I I I tive View showing the interlocking relationship The construction which I have illustrated and of the units. described provides an interlockedreenforcement 55- My invention is shown in Fig. 1 in connection which resists stresses in every direction. This is apparent from an inspection of the drawings, wherein the end members or interlocking members are arranged in substantially parallel rows, while the cross members extend obliquely to the rows and thereby ofifer resistance to the method of piercing a wall by means of a Wedge shaped opening. A further advantage is that the entire reenforcement is interlocked so that in effect it constitutes a chain, which will add materially to the structural strength of the wall and prevent buckling in case of fire or explosion. A further valuable and practical advantage is the fact that the reenforcement may be fabricated with ordinary Welding equipment and that the arrangement and size of the parts may be selectively controlled and varied to suit any particular specification.
I claim: g 1. A reenforcement for a slab ofbuilding material, comprising a plurality of units each comprising end members and transverse members, some of the transverse members extending on one side of the plane of the end members and the remaining transverse members extending on the *opposite side of the plane, and all of the transverse members being rigidly connected to the end members. at spaced intervals.

A reenforcement for building construction, comprising a unit having a pair of end bars and. transverse bars welded thereto and in staggered relationship with reference to the plane of the end bars, the offset of the transverse members on one side of the plane being substantially equal to the ofiset of those on the opposite side of said plane. I
4. A reenforcement for a slab of building material, comprising a unit having a pair of end bars, a plurality of cross members rigidly connected to the end bars, and being disposed in staggered relationship thereon, the cross bars being substantially similarly, formed and the offset of those on one sideof the plane of the end bars being substantially equal to the offset of those on g 5. A reenforcing unit for a slab of buildingmaterial, comprising a unit having a pair of endbars, and crossv bars connected tov the end'bars at spaced intervals thereon, the cross bars being placed on opposite sidesv of the plane of the end members to forma diamond.
