（産業上の利用分野）
この考案は、組立式プラチツク製グレーチング
に関する。[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a prefabricated plastic grating.
（従来の技術）
従来、床版は金属性の格子状のものが用いられ
ており、これらは工場の床や道路の側溝用の溝蓋
等に用いられているが、耐蝕性を要求される等そ
の用途から強化プラスチツクを素材としたものが
利用されている。(Prior Art) Conventionally, metal lattice-shaped slabs have been used for floor slabs, and these are used for factory floors and road gutter covers, etc. For this purpose, materials made of reinforced plastic are used.
そしてこの強化プラスチツク製グレーチングの
製造方法としては、注型法と引き抜き成形組み立
て法がある。 Methods for manufacturing this reinforced plastic grating include a casting method and a pultrusion assembly method.
しかし、前者は、一体成形のためクロスバーが
構造面からどうしても強度が増し、変形量が少な
く、破壊は小範囲で起こりグレーチングの分断が
ないという長所はあるが、金型面は滑面となる
が、大気側は気泡が発生したり、仕上げた場合に
は外観が劣り、コーナー部にヘアーラツクが発生
しやすく、完全硬化までに脱型出来ず生産サイク
ルが長く、また、内部に織り込むガラス含有率
（25〜30重量％）に限界がある等の短所も有する。 However, the former has the advantage that the crossbar is structurally stronger because it is integrally molded, the amount of deformation is small, the fracture occurs in a small area, and there is no separation of the grating, but the mold surface is smooth. However, air bubbles are generated on the atmospheric side, the finished appearance is poor, hair sagging tends to occur at the corners, the mold cannot be removed until it is completely cured, resulting in a long production cycle, and the glass content to be woven into the interior is poor. It also has disadvantages such as a limited amount (25 to 30% by weight).
これに対して後者は、一般的にはベアリングバ
ーに穴明けし、クロスバーを貫通後接点はエポキ
シ樹脂等で接着する２ピース方式であり、ガラス
含有率が70重量％まで可能で部材の強度は非常に
高く、部材成形は連続成形が可能で生産サイクル
が短く、全面が滑面であり美観に優れ、メインバ
ー、クロスバーのピツチが自由に変更できるとい
う長所と、組み立て部材は材料加工が必要とな
り、加工精度が要求され、破壊はグレーチングの
分断もあり、接点を樹脂接着するため変形が大き
くなれば溶接が剥がれ強度が著しく劣化するとい
う欠点もある。 On the other hand, the latter is generally a two-piece method in which a hole is drilled in the bearing bar, the contact point is bonded with epoxy resin after passing through the cross bar, and the glass content can be up to 70% by weight, which increases the strength of the member. The advantages are that the parts can be molded continuously, the production cycle is short, the entire surface is smooth and the appearance is excellent, the pitch of the main bar and cross bar can be changed freely, and the assembly parts can be easily processed. The problem is that the grating can be broken, and the contact points are bonded with resin, so if the deformation becomes large, the weld will peel off and the strength will deteriorate significantly.
（考案が解決しようとする問題点）
そこでこの考案は、引き抜き組み立て法による
強化プラスチツク製グレーチングであつて、上記
の各欠点を除去するために考案されたものであ
り、外観がよく、組み立て後の接点の接着も補助
的に行う３ピース方式の組立式強化プラスチツク
製グレーチングを提供するものである。(Problems to be solved by the invention) Therefore, this invention is a reinforced plastic grating made by the pull-out assembly method, and was devised to eliminate each of the above-mentioned drawbacks. The present invention provides a three-piece prefabricated reinforced plastic grating that also provides auxiliary bonding of contacts.
