adjacent panel 12.

It will be noted that the elements 13 are slightly thinner than the elements 16 because it is desired to have the flashing 17 lie outwardly of the panels 10. No interference, however, will occur if the elements 13 are of the same dimension and positioned exactly as the elements 16 are positioned. The reason for having the 2" x 3" element 18 lie edgewise whereas the 2" x 3" element 16 lies fiatwise is illustrated in FIGURES 8, 9, l and 11, which show sections of an assembled house of triangular, square, pentagonal, and hexagonal, respectively, taken at the juncture of the roof panel 12 and the side panel 11. It is clear from FIGURES and 11 that in these exemplifications the element 18 could be equally well placed flatwise against the panel 12, where pentagonal or hexagonal buildings only are contemplated.

FIGURE shows a schematic layout for a triangular building according to the present invention. In this case it is clear that the triangular floor 21 will have three panels 10 connected to it, one along each side of the equilateral triangle 21. A side panel 11 will be mounted and secured to each side panel 10 so that the upper edge of the side panels 11 form an equilateral triangle which is rotated 60 with respect to floor triangle 21. Each upper edge of a side panel 11 will be secured to a roof panel 12 and each roof panel 12 will be secured to two adjacent roof panels to form a triangular pyramidal roof.

In case of a square floored building, there will be four side panels 10, four side panels 11, and four roof panels 12. The base or floor of such a square building will be square having sides equal to side 13 of the side panels 10. The platform for a square building may be a single piece or may be made of two or more triangular pieces. A square building is shown in FIGURE 1.

Where a hexagonal building is desired, which is shown in FIGURE 2, six panels 10, six panels 11 and six panels 12 will be required. Clearly, one of the panels 10 in any building should include a door, or entry, and, if desired, any of the panels 11 may be provided with windows.

It will be noted that the device of the present invention will be of use even without a platform or floor, in which case, panels 10 and 11 are merely secured together edge to edge, stood up in generally vertical position, and the roof panels 12 secured to the top edges of panels 11 and to each other.

For the triangular or square building a triangular or a square base may be prefabricated as a unit or may be formed of a plurality of subassemblies and appropriate securing elements 15 mounted along the upper outer edge of the base. FIGURE 3 shows a suggested manner of forming a floor platform for a pentagonal building which is broken down into five triangular elements and one trapezoidal element which would be comparatively light, of small dimension, easily stowed, packed, and carried. In this case, two joist elements 22 are provided to carry the fioor load to appropriate corners of the pentagonal floor. Since the method of supporting the joist elements in FIGURE 3 is the same as for the joist element in FIG- 4 URE 4, the support will be described in connection with FIGURE 4, taken with FIGURES 16, 17, 18, 19 and 20.

From FIGURE 20 we see that a two-story building may be erected using the elements of the present invention. The side wall panels 10 and 11 that form the walls of the second story of the building are exactly like panels 10 and 11 which are used for the lower floor of the building. Referring to FIGURES l6 and 17, it will be seen that there may be a joist element 22 which is also seen in FIGURE 4 extending directly across the center of the hexagonal building.

In a single story building it is only necessary to support the ends of joist element 22 and to support the other four corners of the hexagonal building on piers of some sort. In making the two-storied structure of FIGURE 20, however, it is necessary to support the floor for the second story from the periphery of the upper edge of the side walls of the lower story. This is done by providing fastening elements 15, similar to the fastening elements 15 on the other panels, on the marginal edges of each floor panel 23 of a hexagonal building. As seen in FIGURE 16, these securing elements 15 at the bottom edge of the marginal strength elements 24 of a floor panel will be positioned so that they may readily be connected to the element 15 on the upper peripheral edges of panels 11 of the lower fioor of the building. A special joist hanger 25 is provided which has loops 26 at each end arranged so as to lie in alignment with and immediately adjacent the connecting element 15 as seen in FIGURE 18. Preferably a wooden block seen in FIGURES l6 and 17 is mounted on the element 25 to rigidity the device and to distribute the load more effectively, and providing connections between hanger 25 and loops 26 long enough to be twisted if necessary for use in other buildings.

A common pin 27a connects the elements 15 on panel 11, element 15 on peripheral strength element 24, and the joist hanger 25. The difference in angle required between loops 26 in a pentagonal building from that in the hexagonal building would be attained by reforming the hanger as by a hammer.

In erecting the building, after the side panels 10 and 11 of the lower floor have been erected, the joist 22 may be put in position extending across the building and resting on the joist hangers 25 at each end. The joist may be spiked or bolted to the joist hangers. The floor panels 23 and 23' on each side of the joist may then be bolted to the joist after they have been secured by their elements 15 to the top edges of the lower panels 11 and similarly fioor panels 23" will be bolted to the adjacent panels 23 and 23', respectively, on each side of the building.

At the top edge of each of the panels 23, 23, 23, there are elements 15 to which the panels 10 of the upper floor of the building are to be secured and are to be erected with panels 11 in the same manner that the lower wall panels 10 and 11 were assembled on the lower floor platform which was erected on piers. R-oof panels 12 are then assembled to roof over the upper floor of the building.

There are minor differences in the exact proportioning and shape of the panels 23, 23' and 23", which are immediately apparent upon inspection of FIGURES 16 and 17, taken with FIGURE 4, due to the interposition of the joist 22 between the two halves of the floor platform. Where only single story buildings are contemplated, a central pier could be used with identical equilateral triangular floor panels.

FIGURE 21 shows diagrammatically a single floor building made according to the present invention which may be moved by a crane at a construction site or since, when empty, a building using 8 foot equilaterial triangular panels will weigh about 2500 pounds, such a building may be moved by helicopter if necessary. In this case the central element 30 is a steel pipe, or the like, that ties the floor to the roof.

FIGURES 12, 13, and 14 show plan, elevation and section, respectively, of securing elements 15. Each element 15 has a leaf portion 15a, and an eye or gudgeon 15b to receive a pintle 27. The axis of the pintle when in place is at the corner of the building element on which the securing means 15 is mounted in order that, as assembled in buildings of differing numbers of sides the space between the panels secured =by the elements 15 will always be minimal. This is illustrated in FIGURES 8, 9, and 11, where, in assembling roof panels 12 to side wall panels 11 for each of the buildings suggested, the spacing between elements 16 and 18 is very small as these elements are held in corner-toc-orner relationship.

In extremely cold climates the panels may include insulating material and the joints between adjacent panels may be packed. There will always be a wedge-shaped space between adjacent panels, except for the joint of FIGURE 8 between panels 11 and 12, which is tight to the degree that it illustrates the desirability, if three-sided buildings are to be erected, of providing relief between elements 16 and 18 to avoid straining the panels. The flashing or rain apron over the joints between adjacent panels will help retain any packing provided. It is noted that a flashing or rain apron may be used in lieu of or in addition to the extension of the panel below element 18 in FIGURE 5 to carry water over the joint between panels 11 and 12 and over the top ends of flashing 17.

I therefore claim:
