' BEAM HANGER Filed June 25, 1932 INVENTOR OMmr/rham,
Patented June 4, 1935 PATENT. FF1:E f P 2,003,635 BEAM HANGER Charles M. Markham, Detroit, Mich. Application June 23, 1932, Serial No. 618,976
.1 Claim.
My invention relates to hangers for use in hanging concrete forms ormolds from supporting beams. Y a 7 It is an object of the present invention to provide a hanger for concrete forms which maybe supported entirely from the girder or beam around which the concrete is to be molded and which will do away entirely with extraneous supports of any kind. r i
It is another object of the invention *to provide an improvedcross member by supporting the soflit sections of the mold and to provide improved suspending means for this cross member by which it may be readily fastened in position without the use of any special tools whatsoever.
Still another object of the invention is to provide an improved form of connecting means for the ends of the suspending means which will readily :adapt the same to be used with Various sizes of beams and girders without altering either the suspension means or the sofiit supporting cross member in any way.
Other important objects and advantages of the invention will become apparent during the course of the following detailed description of the invention when read in conjunction with the accompanying drawing which forms a part of this specification and in which,
Figure l is a vertical sectional view of an I- beam showing my improved mold hanger applied thereto;
Figure 2 is an enlarged plan view of the means for joining the ends of the suspending strips;
Figure 3 is a perspective view of one end of the mold supporting cross member;
Figure 4 is a sectional view taken on the line 4-4 of Figure 3, and
Figure 5 is a partial perspective view of one of the strip end fittings before the strip is secured thereto.
Referring now more specifically to the details of the drawing, wherein like numerals refer to like parts throughout the same, [0 indicates a beam or girder, in this case shown as an I-beam and from which is suspended a form or mold including a sofiit board H which is spaced from and centered with respect to the base flange I2 of the beam I0 by means of combined spacer and gauge strips I3, said strips being rabbeted along their upper and inner edges to form a seat for the edges of the flange I2.
The soffit board II and other mold parts are supported upon a cross member M which extends transversely of and is suspended from the beam by means of sheet metal strips l5 and (:01. zs lsrs) I'6 which are joined-together over the top flange H of the'beamll) in a manner to be hereinafter described. The cross member I4 is composed of apair of angle'bars I 8 disposed in parallelspaced relation with the angles thereof disposed in oppos'itedirections. The angle-bars I8 are held in spaced relation by means of rods |9 which are formed with reduced ends 'fitted in openings 2! in the vertical flanges 22 of said angle bars.
The strips l5 and i6 each carry a seat member 23 adjacent their lower ends which extends transversely beneath and upon which the cross member 14 is supported, said strips extending down between the angles 18 and secured to "the seat members ad-jacentthe center thereof in the manner hereafter described.
The seat members 23 are each formed of a strip of sheet :metal having the ends thereof bentback upon opposite sides of the middle portion as at 41 and 48 to form a laminated member of triple thickness. The strips l5and ['6 are eachsecured to the seats in the same manner so that a description :of one will suiflce for' both. The lower end of the strip [6 is brought down between the end 48 and the center portion of the seat 23 and then bent upwardly between said portion and the end 41 so as to embrace the center and the free end is then bent down over the top edge of the end 41. Thus the ends are securely attached to the seat members without requiring the use of any kind of fastening means whatever. It will also be noted that this method of attaching the strips to the seat members also permits ready adjustment of the length of the strips to exactly the length desired.
The strip from which the seat members 23 are formed is provided with widened portions at the ends and'also at intermediate points where the bends occur so that when the strip is folded to produce the finished seat, upstanding lugs or stops 49 will be formed at the ends of the seat to prevent lateral movement of the cross mem,- ber off the ends of the seats.
The upper ends of the strips l5 and I6 are secured to connector members 24 and 25 respectively which normally rest on the top flange of the I-beam In, said member 24 being in the form of a bifurcated plate and the member 25 being formed as a substantially flat plate having a tongue 26 formed on one side adapted to extend between the furcations 21 and 28 of the member 24. The free ends of the furcations 21 and 28 and of the tongue 26 are bent under upon themselves to provide opposed flanges 29 and 30 respectively for engagement by a wedge member 3| which when driven into the position shown in Figure 2 will draw the members 24 and 25 together to take up any slack in the strips l5 and I6 and thereby firmly clamp the cross member l4 in position.
Each of the members 24 and 25 are formed with oppositely disposed ears 3233 and 34-35 respectively which serve to aid in securing the ends of the strips l5 and IE to said members. The end of the strip I5 is brought up under the member 24 through the bight portion thereof and bent back upon itself as at 36 whereupon the ear 33 is bent inwardly over this portion 36. The end is then reversed and the ear 32 bent inwardly over the reversed portion 31, the extreme end 38 then being bent back over the car 32. The body portion of the member 25 is struck up to form an eye or loop 39 through which the end of the strip I6 is drawn, the end being then secured in much the same manner as the end of the strip I5. It will be noted that the pointof the wedge 3| is upturned as at 3| to prevent it from being entirely withdrawn. r
In order to provide for securing. the sides of the concrete form in position, slidable clamping members 40 are mounted upon the cross member l4, each of said clamping members comprising a base 4|, and upstanding opposed flanges 42, the edges of the base 4| being inturned under the horizontal flanges of the angles l8 as at 43to slidably secure the clamps thereto.
The horizontal flanges of the angles l8 are each formed with elongated slots 44, the slots in one flange being staggered with respect to those in the other flange, and a wedge 45 carried on the end of a chain 46 secured to the clamps 40 is adapted to be driven into a selected one of said slots to force the clamps 40 tightly into position to clamp the sides of the form in operative position.
In operation, with the seats 23 secured in the proper position on the strips l5 and I6 for the size beam to which the form is to be secured and with the strip l5 secured to the connector member 24 and with the wedge 3| retracted to the limit allowed by the upturned end 3| the end of the strip I6 is drawn through the eye 39 and pulled tight by hand and then secured by the ears 34 and 35 as has been previously described. The wedge 3| is then driven home to draw the strips l5 and 6 much tighter than would be possible by hand and to secure the member |4 rigidly in position. The clamps 40 are then slid up against the sides of the mold and the wedges46 secured in the proper slots to maintain them securely in tightened position. The tip of the wedge 3| may be bent back upon itself as indicated in dotted lines to insure that the parts will not become loosened through accident.
It will thus be seen that I have provided an extremely simple and eificient mold clamp and hanger which may be quickly secured in operative position without the use of any special tools and 'with very little eifort.
7 While a preferred embodiment of the invention has been shown and described, it will be distinctly understood that various modifications in the details of construction and operation may be resorted to without departing from the spirit of the invention within the scope of the appended claim.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: r v
In a beam hanger for concrete forms, a form supporting cross member, strips for suspending said cross member from a beam, seat members carried by the lower ends of said strips and upon which said cross member is adapted to rest, said seat members each comprising a one piece laminated sheet metal member, said strips having the lower ends thereof looped under an intermediate lamination and confined by adjacent laminations of said members, said strips extending over said beam from opposite sides thereof, and means for connecting the ends of said strips together.
