  On the upper surface portion 61 of the parting edge 6, a substantially V-shaped groove 61 a that is recessed downward is formed substantially at the center. The groove 61a corresponds to the shape and arrangement position of the rib 32a of the bent portion 32 in the ventilation member 1 illustrated in FIG.

  FIG. 3A is a cross-sectional view illustrating a state before the ventilation member illustrated in FIG. 1 is attached.

  A plurality of trunk edges 7 are attached and fixed to the wall base H by fixing tools F1 and F2. Adjacent trunk edges 7 are arranged at a predetermined interval, and the space between the trunk edges 7 functions as a ventilation space W. The parting edge 6 is attached and fixed to the front surface of the trunk edge 7 with the trunk edge abutting piece 62 in contact therewith. The upper edge 81 of the outer wall material 8 is inserted and fixed inside the parting edge 6, and the front side of the outer wall material 8 is pressed and held by the bent part 63 a of the pressing piece 63 of the parting edge 6. Yes. A gap B is formed between the lower surface of the eaves ceiling R and the upper surface portion 61 of the parting edge 6.

  As a procedure for attaching the outer wall material 8, first, the parting edge 6 is fixed by the fixing tool F1. By adjusting the vertical position of the mounting and fixing of the parting edge 6, the vertical length of the gap B is set to the vertical length of the ventilation member 1 illustrated in FIG. (The length between the bent portion 32 of the portion 3). And the upper end part 81 of the outer wall material 8 is inserted in the inside of this parting edge 6, and the outer wall material 8 is fixed by the fixing tool F2. For example, the fixing tool F2 can be driven in a state in which the pressing piece 63 of the parting edge 6 is spread upward. Thereafter, the pressing piece 63 of the parting edge 6 can be bent and brought into contact with the upper end portion 81 of the outer wall material 8. The vertical position of the outer wall material 8 can be adjusted by adjusting the distance between the outer wall material 8 and the upper surface portion 61 of the parting edge 6. As the outer wall material 8, an inorganic outer wall material such as a cement plate can be used as appropriate in addition to the metal outer wall material.

  FIG. 3B is a cross-sectional view illustrating the attachment state of the ventilation member illustrated in FIG. 1.

  The ventilation member 1 has the eaves ceiling abutting portion 4 in contact with the lower surface of the eaves ceiling R, and the bent portion 32 of the elastic locking portion 3 is in contact with the upper surface portion 61 of the parting edge 6. It is inserted rearward into a gap B between the lower surface and the parting edge 6 disposed at the upper end 81 of the outer wall member 8. When the ventilation member 1 is pushed into the gap B, the ventilation member 1 contracts in accordance with the vertical length of the gap B and is pushed into the gap B by the elastic force of the elastic locking portion 3. . Specifically, for example, deformation such as reduction of the inclination angle of the inclined part 31 of the bullet locking part 3 or reduction of the space between the inclined part 31 and the bent part 32 occurs, and the vertical direction associated with this deformation occurs. The resilience is demonstrated.

  When the ventilation member 1 is inserted into the gap B, the impact of the impact locking portion 3 is at a position where the rib 32a of the bent portion 32 forming the impact locking portion 3 and the groove 61a of the parting edge 6 coincide. The rib 32a of the bent portion 32 and the groove portion 61a of the parting edge 6 are fitted by force. For this reason, the ventilation member 1 can be attached to the gap B by a one-touch method without using a fastener such as a nail. Further, since the ventilation member 1 has the elastic locking portion 3, even if the attachment position of the parting edge 6 disposed on the upper end portion 81 of the outer wall material 8 is somewhat inaccurate, the elastic locking portion 3. The mounting position can be accommodated by the vertical expansion and contraction due to the elastic force of. For this reason, since the high precision is not necessarily requested | required in the attachment operation | work of the parting edge 6, construction is easy. Further, in the ventilation member 1, the elastic locking part 3 is pressed against the parting edge 6 and the eaves ceiling abutting part 4 is pressed against the lower surface of the eaves ceiling R by the elastic force of the elastic locking part 3. Therefore, the water tightness on the lower surface of the eaves ceiling R can be reliably ensured. Further, the decorative portion 5 is formed in a flat shape and hangs substantially vertically, so that it has a good appearance and is easy to process.

  Furthermore, once the rib 32a of the bent portion 32 and the groove portion 61a of the parting edge 6 are fitted to the ventilation member 1, a downward force is applied by the elastic force of the elastic locking portion 3. It is difficult to be released, and the falling off of the ventilation member 1 is suppressed. Furthermore, the eaves ceiling contact part 4 of the ventilation member 1 is provided with a hook part 41 that rises forward. The hook portion 41 does not hinder the insertion of the ventilation member 1, and after the ventilation member 1 is inserted, it comes into contact with the eaves ceiling R and exhibits a so-called maple function. For this reason, the ventilation member 1 once inserted into the gap B is prevented from dropping out of the gap B.

  As illustrated by the arrow in FIG. 3B, generally, in the ventilation space W formed between the trunk edges 7, the air flows along the wall base H from the base side toward the eaves ceiling R. . Then, this air flows from the vent hole 21 of the standing part 2 of the vent member 1 to the exhaust space X of the vent member 1 through the vent gap Y inside the louver 22 and is exhausted from the exhaust hole 51 of the decorative part 5 to the outside. Since the louver 22 is disposed so as to cover the vent hole 21 of the upright portion 2 from the front, the exhaust direction can easily follow the air flow, and the air can be exhausted from the exhaust hole 51 almost straight without stagnation. .

  FIG. 4A is a cross-sectional view illustrating a second embodiment of the ventilation member of the present invention. FIG. 4B is a cross-sectional view illustrating the attachment structure of the ventilation member illustrated in FIG. Portions common to the first embodiment are denoted by the same reference numerals, and description thereof is omitted below.

  The ventilation member 1 is not provided with an exhaust hole in the decorative portion 5, and the eaves ceiling contact portion 4 of the ventilation member 1 is formed longer in the front-rear direction than in the first embodiment. For this reason, the space | interval between the front-end part 31A of the inclination part 31 of the decoration part 5 and the elastic locking part 3 is formed large. As illustrated by the arrow in FIG. 4B, the air flowing in the direction of the eaves ceiling R from the base side through the ventilation space W between the trunk edges 7 flows from the ventilation hole 21 of the standing part 2 into the louver 22. It flows into the exhaust space X of the ventilation member 1 through the gap Y. Subsequently, the air from the exhaust space X is exhausted to the outside through a gap between the decorative portion 5 and the front end portion 31 </ b> A of the inclined portion 31 of the bullet locking portion 3.

  FIG. 5A is a cross-sectional view illustrating a third embodiment of the ventilation member of the present invention. FIG. 5B is a cross-sectional view illustrating the attachment structure of the ventilation member illustrated in FIG. Portions common to the first embodiment are denoted by the same reference numerals, and description thereof is omitted below.

  The decorative portion 5 of the ventilation member 1 includes an inward portion 52 that is bent inward and upward from the lower end. The inward portion 52 is formed so as to come into contact with the pressing piece 63 of the parting edge 6 after the ventilation member 1 is attached. Further, the exhaust hole 51 is provided in a corner portion C extending from the vicinity of the lower end of the decorative portion 5 to the inward portion 52. For this reason, rainwater is difficult to blow into the exhaust hole 51 even by strong winds or the like. Even if rainwater blows into the exhaust hole 51, the rainwater flows downward along the inclination of the inward portion 52 and flows out of the exhaust hole 51, so that the rainwater stays inside the ventilation member 1. It is difficult to prevent the ventilation member 1 from being corroded. The air flowing through the ventilation space W between the trunk edges 7 in the direction from the base side to the eaves ceiling R flows from the ventilation hole 21 of the standing part 2 to the exhaust space X of the ventilation member 1 through the ventilation gap Y inside the louver 22. Then, the air from the exhaust space X is exhausted from the exhaust hole 51 of the decorative portion 5 to the outside.

  FIG. 6A is a cross-sectional view illustrating a fourth embodiment of the ventilation member of the present invention. FIG. 6B is a cross-sectional view illustrating the attachment structure of the ventilation member illustrated in FIG. Portions common to the first embodiment are denoted by the same reference numerals, and description thereof is omitted below.

  The decorative portion 5 of the ventilation member 1 includes an inward portion 52 that is bent inward and upward from the lower end. Further, a wing portion 52a protruding in a substantially right angle direction is formed at the tip of the inward portion 52. The inward portion 52 is formed such that its tip abuts against the presser piece 63 of the parting edge 6. Further, the exhaust hole 51 is provided in a corner portion C extending from the vicinity of the lower end of the decorative portion 5 to the inward portion 52. For this reason, rainwater is difficult to blow into the exhaust hole 51 even by strong winds or the like. Even if rainwater blows into the exhaust hole 51, the rainwater flows downward along the inclination of the inward portion 52 and flows out of the exhaust hole 51. It is hard to get stuck and corrosion of the ventilation member 1 is suppressed. The air flowing through the ventilation space W between the trunk edges 7 in the direction from the base side to the eaves ceiling R flows from the ventilation hole 21 of the standing part 2 to the exhaust space X of the ventilation member 1 through the ventilation gap Y inside the louver 22. Since the wing portion 52a is formed so as to rise in the exhaust space X of the ventilation member 1, the air flow is complicated in the exhaust space X and is exhausted from the exhaust hole 51 of the decorative portion 5 to the outside. For this reason, rainwater is more difficult to blow into the exhaust hole 51.

  FIGS. 7A and 7B are partially enlarged cross-sectional views illustrating another embodiment of the bullet locking portion in the ventilation member of the present invention. The ventilation member of the present invention includes, for example, the forms illustrated in FIGS. 7A and 7B.

  In the form illustrated in FIG. 7A, the bullet locking portion 3 has an inclined portion 31 extending from the lower end of the standing portion 2 toward the rear and obliquely downward. A bent portion 32 is formed by bending forward from the front end of the inclined portion 31. The bent portion 32 is formed substantially horizontally, and a rib 32a protruding downward is provided at a substantially central portion. The rear end of the bent portion 32 is folded upward. Also in this form, the elastic force in the vertical direction by the elastic locking part 3 is exhibited well. For this reason, it is possible to attach the ventilation member 1 by a one-touch type, and it is easy to construct because it can cope with a shift in the attachment position of the parting edge, and water tightness on the lower surface of the eaves ceiling can be secured.

  In the form illustrated in FIG. 7B, in the impact locking portion 3, the first inclined portion 31 a and the second inclined portion 31 b extend from the lower end of the standing portion 2. The first inclined portion 31a extends obliquely downward and forward from the lower end of the upright portion 2. Furthermore, the second inclined part 31b extends rearward and obliquely downward from the front end of the first inclined part 31a. A bent portion 32 extending substantially horizontally toward the front is formed from the rear end portion of the second inclined portion 31b. The bent portion 32 is formed substantially horizontally, and a rib 32a protruding downward is provided at a substantially central portion. The front end of the bent portion 32 is folded upward. Also in the form of the bullet locking part 3 in this manner, the elastic force in the vertical direction is satisfactorily exhibited. The ventilation member 1 can be attached in a one-touch manner, and can be easily constructed because it can cope with a shift in the attachment position of the parting edge, and water-tightness on the lower surface of the eaves ceiling can be ensured.

  The ventilation member and its mounting structure of the present invention are not limited to the above forms. For example, the shape and size of the vent holes and exhaust holes can be appropriately designed. In addition, the shape and size of the hook of the eaves ceiling contact portion and the rib of the bent portion of the bullet locking portion can be appropriately designed. Furthermore, the eaves ceiling abutting portion can be formed to be inclined according to the inclination of the lower surface of the eaves ceiling, and thereby, for example, a ventilation member can be attached below the eaves ceiling of the gable roof.
