4 claims.' (ci. 'zz-44) operation of hollow wall structures built from spaced cross tied blocks; to provide a hollow wall structure composed of inner `and outer spaced l blocks in which the'inner and"outer blocks are anchored with relationto each other by cross bars, and all or a portion of the blocks are tied t0 intermediate steel reinforcing bars by welding or the like: to provide a buildingblock which will form a pair of parallel spaced walls with a prac-` tically uninterrupted air space between them and co-extensive with the height and length of the walls; to provide a hollow wall structure having within it a reinforcing steel bar frame and in addition thereto sumcient space to receive wiring, conduits, water pipes, etc.; to provide a hollow wall structure lcomposed of spaced inner and outer l:blocks tied with relationto each other and `intermediate steel bars to form a substantially earthquake proof structure; and further to provide a hollow wall structure of the character described lwhich may be lthoroughly water and moisture proofed.

'I'heinvntion is shown by way of illustration 30 in the accompanying drawing, wherein 4 Fig. 1 is a perspective view of one 'of the wall blocks;

Fig. 2 is aplan view of a partially 'constructed y wall showing the manner in which the horizontal and vertical reinforcing rods are placed in the hollow wall space;

Fig. 3 is a sideelevation of a wall under erection;

Fig. 4 is a cross section of a foundation wall; 40

and Fig. 5 is a plan view of a corner block and an adjacent wall block.

` Referring to the drawing in detail and particularly lto Fig. 1, A indicates in general the 45.

type of building block employed for wally and foundation structures; The block consists of inner and outer blocks indicated at 2 and 3 respectively, formed from concrete or any other suitable material. In the casting of the blocks 50 they are spaced apart and are permanently tied q together by metallic members in the form of cross bars 4,beaded at the ends as indicated at 4a so .coated with any suitable material to prevent corrosion, and when reinforcing bars are Vwelded thereto as will hereinafter appear, redlead or a similar coating material should be applied.

The blocks when placed in a wall will be set up. A

in mortar in the usual way and should be stagv gered to break joints between courses. The cross or tie bars 4 connecting the inner and outer blocks must align vertically when theblocksare built into -a wall. this being important as vertically positioned reinforcing steel rods 4 are placedv in the 'hollow space formed between the blocks' and are welded thereto. 'Ihe cross bars 4 will also align horizontally and this is important as one or` more reinforcing steel bars 1 are placed on the cross bars'in a horizontal plane and welded either Ato the cross bars 4 or to the vertical bars or to. both. The number of vertical and horizontal bars -8 and 'l employed will depend entirely upon the.

final strength desired. Iiorl instances, thever- A .tical bars may be placed to engage every .second row of vertically aligning cross bars 4, as shown in Fig. 3, thereby'forming a connection or tie with each block; again, the vertical rods may engage each fourth row of cross rods. The same is true of the horizontal bars l, as these may be placed between every other course of blocks or Just as far apar-it as conditions may demand. In other words, every block in a wall may be tied` or welded to an intermediate steel bar frame or a certain percentage of them maybe so Joined anda substantiallyfearthquake proof structure is thus insured.

To insure vertical and horizontal alignment of the cross bars 4 when the Iblocks are set up in 'a wall, let it be assumed that the blocks are 18 inches long and 4 inches high. If that is the case, the cross rods connecting the inner and outer blocks will be placed on a center line be tween the upperl and lower faces of the blocks, and 4 inches in from each end; by so placing them, vertical' and horizontal alignment is in sured, particularly when thelblocks are -stag-v gered between courses to break joints.

For the construction of Icorners whereftwo walls meet, corner blocks of the type shown in Fig. '5 are employed, and break or staggered joints are also here insured by mer'ely reversing every otherV corner block.. To assist in properly aligning or positioning the blocks in each course, false `rake Joints I0 may be formed in the outer face of each block. This has an addedvadvantage in breaking up the surface, thereby avoiding thel unpleasant I, as to become firmly anchored in the concrete when it sets. The barsl may be galvanized or effect of long rectangular shaped blocks. The blocks may be water and moisture proofed on their inner adjacent faces eitheil before or after placement in a wall. This is also important as it leaves the main inner and outer faces of a completed wall free to receive any finish or treatment desired.

Sufllee it to sayA that a hollow block wall with an intermediately reinforcing steel frame, to which the blocks are tied, is secured; a moisture and water proof structure is insured; the insulating advantages of an intermediate air space together with space for wiring, piping, etc.. are obtained: and above all, a structureY is provided which can be erected at a minimum cost.

The blocks are intended not only for wall structures but also for solid foundation walls. When so employed, a footing ii of concrete is first poured, on top of which the blocks are placed just as in a wall structure, two to three or more courses being employed depending upon the height of the foundation. Vertical and horizontal reinforcing rods i2 and M- are placed between the blocks and into the footing, and the hollow space is then filled with concrete to make a solid foundation. A foundation of this character may be employed for ordinary wooden frame .buildings or as a foundation for a reinforced hollow' wall structure such as here described. It is cheaper than 'an ordinary foundation as the lumber and carpenter labor required in connection with the building of forms vto receive the concrete is entirely eliminated.

While this and other features of the invention have been more or less specifically described and 3. In a hollow wall structure of the character' described, pairs of opposed wall forming blocks, cross bars embedded in and connectingeach pair of blocks, said pairs of blocks being spaced apart to form a hollow wall space, said cross rods aligning vertically and horizontally in the wall, and a plurality of vertically and horizontally disposed steel bars disposed within the wall space and welded to the cross bars to form a rigidy framework.

' 4. In an earthquake-resistant hollow wall structure, the combination of a plurality of spaced outer and inner blocks joined by cross rods embedded therein, a corner block comprising an outer block formed with a long section and a short 1 section normal thereto, an inner -block extend-v ing parallel to said long section, an offset portion substantially uniform in thickness with saidinner block formed integrally therewith and disposed parallel to said outer block long section and closer thereto than the remainder of said inner block, an anchor bar normally joining said
