ROAD REENFORCEMENT.

This invention relatesto improvements in metallic ire-enforcing means for concrete. road structures and thelike.- 1

The object of the present invention is to i provide animproved metallic net-workme enforcement which is adapted to be embedded in a concrete roadormtherlike structure-. This invention comprises a metal net-worku which is formed With diamond-shaped open-u ings and diagonals theretor all of which are formed from an integral sheet of metal which -isrfirst slit-and then-distended into such form;- The sidewalls of the diamond-- shaped-openings and the diagonals join at i the. ends-and sides of the openings to form channel-shaped bonds all 01 which liein substantially the same plane and some of which. open in-one direction While the others open in the opposite direction.. I

Fig-=1 is a perspective view-of a portion of my improved reenforcement; Figwflis'a sidevie'xv oi such a portion; andFig. 3 is an end View of such a portion, with some of the bonds shown in section.

The sidewalls or strands l of the diamond" 1 shapedopenings are clearly shown in the drawings as joining-the diag0na1s2so as to form the channel-shaped-bonds; the side.- walls 3 ot the bonds joining the strands of the diamond-shapedopenings,while the bottoms 4 of thechannel-shaped bonds join the diagonals. It is noted that-the side walls and bottomof the bondsare-substantially normal to each other,--or in other words the width of the side walls ofthe diamonds and thatof the diagonals extend "in planes substantially normal to each other. It Will be noted also that some of the bonds open in one: direction .Whi-leth others open in the opposite direction; as will be clear uponref erence to the bonds at the BRdS 'Of-tlIedlHw mond-shaped openings as compared with those at the sides thereof. All of the bonds lie in substantially the same plane, as clearly indicated.

It will be noted also that the diagonals extend out of the main plane of the net-work so as to form trusses and they aliord also a means of support for the reenforcement durin the process of pouring the concrete as wel as a means of anchoring the reenforcement in the completed road structure. The net-work reenforcement is adapted to rest upon-the flattened portions 5 of. the die; agonala; a I r The. nnproved net-work reenforcement. is.

formed either before or during ,the. distends on ingoperation. In anywevent, the side-walla or strands of the. diamond-shaped openings 1 are bent on lines which are substantially. normaltoth'e lines of bending of the diago-z nals; the particularmanner of bending ;the0'5 strands of the diamond-shaped openingsaand the diagonal strands preventing bucklingon crowding oi the metal-as thesheet is rdis tended into the net-Work form;- It will bet: understood that the diagonals extend length; wiseof the road. i

Thus such resistance to the distending :oporation isnot only obviated andthe opera-J tion accordingly 'facilitated, 1 but this. particular form of llet-WOI'k' I'GBIIfOI'CQIIIQIIt pos 7 sesses all possible rigidity and strength avith tl1e-increased reeni orcing factor due to the particular arrangement of the strands. l

Maximum a tensile strength is possessed" by.

this reenforcement and it ispractically proof so against -flexing stresses and strains in all" directions, sothat the danger of -the road creeping,buckling-sagging or cracking is; practically eliminated. The danger of the reenforeement giving or bending in a :direo- -ee tion normalto the road surface is-reduced;

to-a llll-lll'mlllll by-the diamond-strands.

standing on edge, so to speak;and likewiseany danger of lateral distortion =is obviatedespecially by the particulararrangementt ao of the diagonals; Thea diagonals might: bei 1 regarded; as-\half-dian1onds arranged at I to thwcomplete diamonds already? retested Ii Moreover, this reen'forcement, if so desired, may be so placed in a road structure that the upper faces 6 are flush with the top surface of the road, as indicated by the broken line 7, Fig. 2, representing the possible top surface location, with the resuit that an anti-skidding means is provided.

What is claimed is: 1. A metallic reenforcing structure comprising a diamond mesh, and strands forming diagonals of the diamonds, and extending out of the plane ofsaid diamonds so as to form trusses, the width of the walls of the diamonds and the width of the diagonals extending in directions substantially normal to each other.

2. A metallic reenforcing structure comprising a polygonal mesh, and strands vforming diagonals of said polygons, the width of the walls of said polygons and the width of said diagonals extending in directions substantially normal to each other.

8. A metallic reeniorcing structure comprising a polygonal mesh, and strands forming diagonals of said polygonals, the strands of said polygons and those forming the diagonals being joined in such a manner as to form channel-shaped bonds.

4. A metallic reenforcing structure comprising a polygonal mesh, and strands forming diagonals of said polygons, the strands of said polygons and those forming the diagonals being joined in such a manner as to form channel-shaped bonds, some of which open in one direction while others open in V the opposite direction.

5. A reenforcing structure comprising an integrally formed sheet metal polygonal mesh and diagonal strands therefor. the width of the walls of said polygons and the width of said diagonals extending in directions substantially normal to each other.

6. A reenforcing structure comprising an integrally formed sheet metal polygonal mesh and diagonal strands therefor, said diagonal strands and those forming the said polygons being joined in such a manner as to form channel-shaped bonds.

7. A metallic reenforcing structure comprising a diamond mesh, and strands forming diagonals of said diamonds, the strands of said diamonds and those forming said diagonals being joined in such a manner as to form channel-shaped bonds with the bonds at the opposite ends of a diamond opening in one direction and the bonds at the opposite sides of a diamond opening in the opposite direction.

8. A metallic reenforcing structure comprising a polygonal mesh, and strands forming diagonals of the polygons and extending out of the plane of said polygons so as to form trusses, the strands of said polygons and those forming said diagonals being joined in such a manner as to form channel-shaped bonds, the bottoms of which join the ends of the diagonals.

9. A metallic reenforcing structure comprising a polygonal mesh, and strands forming diagonals of the polygons and extending out of the plane of said polygons so as to form trusses, the strands of said polygons and those forming said diagonals being joined 'in such a manner as to form channel-shaped bonds, all of said bonds lying in substantially the same plane.

10. An expanded metal mesh comprising metal strips arranged in diamond mesh, the strips forming the sides of the diamond being arranged vertically, and connecting strips lengthwise ot' the diamonds arranged horizontally, the connecting portions forming open ended cups, the longitudinal connecting strips being bowed out of the plane of the mesh to add vertical depth'to the reenforcement.

11. An expanded metal mesh comprising metal strips arranged in diamond mesh, the strips forming the sides of the diamond being arranged vertically, and connecting strips lengthwise of the-diamonds arranged horizontally, the connecting portions forming open ended cups, the longitudinal connecting strips being bowed down below the plane of the mesh to add vertical depth to the reenforcement.

12. An expanded metal mesh comprising metal strips arranged in diamond mesh, the

strips forming the sides of the diamond, be ing arranged vertically, and connecting strips lengthwise otthe diamonds arranged horizontally, the connecting portions forming open-ended cups, the longitudinal connecting strips beingbowed down below the plane of the mesh to add vertical depth to the reenforcem'ent, all such cups in the same longitudinal and transverse lines being open in the same direction, but cups in adjacent longitudinal and transverse lines being open in the opposite direction.

In testimony whereof I hereby afiix my signature.
