STRUCTURAL FRAMEWORK;

Application filed October 28, 1927, Serial No. 229,462, and in Belgium Kovember 3, 1926.

My invention pertains to building constructions, and more particularly to supporting frame work therefor.

It is one object of my invention to provide a S supporting frame for building construction that will permit of rapidity of erection with great strength and at a reduced cost over previous methods of construction.

It is a further object of my invention to provide a system of supporting frame work of sullicient lateral strength that no intermediate supports will benecessary even for great spansfar in excess of that which is possible by present known methods of frame work construct-ion.

It is a still further object of my invention to provide a system of frame work construction that will permit of the building of varying sized structures, there being but four different sized pieces of frame regardless of the size of the structure.

Briefly, the framing comprises a series of rectangles formed by overlapping long pieces, shorter joint covering pieces, spacing members forming sides of the rectangles and cross braces. The longer pieces abut end to end and overlap so that the bolts that hold the assembly together pass through the respective ends of the joint and the center of an ad acent piece. For additional strength, the open joint may be covered by a shorter joint-covering piece held by the same bolts. bpaclng members may be secured in any well knownmanncr between the above-described assemblies, but strength will be added to the structure it the spacing members abut against the ends oi the cover joint pieces. However, with this arrangement, every other rectangle will be without a means for bracing the structure against lateral stresses. Accordingly, in

, every other rectangle placed an ordinary crossbrace,tl1e members extending diagonally from one corner to the other. As a further means for strengthening the structure, long tie bolts maybe provided extending from one of the assemblies to the other, and preferably passing through those rectangles in which the cross braces are located.

Other objects of my invention will be un derstood from the accompanying specification and drawings, wherein,

Figure 1 is a front sectional elevation of my invention as applied to a roof, such as an aviation hangar, parts being broken away to :lacilitate illustration, and

Figure 2 is a plan view thereof.

, Referring to the drawings, the framework is constituted by four elements cut to respective size to form arectangle and the lar size of structure is accomplished y mere duplication of the rectangle. The size of the rectangles and therefore the size of the four pieces is n'edetermiued in accordance with the stresses and strainswhich the particular structure to withstand, it being the intent of this invention toprovide a structure wl1erein no bracing members areprovided at an angle thereto. i a

One of the rectangles is formed by walls a, b, c and 0!. Walls 6 and (I extend beyond the walls a and 0, as shown at e, f, g and h. The portions 6 and g abut against pieces 0' and g and the ends f and h abut againstthe pieces f and h respectively. The pieces 6, f, g and h are exactly similar in size and length to the pieces I) and (1. Thus, the next adjacent rectangle to that formed by the walls a, b, e and (Z is formed by the portions 0, e, g, 9, re-

spectively and a sidewall Z similar to the pieces a and c. a M

Overlapping the joint between the pieces 6 and e is a second strip d similar in size and length to the piece d. Thus the joint 6, e oc} ours in the center of thepiece This ar rangement is true of eachpf the joints. Ac cordingly, when bolts or other securingmeans in join together the pieces (Z and d great strength is obtained by this overlapping of joints. This same arrangement occurs between joint g and y where strip 7f overlaps this joint. a l

One of the joints is always left exposed in diagonally opposite rectangles and, these joints are covered by short pieces or strips an which are of a dillerent length than tliepieees a and I. but are adapted to abut thereagainst Eart cuso as to give increased rigidityagainst lateral stressesto this particular rectangle.

In the rectangles which are not braced by the strips m are cross braces formed by strips 2? and j which extend diagonallyfrom thecorner formed by the pieces a, (Z to the corner formed by the pieces I), 0. Thus, every rec tangle is braced against lateral stresses, and all joints are well protected. j

The cross braces a l-and j and the spacing strips (1, c and Z are secured in place by any well known means.

As a further means of strengthening the structure, tie bolts it may be used, between the horizontal extending assemblies of pieces 03 and d 6 and b respectively. The tie bolts preferably extend through the rectangles containing the cross braces 2', and thus allparts oi the assembly get full benefit of the result of using the tie bolts, since they pass through the pieces 5, 5 (Z, (Z and the respective joint covering pieces m. It has been found sulficient to merely add two tie belts in each rectangle containing a cross brace.

It is immaterial whether the pieces out of which thisstructure is formedare made.

of metal or of wood, and whether the securing members are belts or rivets. The same rigidity of construction is obtained.

If the structure is to be arched such as the roof of an aviation hangar would be, the ends of the pieces (Z and 7) would be cut at an angle which would be a radius of the partieulararc to be used in the construction so that the ends of the pieces would abut throughout their lengths and not at ust one point tlvreon. If desired, the ends a and c of each piece d or b may be tapered slightly as indicated in Figure 1. Also, if desired, the upper edge of the piece (Z and Z) may be cut on the same curve as the are of the support, as indicated at 0, but with a plurality of relatively small pieces, this is not essential.

Modifications may be made in the arran ment and location of parts within the spirit and scope of my invention, and such modi fications areintended to be covered by the appended claims.

I claim:

1. Structural frame work comprising a plurality of assembled strips extending in one direction, each strip comprising a pinrality 0t abutting and overlapping pieces so arranged that the joint between abutting ends occurs substantially at the center of the overlapping piece, additional pieces for covering the exposed joints between abutting ends, means extending through said pieces tor securing the same together, and spacing members secured between the a sembled strips and adapted to abut against the endsot the oint covering iieces.

Structural frame work comprising a plurality of assembled strips extending in one direction, each strip comprising a plurality of abutting and overlapping pieces so arranged that the joint between abutting ends occurs substantially at the center of the overlapping piece, spacing members secured between the assembled strips so as to form a plurality of rectangular caissons and X-- each strip comprising a plurality'of abutting and overlapping pieces so arranged that the joint between abutting ends occurs substan tially at the center of the overlapping piece, additional pieces for covering the exposed joints between abutting ends, means extend ing through said pieces for securing the same together, and spacing members secured between the assembled strips and adapted to abut against the ends of the joint covering pieces so as to form a plurality of rectangular caissons and cross braces secured in said rectangles on the opposite side of the spac- :ing member from that abutting against the joint covering pieces.
