Disclosed is a refractory/heat insulating panel used in buildings and structures which must have a refractory performance. In the refractory/heat insulating panel (801), the mechanical strength and the fireproofing performance at the joint portions, which are weak portions in the panel, are increased by integrally forming inorganic boards (831) in the male and female joint portions (832, 836), filling a light-weight aggregate in the core material located at the male and female joint portions at a high density, or making the density of the core material at the joint portions higher than that at the center of the panel. Further, a nonwoven fabric is inserted between a core material (829) and a surfacing material (802) and between the core material (829) and a backing material (822), the surfaces of the surfacing material and the backing material facing the core material are embossed, a layer of isocyanurate foam and/or a layer of polyurethane foam are provided in the core material, or a wooden reinforcing material or a pipe-shaped member is buried in the core material to improve the adhesion between the core material and the surfacing material and between the core material and the backing material, the strength of the entire panel, refractory performance, etc. These structures also increase the strength and the refractory performance of the joint portions.

A mounting structure between a refractory/heat insulating panel and a substrate material, in which the refractory/heat insulating panel is formed by filling a core material between a surfacing material and a backing material, both having a square shape and being noncombustible, in which a male joint portion is provided at one of opposing sides, a female joint portion is provided at the other side, and mutual connection of panels is achieved by engagement between the male and female joint portions, and in which the substrate material is a C-shaped steel material which has a rear portion having vertical flat shape, side portions perpendicular to said rear portion, and a flap sections formed by inwardly bending a tip portions of the side portion, wherein the refractory/heat insulating panel is fixed to the substrate material by using a mounting bracket composed of a fixation portion and an engagement portion, the fixation portion being provided with a setting section corresponding to a side portion of the C-shaped steel material, a fixation section extending from one end of said setting section and corresponding to the rear portion of the C-shaped steel material, and an engagement section which is formed by being extended from the other end of the setting section to correspond to the flap section of the C-shaped steel material, and further bending a tip portion of the bent portion in a hook-like shape, said engagement section being engageable with said flap section; and the engagement portion extending from the setting section of the fixation portion in a direction opposite to the direction in which the fixation section and the engagement section extend, and having a shape corresponding to the shapes of the male and female joint portions of the refractory/heat insulating panel, and wherein refractory/heat insulating panels are joined by engaging the male joint portion and the female joint portion so that the engagement portion of the mounting bracket is interposed between the male joint portion and the female joint portion of refractory/heat insulating panels to be joined, an engagement groove portion of the mounting bracket is fitted on the flap section of the C-shaped steel material, and the fixation section is fixed to the rear portion of the C-shaped steel material with a fixture.
