W. In the construction of building roofs and walls;
concrete as a surfacing material has long appeared to be an advantageous low priced and long lived covering, provided the thickness of the material could be reduced to a point where the weight would not be excessive and the amount of material used could be kept down to an economical basis. r
Among the obstacles encountered, however, are the very great difiiculty of curing extremely slabs of concrete and the almost insurmountable dificulty of preventing the cracking of such slabs under curing and subsequently under expansion and contraction. In an endeavor to get away from this, shingle types of construction have been indicated, but here the necessity of even less thickness and the corresponding difiiculty of curing has become even greater. Close fitting of the shingle surfaces where cured shingles are laid, because of the stiffness and inherent rigidity of the material, has also proven to be almost impossible, and the securing of the shingles has proven to be very difiicult because of breaking the shingle in endeavoring to firmly seat and hold it down.
In a previous Patent No. 2,193,233 issued to me endeavor was made with notable success to meet the situation, but even so the resulting structure was inherently relatively massive and expensive.
Supplementing this, further endeavor is disclosed 3 in 'mynow allowed pending application, 340,421, of which the instant application is a continuation in part.
In both of these structures, however, difiiculty has been found in firmly securing the cave edge of the shingle, resulting in some cases in edge curling during curing, and even when this does not occur, leaving them open to the common fault of all shingle structures in general, that the cave edges are not firmly held down, with the concomitant result that dislodging wind may find entrance and snow and rain blow in.
The objects of the present invention are:
To build a concrete roof or wall using a minimum of material and of economical cost; which will be securely attached to the sub-surface structure; which will be securely attached over substantially its entire area, including exposed surfaces and exposed edge portions, and particu larly eave edge portions; which will conform closely to the subsurface structure and to structures overlying the same; which will substantially reduce and compensate for expansion and contraction strains and random cracking incident thereto; which will provide ample protection against leakage where cracks do occur; and which will satisfactorily and economically accomplish the curing of the material.
The means by which the foregoing and other objects are accomplished and the manner of their accomplishment will readily be understood from the following specification on reference to the accompanying drawings, in which:
Fig. 1 is a perspective view showing diagrammatically the sequence of steps in building the preferred form of surface structure.
2 is a similar perspective view showing a modified form.
, Figs. 3, 4, 5 and 6. are respectively transverse sections one much larger scale of the eave edges of typical preferred forms of the structure, and the various steps in laying each thereof, Fig. 3 being a section of the type shown in Fig. l, and Fig. 6, a similar section of the type shown in Fig. 2; and
Figs. '7, 8, 9 and 10 similar transverse sections of further modification forms of the construction.
Referring now to the drawings in which the various parts are indicated by numerals:
H is the roof sheathing. In Figs. 1 and 3, a
sheet it of bituminous paper such as tar or as-' phalt paper is rolled out along the eave edge il-A of the sheathing. The surface of this paper is covered throughout its width and length with a thin layer l5 of rich cement mortar or, if desired, even of neat cement mortar, the mortar being mixed preferably of such consistency that it may be applied with a brush or spray gun; and
endeavor being used to apply this mortar of uniform thickness throughout, the thickness ordinarily accomplished being, according to circumstances, of the nature of to of an inch. Over this freshly spread layer of mortar, an open mesh net i! is laid. In its preferred form this net is of some 9,; inch mesh with warp and woof at right angles, each formed of loosely twisted strands, each strand in turn being of hard twisted heavy cotton fiber, of heavy thread or light cord weight, the net preferably being furnished in continuous rolls conforming in width to the underlying paper and mortar and being rolled out over and pressed into the fresh mortar. After the net is laid, nails It are driven down against the surface of the net and the mortar, these nails being spaced at desired intervals along and ad-' Jacent the eave edge H-A and additionally throughout the entire length and width of the net area. After nailing, an additional layer 2! of the cement m'ortar, of generally the same thickness as the original layer, is uniformly spread as promptly as possible and before the preceding layer has set. Following the placing of the second layer of mortar, a second sheet 23,
of bituminous paper is unrolled and pressed down into intimate contact with the mortar. A surface layer 25 of mortar is then spread uniformly over the just laid paper and following this, a roll of oiled or waxed paper 21 is spread over the surface layer of mortar and pressed into intimate contact therewith.
The upper, edge 21-A of this waxed paper is spaced away from the upper edge 25A of the cement mortar an amount such that it will underliethe next succeeding sheet H3, mortar H5, net I I1, etc., which are laid, and the width of the waxed paper is such that its eaveedge 21-B will extend beyond the eave edges 25-38, l3-B, of the mortar layer 25 and sheet l3 respectively to permit it being folded around these edges and tucked under as shown in Fig. 3, to be thereby held until curing has taken place.
In Fig. 4 a construction is shown conforming to the construction shown in Figs. 1 and 3, with the omission of the paper sheet 23 and mortar layer 25 there shown. In this figure the eave edge 21-3 of the waxed paper 21 is shown extending beyond the eave edge of the sheet HA and the overlying roofing layers prior to being folded and tucked under the eave edges of such roofing layers.
In Figs. 2 and 5, a sequence is followed similar to Fig. 4, except that subsequent to the placing of the mortar layer 2|, a sheet of substantially impervious paper 3| is coated on its underside with a. layer 33 of mortar, and this mortar covered layer of paper is rolled out on, and its mortar facing 32 intimately contacted and incorporated with the mortar layer 2| previously laid. In this form of the roof the upper edge 3l-A of the paper 3| underlies the first layer H3 of the succeeding strip of roofing in manner identical to the similar edge 21A of the sheet 21 (Fig. 1) and the eave edge of the sheet 3| may be similarly extended and folded under, or provided the sheet ll be of suflicient stiffness and Fig. 5 corresponds closely to Figs. 1 and 3,
with the exception that the cement coated paper 3| has been, as in Figs. 2 and 6, substituted for the plain waxed paper 21 of Figs. 1 and 3.
With further reference to Figs. 2, 5 and 6, it will be noted that the edge views of sheet 3| indicate a wavy or serrated sheet, and that the surface of the sheet 3| in Fig. 2 is indicated by irregular markings as crinkly, or other than smooth. It will be understood that the sheet 3| may be smooth and of substantial identity with the smoothjwaxed sheet 21, but the drawings are intended primarily to indicate a crinkled paper which will establisha similar crinkled surface or pattern in the underlying mortar, and which when removed will leave a roofing surface of crinkly or such other pattern or nature as the paper used will give.
Figs. 7 and 8 disclose structures closely following Figs. 3 and 4 with the omission of the fabric. Layer ll of mortar in these views not being overlaid withfabric the covering layer 2| of the previous views is a part of the underlying edges I5 and has no initial separate identity or number.
Figs. 9 and 10 disclose structures following ihe showing of Figs. 3 and 4, with the exception that it has been found that the fabric I1 may be laid directly on the underlying bituminous sheet,
as on the sheet 28 of Fig. 9, or the sheet I3 of such number of alternate sheets and layers may be built up as may be desired, rather than stopping with the two layers there shown, and Fig. 9 the further suggestion that the fabric or other fibrous material may be placed in other than the lowermost layer. In these figures the cover sheet is shown terminating at the eave edge of the roof, but it will be understood that it may be extended and tucked under as in Figs. 1 and 3.
In Fig. 8 the eave edge of the cover sheet is secured by nails 35 which are additional to the nails l9 and are spaced from time to time along the edge to secure this sheet, such construction being permissible in cheap roofs where appearance is not of importance and cost a primary consideration.
It will be understood that in laying the roof endeavor in all cases is made to contact the paper sheets intimately with the mortar layers with as nearly as possible no entrained air. And in laying any of the types here shown, it is found that placing a roll of paper on the mortar surface and unrolling this paper along the mortar surface displaces the air effectually. It is believed that the crinkly paper may be similarly placed by unrolling and similarly displace the air even though the under surface of such crinkly paper he not coated.
.It is found, however, that it is extremely difficult to lay the crink y paper in intimate contact with a mortar surface and definitely displace all air from therebeneath in such laying, and it is found that a more efficient Job can be done by coating the crinkly paper with mortar, and after such coating so rolling the paper that when unrolled this mortar surface will come into intimate contact with the underlying mortar surface over which the paper is spread and effectually solve the problem of displacing the air. 1 Should .'it be found that the entrained air is not'all displaced by rolling out the paper, it is evident that vibration by some of the well known types of vibrating apparatus, perhaps modified to meet the exigencies of the situation, may be resorted to, to effect such displacement.
It has been found difiicult to prevent smooth waxed paper from beingdisplaced from the ,roofing surface during the curing period unless its upper edge slightly underlies the subsequently laid roofing and such underlying is therefore indicated, it being found that such underlying edge may subsequently be withdrawn at the end of the curing period. The eave edge, however,
- Where crinkly paper has been used, however, the
inherent stiffness furnished by the distortions of the paper due to crinkling and adherence of the r 2,280,579 paper have been found to secure it satisfactorily against such displacement, and it is believed that the under-tucking of such edge may in these cases be omitted.
In the above descriptions, reference has been .made from time to time to the eave edge of the roofing. It will be understood, however, that the 'term eave edge, as applied to the first strip of roofing is equally applicable to the lower or eave edge of subsequent strips and. is herein specifically so defined and intended.
It will be understood that in the claims where ,waxed or oiled paper is referred to, such paper paper, be it smooth or crinkly, is removed and the completion of the roof finally accomplished.
The paper used and herein referred to as bituminous paper is preferably paper known commercially as tar or asphalt paper, and depending on the preference of the builder, either may be used. Also some other type of paper or sheet material of similarnature which possesses resistance to water penetration, disintegration and other weather-resistant qualities, maybe substituted for the bituminous paper specified without departing from the spirit and disclosure of my invention.
