Description

本発明は、打設コンクリートに埋まっているボイド管を剥離撤去しやすくするために、ボイド管を切りこんでいくボイド管切り込み具に関するものである。  The present invention relates to a void tube cutting tool for cutting a void tube so that the void tube embedded in cast concrete can be easily peeled and removed.

従来、ボイド管を撤去するときは、バール等をコンクリートとボイド管の間をにこじ入れて、力まかせに抜いていた。
なお、ボイド抜きを目的とした、フォーク状の棒で巻き取って引き抜く発明が知られている。
実用新案公開平６−３０３４５号公報 Conventionally, when removing the void tube, a bar or the like is squeezed between the concrete and the void tube and pulled out by force.
In addition, the invention of winding up with a fork-like rod and pulling it out for the purpose of void removal is known.
Japanese Utility Model Publication No. 6-30345

そのために、次のような問題点があった。
（イ）ボイド管はコンクリートに張り付いているために、ボイド管とコンクリートの間にバールをこじ入れても容易には剥がれず、力が必要であった。
（ロ）ボイド管開口部上に設備管などの障害物があると、ボイド管を抜くとき邪魔となって引き抜けなかった。
本発明は、以上の問題点を解決するためになされたものである。Therefore, there are the following problems.
(B) Since the void tube is attached to the concrete, even if a bar was inserted between the void tube and the concrete, it was not easily peeled off and a force was required.
(B) If there were obstacles such as equipment pipes on the opening of the void pipe, it could not be pulled out because it became an obstacle when the void pipe was pulled out.
The present invention has been made to solve the above problems.

課題を解決するための構造Structure to solve the problem

先端が尖った棒状の軸の前部に着脱可能なカッターの刃と、このカッターの刃を収める刃受け部を設け、後部にグリップを設ける。
打設コンクリートに埋まっているボイド管の上部にカッターの刃をあて、グリップ後部をハンマーで叩くことにより、ボイド管を切りこんでいくことを特徴とするボイド管切り込み具である。A detachable cutter blade and a blade receiving portion for receiving the cutter blade are provided at the front portion of a rod-shaped shaft having a sharp tip, and a grip is provided at the rear portion.
The void pipe cutting tool is characterized in that the void pipe is cut by placing a cutter blade on the upper part of the void pipe buried in the cast concrete and hitting the rear part of the grip with a hammer.

発明の効果Effect of the invention

本発明は、コンクリートに埋まっているボイド管が抜きやすくなるまで、ボイド管に何本もの切り込みを入れることができる。したがってボイド管の開口部上に障害物があっても、細断することで障害物をよけて抜くことができる。
また、ボイド管を細断することにより、力まかせに抜いていた苦労をなくし、スムーズに誰でも抜くことができる。The present invention can make a number of cuts in the void tube until it becomes easier to remove the void tube embedded in the concrete. Therefore, even if there is an obstacle on the opening of the void tube, the obstacle can be removed by being shredded.
In addition, by chopping the void tube, it is possible to remove the trouble that has been pulled out by force and to smoothly remove it.

以下、本発明の実施の形態を説明する。
（イ）先端（１）が尖っている棒状の軸（２）の後部に、グリップ（３）を設ける。
（ロ）軸（２）の先端（１）の後方にカッターの刃（４）を装着する刃受け部（５）を設ける。
（ハ）刃受け部（５）は基盤（９）肩部に固定軸（１０）を設け、固定軸（１０）は軸（２）に溶着又はネジ止めにより固定される。
（ニ）基盤（９）の内側にカッターの刃（４）を収容するための凹状の収納部（１１）を設ける。
（ホ）基盤（９）の片側にコの字状の開口部（６）を設ける。開口部（６）以外にカッターの刃（４）は収納部（１１）に収まることになる。
（ヘ）基盤（９）の上部にカッターの刃（４）を固定させるためネジ（７）を設ける。ネジ（７）を設けることでカッターの刃（４）は着脱可能となる。
（ト）収納部（１１）の開口部（６）へカッターの刃（４）が向くように収める。
本発明は以上の構成で、これを使用する時は、ボイド管淵（１２）にカッターの刃（４）をあてる。軸の先端（１）はボイド管とコンクリートの境（１３）にあてる。
ハンマー（１４）でグリップ（３）の後端（８）を叩いていく。カッターの刃（４）がボイド管（１５）を切っていき、先端（１）はボイド管とコンクリートの境（１３）へ挿入されていく。ボイド管（１５）が完全に切れるまで叩いていく。
ボイド管（１５）が抜けやすくなるまで、必要に応じて何本でも切り込んでいく。Embodiments of the present invention will be described below.
(A) A grip (3) is provided at the rear part of the rod-shaped shaft (2) having a sharp tip (1).
(B) A blade receiving part (5) for mounting the cutter blade (4) is provided behind the tip (1) of the shaft (2).
(C) The blade receiving portion (5) is provided with a fixed shaft (10) on the shoulder of the base (9), and the fixed shaft (10) is fixed to the shaft (2) by welding or screwing.
(D) A concave storage portion (11) for storing the cutter blade (4) is provided inside the base (9).
(E) A U-shaped opening (6) is provided on one side of the base (9). In addition to the opening (6), the cutter blade (4) is accommodated in the storage (11).
(F) A screw (7) is provided on the base (9) to fix the cutter blade (4). By providing the screw (7), the cutter blade (4) becomes detachable.
(G) The cutter blade (4) is stored in the opening (6) of the storage unit (11) so as to face.
The present invention is configured as described above. When this is used, the cutter blade (4) is applied to the void tube rod (12). The tip (1) of the shaft is applied to the boundary (13) between the void tube and the concrete.
The hammer (14) is used to strike the rear end (8) of the grip (3). The blade (4) of the cutter cuts the void tube (15), and the tip (1) is inserted into the boundary between the void tube and the concrete (13). Strike until the void tube (15) is completely cut.
Cut as many as necessary until the void tube (15) is easily removed.
