1 Claim.
My invention relates to roof structures of the type illustrated and described in my former patent, 1,806,685 of May 26, 1931, that is to say, of roof structures made up of supporting beams, of roofing plates having upwardly extending ribs or flanges at their side edges and a hood like structure extending along the center of the plate from the lower edge toward but not to the upper edge of the plates, said roofing plates being arranged in alternately staggered rows and with cap pieces spanning the upwardly extending flanges of adjacent plates and lying on their upper ends beneath the hoods of an upper row of roofing plates, said cap pieces being provided with means for securing them to the roofing beams. As heretofore constructed, the means for securing the cap pieces to the roofing beams have not proved entirely satisfactory and also trouble has been found to occur in securing and holding the cap pieces in proper position upon the adjacent roofing plates over the edges of which they extend and the object of my invention is to supply improved means for securing the cap pieces to the roofing beams and my invention consists primarily in a novel construction of locking means for securing the cap piece to a roofing beam which will be best understood as described in connection with the drawing forming a part of this specification.
My invention will be better understood as described in connection with the drawing which forms a part of this specification and in which Figure 1 is an isometric view of a portion of a roof structure involving my improvements with portions broken away and shown in section to illustrate features of construction.
Figure 2 is a central longitudinal section through a cap piece.
Figure 3 is a cross-sectional view on the line 3-3 of Fig. 2, and
Figure 4 is an isometric view of the locking bar element of my improved construction.
A, A, indicate roof beams. B, B, etc., roofing plates supported, as shown, upon the roof beams and which are formed at their side edges with upwardly extending ribs or flanges B and at their centers with hood like formations B extending from their bottom edges upwardly toward but not to their top edges. These plates are provided at their tops with downwardly extending lugs indicated at B B adapted, when the plate is laid upon the roof beam to engage with the upper edge of the roofing beam and prevent downward slipping of the plate. C, C, represent cap pieces of arc shape in cross-section which,
in the erection of a roof, extend over the upwardly extending lateral flanges of adjacent plates and rest upon the plates. At the lower ends of the cap pieces they are formed with transversely and downwardly extending webs, as indicated at G which should extend below the sides of the cap pieces so that when assembled in a roof they will rest upon or closely approach the surface of the underlying roof plate in the next succeeding row. At the upper ends of the cap pieces I provide transversely and downwardly extending webs C adapted, when the roof is assembled, to rest against the upper ends of the roof plate flanges B and prevent the cap pieces from slipping downward. D, D, indicate lugs extending downward from the top of the cap pieces and adapted in an assembled roof to extend downward between the side edges of the roofing plates spanned by the cap pieces at a point somewhat above the upper side of the roof beam. As shown, these lugs are perforated, as indicated at D to receive the hook end of a hook bolt and are formed with ribs D along their side edges, the lower ends of which ribs, together with the connecting web D at the bottom of the lug, form a seat adapted to engage one end, E of the locking bar E, said end E being provided with a notch E adapted to engage the web of the lock and shaped to lie in between the ribs D of the lug D. The locking bar E is preferably formed of a somewhat U shape having a short arm E on which the lug engaging end E is formed with a long leg E' adapted to rest at its end against the flange of the roof beam and with a connecting portion E through which is formed a bolt hole as indicated at E F is a hook bolt having at one end a hook as indicated at F which is engaged with the perforation D of the lug D and with its other end threaded as indicated at F The body of the hook bolt extends through the bolt hole E in the locking bar E and the locking bar is clamped against the end of the lug D and against the flange of the roof beam by means of a nut G, preferably a wing nut, screwing upon the end of the hook bolt F.
In assembling the elements making up the roof, the roofing plates of each row are set side by side with their upper ends resting upon a roofing beam and with their lower ends resting upon the upper portions of an underlying row of plates set in staggered relation to the upper row of plates. The cap pieces are then placed in position, spanning the flanged edges of adjacent plates and with their lugs D passing down between said adjacent plate edges. The hook bolt F is then engaged with the opening B in the lug D and the locking bar E is then placed in position with the hook bolt extending through its bolt hole E the end E engaging the lower end of the lug D and with its end E resting against the flange of the roof beam. The wing nut G is then screwed upon the end of the hook bolt F and against the connecting portion E of the locking bar E to clamp the locking bar against the beam flange and against the end of the lug D and by the pull exerted on said lug to clamp the cap piece firmly against the roof plates and through the pressure exerted by the cap pieces to hold the roof plates firmly in position in the make-up of the roof structure and this construction of locking means has proved effective and satisfactory as a means for securing the elements of the roof structure in position and together as against all forces of vibration, expansion and contraction and other forces tending to displace the different elements with respect to each other.
In assembling the roof elements as described, the downwardly extending web (I at the upper end of the cap piece extends downward over the ends of the flanges B of the roofing plates, thus insuring that the cap pieces shall be properly located in the assembly of the roof and that it cannot, under any circumstances, slip downward beyond the point where the web contacts with the ends of the lateral flanges of the plates.
Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:
In a roof structure made up of roof beams, roofing plates supported on said beams formed with upwardly extending ribs or flanges on their side edges and with a hood like structure extending from the bottom edge of the plate centrally upward toward but not to the top edge of the plate, said plates being set in successively staggered rows and of cap pieces adapted to extend over said flanges of adjacent plates and secured to the roof beams, the improved means for securing the cap pieces in position which consists in providing the cap pieces with a downwardly extending lug perforated to receive the hooked end of a hook bolt and formed on its lower end with a seat adapted to engage one end of a locking barand in combining therewith in the erection of the roof, a locking bar adapted to engage with the lower end of the lug of the cap piece and to rest upon a flange of the roof beam, said locking bar being provided with a bolt hole to give passage to a hook bolt, a hook bolt engaged in the lug of the cap piece and extending through the bolt hole in the locking bar and a nut screwing on the lower end of the hook bolt and against the underside of the locking bar.
