CONSTRUCTION METHOD OF RESIDUAL FORM TO PREVENT SALT DAMAGE AND FROST DAMAGE OF PRECAST RESIDUAL FORM PANEL
To provide a method for constructing a residual form in which the residual form can be stably maintained for a long period of time and the appearance of the residual form is prevented from being impaired.SOLUTION: A construction method of a residual form comprises a step of applying a paint having a waterproof function so as to cover an entrance 9a of the capillary gap formed on a back surface 2a of a panel main body 2 and a laitance layer L, a step of constructing residual form 10 using a panel 1 provided with an isolation coating film 4 on the back of panel body 2, and a step of casting and hardening concrete 12 on the back of panel 1. The back surface 2a of the panel body 2 and the concrete 12 are not fixed by the isolation coating film 4, the occurrence of cracks in the panel body 2 is suppressed after the construction, and infiltration of rainwater or saltwater eluted from the snow-melting agent into the capillary gap 9 of the panel body 2 is prevented. Thus, the panel 1 is prevented from frost damage and salt damage.SELECTED DRAWING: Figure 1
【課題】残存型枠を長期間、安定して維持できることに加え、残存型枠の外観が損なわれることを回避する残存型枠の施工方法を提供する。【解決手段】残存型枠の施工方法は、パネル本体２の背面２ａに形成された毛細管空隙の入り口９ａとレイタンス層Ｌを覆うように、防水機能を有する塗料を塗布し、パネル本体２の背面に隔離塗布膜４を設けたパネル１を用いて、残存型枠１０を構築し、パネル１の背面に、コンクリート１２を打設し、硬化させる。そして、隔離塗布膜４により、パネル本体２の背面２ａとコンクリート１２とが固着されないと共に、施工した後に、パネル本体２にひび割れが生じることが抑止され、侵入した雨水や融雪剤から溶出した塩水が、パネル本体２の毛細管空隙９へ浸水することを防止することで、パネル１の凍害や塩害を抑止する構成をとる。【選択図】図１
