March 14, 1939. G. P. REINTJES INSULATING REFRACTORY WALL Filed Dec. 28, 1956 lmventor,
I uttornegp Patented Mar. 14, 1939 UNITED STATES PATENT OFFICE 5 Claims.
This invention relates to insulating walls for furnaces whereby walls be constructed in integral panels comprising unit sheets or plates carrying light-weight insulating firebrick on their inner sides, the object of the invention being to provide a construction of this'general character in which the panel is provided with brick engaging members supporting the brick columns against downward and inward movement.
A further object of the invention is to provide a unit panel construction of the general character outlined, in which the vertical load may be transmitted by tile engaging castings carried by the panels on suitable horizontal members carried by the buckstays or uprights.
A still further object of the invention is to produce a construction of the general nature outlined which may be constructed almost entirely of common brick shapes, it being necessary only to present two corners of the highly friable insulating brick to a grinding wheel of any kind to form dovetail portions at With the general objects named in view and others as will hereinafter appear, the invention consists in certain novel and useful features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which:
Figure 1 is a fragmental perspective view of the wall of a furnace as it will appear with one form of the unit panel construction of the invention.
Figure 2 is a horizontal section taken through a fragment of the wall as it appears in Figure 1.
Figure 3 is a horizontal section taken through a panel construction accommodating the length of one brick.
Figure 4 is a cross section through a hanger forming a part of the invention.
Figure 5 is a perspective view of a common insulating fire brick as it will appear with two of its corners ground off to make a dovetail interlock so that it may be threaded into position as shown inFigures 1, 2 and 3.
Figures 6 and 7 are respectively perspective views of. modified forms of brick, one directly underlying a brick column and the other directly overlying a brick column.
In the said drawing, where like reference characters identify corresponding parts in all of the figures, I is an upright or buckstay, which, as common in furnace constructions, are spaced any desired distance apart, and
face of said uprights may be a series of vertithe corners, or, of course, the brick may be preformed of such shape.
secured to the inner cally spaced horizontally extending supports 2, shown in the present case as of T form. The stem of the Ts is secured by right angle clips 3 fastimed to the buckstays I in any suitable way. With such a construction, it will be evident that 5 the furnace skeleton will be divided .into horizontal belts by the supports 2. a
The wall proper, or the panel members, to fill in between the horizontals, comprises a plate member 4 having a pair of its side edges formed with inturned flanges 5 in the construction as shown, said flanges being on the vertical edges of the plate when positioned in a wall. The flanges are not coextensive with the vertical length of the plate, but are set back from the ends of said plate to leave straight or flat extensions 6 which are bolted or otherwise secured as by clamp bars 7 and eccentrics 83, illustrated in Figure l, to the horizontal supports. Bolted or otherwise secured to the flanges are reinforce castings 9, which are integrally formed with brick-engaging extension or lips iii, said castings being secured in such positions that the lips are inclined toward each other, so that they form dovetail portions (see Figure 3), engaging notches 25 ll cut out in the opposite corners of a brick l2 and thus prevent horizontal displacement of the brick.
The lower ends of the casting are provided with flanges 53 which underlie the lowermost brick and constitute a shelf or support for the overlying column threaded down between the lips I0. Of course, the sheets can be made of any desired width, and are not limited to one brick length as shownin Figure 3. In Figure 1, for example, the panel or sheet is ofv sulficient width to accommodate the length of two endwise abutting brick the abutting or adjacent brick ends, having their dovetail corners interlocked with the opposite flange M of a relatively U-shaped hanger i5 secured by bolts or otherwise, in the central vertical axis of the sheet, and having supporting flanges [5a at its lower end, as clearly apparent in the drawing. The bottoms of the casting may be so designed that the vert cal load may be transferred directly to the horizontal supports by the castings, to relieve the panel of as much load as possible, although, of course, a heavier panel could be used making such load transfer unnecessary or undesirable.
The space between superimposed panels bridg ing the vertical height of the horizontals may be provided with any suitable firebrick protection. In the construction here illustrated, the two topmost brick. are respectively a brick l6 and a brick H, to produce the stepped expansion joint l8. Resting on top of the brick I1 is a brick l9, which is not interlocked as here shown against inward horizontal movement. Resting on top of the brick i8 is one of the stepped brick I! which also is not locked against inward movement. A second stepped expansion joint is now provided by threading one of the brick I6 on the castings of the superposed plate for cooperation with the brick I'I.
With a construction of the type shown, it will be evident that the brick may be placed in threaded position, if desired, even before the panel is elevated. The panel is placed in position from outside the combustion chamber, preferably by bringing the lower ends of. the castings into rocking engagement with the horizontal support, the projecting flanges 6 of the plates resting against the outer face of the T-head of such supports. The panel may now be rocked to throw its upper flange portion into contact with the outerside of the immediately overlying horizontal. The panel may now be secured in position by the means above described, or by bolts, or otherwise, as found most convenient or desirable.
If the panel is of the double width as shown in Figure l, the space between. the oppositely extending flanges or lips of the center casting, is preferably packed with insulating material I9a before the brick are placed in position on. the panel. Suitable insulating lining 20 may also be placed between'the flanges and between the plates and the outer sides of the brick, if desired.
The vertical edges of adjacent panels are spaced apart any desired distance depending on the exact proportions of the, dovetail parts, and then the space or vertical extending pocket thus formed between panels, may be packed with any suitable insulating material 2|. The gap is finally closed from outside the furnace wall by batten strips, 22, secured by self-threading bolts or the like, tapped into the edges of the panels as illustrated.
It will be apparent from the above description that any damaged panel may be quickly and easily removed as a unit from any part of a furnace wall for repair of flrebrick. Or, if desired, any entirely new panel may be swung into the gap opened by the removal of a panel, without any material difiiculty or complicated maneuvering with a resultant loss of time or expense.
From the above description it will be apparent that I have produced a construction embodying all of the features of advantage set forth as desirable; and while I have described and illustrated the preferred embodiments, it is to be understood that I reserve the right tomake all changes within the spirit of the invention and without the ambit of the prior art.
