摩耗されて耐摩耗板の脱落事故を招来する。 Baffle plates, damper blades, etc. provided inside a duct, etc. for processing dust-containing gas etc. are subject to abrasion from both sides by dust. For this reason, although it is desirable to attach wear-resistant plates to both sides of the baffle plate or the like (covered object), conventionally there is no effective attachment means, and metal plates or the like are used as they are. Even if it were to be attached with an adhesive, there is no effective adhesive that can be used at temperatures above 200℃ among the adhesives that can commonly bond to metals and refractories, and even if it is fixed with bolts and nuts, the tightening force would be excessive. This can cause the wear-resistant plate to crack, or the heads of bolts and nuts can be easily worn, leading to an accident in which the wear-resistant plate falls off.
そこで、本発明は、耐摩耗板の破損を防止し、
耐摩耗板に所定の押圧力を付与し、かつボルトお

る。 Therefore, the present invention prevents damage to the wear-resistant plate,
The object of the present invention is to provide a bonding structure for wear-resistant plates that can apply a predetermined pressing force to the wear-resistant plates and prevent the heads of bolts and nuts from being worn out.

In order to apply the required pressing force to both wear-resistant plates and attach them to the adherend, the stepped holes of each wear-resistant plate and the mounting hole of the adherend are provided. It has a structure consisting of a bolt and nut that are inserted and screwed together so that their heads are at a predetermined distance from each other, and a wear-resistant lid that fills the recess of each stepped hole.

段付孔２の凹部に埋め込まれている。 In FIGS. 1 and 2, reference numeral 1 denotes a wear-resistant plate having a stepped hole 2 formed approximately in the center, and is made of alumina or silicon carbide. Reference numeral 3 denotes a covered body with mounting holes 6, and an inorganic fibrous elastic body 5 made of ceramic fiber, rock wool, etc. is interposed on both surfaces 4, 4' of the covered body 3, and the above-mentioned wear-resistant plate is attached. 1 are in contact with each other. Both wear-resistant plates 1 are attached to the adherend 3 by bolts 7 and nuts 8 that are inserted into the respective stepped holes 2 and the mounting holes 6 of the adherend 3 and screwed together. has been done. Bolts 7 and nuts 8 have stepped holes 2 in their respective wear-resistant plates 1.
Head portions 7' and 8' that fit into the recesses of the screws and a stopper portion 10 that prevents the mutual screw engagement from proceeding beyond a certain position are provided. Then, with the bolt 7 and nut 8 prevented from being screwed into each other by the stopper part 10, and with a predetermined distance between their heads 7' and 8', each elastic plate 5 is compressed and , a required pressing force is applied to each wear-resistant plate 1.
9 and 9' are wear-resistant covers made of almost the same material as the wear-resistant plate 1, and heat-resistant adhesive is used to protect the heads 7' and 8' of the bolts 7 and nuts 8 from dust. It is embedded in the recess of the hole 2.
