【発明の詳細な説明】
従来、新旧コンクリート構造物の打継ぎには主としてエ
ポキシ系の接着剤が採用されているが、以下述べる様な
問題点が指摘されていた。DETAILED DESCRIPTION OF THE INVENTION Conventionally, epoxy adhesives have been mainly used for joining old and new concrete structures, but the following problems have been pointed out.
（１）エポキシ系接着剤は、材料費が高価でありかつ取
扱時に有機溶剤を用いるために、近辺での火気使用及び
換気等の安全上の考慮が必要である。(1) Since epoxy adhesives are expensive in material cost and use organic solvents when handling, safety considerations such as the use of open flames and ventilation in the vicinity are necessary.
（２）エポキシ系接着剤は、打継面に塗布してから極め
て短時間内に新コンクリートを打設しなければ、その接
着効果が失われると同時に、逆に肌離れ等の原因ともな
るので、作業時間が制限され施工管理が困難である。(2) If epoxy adhesive is not applied to the joint surface and new concrete is poured within a very short time, it will lose its adhesive effect and may even cause peeling. , construction management is difficult due to limited working time.
（３） エポキシ接着剤を打継コンクリート面に塗布
する場合には、下地がある程度乾燥していな（ではなら
ないために、雨天等により施工が制限される。(3) When applying epoxy adhesive to the poured concrete surface, the base must be dry to some extent, so construction may be restricted due to rain or other factors.
（４）接着剤だけでは、鉄筋コンクリート構造物の打継
面では、地震動等に対して不安である。(4) If adhesives are used alone, the joint surfaces of reinforced concrete structures may be susceptible to seismic motion.
以上の点を考慮して
火気、換気等の安全上の考慮を必要とせず、かつ接着剤
を塗布後、数日間放置しても接着効果が変らない、施工
性の良い確実な工法が開発出来ないものかという声が現
場では大であった。Taking the above points into consideration, we have developed a reliable construction method with good workability that does not require safety considerations such as fire and ventilation, and which does not change the adhesive effect even if left for several days after applying the adhesive. There were many voices at the scene asking if it was possible.
本工法は、現場でのその強い要望ｌこ答えて、施工性に
優れかつ確実な工法で解決したものである。This construction method was developed in response to the strong demands on site by providing a method that is both highly workable and reliable.
