RooF l Filed Feb. .19, 1958 2 Sheets-Sheet 2 Patented July 16, 1940` UNITED STATES Leon Beschkinc, Paris, France, assignor to Entreprise Rouzaud et fils, Paris, France, a

corporation of France Application February 19, 1938, Serial No. 181,533 In France February 26, 1937 7 Claims.` (Cl. 10S-23) `My invention relates to improvements in those known roofs constituted by curved sheet iron or metal covers arranged adjacent or apart one with reference to the other so as to form the 6 covering means proper.

My invention consists chiefly in arranging v arches in the longitudinal direction of the covers, said arches being constituted for instance by box girders for which the covers form tie-rods.

Preferably the covers are hung, at intermediary points of their lengths, to the arches through suitable ropes, chains or the like.

Although I may provide for each cover an arch for which said cover acts as a tie rod, it is prefer- 15 able to provide one arch for several covers. The arches are then interconnected at their ends through curves such as parabolas, for distributing the stresses and these curves are connected with the ends of the covers through suitable girders.

Similarly for the transverse suspension, two

adjacent arches are connected through curves such as parabolas for instance, arranged in transverse vertical planes and to which the suspension means are connected. 25 The arrangement according to my invention allows the execution of covering means of considerable span while of reduced weight and the arches of which exert no thrust on the walls or supporting posts. l

I have described hereinbelow by way of example a form of execution of my invention.

In the accompanying drawings:

Fig. 1 is a diagrammatic perspective View of the said form of execution of the covering means.

Fig. 2 is an end View thereof.

Fig. 3 is a plan of the same covering.

Figures 4, and 6 are cross-sections of one bay between two consecutive arches made respectively by planes AA', BB and CC" of Fig. 3.

40 The roof of covering means comprises a series of metal covers l adjacent or very near one another and connected through butt straps l0 for the ow of rain water and the like.

Said covers l may resist to a rather consider- 45 able longitudinal traction but owing to their length they could not by themselves remain rigidly rectilinear and their own weight would cause them to bend downwards; it is thus necessary to support them at intermediate points.

To this end, arches 2 are provided above said covers, say, as represented on the drawings one arch for six rows of covers; said arches being of any convenient form, say constituted by box girders. The covers I act as rods for said arches, 56 and in order of distributing the thrust stresses exerted by said arches between all the rows of coversl, the arches 2 are connected transversely by braces 3, generally shaped as parabolas and are connected by means of stays 4 to the ends of the covers. 5

Struts 8 may be inserted between adjacent arches for stiffening the whole arrangement.

In order to maintain the covers at intermediate points of their length, the arches 2 are further connected to one another by curved members 5 disposed in vertical planes, say under the struts 8, and constituted by ropes, chains, girders or the like, said members 5 being connected to the arch girders and to the covers by stays 6 of any convenient form. 15

The whole is supported by posts 1, walls or the like.

What I claim is:

1. Covering means for buildings, sheds and the like comprising a plurality of transversely curved covering elements lying parallel to each other and arches extending longitudinally throughout the length of said elements and of which said elements form the tie-rods.

2. Covering means for buildings, sheds and the like comprising a plurality of transversely curved covering elements lying parallel to each other, arches extending longitudinally throughout the length of said elements and for which said elements form tie-rods and means for suspending the covering elements at intermediatev points of their length from the arches.

3. Covering means for buildings, sheds and the like comprising a plurality of groups of transversely curved covering. elements lying parallel to each other, an arch for each group of elements extending throughout the length of said elements, the elements of each group forming a tie-rod for the arches to either side of them, curved members connecting transversely the cor` responding ends of each two adjacent arches and stress-transmitting means inserted between said curved members and the outer end of different covering elements.`

4. Covering means for buildings, sheds and the like comprising a plurality of Ygroups of transversely curved covering elements lying parallel to each other, an arch-shaped box girder for each group of elements extending throughout the length of said elements, the elements of each group forming a tie-rod `for the arch-shaped girders to either side thereof, curved members connecting transversely the corresponding ends of each two adjacent box girders and stresstransmitting means inserted between said curved 55 y including a curved member connecting said.vl

arches and vertical suspending elements between said curved member and the underlying coverying elements.

6. Coveringmeans for buildings, sheds and the like comprising a plurality` of l,groups'of transversely curved' covering elements lying parallel to each other, an arch-shaped box girder for each group of elements extending throughout the /length of saidelements, the elements of each group formingl a Vtie-rod for the arch-shaped girders to either side thereof'ami` transverse suspending means arranged in vertical planes between each two adjacent arches including a curved member connecting said arches and vertical suspending elementsbetween said curved member and the underlying covering elements.

- '7. Covering means for buildings, sheds and the like comprising a plurality of groups oi transversely curved covering elements lying parallel to each other, and an arch-shaped box girder for each Igroup of elements extending throughout the length of said elements, the elements of each group forming a tie-rod for the arch-shaped girders to either side thereof, transverse suspending means arranged in vertical planes between each two adjacent arches including a curved member connecting said arches and vertical suspending elements between said curved member and the underlying covering elements, further curved members connecting transversely the corresponding ends of each two adjacent box girders and stress-transmitting means inserted between said curved members and the outer end of different covering elements.
