mounted in channel 34 tor a purpose disclosed hereinafter. It will be noted that the anchor clip 36 is of a llength appreciably greater than the lengthof arm 28 of bracket 24. At its extremities, bracket 36 is provided with outwardly extending

flanges

38 and 40. Flange 40 is provided with a short inwardly directed lip 42.

Supporting

brackets

22 and 24 are securedly lixed to the web portion 14 by bolts 32 as shown in FIGURE 2. Bolts 32 have shank portions which pass through holes 30 in the support brackets and holes 20 in the web portion. As shown in FIGURE 2, bolts 32 clamp the sup- .portin-

g brackets

22 and 24 to the web portion 14 on opposite sides thereof with the anchor clip 36 disposed in the channel 34 of each of the supporting

brackets

22 and 24. It will be noted that the longer arm 26 of the supporting brackets is horizontally disposed and that the shorter arm 28 is vertically disposed. The ange 40 on the anchor clip 36 is of suicient width so as to support the lower extremity of the shorter arm l28 between the lip 42 and the upstanding body portion of the anchor clip. As mentioned above, the supporting

brackets

22 and 24 are disposed at spaced points along the length of the web portion 14. Extending along the length of the I- beam 12 on opposite sides of the web portion 14 there is provided a form support 44 which is supported in a horizontal plane by

support brackets

22 and 24. The anchor clip 36 is of suicient length so that the flange 38 slips over the uppermost surface of the form support 44.

Each of the I-

beams

12, 12', and 12 is provided with

identical support brackets

22 and 24 and form sup- FIGURE 7 is a cross-sectional view of an alternate embodiment of applicants invention. i,

Referring now to theWdrawing in detail, where like numerals indicate like elements, `there is shown in FIG- URE 1 a cross-sectional view of applicants iloor construction in `an intermediate stage. l

There is shown in FIGURE l a plurality of I-

beams

12, 12 and 12 which .are disposed in parallel relation in a horizontal plane. As is conventional in the art, the |I- beams are supported at their extremities. Each of the I-

beams

12, 12', and 12" and their form `supports are identical. Therefore, it is deemed sufcient to describe `only one of these l-beams in detail.

Referring to FIGURE 2, it will be seen that I-beam 12 comprises a web 14 and parallel flanges 16 and 118. Web 14 is provided with a pair of holes 20 at spaced points therealong. At the various locations of the holes 20 along the I-beam 12 there are provided a pair of supporting

brackets

22 and 24. Since the supporting

brackets

22 and 24 are identical, only bracket 24 will be explained in detail.

Referring to FIGURE 3, it will be seen that supporting bracket 24 is generally L-shaped. The longer leg of the bracket 24 is designated by the numeral 26 and the shorter leg is designated by the numeral 28. It will be noted that the shorter leg 28 of the bracket 24 has a pair of holes 30 therethrough. The spacing of the holes 30 in bracket 24 corresponds to the spacing of holes 20 in the web 14 of the I-beam 12. The shorter leg 28` of the bracket 24 is provided with a channel 34 which extendsthroughout its length. An anchor clip 36 is ports 44. Intermediately disposed between adjacent I- beams there are provided forms 48. Each of the form supports 44 is provided at its outer extremity with a shoulder 46 which supports the ends of forms L48. To prevent the forms 48 from moving relative tothe form supports 44 there is provided a tiller 50 on the shoulder 46. Filler 50 may be of metal, wood, or plastic. It will be seen that forms 48 will support the bulk of the poured concrete and as a result tend to pivot the `form supports 44 with relation to the supporting

brackets

22 and 24. `'I'he ilanges 38, y40, and 42 of the anchor clip 36 prevent any pivoting movement between form support 44 and supporting

brackets

22 and 24. I-f desired, reinforcement 52 `is provided with .portions disposed above and below ilange 16 of I-beam 12.

The operation for pouring the concrete floor is as follows.

I claim:

The I-

beams

12, 12 and 12 are supported at their extremities and disposed in parallel horizontal disposition.

The supporting

brackets

22 and 24 with the anchor clip -36 disposed within the channel 34 of the supporting brackets are bolted to the web portion 14 of each I-beam at spaced points along the length of each I-beam. Form supports 44 are disposed on each side of the web portion of each I-beam with the form support dis-posed between 4the flange 38 0n the anchor clips 36 and the horizontally disposed arm 26 of the

brackets

22 and 24. Forms 48 are placed between adjacent I-beams and supported on the form supports 44. Filler material 50 is then inserted to prevent relative movement between forms 48 and lform supports 44. The reinforcement 52 is disposed as shown in FIGURE l and then the concrete is poured over the reinforcement 52, flange 16 of the I-beams, and onto the `forms 48. Before the concrete has set, the upper surface of the iloor will -be made smooth by any well known manner. After the concrete has had sufficient time to dry, the bolts 32, supporting

brackets

22 and 24, lform support 44, and forms` 48 are removed.

The above process is repeated until all of the concrete oo'rs in the buil-ding have been poured.

yReferring to FIGURE 4, there is shown an alternate embodiment of applicants invention. The embodiment of FIGURE 4 is substantially the same as the embodiment in FIGURE 2 except for the securing means which holds the supporting

brackets

22 and 24 in assembled relation with the web portion 14'. At spaced points along they length of web portion 1'4, there are provided a pair of supporting brackets22 and 24 which are aflixe'd to the web portion 1`4 by threaded stu-ds 56 which are driven through the supporting

brackets

22 and 24 and into the webV portion 14 lby an explosive charge. The apparatus for shooting the threaded studs 56 is of conventional construction and very popular in the construction eld. The 'use of threaded studs 56 and the aparatus for shooting the same eliminates the necessity for drilling holes in the web portion of the I-beam and in the supporting brackets.k Since there are no bolts or bolt holes, the use of threadedstuds 56 lends itself to more rapid assembly of the supporting brackets and the web portion of the I-bea-m.

The operation of the embodiment shown in FIGURE 4 is the same as the embodiment disclosed above. After the concrete has `dried and the supporting structure has been disassembled, the threaded studs 56 will be thrown away.

`FIGURE 5 discloses another embodiment of applicants invention. I-beam 58 is provided having

end flanges

62 and 64. It will 'be noted that the

end flanges

62 and 64 have tapered surfaces 66 on their inner sides thereof. Suppc'rting brackets 68 and 7-0 are provided with tapered bottom surfaces` 7 2 which are supported on the tapered surface 6 6 Vof the end flange 62. Each of the supporting

brackets

68 and 70 is provided with a channel 74 which extends Vinwar'chily from one end ofthe

supportingbrackets

68 and 70. It will-be noted that the channel 74 has a and 90 parallel to one another. Therefore, the supporting

brackets

68 and 70" have parallel end surfaces. ,The supporting

brackets

68 and 70 are secured to the I-beam 88 by bolts 91 which pass through holes in the supporting brackets and the web portion of the I-beam 88. The anchor clips 78, the for-rn supports 83, andthe forms 84 are exactly identical with the showing in FIGURE 5.

`FIGURE 7 discloses another embodiment of applicants invention. The I-beam 12, the supporting

brackets

22 and 24, and the bolt 32 are substantially the same as shown in FIGURE 2. The form support 93 differs from the form support in any of the previous embodiments since its width is less than the width of the supporting

brackets

22 and 24. Thus, it will be noted that this embodiment does not use an anchor clip. The form supports 93 and 95 extend longitudinally along the length of the'I-beam 12 and are disposedv on opposite sides of the web portion 14. Disposed in horizontal parallel relation and extending between adjacent I-beams there are provided

form joists

96 and 98 which are supported at their extremities 'by form supports 93 and 95. The forms 48 are horizontally disposed on the upper surface of the form joists 96 and 98. Alternatively, the form joists 96 and 9'8 could rest directly on the bracket supports 22 and 24.

lThe operation of this embodiment is substantially the same as set forth above. The use of form joists 96 and 9 8 permits this embodiment to be used where heavier Y hole through the web `portion of the I-bearn.

length which is' less than the length of the supporting e brackets 68 andH 70. vAt one end vof the supporting brackets 68 and 70 'there is providedal transverse slot 76. Within 'the channels 74 there are provided anchor clips 78. Each anchor clip 78 is provided with Aupstanding llanges "80 and 82. Each of the anchor clips 78 is disposed within the channels 74 of supporting Brackets 68y and 70.Y The flange 82 of the anchor clip 78 is disposed within slot 76 in each of the supporting

brackets

68 and 70. A pair of form supports 83 are provided, one of each form supports being 'disposed on opposite sides of the web 60 of the I-beam 58. Each form support 83. is mounted in a horizontal position on the bracket supports 68 and 70 with the anchor clip flange 80 disposed above the uppermost surface of each form support. Between adjacent I-beams there are provided forms 84 which have their extremities resting on opposed form supports 82.

To prevent relative movement between the form supports 83 and the forms 84, there are provided fillers 85.

'A C-clamp 86 is provided for maintaining the supporting

brackets

68 and 70 in assembled relationship against the web portion 60 of the I-beam 58. As shown, the C-clamp is of conventional construction and need not be `'discussed in detail.

Theoperation of this embodiment of applicants invention is substantially the same as the embodiment shown in FIGURE 2. The provision of a C-clamp as the securment Vshown in FIGURE 5. The I-beam 88 shown in FIGURE 6 is of the same type as the I-beamshown 'in FIGURE 2. The l-beam 88 dilfers from the I-beam 58 by having the inner surfaces of the end flanges 89 floors are required or where it is desired to space the I-bea-ms a greater distance apart from one another. 1,

In each of the embodiments shown in FIGURES 2, 6, '7, it 'is possible to eliminate the necessity for drilling a In this case, studs having threaded ends would be disposed on opposite sides of the web portion and welded thereto with the threaded ends extending radially outward. The studs would extend through holes in the support brackets and a nut would be provided on the threaded end of the stud so as to hold the support bracketsin assembled relationship with the web portion of the I-beam.

The present invention may be embodied in other specie forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specil'ication as indicating the scope of the invention.
