| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a fire-resisting coating for segments easily at low construction cost even when the segments are made of concrete or steel plates.SOLUTION: A fire-resisting mortar holding member 1 is formed of a single flexible plate, and includes a plurality of ribs and also includes a mesh provided between the ribs. The mesh has a plurality of through holes formed successively. A fire-resisting construction method for tunnel includes a first process of fitting segments to a tunnel; a second process of fitting the fire-resisting mortar holding member 1 to a segment fitted to the tunnel after the first process; and a third process of making the fire-resisting mortar holding member 1 holds fire-resisting mortar after the second process. |
