JP3995095B2 - Supporting bracket for inorganic fiber block and method of construction on furnace wall - Google Patents

Description

  The present invention relates to a support fitting for an inorganic fiber block and a method for installing the same on a furnace wall, for example, a support fitting for fixing an inorganic fiber block used for a lining of an industrial furnace to a furnace wall, and an inorganic fiber block using the support fitting. It relates to the construction method on the furnace wall.

  Conventionally, as an installation method for the furnace wall of an industrial furnace, an inorganic fiber block is skewed at the point of an L-shaped and T-shaped support fitting called L pin and T pin, respectively, and the support fitting is used as a furnace wall. A method of fixing by welding is generally employed.

  When the L pin and the T pin are welded and fixed to the furnace wall, the apex for inserting the inorganic fiber block and the furnace wall surface must be parallel. If this is not parallel, a gap will be generated between the inorganic fiber block fixed with the L pin and the T pin and the furnace wall surface, and the inorganic fiber block cannot be accurately fixed to the furnace wall. However, welding and fixing the L pin and the T pin in parallel to the furnace wall as described above requires considerable skill and requires a great deal of time for construction.

In order to solve the problems of the L pin and the T pin, Patent Document 1 discloses a seat plate member fixed to the furnace wall, a long projection from the seat plate member, and a support for inserting and supporting an inorganic fiber block. A support metal fitting comprising a rod member and a groove-shaped engagement portion that can be held so as not to shift the holding position when the tip end portion of the rod member is held is shown. .
