1 CONCRETE I'LOOR CONSTRUCTION.
I forms, designated genericadly by the numeral 3. '1 use in crass sect ion are approximetelv U-Hhnpml and are formed with eidee 4; an the connecting bottom web 5. As seen from Fig. 2, the ends of the sides 4 are cut away at an inelinutimi, these inclined ends extending down nearly but not quite to the bOtiOlll of the form 3 end from this point the end of the form iscnt vertically downward as at 6. The upper ed of both the sides 4 are outwardly tlan ae'at 7, three flanges being mntinucd own the inclined ends as et 8. A: seen from Fig. 1, each flange 8 in wider at the bottom then at in Cl" wurd hn the etre ght portion 6 but is bent outwardly in line with the longer axis of the form as at 9 so as to provide feet or lugs ad! ted to be engaged with the lower flen of t e I beams so that the forms 3 may1 a. supported therefrom. The elevation of t em feet 9 above the bottom 5 allows the form 8 to projcctdown beyond the bottom of the beams 2, up shown m Fig. 2.
Each of the forms 3 is connected to the next adjacent form by u plate'10 hevin downwardly and outwardly inclined en o 10' to lit over the inclined ends of the adjacent forms. At the lower ends the in clined form nngcs 11, which fit u on the upper face of the adjhccnt feet 9. he side edges of the plate It? are downwurdly flan ed as It 1'2, ea ehown elenriy in Fl 3. w en in place the margin of the )la e 10 overlepe the inner edge of the si e 4 of the form and extends down a inst said side, the

A tie rod 15 may also be used at intervals pansittgdltrou h the inclined ends 10' of certain of the p ates 10, through the concrete at the ends of the'strueturn and being provided with the usual nuts'for the purpose of adjusting it in place.-
It. will be seen that any downward pressure upon the tloor acts not out against the concrete arch, which would be t w case if the forms were taken away, lntt also act against the metallic arch formed'by' these forming plates and that thus the tleor'is made doubly strong. It has not only the strength ofthe concrete arch tied by the tie rods 15 but also the stren th'of the metallic areh, the meatbers of which, because of their tlangcd edges, are partlenlarl y strong. 'lhua the beam 'Ol'lllttt" member it. though it may he made of taunparativcly thin metal, is yet so stillcned by the llangca 7 and 8 attd by the fact that it has two parallel upstanding side walls that it woult support-of itself a considerable weight. The plates 10 connect these so ntrate beam-like forming members 3, and t me all strain is distributed over a number of beam like forming members.
