Description

  The present invention relates to a foundation packing disposed between a foundation of a building and a foundation, and relates to a long foundation packing of a subfloor ventilation type.

  In recent years, construction methods in which foundation packing is laid between a foundation and a base are widely used in building construction methods. As this type of foundation packing, a vent hole that penetrates the foundation packing is provided in a width direction orthogonal to the laying direction (one direction) of the foundation packing, and ventilation between the floor and the outside of the building is intended through the vent hole. There is something like that.

  On the other hand, in the vicinity of the outside where the foundation packing is placed, there is a draining member that has the function of preventing the intrusion of rainwater, and in the outer wall ventilation method, the ventilation layer on the inner side of the outer wall material (siding) contains small animals such as pupae and creatures such as insects. An intrusion prevention member (anti-bacterial member or insect-repellent member) for preventing intrusion, a support member (for example, a starter) that supports and positions the lower end position of the outer wall material or outer wall base material, and is applied to the outer surface of the foundation Functional members for constructing a building such as a mortar stopper for finishing mortar are also attached. However, when these functional members are attached using a ventilation-type foundation packing, the ventilation performance of the foundation packing should not be blocked by reducing the ventilation performance, and the attachment position is limited.

  For example, in Patent Document 1, a plurality of guide members protruding upward from the upper surface of the foundation packing body are integrally formed on the side surface of the foundation packing body with a predetermined interval in the longitudinal direction of the foundation packing. It describes the basic packing. The guide member in the basic packing is configured so that the drainage member and the outer wall base material are aligned in the height direction by contacting the drainage member and the outer wall base material from below. Further, the guide member is formed so as to protrude from the side surface region of the base packing in which the vent hole is not formed, and is arranged so as not to hinder the ventilation of the vent hole.
