The method for assembling the combustion device G will be described below. Here, an example is taken in which at least three or more side plates of the combustion device G include two first side plates 200 and two second side plates 300, and are configured to form a hollow upside-down truncated pyramid. List and explain.

First, a base portion 500 and four side frames are prepared. The four side frames are fixed to the base portion 500 in any of the above-described manners. After that, the bottom part 100 is prepared. Thereafter, the bottom portion 100 is supported by the support levers 620 of the four side frames in any of the above-described manners.

After that, two first side plates 200 are prepared. At least one first protrusion 220 of each first side plate 200 is inserted into a corresponding first support hole 110 of the bottom part 100. As a result, each first side plate 200 stands on the bottom part 100 while tilting away from each other.

After that, two second side plates 300 are prepared. Each second side plate 300 has at least one second convex portion 320 and one or other insertion portion 330, and if one or the other insertion portion 330 is provided with a slit 331, one second At least one second protrusion 320 of the side plate 300 is inserted into a corresponding second support hole 120 of the bottom part 100. At the same time, the slits 331 of one of the second side plates 300 and the insertion part 330 of the other side, and the slits 230 of the first side plates 200 of the other side are inserted into each other, and Insert the Z-direction side part of the slit 331 of one of the second side plates 300 and the other insertion part 330, and insert the Z-direction side part of the second side plate 300 into the slit 331 of the other insertion part 330. The Z′ direction side portion of one slit 230 of the first side plate 200 is inserted. As a result, the first end 311 of one second side plate 300 comes into contact with the first end 211 of one first side plate 200, so that one second side plate 300 and one first side plate 200 intersect, In addition, the second end 312 of one second side plate 300 abuts the first end 211 of the other first side plate 200, so that one second side plate 300 and the other first side plate 200 intersect.

In addition, the second end 312 of the other second side plate 300 abuts the second end 212 of the other first side plate 200, so that the other second side plate 300 and the other first side plate 200 intersect. In this way, the second side plates 300 are tilted apart from each other and stand up on the bottom portion 100, and the fire bed of the combustion device G is assembled.

When the slits 331 of one and the other insertion parts 330 of each second side plate 300 are omitted, one of the insertion parts 330 of one of the second side plates 300 is inserted into one of the slits 230 of one of the first side plates 200. One second side plate 300 and the other insertion portion 330 are inserted into one slit 230 of the other first side plate 200 from the Z direction side. As a result, the first end 311 of one second side plate 300 comes into contact with the first end 211 of one first side plate 200, and the second end 312 of one second side plate 300 contacts the other first side plate. 200 , and one second side plate 300 intersects with the other first side plate 200 . Thereafter, at least one second convex part 320 of the other second side plate 300 is inserted into the corresponding second support hole 120 of the bottom part 100, and one insertion part 330 of the other second side plate 300 is inserted into one of the second convex parts 320 of the other second side plate 300.

For example, an engaging convex portion is provided on either one of the Z′-direction end of at least one abutting portion 400 and the bottom portion 100, and an engaging hole is provided on the other, and the engaging convex portion At least one contact portion 400 may be directly fixed to the bottom portion 100 by fitting (FIT IN) into the engagement hole. Alternatively, the Z'-direction end of at least one abutment part 400 is bent into a substantially L shape, and the Z'-direction end of at least one abutment part 400 is attached to the bottom part 100 with bolts, nuts, etc. It may be directly fixed. Alternatively, at least one contact portion 400 may be indirectly fixed to the bottom portion 100. For example, the end of at least one abutment part 400 on the Z' direction side may be fixed to a fixture fixed to the bottom part 100. Note that the leg portions 600 and the base portion 500 can be omitted.
