期の保温養生が必要になっている。Conventionally, when a precast concrete member is manufactured in a factory or a construction site, after the concrete is poured into a formwork, an initial stage is required to promote the development of concrete strength so as to enable the demolding process the next day. It is necessary to keep warm.

されている。[0004] In general, heat curing is performed by steam curing. This steam curing is generally accelerated curing using normal pressure steam, and concrete is heated at a constant rate by supplying steam from a steam generator. After a period during which the concrete is kept at the maximum temperature, the supply of steam is stopped and the concrete is cooled to promote the development of concrete strength.
The process of steam curing is usually planned in one cycle per day.

高額になり、したがってプレキャストコンクリート部材
のコストアップの要因にもなっていた。The above-mentioned steam curing method is excellent in that even when many precast concrete members are cured at the same time, the temperature can be uniformly maintained over a wide range, but if the airtightness is not good, the heat efficiency is extremely poor. . Therefore, in addition to the steam generator, it is necessary to provide an enclosure such as a cover with rails, which has a problem that the curing equipment becomes large. In addition, the equipment cost has been increased, and this has also been a factor in increasing the cost of the precast concrete member.
