United States Patent 3,029,055 HANGER BLOCK CLAMPS FOR CASTABLE ROOF STRUCTURES Willard B, Smith, 64 Church St., Jackson, Uhio Filed Jan. 15, 1960, Ser. No. 2,763 3 Claims. (Cl. 248-228) This invention relates to new and useful improvements in hanger blocks for castable refractory materials and more particularly to the brackets or clamps for mounting the same.
It is among the objects of this invention to provide a tong-type hangar bracket for supporting refractory hanger blocks from I-beams or channels to form the roof of an industrial heating furnace or the like.
It is a further object of the invention to provide such a tong-shaped suspension member which shall be adapted to interlock with the flanges of the hanger blocks and I-beams to be adjustably mounted on the latter.
These and other objects of the invention will become more apparent from a consideration of the accompanying drawings constituting a part hereof in which like reference characters designate like parts and in which:
FIGURE 1 is an end elevational view, partially in section, of a portion of a hanger block and I-beam with the hanger block suspension bracket interlocked therewith;
FIGURE 2 is a side elevational view taken at right angles to the view of FIGURE 1;
FIGURE 3 an isometric view of the hanger block suspension bracket embodying the principles of this invention;
FIGURE 4 a top plan view showing the clamping bracket in its partially assembled position with one of the parts inserted through a slot in the other part and with its longitudinal axis disposed 90 from the axis of said other part;
FIGURE 5 a view in perspective of a hanger block; and,
FIGURE 6 a vertical section elevational view diagrammatically illustrating a roof structure made of a castable refractory material.
With reference to FIGURE 6 of the drawing, the numeral 1 generally designates a monolithic roof made of a castable refractory material made of calcine clay and conglomerate, together with a binder such as water or a sodium silicate solution, the entire monolithic roof being suspended from I-bearns 2 that constitute the superstructure of the roof. In building such castable roof sections, hanger blocks such as the block 3 are suspended from the I-beams 2 by clamping brackets generally designated by the numeral 4. The hanger blocks 3 are provided with grooves 5 that form flanges on which the castable roof material is supported.
The present invention deals with an improved form of hanger bracket 4 which is shown in FIGURES 1, 2 and 3 of the drawing and which consists of a pair of steel strips designated by the numerals 6 and 7 having oppositely disposed flanges 8 and 9 and 10 and 11, respectively. The member 6 is provided with a slot 12 of a size to permit the insertion of the flange 10 of the strip member 7, as shown in FIGURE 4 of the drawing and slot 12 is of a width that will permit turning the member 7 90 from the position shown in FIGURE 4, as indicated by the arrow to bring the flanges 8 and 10 in alignment in the manner shown in FIGURE 3 of the draw- 3,029,055 Patented Apr. 10, 1962 ing. In this position, the flanges 9 and 11 are also in alignment for engaging the top flange 13 of the hanger block in the manner shown in FIGURE 1 of the drawing. The wide flanges 8 and 10 engage the oppositely disposed flanges 14 and 15 of the I-beam 2, as shown in FIGURES l and 2, to effect an interlocking engagement of the hanger block 3 with the I-beam 2.
The advantage of the interlocked type of hanger block clamp is apparent from the fact that it allows adjustment of the block on the I'beams 2 to either stagger the blocks on one I-beam or maintain alignment thereof with the blocks on adjacent I-beams, there being a closely spaced series of blocks in each of the rows of blocks, as viewed in FIGURE 6 of the drawing.
As shown in FIGURE 4, a filet 16 is provided on the flanges 11 and 9 to engage the side of the hanger block 3 in the manner shown in FIGURES 1 and 2.
The interlocked construction of the strips 6 and 7 allows for replacement in case of repairs; that is to say, if one of the hanger blocks is broken out of a wall, a new clamping bracket can be inserted in place without sliding it from the end of the I-beam, as would be necessary if the parts were not insertable in the manner demonstrated in connection with FIGURE 4 of the drawing.
Although one form of hanger block has been disclosed, it is apparent that any shape of hanger block can be employed with the clamps as long as they have a flange portion 13 for engaging the flange elements 9 and 11 of the clamping bracket.
Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the prinicples herein set forth.
I claim:
1. A clamp for supporting hanger blocks for castable roof structures comprising a pair of substantially S-shape disjointed tongs having flanges at one end for engaging oppositely disposed shoulders of a hanger block and having flanges at their other ends for engaging the horizontal extending flanges of an I-beam, said tongs having strap-like body portions one of which is wide and slotted and the other is relatively narrow and of a width to fit into the slot of said first-named tong the length of the slot being greater than the width of the tong ends to allow for the insertion of said ends into said slot and turn the same to effect interlocking engagement of said flanges with their respective blocks and I-beams.
2. Hanger block clamps as set forth in claim 1 in which the flanges on opposite ends of the tongs are inverted so that pressure on the bottom flanges will urge the top flanges into clamping engagement with the I-beam flanges.
3. A clamp as set forth in claim 1 in which the bottom clamps are provided with projecting lugs for engaging opposite faces of said hanger blocks.
