Even if the hardness of the ground is a small value such as an N value of 3, for example, sufficient durability as a foundation can be ensured. In the case of applying to a ground having an N value of about 3, the ground contact member is, for example, a square of 1.5 m square.
  • the length of the pile is set to around 1m or 2m
  • the area of the ground contact member is the cross section of the pile and the hardness of the ground
  • the weight of the house unit etc. Determined in relation to The ground may not have sufficient strength as a place to set up a temporary housing in a disaster-affected area such as an earthquake-affected area, and the construction of the base was difficult with the conventional method, but the basic structure of the present invention is adopted Therefore, even soft ground can be installed. It will not fall over due to the sinking of the house unit to the ground or the overturning moment acting on the foundation.
  • by reducing the base weight and simplifying the structure of the base construction becomes easier.
  • the fixed position of the pile member with respect to the ground contact member may not be the position corresponding to the central portion of the ground contact member. Moreover, the position of a pile member and a connection member may be shifted. Since the positioning base can ensure a large ground contact area, the area supporting the vertical load can be enlarged to improve the installation stability of the house unit. Moreover, it becomes possible to install a house unit stably corresponding to the level
