Definitions

  • the suspension may be effected in various ways, one of these comprising hanging bricks (commonly known as hanger bricks) on steel girders of I or T section at intervals and ramming or casting the roof or other structure around the lower parts of these bricks.
  • FIGURE 1 being an elevation partly in section
  • FIGURE 2 a section on the line IIII in FIGURE 1.
  • FIGURES 3, 4 and of the accompanying drawings Part of one brick according to the invention is shown in FIGURES 3, 4 and of the accompanying drawings, FIGURE 3 being a side elevation, FIGURE 4 being an end elevation looking in the direction of the arrows IV in FIGURE 3, and FIGURE 5 being a section on the line VV in FIGURE 3; and part of another brick is shown in similar FIGURES 6, 7 and 8.
  • a monolithic furnace roof 1 is to be supported from steel girders, one of which is shown at 2.
  • Hanger bricks one of which is shown at 3, are suspended frirn each girder 2, and except for their upper parts are embedded in the roof 1, which is actually forrned around them.
  • the connection between the girder 2 and each brick 3 consists of a pair of clips 4 and 5 of U-shape.
  • Recesses 6 and 7 are formed in the end faces of the brick at a little distance below the top so as to leave flanges 8 and 9 above the recesses.
  • the clips 4 and 5 are of such dimensions that each will fit over the top of the brick with its arms extending along opposite side faces and its base in one of the end recesses 6 and 7. As shown, one arm 4 of the clip 4 is in contact with a side face of the brick and the base 4" of this clip bears against the underside of the flange 8. An arm 5' of the clip 5 crosses the arm 4' and so is out of contact with the side face of the brick, while the base 5" of this clip bears against the underside of the flange 9. On the opposite side face the relative position of the other arms 4" and 5" of the clips 4 and 5 is reversed, the arm 4" being outside the arm 5".
  • Each arm is bent to form a hook.
  • the action of the clips is thus of a scissors nature, and so long as the weight of the roof is pulling each clip downwards the tendency is for the hook ends to move towards one another.
  • the number and position of the recesses may vary, the minimum being two recesses, one for an arm of each clip. If there are only two recesses they are preferably made at diagonally opposite corners of the brick.
  • all the clips should be identical in size and shape. Identical clips can be used even if two recesses are not made at diagonally opposite corners of the brick, since both recesses may be in one side face if one recess is made deeper than the other.
  • each pair of diagonally opposite recesses being deeper than the other pair, to provide four ledges for the arms of the two clips.
  • all the clips may be of the same size and shape, and none will extend outwards beyond either side face if the depth of the deeper recesses is at least equal to twice the thickness of the arms of the clips.
  • each ledge is less than that of the corresponding clip, so that some downward rocking movement of the clip can take place before the arm bears firmly against the ledge.
  • each clip which are commonly made of mild or stainless steel rod, are such that each clip will fit over the recessed part of the top of the brick with slight clearance, and then on one side face of the brick an arm 4' of the clip lies substantially in the recess 11 and can make contact with the ledge 13, while the intersecting arm 5 of the other clip 5 lies outside the arm 4' but in contact with it.
  • the arm 'of the clip 5 lies in the recess 12 and the arm of the clip 4 is outside the arm of the clip 5.
  • FIGURES 6 to 8 The preferred construction is shown in FIGURES 6 to 8. Here there are recesses across all four corners, one pair of diagonally opposite recesses 15 and 16 being deeper than the other pair 17 and 18.
  • the arm 4' can bear against the ledge 19 formed by the base of the recess 15 and the opposite arm of the clip 4 against the ledge formed 'by the base of the recess 17.
  • the arm 5 of the other clip lies outside the arm 4' and can bear against the ledge 20 formed by the base of the recess 18, and the other arm of this clip can bear against the ledge formed by the base of the recess 16. It will be seen that two identical clips can be used and all four arms are given support.
  • a hanger brick with a rectangular head presenting side and end faces, said end faces being formed with recesses to receive the bases of U-shaped clips, the arms of which extend along the side wall and terminate in hooks,
  • said brick being formed with two further recesses each made in a side face across an upper corner from each end recess to the top of the brick to form an inclined ledge to support an arm of a clip.
  • a brick according to claim 1 in which there are two recesses at diagonally opposite corners of the head of the brick.
  • a brick according to claim 1 in which there are recesses across all four corners, one pair of diagonally opposite recesses being deeper than the other pair, to pro- 10 vide four ledges for the arms of the two clips.
