It is widely used as a fireproof insulation wall. Since it is lightweight and flexible, it is difficult to construct the furnace wall by itself.
The method usually used is to fix it to the furnace shell using studs made of heat-resistant alloys, or to attach modules made by stacking strips cut out from the blanket in the thickness direction to the furnace wall with adhesive, etc. It had been.
Furthermore, since ceramic fiber is glassy, it tends to crystallize when exposed to high temperatures, causing shrinkage of several percent. As a result, cracks occur on the wall surface and partial peeling occurs. This tendency is also a phenomenon observed in the above-mentioned module.

The strips having protrusions alternately at intervals are juxtaposed in the vertical and horizontal directions, and each protrusion fits into a recess formed by the juxtaposed strips. It has a combined structure.

る。 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a strip cut out from a ceramic fiber blanket, and a protrusion 2 is formed on one side of the strip. Reference numeral 3 in FIG. 2 is a strip obtained in the same manner, which has protrusions 4, 4' alternately on both sides. Strip 1 is shown in FIGS. 3, 4 and 5 of the embodiment.
As shown in the figure, two pieces are arranged in pairs in the vertical direction so that the protrusion side 2 and the back side 2' face each other.
On the other hand, the strips 3 in FIG. 2 are arranged in pairs in the horizontal direction, but since there are recesses formed by the two vertical strips 1 on the front and back sides, Every two strips 3 are juxtaposed so that the protruding portions of the strips 3 fit therein. In this case, the protrusions 2 of the strip 1 are fitted into the recesses of the strip 3, respectively.

ないという効果を奏するものである。 Since the shape of the module of the present invention is as described above, when exposed to high temperatures, the shrinkage of the module in the thickness direction is the same as that of the conventional module, but the shrinkage in the planar direction is such that each strip alternates. Since the structure is intricate, the shrinkage is suppressed, and therefore, there is an effect that almost no shrinkage in the surface direction of the module as a whole is observed.
従つて、このモジユールを炉壁に接着剤によつ

壁面に亀裂が生ずることがほとんど認められな
い。 Therefore, when this module is attached to the furnace wall with an adhesive or a metal jig, there is hardly any cracking on the wall surface.

ているという効果もある。 In addition, in the module shaped according to the present invention, the portion of each strip that faces the inside of the furnace is small due to its structure, so the area affected by heat shrinkage is reduced, and each protrusion has a portion that fits into each recess. Since it forms a small amount of voids, it also has the effect of increasing its insulation properties.

とができる。 In the embodiments of the present invention, strips having the shape shown in the figures were used, but at least one strip had a protrusion on one side, and the other strips had protrusions on both sides. In particular, it is necessary that each strip has a structure such that its contraction is suppressed by the fitted state of the protrusion and the recess. The number of protruding parts and recessed parts of the strip, the number of pairs, the thickness of the strip, etc. can be set arbitrarily.
