手間を要する問題がある。[0004] Also, the method of spreading the ground sheet is as follows.
Since the ground sheet has little heat insulation, it has only an effect of defrosting and is ineffective at preventing freezing. In addition, the ground sheet requires not only manual labor and time and effort to deploy it neatly at a desired place at the time of use, but also requires manual labor and time and effort to remove the ground sheet in a state where it can be easily deployed for the next use.

合樹脂の発泡板をいう。As the synthetic resin flexible foam plate 1, for example, a foam plate of polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polystyrene, or a mixed resin containing these can be used. Among these, a polyethylene or polypropylene foam plate is preferable because it can easily satisfy the apparent density and the flexural modulus described later at the same time. Here, the polyethylene or polypropylene foam board refers to a foam board of polyethylene or polypropylene alone, a copolymer containing 50% by weight or more of polyethylene or polypropylene, and a foam board of a mixed resin.

０ｇ／ｃｍ3 である。The synthetic resin soft foam board 1 needs to have an apparent density of 0.007 to 0.025 g / cm 3 . By setting the apparent density in this range, it is possible to obtain an antifreezing curing mat having a good workability with a weight that is easy to lift and little deflection due to its own weight when lifting. If the apparent density exceeds 0.025 g / cm 3 , the weight increases, and the material tends to bend under its own weight when being lifted, resulting in poor handling characteristics and poor workability. In addition, the apparent density is 0.007 g / c.
If it is less than m 3 , the weight becomes too light, and it is easy to be blown off by wind when laying or after laying, and it is difficult to obtain good workability. Preferred apparent density is 0.010-0.02
0 g / cm 3 .

５〜１５ｋｇ／ｃｍ2 である。The synthetic resin flexible foam plate 1 satisfies the above apparent density and has a flexural modulus of 2 to 25 kg / cm 2.
It is necessary to be. By setting the flexural modulus in this range, it fits easily into the unevenness of the ground surface and easily covers the ground surface. The anti-freezing curing mat which is easy to handle and has a small bending due to the above. Flexural modulus 2k
If it is less than g / cm 2 , the rigidity is small, and when it is lifted, it is largely bent by its own weight, and the handling property is likely to be deteriorated. If the flexural modulus exceeds 25 kg / cm 2 , the rigidity becomes too large and the flexibility is insufficient, and it is impossible to follow the unevenness of the ground surface, so that a large gap is generated between the ground surface and the antifreezing and curing effect. Tends to decrease. The preferred flexural modulus is 5 to 15 kg / cm 2 .

It needs to be で 100 mm. 10mm thick
If it is less than the required bending strength, it is difficult to maintain the required bending strength, and the heat insulating property becomes insufficient. When the thickness exceeds 100 mm, the bending strength and the heat insulating property are improved, but the weight is increased, the bulk is increased, and the workability is reduced. Preferred thickness is 15 to 50 mm
It is.

As a result, in the outer periphery of the freezing-preventing curing mat, the ground surface in an area about 20 cm inside from the edge was frozen, and the tee could not be made. Also, the time required for laying out and withdrawing was about 20% longer than in Example 2.
