7 Claims. I 1

This invention relates generally to buildings and more particularly to aircraft hangars.

It is an object of the invention to provide an arch rib building including a large doorway in an arched side wall of the building.

Another object of the invention resides in the relative arrangement of the building structure in a building of the above mentioned character.

Another object of the present invention is to provide an arch rib building of new and improved construction adapted to embody an overhead door closing a large doorway in the arched wall.

Another object of the invention is to provide a new and improved door for closing an opening in the side wall of an arched roof building.

Other objects of the invention will become apparent from the following detailed description taken in connection with the accompanying drawings in which:

Figure. 1 is an isometric view of a building embodying features of the present invention;

Figure 2 is a fragmentary isometric view of one end of the building framework; and

Figure 3 is a cross-sectional view of the building. I v

In the drawings, which illustrate a preferred embodiment of the invention, the building shown comprises in general, a foundation I0, spaced end walls II and an arched roof-side Wall structure I2. The lower, arcuate portions of the structure 12, designated generally by the numerals I3, It are hereinafter referred to as side walls although they are continuations both in contour and construction of the arched roof. The end walls I I and the side wall I3 seat on the foundation it which may be a suitably wide concrete slab extending along and beneath these walls. This foundation is preferably partially embedded in the ground and anchored by suitable concrete footings I5. In the building side wall I4 there is a large doorway I6 to accommodate large vehicles, such as airplanes, the doorway I6 extending in width preferably substantially the entire length of the building. This doorway I 6 is clo'sable by'a single overhead door,

, designated generally by the numeral H.

ribs I8 terminate adjacent the top of the doorway It where they are connected together by a door frame header 2I which extends the full width of the doorway. The door frame header 2I is preferably of general channel form to receive therein, end portions of the ribs I8 which are preferably welded to the header. The roof and side wall structure I2 may be covered by any suitable sheathing material, preferably steel sheets arranged in overlapping relation, spanning preferably three or more of the ribs to add rigidity to the framing and to reduce the number of purlins required. I I

The building end walls I I are preferably of like construction, each comprising, an end, arched rib I8, a foundation plate 22, a plurality of studs 23 and suitable exterior sheathing. The, studs 23 have their lower ends seated on and secured to the foundation plate 22 which in turn is secured or anchored to the foundation II). The upper ends of the studs 23 may be welded or be otherwise suitably secured to the end wall rib I8 and the exterior sheathing may be suitably secured to the end wall framework.

The doorway frame includes opposite side frame members 25 which aid in supporting the door header 2|. These side, frame members 25 may have their upper ends welded respectively to opposite ends of the header 2| and the lower ends of the doorway side frame member 25 may be welded or be otherwise suitably secured to the end wall foundation plates 22. As shown, the doorway side frame members 25 are angularly disposed extending downwardly and inwardly from the door header 2I to the foundation plates 22. Similarly angularly disposed, an end wall stud 25 has its upper end secured to the end of the end wall rib, adjacent the door header 2| and has its lower end secured to the foundation anchor plate of the end wall. Each of the end walls is further reinforced by a short stud 21 which is secured, preferably by welding at its upper end to the end wall rib I8, and is secured at its lower end to and intermediate the ends of the angularly disposed stud 26. At opposite sides of the doorway, the end wall sheathing may be brought around spanning the angularly dis posed studs and the similarly angularly disposed side frame members 25 of the doorway framing as at 28, Figure 1.

Within the building, intermediate the doorway frame and the roof crown, a reinforcing or truss structure 38 is provided to strengthen the building in the vicinity of the doorway. The truss is supported by a pair of spaced columns 3| located within the building respectively at or adjacent to the building end walls Lower portions of the columns 3| preferably are embedded in concrete footings 33, partially sunk in the ground. The truss 33 comprises a plurality of frame members including a lower beam 34 and an upper beam 35 connected and mutually reinforced by struts 3?. The struts 31 may have their opposite ends respectively secured, preferably by welding, to the

beams

34, 35. These

beams

34, 35 extend in substantially horizontal parallel relation throughout the length of the building, transversely to and supporting the ribs l8. The opposite ends of the lower beam 34 and the upper beam 35 are rigidly secured, preferably by welding to the columns 3| adjacent the upper ends thereof. The ribs i8 rest on the upper beam 35, preferably being welded thereto to provide a strong rigid frame construction. A beam 36 is disposed forwardly of the truss 30, extending parallel with the truss beams 34,- 35. The beam 35 supports and ties the ribs together at points intermediate the upper beam 35 and the door header 2|, the beam 35 preferably being located substantially in the same horizontal plane with the lower truss beam 34 as seen in Figure 3 of the drawings. This beam 36 is supported and reinforced along its length by spaced horizontal connecting members 33 which rigidly connect the beams 33 to the lower beam 34 of the truss 30. Opposite ends of the reinforcing connecting members 38 may be welded respectively to the

beams

34 and 36. Preferably the truss supporting columns 3| are additionally supported by tie rods 40 located respectively adjacent the opposite end walls II of the building and anchored to the concrete footings l5.

The door hasa framework including a plurality of laterally spaced, arcuate ribs 42 of the same general contour or curvature as the roof ribs I8. These door ribs 42 may be rigidly connected together by top and bottom horizontal door frame members 43, 44 respectively, preferably channel members fitting over and welded to the ends of the ribs. At opposite ends of the door are triangular frame members each comprising an upright side frame member 45, a right angle or bottom frame member 46 and a connecting frame member 4?. These frame members 45, 46, 41 are rigidly secured together at the corners by connecting plates 48 welded thereto. At each end of the door the upright frame member 45 constitutes the chord of the end door rib 42, being rigidly secured to the top and bottom door frame members 43, 44 preferably by welding. These triangular frames together with the end arcuate door ribs 42 form the end wall framing of the door. Metallic sheets 50 or other suitable sheathing may be used as an external covering for the end frames and also for covering the door ribs 42. The slope of the frame members 47 is preferably substantially the same as the corresponding slope of the door side frame member 25 to align therewith when the door is in closed position.

Within and at each end of the building, a stanchion is provided, extending upwardly in spaced relation to the adjacent column 3|, a lower end portion of the stanchion 5| being embedded in the concrete footing 33. At its upper end, each of the stanchions 5| is preferably, rigidly secured to the parallel, adjacent column 3| by a pair of connecting plates 52 welded or otherwise secured thereto. Below these plates 52 the stanchion 5| and the column 3| have aligning apertures to support a horizontal Shaft 53. Pivoted on each of these shafts 53 there is a door operating lever 54 having a forwardly extending arm 55 positioned inside the end walls of the door H. The outer ends of the lever arms 54 are secured, preferably by welding, to the ends of a truss cross frame member 53. The cross frame member 56 extends between and parallel with the top and bottom door frame members 43, 44 also connecting the door ribs 42 together, thus adding to the structural rigidity of the door frame. Inwardly of and substantially parallel with the cross frame member 56 is a second, truss cross member 51 connected therewith by laterally extending connecting members 58 to provide a rigid truss structure, connecting and reinforcing the door and door operating levers. This cross member 51, like the upper cross member 53, may have its ends welded to the pair of door operating levers 54, the cross member 51 adjacent its opposite ends preferably being secured by corner brace plates 59 to the lever arms 55 for added rigidity. On the opposite ends of each of the door operating levers 54, a suitable counter balance 60 is provided acting to swing the door upwardly about the fulcrums of the levers 54.
