2 Claims.
My present invention is a novel and improved covering for use in the various methods of curing concrete structures, particularly in the building of roads and highways. In such outdoor work, as concrete road surfacing, it is necessary to cover and protect the concrete layer or surface by covering the surface to prevent too uneven a drying of the moisture and setting of the concrete, particularly to prevent drying out of the top surface before the entire thickness of the concrete is properly set. Heretofore, various coverings have been employed, particularly straw, earth, or the like, as well as tar paper.
In my present invention I have developed a 5 new and improved construction of paper-like covering, which will be, and is made of appropriate dimensions to substantially fit or cover the section of road surface being built and which will also enable the sides or edges of suitable 0 depth to be covered, and which will effect a substantially predetermined or automatic fitting of the covering onto the surface of the road.
A further important object of the present invention is to provide a substantial curing mat 5 or cover capable of being made in relatively long lengths, such as 50' or 60, suitable for use repeatedly on successive or adjacent lengths of the concrete surface, and which will have means to facilitate the application to and removal from the surface.
In applying such a covering to the work, as well as removing it therefrom and reapplying it at a subsequent section, it has been heretofore extremely difficult to handle long and large cov- 5 erings, but in my present invention I have provided means at each edge which will greatly facilitate the handling, positioning, fitting, as well as removing the mat or cover.
Other important features, advantages, and
novel combinations will be hereinafter more fully pointed out and claimed.
Referring to the drawing illustrating a preferred embodiment of my invention,
Fig. 1 is a diagrammatic view, partly in crosssection of a concrete curing covering as applied to a roadway;
Fig. 2 shows a modified form;
Fig. 3 is a detailed fragmentary cross-sectional view, and
Figs. 4 and 5 are further fragmentary views in perspective of modified forms.
As shown in the drawing, I contemplate the making of a concrete curing cover, preferably of a plurality of parallel strips for convenience in manufacture, although it could be made of a single width, if desired or feasible, such a coverlng having at opposite edges and of appropriate width to cover and protect both the opposite edges of the concrete being laid, depending flanges or portions. Such edge portion, together with the adjacent edge of the surface covering portion, are united either by stitching, cement,
or other means, and present an upturned hand holding ridge, or rim, when the depending flange is fitted on the adjacent edge portion of the con crete. Thus an automatic fitting of the covering is provided, both the top surface and edge portion are covered, and the operators or workmen handling the same have a convenient means of applying the covering, as well as removing and reapplying it to another section.
As shown in the drawing, I prefer to form this covering of a plurality of strips 1, 2, and 3, these being of convenient width for manufacturing purposes for the average 10' strip of concrete. These strips may be of tar paper, or the like. Each'strip is preferably overlapped along the adjacent edges, as shown at 5 and 5, and the same may be united by cement, asphalt, or other adhesive, as illustrated in Fig. 3 at the left porso tion thereof. Along each edge of the outermost strip is secured the flange portion 10, which may also be united to the adjacent edge of the strip 1 and 3 by cement, as shown at 11.
This construction illustrates the simplest form 5 of my concrete covering, as shown in Figs. 1, 2, and 3. The arrangement just described, and as illustrated, permits long lengths of sheet material, for example 60', to be conveniently made, rolled up, transported to the work, and unrolled on the concrete surface to be covered, protected, and cured, and thereupon operators proceeding along each edge, and preferably as the cover is unrolled, will pull out the flanges 10 at each end, fitting them on the edge of the concrete 20, and thus simultaneously covering both the surface and the edge portions, forming a hand holding and protecting ridge 21, and constituting also an automatic and predetermined fitting of the cover to the surface.
This is of great importance in such an article and in the work to which it is applied, since the fitting, removing, and refitting of such a covering involves considerable manual labor and expense. In most instances it is essential that the edge of the concrete be protected, as well as the surface, and the edge portion is then banked by earth, or the like, 22. As shown in Fig. 4 I' have illustrated a similar construction, wherein the strips of covering material 1, 2, and 3 are attached by a series of stitching 24 and the edge flaps 10, 10 are also secured by stitching 25, 25. Such stitching may be either with or without the adhesive layers 11, as above explained, the stitching being mainly for added strength, while the adhesive layers 5 or 11 add to the waterproof features of the cover when thus made in strips.
In Fig. 5 a still further modification is illustrated, wherein the strips 1, 2, and 3 are united by stitching 24, 24, and covered by cementing the strips 26, and 2'7 and over the joints, thus making the same impervious to moisture passing through. If desired, corresponding strips 28, 29 may also be cemented, covering the opposite portions of the stitched joints.
While it is ordinarily desirable to have such a curing cover for concrete roadw'ork waterproof and. moisture-repellent in order to insure even drying and setting of the entire layer of the concrete 20, yet it is sometimes desirable to make a further application of water to the concrete when the same is not setting properly. For this purpose it will be appreciated that I may make the surface of the layers 1, Z, and 3 with recesses I therethrough, and thereupon flow Water over the surface between the ridges 21 to thereby effect a further wetting of the concrete, such a series of recesses being shown for illustrative purposes at 30, Fig. 2, the same being applied, if desired, throughout the other layers of the covering. Also, in case of heavy rains or storms when it is desired to prevent rain or moisture accumulating on the surface between the ridges 21, 21, these may be simply pressed or forced down so as to insure the rain water running oif the surface, this being only required in level stretches, as on hills or grades the water would flow off the ends.
My provision of a combined surface-covering and edge-protecting article for curing concrete, together with the feature of a hand-hold along each edge, and also with an automatic predetermined fitting of the covering to the work to be covered, is believed to be a distinct novelty in this art and I wish to claim this herein broadly.
I claim:
1. As an article of manufacture, a concrete curing cover, comprising a plurality of parallel \strips, a predetermined number of said strips being substantially equal to the width of the work to which they are to be applied, and an edge strip so secured and attached to the cover to contact with the edge of said Work and to simultaneously position the said article to the Work.
2. As an improved article of manufacture, a unitary Waterproof removable cover for curing concrete, having formed on the edge portions means to enable the cover to be fitted on to the work, said means including a flange portion extending sufficiently above the work to provide a hand-hold at any part.
