FRAMING-SUPPORT FOR CONCRETE CONSTRUCTION.

Specification of Letters Patent.

. Patented April 7, 1908.

Application filed. August 1 1997. Serial No. 388,&68.

To aZZ whom it may concern:

Be it known that I. THOMAS 001mm, 9. citi' zen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new anduseful Improvement in Framing-Supports for Con-' crete Construction, of which the following is V a full, clear, and exact description, reference means .ot-"joists extending from one structural iron beam to another-and supported therefrom. So far as Iam aware, the universal manner of supporting these joists from the beams is by means of a suitable number .of wooden sup orting blocks which are suspended from t e lower flanges of the beams y means of bolts, the upper ends of which are bent to permit them to engage the flanges of the beams. Small wooden spacingblocks ofsuflicient height to silpport the joists in proper position are naile or otherwise temporarily secured to the supporting blocks which are suspendedfrom the beam flanges. The preparation of the woodensupporting and spacing blocks requires a large amount of labor and, as the distance at which the joists will be sup orted from the supporting.

blocks varies in ifferent buildings, 1t is generally necessary for the carpenters to make new sets of spacing blocks meach building and often to make new sets of such blocks for the different floors in the same building.

sary to rotate-t e bolts by which they are.

supported to permit of the disengagement of. the bolts from the beam flanges. -'This results in tearin 'lar e and irre ular holes in the. concrete winch as been ed in around the beam, and these holes have to be filled in, in order to make a finished-appearance in the beam.

It is the object of my invention to provide framing sup orts which are permanent and durable in .c iaracter, which can be readily applied to and removed from the structural iron beams from which the framing is to be supported, whichwill be capable of quick and ready adjustment to support the joists employed with the decks of the different floors, to arrange the parts so that there will i be no liability to the clogging thereof by the concrete, and to reduce-togaminimum the amount of filling or finishjii 'gf-whichmust be done to the' concreteiincased beams after the supports have been removed therefrom.

' accomplish the above results by the embodiment of, my invention illustrated in the drawings forming a part'hereof, wherein Figure 1 represents a view in elevation of a device constructed in accordance with my invention, the structural iron beamsbeing shown in section and parts of the dev ce being broken awayand shown in. section for clearness of illustration Fig. 2 representsa sectional view on the correspondingly numher ed line of Fig. 1 looking in the direction of the arrows; Fig. 3 represents a sectional yiew on the line 3-3 of Fig. 1 looking in th ed1rec-' -tion of the arrows; Fig. 4 represents a sectional detail on the correspondingly num-' bered line of Fig. 1; Fig. 5 represents a sec tional view taken through the flooring and showing the temporary framing therefor supported by devices constructed inaccordanc'e with my invention. I 1 Describing the parts by reference numerals, 1 represents one of thestructural iron floor beams, the same being shownas an I-beam, from-the opposite flanges of which m supporting devices are carried. Each 0 these devices comprises generally a base or sup: porting member 2 which extends transversely of the beams; clips or clevises 3 carried thereby and adjustable longitudinally thereof forengaging and disengaging the flanges of the beams, and vertically adjustable carriers 4" carried thereby'for supporting the framing joists.

lhe sup orting member or base 2 is conveniently ormed from a pair of sheet metal plates 5 secured together at the central and end (portions by means of rivets 6,-* with spacing sleeves 7 interposed therebetween.

' These spacing sleeves may conveniently be back to form an I-beam and provided with perforations 9 through the webs whereof. lhese perforations are adapted to receive the pin 10 which restsonthe upper edges of plates 5 and supports the carriers in. any desired position. The distance between the centers of the perforations 9 may be i or 7}, and the length of the carriers will be such as to enable them to accommodate all ordinary variations in depth of flooring and floor beams, as well as of the joists by which the deck is carried. Each carrier 4 is provided ;at its upper end with theyoke 11, which may be conveniently formed by a pair of angular or Z-shaped plates 12 having vertically extending portions adapted to fit in between the flanges of the channel bars 8 and secured to the webs of said bars as by means of rivets 1.30. The upperends of the plates 12 are each provided with an aperture 13 for the reception of a nail or other securing means 14 whereby the joists may be temporarily secured thereto in such manner as to prevent their lateral movement.

The supporting member or base 2 is also provided with a pair of adjustable clips 3 to which reference has been made herein before, each of said clips comprising a clevis or.

flange-engaging member 15 and a clamp therefor. The clevis 15 is provided with a base which rests on the tops of the plates 5 and is provided with an upwardly and inwardly extending portion or hook 16 adapted to engage the outer upper surface of the beam flange. To clamp said clevis in osition, I provide the same with a bolt 17 12W- ing at the upper end a rounded head 18 which covers the angular aperture through the base and protects the ame' from access of the concrete thereto. The upper portion of the shank is an ular to fit the a erture in the base, and the body of the shan extends downwardly between the plates 5 and is provided at its lower end with a U-shaped washer 19, the upwardly projecting flanges of which engage the lower edges of plates 5. Bolts 17 are provided at their lower ends with nuts 20. By the arrangement described and the employment of the washer 19, the clevises may be adjusted longitudinally of the supporting members or bases withoutaltering their angular relation thereto.

y bending a piece of sheet metal ofand In Fig. 5 there is illustratedthe manner in which my invention is utilized to support the framing and the concrete flooring thereon. In this view, 21 denotes the joists by which the deck 22 is su ported, 23 the boards which inclose the-lhw'er portions of theibeams and form a receptacle for the concrete material in which the beams are to be embedded; 24 denotes a, common form of metal reinforcing bar or strip by means of which the concrete when hardened is supported from the tops of the I-beams.

It will be readily seen that the carriers 4 may be quickly and conveniently adjusted to su port the joists, no matter what may be .the depth thereof or the distance of the lower faces thereof from the supporting member orbase plate 2, and that when the concrete flooring 25 is hardened, the task of removin the framing is a very small one, it being on y necessary to withdraw the nails 14 and move the clevises outwardly to disenage the supporting devices from the I-beam flanges. 4

It will be observed that the distance between the outer face of each clevis and the inner face of the adjacent carrier is suffi cient to permit the blevises to be moved outwardly until their inner ends free the I-beam flanges. This obviates the necessity for twisting each clevis on a pivot in order to disenga e the same from the I-beam, with the resu t that only small and even apertures are left in the concrete materialby the removal of the clevises therefrom, which apertures may be quickly and easily filled. Furthermore, the task of recessing the bottoms of the boards 23 for the reception of the inner ends .of the clevises is light compared with the recessing which must be done to permit 5 the turning of the bent ends of the bolts which are usually employed to hang the wooden supports from the beams. Where fine adjustment is desired, the apertures 9 may be staggered, as shown, and the employ- 110 ment of the apertures and pins provides an adjustable sup ort' for the carriers which is free from liabi ity to clog bythe access of cement or concrete thereto.

Having described my invention, I claim: 5
