【発明の詳細な説明】
本発明はクラツクの補修方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a crack repair method.
コンクリートや石、レンガ等の構築物に生じた
クラツクに、液状乃至グリス状の接着剤を圧入し
てこれを補修することが行なわれている。 BACKGROUND OF THE INVENTION Cracks that occur in structures made of concrete, stone, bricks, etc. are repaired by press-fitting liquid or grease-like adhesives.
この接着剤の圧入に際しては、クラツクの状態
や接着剤の種類によつて、高圧・高速で注入する
場合と、低圧・低速で注入する場合とがあるが、
前者の場合は作業時間が短かくて作業能率も良い
が、後者の場合には、作業時間が長くかかつて作
業能率が悪いばかりか、補修個所が多い（クラツ
クの延べ長さが長い）と多数の注入作業者を必要
とし、更には構築物の高所での作業となると、寒
さや暑さによつて作業者の健康を害することが
往々にしてあつた。 When press-fitting this adhesive, depending on the condition of the crack and the type of adhesive, it may be injected at high pressure and high speed, or it may be injected at low pressure and slow speed.
In the former case, the work time is short and the work efficiency is good, but in the latter case, the work time is long, the work efficiency is poor, and there are many parts to repair (the total length of the crack is long). Furthermore, when working at high places on structures, the health of the workers was often compromised due to the cold or heat.
本発明は、低圧・低速の接着剤注入作業におけ
る上記の問題を解決して、低圧・低速の注入作業
であつても、作業を合理的に行なうと共にその時
間を短縮できるようにすることを課題としたもの
である。 An object of the present invention is to solve the above-mentioned problems in low-pressure, low-speed adhesive injection work, and to enable the work to be performed rationally and to shorten the time even in low-pressure, low-speed adhesive injection work. That is.
この技術課題を解決するために、本発明では、
コンクリート等の構築物に発生したクラツクを補
修するに際し、クラツク上に適宜の間隔をあけて
シールを施こすと共に未シール個所に注入用パイ
プを固設し、あらかじめ接着剤を吸入乃至充填し
た注入器のノズルを注入用パイプに連通せしめ、
注入器のプランジヤーをゴム条帯の弾性を利用し
て継続的に前進せしめてクラツク内へ接着剤を
徐々に圧入することを技術的手段としたものであ
る。 In order to solve this technical problem, in the present invention,
When repairing cracks that have occurred in structures such as concrete, seal the cracks at appropriate intervals, fix an injection pipe in the unsealed area, and use a syringe that has been injected or filled with adhesive in advance. Connect the nozzle to the injection pipe,
The technical means is to continuously advance the plunger of the syringe using the elasticity of the rubber band to gradually force the adhesive into the crack.
この技術的手段によれば、シール及び注入パイ
プの固定工程は、従来のシールや注入口形成工程
に比べて作業能率の点では変化はみられないが、
ノズルをパイプにセツトするだけで、あとはゴム
の弾性を利用して自動的に接着剤がクラツクに注
入されてゆくため、作業者が長時間に亘つて接着
剤注入ガンを保持したまま注入作業をする必要が
なくなり、作業者の健康を害することはない。 According to this technical means, the seal and injection pipe fixing process does not change in terms of work efficiency compared to the conventional seal and injection port forming process, but
Simply set the nozzle on the pipe and the adhesive will be automatically injected into the crack using the elasticity of the rubber, allowing the worker to hold the adhesive injection gun for long periods of time during the injection process. There is no need to do this, and there is no danger to the health of the workers.
また、クラツク上に同時に多数の個所で注入す
ることが可能となり、作業者の数も少なくでき、
しかも短時間で能率よく注入作業が終えられる訳
である。 It also makes it possible to inject at many points on the crack at the same time, reducing the number of workers.
Moreover, the injection work can be completed efficiently in a short time.
また、
(1) 注入器に接着剤をあらかじめ吸入させるた
め、接着剤混合器や充填器等の重い機材をクラ
ツク個所まで運搬乃至持上げる必要がない、
(2) 接着剤はその注入量をあらかじめ設定するこ
とができ、しかも残留量が極めて僅かであるた
め、接着剤のロス率はきわめて小さい、
(3) 追加注入等によつて残留量が生じても、注入
器の容量から計算したり或いは注入器に目盛り
を付けておくなどすれば、注入量を正確に把握
することができる、
(4) 注入器をポリプロピレンやポリエチレン製に
すれば、注入器を何度でも利用することができ
る、
(5) 注入が終つてもゴム条帯に弾力があるために
押圧力を維持し、接着剤が逆流してくることも
なく、安心して注入作業を行なうことができ
る、
等の効果を持ち、極めて実用的且有効な補修方法
である。 In addition, (1) the adhesive is sucked into the syringe in advance, so there is no need to transport or lift heavy equipment such as adhesive mixers and fillers to the crack location; (2) the amount of adhesive to be injected can be determined in advance; (3) Even if a residual amount occurs due to additional injection, it can be calculated from the capacity of the syringe or (4) If the syringe is made of polypropylene or polyethylene, the syringe can be used over and over again. 5) Even after injection is finished, the elasticity of the rubber strip maintains the pressing force, and the adhesive does not flow back, allowing the injection work to be carried out with peace of mind. This is a practical and effective repair method.
次に、上記技術的手段の実施例について、図面
を用いて説明する。 Next, an example of the above technical means will be described using the drawings.
