p 1940. H. MUELLER El AL FORM HANGING DEVICE Filed July 10, 1957 Patented Sept. 24, 1940 UNITED STATES 'OFFICE v a 1 2,215,972 j a FORMHANGING-DEVICE V Henry Mueller and George B. Bosco, Chicago, 111. I Application July 10, 1937, Serial No. 153,625 T I 7 Claims. (01425-1315 a This invention-relates to, a device for hanging floor forms from supporting beams and to a method of assembling floor forms on which cementitiousmaterial is poured to form a concrete floor. f
Anobject of the invention is toprovide an economical, positive, strong, fool proof, adjustable, readily assembled and disassembled device for" hanging fioor forms on floor supporting beams. e
' Another object of the invention is to provide a device of the above stated character by which the floor forms may be placed without the aid of scaffolding and from above the supporting beamsfor said forms.
.Another object of the invention is to provide a method of assembling floor forms upon supporting beams from a position above said beams.
Another'object of the invention is to' provide a simple, eccnomicaland easily assembled floor form structure supportable directly upon the permanent supportingbeamsfor the floor.
Another objectof the invention is to provide means'for supporting the floor forms upon the supporting beams in such manner that upon removal of the forms no projecting parts, members or metallic surfaces shall be left exposed to mar either surface of the newly laid floor.
Another object of the invention is the provision of means of the above stated character incombination with simple and economical seal ing means for preventing spilling over the soft concrete on the external surfaces of the lower flange and/or'web of the supporting beam, which is commonly a steel I'-beam. I
' Other objects and advantages of the invention will be apparent from the following description when taken in connection withthe accompanying drawing, wherein:
Fig. 1 is a view in perspective showing floor formsconstructed and supported in accordance with this'inventio'n. a
Fig. 2 is a transverse vertical section showing the supporting device of the invention and a 7 floor laid uponthe floor form supported thereby. Fig. '3 is a fragmentary view in perspective of the supporting device of- Fig. 2 and showing the manner of assembling. the. flooring of the floor forms upon said device. I
Fig, 4 is a, plan View of a modified supporting device.
The preferred embodiment of the floor form supporting device consists of a bar or a piece form of the of, channel iron 2 slightlylonger than the width Of e rl se es F.- l eeire iee $199 terms ar to be mounted. e-channel irons- 2 are provided at their opposite ends'with openings 6 to receive elongated bolts or threaded rods 8; the bolts or rods 8 each being-provided with a head 18 at one end and With-threads l2 attheir other ends.
Bolts l4, each having a retaining head It? and an integral sleeve portion l8; are threaded to IE? ceive the threads II of the bolts 8. The heads ID of the bolts support metallic plates 28, each of which has an opening 22 to receive the shank of the bolt 8 and-a slot 2"4extending radially from the opening-Z2. I The floor forms are assembled upon these supporting devices and the I-beams 4 in the following manner.
Longitudinal supports, stringers of joists Z6 are'drilled' at their ends, and intermediately if desired, toreceivefthe shanks I of the bolts 8. These beams, which may be 4 x 4 wooden beams or their equivalent, are assembled on the bolts 8 and rest upon the plates 20* disposed atthe ends of the beams. A common nail 21 or'other fastening-"device is received-in the slot 24 of each plate and secures the beams against movment'relative to the bolts, the head of each nail or other fastening device. preferabl'y engaging the head [0' of its associated bolt 8 as shown in Fig. 2 The assembly of the stringers 26 with the bolts 8 andplates 20- maybe efiected on a workbench and thereafter a pair of stringers with the bolts 8' attached thereto are transported to and assembled upon the I-beams' from a position' above said beams. The bolts 8" are passed 'through'the openings 6. in the channel irons 2 and the sleeved nuts M are then loosely threaded on the bolt to retain. the assembly on the Lbeams 4 during. the subsequent construction of theremaining portions of the floor forms on said stringers; ,On' toplofthe stringers 26 are placed transverse beams 28-, which are preferably! x 4 wooden beams slotted at their ends, as at 30, to receive the bolts 8 associated with transversely spaced I- -beams.. An.additional.transverse beam 32 may be positionedupon thestringerslli intermediate the beams 28- and may be fastened, if desired, in
any suitable manner to'the stringers 26. Flooring strips 34. are placed upon the transverse beams 28 and 32 and are provided 'at their corners with slots or recesses 36 receiving the bolts 8. The floor strips 34; may comprise panels of Wood or any other desired material extending between each set of supporting devices. H l
To insure against'slopping over or spilling of the soft concrete onto the'exte'rnal surfaces of the I-beams, rubber strips 38 are placed: between the under surface of thetop flange of said I-beams jthe sleeved nuts l4.
and the floor panels 34 to provide a seal. The floor panels having been placed in position, the sleeved nuts l4 are drawn up tightly to clamp the rubber strips 38 securely in position between the top surface of the panel and the I-beams.
If desired the floor forms may be assembled in their entirety on a work bench and then placed in position on the I-beams, the assembling on the I-beams being accomplished from above said beams.
The sleeves l8 of the nuts I4 prevent binding of the bolts against the channel irons 2 when the structure is finally clamped in place.
The floor forms having been clamped on the channel irons Z and floor panels 34. After the concrete has set, all the elements of the floorforms and the clamping devices may be removed, with the exception of the channel irons 2 and This is accomplished by first loosening or withdrawing the nails 21 or other fastening devices employed to secure the beams or stringers 26 to the plates 20 and then rotating the bolts 8, by conventional tools applied to the heads l0 thereof,-to withdraw the same from the sleeved nuts I 4. Upon Withdrawal of the bolts 8, the floor forms are removed from below the ,set concrete leaving only the small openings from which the bolts 8 have been withdrawn to be pointed up. It will be noted that the under surface of the concrete floor, which comprises the ceiling of the floor below, is left clear and without projections, parts, or metallic members to mar the appearance of said surface.
gThe upper surface of the floor is similarly clear and unbroken.
If desired, each section or panel of the floor forms may be removed as a unit when the concrete has become set and immediately transported to and reused in another location by simply inserting the bolts 8 of each withdrawn sec- ,tion in new channel irons 2, new nuts I4 being provided to replace the nuts left embedded in the concrete. I
In Fig. 4 is shown a modified'form of channel vmember for supporting the bolts 8 and floor forms any convenient manner, as by welding, to the forward, straight, intermediate portion of the wire. The bolts 8 pass through the looped portions 42 of the wire and are clamped thereto by the sleeve nuts M. It will be seen that in this construction a limited amount of adjustment is provided between the supporting channel and the bolts 8 whereby said supporting device may serve for various sizes of floor beams.
