REENFORCED CONCRETE ROAD CONSTRUCTION Filed Nov. 29, 1926 Patented Sept. 24, 1935 UNITED STATES PATENT O E naauroncan ooNcna'ra norm CONSTRUCTION Albert 0. Fischer, Chicago, m, assignor to The Philip Carey Manufacturing 00111911 7.; corporation of Ohio 10 Claims. (Cl. 94- 18) My invention relates in general to concrete or the like road construction, and has particular reference to the reenforcement of the concrete in such a construction, as well as the provision for contraction joints.

The primary object of my invention is to comblue the reenforcing structure and the contraction joint structure in such a way that one will cooperate with the other to not only facilitate building of the roadway, but also to realize the best results from materials used.

In the accompanying drawing I have illustrated the salient features of the invention, and in which Figure 1 is a perspective view showing a combined arrangement between a separating stripLfor contraction purposes and the reenforcingrods;

Figure 2 is a similar view showing mo dified form of separating strip. I

Figure 3 is a perspective view-.of-- aaportion of the reenforcing grill combined with a separating strip. v;

Figure 4 is a plan view showing the separating strip combined with the reenforcing'grill and in combination with reenforcing rods.

Figure 5 is a detailed view in plan showing the connection between the grill and the supports for the reinforcing rods, and Y Figure 6 is a detailed view in verticalsection showing the separating strip andthe grill as incorporated in the concrete structure of the'roadway.

Referring now to the drawing in detail, I pro- -vide a separating strip 5, preferably of metal,

- which isvertically supported by and welded to the reenforcing bars 6. Or else in lieu of the strip 5 I may employ a tongue and'groove structure I, which is in the form of a strip, having upper and lower flatportions 8 and 9, yoked together by an intermediate tongue and groove Ill. In this structure the reenforcing rod iiwould project thru the intermediate tongue and groove. Either of these forms may be used in combination with the grill work II," by providing'metal cuplike sockets l2 and welding the same to the grill so that the ends of the reenforci'ngrods 6 are received therein as a means of supporting and connecting the separating strip and the rods to the grill. To compensate for expansion and contracweakness, so that upon expansion and contraction of the concrete any cracks tending to occur will be in alignment with the separating strip.

When the tongue and groove separating strip is used the tongue and groove structure of the 5 same will interlock the concrete together on o'ppositesides of the strip, so that when the cracks occur in alignment with the separating strip the tongue and groove will prevent the divided sections thus formed from riding one upon the other. 10

As a modified form of the same principle the separating strip 5 may be used without the reenforcing rods 6, in which event it would be welded directly to the grill work II, as shown in Figure 3.

I claim: I

1. In a concrete road, sections oi. grill work embedded horizontally in the concrete and said grill sections being yoked together by reenforcing bars, and a separating strip having its bottom 20 edge resting on said bars.

2. In a concrete road, sections of grill work embedded horizontally in the concrete and said grill sections being yoked together by reenforcing bars, and a separating strip vertically supported by said bars entirely above the grill work.

3. In a concrete road, sections of grill work embedded horizontally in the concrete, sockets projecting from the confronting ends of the grill work sections, reenforcing bars inserted in said sockets and brid ing the space between the grill sections, and a separating strip supported by said bars substantially intermediate the ends thereof.

4. In a concreteproad, sections of grill work embedded horizontallyin the concrete, .sockets projecting from the confronting ends of the grill work sections, reenforcing bars inserted in said sockets and bridging the space between the grill sections, and a separating strip supported by said bars substantially intermediate the ends thereof, 40 the inserted ends of said bars terminating short of the attached ends of the sockets and leaving spaces in the sockets in which the rods may slide upon expansion and contraction of the concrete.

5. In a concrete road, sections of grill work embedded horizontally in the concrete, sockets projecting from the confronting ends of the grill work sections, reenforcing bars inserted in said sockets and bridging the space between the grill sections, and a separating strip supported by said bars substantially intermediate the ends thereof, the inserted ends of said bars terminating short of the attached ends of the sockets and leaving spaces in the sockets, said spaces being filled with compressible material, and the rods being adapted to slide in the sockets against said compressible material substantially as/and for the purpose 4 described.

embedded horizontally in the concrete. attached to the grill sections, and a Join eiining strip secured in place entirely above said rods.

7. A concrete surfacing structure having reenforcement sections embedded therein, and a joint defining strip extending over said reeni'orcement, the reeniorcement including rods for holding the strip in place entirely above said reeniorcement.

8. A concrete surfacing structure reentorcement comprising grill sections, and a joint defining strip extending thereover, said reeniorcement including rods for holding the strip in place entirely above said reentorcement.

9. Aconcrete surfacing structure having Joint means and reeniorcement grill sections embedded therein, said reenter-cement including rods attached to said grill sections and engaging said Joint means for holding same in position entirely above said reentorcement.

10. In a concrete road, grill sections embedded horizontally in the concrete, reeni'orclng bars inrposed between the grill sections, a separating s p supported by the grill sections, and a compression and expansion means associated with the reeniorcing bars.
