According to the first aspect of the present invention, since the entire surface of the inside and outside of the foundation of the cut portion penetrating the inside and outside of the foundation is covered with the intrusion prevention member, ventilation is secured while preventing small animals from invading from outside to inside of the foundation. And
Moisture inside the foundation does not stay behind. In addition, since the cut portion is provided at the upper end of the rising portion, the formation of the cut portion does not affect the reinforcement of the rising portion. Therefore, it is necessary to provide complicated reinforcement such as reinforcing the opening to the reinforcement of the rising portion. Absent. Therefore, not only can it be constructed easily, but also the cut portions can be provided at narrow intervals, and there is no dead space for ventilation.

Since the cut portion is formed, the intrusion prevention member is engaged with the cut portion and does not come off in the thickness direction of the rising portion. Therefore, after fitting the intrusion prevention member into the notch from above the notch, the intrusion prevention member does not fall out in the vertical direction only by installing the building body on the notch. Therefore, construction can be performed reliably.

Nature can be secured. In addition, since each ventilation path has a predetermined length in the thickness direction of the rising portion, compared with the case where the intrusion prevention member is formed of a net, small animals and the like break through the intrusion prevention member and pass through the inside of the foundation. Therefore, invasion of small animals and the like can be reliably prevented. Further, sufficient rigidity for use can be ensured without providing a frame or the like around the ventilation path, so that it can be manufactured at low cost.
