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.

In order to solve the above-mentioned problems of the conventional lightweight aerated concrete board, the present invention embeds a core reinforcing material 4 in or near the neutral layer of the lightweight aerated concrete layer 1 of the lightweight aerated concrete board, and at least coats the surface of one side with mortar. After sealing treatment is performed by coating 7, a wooden veneer 2 is attached via an adhesive 3. In other words, since the lightweight reinforced board of the present invention has such a structure, for example, when the board of the present invention is used as an interior or exterior material, the bending load and impact load applied to the board are mainly applied from the indoor side. In consideration of this, the wooden veneer 2 is glued to the indoor side or the outdoor surface side after construction. Therefore, when the above-mentioned load is applied from the indoor side, the mortar coating 7 on the surface of the core reinforcing material 4 and the wooden veneer 2 attached to the surface with an adhesive absorb the above-mentioned load in cooperation with the core reinforcing material 4. In order to counteract this, the surface side of the aerated concrete plate will not be damaged by compression or tension. However, when using it for partitions, etc., glue wood veneer on both the front and back sides. In addition, by gluing wood veneer on both the front and back sides, there is no need to select between the front and back sides during construction.
It has the advantage of saving construction time and improving strength.
