Fnanr'noorl FLOOR, (i-BEAM CONSTRUCTION.)

Specification of Lettere Patent.

Patented March e, 1909.

Application led October 20, 1903. Serial No. 458,648.

To all whom it may concer-u2l A Be it known that l, Dnri'nn H. MAGDIEL, a subject of the Crown of Great Britain, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain vnew and useful Improvements in Fireproof Floors, (I-Beam Constructioin) of which the following is a specification.

The invention is in the nature of a nevv and practical improvement in reinforced fireproof floor and ceiling` construction for steel buildings. f

The object of the invention is to make a combined fireproof ioor and ceiling and to make it strong, and rigides any other construction known.v lt is also designed to save time and costly labor.

My invention consists in the novel construction of the door block and its combination and arrangement in relation to the supporting,` I-beains and the reinforcing members, whereby .the floor may be laid without upright centering supports and whereby a inislied floor and a finished ceiling are formed at a greatly reduced cost, as hereafter more fully described with reference to the drawings in which,

Figure l, is a side view of the lioor blocks shown applied between the I-beams on. temporary supporting devices, the blocks-helingT of a construction 'adapted to .ferm a licor on the upper surface and a ceiling on the lower surface, la is a perspective view of the joint .formed by the two blocks at an l-beam, Fig. 2, is an end view of one of the licor blocks and. Fig. 3, isa view similar to l, but showing a modification of the floor block in which the lower ceiling por tion is omitted.

Corresponding and like parte are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

ln the preferred embodiment of the invent-ion the blocks l of concrete are made hollow and .strongly reinforced throughout. The upper reinforcement i2 is of stout Wire embedded in the ioor slab and protruding out through the ends of the block and bent over and hooked around the .upper flanges of the I-beams or other structurel steel, or

support, as seen inFigi'd, thereby making a continuous bond throughout the door.

The reinforcing in the ceiling part-includes Wire 3 and rod i Fig. la, Which rod passes through a rib 5 cast in the middle of the block along the upper edge of the ceilingslab. About the middle of the block the floor and ceiling:r slabs are integrally formed with a web 17 through Which passes a vertical metal reinforcing suspension rod 6 tied to the upper reinforcing :2 and the lower rod 4 so as to make a stitf bend joining the iioor and ceiling` parts of the block together and causing the ceiling member to be suspended from the upper wires 2, which are anchored to the tops of the -beams. The reinforcing wires 2, 4 and l5 protrude out through the end of block l so that they can be embedded in the .concrete grout T which is poured between the ends of block 'l and the -beam S. The ends of the block ore cast With horizontal corrugations 9 to forni keys for the grunt 7 so that when the latter sets, the block is Wholly self-supportinte even if there were no reinforcing.

To temporarily support the blocks, planks lO are held in position beneath the l-beams by hangers 1l and when the grout has set` thoroughly the hangers l1 are cut, and the plank l0 is taken down, the ceiling then being level. l

lh the air spaces l2 of the block 'there can. be concealed Wiring, and pipes for plumbing., heating, etc. The upper edge of the rib is formed with seats 16 to receive such pipes. Along the upper edges of the block are formed curved recesses ltl which, wit the corresponding recesses ofthe adjacen blocks, form a trough which is to be iilled with grout after all the blocks are laid side by side, to makethe floor tight throughout and form a key. The grooves are undercut for this purpose.

The blocks are factory made, or may be made onfthe job, and can be handled and put in the Jdoor quickly and easily, the floor being ready to Walk on as soon as laid. The blocksI are, as shown, of a dimension of twelve inches, more or less, in Width and seven feet, more or less, in length, are fiat on top to formv a finished door, and of a CII f depth to Sua are I-beam, Weich naar should be of less vertlcal' height than 4the blocks to allow the upper reinforcing to come straightalso holes 14a; these allow for the passagey of pipes and wirin when it is desired to carry ,them lengthwise the blocks and when not so required the inner ends ofthe holes 14 may be closed and thematrix of grout will then enter in the form of tenons into the outer ends of holes lll to make a more substantial bond between the blocks and .the said matrix of grout aboutthe -beam.

From the foregoing description it will be seen that the floor and ceiling block forms a complete floor and ceiling and without other accessories and is a cheap, practical and strong construction in which the blocks may be made in advance in the shop and be quickly applied in the building. It will be seen, also, that no expensive upright centering timbers are required, since the -beams carry the weight of the floor as lthe blocks are laid,l and yet these ifi-beams are coinpletely embedded in a matrix of grout which not only fills in the spaces between the ends of the blocks and4 the I-beams, butalso eX- tends over the tops of the l-beams, covering holding, and hiding the anchorage ends o the reinforcing wires or rods where they' are hookedaround the top of the I-beam, and filling this space flush with the tops of the blocks, so that it forms a perfect floor on which the floor covering may be laid, said.

" grout also flowing under the I-beam and.

filling the space belowl it flushwith the bottomof the block, so as to hide the -beam and make a finished ceiling below. An important feature in securing this result is to be found in making the floor blocks of greater vertical depth than the I-beams, so that the vupper surface of the block extends above the I-beam far enough 'to allow the grout tov cover the hooked-over ends of thewires and hide the same, thus makinga floor surface flush with the tops of the Nblocks, and also' allowing the grout to How under the -beam to embed and hide it and make a .finished ceiling surface flush with the lower surface ofthe block. While these great economic advantaves are secured, the l.anchorage of the relnforcing wires or rods to the I-beam and the terminal'wires extending at dierent levels from"`the corrugated ends of they blocliiinto' thegrout make a thoroughly strong and substantiai!a construction,- when the matrix of'grout-has set, forminga'simple, practical, and strongoor, that can be may be used at once for any iighttraffic,

since any one door block is sustained at both ends from the -beam by the planks, stir- `rups and anchorage rods' 2, and at both sides by theadj acent blocks through the interlock of the cement keys 'in the undercut grooves 2 being anchored to the I-beams'and the snspension member 6 being` anchored vtoboth the upper rods 2 and the lower rods 4, the Weight of the lower or ceiling slab, in the middle, is transferred by suspension to and .carried by the I-.beams through the rods 2..

The separate wire ends which protrude through the ends of the blocks as free' ends. v

It will`also be seen, .that the upper rods of the blocks to be embedded in a matriit of j grout, and anchored to the I-bearns, and the blocks being made at the ends of greater vertical depth than the height' of the I- beams, the upper part ofthe blocks extending above the tops of the I-beains and the lower part of the rend ,wall of the blocks exi tending below the bottoni of the I-beams and a matrix of grout extendingover" the top, down the sides and Vunder the bottom ofthe I-beains flush with the u per and lower ends-f of' the blocks, and embed) reinforcements ofthe blocks to make .a iinished floor above,I and ag'finished ceiling below.
