6 Claims. (Cl. 108-1) My invention relates to a framework for enclosing space, and to building construction members for use in such a framework and for other uses.

Summary Frameworks used in buildings, and for roofs and shelters of all kinds, commonly are constructed of steel, aluminum, wood and the like, and the design of such frameworks is based upon long familiar principles in which relatively heavy compression members are employed in columns, beams and girders. Because of columnar, or compression, loading of such members, they must in general be heavy and stilf to resist buckling under compression. As a result, the ratio of weight to strength is high. In times past, efforts to gain a more favorable weight-strength ratio have brought about the development of the I-beam and the lattice girder; and in more recent times the continuance of such efforts has led to the development of light metals and their strong alloys for use in place of steel where cost does not preclude availing of such lighter weight but more expensive substitutes. Apparently those concerned with the development of frameworks for building construction have not perceived any practicable means to eliminate the use of materials and columnar forms which have high com pressive strength. However, I have discovered how to make a building construction member which possesses design characteristics such that the compressive strength of component portions thereof is of relatively small, and perhaps almost negligible, concern. It has been a primary object of my invention to achieve such design characteristics in a general purpose building construction member.

I have found further that, by following the design features disclosed herein, it becomes thoroughly practicable to construct building frames of paperboard and I the like. So, in popular phraseology, one might say that I have discovered how to make cardboard building members and framesmembers possessing such surprising strength characteristics as to permit the use of cardboard in lieu of Wood, aluminum, steel or other materials which, according to normal concepts of strength of materials, are not at all to be associated with such flimsy stuff as cardboard.

According to my invention there is provided a building construction member in the form of a polygonal frame, such as a triangle, having hollow sides preferably triangular in cross-section and centrally reinforced. This member is formed from a single flat piece of paperboard or the like comprising a series of elongated panels arranged .end' to end with transverse fold lines between the panels,

'and lateral extensions adjoining the panels along longitudinal'fold lines and including fold lines spaced from and substantially parallel to the longitudinal fold lines; The lateral extensions fold about both the longitudinal and parallel fold lines to form a hollow box-like structure 'which in turn folds about the transverse fold lines 2,881,717 Patented Apr. 14, 1959 ice between the panels to bring the outer ends of the structure together to form the triangular, or other polygonal, frame.

The ends of the lateral extensions are formed with flaps infolding along diagonal lines to form abutting mitered surfaces at the ends of the hollow sides of the polygonal frame. An important feature of my construction resides in gauging the angle of these diagonal fold lines to the number of sides of the polygon to crowd the folded lateral extensions within the perimeter formed by the interconnected panels, and set up the mitered joints of the polygon under a degree of pressure for increasing the unitary strength of the frame as set up for use. The elongated panels forming the perimeter of the frame may thus be placed under a degree of tension, tending toward a uniform distribution of stresses throughout the frame, with utilization to a marked extent of the tensile strength of the paperboard in what may be regarded as a skinstressed frame member.

For further maximum realization of tensile properties as well as the compressive strength of the box-form frame portions, at least the outer surfaces of the polygonal frame are coated with a thin plastic film of high tensile strength, such as a vinyl resin which can be brushed, sprayed or otherwise applied to the completed frame members, or which can be applied to one or both sides of the paperboard from which the blanks for the frame members are cut. Extrusion coating can be used to apply the plastic reinforcement to the paperboard sheets, or the paperboard can be impregnated with the plastic. I have found, for example, that a triangular frame member formed in accordance with my invention, when brush painted with a thin film of vinyl plastic acquires astonishing strength characteristics. Thus, such a frame member having nearly equal sides averaging about 19.4 inches in length, the cross-section of the sides being of hollow triangular form with a base width of about 5 inches, and an altitude of about 1.5 inches, is of such strength that when placed with one side of the triangle on the floor it is possible for a 200 pound man to step up on the opposite point of the triangle and place his full weight on it without the slightest visible evidence of distortion or buckling of any of the sides of the frame member. The paperboard used may consist of the ordinary kraft board used in standard forms of shipping containers, and known as corrugated fibreboard. In the example just given; I employed a double-faced sheet in which the smooth outer sheets, known in the paperboard box business as liners consisted of a 38 lb. kraft board (38 lbs. per 1000 square feet) made from sulphate virgin Y pulp and glued to a 26 lb. kraft corrugated member having approximately 55 flutes per lineal foot (known in the trade as a type B flute), the board having a thickness of about 0.100 point).

The many desirable properties of my new building construction members are realized most fully when these members are assembled in such a manner as'to form a building framework constructed in accordance with my prior Patent No. 2,682,235, issued June 29, 1954. For this purpose the building members described herein may be made as frames having three, four, five or six sides corresponding to the triangles, diamonds, pentagons and hexagons described in said patent. Alternatively, the diamonds may be made from two triangular frames se-' cured together back to back, and the pentagons and hexagons can be made, respectively, from five and six triangular frames secured together in rosette fashion. 'In' such constructions, each component member reinforces and lends strength to the structure as a whole, and the tensile strength of the extremely thin paperboard and plastic sections is utilized to tremendous advantage, and

to an extent not realized in'the conventional forms of structures heretofore known-or used.

These and other features and advantages of my invention will appear more fully in the detailed description which follows.

'Fig.'l8 is a face view of a building construction member having four sides instead'of three,"formed from a blank similar to that shown in Fig. 1 or that shown in Fig. 15.

Referring to Fig. 1, my invention comprises, in its general arrangement, a building construction member formed essentially from a singlefiat piece of paperboard or the like, comprising a series of

elongated panels

20 arranged end to end,

transverse fold lines

21 between the meetingends of said panels, and lateral extensions22 adjoining the elongated panels along

longitudinal fold lines

23 and including

fold lines

24 spaced from and substantially parallel to the

fold lines

23, the lateral extensions folding about the longitudinal and parallel fold lines (Figs. 3, 4 and 5) to form a hollow box-likestructure 25 (Fig. '7) which in-turn'folds about the

transverse fold lines

21 to bring the outerends thereof together-to form a polygonal frame 26 (Fig. 6) with hollow sides. The ends of the lateral extensions preferably are formed with'flaps 27 and 28 infolding along

diagonal fold lines

29 and 30 to form abutting

mitered surfaces

31 at the ends of the hollow sides of thetriangular, or other polygonal, frame. As ,shown,'these flaps .areformed in pairs wit the espective. m mbers of .each p o ate a onrn s t si c ofth a ore aid pa al el ldine .2

:Th ng e o t di gona o l es 2 a 3 w l depend upon the number of sides there are to be in the pnly nal m and, m sp cifi a ly, p the ve tex angle, or angles, between each two sides, and the angle of these diagonal fold lines is additionally gauged (after taking account of the number of sides, i.e. the vertex angles) to crowd the folded

lateral extensions

22 within the

perimeter panels

20, 20, etc. of the polygon and set up the mitered joints of the polygon under a degree of pressure. This has the result of locking the several components of the frame together for maximum strength as a unit, and tends to distribute stresses encountered by any one part of the frame to the other parts thereof. This may be due in part at least to the fact that the

perimeter panels

20, 20, etc. are placed under a degree of ten sion. Whatever the cause, I have .found that building construction members made as I have described, possess astonishing strength, particularly when they are assembled in a generally spherical form in such a manner that the sides of the polygons lie substantially in planes whose intersections with the spherical surface define great circles of that surface. Means are provided for securing ;together the outer ends of the hollow box-like structure. In the preferred construction shown, a pair of endflaps (Fig. l) 41 are formed as extensions of one of the

perimeter panels

20 to be tucked into openings 42 (Fig. 5, and cf. also Fig. 6). Adhesive tapes or other securing means (not shown) may also be applied around the meeting ends of the structure.

my pr ed tr on add tio a v a st 1 partedbyproviding the

lateral extensions

22 at both sides of the

elongated panels

20. These extensions are folded first diagonally inwardlyas shown at 32 in Fig. 7, and then outwardly to form a

central reinforcement

33, 33 comprised by the outwardly folded portions of the lateral extensions. These outwardly folded portions hear at their ends against the inside of the elongated panels Y20 and divide the box-like structure into two triangular com.- partments. If desired, a locking pin or pins 43 may be provided, extending through suitable openings formed in the

portions

32 and 33 of the lateral extensions.

The manner in which the

lateral extensions

22 and their infolding flaps 27, 28 are folded to form the hollow box-like structure is further revealed in Figs. 2, 3,..4 .and 5. In the first three of these views, the .arrows denote the directions of folding.

Flaps

27 go inside of, and reinforce, flaps 28 to form the abutting mitered

surfaces

31 to which reference has been made.

Figs. 13 and 14 show how a

panel

34 may be used to close the center of the polygonal frame, the outer portions of this panel being received between the outwardly folded

portions

33, 33 of the

lateral extensions

22. By inserting

panel

34 during the operation of folding the sides of the hollow box-like structure about the

transverse fold lines

21, the panel is permanently locked in place. This panel further serves to reinforce the construction, and it may be made of any desired material such as paperboard, beaverboard, plastic, aluminum foil, etc., and may be opaque, translucent, or transparent in accordance with the functions to be served, i.e. whether for letting in, or obstructing the passage of, light, con ducting, or insulating against the passage of, heat, etc.

The modified construction illustrated in Figs. 15, 16 and 17 is substantially identical with the preferred form described above, with the exception that the 1l=ral.;

extensions

22 are present on only one side of the

elongated panels

20,-and are replaced by

flaps

44 which ,are secured to

extensions

22 in the overlapping relation shown in Fig.17, as by means of a plastic, or other, adhesive, or by means of metal staples, or both, or otherwise, as desired.

Figsgoand

16 assembled to-forma hexagon accordingto one of th b-compon nts o a bu din c ruc io fr m work made in accordance with my prior Patent No. 2,682,235, aforesaid. Other arrangements are possible so asqto forrrnfor example, diamonds madefrom t w o triangular frames secured together back to back, or pentagons made from five triangular frames secured together in rosette fashion similar to Fig. 8 (compare Figs. 2 and 5 of my patent aforesaid, with reference to the pentagon at the zenith Z and at each junction of the vertexes of the great circle triangles of the spherical icosahedron).

Fig. 18 shows another of the many possible forms of polyhedral building construction members which can be formed in either of the manners described, i.e. by utilizing blanks of the general form of either Fig. 1 or Fig. 15. In this case one

additional perimeter panel

20 is added to the blank and the lengths of the respective panels are adjusted to the desired measurements. It may be observed here that my building construction members have been found suitable not only for use as components of building frames in which the members form a permanent part of the structure, but also may be used as temporary supporting members in constructing openings such as doors, windows, etc., in erecting buildings of conventional types.

In assembling my improved construction members, various arrangements are possible for holding the members together; I have employed wooden pins, both alone and in conjunction with metal clips. Also, I have found it efficacious to bind triangular frames together in diamond, pentagon, and hexagon assemblies, by passing glass fibre tapes around the complete periphery of the diamond, pentagon or hexagon. Such glass fibre tape is available as a Scotch tape and is exceedingly strong in tensoin, thus contributing importantly to the over-all strength of the completed framework, particularly when it is constructed in accordance with my prior Patent No. 2,682,235, aforesaid. In such constructions the several components so complement one another in the particular pattern of the finished assembly as to enable it to withstand high stresses, and the framework itself acts almost as a membrane in absorbing and distributing loads.

Another feature of my present invention resides in the provision of means for predetermining the correct angular relationship between each building construction member and its neighbors. This feature will be described with reference to Figs. 9 to 12 inclusive. Fig. 9 is an enlarged detail cross-sectional view taken as indicated at 9-9 in Fig. 8 and shows two

triangular frame members

26 back to back, or substantially so. The construction of these frame members is the same as has been described with reference to Figs. 1 to 7 inclusive. The

elongated panels

20 and

lateral extensions

22 of one of the

frames

26 are provided with perforations to receive alignment pins extending through similar perforations in the other

polygonal frame

26 of like construction. These perforations are slightly out of alignment with the planes of the respective frames to predetermine the angular relationship of the two frames. More than one set of such perforations may be provided so that by selecting a particular set, one particular angular disposition of the adjacent frames is obtained, whereas by selecting a different set of perforations, another angular disposition of the adjacent frames is obtained. Thus, by following a plan or set of specifications indicating the correct placement of the pins, structures of predetermined form are obtained without requiring knowledge or skill on the part of the workmen. I prefer to form the perforations by making out lines in the paperboard without punching out the centers. Then, by punching out only those openings through which pins are to be passed during erection of the structure, the correct relation of the several components will be obtained without even the need to examine the specifications on the job.

Referring further to Figs. 9 to 12 inclusive, it will be observed that I have provided a building construction member of the character described, in which the

elongated panels

20 and

lateral extensions

22 are provided with a number of perforations, the alignment of which,

when the member is set up for use, being as follows: one

perforation

37 in a

panel

20 opposite a

perforation

38 in an extension of such panel comprising one pair of perforations to receive an

alignment pin

39, and another

perforation

35 in said

panel

20 opposite another

perforation

36 in said extension of such panel comprising a second pair of perforations alternatively to receive

alignment pin

39, the pin axis of said one pair of perforations being at a slight angle to the pin axis of said second pair of perforations, and the pin axis of at least one of said two pairs being at a slight angle to the plane of the polygonal frame. In the example illustrated in Figs. 9 and 10, one of the two pairs of perforations, viz.

perforations

35, 36 is blind, while the other pair, viz.

perforations

37, 38 is completely punched out selectively to predetermine the angular relationship between said frame and another frame of like construction. In the example illustrated in Figs. 11 and 12,

perforations

35 and 36 have been completely punched out while

perforations

37 and 38 are blind, to predetermine another angular relationship between the two frames. Thus, by placing the

pins

39 through the punched out

perforations

37, 38 of Figs. 9 and 10, the condition illustrated in Fig. 9 is obtained, whereas by placing the

pin

39 in the punched out

perforations

35 and 36 of Figs. 11 and 12, the condition illustrated in Fig. 11 is obtained. In the first instance the angularity between the planes of the two frames is slight whereas in Fig. 11 the angularity is somewhat greater. The difference in the two angularities has been shown with considerable exaggeration in these views in order to reveal the principle of operation more clearly. It will be understood that additional apertures may be provided in order to afford a larger range of angular relationships to choose from. The gore between the backs of the two frames may, if desired, be filled with a triangular paperboard element or other filler piece. Also, a metal band or clip may be passed around the meeting edges or corners of the frames to be held in place by the alignment piece, or otherwise, as may be desired.

A second set of

perforations

35', 36, and 37', 38' may be employed to receive, selectively, an

additional pin

40, and it may be understood that as many additional sets of such perforations can be used as will be best suited for a particular utilization of my invention.

In summarizing my invention at the beginning of this specification, I have referred to the coating of the frames, or the paperboard from which they are formed, with a thin plastic film, such as a vinyl resin, which can be brushed, sprayed, or otherwise applied. I have found that a surprising degree of strength can be imparted to the paperboard structure by the use of vinyl plastic films which are on the order of A inch to ,6 inch in thickness, although other thicknesses may be employed as desired, and the frames can be used without any coating whatsoever, particularly if an impregnated or waterproof paperboard is employed.

The terms and expressions which I have employed are used in a descriptive and not a limiting sense, and I have no intention of excluding such equivalents of the invention described, or of portions thereof, as fall within the purview of the claims.
