3 Claims.

My invention relates to a covering structure which may be used for a roofing or siding for a building. p Q 7 One objectof my invention is to'provide 'a covering of-substantial construction which may be applied directly to rafters or othersupporting beams of the structure and will. afford complete protection'fro-m the weather, and also serve as a heat reflector and insulation.

Another object of my invention is to provide a connecting joint for the abutting edges of the covering units which will completely seal the joints against ingress of water under any weather conditions, and will provide for the free contraction and expansion of the units resulting from temperature and moisture changes without opening or fracturing the seams, and one sufficiently sturdy to withstand snow and wind stresses and mechanical strains, such as may result from the weight of a man.

Another object of my invention is to provide a covering structure composed of easily constructed units which may be produced'in sizes to meet the requirements of different sizes and shapes of structures.

Another object of my invention is to provide a combined roof covering and sheeting so that the usual board sheeting may be omitted.

Other features and advantages of my invention will appear from the following detailed description taken in connection with the attached drawings.

In the drawings illustrating my invention,

Fig. 1 is a fragmentary plan of the covering as it appears when completed.

Fig. 2 is an enlarged fragmentary plan with sealing compound omitted and parts broken away illustrating the anchoring and tightening means.

Fig. 3 is an enlarged section of the structure taken upon line 33 of Fig. 1.

Fig. 4 is a modification in which the mastic absorbent fabric is omitted from the channels.

Fig. 5 is a modification in which-the mastic absorbent fabric is omitted from the edges of the units.

As shown in the drawing, a slab 5 of fibrous material, preferably plywood, of any desired thickness, has a coating 6 of adhesive mastic material applied to its upper surface and edges, and ashort distance in from its edges on its under surface, over which a thin sheet of aluminum 1 or other metal is adhesively laid. The aluminum or other metal sheet I also overlays the edge of the slab 5 a distance sufficient to allow the rafters.

it to extend below the lower face of the slab and turn inwardly against the lower side of the slab.

Channel or U'-shaped members l5, l5 and l1, l8 constitute the top and bottom anchorages and. supports for the roofing units. The webs of the lower channels H are turned outwardly at their ends to provide flanges 19 which rest upon supporting rafters or other timbers 2| of the struc ture to be covered. The channels it and I! are shown mounted longitudinally of the rafters 2i, and secured thereto by nails 22, through the adjacent plates of the channels, as shown in Figs. 2 and 3. The outer surfaces of the U-shaped members l5, l6 and l1, iii are preferably completely covered by strips of

absorbent fabric

23 and 24, so that when they are brought together back to .back, as shown in Fig. 3, the meeting surfaces are separated by two layers of the fabric.

A strip of fabric or paper or other mastic absorbent material 25 is attached to the surface of the aluminum sheet along its four edges and overlays the top and bottom a distance at least as great as the width of the flanges IQ of the channels. 1

As alternative constructions, the absorbent material may be omitted from the channels as shown in Fig. 4, or may be omitted from the edges of the units as shown in Fig. 5. At intervals, along the channels, the upper and lower channels are secured together by screws 25 of the type that form their own threads as they are turned.

The channels which extend across the rafters are preferably of considerable length so that they will serve to tie the beams together, and if the length of the building is such that joints are necessary, it is preferable that they be staggered. The channels which run upon or parallel with the rafters are preferably cut in lengths to lie between the cross-channels. Where joints are formed between the cross-channels and those lying parallel with the rafters but not over them, the ends of the channels which run parallel with the rafters may be inserted between the flanges of the cross-channels by bending the flanges outwardly.

In originally assembling a roof structure, one channel member is preferably laid crosswise of The nails 22 are driveen part Way home, and the screws 26 are started in their matching openings. Another channel is then loosely nailed along the top of the end rafter at right angle to the first channel. Mastic cement is then brushed into the sides of these channels which are to receive the edges of one of the roof units. One unit is then pressed in place in the channels. The first channel which runs parallel with the rafters is then placed in position with mastic cement within the channel to receive the edge of the first placed unit. When a number of units has been placed across the supporting members from one side of the building to another, the nails are driven home, and the screws tightened so that the fabric saturated with mastic cement is squeezed tightly onto the top and bottom surfaces of the units. After all of the nails and screws have been driven home, the upper channels of the supporting members are filled with mastic material.

If a unit becomes damaged and has to be replaced, the flanges of the channels may be bent upwardly so that the unit may be lifted out bodily. When a new unit is inserted, the edges are covered with plastic cement, and the top flanges of the channels again bent down to lie flush with the upper surface of the inserted unit. The units are of such size as to leave a slight space, as at 21, Fig. 3, to permit expansion due to heat or moisture. The aluminum sheets i are so thin and so securely cemented to the ply wood slabs 5 that the aluminum is forced to expand and contract with the ply wood. The width of the top and bottom flanges of the channels is sufiicient that there will always be a good overlap, even if the slabs 5 contract considerably due to cold or dryness. Even in contraction and expansion, the plastic material at the joints maintains adhesion with the fabric and the channels and the aluminum surface of the roof units.

Although I have shown and described my invention with respect to certain details of construction, and have stated that the exposed metallic sheet is aluminum, it is to be understood that the structure may be modified within the purview of my invention, and that any suitable alloy of aluminum, or any other metal such, for example, as copper or thin stainless steel, may be used.

I claim:

1. In a covering structure for outside surfaces, a plurality of slabs of fibrous material, an ad" hesive covering one face and the edges of each slab, a sheet of aluminum above the adhesive and covering the face and sides of the slab, an anchoring strip secured to the timbers of the structure to be covered, upper and lower laterally extending flanges on each side of the anchoring strip for engaging the side and end margins of the slabs, and adhesive sealing material between adjacent portions of the slabs and the anchoring strip.

2. In a covering structure for outside surfaces, covering units each comprising a slab of fibrous material, anchoring strips for engaging the edge and end portions of said units secured to the timbers of the supporting structure to be covered, said anchoring strips each comprising a pair of channel shaped members, each including a pair of legs provided at the open end with flanges extending at right angles thereto to embrace the edges of all units, and means for securing the channel members together back to back.

3. 'In a covering structure for rafters, covering units each comprising a flat slab of rigid material, anchoring strips secured to said rafters and having side channels for engaging the edge portions of said units, each anchoring strip comprising a pair of channel members each including two webs provided at their open ends with outwardly extending flanges, mastic absorbent fabric between the flanges and the upper and lower surfaces of the units, and means for drawing the upper and lower members of the channel together back to back to squeeze to absorbent fabric between the flanges and the covering units.
