5 Claims.

The present invention relates to sheet-metal roofing and roof structure and more specifically to a new and improved form and arrangement of partsby the use oi'whichan improved'roofstru'c- 'ture may be produced.

A 'largenumber of forms of heretofore been devised, but those which have proved-commercially satisfactory have heretofore been "of complicated construction. It is, therefore, a primary object of the present invention to provide a type of roof and roofing structure which is greatly-simplifled bothas to manufacture and assembly.

A further object of the present invention is the provision "of a readily 'demountable roof structure which is inexpensive to manufacture, and easily assembled in the field by ordinary workmen without the need for'speoial tools.

A further important object of the invention is the provision of a roof formed of panels detachably connected together to present a strong and rigid construction.

A further important object of the invention is the provision of a prefabricated panel forincorporation in a roof construction.

Astill further object of the invention is to provide an improved form of ridge member adapted to interlock with the upper portions of the roof panels.

A still further object of the present invention is to provide an improved form of eaves structure adapted to have interfitting engagement with lower portions of the roof panels.

Other objects of the invention will become apparent to those skilled in the art from the following detailed description taken in connection with the accompanying drawingswhich disclose a preferred embodiment of the invention.

Figure 1 is a vertical sectional view of a'lower portion of the roof of the present invention;

Figure 2 is a plan view of the construction shown in Figure 1;

Figure 3 is a vertical sectional view of an upper portion of the roof of the present invention;

Figure 4 is a sectional viewof the construction of thereof at the gable;

Figure 5 is a sectional view 5-5 of Figure 1 Figure 6 is a sectional view taken on the line 6-6 of Figure 1;

Figure 7 is a front view of a portion of the structural element forming a part of the roof panel; and

Figure 8 is a sectional view thereof.

Referring to the drawings, the roof is made up of aplurality of panels 10 of novel construction. Asseen in Figure 6, each panel is made up with special structural elements termed modified C-shapes. Each 0-shape is formed of a web l2, flanges l3 and flange extentaken on the line metal roofing have herein sometimes :surface of the sheathing.

sions l-Ai-nclined at an acute angle to the flanges l3. An external sheathing member 15, whichm'ay be of any desirable material but preferably metal, is provided with flanges I 6 arranged'at an acute angle to the plane of the sheathing member. A structural member ll is tacked or integrated to sheathing member P5 in any suitable manner, preferably, if sheathing member i5 is forme'd'of metal, bye-line of spot welding 'I 1 between flange l3 of the C-shape and the sheathing. Asseenin Figure 1, sheathing I5 isprovided at its lower edge with a downwardly inclined flange 18 having a reversely bent extension l9 terminating in .a short section 20 spaced from the lower race-oi the sheathing member 'a distance equal tothe thick ness of the metal fora purpose to be later described. Theupper edge of the sheathing is provided with a flange 2 l forming an angle with the In final assembled position this is an acute angle (Figure 3:)

Figure 6 shows the: manner in which two adjacent panels are joined together'to form a weather- 'tight joint. With the ends of the two panelscontiguous and the O-shapes arranged with the web portions in contact, a spline or key member 22 having flanges disposed at angles'corresponding to the angles of sheathing flanges I6 is slid into locking position as shown.

In Figure 4, a modified form of panel to be used at the gable ends of the roof is shown. In this form, the sheathing 23 has one edge providedwi'th an upturned flange 24 .similar'to panel flange 16 in order to receive a spline '22. The other edge of sheathing 23 has a downwardly directed flange 25 secured to a gable member v215 by means of 'sell-threadingscrews "21. As seen in this figure, additional securinglneans in the form of spot welding I! may be used.

Referring to Figure 3, the ridge roll or cap 28, which extends the length of the roof, is shownas being formed with a circular roll 29 and extending flange portions 30. Flange portions 30 are reverselybent to form rearwardly extending portions 3| lying against flange portions :30. Por- .tions 3-! are bent downwardly to form inclined walls 32 and then forwardly to provide portions 3-3. The distance between portions 33 and 31 is substantially equal to the thickness of spline member 22. The angularity of inclined wall 32 :is

' complementary to the angularity of panel flange 2| in order that wall 32 may lie against and contact flange 2|.

Referring to Figure 1, the space between the edge of the roof and the walls of the shelter may be covered-by a specially constructed eaves member 34 which may run the length of the roof The caves member comprises a web portion having a depending flange 35 secured to wall 38 by means of self-threading screws 31 and an upper flange 4| frictionally received between flange 20 and the lower surface of sheathing member l5.

As shown in Figure 1, the roof supporting meanslcomprise a plurality of channel shaped horizontal beams 39. Each beam consists of a web rtion 40 and upper and lower flanges M and 4 Self-threading screws 43 pass through lower flange 42 and fasten the beam to channel member 44 forming a part of the wall structure of the shelter. The outer ends of the beamsare suitably cut away to accommodate thesloping roof and inclined eaves member.

The roof or the present invention i carried by a novel wall structure forming a separate invention disclosed in copending application Serial No. 485,416, filed May 3, 1943, by the presentinventors.

In assembling the roof of the present invention, the beams 39 are laid across thetop of the wall structure and secured thereto by screw 43. The roof panels are then assembled as seen in Figures 1 and 3 by boltingthe web portions l2 of complementary panels to each other by bolts 45 to form the sloping roof. The opposite ends of these web portions are bolted by bolts 46 to the ends of the corresponding beam 39. Splines or key members 22 are then slid into position with the upper ends tightly received in the space between flange portions 3| and 33 to form a weathertight joint between adjacent panels. The ridge cap 28 may then he slipped into position with flange 2 I being bent into snugly engagingrelation with flange 32 a seen in Figure 3. The eaves members are then applied by inserting flange 4| into the space between flange 20 and the panel sheathing and securing flange 35 to the wall structure by means of the self-threading screw '31.

The roof may be taken down by merely reversing the above steps. I
