The plate member 12 is formed to have a predetermined thickness t (for example, about 30 mm) from the resin plate member 12, and the plate member 12 extends from one end surfaces of the packing body upper member 10 and the lower member 11 in the short direction of the packing body 8. It has a protruding portion, and this portion forms a collar portion 13. The flange 13 has a shape in which the protruding tip side is slightly curved downward. Packing body lower member
A plurality of ventilation paths 15 are provided in the longitudinal direction at a predetermined interval and communicate with the one end face and the other end face facing the short direction. In this embodiment, the air passage 15 is a hole having a perfectly circular cross section, and the hole diameter ψ is about 20 mm. The hole diameter と し た is set to about 20 mm in order to minimize the viscosity of the air flowing through the ventilation path 15 to secure the straightness of the air and to make the air flow smooth. On the other hand, the packing body upper member 10 is provided with an air passage 17 having a semicircular cross section with an upper surface opening, which is cut out from one end face to a predetermined length on the other end face side. Reference numeral 18 denotes a hole for a mounting anchor bolt.

Reference numeral 15 communicates the underfloor with the outside, the flange 13 faces the underfloor, and a ventilation path 17 is installed between the foundation 1 and the base 2 so as to communicate the underfloor with the ventilation hole 6. On the outside of the ventilation path 15 in which the packing 3 is installed, a base drainage member 20 with a rat proof material is installed. The base drainage member 20 has a base end fixed to the other end surface of the packing body upper member 10 and is bent downward so as to cover the ventilation path 15. ) 21 is attached.

出されることになる。In the above construction, the humid outside air passes through the rod-proofing material 21 of the base drainage member 20 and enters the ventilation path 15 of the packing 3 as shown by the arrow A, from which it is guided by the lower surface of the collar portion 13. Into the lower part of the floor, and is temporarily stored below the floor. On the other hand, the sufficiently dried air under the reserved floor enters the ventilation passage 17 from the upper surface of the collar portion 13 as shown by the arrow B, enters the base 2 and the ventilation hole 6 of the wall 5 from there, and rises. The waste gas is discharged from the ventilation hole at the back of the building (not shown).

Therefore, the foundation 1 is strengthened, and the possibility of cracks occurring in the foundation 1 as in the related art is reduced even in the event of an earthquake or the like. In addition, ventilation in the wall is performed by the ventilation path 17, but at this time, mixing of the outside humid air and the dry air under the floor by the rectifying action of the collar 13 is delayed, so that the ventilation hole 6 Because humid air does not flow and only sufficiently dry air flows,
Dew condensation does not occur in the wall 5 or the like.

付して説明を省略することとする。FIG. 3 shows another embodiment of the under-substrate packing. In the packing 3a of this embodiment, the ventilation path 15a is not formed in a perfect circular cross section, but is formed in a rectangular cross section with an opening at the bottom. Such an air passage 15a can be formed by, for example, finely dividing the packing body lower member 11a and attaching it at predetermined intervals, so that it is easier and cheaper to manufacture than the air passage 15. Other configurations are the same as those of the packing 3 of the above-described embodiment, and therefore, the same components are denoted by the same reference numerals but are not described here.

を効果的に行うことができる等の優れた効果がある。According to the first aspect of the present invention, since the under-base packing has the above-described structure, the use of the under-base packing weakens the foundation of the building structure and the wall having the ventilation holes, which have been conventionally proposed. It is possible to alleviate the occurrence of dew condensation in the body and the like and the corrosion of buildings based on the dew condensation at a glance. Since the ventilation device for a building according to the second aspect of the present invention has the above-described configuration, the same effect as that of the first aspect can be expected. Claim 3
Since the ventilating device for a building according to the invention of the present invention has the above-described configuration, it has further excellent effects such as the ability of the rat to effectively enter and drain the ventilation path.
