Fried Dec. 27, 1955, ser. No. 555,565 z claims. (orzs--15'4il This invention relates to shell type concrete building construction and it refers more particularly to the method by which individualunits may be produced as well as to .the method of combining the unitsin erecting a building.

The principal object of the invention is to improve upon known methods of erecting shell type buildings by first creating a` new basic unit composed of a frame- Work of relatively slidable and intercrossing rods and a` covering consisting of rows of correlated overlapping sections of expansible llexible material so connected to the frame-Work as to permit the sections to move independently and collectively, thus to assume the curvature oli-ther rods along two transverse aXesas the rods are bent into the shape in which they are to remain in association with like assemblies in a completedbuilding.

Another object of the invention is to provide a shell type building composed of a multiplicity of interconnected flexible units which areA Prefabricated `011 a flat plane where they are arcuated along their minor axes and `hoisted into the relative positions they will assume as the frame-work of the completed building, during which `each unit is i arcuatedalong its major axis, if the building is tobe dome-shaped, tubular or of other de-` signs involving compound' curves. Subsequent to the erection of the building units individually or `collectively to completethe building frame-work, a plastic;` or cementitios material is shot onto or otherwise applied to the fabric covering which hardens and perinanently integrates the assembly into .a structure capable of withstanding all normal compressive stresses without'- need for the supporting and reinforcing mediums common `to conventional buildings.

"vS'till another"object ofthe invent-ion is to provide a` structural unit as specified, whose initial configuration predetermines the ultimate shape of the building of which" it forms apart, whether the building is to be a warehouse, airplane hangar, shelter or even a spheroid, the latter 4being composed of `two` dome-like or hemisphericalV structures anticipated herein.

Other objectswill appearas vthe description proceeds when considered` witlrthe annexed drawing" wherein:

" Figure9A is aplan view of an assembly of the' structural units shown inFigure 8 in the initial stage preparatory to springing into the position shown in Figure 1 0, and i `Figure l0 is a side elevational view of the supporting `fabricationof a dome shaped structure for-med by the assembled units of Figure 9, preparatory to receiving the cementitiouscoating. i

Continuing with a Vmore detailed description of the drawing, reference'is made primarily to Figures l to 5l wherein reference numeral 10 denotes generally what,

isherein referred/to as a building unit or a structural unit, of whiclifseveral are employed in jiuxtaposed and` interconnected relationship to form the supporting fabricationof a building whose shape is determined by the configuration of theV individual unit 10, as will become apparentV as the description proceeds.

Each `structural unit 10 is composed primarily of a pluralityuof` longitudinally parallel rods 11 and a plu-n rawlityfof,r intercrossing' transverse rods 12. Overlying the assembly of rods 11 and 12 is atfabric covering," generally indicated by reference numeral 13 but which/ isf` `actually in overlapping, slidab'le sections, each identied by, reference numeral 14.

` 'I`he-rodsf11` and 12 are placed on a flat ysurface in the relationship shown in Figure 1 and the sections 14, of the` fabric covering 13 are attached to the rods at the points "of intersection by means such as the clips 15, oneofwhich is shown on an enlarged scale in Figure 5.` It'will .become evident present-ly that the rods 11 must be-slidable in relation to the fabric cover sectionsi lflghencethe clip 15 is formed with a loop' 16 (Fig. 5 through which these rods 11 slide longitudinally. Since the fabrics 13` is eXpendable, the rods 12 extending across the short" axis of thefabric covering can be and are aigiedto tlfleclipsv 15, asY by Welding and the clips 15 '1 are sezcuredwto` the` cover sections 14 by means of the` legs 17, Figure 5,'Whichcxtend through and are bent upon the fabric.

` The described`-elements of `the structural unit 10 are` assembled` over aiv uplurality of transverse parallel base rodsflS. "'Theends ofthe `rods 18 along one side of the assembled .unit y10;a're' 4 secured to the adjacent outermost'` longitudinal rod 11 by any suitable means auch as having thelends (Fig, 2i)e`belnt Varound said outermost rod, 1K1, Theoppositeedge ofothe structural unit 10` need not bei` connected toA the transverse base rods 18 since the covering 13 is to be warped or arcuated, as shown in` Figure; 2` along the. longitudinal -axis of the unit by eiierting aiforce laterally againstthe edge of the unit itetheanchoredpoints 19.` of the base rods 13.l d-one by anysuit'ablehtol but preferably by ratchet jacks, not shown,` which are attached to the base rods ISanda-dvanced thereon toward their anchored ends 19, meanwhile engaging `the free edge of the cover 13,'.

obtains," free `edge of the unit 10 is suitably tied `to thetransvierse baserods 18` or their opposite ends l20 (Fig, 3) ,maybe bentfupwardly against the sides of the nownarcuated unit to` prevent recoil.

It isto. be observed in the several `figures that the` sections 14 `ofthe",fabric cover 13 have theiryadjacent edges 21 overlapped This is `done in `order that the sections 14 may individually shift `their positions to contraensate for the curvature imposed in the longitudinal -rodsl Patented Aug. 9, 1960,

11 when the unit 10 isbowed along its transverse or minor axis, as shown in Figure 3. y

There are many ways in which the units 10 can be brought into the shape shown in Figure 3 and since this wouldbe obvious to those skilled in the fart, it is considered adequate to explain that the most suitable manner of springing the unit would be by means of a craneyhoist with cables connected at strategically shaped points along the length of the unit 10, depending upon the particular curvature of the arch, that is, whether true centered, three centered, oantilevered or other design. This would apply also to the dome structure shown in Figures 8 and l0, which will be presently described. t

In constructing a tunneltype structure, such as suggested in Figure 4, whether it be a building, culvert, bridge or other fabrication, the units 10, when preformed in the manner explained or in the shape illustrated in Figure 2, they are progressively joined together by suitable ties and the fabric covering 13 is shot with a cementitious outer covering which, when it hardens, forms a rigid shell which reinforces the supporting fabrication against all normal stresses to which any conventional building is tion of the units, which closes Vasthe units assume their subjected, the greatest of which is compression. t No other support is needed to make the structure self-sustaining because of the continuous wall span created by the arcuated units. Y

It is evident also that the same units 10, constructed and formed in the manner explained, may be disposed on la horizontal plane instead of the vertical plane shown in Figure 3 and joined end to end to form a circle. The circular structures thus fabricated may then be superimposed one upon the other to form a structure in the nature of a silo or grain elevator. Moreover, in any such construction, the units 10 may be arcuated along the major -axes opposite to that shown in Figure 3 so that when the units are assembled in a building, the curve on the transverse axes of the units will be concave instead of convex on the exterior of the building.' In Figures 6 to l0, the same method is used in forming the structural units to produce a supporting fabrication in a dome-like building identified broadly in Figure 10 by reference numeral 30. The only difference between the structural units of the modification shown in these figures and those just described being in the configuration of the unit which, in Figures 8 to l0, are generally indicated by reference numeral 31.

The units 31 are identical to each other and each consists of longitudinally coextensive rods 32, converging towards one end of the unit. Intercrossing the rods 32 are transverse rods 33 and to the rods 33 is welded a series of tubular retainers 34 through which the longitudinal rods 32 slide The expandable fabric covering, generally indicated by reference numeral 35 is composed of progressively tapered sections 36 whose adjacent transverse edges 37 and adjacent longitudinal edges 38 are overlapped (Figures 8 and 9).

In Figure 9 the units 31 areshown assembled on a flat plane such las concrete slab (not shown). The apices of the triangular units 31 meet at the center. As each individual unit 31 is formed, it is sprung into the arcuate form shown in Figure 6 by means of the transverse, longitudinally spaced base rods 39, one end 40 being secured to the outermost longitudinal rod 34 while pressure is applied inwardly all along the the Vopposite edge of the fabric covering 35. As each unit `is thus arcuated along its major axis, its edge is tied in any suitable manner to the adjacent edge of the companion unit.

, After all of theunits have been assembled in the manner explained, a crane hoist is employed to raise the assembled units to the positions shown in Figure 10. A cable may be connected to. the center of the assembly and a series of cables connected at annularly spaced points to the units between their inner and outer ends.' By ,controlling the pull 'on the'cables, the dome-shaped supporting ,fabrication shown-iserected. Y

final position in the structure, after which Vthe adjacent edges of the units between which the gap 42/was formed, are joined together.'

When the assembly ofl units has been sprung to the desired shape, the fabric covering35 is shot with a cementil tious composition which, when dry, provides a rigid weathertight shell about the supporting fabrication;

By constructing two identical hemispherical bodies resembling that in Figure l0 and joining these bodiestogether to form aA spheroidal body, a tank may be thus produced which may be supported on a tower or embedded in the earth to contain liquids or solids for storage.

It is evident from the foregoing that the rod retaining members shown in Figures 6 and 7 may be interchangeably used with the structures shown in Figures 1 to 5 and 8 to 10. f

Manifestly, the steps of the method herein dened are subject to certain changes and modications and these are considered to be within the spirit and intent of the invention as long as they fall Awithin the scope and meaning of the appended claims.

What is claimed is:

l. A method of building structures which comprises arranging a supporting fabrication of inter-crossing and relatively slidable exible elements on a flat plane,.attaching expandable fabric covering material to the supporting fabrication, in rows of overlapping, individually movable sections, to form one of a plurality of structural units, exerting a force laterally against one edge providing -a supporting fabrication of inter-crossingand relatively slidable rods, attachingV a row of overlappingV individually movable sections of cover fabric to the supporting fabrication to form a structural unit, restraining the unit along one edge while exerting a force along the opposite edge of the unit to produce a curve therein along one axis, exerting a force on the unit perpendicular to said one axis to produce a curve in theunit along another axis transverse to said one axis, and finally applying cementitious material to the cover fabric.
