CONCRETE-BLOCK WALL STRUCTURE.

Specification of Letters Patent.

A Patented Feb. 18, 1 919.

Application tiled August 16, 1917. Serial No. 186,617.

To all 'whom t may concern.'

Be it known that I, MYRoN M. METZINGER, a citizen of the United States of America, residing at Blair, in the county of Washington and State of Nebraska, have invented certain `new and useful Improvements in Concrete-Block Wall Structures, of which the following is a specification.

My invention relates to improvements in i closure, or standardized sizes of curved or circular walls for round inclosures.

Second, to supply a simple and effectual mortar bond for t'he bed and hczu'ling'joints of all general work with means adaptable and easily added for special requirements.

Third, to provide metal reinforcement of each unit or block and means for continuously connecting all thc units of reinforcement and blocks in a course of wall work, as well as to connect thc different superimposed courses of blocks and reinforcements in a wall, and,

Fourth, to facilitate the exclusion of inwardly penetrating moisture through the completed wall structure, as well as the thorough drying out of newly erected structures, and thereby avoid special exterior coatings on the completed structures.

I attain these objects by thc structural elements -illustrated in the accompanying drawings in which- FigureI 1 is a fragmental j'wrspcctive view of a building corner made of such a wall structure, showing the top and outside face of a portion of wall thlce courses high; Fig. 9 a vertical crosssect.ion of such a wall, taken on the broken line 2---2 of Fig. l; Fig. 3, a like section, taken on the broken line f'm-' of Fig, l', Fig. 1., a top or plan view of n course of blocks arranged to properly bond as the next course in height on the wall as shown in Fig. l; Fig. 5, a perspective view of the regular outside stretcher blocks for straight walls; Fig. o, a perspective view of thc outside angle or corner block for each cour-sc; Fig. i', a perspective view of the closer block for one side of an inside corner of every course; Fig. 8, is a fragment of a plan of curved wall, such as is used for silos and grain bins; Fig. 9, an enlarged plan of a curved wall stretcher block, disclosing the manner of metal reinforcement; Fig. 1t), a plan of a regular corner block, with its embedded reinforcing strip of sheet-metal correctly placed, Fig. l1, a perspective view of a bcnt end portion of the Hat bar or sheetinetal block-reinforcing strip and the vertical connecting or locking rod; Fig. 12, an enlarged perspective view of the smaller end of an outside. corner block; and Fig. 13, is an enlarged vertical section of a small block fragment, taken through one of the hernisphcrical mortar dowel pits. In all of these views similar reference numerals indicate similar parts of the structure.

Aside from such cut. blocks and closers as may be required to fit around wall openings and for adjusting lengths of walls. there are only threc'shaj'ies of blocks in this general structure; these arc shown in Figs. 5, and 7, and are of shapeI described as follows:

The stretchers for regular straight walls, lboth inside and outside faces, are of the same U-shapc, consisting of the straight body part 4f, having at its ends the rightai'igularly-disposed cross-bonding legs 5 and 5. For curved walls, silo or gram-bin structures, these stretchers arc modified only by curving the body portions i to correctly line the outer and inner wall faces as required, and adjusting the lengths of the bodies to bring the inncr and outer bonding legs 5 to coincide longitudinally for correct radial or cross bond, as shown in Fig. 8.

The outside corner blocks of a course each consist of an L-shaped body comprising a base limb 7 of length equal to the regular wall stretchcrs and a branch limb of onehalf that length. The projecting end of cach limb is provided with an inwardly` standing bondingdcg 8 to coincide with and be disposed between the bonding legs 1() and plain ends 11 of the adjoining closcrs in adjacent, subjaccnt and su )eriniposed courses,-see Figs. l and 4. These corner blocks are inverted, and reversed in position, for cach successively imposed course of blocks in the wall.

The inside corner closers or blocks are t, having on one end only the angular outwardl)` standing cross-bonding leg l0; the, opposite plain end 11 being of sutiieient length to lap and bond with the bonding legs 8 on the short limbs t3 of the outside eorner blocks of the adjacent courses above and below.

The hemispherical dowel pits 12 are madel in both bedding faees of all the blocks, disposed directly opposite. on opposite faces of the bloeit, so as to registerI and stand opposed in all opposed bleek faces on the same mortar bed or joint. To attain this agreenient of position of pits in the opposed hedding faces fo the blorlts in the 'all, the longitudinal rows of pits are disposed centrally of the bed faces of the bodies of the blocks amb-the cross rows eentrally of the bed fares of the emes-bonding legs; widths,l of legs and bodies being made equal and the pits coinposing eat-li pair of pits spared equally lengthwise ol eaeb leg and at the renter of the length of eaeh body part: and the pair of pits at. the longitudinal center ot' eaeh body bed register with the end or angle pits of the interbonding sltbjaeent and imposed stretel-ier blot-lts. It will be observetL by' noting Figs. 1 and l, that this arrangement disposes the pits` in pairs of cross-rows in the wall. a pair of eross ronvs at eat-h plaeeof eross-lnmding; also giving three longitudi nal rowsl of pits in the wall; the ventral one of which being kept in longitudinal aline ment eontrols the thickness of wall as well as the width of the hollow betaveen inner and outer fare blo'slts. These. pits heilig earetally lille/tl with a strong'naa'tar form an an rhoring ball.. as illustrated at 1'. in l `igs.-3 and lil, that for any ordinary requirement prevents any possible lateral or horizontal shift of super-imposed blocks or courses of bloelts ,in a` wall.

A further advantage of the above disposition of these bonding pits will be apparent. in the reinforeed blocks and inereased botuling means combined therewith for walls where greater resistance to very heavy strains are requiredf-ivhieh is set forth as follows: The. perforate reinforcing strips 16 are made of flat bar iron or heavy sheetmetal. eorners and to forni the bonding-leg reinfori-ing longues or legs 2L artl made b v bending the metal strip ohliquely llatwise upon itself as shown in Fig. 1l., When this metal reinforeement is bedded in the renter or core of the bloeks,as disclosed in lligs. 2, 3, S.) and 10, and the hloek has become induratedv` these angles are quite as rigid and strong as if stamped integrally angular from the sheet; metal. As shown in Fig. J the intermediate body portion lll is stamped out with the, required edgewise'curvature and the leg angles made as in other eases.

All of the-se reinforcing strips have the -lonall the required positions otA 'llho angles 18 to shape around the gitudinal rows of perte-rations 1T, as soon n. to give. the` strip a, more seeurtbed in the bleek. and te reduee to the minimum separa tion or division of the bloeit by the strip. The terminal or outer end perforation-- li" at the outer ends of the reinforcement legs` 21, are of size and are set coincident with and form part of the walls of the dowel pits 19 ir the bonding legsA These dowel pits extend vertu-ally elear through the legs and those in superimpostal eourses register with each other. as shown in l'" v Ji, Vertical bonding or dowel rods 3;. as shown in Fig, ll, of smaller diametri' to he flushed in around by mortar, may be seated in these rontinuous rertieal pits; or iwheri` the maximum oly strength and bond are required, riuso-fitting reriieal doive! rods are. seated therein. Matting this veitieal dowel--rml eontinuons. l have a strut-,ture reinforced and bonded against ail the .strains to which .etruetural walls are subjtrted.

lhe V-shaped vertieal grooves 2U. are diS- posed in the endsy ofthe bioelts and set; nearest to the fare thereof. ln the walls thev forni .square vertieal wells don a through the heading joint. see Figs. l and l., of snllieient size to readily tal; i a illing ol' mortar. This farilitates full flushing ofthe heading joints :with mortar and forms a heading joint look. preventing an); possible lateral movement of eithe` adjoining bloeit. lt serves as an anehorage for any rake-out, pointing of the lfathng joints and faeilitates attaining a heading joint that is air and watier tight:

In walls` laid of bloeks proportioned in sizes as shown. there are the large flue hollows 14. vertieally rontinuous` and the spaces between the reeurring eross-bonding legs. The inwardly extended ends of the legs are all spared a way from the, backs of the opposite. bleek bodies. to forni the narrow eonlmunieating slits 13 between the fines. By this means the new wall is easily dried. by leaving external openings at top and bottom of the wall hollow. To further render the wall impervious or weather proof, the entire inside surfaee of the body and bonding legs ofthe outside wall blocks` have a water proof eoatingtor layer 15.r This coupled with the use of a waterproof mortar in which the blocks arel laid excludes all weather moisture or dalnpnees from the inner face of the wall-`r and avoids the neces sity of any exterior wall treatment. that would mar the color or natural texture of the outer wall surface.

I claim:

1'. A conerete-bloek wall-strueture, comrisiug opposite faee walls' of like blocks aterally spaced to form a. hollow wall. inwardly projecting legs on the backs of the bloeks to interlap with the legs of bloc-ks in eourses below and above of the opposite, fare wall to bond the fano walls across the holmesses low,v reinforcing bars, disposed lengthwise Iof the Wall inthe bodies of the blocks, integral legs on the reinforcing bars standing angularly therefrom and disposed into the legs of the blocks and having. terminal eyes therein, and a central longitudinal row of vertical locking rods disposed through said interlappingblock legs and terminal eyes. 2.
