る問題点を残している。 This fireproof covering board has metal lath buried in a layer in the center of the internal board thickness, and has improved impact resistance due to the use of wire mesh.
Since the wire mesh is formed in the center layer relative to the thickness of the plate, its reinforcing effect against bending loads is small, and when a bending load is applied, compressive force acts on the upper surface on the load side, and tensile force acts on the opposite side. There remains the problem of compression failure and cracking of the aerated concrete section due to tensile force.

強度の保持を図つたものである。 However, as shown in FIG. 3, the high-density cellular concrete layers 3a and 3b of the lightweight reinforced board of the present invention may be provided only on the surface when used as an interior or exterior material. Generally, when used for interior and exterior materials, the high-density aerated concrete layer 3 is applied only from the surface side, as it is subject to large bending loads and impact loads due to impacts, changes in temperature, etc.
By providing this, the strength can be efficiently improved. Furthermore, since high-density aerated concrete was used for the front and back layers, strength was maintained within a range that did not inhibit the air permeability of the low-density aerated concrete to the core layer.
