関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is used as a waste form for pouring concrete to produce concrete slabs and concrete walls. , relates to a reinforcing structure for an inorganic plate made of calcium silicate or the like.

開昭６２−１７８６４４号公報参照）。Today, various inorganic and organic long fibers such as glass fiber, carbon fiber, metal fiber, aramid fiber, and silicon carbide fiber are used as reinforcement structures for inorganic boards such as cement mortar boards, concrete boards, and calcium silicate boards. It is known that the inorganic plate is reinforced in terms of bending strength by arranging the inorganic plate within the inorganic plate. As an example of this, it is known that long fibers are arranged in positions close to the front and back surfaces of a concrete board in a manner that follows the surface of the board (for example, see Japanese Patent Application Laid-open No. 178644/1983). .

に立っていない。However, when using the above-mentioned conventional reinforcement structure, there is a large difference in the loads acting on the front and back surfaces of the plates, such as waste forms for concrete pouring and simple sheet piles for earth retention, and the bending stress is only applied to one side. When considering an inorganic board used under conditions where bending stress acts as a tensile force, the long fibers located near the board surface on the side where bending stress acts as a tensile force will resist the tensile force and cause the bending of the board surface. For example, to prevent cracks caused by
Although they act effectively against bending stress, the long fibers located near the other plate surface are not useful as a countermeasure against bending stress.

それら板表面に沿った姿勢で配設するといった手数のか
かる長繊維設置作業が２回も必要となって作業面からも
コストアップを招来するのである。Therefore, as mentioned above, in an inorganic plate where bending stress only acts on one side, it is difficult to arrange long fibers near the front and back surfaces of the plate, which is too long for the required bending resistance. The amount of fiber used is unreasonably large, leading to an increase in material costs.Furthermore, the long fiber installation process is labor-intensive, as the long fibers are placed close to the front and back surfaces of both boards in a posture along the board surfaces. It is necessary to do this twice, which leads to an increase in costs from a work standpoint.
そして、一方側への曲げ応力のみが作用する条件下で使
用する無ｍ質板の用途は多岐にわたり、かつ、多々発見
されており、その結果、今日においては、そのような用
途に使用できる耐曲げ性能をそなえながらも、安価であ
る無機質板が強く望まれている。A wide variety of applications have been discovered for amorphous plates used under conditions where only bending stress is applied to one side. There is a strong desire for an inexpensive inorganic plate that has good bending performance.
本発明の目的は、無機質板に対する前述の強い要望を十
分に充足できるようにする点にある。An object of the present invention is to fully satisfy the above-mentioned strong demand for inorganic plates.
本発明による無機質板の補強構造の特徴構成は、無機質
板内のうち表裏一方の板表面に近い箇所にのみ、補強用
の長繊維を板表面に沿った姿勢で配設してある点にあり
、その作用・効果は次の通りである。The characteristic structure of the reinforcement structure for an inorganic board according to the present invention is that reinforcing long fibers are arranged in a posture along the board surface only in locations close to the board surface on one of the front and back sides of the inorganic board. , its actions and effects are as follows.
無機質板の表裏の画板表面のうち長繊維に近い側の板表
面を引張力作用側とする曲げ応力が無機質板に作用した
とき、長繊維によって、無機質板に作用する曲げ応力に
起因して生じる引張力に抗して板表面のひび割れを防止
できるため、長繊維に近い側の板表面を引張力作用側と
する曲げ応力に対する耐曲げ性能を十分に確保できる。When a bending stress is applied to the inorganic board, with the tensile force acting on the surface of the drawing board on the front and back sides of the inorganic board, which is closer to the long fibers, the bending stress that acts on the inorganic board due to the long fibers is generated. Since cracks on the plate surface can be prevented against tensile force, sufficient bending resistance against bending stress with the plate surface closer to the long fibers acting as the tensile force side can be ensured.
しかも、一方の板表面近くにのみ耐曲げ性能向上のため
の長繊維を配設してあるため、前述した従来のものに比
較して、長繊維の使用量を半減できるとともに、長繊維
の配設といった手数のかかる作業の数を半減できる。Furthermore, since long fibers are arranged only near the surface of one plate to improve bending resistance, the amount of long fibers used can be halved compared to the conventional type mentioned above, and the long fibers are The number of labor-intensive tasks such as installation can be halved.
その結果、一方側への曲げ応力のみが作用する条件下で
の多岐にわたる用途に使用できながらも、安価に作製で
きる無機質板を提供できるようになった。As a result, it has become possible to provide an inorganic plate that can be manufactured at low cost and can be used in a wide variety of applications under conditions where only bending stress is applied to one side.
特に、無機質板のうち、長繊維とそれに近い側の板表面

のの、長繊維による破壊防止作用が板表面にまで及ばず
、板表面にひび割れが生じ易いといったことが実験を繰
返した結果、知見したからである。In particular, it is desirable to set the thickness of the surface layer portion of the inorganic board between the long fibers and the surface of the board near the long fibers to be 0.5 to 5 mm. This is because if it is made thinner than this, the binding force between the inorganic board and the long fibers becomes weaker, and the tensile strength effect of the long fibers cannot be expected.On the other hand, if the structure of reinforced concrete or steel-framed concrete is adopted as is and it is made thicker than that, Experiments have shown that when a tensile force is applied, the inorganic plate near the long fibers can be prevented from being destroyed by the tensile force, but the long fibers do not have the effect of preventing damage to the plate surface, and cracks are likely to occur on the plate surface. This is because I discovered this after repeating the process.
また、無機質板はコンクリート打設用の捨型枠として非
常に有用である。なぜなら、長繊維が配設されていない
側の板表面は、曲げ応力が作用したとき圧縮力を受けて
破損するおそれがあるが、その破損のおそれがある板表
面は打設コンクリートと結合して修復され、強度面およ
び外観とに悪影響が全くないからである。In addition, inorganic boards are very useful as waste forms for concrete pouring. This is because the plate surface on the side where long fibers are not arranged may be damaged by compressive force when bending stress is applied, but the plate surface where there is a risk of damage is bonded to the poured concrete. This is because it has been repaired and there is no adverse effect on strength or appearance.

It is used as a waste formwork (A) with the plate placed on the outside, and although tensile force is applied to the surface of the outer plate due to bending stress caused by pouring the concrete (B) that will become the slab or wall, this By countering the tensile force with the long fibers (2), cracks on the board surface are prevented.
