Description

発明の詳細な説明Detailed Description of the Invention

この発明は、鉄筋コンクリートの床に組まれた鉄筋を持ち上げ、コンクリートの被りを得るスペイサーを差し入れするための道具に関するものである。  The present invention relates to a tool for lifting a reinforcing bar assembled on a reinforced concrete floor and inserting a spacer for obtaining a concrete covering.

従来床に組まれた鉄筋は、バール等で持ち上げスペイサーを差し入れていた。  Conventionally, reinforcing bars built on the floor were lifted with a bar or the like and a spacer was inserted.

発明が解決しようとする課題Problems to be solved by the invention

これは次のような欠点があった。
イ．床に組まれた鉄筋と作業する人の重量を合わせた鉄筋をバールの先端より少し手前にコンクリートの製のサイコロ等を挾み、てこの要領で鉄筋を持ち上げのための、作業する人の腰に大きな負担がかかっていた。
ロ．床に組まれた二層の鉄筋の上層鉄筋に、うま型スペイサー等を差し入れは、長いバールの先端より少し手前に１０ｃｍぐらいの角材等を挾み、てこの要領で鉄筋を持ち上げ作業する人はその組まれた鉄筋が足場となり、作業に危険が伴い作業効率が悪かった。
ハ．上記の作業工法のため、所定の位置にスペイサーを入れるのが軽減されていたと思う。
本発明は、以上の欠点を解決するためになされたものである。This has the following drawbacks.
A. Reinforce the worker's waist to lift the rebar in the manner of a lever by holding a concrete dice etc. slightly before the tip of the bar. Was a heavy burden.
B. If you insert a space spacer, etc., into the upper layer of the two layers of reinforcing bars on the floor, the person who lifts the reinforcing bars in the manner of a lever, rubs about 10cm squares, etc. slightly before the end of the long bar. The assembled rebars were used as scaffolding, and the work was dangerous and the work efficiency was poor.
C. Because of the above work method, I think it was reduced to put a spacer at a predetermined position.
The present invention has been made to solve the above drawbacks.

課題を解決するための手段Means for solving the problem

段違いに曲げたシャフト（２）の頭部に吊り金具（５）と支柱（４）を設ける、そしてシャフト（２）の上部にグリップ（１）を設ける。
本発明は、以上の構成よりなる床に組まれた鉄筋のコンクリートの被りを得るスペイサーを差し入れするための道具である。A hanging bracket (5) and a support (4) are provided on the head of the shaft (2) bent in a stepwise manner, and a grip (1) is provided on the top of the shaft (2).
The present invention is a tool for inserting a spacer for obtaining a concrete covering of a reinforcing bar assembled on a floor having the above-described configuration.

以下、本発明の実施の形態を説明する。
（イ）金属を主材とし、図１・図２で示す細長い円形管のシャフト（２）を曲げ、頭部に吊り金具（５）と支柱（４）を設け、その上部にゴムのグリップ（１）を差し入れたものである。
（ロ）吊り金具（５）は、図１・図３で示す平鋼の上部に数ケ所のピンの通し穴（５１）を設け、その下部を９０度の捻り（５３）を加え、その下部を４５度外側へ曲げた平鋼外面の位置で垂直に曲げ、さらに水平に９０度曲げ平坦（５４）とした頭部に外れ止め（５５）を設ける。
（ハ）支柱（４）は、図１・図３で示す平鋼の上部に数ケ所のピンの通し穴（４１）を設け、その下部の両端にテーパー（４４）をつけ、ボルト（７）の上部に設けた、みそ（７１）に差し込み溶接（１２）で固定する．次にボルト（７）のかぶよりナット（８）と、お椀形の支持台（９）と発条（１０）を差し込みナット（１１）で固定し、その発条（１０）はナット（８）で締めつけボルト（７）に設けた穴（７２）にＲ型ピン（７３）を差し込みナット（８）のゆるみを防ぐ、さらにナット（１１）のゆるみは図３で示すボルト（７）の頭部にかしめ（７４）を加えナット（１１）のゆるみを防ぐ。
（ニ）シャフト（２）は、図３で示す丸棒鋼の補強材（３）をシャフト（２）の途中に挿入することにより簡単な曲げ機でシャフト（２）の円形の変形が生じなく曲げられ、そのシャフト（２）の補強も得られその曲げ寸法は支柱（４）芯より８０ｍｍで内曲げ角度が９０度、さらに上部に１２０ｍｍで内曲げ角度が１３０度とする。さらにシャフト（２）頭部の吊り金具（５）と支柱（４）は芯々で約８０ｍｍ間隔でそれぞれ縦長の開口とし、その開口の端部と吊り金具（５）・支柱（４）の外面との隙間を約５ｍｍ設ける。さらにシャフト（２）に支柱（４）と吊り金具（５）をピン固定とする横の穴（２４）を設ける。
次に、シャフト（２）の頭部は丸板鋼のキャップ（２３）を溶接（１２）で固定し、その頭部の補強する、さらにシャフトの上部は通気口（１１）を設けた、ゴムのグリップ（１）を両面テープを併用し差し込み固定する。
（ホ）図２で示す吊り金具（５）と支柱（４）は配筋された鉄筋の上げ高さに合わせリベット型ピン（６）と２枚の座金（６２）を用いシャフト（２）と固定し、そのリベット型ピン（６）の穴（６１）にＲ型ピン（６３）を差し込みピンの外れを防ぐ。
本発明は、以上の構成よりなっている。
本発明を使用するときは、建築基準法に定められた鉄筋とコンクリートの被り厚さを得るため、床に配筋された鉄筋を持ち上げ所定のスペイサーを入れる場合、下記で実施例を説明する。
（ヘ）スペイサーの高さが５０ｍｍの場合、図４・図５で示す一層の床配筋はシャフト（２）頭部に設けた吊り金具（５）のピン差し込み穴は、穴（５１）で支柱（４）のピン差し込み穴は、穴（５２）に合わせ配筋された下端筋（１３）に外れ止め（５５）を設けた吊り金具（５）の頭部を差し入れ、シャフト（２）のグリップ（１）を片手で押し下げ下端筋（１３）の下に所定のスペイサーブロック（１５）を挿入し、この作業を所定の間隔にスペイサーを次から次へと挿入し作業が完了となる。
（ト）スペイサーの高さが１５０ｍｍの場合、図６・図７で示す二層の床配筋は、上記（ホ）の方法で一度に二層の鉄筋を上げ、その下層の下端筋（１３）にスペイサーブロック（１５）を入れる。
次に、吊り金具（５）の穴の位置を穴（５２）と支柱（４）の穴の位置を穴（４３）に変え、外れ止め（５５）を設けた吊り金具（５）の頭部を上層の下端筋（１３）に差し入れ、シャフト（２）のグリップ（１）を片手で押し下げ上層下端筋（１３）の下に所定の、うま型スペイサー（１６）等を挿入しこの作業を所定の感覚にスペイサーを次から次へと挿入し作業が完了となる。
（チ）上層下端端の高さが１５０ｍｍ以上の場合、吊り金具（５）と支柱（４）に設けたピンの差し込み穴の位置を高く変えることにより対応できる。
（リ）床に組まれた配筋は垂直の移動はできるが水平の移動はできないため下記の各支点の組み合が対応している。
（ア）吊り金具（５）の下部を平坦としたことにより下端筋（１３）とに滑りが生じる、さらにシャフト（２）に設けた挿入口（２２）が前後に約５ｍｍの隙間を設け、さらにリベット型ピン（６）で結合したことにより対応している。
（イ）シャフト（２）に設けた支柱（４）の挿入口（２１）と支柱（４）が前後に約５ｍｍの隙間を設け、それぞれをピンで結合し、さらにお椀型の支持台（９）の中に発条（１０）を設けたことにより、その支柱（４）が下端筋（１３）を持ち上げるとき前後に動くことによ対応している。
