2 Claims. (Cl. 72--28) as such material is expanded and contracted through temperature changes.
Another object of my invention is to provide, in connection with heat-insulating blocks or slabs, means for maintaining uniformityof spacing between the slabs, and
resisting shifting of such slabs relative to one another to such extent as will result in excessively wide spaces between their opposedl edges.
As shown in the accompanying drawings, Figure 1 is a perspective view showing one form of the invention in a partially completed structure;

Fig. 12 is a view showing a manner in which two corrugated spacers may be used together;
Fig. 13 is a horizontal sectional View through a joint, having two of the spacers of Fig. 12, and
Fig. 14 is a fragmentary view of a spacing strip wherein the cormgations extend longitudinally of the joint instead of vertically as in Fig. 8.
My joint structure is adapted for use in connection with insulating bricks or slabs 15 of conventional form that are applied to the exterior surfaces of containers or other bodies that are to be heat insulated. Owing to the wide ranges of expansion and contraction, calking or iilling material interposed between opposed edges of blocks of this character will not maintain a close tit with the edges or side walls of the blocks, under repeated temperature United States Patent O changes. Also, the blocks will sometimes shift relative to one another, so that there will be non-uniform spacing between the blocks with consequent excessive spaces and ruptured or weakened joints at some locations.
Instead of simply placing calking material within and overlying the joint, I provide a metal joint structure that will not only maintain the blocks in approximately their original relative positions, but will more effectively seal the joints and prevent forming `of cracks or iissures that would allow escape of heat.
When the blocks 15 are placed in position upon a con- 4tainer or the like that is to be insulated, their opposed edges are spaced apart slightly to permit of expansion without buckling.
As shown in Figs. 1 and 8, my device comprises a sheet metal cap strip 16 bent to bead form at 17 and aligning pins 18 snugly tting within these beads for telescopic connection with beads of adjacent strips, to maintain them in alignment. Additional folds or bends 19 are provided in the strip and have wing-like extensions 20v that are of foraminous or mesh form. They may simply constitute extensions of the body portion of the strip slitted and stretched as expanded metal or may have numerous holes punched therethrough, or be of other mesh-like material welded to the edges of the body portion of the strip, these Wings being embedded in plastic insulation covering 21 as shown more clearly in Fig. 8.
A corrugated strip 22 of springy sheet metal has an upper approximately-straight flange 23 that is welded to or simply extends into the strips, between the bends 19. Since the blocks 15 are of porous or relatively soft material, staples 24 can be driven through the wings 20 to hold the strips and blocks in place for the application of the covering 21 of plastic material. Y
The ange 23 is secured to the strip 22 at the crests of the corrugations on one side of the strip, by welding or otherwise. While compression of the corrugated strip through expansion of the blocks 15 tends to elongate the strip and this tendency to elongation is resisted somewhat by the ange 23, the corrugations can nevertheless be compressed somewhat toward a ilattened shape or to flex somewhat, because their crests at one side of the strip are free of any rigid connections to a straight strip.
Shifting of the blocks 15 under temperature changes will be yieldably resisted by the corrugated strips 22, and such strips will tend to move each block back to its original position during a cooling period. The beaded portions of the strip 16 will, of course, expand and contract, and because of the embedment of their wing portions by the plastic 21, they will prevent leakage into the spaces between the blocks 15.
Along a straight-line seam, the strips 16 will, of course, be placed in end-to-end relation with the pins 18 telescoping into the beads 17 of adjacent strips. At the corners of the blocks, sealing members 16 have to extend in directions at right angles to one another, and therefore, the edges of the Wings 20 are mitered as indicated at 26, so as to get a good t at these joints.
Where joints intersect one another as in Figs. 6 and 7, the pins 18 in a joint strip lying in one direction will extend through the side of a cap strip that extends at right angles thereto or into the hollow bead of such a strip, to maintain alignment of the sealing strips at such joints.
Referring now to Figs. 2, 3 and 4, I show a tank 30 that has an insulating covering 31 in the form of arcuate slabs. Provision for expansion and contraction at the joints between the slabs is made by using a cap strip 32 having a central hollow bead 33, smaller beads or folds 34 and wings 35. Spacing strips 36 of corrugated form are welded at their upper edges to the cap strips 32 and have their body portions corrugated as in the case of the strips 22 of Fig. 8.
. Y 2,853,871 i n Cover strips 37 are placed in overlying relation to the cap strips 32 and are connected at their edges to the pipe covering material by screws 38 that also extend through the wings 35 of the cap strip.
Referring now to Fig. 9, I show an arrangement that is particularly suitable for sealing the corners where walls meet one another at right angles and where no corrugated spacing` strip corresponding to the corrugations 22 is used. In this case, a sealing strip 40 has an enlarged central hollow bead, with laps or folds at 41 which, in turn, have mesh-like wings 42 that can be bent at right angles to each other and be embedded in the plaster or cement of adjoining slabs at the corner of a structure, and the strip 40-41 will have ample expansive and contractive ranges and thereby maintain a seal at the corner where the slabs meet.
In Fig. 10, I show a pipe or conduit 43 covered by an insulating sleeve 44 and blocks 45. In this case, sheet metal sealing strips 46 are employed at the various joints, with wing portions overlying the outer faces of the blocks 45, and their grooved or channeled portions corrugated as shown at 47, so that they will maintain close fit with the blocks 45 under expansion and contraction. A covering sleeve of asbestos or other suitable material surrounds the sealing strips 46.
In Fig. 11, I show a joint wherein a cap strip 50 has lateral folds or pleats 51 and wing portions 52 as in Fig. 9.
`In this case however, a corrugated spacer strip S3 is employed, of the form shown in Figs. 1 to 8, to maintain uniformity of spacing between the blocks 54 at the various joints throughout a complete structure, and to also assist in maintaining the cap strip in proper relation to the blocks with which it is employed.
In Figs. l2 and 13, I show a pair of strips 55 such as the strip 22--23 used in connection with one another, in a single cap strip, to which their flanges 56 are welded. This arrangement permits of greater expansion and contraction movements of the blocks or slabs 57 relative to each other, Without the necessity of using a deeply corrugated single strip.
Referring now to Fig. 14, I show a spacing strip having a flange portion 58 for welded connection to a cap strip such as the strip 16. In this case however, the body por tion of the spacing strip has corrugations 59 that extend longitudinally of the space between the slabs instead of perpendicularly to the plane of the slabs as is the case of Fig. 8.
I claim as my invention:
l. A wall structure which is subjected on the inner side thereof to temperature changes substantially higher than those resulting from atmospheric changes, said structure comprising an inner base member and an insulating covering on the outer side of said base member, said covering including a plurality of preformed slabs of insulating material slidably supported on said base, the adjacent edges of adjacent slabs being spaced apart to compensate for the expansion and contraction in said covering, resilient and flexible metallic strips disposed between the slab edges and extending the length of the slabs, each strip being corrugated throughout its length with the axes of the corrugations extending transversely of the length of the strips, the edges of adjacent slabs abutting the crests of the corrugation on the opposite sides of the strip, each strip extending from said base to substantially the outer surfaces of said slabs, an outwardly projecting ange secured to the outer edge of each strip at the crests of the corrugations on one side of the strip and projecting beyond the outer surfaces of said slabs, metal cap strips covering the spaces between adjacent slabs and overlying the corrugated strip, each cap strip including a substantially .circular medial rib and integral wing portions on opposite sides of the medial rib, said rib having an access slot opening toward the spaces between adjacent slabs, said wing portions overlying the outer surfaces of adjacent slabs and being secured thereto, said outwardly projecting flanges extending through said slots and disposed within said medial ribs, a cementitious insulating layer covering the outer faces of said slabs, whereby upon expansion of said slabs said corrugated strips are compressed and upon contraction of said slabs the corrugated strips tend to shift said slabs during the cooling thereof.
2.l A wall structure as recited in claim 1 with each cap strip wing portion including a corrugated section therein adjacent the rib, the axes of the corrugations of the Wing portions extending parallel with the axis of the circular ribs.
