Description

ROOF FRAME Filed May 20, 1932 INVENTOR Fi'ed h. S'feck ATTORNEY Patented Mar. 20, 1934 UNITED STATES PATENT OFFICE ROOF FRAME a corporation Application May 20, 1932, Serial No. 612,520
2 Claims.
This invention relates to roof frames for buildings, and more particularly to portable roof frames for portable buildings.
The general object of the invention is to provide an improved portable roof frame which is simple in construction, rigid and strong when set up in position for use on a building, and which may be readily assembled on a building or taken down as required.
Other objects and advantages will appear hereinafter.
The invention is illustrated in the annexed drawing which forms a part of this specification and in which,
Fig. 1 is a side elevation of one of the trusses of my roof frame.
Fig. 2 is a perspective of one of the securing devices for securing one of the queen braces of a truss to the truss rafter and for securing the 20 adjoining ends of two purlins to the truss rafter, portions of said truss rafter, queen brace, and purlins being shown.
Fig. 3 is a perspective of one of the securing devices for securing a truss to the top plate of a building frame, portions of a truss rafter and tie beam being shown.
Fig. 4 is an end view of the device shown in Fig. 3 for securing the ends of the trusses to the top plates of a building frame, one end of a truss and a portion of said top plate being shown.
Fig. 5 is a longitudinal section of the roof frame taken on line 5-5 of Fig. 1, illustrating the rafters, purlins and queen braces and the securing devices therefore, as illustrated in Fig. 2.
Corresponding parts are designated by the same reference characters in all the views of the drawing.
My roof frame includes a plurality of knockdown trusses 1, as shown complete in Fig. 1, a center ridge 2, and purlins 3.
The securing device 4 for securing together the upper ends of the truss rafters 5, and for securing said ends of the rafters to the center ridge 2 is covered by the patent of Emanuel Berglund, No. 1,504,318 April 28, 1924. The securing device 6 for securing the queen braces 7 to the tie beam 8 of the truss is the same as the device 4, for securing the upper ends of the rafters and the center ridge, with the exception of the plate 9 of said device 4, which is omitted.
The securing device shown in Fig. 2 comprises a purlin plate 10 and a brace plate 11. The purlin plate 10 rests against the underside of the rafter 5 and the adjacent ends of two purlins 3, while the brace plate 11 rests against the under side of the queen braces '7 and is formed with a flange 12 at its upper end which rests against the underside of purlin plate 10 and under the rafter 5. The brace plate 11 is secured to the queen brace 7 by bolts 13 and 14. The purlin plate 10 is secured to the underside of the rafter 5 while the flange 12 of the brace plate 11 is secured to the underside of said purlin plate by a bolt 15 and nut 16. The ends of the purlins 3 are secured to the purlin plate 10 by bolts 17 and nuts 18.
The securing device shown in Fig. 3 for securing the ends of the trusses 1 to the top plates 19 of the building comprises a truss plate 20 formed at its outer end with a horizontal flange 21 outstanding from its lower edge. The plate 20 is secured to the side of the tie beam 8 and the tie beam and adjoining rafter 5 by bolts 22 and 23 and nuts 24 and 25, the bolt 22 extending through the tie beamand the bolts 22 and 23 serving also to detachably secure together the adjoining jointed ends 26 and 27 of the tie beam and rafter. The horizontal flange 21 rests upon the top plate 19 and is secured thereto by bolt 28 and nut 29, whereby the ends of the truss are detachably secured in place on the top plate.
My roof frame may be readily assembled by bolting the truss plate flanges 21 to the building frame top plate 19 and by bolting the purlins 3 to the purlin plates 10, and the frame may be readily detached and taken down upon unbolting the truss plate flanges 21 from the building frame top plate 19 and unbolting the purlin plates from the purlins.
Having described my invention I claim:
1. In a roof frame, a purlin plate resting against the under side of a truss rafter and two adjoining purlins, means for securing said plate to said purlins, and a brace plate secured to the underside of a truss queen brace and formed with a flange, and means for securing said flange to said purlin plate and said purlin plate to said rafter.
2. In a roof frame, a purlin plate resting against the under side of a truss rafter and two adjoining purlins, bolts and nuts for securing said plate to said purlins, a brace plate resting against the under side of the truss queen brace and formed with a flange resting against the under side of said purlin plate, bolts and nuts for securing said brace plate to said queen brace, and a bolt and nut for securing said flange to said purlin plate and said purlin plate to said rafter.
