があつた。 In boilers in which the furnace wall is constructed by arranging multiple stages of water tubes around the furnace, the furnace wall must often be supported in some way to provide reinforcement against the load caused by its own weight and the gas pressure within the furnace. Fig. 1 shows a method of supporting a furnace wall in a conventional once-through boiler, etc., in which furnace wall tubes 2 are gently raised around a furnace 1 to form a furnace wall. For support, a support fitting 3 is attached to the outside of the furnace wall, and is supported by a steel frame 5 via hanging bolts 4. FIG. 2 shows the details of the support by this support fitting, in which the support fitting 3 is applied to the furnace wall tubes 2 which are mutually connected by the strip plate 6 and constitute the furnace wall, and the support fitting 3 and the furnace wall tube The contact surfaces of 2 are fixed by welding 7. However, in this method, since the support fitting 3 and the furnace wall tube 2 are only in partial contact, there is a risk that the support strength will be insufficient.
Also, for the same reason, from the furnace wall tube 2 to the support fitting 3.
Heat transfer to the furnace wall tube 2 becomes insufficient.
A large temperature difference occurs between the support metal fitting 3 and the welding part 7, and thermal stress is concentrated on the welding part 7. Therefore, in addition to the lack of support strength mentioned above, the concentration of thermal stress has caused serious problems in terms of strength when supporting by conventional methods.
この発明の目的は上記した従来技術の問題点を
解決し、支持強度が高く、しかも溶接部に対する
熱応力の集中がない支持金具を提供することにあ
る。 An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a support metal fitting that has high support strength and does not cause concentration of thermal stress on the welded portion.
要するにこの発明は支持金具を二枚の側板と、
この側板の中央に配置した吊りボルト支持用の中

した溶接をしたものである。 In short, this invention uses a supporting metal fitting with two side plates,
It consists of a central plate for supporting hanging bolts placed in the center of this side plate, and the furnace wall engaging surface of the side plate is formed into a wave shape so as to come into close contact with the furnace wall, or this engaging surface is made into an independent block and substantially This is a continuous weld in the vertical direction.
以下この発明の実施例を添付図面を用いて説明

部として機能する。 In FIGS. 3 and 4, 3a is a side plate, and the furnace wall engaging end of this side plate 3a is connected to the furnace wall tubes 2 constituting the furnace wall and the strip plate 6 interposed between these furnace wall tubes. It is formed into a corrugated shape so that it can be tightly engaged. The corrugated shaped part is continuously welded vertically to the furnace wall tube 2 and the strip plate 6 by welding 7, and is connected and fixed over the entire surface. The center plate 8 is placed between the two side plates 3a fixed to the furnace wall in this way, and fixed by welding to the two side plates 3a, 3a. The center plate 8 functions as a connection part for hanging bolts (not shown) for supporting the furnace wall.

成形加工を施す必要がない。 In this embodiment, blocks that closely engage the furnace wall tube 2 and the strip plate 3 are used instead of forming a corrugated engagement portion on the side plate. In the figure, 3c indicates this block, and each block 3c tightly engages with each groove so as to fill the groove formed by the furnace wall tube 2 and the strip plate 6, and is fixed by welding. After the joint surface is made almost flat by the block 3c in this way, the rectangular side plate 3b is welded and fixed to this flat part and connected to the side plate, and the block is made such that the side connected to the furnace wall becomes a corrugated part. Similarly to the above case, the center plate 8 is welded and fixed between the two side plates 3b. In this embodiment, there is no need to perform any molding on the side plates.
この発明によればボイラ炉壁と支持金具を密着
して接続できるので支持強度を増加させることが
できる。 According to this invention, since the boiler furnace wall and the support fitting can be closely connected, the support strength can be increased.
また伝熱の主として行なわれる溶接線が実質的
に上下方向に連続し、強度増大のほか、炉壁から
支持金具に対する伝熱が良好であるため、溶接部
に熱応力が集中することがなく、このため経時的
な支持強度の低下等の問題が生じない。 In addition, the welding line, which is the main area of heat transfer, is substantially continuous in the vertical direction, which not only increases strength but also improves heat transfer from the furnace wall to the support fittings, so thermal stress does not concentrate in the welded area. Therefore, problems such as a decrease in support strength over time do not occur.
