床の下地合板は厚手のものなので構造材に直接張ることができることから、重いものに耐えられる垂直耐荷重だけでなく、地震の時の水平構造耐力も大きくなります。

雨が降っていいるので床下に水も溜まってしまいますが床合板は数か所剥がせるようにしておいて、屋根ができてから床を剥がして水を吸い取り更には送風機で乾燥させて工事を進めます。

Since the underlying plywood of the floor is thick, it can be stretched directly to the structural material, so not only the vertical load capacity that can withstand heavy things but also the horizontal structural strength at the time of the earthquake will increase.

Water is also collected under the floor because it is raining, so that floor plywood can be peeled off in several places, after the roof is formed peel off the floor and suck up the water and further dry it with a blower to finish construction I will proceed
