[2] Embodiments of the present invention, including forms other than those described above, will be further described.

(1) The fiber mesh body of the present invention is intended to be embedded in a portion made of wet material.

The embedding position of the fiber mesh body of the present invention can be a position that is effective in preventing the occurrence of cracks due to thermal expansion and contraction of the portion formed of the wet material and deformation of the opening peripheral portion.

(1-2) The fiber mesh body of the present invention can be embedded parallel to the surface when the surface is formed of a wet material.

In the present invention, the surface formed by the wet material is generally a wall surface, but may be another free surface.

When embedding parallel to the surface formed by the wet material, the thickness of the wet material from the surface to the fiber mesh body is changed by the expansion and contraction due to heat of the part formed by the wet material and the deformation of the opening peripheral part. It is desirable to set it to an effective degree to prevent the occurrence of cracks etc. Such thickness may be, for example, 2 to 30 mm, preferably 5 to 20 mm, depending on the physical properties of the wet-laid material.

(1-3) The fiber mesh of the present invention is made of fiber filaments or mainly made of fiber filaments, and the fiber filaments are orthogonal to each other, It constitutes a mesh body.

The fiber mesh body may have, for example, one (or a plurality of) internal corners obtained by cutting out a part of a square, circle, other polygonal shape, or closed curved shape. The distance from the deep end position of the internal corner to the outer circumference of the fiber mesh body is constant or nearly constant, such as having an internal corner at one location by cutting out a quadrant of a circle. is preferable in terms of efficiency of reinforcement.

Fiber filaments include, for example, fibers, threads or fiber bundles.

As the fibers constituting the fiber-made filamentous body, those having necessary physical properties such as durability and strength can be used. As for the strength, for example, the tensile strength per 50 mm width in the vertical direction and the horizontal direction of the fiber mesh body may be 1200 N/50 mm or more. Specific examples of fibers include inorganic fibers such as glass fibers, carbon fibers and various mineral fibers; organic fibers such as acrylic fibers, vinylon fibers, nylon fibers, polyester fibers, polypropylene fibers and aramid fibers. Alkali-resistant fibers are suitable for wet materials exhibiting strong alkalinity such as mortar, and examples of suitable materials include alkali-resistant glass fibers (for example, those containing an amount of zirconia necessary for alkali resistance). can.

(1-6) The fibrous filaments in the entirety or at least in the portion including the internal corners form a mesh body by forming an orthogonal shape.

The filaments in any direction forming the orthogonal shape are inclined at 45 degrees with respect to any of the two sides forming the internal corner portion.

The 45-degree slanted shape can be 45-degree slanted, for example, 40-50 slanted, or 41-49 slanted. An angle of 42 to 48 degrees is preferred, 43 to 47 degrees is more preferred, and an angle of 44 to 46 degrees is even more preferred.
