By using paper materials that are easy to handle as a substitute for the steel and wood materials conventionally used as temporary construction materials, the burden on workers can be reduced and the productivity of temporary construction will improve. The paper material mainly used as the temporary construction materials are HiPLE-ACE®(*1) of Oji Interpack co., Ltd. and Hatosheet(*2) of Oji Kinocloth Co., Ltd*1) HiPLE-ACE®A corrugated board material with a three-layer structure used as a packing material for heavy loads, having a high shock absorption performance and high strength.(*2) HatosheetA nonwoven fabric that uses wood pulp as its main material, capable of controlling the diffusibility, retentivity, and volatility of the liquid it absorbs.
