4 Patented Apr. 1, ,237,226 UNITED STATES PATENT of FICE RAF. Application January 2, 1940, serial No. 312,134 2 Claims. (Cl 103-1) The present invention relates to new and use ful improvements in steel roof or span construc tions and has for its primary object to provide, in a manner as hereinafter set forth, a structure of this character of novel form whereby a com 8) paratively large area may be covered without the necessity of using intermediate supports, such as posts, pillars, etc. Another very important object of the invention is to provide a roof or span construction of the 10 aforementioned character which may be expe ditiously erected and taken down without the necessity of using special tools or machinery. Still another important object of the invention is a tie rod 4 to prevent spreading, this tie rod including turnbuckles 5 for tightening. Rigidly secured at spaced points on the plates 2 are brackets 6, The reference numeral desig nates generally a plurality of spaced arches of suitable metal which are mounted on the brackets 6. Each arch comprises a plurality of segments 8 having overlapping end portions rigidly se cured together through the medium of bolts 9. Extending between the arches 7 are pairs of crossed braces O. The braces are provided with eyes on this ends which, accommodate the bolts 9. Thus, he same bolts which secure the segments together also secure the braces is to provide a roof or span structure of the char- 15 (0 to the arches. Rings connect the crossed acter described which may be of any desired di braces at the points where they intersect. mensions. Referring now to Figure 1 of the drawings, it Other objects of the invention are to provide will be observed that struts 2 are provided for a roof or span construction which will be com strengthening the arches 7 against distortion. Or paratively simple, strong, durable, light in weight 20 collapsing. The ends of the struts 2 are se and which may be manufactured and erected at low cost. All of the foregoing and still further objects and advantages of the invention will become ap parent from a study of the following specifica- 25 tion, taken in connection with the accompany ing drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein: Figure 1 is a view in side elevation of an em- 30 bodiment of the invention. " - Figure 2 is an elevational view of an end portion of the roof. Figure 3 is a view in vertical section through an intermediate portion of the roof cured to the joints of the arch segments. It will also be noted that the struts 2 are of sufi cient length to skip several of the segments of the arches The reference numeral 3 designates roofing mounted on the arches T. Of course, the roofing conforms to the curvature of the arches 7 and, referring to Figure 5 of the drawings, it will be seen that the sections of said roofing are of sufficient width to extend between the adja cent arches. The roofing sections 3 comprise. overlapping marginal portions 2 which rest on the arches. The portions 2 are provided with interlocked V portions 4 which extend adjacent the opposite sides of the arches. Then, the Figure 4 is a detail view in perspective of one-roofing is firmly secured to the arches through of the plates, Figure 5 is a cross sectional view through a por tion of the roof. Figure 6 is a detail view in perspective of one of the arch brackets. Figure 7 is a detail view in perspective of one of the arch segments. the medium of J bolts 15. Washers 6 of suitable material are-provided beneath the bolt nuts T for preventing leakage around the bolts. It will thus be seen that a metallic roof or span has been provided of such construction as sto obviate intermediate supporting pillars, etc. It will also be observed that the structure may be Figure 8 is a detail view in perspective of one of 4 expeditiously erected without the use of special the arch braces. Figure 9 is a detail view in elevation of one of the rings for the crossed arch braces. Figure 10 is a view in side elevation of a por tion of another form of the invention. Referring now to the drawings in detail, it will be seen that the reference numeral designates a pair of spaced walls. Mounted on the walls are metallic plates 2 which are secured by anchors equipment. Further, the structure may be taken down if desired and there will be practically no loss of material. In Figure 10 of the drawings there is illus 50 trated a modification to be used when unusual strength is desired. This modification comprises inner and outer arches 8 and 9, respectively, which are spaced from each other through the medium of braces In other respects, this. 3. Extending between the plates 2 on the walls 55 modification is substantially similar in construc

5 2 tion to that form of the invention shown in Figs. to 9, inclusive, It is believed that the many advantages of a steel roof or span construction in accordance with the present invention will be readily un derstood and although preferred embodiments are as illustrated and described, it is to be under stood that further modifications and changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed. - What is claimed is: I. A structure of the class described compris ing a plurality of Spaced arches, each arch in cluding a plurality of metallic segments having Overlapping end portions, pairs of crossed braces extending between the arches and terminating, 2,237,226 5 O 15 at their ends, in eyes engaged with the joints of the arch segments, securing elements passing through the eyes and the overlapping end por tions of the segments for rigidly securing said Segments and crossed braces together, and rings connecting the crossed braces at the points where they intersect. 2. A structure of the class described compris ing a plurality of spaced arches, roofing mounted on said arches, said roofing comprising sections including overlapping marginal portions resting On the arches, said overlapping portions includ ing substantially V-shaped interlocked portions On opposite sides of the arches, and means for anchoring the roofing sections on said arches.
