Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing portion fixed to a base which is fixed to an upper portion of a base material with a gap therebetween, and communicates the outside of the building with the inner space of the base material through the gap. A connecting portion that forms a communication passage inside and includes a cover portion that prevents rainwater from entering the inner space of the base material from the outside of the building through the gap, and that connects the fixing portion and the cover portion. Relates to a base cover provided with receiving portions for receiving lower end portions of a plurality of vertical furring strips arranged at intervals along the outer wall and the inner wall.

[0002]

2. Description of the Related Art As shown in FIG. 5, a base cover F has a base 1 and a fixing portion 1 which is fixed to a base C which is fixed to an upper portion of a base material B with a gap E therebetween. A communication passage 2 that communicates the building exterior Q and the inner space R of the base material B through a gap E with the base C is formed inside, and the building exterior Q through the gap E to the inner space R of the base material B is formed. A plurality of cover portions 3 for preventing intrusion of rainwater, and a plurality of connecting portions 16 connecting the fixing portion 1 and the cover portion 3 are arranged at intervals along the outer wall A1 and the inner wall A2. Vertical furring H
The receiving part 9 for receiving the lower end of the
By fixing it to the inner space R of the base material B, the lower end portion of the vertical furring strip H can be well received by the receiving portion 9, and the air permeability of the inner space R of the base material B can be secured. It is designed to prevent rainwater from entering, and conventionally, as shown in the figure, the lower portion of the space S between adjacent vertical furring strips H is closed by a connecting portion 16 that connects the fixing portion 1 and the cover portion 3. There is.

[0003]

Therefore, it is difficult to ensure the air permeability of the space between the adjacent vertical furring strips, and the dew condensation water or the like that has condensed in the space easily accumulates at the upper part of the connecting portion, so that the space between the vertical furring strips is increased. There is a defect that molds are generated inside and the vertical furring strip and the base cover are easily corroded. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a base cover in which mold is not generated between the vertical furring strips and the vertical furring strips and the base cover are resistant to corrosion.

[0004]

[Action]

The space between the adjacent vertical furring strips can be communicated with a communication passage that communicates the exterior of the building with the interior space of the foundation material through the communication part provided in the connection part. Moreover, the dew condensation water flowing down from the space between the vertical furring strips through the communication portion is unlikely to flow into the inner space side of the base material through the gap between the base material and the base. [Effect] It is easy to ensure the air permeability of the space between the vertical furring strips, and the condensed water that has condensed in the space does not easily accumulate at the upper part of the connecting part.
It is possible to prevent mold from forming inside the vertical furring strips and corrosion of the vertical furring strips and the base cover. Also, since the space between the vertical furring strips is communicated with the exterior of the building by utilizing the communication passage that communicates the exterior of the building with the inner space of the foundation material, the structure can be simplified compared to the case where a separate communication device is provided. be able to. Further, it is possible to prevent the occurrence of mold and corrosion on the base and the base material.

According to a second aspect of the present invention, the receiving portion receives the lower end portion of the vertical furring strip on the outer wall side and the lower end portion of the inner wall side with a gap therebetween. There is a point that is configured. [Operation] Condensed water is unlikely to stay between the lower end of the vertical furring strip and the receiving portion. [Effect] It is possible to prevent the occurrence of mold and corrosion on the lower end portion of the vertical furring strip and the receiving portion.

[0006]

According to a third aspect of the present invention, there is provided a mesh member for closing the communication passage on the outside of the building with respect to the communication portion. [Operation] While ensuring the air permeability of the inner space of the foundation material and the space between the vertical furring strips, it is difficult for insects and small animals to enter these spaces. [Effect] It is possible to prevent building damage caused by insects and small animals.
