1 Claim.
This invention relates to devices for projecting concrete and has special reference to devices for use to protect newly formed concrete structures against cold and for use in confining heat applied to the concrete during the curing or setting of the concrete.
An object of the invention is to provide a covering device that may be manufactured and sold economically and at comparatively low cost and used satisfactorily as a protection against cold to confine heat against and about newly formed concrete structures so that the concrete will cure or harden without being subjected to the damaging and injurious effects of cold temperatures and other destructive weather conditions and changes.
Another object of the invention is to provide a device for protecting concrete and comprising numerous attached sections of textile material coated on one side with an adhesive substance supporting a layer of paper, or other appropriate material, in connection with the respective textile sections, all of said sections making a flexible substantially inelastic device that may be extended and supported over the concrete structures during the curing and hardening of the concrete and affording all necessary protection against cold and also functioning to confine heat about the concrete when heat is needed to expedite the curing and hardening of the concrete.
Available sources of supply of the sections used to form the composite covering device are known to us and we have successfully made use of such sections of used material which heretofore largely went to waste. By making use of such used sections of material to form our concrete protecting device, We have established an additional use for such waste material and are able to produce these needed concrete protecting devices at much less cost than has heretofore been required to produce other types of concrete protecting devices.
Various other objects and additional useful features of the invention should be readily apparent from the following description, reference being made to the annexed drawings, in Which- Fig. 1 is a plan view, with parts of two of the sections broken away, showing the important features of our improved concrete protecting device.
. Fig. 2 is a view showing our improved concrete protecting device in use to protect a bridge or viaduct structure.
Fig. 3 is a combined plan and detail view of two attached sections sufficiently illustrating the arrangement of the textile material in association with the adhesive material and impervious lining.
Fig. 4 is an enlarged cross sectional view approximately on the line 44 of Fig. 3 showing additional features of the invention.
Used bags, from which the contents have been removed and which used bags have heretofore found no substantial market or further useful application, constitute a sufiicient and satisfactory source of supply from which we may obtain the numerous sections to form our improved concrete protecting devices. Our invention is an embodiment of an idea of means providing a valuable use for materials which have heretofore been substantially without value; but we do not restrict ourselves to the use of used sections to form our improved concrete protecting devices and the invention is not limited to that extent.
Each of these used bags consists of a section of material folded in a relationship in which its edges are approximately even and the edges are attached together along the bottom and along the side thereof until the bag is filled and then the upper end of the sides of the bag are attached together to close the bag. The bag is opened at either end and the contents removed. We utilize these used bags by ripping the seams along the edges thereof so as to permit the section of material to be spread flatwise.
The sections may be cleaned before they are attached together to form the composite device.
As clearly shown in Fig. 4 of the drawings, each section includes a section I of burlap, or other fabric of strong and coarse weave, having longitudinal threads 2 and transverse threads 3. One side of each section I is coated or covered with an adhesive coating 4 of adhesive cement or the like having close adhesive union with all of the threads 2 and 3. A section 5 of imperforate paper, or other appropriate material, is adhesively united to the adhesive coating 4 and is approximately co-extensive with the section I.
The marginal edges 6 of the respective sections are folded outwardly and are attached together by stitches 1 and as many sections are thus attached together as are required to form the concrete covering device of the desired dimensions and we make no restriction in this regard.
Preferably these sections are attached together substantially in the relationship shown in the drawings in which at least two of the section-s A are attached together along their longitudinal marginal edges 6 and have their ends attached to sections B extending transversely of the. sections A and crossing the scams 6, 1. Each section B is also attached to another section B along its longitudinal edges 6 and this arrangement is repeated throughout the structure.
In Fig. 2, our improved concrete protecting device is shown mounted on the side rails 8 of a bridge or viaduct 9 and supported thereby. The device will protect the concrete bridge structure against cold and will also confine heat generated and radiated by heaters or salamanders l 0. Our improved protecting device may be used over and over again without much damage or injury and will last indefinitely. Since the device can be made from used material otherwise without much value, it is clear that the device may be manufactured and sold at relatively low cost. Moreover, the device is a good insulator against cold and satisfactorily confines the artificially generated heat, so that the manufacture or formation of concrete structures may be conducted satisfactorily during quite cold weather.
Without restricting ourselves beyond the extent required by the state of the art, we: claim:
A blanket to be used in covering and curing newly laid concrete, made of a plurality of united substantially square units of discarded fabric bags, each unit composed of two approximately equal rectangular portions joined centrally by a seam and having a flexible imperforate material adhesively united thereto, the plurality of units being so connected that the central seam of each unit is disposed perpendicularly to the central seam of each, contiguous unit.
