Application filed February 18, 1919. Serial No. 277,791.

To all whom it may concern:

Be it known that I, Jerome W. "WnLoH, a citizen of the United States, residing at Sergeant Blufi, in the county of Woodbury and State of Iowa, have invented certain new and useful Improvements in Concrete Structures Having Waterproofing Reln forcements, of which the following is a specification.

My invention relates to new and useful improvements in reinforced concrete structures, the primary ob'ect of my invention being the provision 0 a waterproofing reinforcement which may be employed in constructing concrete blocks for building puroses or which may be employed in the building of monolithic concrete walls.

A still further object of my invention is the provision of a metallic reinforcement in the nature of a partition wall which may be spaced any desired extent from the weather face of the block or wall in which it is incorporated and which carries a plurality of reinforcing anchoring elements which are embedded in the concrete.

In concrete blocks, the partition wall or main body of the reinforcing element @X- tends throughout the length and breadth of the block and at its edges is adapted for locking engagement with the reinforcing elements of adjacent blocks so that in a finished structure a thin metallic wall is in effect provided between an inner and outer wall, although the parts are so firmly united and braced that there can be no separation between them.

Another object which I have in View is the provision of novel means for locking the ends of adjacent blocks together, and a novel means for holding the blocks of one course in a wall construction from movement with respect to the blocks of another course.

Another object which I have in view is the provision of means for insuring proper positioning of the reinforcing elements during construction of the wall and to provide additional bracing devices for the wall.

With these and other objects in View, my invention will be more fully described, illustrated in the accompanying drawings, and then specifically pointed out in the claims which are attached to and form a part of this specification.

My improved metallic reinforcement includes a rectangular body 10 of sheet metal of any desired length, breadth and thickness, the length and breadth of the sheet being substantially that of the block in which it is to be used. Secured along the ends of the body member and against both sides thereof are strips of sheet metal 11 which project beyond the ends of the body and are bent outwardly away from each other and then rebent toward each other to provide books 12. As best shown in Fig. 2, the hooks are opposed to each other with their bills spaced somewhat apart. Secured against opposite faces of the body 10 along each side edge are strips 13 which, at their ends, abut against the inner edges of the strips 11 and which project somewhat beyond the edges of the body to provide channels '14s, as shown in Figs. 3 and 4:. The end strips 11 are formed intermediate their widths with relatively wide slots 15 running parallel with the ends of the body. Secured over the end strips 11 are outer end strips 16 which terminate at their ends flush with the outer edges of the side strips 13 and which are formed with relatively narrow slots 17 enlarged at one end to provide an opening 18 e ual in Width to the slots 1 5. These narrow s ots 17, together with their continuations 18, are equal in length to the slots 15 and serve as anchoring seats for a number of reinforcing elements 19. Each of these reinforcing elements includes a body of sheet metal having its outer end bifurcated and the arms thus formed bent laterally in opposite directions to provide anchoring members 20, as clearly shown in Flgs. 1 and 2 and having its inner end bent at a right angle, as shown in Fig. 2. Secured to the body portion of these strips 19, ad a cent the ends 21, are strips 22 which have their free ends bent at right angles, as shown at 23 to lie in the plane of the terminals 21 of the strips. The portions 21 and 23 thereby form seating heads which may be passed through the openings 18 and into the slots 15, the portions connecting these heads with the remainder of the reinforcing element being slidable in the slots 17. By this means, a number of the reinforcing elements 19 may be applied to the ends of the main reinforcing element or structure 10 at either side.

Extending longitudinally of the body 10 and along both sides and in parallel spaced relation to the side strips 13 are supporting strips of sheet metal 24 which, at intervals, are out struck to provide pockets 25 capable of receiving the terminals 26 of substantially Z-shaped reinforcing elements 27. Each of these elements is in the form of a strip of sheet metal having its end portions bent at right angles to its intermediate portion. These reinforcing elements 27 are employed only along the upper part of the body 10 and, of course, have their ends hooked downwardly into the pockets and their other ends directed upwardly. Somewhat similar reinforcing elements 28 are provided for the lower portion of the body in which the outer ends are bent parallel with the inner ends so that the outer ends may extend downwardly when the inner ends engage in the pockets. Obviously, any number of pockets may be provided and a number of reinforcing elements 27 and 28 employed and the space at which they are positioned may be altered at will.

Extending longitudinally of the body at each side and substantially midway of its height, are strips 29 of corrugated sheet metal, the corrugations of which, together with the body 10, provide a series of pockets 30. U-shaped reinforcing loops 31, of wire or equivalent material, have their endportions bent into parallel spaced relation in a plane at right angles to the body portion to engage in these pockets 30 so that the intermediate or U-shaped portions of the devices 31 will project at right angles to the main body 10. Any desired number of these bracing members 31 may be employed at each side of the body 10 but preferably they are so arranged as to slightly overlap each other, as shown in Figs. 1 and 2 of the drawings.

The above described structure constitutes the reinforcing element or member proper of a concrete block and in making the block such reinforcing member is embedded between the front and back walls of the block with which it is coextensive. The reinforcing structure is preferably embedded in the block so that its body is located from one-third to one-half the thickness of the block from the front or weather face of the block, although this location is not absolutely essential. The block is of such size that the edges of the side strips 13 are flush with the upper and lower faces of the block, while the hooks 12 project beyond the ends of the block.

In building a wall from the above described reinforced concrete blocks, the blocks to make up any given course are placed end to end in the usual manner which brings the hooks at the end of one block against those at the end of an adjacent block, as clearly shown in Fig. 6 of the drawings. U-shaped anchoring strips 32 of sheet metal are then applied in the manner shown in Fig. 6, each locking one of the hooks of one block to the abutting hook of the next block and the two together holding each other against displacement. These locking members 32 are preferably embedded in a liquid metal cement which will later set to form a waterproof joint and any suitable form of cement or mortar 33 may be employed to close the remainder of the joint between the blocks. As a means for holding the blocks of one course against lateral movement with respect to the blocks of adjacent courses and also as a means for providing waterproof horizontal joints between courses, I employ looking strips 34 of sheet metal which seat in the alined channels 14 along the top and bottom edges of the blocks formed between the strips 13 and which are set in the same metal cement. A thin layer 35 of cement or mortar is interposed between the courses of blocks.

From the foregoing description, it will be apparent that with any wall constructed with such reinforced concrete blocks it will be impossible for water or moisture to pass through the block asan absolutely water tight metallic partition wall coextensive with the concrete wall is formed by the re inforcing structures and water tight joints between them. At the same time, the various anchoring devices or reinforcin elements 19, 27, 28 and 30 being embed ed in the concrete, positively bind all the parts together so that the block has greater tensile strength than any concrete block of corresponding dimensions not having the metallic reinforcement.

In Figs. 8 to 10 inclusive, I have illustrated a metallic reinforcement to be employed in the construction of monolithic concrete walls, This reinforcement is identical with that previously described, except for certain additional elements. Anchoring plates 36 are riveted or otherwise Secured against opposite sides of the body 10 at suitable points, such as at diametrically opposite portions of the central part of the body, as shown in Fig. 8, and have threaded sockets to receive rod or pipe sections 37 which extend at right angles to the body 10 and which, at their ends, are connected by unions 38 with vertical rod or pipe sections 39. These pipe sections, secured to the body as described, greatly increase the strength of the wall, and they may be longer or shorter according to the thickness of the wall. In addition to these supplemental anchoring members I provide centering fingers to in the form of strips of sheet metal secured to opposite sides of the lower edge of the body 10 and projecting beyond such edge having pointed terminals 41. The free ends of these centering fingers are adapted to straddle the upper edge of a subjacent body section to insure bringing the channels 14: of such sections into alinement with each other to properly seat the anchoring strips 34:. Of course, in building the wall, the reinforcing elements are assembled and connected with each other as the work of building the wall progresses, the various anchoring members being applied in each instance just prior to the application of that layer of concrete which will embed them.

Although I have illustrated and described my invention in all its details of construction, it will of course be understood that I do not limit myself to such details but reserve the right to make changes, within the scope of the appended claims, without in the slightest degree departing from the spirit of my invention.
