1. A heat insulating wall comprising:
a heat insulating block comprising an inorganic fiber aggregate mat that is folded up and that has at least two folds on a face thereof which is to be fixed to a furnace shell; and
a fixture having at least two beams, wherein
the beams of the fixture are inserted into the folds of the heat insulating block, and the fixture is fixed to the furnace shell, and thereby, the heat insulating block is installed on a furnace wall, and
support points of the beams at which the beams support the heat insulating block are outside the heat insulating block,
wherein the fixture comprises plural beams that are installed in two different heat insulating blocks, one of which being the heat insulating block, and the beams including a first beam area installed in one of the heat insulating blocks and a second beam area installed in another one of the heat insulating blocks,
wherein the first beam area and the second beam area are each extended in a direction away from each other starting from the fixture, and
wherein the heat insulating block is installed on the furnace shell by two fixtures, one of which being the fixture.
