FORMWORK TAPE, CONCRETE FORMWORK STRUCTURE, AND METHOD FOR PRODUCING CONCRETE BUILDING
To provide a formwork tape that can suppress the generation of burrs, sand streaks, and white flowers in the concrete after curing even when used in construction sites that may be exposed to wind and rain, and have good workability when removed.SOLUTION: It is the tape 10 for formwork constructed in the clearance gap S of the concrete formwork structure 100, and it comprises an adhesive layer 1 adhered to the side surface 21 of the formwork panel 20 which is the basic structure of the concrete formwork structure 100, a water-absorbing layer 2 laminated on the adhesive layer 1 and absorbing the moisture of the concrete from the cross-sectional direction X, and a water-stopping layer 3 that is laminated on the side facing the adhesive layer 1 with the water-absorbing layer 2 interposed therebetween, and prevents rainwater from entering the water-absorbing layer 2 from the thickness direction Y.SELECTED DRAWING: Figure 1
【課題】風雨に晒される可能性のある建築現場での使用でも、硬化後のコンクリートにおけるバリ、砂スジ、白華の発生を抑制することができ、撤去時の作業性が良好な型枠用テープを提供する。【解決手段】コンクリート型枠構造体１００の隙間Ｓに施工される型枠用テープ１０であって、コンクリート型枠構造体１００の基本構造である型枠パネル２０の側面２１に貼着される粘着層１と、粘着層１に積層され、断面方向Ｘからコンクリートの水分を吸収する吸水層２と、吸水層２を挟んで粘着層１と対向する側に積層され、吸水層２への厚み方向Ｙからの雨水の浸入を防ぐ止水層３とを備える。【選択図】図１
