Has been.

  As shown in FIGS. 2 and 4, the packing body 11 is provided with two elastic members 15 and 16. The elastic material 15 is affixed on the upper surface 11a of the packing body 11 by an adhesive at a position overlapping the blocking wall 12b3 in the vertical direction C. The elastic member 16 is attached to the lower surface 11b of the packing body 11 and the lower surface of the blocking wall 12b3 with an adhesive. In more detail, the elastic material 15 is affixed on the upper surface 12b5 of the base | substrate part 12b, and the elastic material 16 is affixed on the lower surface 12b6 of the base | substrate part 12b. These elastic members 15 and 16 extend in the long side direction A over the entire length of the base portion 12b. Further, the constituent materials of the elastic members 15 and 16 are not particularly limited, and examples thereof include a resin material and a rubber material. In addition, when providing the elastic materials 15 and 16 in the packing main body 11, it is good also as using the rubber tape, a urethane tape, a foamed resin tape etc. as the elastic materials 15 and 16 without using an adhesive agent, for example.

  As shown in FIG. 5, the heat insulating material 21 includes a plate-like member 22 extending in the long side direction A, and a plurality of protruding portions 23 protruding in the width direction B from the side surface (one surface) 22 a of the plate-like member 22. Have. The heat insulating material 21 in this embodiment is formed of a foamed resin foam such as a foamed urethane foam, which is a foam-based heat insulating material in which a plate-like member 22 and a plurality of projecting portions 23 are integrally formed. However, any material may be used as long as it is a heat insulating material having elasticity. Moreover, although the plate-shaped member 22 and the some protrusion part 23 are both comprised from the same material, the heat insulating material 21 may be comprised from a mutually different material. In this case, the protrusion 23 should just be comprised from the material which can be elastically deformed. That is, the protrusion part 23 should just be comprised so that elastic deformation is possible.

  Moreover, the heat insulating material 21 has the protrusion part 23 by the same number as the cavity part 12b4 formed in the base | substrate part 12b. The plurality of protrusions 23 are arranged side by side in the long side direction A corresponding to the arrangement of the plurality of hollow portions 12b4. Further, as shown in FIG. 4, the protruding portion 23 has a size slightly larger than the cavity portion 12 b 4, but has a size that can be inserted into the cavity portion 12 b 4 by compressing and elastically deforming. . In this manner, the heat insulating material 21 is inserted into the corresponding cavity 12b4 in a state in which each protrusion 23 is compressed and elastically deformed, and is attached to the packing body 11.

  As shown in FIG. 6, such a foundation packing 10 is disposed between the foundation 1 and the base 2 so that the base portion 12a is disposed on the outdoor side and the base portion 12b is disposed on the indoor side. At this time, the elastic material 15 is compressed between the packing body 11 and the base 2. The elastic material 16 is compressed between the packing body 11 and the foundation 1. The elastic members 15 and 16 are arranged at a position overlapping the blocking wall 12b3 in the vertical direction C, and are formed over the entire length in the long side direction A of the packing body 11. For this reason, it is possible to effectively prevent the outdoor space and the underfloor space S from communicating between the packing body 11 and the foundation 1 and between the packing body 11 and the base 2. For this reason, the airtightness of the underfloor space S can be more effectively ensured.

  At this time, a heat insulating material 21 is attached to the packing body 11. The protruding part 23 of the heat insulating material 21 is inserted into the cavity part 12b4 in a state of being compressed and elastically deformed. Since such a heat insulating material 21 is attached to the packing main body 11, it becomes possible to improve the heat insulating property of the basic packing 10.

  Further, the lower surface 11b of the packing body 11 is constituted by the lower surfaces of the plurality of protruding pieces 12a2, 12b2, 13b and the blocking wall 12b3, and the area covering the upper surface of the foundation 1 is reduced. For this reason, moisture and the like are easily diffused from the upper surface of the foundation 1. As indicated by the arrows in FIG. 6, moisture diffused from the foundation 1 to the anchor bolt hole 14 and the cavity 13c of the connecting portion 13 can be released to the outside through the ventilation portion 12a3. Naturally, the moisture diffused from the foundation 1 to the ventilation part 12a3 can be released to the outdoors. In addition, since the heat insulating material 21 is inserted into the cavity portion 12b4, moisture is hardly diffused from the portion facing the cavity portion 12b4 of the foundation 1 to the cavity portion 12b4, but the portion facing the anchor bolt hole 14 of the foundation 1 Since the moisture is easily dissipated as described above, the moisture in the portion of the foundation 1 facing the cavity 12b4 moves toward the anchor bolt hole 14 and is dissipated into the anchor bolt hole 14. Moreover, even if the moisture of the base 2 is dissipated into the anchor bolt hole 14 from the portion facing the anchor bolt hole 14 of the base 2, the moisture can be released to the outside through the ventilation portion 12a3 as described above.

  As described above, according to the foundation packing 10 of the present embodiment, the foundation packing 10 is disposed between the foundation 1 and the base 2 so that the base portion 12a is disposed on the outdoor side and the base portion 12b is disposed on the indoor side. By being arranged, from the base portion 12a to the blocking wall 12b3 including the space surrounded by the pair of base portions 12a, 12b and the plurality of connecting portions 13 (that is, the space constituted by the anchor bolt holes 14). A space (a space constituted by the hollow portion 13c and the anchor bolt hole 14) communicates with the outdoors via the ventilation portion 12a3. For this reason, it becomes possible to dry the upper surface of the foundation 1 and the lower surface of the base 2 while keeping the underfloor space S isolated from the outside and airtight.

  In addition, the blocking wall 12b3 is disposed inward in the width direction B from the outer end of the base portion 12b. Thereby, for example, even if the base 2 is slightly displaced toward the base portion 12a side (outdoor side) and disposed on the foundation packing 10, the blocking wall 12b3 and the base 2 are easily disposed so as to overlap in the vertical direction C. For this reason, the airtightness of the underfloor space can be ensured. If the base portion 12b does not have the top plate 12b1 and the blocking wall 12b3 is disposed at the outer end of the base portion 12b, if the base 2 slightly shifts to the outdoor side as described above, the blocking wall 12b3 and The base 2 does not overlap with the vertical direction C, and the space on the outdoor side and the underfloor space S are more easily communicated with each other than the blocking wall 12b3.

  Further, the blocking wall 12b3 is arranged at the inner end of the base portion 12b in the width direction B. Thereby, even if the base 2 is slightly displaced to the base portion 12a side (outdoor side) and arranged on the foundation packing 10, the blocking wall 12b3 and the base 2 are more easily arranged in the vertical direction C. For this reason, the airtightness of the underfloor space S can be effectively ensured.

  Further, since the plurality of hollow portions 12b4 are formed in the base portion 12b, the basic packing 10 can be reduced in weight and the amount of raw materials used can be reduced. Further, the weight of the base portion 12b can be brought close to the weight of the base portion 12a, the weight balance between the base portion 12a and the base portion 12b can be achieved, and the packing and construction work of the base packing 10 can be easily performed.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made as long as they are described in the claims. For example, the pair of base portions 12a and 12b of the foundation packing 10 in the above-described embodiment does not have a bottom plate, but may have a bottom plate having the same shape as the top plates 12a1 and 12b1. In this case, each ventilation part 12a3 becomes a hole penetrating the base part 12a in the width direction B. The ventilation part 12a3 may have any opening shape, and it only has to penetrate the base part 12a in the width direction B.

  The blocking wall 12b3 may be disposed between the inner end portion and the outer end portion of the base portion 12b and at the outer end portion of the base portion 12b. In the base part 12b not provided with the bottom plate, the closer the blocking wall 12b3 is to the outer end of the base part 12b, the more easily moisture released from the upper surface of the foundation 1 is released to the outdoors.

  The heat insulating material 21 may not be attached to the packing body 11. Further, the elastic members 15 and 16 may not be provided on the packing body 11. Further, only the elastic material 15 may not be provided on the packing body 11.
