Y My invention relates to an improvement in the manufacture of flat asbestos-cement roofing and Walling sheets of a form to be applied directly to the vertical supporting' frame 5 member of a building without sheeting 'or other horizontal supports underneath and Y without overlapping of thesheets at theirv sides. These relatively thin, flat asbestoscement sheets of single thickness unitary ma- 10 terial when used as stated above, vare characterized b y `certain ldefects, that have very v much limlted their use for the purposes stated andcaused them to be more or less unsatisfactory When so used. One of these defects is that in their single unitary thickness of material they are too iiexible and too brittle so that when made of any usable practical width they are too easilybent andbroken by heavy Wind and ther loads and strains or by impacts. Another defect is that their imperviousness to Water absor tion is too 4-low I' .and unreliable, and another efect is that the thermal non-conductivity of the sheets is too j low to properly insulate the building against .heat and cold. v
y It is the rincipal object of my'invention to lixesel stated Vdefects so that the use y of the flat asbestos-cement sheets in question in the way and for the purpose stated may be widened and their usefulness improved. A
Reference is to be had to the accompanying drawings forming a art ofthis specification, it being understoo that the drawings are merely illustrative of one example of the invention Figure 1 is a perspective view of a fragment of the fiat asbestos-cement roof and wall sheet and formed in accordance with my invention; and
40 Figure 2 is an enlargedy section on the line 2-2 of 'Figure 1.
To secure the objects of my invention in my improved form of iiat asbestos-cement sheet, I appl tothe inner side of the outer primary at 'sheet 10, and preferably using the rougher surface thereo as ordinarily -produced for the-inner side, a properly proporti'oned coat or layer of a suitable magnesium,
oxy-chloride-silex-silica sand, or high alu- 59 mina Portland cement mortar y11 ofa considing and siding sheet.
erably higher tensile strength than the primary sheet 10, and of a suitable thickness proportional to'thatrof the primary sheet, l
and I imbed in saidlayer 11 a woven metal wire mesh reinforcing element 12 of size sufficient to materially increase by thev well known pro erties of metal reinforcement of cement wor t thestii'ness and transverse strength of the outer' asbestos-cement sheet, and thus united to form therewith a-substantial and the compound form of sheet so produced.
-material increase of the tensilestrength' in 'lo the above metal reinforced'cemcnt, Y k
coat or layer before itsprimary set I Aapply a sheet 13, or a series of elements to constltute a sheet, of a high grade preferably vegetable base thermal non-conductor, such as corkboard'or the like, using that kind of cement mortar in each case best adapted to adhere to both the asbestos-cement primary outer sheet -10 and also the kind of inner insulating sheet used. The said insulating lining sheet l13 is preferably made of a narrower width u than the primar sheet so as to leave a bearl ing portion of t e primary reinforced sheet in direct contact upon the vertical frame supporting member.
`The assemblage of united ele-ments above described results in a thermal resistivity many times vthat of a simple single thickness sheet generally employed :for -the same purpose. Not only is the excessive sun heat thus stopped fromenteringthe building hut all humidity inside as now resulting from constant rains outside permeating the sheetsto the inside is completely stopped by the united insulating lining, while all internal condensation now of common occurrence underneath the naked asbestos-cementsheets is completely eliminatedbecause the inner insulated surface of the united sheet `is kept at or near the room temperature regardless of the humidity within and the colder air Without, .the layers affording thus with their added strength a satisfactory and leconomical roof- It will be apparent that any desired additional insulation or surface finish needed may be applied to the inner surface of my i cement shelter sheet, an inner surface sheet improved sheet in between the uired. would statefurthermore that while-the villustratedexample constitutes a practical embodiment of my invention, I do not limitmyself strictlyto Athe exact detailsherein illustrated, since, manifestly, the samecan be considerably varied. without departure from the spirit of the invention as defined Ain the appendedvclaims.
