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 bending loads are applied, compressive force acts on the upper surface on the load side, and tensile force acts on the opposite side, resulting in The problem remains that compressive failure and cracks occur in 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 is made by sealing at least one surface of the lightweight aerated concrete layer 1 of the lightweight aerated concrete board with mortar coating 4, and then applying adhesive 3. A wooden veneer 2 is pasted through it. 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 from the indoor side. Taking this into consideration, the wooden veneer 2 is placed in contact with the side that will be the indoor side or the outdoor surface side after construction. Therefore, when the above-mentioned load is applied from the indoor side, the wooden veneer 2 stuck to the surface resists the above-mentioned load, so that the surface side of the aerated concrete board does not break due to compression or tension. However, when using it for partitions, etc., glue wood veneer on both the front and back sides. Furthermore, by bonding wooden veneers on both the front and back sides, there is no need to select between the front and back sides during construction, which has the advantage of saving construction time and improving strength.
以下本考案の実施例について説明する。 Examples of the present invention will be described below.
まず本考案軽量強化板の製造法について説明す

ンクリート板の表面は、非常にポーラスであるた
め、少なくとも片側表面をモルタル塗り４により
目止処理を行ない平滑面とする。 Next, the formwork into which lightweight cellular concrete has been poured is inserted into a curing or autoclave device, and after autoclave curing is performed, the mold is removed to obtain a lightweight cellular concrete plate. Since the surface of the lightweight cellular concrete board is very porous, at least one surface is sealed with mortar 4 to make it a smooth surface.
次に目止処理を行なつた軽量気泡コンクリート
板の表面にロールコーター、スプレツダーなどの
塗装装置を用いて適宜接着剤３を塗布する。 Next, the adhesive 3 is appropriately applied to the surface of the light-weight cellular concrete plate that has been subjected to the sealing treatment using a coating device such as a roll coater or a spreader.
接着剤３を塗布された軽量気泡コンクリート層
１の表面に木質単板２を載置した後、コールドプ
レス、ホツトプレス、ターンバツクルなど圧縮装
置を用いて圧縮接着する。 After a wooden veneer 2 is placed on the surface of a lightweight cellular concrete layer 1 coated with an adhesive 3, it is compressed and bonded using a compression device such as a cold press, a hot press, or a turnbuckle.
かくして第１図のように、表面側のみに木質単
板２を接着した本考案軽量強化板が得られる。 In this way, as shown in FIG. 1, the lightweight reinforced board of the present invention with the wooden veneer 2 bonded only to the front side is obtained.
なお本考案軽量強化板の中立層附近には従来技

必ずしも芯補強筋材を設けないという理由から板
材の強度が低下するとは考えられず、逆に製造工
程が簡易化され、低コストの軽量強化板を得るこ
とができるからである。 Note that unlike the aerated concrete board shown in the prior art, core reinforcing bars are not provided near the neutral layer of the lightweight reinforced board of the present invention. This is because when subjected to bending load, neither compression nor tension occurs in the central layer.
This is because the strength of the plate material is not necessarily reduced because the core reinforcing bars are not provided, but on the contrary, the manufacturing process is simplified and a lightweight reinforced plate can be obtained at low cost.
なお、この際第２図のようにまた軽量気泡コン
クリートの表裏両面にモルタル塗り４で目止処理
し、接着剤３を塗布した後その各々の面に単板を
圧縮接着してもよい。 At this time, as shown in FIG. 2, both the front and back surfaces of the lightweight cellular concrete may be sealed with mortar coating 4, and after applying adhesive 3, a veneer may be compressed and bonded to each surface.
木質単板は原木をスライサー、ロータリーレー
スなどによつて切削し得られる0.2〜５mm厚のも
のが好ましい。 The wood veneer preferably has a thickness of 0.2 to 5 mm and is obtained by cutting raw wood using a slicer, rotary lace, or the like.
建築用板は一般に大工施工が行なわれるため、
運搬、施工性を考慮しそのサイズは0.5〜４幅×
6′〜15′長が用いられておりその長さ方向と直角

長さ方向と直角方向の曲げ強度を向上させること
が望ましい。 Architectural boards are generally constructed by carpenters, so
Considering transportation and construction, the size is 0.5 to 4 widths
A length of 6' to 15' is used, and bending strength in a direction perpendicular to the length is required. Therefore, as shown in FIG. 3, it is desirable to bond the lightweight aerated concrete board so that the longitudinal direction and the fiber direction f of the wood veneer are parallel to each other in order to improve the bending strength in the direction perpendicular to the longitudinal direction.
また、木質単板表面に模様印刷、塗装、化粧シ
ート貼りなどを施こして、意匠性を向上すること

(a) Wood veneer 2 is compressed and bonded to the front or both sides of the wood veneer to improve its impact resistance, and when a bending load is applied, the tensile force acting on the opposite side of the load side is absorbed. Because it is held in place by the steel, compressive fractures and cracks do not occur, and the reinforcing effect against bending loads is improved.

強度に優れた軽量強化板が得られる。(d) The surface of the lightweight aerated concrete plate, which has a porous surface, is sealed with mortar coating 7 to create a smooth surface, compared to applying adhesive directly to the porous state where air bubbles are exposed on the surface.
A uniform adhesive layer can be obtained with a small amount of adhesive, the contact area between the lightweight cellular concrete and the adhesive is increased, and a lightweight reinforced board with excellent adhesive strength between the wood veneer and the lightweight cellular cement can be obtained.
