This invention relates to a nailing strip of that type adaptedto be embedded in a. concretestructure with a portlon exposedto receive nails whereby flooring or the like.
5 may be fastened in place. Heretofore it has been the practice to use woodstrips for this purpose but these soon rot or are otherwise rendered inefficient.
' nailing strip which can be readily'embedded in the concrete and, when thus positioned, will not deteriorate because of moisture, this being due to the fact that air is free to circulatethrough the'strip,
1 It is another object to provide the strip any point to which it might be driven intothe strip. V
A still further object 1s to provide av debe used asreadily as nails.-
it-h the foregoing and other objects in view which will appearv as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment ofthe'invention herein disclosed may be made 'withinthe scope of what is claimed without departing from the spiritof the invention. 7
In the accompanying drawing the preferred form of the invention has been shown. In said, drawings, 1 Figure 1 is a sectionthrough the structure constituting the present. invention, the said strip being shown embedded'ina concrete 'nailingstrip is made-integral with the 'side 3 andis normally extended close to the rolled It is an object of the present invention to. provide an all-metalagainst the top of the nailingstrip. vice of this character in which screws may structure with a layer of wood fastened therereference, 1 designatefithe bottom of the nailing strip from which are extended upwardly convergingfiat sides 2 and 3,"the side 2 having an outwardlyrolled edge etwhereby it is reinforced longitudinally. v The topilof .the.

The strip of wood or thelike indicatedat S to be fastened onthe concrete C is The entir'estrip, including the bottom 1, walls 2 and 3, and top 5,'is formed in asingle .crete form and the concrete, indicated at G,
placed in position and a barbed nail N is drive en downwardly through the strip S and The nail will come against one of the fingers 7 and depressit until the edge 8 thereofcomes into engagement with the side ofthe nail whereuponlit will bite thereinto and hold the nail against withdrawal. Obviously, the nail can be driven'as far as desiredand' will be held securely by the finger engaging it.
gInstead .of using nails, screws can be used and these will be engaged and heldby the fingers in the same manner as the nails.
will constitute a deflector fol-guiding a nail or the like into the strip provided to receive While this structure has been described as designed primarilylfor use in fastening floor ing to concrete surfaces, it is to be understood that it can be usedwhereverstrips of material are toobe attached to the eXposed face of a'concrete structure. As the sides 2 and 3 converge within the concrete,,the strip will be held securely, ,anchored. 7 Those fingers "not depressed'by fastening means will serve to" old t exwalls 2 and?) pr p y Stewed;
