Description

  The present invention relates to a foundation finishing fixed tree used in a building in which a foundation packing is installed between a foundation and a foundation, and a foundation finishing method using the foundation finishing fixed tree.

In buildings such as wooden houses, a base packing method (also referred to as a basic packing method) may be employed in order to ensure air permeability under the first floor (refer to Patent Document 1). In the foundation packing method, a plurality of block-shaped members called foundation packings (also called foundation packings) are installed at predetermined intervals between the foundation and the foundation, and vent holes are formed between adjacent foundation packings. It is a construction method that ensures the air permeability of the space. Buildings that use the foundation packing method do not need to form ventilation holes in the foundation, so the cross-sectional defect of the foundation rising part can be eliminated, and there is no contact between the foundation and the foundation, so a moisture-proof sheet is unnecessary. It is possible to ensure the air permeability of the portion where the conventional air permeability such as the corner portion is bad, and it is possible to ensure the air permeability of the portion where the conventional air holes such as the entrance and the terrace could not be formed. Have many advantages.
