Zusammenfassung:To construct a concrete form device for a tunnel lining concrete molding in a short period of time.SOLUTION: A rear wall divider 21b, which constitutes a side wall 21 of a gantry 12, is installed on both sides of a tunnel, and a beam material 22 is stretched between upper parts of the rear wall dividers 21b. Next, a top form 31 is installed on an upper part of the beam material 22. Then, a front wall divider 21a is connected to the rear wall divider 21b, and the beam material 22 is stretched between the front wall dividers 21a, and the top form 31 is installed on the upper part of the beam material 22. In this way, a form upper body 15 is assembled. Next, the form upper body 15 is raised by a side jack 42 to attach legs to a lower part of the form upper body 15, and then the side jack 42 is removed.SELECTED DRAWING: Figure 17 【課題】トンネル覆工コンクリート成形用のコンクリート型枠装置を短期間で構築すること。【解決手段】ガントリ12の側壁21を構成する後部壁分割体21bをトンネルの両側に設置するとともに、その後部壁分割体21bの上部間に梁材22を架設する。次いで、梁材22の上部に天フォーム31を設置し、その後、後部壁分割体21bに前部壁分割体21aを連結するとともに、その前部壁分割体21a間に梁材22を架設し、その梁材22の上部に天フォーム31を設置する。このようにして、型枠上部体15を組み立てる。次いで、サイドジャッキ42によって型枠上部体15を上昇させて、型枠上部体15の下部に脚を取付け、その後、サイドジャッキ42を撤去する。【選択図】図17
