UNDERFLOOR VENTILATION SPACER

摘要

PROBLEM TO BE SOLVED: To provide an underfloor ventilation spacer which can be adapted to difference in intervals of anchor bolts to be inserted into bolt inserting holes, and fluctuations in implantation position in the width direction of a foundation, and which is not displaced from the foundation and a sill, once fastened and fixed by means of the anchor bolt. SOLUTION: This underfloor ventilation spacer 10 is composed of a thick plate-shaped resin which is equipped with insertion holes 1a for a pair of or a plurality of pairs of anchor bolts to be inserted in a thickness direction. The spacer 10 is interposed between the foundation 2 and the sill 3 so as to form a ventilation gap between the foundation 2 and the sill 3. The insertion holes 1a for the pair of or the plurality of pairs of anchor bolts are axisymmetrically formed in an almost truncated chevron shape. COPYRIGHT: (C)2005,JPO&NCIPI
