【考案の詳細な説明】 (産業上の利用分野) 本考案はコンクリートの型取用定規に関し、詳細には軽
量で反りが少なく、かつ安価なコンクリートの型取用定
規に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a concrete molding ruler, and more particularly to a lightweight concrete molding ruler with little warpage and at low cost.
(従来の技術) 従来より主に土木建築工事において、コンクリートの型
取りに使用する定規については、一般的に原木を切削し
た木材単板をそのまま使用することが多かった。(Prior Art) Conventionally, a wood veneer obtained by cutting a raw wood is generally used as it is for a ruler used for molding concrete mainly in civil engineering and construction work.
ところが前記木材単板より成る定規は、 比較的重い原木を切削したままのものを使用するため
重くて作業しずらい。However, the ruler consisting of the above-mentioned wood veneer is heavy and difficult to work because it is used by cutting a relatively heavy log.
木材単板の木目による反りが発生する。Warpage occurs due to the grain of wood veneer.
原木資源の欠乏による原料不足等も原因して高価であ
る。It is expensive due to lack of raw materials due to lack of raw wood resources.
という欠点があった。There was a drawback.
そこで、上記〜の欠点に鑑み、プラスチックから成
る定規が提案された。Therefore, in view of the above-mentioned disadvantages, a ruler made of plastic has been proposed.
(考案が解決しようとする課題) しかしながら、上記プラスチックから成る従来の定規
は、木材単板より成るものと比べると反りが解消される
ものの木材に比べて熱変化に対する寸法安定性に劣
る。吸水性がないという欠点があった。(Problems to be solved by the invention) However, although the conventional ruler made of the above plastic can eliminate the warp as compared with the one made of a wood veneer, it is inferior in dimensional stability against heat change as compared with wood. It had the drawback of not absorbing water.
ここで何故コンクリートの型取用定規に吸水性が必要か
というと主に以下(イ)及び(ロ)の理由による。Here, the reason why the water absorption is required for the concrete ruler is mainly due to the following reasons (a) and (b).
つまり、 (イ)吸水性がないと固化する前のセメント混練物の水分
の表面張力によって、コンクリートの角が盛り上がった
りしてきれいな型取りができ難い。In other words, (a) If there is no water absorption, the surface tension of the water of the cement kneaded product before solidification causes the corners of the concrete to rise, making it difficult to take a clean mold.
(ロ)固化する前のセメント混練物中の水分が吸収されな
いと定規との接触面においてセメントの固化の妨げと成
る。(B) If water in the cement kneaded product before solidification is not absorbed, it will hinder the solidification of cement at the contact surface with the ruler.
そこで案出したのが本考案であり、その目的とするとこ
