The building which has the floor lower airtightness structure and the said floor lower airtightness structure of the building

摘要

Topic The inner wall surface of the floor lower spatial territory of the fundamental structure where base and the like of the building occupies lower part and base the whole inside, it makes the airtightness structure due to actual place foaming operation, it makes the moistureproof effect show which especially is superior, collectively the adiabatic effect, insect proof (the anti ant) it offers the floor lower airtightness structure of the building which can make the effect show.SolutionsAs for floor lower airtightness structure, as with land 2 the floor lower spatial territory 3 is worked out with lower part of the base 22 and the like, in the building 21 which was constructed on the land floor lower airtightness structure 11 for fundamental structure such as concrete of the building which provides the bleeder 6 which makes the floor lower spatial territory 3 the air communicate 1, foundation processing material the hammer nose bushing the floor lower space of fundamental structure such as 13 which blocks 12 for moistureproofing which 2 in the whole land inside fundamental structure such as concrete 1 lays and bleeder 6 from spatial territory 3 side under the floors and concrete 1It possesses with the hard urethane foam layer 14 due to the inner wall surface which faces to the territory 3 and the actual place foaming operation which surface in the whole board of hammer nose bushing 13 is provided, and the whole surface of foundation processing material 12.
