PROBLEM TO BE SOLVED: To provide a steam curing tank for a concrete product for suitably solving a conventional problem of a crack due to an abrupt change of an atmospheric temperature, by approaching a room temperature in the tank to the atmosphere as fast as possible and then taking out the product from each tank. SOLUTION: The steam curing tank for the concrete product comprises a plurality of curing tanks A1, A2... of a heat insulation structure, a boiler 7 for supplying steam into the tanks A1, A2,..., etc. The steam curing tank houses uncured concrete products in the respective tanks A1, A2..., and fully fills high-temperature steams supplied from the boiler 7 in the tanks A1, A2... to expedite curing. Each tank has a temperature sensor 3 for detecting a room temperature in the tank. Each tank also has an exhaust valve 4 opened or closed according to a temperature detection signal of the sensor 3, and an exhaust fan 5 for exhausting the inner air in the tank when the valve 4 is opened. |
