る。[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a stone panel used for constructing the interior and exterior walls and floors of buildings, and more specifically, the surface material is made of stone made of natural stone or artificial stone. This relates to stone panels made of stone.

難であるという問題がある。[Conventional technology] Taking advantage of the beauty and durability of stone, natural stones such as marble and granite or artificial stones are used for the interior and exterior walls and floors of buildings.
17. The thickness of stone is about 20 to 50+ meters depending on the strength of the stone and processing precision, and it is difficult to handle because it is heavy and has the risk of chipping and cracking. There is a problem.
また最近、石材を薄＜（１，０〜５．（１＋ｍ）切断す
る技術が開発されて大きな話題になっている。Recently, a technique for cutting stone to a thickness of <(1.0 to 5.(1+m)) has been developed and has become a hot topic of discussion.
しかしながら石材のみでは強度的に弱く、取り扱い時、

昭６３−２２２８５０号公報に開示されるものがある。However, stone alone is weak in strength, and when handled,
Cracks and chips occurred during transportation, making it difficult to use as a building material. In order to improve this drawback, the back side is made of foam material and FRP.
, metal plates, honeycomb cores, etc. are used as backing materials. An example of a stone material backed with an FRP layer is disclosed in Japanese Patent Application Laid-Open No. 63-222850.

トランドマットを使用すると、コストが安くなると共に
曲げやすくなるが、強度が低下するという問題がある。[Problem to be solved by the invention] By the way, in a stone material backed with an FR, P layer, if cloth is used as the reinforcing fiber layer of the FRP layer, the strength (tensile strength) will increase, but the strength (tensile strength) will increase. , it becomes difficult to bend. Furthermore, there is a problem that the cost is currently high and anisotropy occurs. If a chip dust strand mat is used for the reinforcing fiber layer and L, the cost will be reduced and it will be easier to bend, but there is a problem that the strength will decrease.

ねじれの原因となる。In other words, when attaching FRP to stone, the problems are the strength against bending, the ability to follow bending, and the warpage of the panel. Cross is superior in terms of strength, and mat is better against warping because it follows the curves of the stone and bends easily. In addition, the cross remains anisotropic, which causes the stone to twist.

The reinforcing fiber layer 3 of the FRP layer 2 is composed of a layer of chipped strand pine (pine) 3a and a layer of cloth 3b. It is preferable that the ratio of the weight per unit area (g/m2) of the tipped strand pine) 3a to the weight per unit area (g/m2) of the cloth 3b is 0.5 to 2.0. FRP/!

A method of applying resin to the stone surface by layering mat and cloth. ■A method of curing prepreg by layering it on a stone surface. ■Method of pasting an FRP sheet formed in advance in a separate process onto a stone surface. Among the above methods, method (2) ensures that the shrinkage during curing does not leave any residue and there is little warpage when the panel is made. Possible resins for the FRP layer 2 include polyester, epoxy, acrylic, etc., but polyester is often used. The reinforcing fiber layer 3 may be made of plus fiber, polypropylene fiber, carbon II fiber, etc., but glass fiber is often used.
