目農林土木建築用シートに関する。[Detailed Description of the Invention] The present invention provides a seawall sheet, a ground improvement sheet,
This invention relates to a coarse-grained sheet for agricultural, forestry, civil engineering, and construction, in which unit sheets with coarse grains, such as windbreak nets, curing sheets, sheets for various recreational facilities, and sheets for painting, are joined together adjacently to form a wide and vertically elongated structure.
従来目の粗いシート状物をつぎつぎと連結し
て、上記用途に供せしめる構造物を作成するに
は、塩化ビニル樹脂や塩化ビニリデン樹脂等の網
目状成型物や予め糸条全周に塩化ビニル樹脂等を
コーテイングした糸条を比較的粗大な網目を有す
る織物等に織成したものが使用されていた。 Conventionally, in order to create a structure that can be used for the above purpose by connecting coarse sheet materials one after another, it is necessary to use a mesh molded material such as vinyl chloride resin or vinylidene chloride resin, or to coat the entire circumference of the yarn with vinyl chloride resin in advance. The threads coated with the above were woven into a fabric with a relatively coarse mesh.
しかし、上記の塩化ビニル樹脂成型物等の場合
には、一枚物を相互に接合し幅広縦長の構造物に

合は殆んど不可能であるので、接合にはミシン縫
合又は接着剤による接合等他の手数が必要となり
従つてこの場合にあつても接合面の強力が十分で
なくまた作業が困難である等の欠点があつた。 However, in the case of the above-mentioned polyvinyl chloride resin molded products, when high-frequency stitching is used to join the single pieces together to create a wide and vertical structure, the constituent threads easily melt, resulting in brittle joints. In particular, when used as a structure, the overall strength was reduced to such an extent that it could be damaged by strong winds, making it impossible to achieve the desired purpose. In addition, in the case of vinylidene chloride,
Although it is a strong fiber itself, for the same reason as the above-mentioned PVC resin molding, high-frequency stitching is almost impossible, so other methods such as sewing machine stitching or adhesive bonding are required for joining. Therefore, even in this case, there were disadvantages such as insufficient strength of the joint surface and difficulty in working.
本発明は、上記の各欠点を除去して、高周波融

用シートを開発したものである。 The present invention eliminates the above-mentioned drawbacks, maintains sufficient strength as a structure without melting the core of the yarn at all even when high-frequency welding is performed, and has high joining strength due to high-frequency suturing. We have developed a new coarse-grained agricultural, forestry, and civil engineering construction sheet.

のである。 The high-frequency stitchable coarse agricultural, forestry, and civil engineering construction sheet of the present invention has a coarse fabric woven with threads that do not have high-frequency weldability as warp and weft, and a coarse fabric that covers the threads and has high-frequency weldability. In a coarse sheet that is similar to the polymer layer, the weft is curved in an arc shape, and the arc rate of this arc is defined by the following formula: Arc rate (%) = B / A × 100 [However, in the formula, A is It represents the width of the coarse sheet, and B
represents the length of a perpendicular line drawn from the apex of the arc to the straight line connecting both ends of the arcuate weft spanning the width] is within the range of 1 to 5%.

る。 The coarse sheet of the present invention is produced by high-frequency fusion stitching, so that there is no decrease in the strength of the threads constituting the sheet.
In addition, fusion stitching with other adjacent coarse sheets can be easily performed to form a long structure.

る。 Furthermore, in the case of the coarse sheet of the present invention, the degree of intersection and joining of the threads in the sewn portion of the coarse sheet is increased by curving the weft yarns in an arc shape to have an arcuate ratio of 1 to 5%, and It is the most effective method for high-frequency stitching of mesh sheets because it can create a so-called "curved point contact" state that provides torsional resistance to the tearing force acting on the joint surface.

れる。 The yarn without high-frequency fusing properties according to the present invention can be selected from, for example, natural fibers, synthetic organic fibers, or inorganic fibers. Filament yarns made of polyester or vinylon are preferred. However, other spun yarns, split yarns,
Tape-like threads or any other threads can also be used. These threads may be woven into any structure, but plain weave is the most common, and special fabrics such as leno weave and leno weave can also be used. The size of the mesh of the coarse sheet (i.e. the area of gaps between the threads) is preferably 15 mm x 15 mm, or 222 mm 2 or less when the mesh is square, especially 0.5 to 10 mm.

捺描画することも妨げない。 Next, the threads of the coarse sheet are coated with a polymer material that has high frequency weldability, and examples of this polymer material include polyvinyl chloride, urethane resin, ethylene. Vinyl acetate copolymers and others can be used. In particular, those mainly composed of polyvinyl chloride are preferred. The amount of polymer material coated is preferably at least 50% by weight, more preferably from 70 to 200% of the weight of the woven coarse fabric. Coating may be accomplished by dipping and drying the sheet in a solution of the polymeric material described above, although other known methods may be used as long as they do not conflict with the objectives of the present invention. Appropriate agents can be added to the polymer material to impart flame retardant properties, antifouling properties, and other properties. Further, it is not prohibited to print and draw designs etc. by a normal method.
本発明のさらに重要な特徴部分は、緯糸が弧状
に彎曲し、所定の弧状率を有している点に存す
る。 A further important feature of the invention is that the weft threads are curved in an arc and have a predetermined arc rate.
この弧状率は下式により算出される。 This arc rate is calculated by the following formula.
弧状率（％）＝Ｂ／Ａ×100
〔式中、Ａは粗目シートの幅を表わし、またＢは
該幅にまたがる弧状緯糸の両端を結ぶ直線に該弧
の頂点からおろした垂直の長さを表わす〕
いま、例えば幅Ａが2mのシートにおいて、弧
状緯糸の弧の頂点から該弧状緯糸の両端を結ぶ直
線におろした垂線の長さＢが２のとき、弧状率が
１％となる。 Arc ratio (%) = B / A × 100 [In the formula, A represents the width of the coarse sheet, and B is the perpendicular length taken from the apex of the arc to the straight line connecting both ends of the arc-shaped weft that spans the width. ] Now, for example, in a sheet with a width A of 2 m, when the length B of the perpendicular drawn from the apex of the arc of the arc-shaped weft to the straight line connecting both ends of the arc-shaped weft is 2, the arc ratio is 1%.
弧状率が５％より大きくなると、接合強度は大
となるが仕上り製品の外観に見劣が生じ、反対に
１％より小さい弧状率では接合強化効果が不十分
となる。 If the arcuate ratio is greater than 5%, the joint strength will be high, but the appearance of the finished product will be poor. On the other hand, if the arcuate ratio is less than 1%, the effect of reinforcing the joint will be insufficient.
緯糸を弧状に彎曲させるための最も好適な手段

シートに重合体を被覆する際、該重合体被覆粗目
シートを連続式熱処理機にかけ、シートの両端縁
を保持し、シートの中央部を該両端縁より遅れ
て、又は先行して進行させる方法である。 The most suitable means for curving the weft yarns into an arc is to immerse the woven sheet in a polymer solution to coat the sheet with the polymer, and then subject the polymer-coated coarse sheet to a continuous heat treatment machine. This is a method in which both edges of the sheet are held and the center portion of the sheet is advanced behind or ahead of the edges.

緯糸が他の粗目シートの経糸と交差するだけでな

ート２の夫々の緯糸の彎曲方向は反対であるが、
各緯糸が他の粗目シートの経糸と交差するだけで
なく、緯糸とも交差するので両シートの縫合部分
の接合強度が著しく高いものとなる。 In FIG. 1A, when the sewn ends of coarse sheet 1 and coarse sheet 2 are overlapped, each weft thread curved in an arc not only intersects with the warp thread of the other coarse sheet, but also intersects with one or more weft threads of the sheet. However, since high-frequency fusion bonding is performed at such a large number of intersections, the bonding strength of the sewn portions of both sheets is significantly increased. In addition, in FIG. 1B, the curvature directions of the wefts of coarse sheet 1 and coarse sheet 2 are opposite,
Since each weft intersects not only the warp of another coarse sheet but also the weft, the joint strength of the sewn portion of both sheets becomes extremely high.
本発明の粗目シートにあつては、その縫合予定
部分、例えば耳（側縁）部分の経糸の密度を、中
央部の密度より高くすることも、縫合部分の接合
強度を向上させる効果がある。 In the case of the coarse-grained sheet of the present invention, it is also effective to increase the density of the warp threads in the portion to be sewn, for example, the ear (side edge) portion, than the density in the central portion, to improve the joint strength of the sewn portion.

る。 The sheet of the present invention having coarse and arc-curved wefts not only has high strength itself, but also has high strength at the high-frequency seamed joint.
Even when the sheet structure is exposed to strong winds, it has a large torsional resistance and is extremely strong against tearing, making it extremely suitable for use in agricultural, forestry, and civil engineering construction structures.
