Abstract

Provided is a ventilation member suitable for ensuring the ventilation of a ventilation layer provided on the back side of a wall material. A ventilation member X according to the present invention is a ventilation member that can be attached to a wall material, and includes a fixed plate portion 10, a top plate portion 20, a partition plate portion 30, a bottom plate portion 40, a front plate portion 50, and a first baffle plate portion 61. The fixed plate portion 10 has a first surface that abuts against a building framework, and a second surface on a side opposite to the first surface, and includes a first end portion 13 located on one side in a state in which the ventilation member X is attached to the wall material, and a second end portion 14 located on another side. The top plate portion 20 extends from the first end portion 13 of the fixed plate portion 10 on the second surface side. The partition plate portion 30 extends from the top plate portion 20 in a direction from the first end portion toward the second end portion of the fixed plate portion 10. The bottom plate portion 40 extends from the partition plate portion 30 in a direction away from the fixed plate portion 10. The front plate portion 50 extends from the bottom plate portion 40 in a direction from the second end portion toward the first end portion of the fixed plate portion 10. The first baffle plate portion 61 extends from the front plate portion 50 to the partition plate portion 30 side. The bottom plate portion 40 has a first hole 42. A wall material construction structure Y1 according to the present invention includes such a ventilation member X.

First claim

The invention claimed is:

1. A ventilation member configured to be attached to a wall material, comprising:
a fixed plate portion having a first surface that abuts against a building framework, and a second surface on a side opposite to the first surface, and including a first end portion located on one side in a state in which the ventilation member is attached to the wall material, and a second end portion located on another side;
a top plate portion extending from the first end portion of the fixed plate portion on the second surface side;
a partition plate portion extending from the top plate portion in a direction from the first end portion toward the second end portion;
a bottom plate portion extending from the partition plate portion in a direction away from the fixed plate portion;
a front plate portion extending from the bottom plate portion in a direction from the second end portion toward the first end portion; and
a first baffle plate portion extending from the front plate portion to the partition plate portion side,
wherein the fixed plate portion, the partition plate portion, and the top plate portion define a first opening into which an end portion of the wall material is configured to be inserted,
the partition plate portion, the front plate portion, and the bottom plate portion define a second opening that is open in a direction opposite to a direction in which the first opening is open, and
a first hole is located in the bottom plate portion and a second hole is located in the partition plate portion.

2. The ventilation member according to claim 1 ,
wherein the top plate portion is inclined in a direction from the first end portion toward the second end portion, from the fixed plate portion to the partition plate portion.

3. The ventilation member according to claim 1 ,
wherein the bottom plate portion is inclined in a direction from the first end portion toward the second end portion, from the partition plate portion to the front plate portion.

4. The ventilation member according to claim 1 ,
wherein the first baffle plate portion is located on a side of the top plate portion opposite to the bottom plate portion.

5. The ventilation member according to claim 1 ,
wherein the first baffle plate portion is inclined in a direction from the first end portion toward the second end portion, from the front plate portion to the partition plate portion side.

6. The ventilation member according to claim 1 , comprising
a third baffle plate portion extending from the top plate portion toward the second opening side.

7. The ventilation member according to claim 1 , comprising,
inside the first opening, a waterproofing member in abutment against the top plate portion.

8. The ventilation member according to claim 1 , wherein the first hole located in the bottom plate portion and the second hole located in the partition plate portion define a single hole.

9. The ventilation member according to claim 1 , comprising
a second baffle plate portion extending from the first end portion of the fixed plate portion toward a direction from the second end portion toward the first end portion.

10. The ventilation member according to claim 9 ,
wherein the second baffle plate portion is inclined to the top plate portion side relative to an extension surface of the fixed plate portion.

11. A wall material construction structure comprising:
a building framework;
a first wall material; and
the ventilation member according to claim 1 ,
wherein the fixed plate portion of the ventilation member is fixed to the building framework in a state in which the first surface is in abutment against the building framework,
an end portion of the first wall material is inserted into the first opening of the ventilation member in a state in which the end portion is spaced apart from the partition plate portion,
a first ventilation layer extending in an up-down direction along the first wall material is formed on the building framework side of the first wall material, and
the first opening and the second opening are in communication with the first ventilation layer.

12. The wall material construction structure according to claim 11 , comprising:
a second wall material located above the first wall material and attached to the building framework; and
a flashing member,
wherein the flashing member includes:
a flashing fixed plate portion fixed to the building framework, above the fixed plate portion of the ventilation member;
a flashing inclined plate portion inclined downward from the flashing fixed plate portion so as to extend beyond a space between the first wall material and the second wall material; and
a flashing plate portion extending downward from a lower end of the flashing inclined plate portion, and being abutment against a surface of the front plate portion of the ventilation member that is on a side opposite to the first baffle plate portion,
a ventilation space is formed between the second wall material and the flashing inclined plate portion of the flashing member, and
a second ventilation layer extending in the up-down direction along the second wall material and being in communication with the ventilation space is formed on the building framework side of the second wall material.

13. The wall material construction structure according to claim 12 ,
wherein the flashing plate portion extends below a lower end of the front plate portion of the ventilation member from the lower end of the flashing inclined plate portion.
