ExraNsroN-.TOINT STRIP.
Application mea october 31, 1921. l serai No. 511,850.
following is a specification.
This invention relates to expansion joint strips,v i., e., strips of material commonly placed between adjoining slabsof concrete or the like to allow for contraction and expansion thereof.
ofthe strip.
" far described corresponds substantially toI The'more specific object of the invention is the provision of a strip of the type re-Q ferred to, which is better Vadapted for paetical use than expansion strips heretofore used.
Expansion joint strips heretofore madev generally had as outside layers felt satu- -rated with a water-resisting material, usual-y ly asphalt or other bituminous material. The sole function of these layers of felt was Ito maintain the expansion material proper In contradistinction to this practice,` the present invention comprises a layer`of waterproof, adhesive material, preferably of the expansible compound, on one or both sides In the drawings, Figs. 1-14 represent crosssections of various forms of strips embody` ing the invention.
In .common with `the .usual practice, the expansion joint strips of the invention essentially include a body A .of asphalt compound which may be applied as 'a single yrelatively heavy layer or .in a plurality of layers. Furthermore, in common with the usual practice employ layers of felt saturated with a waterproofing solution.
In Fig. 2 the expansible compound, or asphalt compound in particular, is contained between twovlayers of saturated felt or raw waterproofed felt B. The arrangement thus usual constructions heretofore applied in practice. In accordance with` the more specie object of the invention, however, I provide the outside surfaces of the felt with layers C of an adhesive waterproof material which, generally, may be asphalt compound. These layers are of considerable practical rforms of" the invention. however, that the strip proper may assume l importance inasmuch as they provide a binder betweenthe body of the strip and the adjoining faceof the block or slab. As the successive blocks or slabs are formed, they press the strip firmly against the finished j block and under thispressure the compound fof'the outside layers enters the pores of the material thereof and effectively bonds thel The strips may thus be readily shipped and handled just like the strips heretofore used. WhileA the construction just described serves best the purposes of the invention, 1n some cases'only one outside surface C of adhesive compound is sufficient. The construction shown in Fig. 1 is essentially like that shown in Fig. 2, but a layer D of adhesive compound 1s provided only on one of the layers B of felt.y j f The construction illustrated in Fig. 3 consists of only one layer B of felt to which are applied, on opposite sides, layers A1 and A2 ofthe compound. `Vlfhilethis form of construction necessarily cannot have'the same range of compression and expansion movement which is limited more or less to that of the felt, it emphasizes the importanceof bonding the strip to the faces of the adjoining blocks.
The construction in Fig. 4 consists of two layers A3`and A4 of compound on opposite sides of a sheet E of burlap and two layers C of felt on the outside. On the outside surface of one4 of the layers of felt is provided a layer D of the adhesivecompound.
In the foregoing I have described various It is understood,
many forms, such as at present in use or as may be developed. The essential point is the provision of a layer ofwwaterproofad-A hesive material on one or both outside surfaces of `the strip for forming a bond loetween the latter and the adjoining blocks or slabs.
While I have made referencev only to blocks or slabs, I have done so merely as a matter of convenience. The invention, as is obvious,;is applicable to all cases in which expansion :strips are or can be used.
kHaving described my invention, what I 5 claim. as new, and" desire to. secure by Letters Patent,l is:
1.v An expansion joint strip comprising a layer of impregnated felt, a relatively thick layer of .asphaltic material upon one side 10 of said felt, a relatively thin layer`- of asphaltic material upon the'opposite side of said felt, `a second layer of impregnated i felt contacting with said thicker. layer of asphaltic materialt and a coating' of finely 15 divided non-adheslve material on the outer face'of said thin layer of asphaltic material.
.2. An` expansion joint strip comprising two layers of im' regnated fabric, a' relatively thick. layer o asphalticmaterial ,between the said layers of fabric, a relatively thin layer of asphaltic material upon the outer surfaces of the layers of fabric and a coating of inelydivided nonadhesive material on each of said thi'n layers.
3. An expansion joint strip including a layer of felthaving on one side a thick layer of asphaltic material and on the other side 'a 'thin layer of water roof adhesive material, `and a coating of fine y divided non-adhesive material covering the thin layer.
In testimony whereof I aiix my slgnature.
