`s claims. (orizz- 66) l VOur inventionrelates to oor constructions and refers particularly to floor constructions composed of hollow re `proof blocks such. as those which are made from clay or concrete.

The value of hollow lire proof blocks, and particularlyconcrete blocks,` is well known and their general adoption is proof of their utility.

Among the desirable features incident vto :floor constructions composed of concrete, and similar, hollow blocks are the adaptability of .the blocks to spans and lengthspf diierent dimensions,

their ease `of' incorporation and construction into l the linished iiooring, the rigidity and stability of the produced flooring, their adaptability to form` `aconcrete unit with the poured concrete.

The hollow blocks of our invention possess all of the above, and othervaluable novel features, as will be evident upon a consideration of our speciiicationancl its accompanying drawing.

Our invention relates to hollow building blocks adapted particularly for `employmentr with `light l weighti'steel I-shaped beam joists and are vol? such construction that may be positioned between such beams and rmlylocked inplace by means-o1` `wedges or concrete poured between them, the construction `and arrangement being such that a layer of concrete thereon `may be unified with concrete between the blocksand the blocks themselves thus producing are-pr`oof lightfloor'construction of greatrigidity,A 1 A f two skew blocks only instead of two skew blocks,

a number of intermediate blocks and a'key block incident to previously known construction. These skew blocks can be made of clay, concrete, gypsum or any similar material which `can be formed into precast shape. The blocks-are approximately the same height `as the steel joistsand are;

usually provided with a ange on the bottom `which nts under the V-flange ofthe I-beam so as in the center is such that when they `are placed against the joists there is a wedge shaped space left between them which may vary from Zero toabout 1" on the bottom. Awedge of variable thickness made of concrete, clay, gypsum, steel,

wood or any other suitable material is then inserted and forced downtight.i This wedge will then hold the beams in position. A stiff grout'is Vthen poured into-this joint and also into thej The` thickness of the. wedge should besuch thatV than 1"?.

Our invention consists of a oor ar'chfmade of locks.

` our floor. construction. r

the wedge after it is driven into theslotremains near4 the top ofthe blocks so as to be'able to take care of the arch thrust. If the wedge would be selected thatvwas'too thin it'would go too far to the bottom. Sucha wedge would nothave any G0. value for holdingfthe arch.` .The construction of this arch system differs from the usual arch in the omission of the intermediate and the keyy blocks. v, l However,` these .wedges can be omitted. `If'the 65 blocks are erected as shown in Figure 2 where a temporary plank 43 is set up, the blocks are laid on this plank and at the same time held up on the bottom flanges of the I beams. After they are all laid a cementrgroutior concrete is poured 70, into the wedge spacebetween the blocks and also between the space between they blocks and the' joists. After the cement is set this makes a'solid oor construction.` y

The disadvantages of the present employed key v block are that, if thesteel isnot set accuratelyA on centersso as to t theblock'sizes on hand, the key `block may either Anot drop down far i enouglnwhich will make itstick out on top, or

itv may drop down toofar which gives an unsatisfactory ceiling. In practice the steel joists are usually not spacedvery accurately. The spacing varies` often from a fractionof an inch to more Innour systemwe make the two blocks small 85. enough to t into the smallest space and by then pouringcement between the blocks it is not neces-` sary to wedge them tight against the flanges and anyr varying space betweenthe blocks is taken vup by the cement which is llecl into the spaces.

The novel and'useful features of our invention are clearly -set forth in the accompanying draw-J ing with our descriptionthereof.

In the accompanying drawing illustratingv 4modified forms of our -inventiongrsimilar parts are 95` designated by similar numerals.

Figure pfl is a section through the line 4--4 of'105 Figure 3..v i

Figure 5 is an end View of a modied' form of` The particular form of our iloor construction shown in Figures f1 to 4 inclusive comprises the 110 two steel I beams 15 and 16, having'the

webs

17 and 18, and the flange ends 19, 2i), 21 and 22 respectively.

A plurality of skew blocks are then positioned 5 as shown.` These particular skew blocks comprise a bottom 23, an angularly positioned side 24, a top 25, a curved or inclined side 26 having a recess 2'?y therein and aA diagonal transverse strengthening wall128, vthe bottom 23 extending as a flange beyond the side 26 in orderthat the two blocks upon opposite sides of a beam will practically meet below the beam lower flange to protect its under face.

The inclined part 28 of the blockis on the side next to an I beam. Due -to5 this inclined part, the block can be dropped into position from above by revolving it around the recess27,pin

engagement with the lower flange of the I` beam, the inclination of the side 26 being sufficient to clear the top flange of the I beam.v Also the outer side 24, as yit swings downward, will clear the outer side block. Y

It will be noted that the web 28 in our Yblock 25. runs diagonally from the topcenter between the beams tothe bottom near thebeams. The advantage of the inclined web 28 is that it carries the load the same as inY an arch direct from the center between the beams to the lower flanges 30.Y of these beams, and such -a block is thus much stronger.

`A`series of these skew blocks are positioned along the two faces of the beams, the blocks being of such'width that there is a space between the

walls

24, 24,.of opposed blocks.

f Most desirablyfthe blocks, such as 37, 38, 39, 40, 41 and 42, are-laidon a temporary plank 43, as shown in Figure 2, wedges,such as 29, 30, V31, 32 and 33, shown in Figure 1, being omitted.

Cement groutV 35.is then poured over the whole floor area which fills all the empty spaces bei tweenthe blocks and around the I'beams., This grout can be made flush-on top with the blocks or it canbe raisedabove the blocks as shown at' 45136 on the left of Figure 3. After this cement grout is set the plank is removed.

-It will be Vnoted that, the lower and upper fiat faces ofreach skew" block, provided respectively k byrits lower and

upper walls

23 and 25, are parallel with one another. With opposed series of these blocks in the oor, as above described' and showny in thedrawing, the lower faces of 'the' These skewiblocks are firmly locked in place and to the I beams by means of the cementitious material 35 between the spaced opposed upwardly flaring inclined faces of their sides 24 and also between the inclined faces of their sides 26 and -1 beams. Thelower portions .of the side walls 26 areshown as abutting against the web faces of the I beams. The exposed flange end faces of the beams at the top, as well asalso the top faces of the blocks, can be covered by means of the 7@ cementitious material .36, which is shown as formed in the same mass with the cementitious material-35.

It will thus be seen that our construction comprises'a unified mass of cement comprising Athe ,blocks and the poured cement, supported by the of a' previously positioned opposedV shape, number, arrangement and composition of parts as shownand described as these are given simply'as a means for clearly describing our invention.
