とは難しかった。2. Description of the Related Art Conventional concrete curing methods differ depending on the construction site. For mass concrete, however, a water-retaining mat having a single layer structure is laid on a concrete surface, or cured by directly impregnating or spraying water on the concrete surface. . However, in flooding or watering, it is difficult to flood or water the entire surface, and in order to completely inundate water, it is necessary to stop water at each corner, which takes time and requires concrete work. When the next work after installation and curing was performed, flooding curing was a bad condition for the next work. In addition, when a water-retention mat is laid, the water-retention capacity is determined only by the material of the mat, so that the water-retention mat is often dried unless water is frequently sprayed. Further, the water retention mat often shifts or winds up due to the influence of the wind, and it is difficult to maintain the cured state in the initial stage of laying for several days.

敷き続けることは難しかった。[0003] As a countermeasure against cracking of the temperature of concrete, there is a method in which several air mats having a great effect are laid one on another. However, it required relatively heavy labor, and even if it was weighed, the air mat was very light, so it was still affected by the wind and it was difficult to spread it evenly over the entire surface.

The injected middle layer 3 serves as a weight to prevent the mat from being rolled up by wind or the like, and to infiltrate the lower layer 4 with water through the minute holes 13. The lower layer 4 infiltrated with water retains water uniformly on the entire area to give the concrete 6 an appropriate amount of water. The upper layer 2 enclosing the air has a heat retaining and heat insulating effect. The synergistic effect of the upper, middle, and lower three layers 2, 3, 4 provides the best environment for the hardening action of concrete as the initial curing of concrete.

い。As described above, the three-layer curing mat of the present invention comprises a hollow upper layer containing air, a hollow middle layer for storing water, and a water-retaining lower layer for infiltrating water from the middle layer. In the three-layer structure, the lower layer functions as a water retention mat, the middle layer functions as a water mat that also functions as storage and weight, and the upper layer functions as an air mat that has heat insulation and heat insulation effects. In addition to being able to be continuously immersed in water, it has good heat retention and can be set to a proper curing condition for concrete. In addition, the weight is not required due to the water storage in the middle layer, and since the middle layer can be emptied and brought to the site, handling such as transportation is easy, and in addition, it is connected and laid in a block form, Since it can be laid as a long object from a roll to an appropriate length, the workability of laying is also very good.
