Description
本発明は、漏水を伴うひび割れや経時変化によるコンクリート躯体のひび割れに対し注入材を充填補修するコンクリート躯体補修方法及びそれに使用されるコンクリート躯体補修用挿入型注入プラグに関するものである。 The present invention relates to a concrete case repairing method for filling and repairing an injecting material for cracks caused by water leakage and cracks in a concrete case due to changes over time, and an insertion-type injection plug for repairing a concrete case used therefor.
従来、数多くある多種多様の注入プラグは以下のものがあった。低圧注入では、コンクリート構造物の渇いている面に接着剤による張付型プラグがあった。高圧注入では、基本的に挿入するパイプの中間にゴム管を取り付け、ゴム管に対し縦方向の圧力を加え、縮めることによりゴム管を膨張させ、削孔穴と注入プラグとの空隙を塞いでいた。 Conventionally, there are many various types of injection plugs as follows. With low pressure injection, there was a glued plug on the dry surface of the concrete structure. In high-pressure injection, a rubber tube is basically installed in the middle of the pipe to be inserted, pressure is applied to the rubber tube in the vertical direction, and the rubber tube is expanded by contraction to close the gap between the hole and the injection plug. .
しかしながら、従来の注入プラグを削孔穴に固定するには、接着剤による接着型や挿入型では、注入パイプの中間に取り付けたゴム管にネジ式の圧力を加え、ゴム管を膨張させて空隙を塞ぐもので、コンクリート躯体状況の把握と経験が必要となり、更に一箇所の固定に数分の時間を要していた。 However, in order to fix the conventional injection plug to the hole, in the adhesive type or insertion type using an adhesive, a screw type pressure is applied to the rubber tube attached in the middle of the injection pipe to expand the rubber tube to create a gap. It was necessary to grasp and experience the condition of the concrete frame, and it took several minutes to fix one place.
また、注入材の注入が確実に実施されているかどうかの確認が出来なかった。 Moreover, it was not possible to confirm whether or not the injection material was reliably injected.
そこでこの発明は、短時間で、熟練を必要とせず、充填を確実に判断して施工できるコンクリート躯体補修方法を提供することを第一の目的としている。
また、この発明はコンクリート躯体の補修方法に使用されるコンクリート躯体補修用挿入型注入プラグを提供することを第二の目的としている。
SUMMARY OF THE INVENTION Accordingly, a first object of the present invention is to provide a concrete frame repairing method that can be applied in a short period of time without requiring skill and by reliably determining filling.
A second object of the present invention is to provide an insertion-type injection plug for repairing a concrete frame used in a method for repairing a concrete frame.
第一の目的を達成するコンクリート躯体補修方法は、躯体補修用挿入型注入プラグから注入材を注入するコンクリート躯体補修方法であって、
ケイ酸アルカリ水溶液により溶けるガラス質を混入したプラスチックからなっている躯体補修用挿入型注入プラグの注入プラグ本体が先端に向かって先細りとなった先端部をケイ酸アルカリ水溶液に浸して潤滑性を付与し、
潤滑性が付与された先端部の外周にアメゴムチューブを挿入して被せ、ケイ酸アルカリ水溶液をガラス質と反応させて潤滑性を無くし、アメゴムチューブを先端部に接着固定し、
アメゴムチューブが固定された躯体補修用挿入型注入プラグを削孔穴に差し込み、
躯体補修用挿入型注入プラグを介して注入材をコンクリート躯体に注入することを特徴としている。
The concrete body repair method for achieving the first object is a concrete body repair method in which an injection material is injected from an insertion-type injection plug for body repair,
Lubricating by inserting the tip of the injection plug body of the insertion type injection plug for repairing the housing, which is made of plastic mixed with glass that is melted by the alkali silicate aqueous solution, into the aqueous solution of alkali silicate. And
Insert the candy rubber tube on the outer periphery of the tip part to which lubricity is imparted and cover it, react the alkali silicate aqueous solution with vitreous to eliminate the lubricity, and fix the candy rubber tube to the tip part,
Insert the insertion plug for repairing the housing with the candy rubber tube fixed into the hole,
It is characterized by injecting the injected material into the concrete frame through the insertion plug for repairing the frame.
また、第二の目的を達成するコンクリート躯体の補修用挿入型注入プラグは、
請求項1のコンクリート躯体補修方法に使用されるコンクリート躯体補修用挿入型注入プラグにおいて、
注入プラグ本体は、先端に向かって先細りとなった先端部を有し、ケイ酸アルカリ水溶液により溶けるガラス質を混入した半透明のプラスチックからなっており、先端部の外周にアメゴムチューブが挿入されていることを特徴としている。
In addition, the insertion plug for repairing the concrete frame to achieve the second purpose is
In the insertion plug for concrete frame repair used in the concrete frame repair method of claim 1,
The injection plug body is made of a translucent plastic mixed with glass that is melted by an aqueous alkali silicate solution, and has a tip that tapers toward the tip. It is characterized by being.
本発明によれば、テーパー型プラグにガラス質を混入し成形したことにより、アメゴムチューブとテーパー型プラグをケイ酸アルカリ水溶液に浸してから挿入することにより、先に潤滑剤として機能し、後に接着剤として機能する。そのため、経験がなくとも一穴のプラグ固着を数秒での取り付けが可能となった。また、従来のプラグでは、注入が確実に実施されているかの管理が難しいとされていたが、本発明では注入プラグが半透明であり、注入材が充填されていることが目視によって確認することができる。
また、プラグをテーパー型にしたことで、経験が無くとも容易に取り付けることができる。
According to the present invention, the glass plug is mixed with the taper type plug and molded, so that the candy rubber tube and the taper type plug are immersed in an alkali silicate aqueous solution and then inserted into the taper type plug. It functions as an agent. For this reason, it was possible to attach a single hole plug in a few seconds without experience. In addition, in the conventional plug, it was considered difficult to control whether the injection was reliably performed, but in the present invention, it is visually confirmed that the injection plug is translucent and filled with the injection material. Can do.
Further, since the plug is tapered, it can be easily attached without experience.
コンクリート躯体が濡れている場合や経年劣化の進行が進み粗密なコンクリートでも対応できる。 It can be used even when the concrete frame is wet, or even with dense concrete due to the progress of deterioration over time.
震災による防火水槽の注入止水では，コンクリート躯体の経年劣化が進み、コンクリートが粗密であったが、注入プラグの取り付けを容易に行う事ができた。
ひび割れ部の注入補修などでは、下方から上方への低圧注入が原則である。
本製品は、注入プラグ本体をテーパー型とし、先端にアメゴムチューブを取り付け、テーパー型注入プラグを削孔穴に挿入することにより、アメゴムチューブを拡張させ密着固定した。
テーパー型プラグにガラス質を混入し成形したことにより、アメゴムチューブとテーパー型プラグをケイ酸アルカリ水溶液に浸してから挿入することにより、先に潤滑剤として機能し、後に接着剤として機能する。
本製品は、テーパー型に成形し、挿入型であるためコンクリートが濡れていても取り付けることができる。一方、注入量管理では，注入プラグがプラスチックにガラス質を混入し半透明としたため、注入材の流入状況を目視確認することができるようになった。
In the water stoppage of fire prevention water tanks due to the earthquake disaster, the concrete frame was aged and the concrete was dense, but the injection plug could be easily attached.
In principle, low-pressure injection from the bottom to the top is used for repairing cracks.
In this product, the injection plug body is tapered, and a candy rubber tube is attached to the tip, and the tapered injection plug is inserted into the hole, thereby expanding and fixing the candy rubber tube.
By forming the taper type plug by mixing glassy material, the candy rubber tube and the taper type plug are immersed in an alkali silicate aqueous solution and then inserted, thereby functioning as a lubricant first and functioning as an adhesive later.
This product is molded into a taper mold and can be attached even if the concrete is wet because it is an insertion mold. On the other hand, in the injection amount management, the injection plug is made translucent by mixing glass with plastic, so that the inflow state of the injection material can be visually confirmed.
