い。2. Description of the Related Art In order to improve the quality of concrete and impart the required strength and durability as a structural material,
It is essential to perform sufficient curing during construction. The longer the period of concrete curing, the more improved the strength, durability and watertightness. In particular, it is necessary to sufficiently protect the concrete against temperature changes such as insolation under the heat of summer and low temperatures during the cold season, and it is desirable that the formwork used during placing is not removed for as long as possible.

工として、養生作業を組み入れていた。However, when pouring concrete using a formwork, there is a tendency to remove the formwork as early as possible from the viewpoint of work process restrictions and construction period. If the formwork is removed early, the concrete is directly exposed to the atmosphere, and the quality deteriorates due to temperature changes and drying. So, conventionally,
After removing the formwork, the curing work was incorporated as a separate curing work in order to continue the curing.
【０００４】しかしながら、このような従来の養生方法

て、湿潤状態を維持することができる。In order to achieve the above object, the present invention is to apply a curing sheet to the inner surface of a formwork to pour concrete, and after the set concrete is cured, the formwork is After removing, the method for curing concrete, wherein the curing sheet is left in a state of being adhered to the surface of the concrete, wherein the curing sheet is a heat insulating member arranged at the center, and the heat insulating member is sandwiched between the two surfaces. It was composed of a pair of water-impermeable adhesive films arranged. According to the curing method of the above configuration, after removing the formwork, the curing sheet is left in a state of being adhered to the surface of the concrete, and further, this curing sheet is a heat insulating member arranged in the center, and this heat insulating member. Since it has a pair of water-impermeable adhesive films arranged on both sides of the concrete so as to sandwich it, the concrete is protected from temperature changes such as insolation under the heat and low temperatures during the cold, and at the same time prevents drying. Thus, the wet state can be maintained.

It is composed of The heat insulating member 14a has heat insulating properties and water absorbency, and is made of, for example, fibers such as a woven fabric or a non-woven fabric having a predetermined thickness (about several mm). The adhesive films 14b and 14c are made of a water-impermeable synthetic resin film and are bonded to the heat insulating member 14a with an adhesive.

行われる。When the attachment of the curing sheet 14 to the mold 10 is completed and the mold 10 is supported by the support 12 and installed at a predetermined position, as shown in FIG. Concrete 16 is placed on the inner side of 10. Then, the work of removing the mold 10 is performed at the stage where the cast concrete 16 has hardened to some extent. At this time, the curing sheet 14 is adhered to the surface of the concrete 16 while the mold 10 is peeled off from the adhesive film 14b.

As shown in FIG. 1D, the curing sheet 14 is removed from the surface of the concrete 16. Now, according to the curing method for the concrete 16 configured as described above, the mold 10
After removing the curing sheet, the curing sheet 14 is left in a state of being adhered to the surface of the concrete 16, and the curing sheet 14 is arranged on both sides of the heat insulating member 14a arranged in the center and the heat insulating member 14a. Since it has a pair of water-impermeable adhesive films 14b and 14c that are formed, the concrete 16 is shielded from temperature changes such as insolation under the heat and low temperatures during the cold, and prevents drying, A wet state can be maintained.
