This invention relates to a parting or dividing strip used between two contiguous sections of a concrete or similar roadway or sidewalk.

Such strips are usually made of sheet metal and are placed at the ends of adjoining sections or between the longitudinal edges of adjoining sections of concrete or similar material. The strip serves as a partition or confining wall and also as a contraction road strip to prevent cracks in the road bed due to contraction resulting from varying temperatures. In extreme cases the strip may not prevent cracking but in such instances it will at least confine the cracking to a positive direction and determination.

Strips of this nature as heretofore manufactured were usually constructed of a single strip of sheet metal deformed in some manner to provide a laterally projecting portion intermediate its longitudinal edges and adapted to be secured to the road bed by means of pins or stakes.

It is the purpose of this invention to provide such a strip but in such a manner as to permit of cheaper construction, greater rigidity and greater ease in handling and shiping. p In accordance with this invention the contraction strip is constructed of one or more longitudinal sections supported upon and secured together by short oining members or battens at proper intervals. The strips are preferably flanged and the securing or sup.

porting members or even the flanges of the longitudinal members may be apertured to receive securing stakes or pins.

By the use of the spaced sections when two or more sections are used the reinforcing bars usually employed in a roadway may be inserted between the sections.

A better understanding of this invention will be obtained from a consideration of the following description given in connection with the drawings in which:

Referring more particularly to the form of this invention,illustratedin Figs. 1 to 7 inclusive it will be seen that the contraction road strip is formed of two angle irons or strips 1 and 2 held together in longitudinally spaced relation to each other by channel shaped securing cross strips or battens 3. It will be noticed that the angle strips 1 and 2 are formed with their flanges bent at an angle less than 90 and are secured together by cross strips 3 with their flanges inwardly opposing each other. The securing strips may be welded or otherwise secured at spaced intervals to the longitudinal strips 1 and 2. Strips 1 and 2 are substantially parallel converging at one end slightly an amount equal to the thickness of the strips. This will permit the telescoping together of the adjoining ends of the succeeding strips la and 2a, and 1b and 2?). At one end these strips 1 and 2 are secured together by a keeper strip 4 which is offset outwardly to provide a flange 6 spaced from strips 1 and 2 the thickness of the strips to permit the insertion of the adjoining ends of the adjacent strips 1a and 2a.

It'follows from the above that the road strips described due to the braced construction may be made of relatively light sheet metal which will permit economical manufacture and cheap transportation without be rigidly secured to the road bed in upright position.

sacrificing rigidity and strength. The over all height of the road strip is slightly less than the over all thickness of the road in order that the upper edge will be slightly below the top surface of the road or pavement. The road strip may be secured to the road bed in upright position by means of stakes 7 U-shaped in cross section. 'These stakes may be driven through the channels or the securing strips 3 as is clearly shown in Figures 3, 6 and 7.

Referringto Fig. 8 the construction there shown is substantially the same as that shown in Figs. 1 to 7 with the exception that the two strips indicated by numerals 11 and 12 haveitheir flanges bent at right angles. As

in the prior modification the twostrips are, secured together by cross members 13.

InjFigs; '9 and there is shown a modi 'fioat'ion in which aesingle angle iron or strip 16is employed and is supported by channeled cross strips 17. The latter strips are flanged outwardly as at 18 to form a foot rest for the completed strip. In this form the end cross f strip '19 is also flanged at its base to provide a footing and is further flanged at its upper edge to provide a tongue 21 offset from the strip 16 and between which the adjoining strip 16a may be fitted.

In Figs. 11, 12 and 13 there is illustrated a still further modified form in which a pair 7 of spaced angle irons or strips 23 and 24 strips which may be used either longitudinally or transversely across a roadwayor pavement and which may be'constructed of rela- 'tively light materials without sacrificing strength or rigidity and that the strips may It is obvious that many changes may be made in the details of'construction withoutdepartingfrom the spirit and scope of the invention as defined in the claims appended hereto.
