nxeansion Joiner.
flrig'inal application filed E'anuary a,
which Figure l is a perspective view of a portion of a separating strip, made in ac-' cordance with one embodiment of my invention, and Figure 2 1s a cross section of a roadway or other concrete structure, illustrating the application of the invention as a separating strip between the sections thereof.
Referring now to the drawing in details 1 represents a sheet metal strip which is out to the proper dimension and formed with the intermediate projecting portion 2 forming a tongue on one side of the strip and a groove 3- on the opposite side. -The material of the strip at the top and bottom of this tongue and groove structure is preferably formedof upper and lower fla't portions made to receive a covering of compressible bituminous or other suitable material to provide a compressible crown at the top and bottom of the strip.
These separating strips as shown in Fig- -ure 2 are set between concrete sections so as to compensate for the expansion and contraction of the concrete, and it should be 40 noted that the tongue is imbedded in the concrete on one side of the strip, and the groove on the o 'posite side of the strip provides an inter ocking opening which the concrete will fill up. With this tongue and groove construction, not only is the strip firmly anchored between the concrete sections, but the sections themselves are interlocked so to speak, so that they cannot buckle, due to the pressure of expansion.
1922, Serial No. 526,742. Divided and this application filed April 14, 1926. SeriaI No. 101,944.
To further guard against this buckling of the sections, due to expansion, I provide additional reinforcing means, such as the rods 6, which are passed thru openings 7- in the separating strip, with their opposite ends imbedded in the concrete sections. These reinforcing members may be steel bars, metal pins, rods or the like, and will aid the tongue and groove structure in joining the concrete sections together. The mastic crown 4- need not necessarily be applied to the lower end of the strip in every case, since the upper crown will more than likely serve the desired purpose.
From the above it will be noted that the combination of the tongue and groove, and the reinforcing bars -6-, form an unusu ally strong positive reinforcing structure for the concrete sections, so as to avoid any possibility of the same buckling due to expansion, as explained. The openings -7- may be arranged. at properly spaced intervals in the length of the strip'to accommodate the required number of reinforcing rods.
I claim:
1. A. preformed expansion joint, comprising a boardlike body, having a tongue on one side, a corresponding groove on the other side, and a flat portion arranged to one side of said tongue and groove, said joint embodying in its construction a thickness of plastic bituminous material reinforced by sheet material of lesser thickness and having openings for the reception of transverse reinforcing members.
2. A preformed expansion joint, compris- 'ing a boardlike body, having a lateral projection on one side and a corresponding depression on the' other side, and a flat portion arranged to one side of said lateral projection and depression, said joint embodying in its construction a thickness of plastic. bituminous material reinforced by sheet.
metal and having openings for the reception of transverse reinforcing members.
Signed at Chicago, Illinois, this 30th day of March,1926.
