MARCIAN E. SAUNIER, OF BAY CITY, MKCHIGAN.
Application filed April 23, 1924. ficrial No. 708,397.
of Bay and State o'l Michigan, have invented certain newand useful Improve ments in Hooks, of which the following is a specification.
This invention relates to hook supports and the like, and particularly to a hook for use in supporting forms from beams, girders, or other structural members, and into which concrete is poured.
()ne object of the invention is to design a very simple, and substantial hook for supporting forms and the like from steel work, and which can also be used for hanging and supporting a monorail system, mechanical equipment, piping, permanent or temporary balcony, or in fact any weight. or object which it is desired to suspend from a beam or ceiling.
Another object is to provide a form support from which the bolts can be removed after the concrete is set, so that a clean opening remains which can be neatly and easily pointed up, and which leaves no exposed metalparts to form'rust spots, etc.
A further object is to provide form supports adapted to engage the flanges of the structural members, one on each side, and means whereby they can be tied together to prevent displacement due to a suspended weight or when the concrete is being poured.
lVith the above and other objects in View, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and particular ly pointed out in the appended claims, it being understood that changes may be made in the form, sizes, proportion and minor details of construction without departing from the spirit, or sacrificing any of the advantages of the invention.
In the drawings:
Fig. 1 is a side view otmy improved hook showing a bolt in position therein.
Fig. 2 is an edge view thereof.
Fig. 3 is a central vertical sectional view of the hanger only. i
Fig. 4: is a top plan view thereo'hand Fig. 5 is a bottom view.
Fig. 6 is a vertical cross "iew 01" a large standard I-beam, illustrating the hooks used for supporting a form for concrete work.
Fig. 7 is'a view showin the hooks proper in place on a small I-beam cast in the concrete, another pair othooks being placed on the lower end of the bolts, and engaging an I-beam serving as a part oi a monorail system.
Fig. 8 is a view similar to Fig. 6 show ing a section of I-beam with an extra heavy flange, the hooks supporting a pipe and a balcony.
In construction work in general itis customary to use shoring to support the forms into which the concrete is poured, this is both expensive and inconvenient, as the shores must; be very numerous and considerable wedging must be done to make the job accurate and true, and these shores ohstruct and hinder the workman and mustremain in position until the concrete is set, also, the shoringmust be cut to predetermined lengths, and when once used, may not lit the next job, further, when the concrete is set, there is no "opening or attaching means for simporting any, mechanical equipment, unless especially provided for,
these disagreeable features it have overcome in my improved construction which leaves a tree clear space, automatically provides supports and leaves a smooth finished job, as the entire dead load is on the beam while where the concrete is green and little or no deflection occurs after the con' crete is set. v
Referring now particularly to the drawings in which I have shown the preferred embodiment of my invention, the numeral 5 indicates the hook or support, which is formed as clearly shown in Figs. 1, 2 and 3 of the drawings, being provided with jaws 6 adapted to engage the flange of an I--bea1n or other structural member, the head 6 being rounded and is formed with spaced apart ribs 7, adapted to receive a nut 8 between them, a vertically disposed opening 9 extends through this head and spaced apart hook shaped legs 10 are formed integral therewith, extending downwardly and converging at their lower ends.
It will be noted that the shape of the member is such that when it is in engagement with the flange or other structural member it will have a two point bearing thereon. the jaw engaging the upper surface, while the lower end enga the under side of the beam, the bolt 12 euending sphstantially vertical. In form work these llt) supports are used in pairs and numerous enough to support the form and are adapted to be connected by means of a strand of wire 13 passed around the rounded section 14 between the legs and then twisted tight as shown, this provides a very sim ple and economical. method of fastening, and any width or section of beam can be accommodated.
I wish to direct attention to the tact that the hook is appliable to any beam or girder, and in Figs. 6, 7 and S I have illustrated a large, small, and thick girder, and it will be obvious that the hook will assume slightly different positions, when applied to tl ese different sized and proportioned members, the opening 9 is therefor made large and the head rounded so that proper bearing may be provided for the bolt nut in any required position, these ribs being spaced to allow the nut to rest therebetween, the adjusting being accomplished by turning the head of the bolt, this makes an ideal adjustment and eliminates the wedges and blocks together with the labor and material involved in the shaping thereof.
In Figure 6 I have shown a sectional tragmentary view of a form l t into which concrete is poured, this form being supported by the hooks secured together by the strands of wire which are twisted until proper tension is secured. The bolts 12 first greased and then inserted through the soliit planks 15, bed blocks 16, and washer 17 Pairs of these supports are spaced along the beam at predetermined distances and a block of proper thickness is then inserted between the underside of the beam and the form, and each pair of bolts adjusted by means of a wrench applied to the head thereo't, when the adjustment is completed the concrete is poured into the term, and when set, the wrench is again applied to the heads of the bolts and they are then backed out of the form to be again used, or can be reinserted in position for supporting mechanical equipment, pipes, balconies, etc., as indicated in Figs. 7 and S, the supports proper, together with the nut remaining in the concrete and in engagement with the beam.
In Fig. 7 the supports are shown set in the concrete, and again assume a different angle due to the size of the beam, the bolt bearing and points of contact with the beam are howeier always the same, the opening and rounded head permitting the bolt to be accommodated at these various angles, in this instance an Z-eam is suspended from a second pair of supports secured on the lower ends of the bolts. and this E-beam can be used as a monorail system or the like.
Fig. 8 illustrates the hanging of pipe lines, and the hook used as a support tor a balcony.
From the foregoing description it will be obvious that I have perfected a very simple, substantial and economical hook for attaching to the flanges of the I-beams or other structural members for supporting forms, mechanical equipment, and various members therefrom.
What I claim is l. A hook adapted to engage the flange oil? a structural member and having a two point contact therewith, a head on the hook adapted to engage the inside ot the flange ot the structural member, a vertically disposed opening through the head and a bolt removably mounted therein.
2. A hook provided with a jaw and adapted to engage the flange of a structural memher and formed with a curved head, spaced apart legs formed integral therewith and engaging the bottom ot the structural member, and an opening through the head adapted to accommodate a bolt at various angles.
3. A hook formed with a jaw adapted to engage the flange of a structural member and having a curved head formed with spaced apart raised ribs adapted to receive a nut between them, and a pair of legs depending from said head and adapted to engage the underside of the structural member.
l. A hook support formed with a jaw adapted to engage the flange of a str ctural member, and having a curved head formed with spaced apart ribs adapted to receive a nut between them, legs depending from and formed integral with the head, and adapted to engage the underside of the structural member, and an opening through the head adapted to accommodate a bolt at various angles.
5. A hook support formed with. a jaw adapted to engage the flange ot a structural member, and having a curved head "formed with spaced apart ribs legs depending from said head and adapted to engage the underside of the structural member, and a rounded connecting wall connecting said legs.
6. The combination with a structural member, of a pair or" hooks adapted to engage opposite edges thereof, said hooks being formed with curved heads having legs depending 'heretrom, and flexible means for securing the hooks together.
7. The combination with a striu-tural member, out a pair of supports adapted to engage opposite sides thereof, said hooks being formed with a jaw and a curved head, legs depending from the head and connected together at their lower end, a vertically disposed opening through the head and adapted to receive a. bolt and flexible means for seeming the hooks together.
8. The combination with a structural member, of a pair of hooks adapted to enopposite sides thereof. said hooks haw ing jaws, a curved head having spaced apart ribs thereon, spaced apart legs depending from said head and engaging the underside of the structural member, oonneeting Wall between the legs, and flexible means engaging said Walls for tying the hooks together.
9. The combination with a supporting member, of a pair of hooks adapted to e11- gage the opposite sides thereof, said hooks being formed With curved heads terminating in a jaw, an opening through said head, spaced apart legs depending therefrom, a 10 Wall connecting the legs together at the free ends thereof, and flexible means for engaging said Wall for securing the hooks together.
