PROBLEM TO BE SOLVED: To prevent the drop of water droplets from a ceiling of a concrete curing chamber by attaching a ceiling lined panel in which waterproof ventilating films are accumulated on one face of a foaming body between a ceiling plate of the curing chamber and it at an interval. SOLUTION: A ceiling lined panel 1 for concrete curing chamber formed by accumulating waterproof ventilating films 3 on one face of a thermoplastic resin foaming body 2 having a cavity rate of a cavity communicated with front and rear of 2% or more and density of 0.01 to 0.2g/m<3> is used. When steam is introduced into the curing chamber, it passes the cavity in the resin foaming body 2 and the water proof ventilating film 3 and reaches a cavity 10 between the ceiling lined panel 1 and a ceiling member 7. Since temperature of the ceiling member 7 is low in the cavity 10, steam is dew-condensed on an indoor face side of the ceiling member 7, becomes water droplets, and drops on the moistureproof ventilating film 3 of the ceiling lined panel 1. It flows toward an end which is lower along inclination provided on the ceiling lined panel 1, drops through a through hole 5 for drain close to a wall on an indoor side, and does not drop on a surface of a concrete product which is being cured. |
