Like parts are indicated by similar characters of reference throughout the several views.

Referring to the accompanying drawings, 1 is a structural beam of the skeleton building` structure which is to be encased in concrete as indicated at 2. Enclosing the structural beam 1 is a sofiit form comprising the bottom portion 3 and sides 4 which are supported at intervals upon transverse cleats 5.

In order to support this form While the concrete 2 is being deposited therein and until the latter is set or hardened, the form structure is suspended from the structural beam 1. The provision of a suitable hanger for this purpose is the dominant purpose of the present invention. In the present disclosure, hangers for the concrete form are shown engaged With the opposite margins of the supporting beam flange. These hangers may be oppositely disposed relative to each other or may be staggered throughout the length of the form as may be found most suitable, and in accordance With the size and Weight of the form and concrete deposit 2.

Each of the form hangers comprises a hanger bolt 6 upon which are slidingly mounted two telescopic

tubular members

7 and 8. In the construction shown in Figs.

'1 to 4 inclusive, the tubular member 8 is enclosed within the member 7. The member 7 is provided with a laterally extending jaw 9 which overhangs the fiange of the beam 1 while the relatively reciprocat-ory member 8 is provided with a complementary jaw 1() engageable with the under side of the beam 1 and coacting with the j aw 9 to grip such beam flange. The tubular member 7 is longitudinally slotted at 11 to accommodate the jaw 10 of the member 8. rIhe member 8 is of such length as to serve as a spacer or spreader which predetermines the thickness of the deposit of concrete intermediate the underside of the beam 1 and the bottom of the form. This tubular member 8 abuts at its lower end upon the inner face of the bottom of the form 2, While its laterally projecting j aw 10 abuts upon the under side of the beam. A nut 12 for the hanger bolt 6 engages With the upper end of the tubular member 7 and as the bolt 6 is tightened relative to such nut, the parts are drawn into clamping engagement with each other. By tightening the bolt 6 relative to the nut 12, the bottom ,2 of

the form is drawn upwardly against the spacer member 8, the aW 10 of which is thus forced against the flange of the beam 1 While at the same time the member7 is retracted downwardly drawing its jaw 9 into firm gripping engagement with the upper side of the beam flange. Thus the beam fiange is securely gripped between the jaws 9 and 10 and the concrete form is firmly clamped in its adjusted relation with the beam 1, its approach to which is limited by the interposed spacer member 8. To prevent the

members

7 and 8 from being rotated or twisted out of position during the adjustment of the hanger bolt @,the member 7 is provided with a. laterally ext-ending finger 13 abutting upon the margin of the fiange of the supporting beam and resisting rotary motion. After the concrete has been deposited and has set Within the form, the latter can be removed by unscrevving the hanger bolts 6 from the nuts 12 which are then embedded in the deposit 2 of concrete along` with the

hanger members

7 and 8. These parts are permanently embedded and may subsequently be employed for the attachment of extraneous bodies to the concrete structure. The embedded

members

7 and 8 not only afford secure anchorage for the nuts 12 but also provide a passage way through the concrete deposit to such nut 12 through which an attachment bolt may be subsequent-ly introduced for attaching a structure such as a line shaft hanger or the like to the building structure.

In Fig. 5 there is shown a modification wherein the relation of the

members

7 and 8 is reversed. In this form of device, the tubular member 7 carrying the jaw 9 is dis` posed interiorly of the member 8 which carries the complemrntary jaw 10. The function and application of the members are the same as before described.

Vvlhile the form of hanger members illustrated in Figs. 1 to 5 inclusive are especiallyy adapted to be formed as metallic castings, the preferable construction is that illustrated in Figs. 6 to 10 inclusive, wherein such members are formed from sheet metal stampings. For such method of manufacture the spacer member 8 is preferably oisposed exteriorly of the member 7 in the manner shown in Fig. 5 and in subsequent figures of the drawing. In such sheet metal or stamped construction, the tubular member 7 is preferably not exactly cylindrical in cross sectional form in order that the exteriorly disposed tubular member 8 telescepically adjustable thereon may not be capable of rotary motion. The overhanging jaw 9 in such construction comprises parallel Wings formed integral with the tubular portion of the member 7 and projecting therefrom for'overhanging engagement with the flange of the structural beam 1. Such stamped metal jaw portion 9 is preferably though notnecessarily formed with indentaf members:areeincapable of relativel rota-ry moe.

tion of theimember 7 from sheet metal,f. the f nut 121is. inserted-.Within the partially formed member` and thel Wallsthereof contracted around thenut thereby ixedly embedding the nut within: the member at a midheight point. This affords a greater clearance space ,.Withinithelmember 7 above the nut 12 from Whichfconcrete ispexcludedby the-:top wall 16. Sucliclearance spa-ce facilitates the sub` sequent use of the embedded member and nutas an insert for attachment of other bodies to 4the concrete structure. The application and operation of the stamped member is as before described. The member 8 is duo-functional, serving both as a spacer and as a gripper memb,er.- The adjustment of the bolt 6 rela- ;tive to the nut 12 axiallyl adjusts the

members

7 and 8 to cause their jaws 9 and 10 to forcibly grip the flange of the beam 1 and at the same time the bolt fdraws the concrete form struc ture toward the `beam 1 until limited'by the @interposed spacery member 8 Where it is clamped by the tightening of such bolt 6.

The present construction not only firmly and securely supports the concrete form, but

it insures the proper spacing of the form relajtive to the structural beam to afford the required stratum of concrete deposit beneath the beam. It enables the form structure to be aligned by unsln'lled labor and Without the necessity ofV accurate measurement. Morellover, it supports the overhead form structure upon the skeleton frame of the building Without the necessity of struts and shores',` thusv leaving the space jbelow clear for carrying on other building operations. /Vhile its function `in supporting the form structure is of Withthe headfof the bolt to p-rerentrelative .70o` While the `hanger has been. shown'` and dez,y

The provision ofthe stoplugsorribs 14V enables the bolt to ben-tightened from` thebot-fr tom without danger'of' the nut turningrelaz=y tive to the hanger.
