9 Claims. 1

This invention relates to improvements in building blocks and the methods of making and installing the same, and more particularly to building blocks of the character desirable for the erection of residences, commercial buildings, garages, and the like, although the invention may have other uses and purposes as will be apparent to one skilled in the art.

I am aware that in the past many and various types of building blocks have been provided, both prefabricated and otherwise. These formerly known blocks, however, were highly objectionable in that they were undesirably expensive to manufacture and install, requiring an excessive amount of labor of a highly skilled variety to make the proper calking, put it in the proper expansion joints, furring, load supports, accommodate conduits and piping, provide adequate insulation, etc. Further, blocks of the character heretofore used did not provide a finished interior of the character desirable in a residence. The only exception to that statement were the so-called glass blocks, and such blocks are clearly nonload supporting and consequently could only be used in panels with load bearing members disposed therearound, and the difficulty incurred in effecting proper calking, uniting the blocks one with the other, and providing means to compensate for expansion was tremendous.

With the foregoing in mind, it is an important object of the instant invention to provide a structural building block made of metal.

Another object of the invention is the provision of a structural building block made of a light-weight metal such as an aluminum alloy and which is designed to carry the structural load of the building as well as the normal live load, without the use of stringers, joists, pillars, columns, and similar load bearing devices.

Another object of the invention resides in the provision of a structural building block which may be very economically produced and installed, and which may comprise merely a simple metallic stamping, folded or shaped, and spot welded or equivalently secured in that shape.

Also a feature of the instant invention resides in the provision of a metallic building block of such construction that adjacent blocks are locked or welded together when laid, without the use of any mortar joints, resulting in extremely fast and economical laying of the blocks.

Also a feature of the invention resides in the provision of extremely light weight metallic building blocks which may be made" of substantially any desirable shape.

The instant invention also seeks the provision of a metallic building block made of light metal, such as an aluminum alloy, possessing a high degree of reflectivity on its outer surface, and which may if so desired be clad or otherwise treated so as to provide a variety of external colors.

Another object of the invention resides in the provision of metallic building blocks made hollow so as to accommodate substantially any type of insulation or acoustic material therein, and which in view of the fact that the blocks themselves carry the building load, both structural and live, a greater cubical interior content results from fixed outside dimensions by virtue of the fact that the building wall need only be the thickness of the blocks themselves and thus is a comparatively thin wall.

Still another feature of the invention is the provision of metallic building blocks in which no provision, either by way of material or special joints, need be made for expansion, in view of the fact that the entire structure expands the same throughout.

Another advantage of the instant invention resides in the fact that the metallic blocks are very easily calked or sealed against the weather while being laid and without any special attention to the calking process, and the joining of the blocks one with the other results in a compressing and fixing of the calking.

Still another advantage of the instant invention resides in the fact that a light foundation may be used for a building by virtue of the fact that the blocks themselves are of extremely light structure.

Still a further advantage of the instant invention is embodied in the block construction, the blocks being prefabricated to accommodate pipes, wiring conduits, and the like.

It is also an object of this invention to provide hollow metallic building blocks which support the building load, and if any reinforcing is needed, that reinforcing may be provided within the blocks themselves, and without interfering with the adequate insulation of the blocks containing the reinforcing means.

Also an object of the invention is the provision of metallic building blocks with which any interior finish may be associated, the interior finish preferably being in the form of inserts held by means integral with the blocks, whereby the interior of a building may be changed at will without requiring skilled labor to effect the change,

or if desired, the interior may be made of a substantially permanent character.

One distinctive advantage of the instant invention is the fact that when the blocks are properly laid, provided with insulation therein, and the interior inserts mounted, the entire wall construction is finished including both outside and inside finish.

Another distinctive advantage of this invention resides in the 'factithat screened openings, glazed openings, and the like may be provided wherever needed and installed along with the laying of the blocks themselves andin substantially the same manner as the blocks are laid, the screened or glazed closures for such openings being prefabricated in similar manner to the blocks themselves.

It is a further object of the instant invention to provide a novel method of making and installing metallic building blocks.

While some of the salient features, characteristics and advantages of the instant invention have been above pointed out, others will become apparent fromthe disclosures, taken in conjunction .with the accompanying drawings, in which:

. Figure 11 isan isometric View of a type of laminated insulation or acoustic material that may "be used within the blocks; and

Figure 12 isan isometric view of a type of inside finish insert which may be utilized in connection with the blocks.

As shown on the drawings:

With the illustrated embodiment of the instant "invention, referring to Figure 1, there is shown a wall section, generally-indicated by numeral l, and made up of a plurality of blocks 2. In this particular-wall section, 'a window arrangement, generally indicated bythe numeral 3, is provided, .this window arrangement beingset in position in .is preferably made up from substantially the same manner as the blocks themselves are set in position. By virtue of the staggered arrangement of the blocks in adjacent courses a plurality of substantially half-size blocks, as indicated at 4, will be necessary, the number depending upon the size of the window opening. These half-size blocks are of the same general construction as the full-size blocks and are only used to evenly rfinishoff the edge of a wall adjacent a .window-or door opening, or in some instances, at a corner of the building.

With reference more particularly to Figures 2, .3 and Lit-may be seen that an individual block a single blank shown in the flat in Figure 4. This blank may be stamped or punched from a sheet of metal, such as aluminumualloy and is so shaped as to define a panel 5 which provides the outside surface of the block. This panel has a projection 6 on each of three sides thereof, which projections may extend from-end to-end-ofthe respective .side of the panel if so desired. In other words, these ,projec-tions are not fixed as to size,'but -may be .as large as deemed most expedient. Each projection isprovidedwitha groove 1 embossed therein,

the closed side of the groove formation being visible in the showing Figure 4.

One side of the. outsidepanel 5-is integral with :an elongated band-like portion, generally indicated by numeralii. Thisportion may be provided with .a plurality of scor-e lines 9, shown dotted I'm-Figure def ning-lines oi .iold for the band'portion. This band portion is also provided with .a pair of grooves Iii-til spaced from each other and-extending the :entire length of the band, the groove .iormations d ll-l0 being just sl-ightlyless i-n size than the :aforesaid groove formation 1 onthe projections or side tabs 6 .of the back panel. The'bandzmay also be provided at spaced intervals withsuitable apertures il, these apertures providing openings for the :niltimate installation :of pipes or conduits. In order "to define asupportniorithe inside finish insert, the'band is also provided with numerous tongues l2 struckfrom -the body of the band and bent at r-ight amglestheretogthere being two of these tongues toreachsec-tion of the band in the illustrated showing, although any desired number and shape of such tongues may be utilized.

In forming one of the blocks 2"from the blank of Figure 4, the back panel 5 is'fold'ed upwardly, the side tabs 6 are turned inwardly, and the band is bent substantially at :right angles along each :of the lines of fold "'9 and thus wrapped around thesideta'bst. After the, folding operation has "been completed, the band is spot welded .or

equivalently secured to .each of the side .tabs 6. One .endof the band maybe inturned as indicated .at.i3 in lFigur.es.2, .3 and .4, and the opposite end portion of the band overlies-the .in-turned .part l3 and maybe.spotavelded-thereto if so desired. It=willbemotedthat one portion of the band, that is one section, is longerthan the others, and

projects beyond the box [construction proper as indicated at 1-4.. When-the :bloc-k-s are disposed side by side along a :course, portion "M :of one block overlies the'upperpart'ofithe adjacent 7 block, and mayirbe spot weldedftothe next adjacent block initiate. region oi fthe overlap. At the .same time, adjacent sidewalls of-adj acent "blocks mray 'be spotted either one or'a plurality of times to each other so thateach block-is effectively united to blocks on each-"side thereof, and blocks above and below, so that an entire wall is substantially an integral structure.

The spot welding may be accomplished, it being recalled that the box-like blocks are open on the inside, by use of a suitable implement that operates in the character of a pair of pliers and each time the points are pressed together a weld occurs. Thus, the positioning of the blocks and the welding of them together may be done very expeditiously and with a minimum amount of time and labor.

As indicated in Figure 8, a pair of superposed blocks may be spotted twice in line as indicated at 15. With blocks laid in courses as indicated in Figure 1, and each block spot welded to all blocks adjacent to it, it will be apparent that the blocks themselves will carry the structural as well as the normal or ordinary residential live loads and no addition load bearing structure is necessary.

In the event it is desired to strengthen the blocks for any purpose at certain points, it is a simple expedient to lay a staggered vertical course of blocks of the character seen in Figures 6 and '7. In these figures, blocks are shown provided with internal reinforcing in the form of a cross frame l6 having the ends of each leg of the cross reversely bent and spot welded or equivalently secured to the adjacent side wall of the block as indicated at [1. With reference to Figure '7, it will be seen that the cross arrangement 16 does not extend the full width of the block and so allows ample room for the positioning of the interior finish insert. The reinforcing I6 is preferably made with the same material as the block itself so that it will not only have the same strength as the block, but expand in accordance with the block so that no provision need be made for reinforcing expansion.

With reinforcing in the block of the character seen in Figures 6 and '7, insulation I8 may be packed in the triangular spaces defined by the reinforcing. This insulation may be of substantially any desirable or suitable material. A satisfactory insulation is crumpled aluminum foil which not only affords a very high degree of heat insulation, but also is extremely light in weight, in keeping with the entire structure formed by the blocks.

Of course, it is desirable to seal or calk the cracks between the blocks when they are laid in their courses. With the present invention, no particular and special attention is essential in order to provide proper calking. The calking may be provided in part automatically, and in part by a very simple operation. For example, as indicated in Figure 3, the vertical calking may be provided upon the blocks. That is, the grooves extending over one end portion of a block may have attached thereto in any desired manner, such as by cementing, a suitable calking I 9 which may be in the form of substantially round strings or cords of calking material. The calking proper may be of any suitable material, preferably some material that is easily handled. Satisfactory material may be strings of oakum, or a cord of rubber or rubber composition would be satisfactory. The calking is substantially sealed in position when the blocks are properly laid, and so that calking would have extremely long life, not being subject to the elements except to a relatively minor extent. In connection with the horizontal courses, the grooves ID in the upper faces of the blocks, which grooves will be continuous throughout the entire course of the blocks substantially twice the size of the grooves so that it will fill up the corresponding groove in the next adjacent block. When the blocks are laid into position, as seen in Figure 8, the calking is compressed between the two blocks, and substantially sealed in place. The holding of the calking results from the spot welding as indicated at l5, and the calking can never leave its position unless the blocks are ripped apart. With the vertical calking l9 already attached to one end of a block, that calking is automatically placed in position when the next adjacent block in the horizontal course is laid.

The calking also serves another function, in that it establishes a slight cushioning take-up between the blocks so as to compensate for the projecting portion [4 on a block. This projecting portion when overlying the next adjacent block provides an added thickness of material, and this added thickness of material is compensated for by the give of the calking, so that the courses of the blocks will still be substantially level.

In the event the blocks do not have the reinforcing !6 therein, other types of insulation may be used, such for example, as illustrated in Figure 11. This insulation, designated 2!, may be of the block type such as rock wool, Celotex, asbestos compound, or other suitable material. After the metallic blocks have been laid in position, insulation of the character of 2| may be inserted in the blocks, as also shown in Figure 5. Obviously, the insulation blocks 2i may be properly shaped to pass by the lugs l2 in the blocks, such shaping depending upon the thickness of the insulation. By way of example, it may be said that the metallic blocks themselves may be made in substantially any desirable size, such as, six, eight, or twelve inches square, and these blocks may satisfactorily be used with a thickness of four inches. In all cases it would not be necessary to have the insulation of a depth equivalent to the entire thickness of the block With the exception of the inside finish insert, but in many instances the insulation need only occupy half the thickness of the block or perhaps a lesser amount.

As to the inside finish of the building, and by inside finish is meant the ultimate interior decoration of the room, it is a simple expedient to use the building blocks as a holder for that finish. In the illustrated embodiment of the invention, a block 22, shown in Figure 12, may be pressed into the box-like metallic block against the lugs l2, as seen in Figures 7 and 8. This insert 22 may be of any desirable material such as glass, clay, wood, rubber composition, cork, linoleum, etc., and may have substantially any desired interior finish and color. Obviously with such an arrangement, it is a simple expedient to acquire color combinations in the interior of the room and provide borders, if so desired, with no more labor than required to provide an ordinary plain interior finish. If so desired, the inserts 22 may be cemented into position in the structural block, but in most cases that operation will not be necessary.

With reference to Figure 8, it will be noted that the inside edges of the structural blocks themselves may be skived or curved as indicated at 23, and the edge. portions of the inserts .22 may acrea e also. be curved asv indicated. at 241 to add to the attractiveness of the interior finish. by' providing smooth joints between the insert. panels.

Itis also a. simple expedient to. provide windows, and equivalent openings; inconnection with the instant invention, the provision or such: openings requiring mo -added or. special: attention on the part of the operator: laying the blocks. By virtue of; the staggered courses, as stated: above, it. would be necessary to use half. blocks 4' in atternate courses adjacent. such openings, as seen in Figure 1. Such half blocks are; provided in substantially the same: form as the regular size blocks with the soleexception of size and are handled in thesame way. With reterence more particularly to Figurev 5, it will be. seen that. a window block generally indicated bynumeral 25 comprises merely the bands portion of a. regular block without a back panel 5; The band is provided' with the grooves to. hold? the calking, and the inside ofthe band, preferably inside the groove formations is a pair of spaced panes-of glass, plastic, or other substantially transparent material. The spacing, between the panes. 2'6 iunctions as a dead air insulation space sothat even. the window openings may be properly insulated. as well as the solid portion of the structure. In. the illustrated embodiment, the window opening blocks are'made of thev same: size as. the regular structural blocks, but it will be appreciated that if desired the window openings may be in the form of a.- singleblock of the: size. of the entire opening, no added: diflioulty' being, en.- countered: in installing thesame. In the event itv is desired to have apermanent and definite opening through the wall, for purposes of draught, ventilation, and the like, it. is a simple. expedient to substitute screen for the glazing in the window blocks. In most cases, it will not be desirable to open a window, and this is. especially true'i'f the inside of the structure is air conditioned. However, the glazing: may be mounted upon a hinge mechanism if sodesired and. still. provide adequate insulation and: permit the free: opening of the window.

In Figure 9, I have illustrated what may be termed a corner block 21;. thewblock being constructed in substantially the. same: manner as above described in connection. with Figure 4, but

given an arcuate shape so that if. a. rounded corner on the building is desired, the corner blocks may be laid insubstantially the same manner as theside blocks.

, Again, in Figure 10, I have shown; what might be termed a radial or keystone. block, if suchmay be desired in any portion of. the structure.

The examples of Figures 9 and;- 10 are not in any manner conclusive, but are merely-indicative of the. fact that the blocks: may be madeirr sub.- stantially any desirable shape to fit" in with the architectural design ofthei building.

In constructing a building withblocks embody ingv principles of the. instant invention, only a light foundation need be provided in comparison with foundations used for buildings; constructed with materials heretoforeknown. This is be.- cause the blocks themselves, if. made of an ale..- minum alloy or equivalently light metal, have little dead weight. so, that the: structural load of the building is considerably. less than; is the case with other materials. After a foundatiorr has been provided, it-is a simple expedient. to lay the courses of blocks, and spot weldz adjacent blocks to each other at oneor. more points. In addition to. the spotting oi thesidewalls oradiacentblocks 8 together; the overhang l t of one block establishes a direct bond with an adjacent. block. When the next course-ofblocksis-l'aid in staggered relationship and; on top of the first course, after the postti'oning of the calki ng elements 20-211, it is a simple expedient to spot the upper course to the lower course sothat in effect theenti're wall of the building is one integral load: supporting lightweight structure; If for any reason: additional load: bearing power is desired in certainportions of the structure, it is a simple expedient to incorporate reinforced blocks of the character seen in Figures 6 and '7. No change in the methodof laying the blocks is: required, and the only additional care necessary being that to place the reinforced blocks in the proper location. After the blocks have been laid, insulation may readily be added by merely filling in the box-like blocks from the inside of the structures. After the insulation has been so provided, the interior finish,

inserts may be pressed into the inside opening of each block. When that is done, not only is the structure complete, but the interior decoration of the wall is also provided at the same time and with relatively little cost. Such interior decoration may be semi-permanent incharacter, or may be changed at will even by an unskilled occupant of the building. It issimplynecessary, in effecting such a change, to pry out the inserts already there, and press in new inserts having the desired finish thereon.

The blocks themselves may be simple stampings, or may be die drawn, or made in an equivalently-economical manner. 'I-heblocks are preferably completed at the manufacturing plant and shipped to each job ready for installation. It will be noted that with blocks of this character the shipping load is light and a car may bef'llled to its volumetric capacity so as to take advantage of all space. Due to the shape of the blocks, their loading is simple and no specialpacking is reqnired.

In the use of the instant invention, it will be especially noted that no particular pains need be taken or no realspecial attention given to the matter of. calking. It is a simple expedient to-lay the string-like elements 20-20 upon each course of blocks when that course is completed, and as above explained, the vertical ca-lking is taken care of automatically provided eachblock has calking secured thereto at one end thereof. Itshould also beespeciall'y noted that no regard need be given expansion. No special provis-ion for expansion need be made either by Way of material, special joints, or in any other fashion, since all parts of the structure expand alike.

Further, it will be especially noted that the blocks are prefabricated for piping and conduits, and that allsuch wiring and plumbing installations maybe effected ina ready mannerprior to the placing ofthe insulation. desired, heating elements may be installed directly in the wall, and arow of the-blocks provided with open-work interior finish inserts to permit egress for the heat. Convenience outlets, wall brackets, etc. may be provided directly upon an interior finish insert so that no special attention need be given the-placing of'suchitems;

As to the external: appearance, it will be noted that if'the blocks are made of an aluminum alloy, or equivalently bright" metal; the reflectivity will be extremely high, and yet the-structure will have a. very pleasing appearance. It so desired, the metal of the blocks may be clad; on. the outer face so as to provide any desired; color scheme;

The economy both of manufacture and installation of the blocks and the resultant economy of the entire building structure is an item of major importance, to say nothing of the fact that greater cubical content for fixed outside dimensions is obtained. In addition, it may Well be mentioned that the holding of the entire interior finish by clips or lugs struck from the blocks themselves adds to the economy of the structure, and the interior of the building may be soundproofed or otherwise acoustically treated merely by the use of interior inserts having that characteristic.

It will, of course, be understood that various details of construction may be varied through a wide range without departing from the principles of this invention and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
