  • Yet another object of the invention is to make optimum use of related suspension apparatus components by advantageously dissipating displacement forces therein in shear as will become hereinafter apparent.
  • Still a further object of the invention is to employ vertical suspension components in such a manner that they provide horizontal reaction components for improving associated safety factors.
  • Another object of the invention is to make hanger structures slip and failure proof.

  • a still further object of the invention is to achieve with the use of pins an assurance against failure which is not normally achieved by the use of steel concrete inserts which the pins replace.
  • Yet another object of the invention is to provide means for effectively putting concrete structures and the like in compression to improve the load supporting characteristics thereof.
  • the invention contemplates a technique whereby a hanger bracket or the like is fastened to an overhead structure by such means that the tendency of the bracket to be pulled away from the overhead structure by a load on said bracket is resolved into vertical and horizontal forces, the latter of which is applied to a vertical member or the like in shear so that an optimum resistance to displacement of the bracket is provided.
  • the aforenoted horizontal force is transmitted to the vertical member through the intermediary of the bracket itself.
  • the transmission of the horizontal force may be effected through a member which is physically separate from the bracket.
  • a supplemental member for transmitting at least a part of this horizontal force and this supplemental member may, according to a particular embodiment of the invention, be employed to further hold a fastening member in place, as will become hereinafter apparent.
  • the invention contemplates preferably the use of one or more inclined pins or like fastening members whereby the resolving of load forces into its horizontal and its vertical components may be readily accomplished and,
  • a special means can be provided for putting masonry structure into compression whereby the strength of the structure and resistance to fracture or deterioration is greatly improved.

  • FIG. 1 The purpose of the structure illustrated in FIG. 1 is to provide means for suspending a load (not shown) from an overhead masonry structure 20 which may be constituted by concrete or the like.
  • the fastening elements of this embodiment do not pass completely through the overhead structure 20, al though this is a possibility, if necessary.
  • the fact that the fastening elements do not pass completely through overhead structure 20 clearly facilitates locating the hanger arrangement in that it is unnecessary to drill through structure 20 from above whereby the need for repairing the upper surface of structure 20, which may constitute a floor, is avoided.
  • element 10 is a knee bracket fabricated of steel, or a like metal having suitable strength, element 10 comprising a horizontal arm 22 and a vertical arm 24, said arms being perpendicularly related and defining an angle of therebetween.

  • a nut 132 is threadably engaged on the lower extremity of bolt 124 and urges disc 126 outwardly against heads 11%) and 112.
  • the disc 126 resists axial displacement of pins 106 and 1418 downwardly out of bores 102 and 1114, each pin acting in opposition to displacement of the other of said pins.
  • bolt 124 constitutes a vertical element to which the horizontal vectors of the downward movement of pins 166 and 1198 are applied perpendicularly or in shear.
  • a load supporting member (not shown) can be threadably afiixed to the lower extremity of bolt 124.

  • sleeves 146 and 148 can be omitted in which event plate 144 acts as the fulcra. If the holes in the plate are one thirty-second of an inch larger than the pins 144 and 142, suflicient compression results.
  • pins 140 and 142 Due to this pivoting tendency of pins 140 and 142, the inner extremities of said pins accommodated within the masonry structure act to compress the masonry structure thereby greatly increasing the effectiveness thereof.
  • the disc 152 is in the shape of an inverted truncated cone, the peripheral surface of which inclines at an angle corresponding to the side surfaces of the pins 141) and 142.
  • Surfaces 154 and 156 of disc 152 are arranged at an angle of about 22 /2 to the horizontal in order to correspond with the free extremities of the inclined pins.
