JP 2009-13678 A Japanese Patent Laid-Open No. 04-202935 JP 2011-32720 A JP 2008-150904 A

  In the conventional ventilation structure such as Patent Document 1, since the ventilation opening is opened substantially downward, intrusion of wind and rain from above and from the side can be prevented, but measures against intrusion of wind and rain from below are insufficient. There was room for improvement in terms of rain performance.

  In addition, the draining material in the prior art disclosed in Patent Documents 2 to 4 and the like is merely for successfully guiding rainwater into the outer cage, and does not improve the rain performance in the ventilation structure.

  Therefore, an object of the present invention is to provide a ventilation structure that is excellent in ventilation performance and rain performance, and a building equipped with this ventilation structure.

  In order to achieve the above object, the ventilation structure of the present invention is provided with an outer casing protruding outward along the longitudinal direction of the eaves of the building, and the ventilation space of the building and the outside thereof are provided. A ventilation port formed at the eaves of the building to be communicated is configured to be positioned above the outer fence.

  Here, the outer surface of the ventilation opening may be formed of a draining material extending from an end of the roof of the building.

  Moreover, the inlet of the said ventilation port is good to be set so that it may be located below rather than the outer upper edge part of the said outer casing.

  Furthermore, it is preferable that a water return portion that protrudes from the inside of the building toward the outside of the building with a length that secures a ventilation path is provided in the ventilation port.

  Moreover, it is good to provide the bird-proof and waterproof board part in which the slit hole extended in the longitudinal direction of the eaves part was formed in the entrance vicinity in the said ventilation opening.

  The building of the present invention includes the above-described ventilation structure.

  Here, the building has a one-sided roof, and the ventilation space is a one-sided attic space formed on the lower side of the roof, and the ventilation port is provided at the eaves under the roof. Is formed as a ventilation opening for supplying air, and an exhaust ventilation opening communicating with the attic space is preferably formed in the eaves portion on the water side of the roof.

  Such a ventilation structure of the present invention is provided with an outer casing projecting outward along the longitudinal direction of the eaves portion of the building, and at the eaves of the building communicating the ventilation space of the building and the outside thereof. The formed ventilation port is configured to be positioned above the outer casing.

  With such a configuration, since the intrusion of wind and rain from the lower side of the ventilation port is suppressed by the lower surface of the outer casing, the ventilation performance is excellent and the rain performance is also excellent.

  Here, when the outer surface of the ventilation port is formed of a drainer extending from the end of the roof of the building, such a ventilation port can be easily formed.

  In addition, when the entrance of the ventilation port is set to be positioned below the outer upper edge of the outer casing, the intrusion of wind and rain by the outer surface of the outer casing wraps around from the side of the vent Therefore, the rain performance can be further improved.

  In addition, if there is a water return section in the ventilation opening that protrudes from the inside of the building to the outside of the building with a length that secures the ventilation path, rainwater will rise from the ventilation opening by any chance. Since it can be eliminated even if it comes, it can be made more excellent in rain performance.

  In addition, if there is a bird / waterproof board with slits extending in the longitudinal direction of the eaves near the entrance in the ventilation opening, birds, etc. invade through this bird's / waterproof board In addition to being able to prevent nesting and nest formation, the rain performance can be further improved.

  Such a building of the present invention is configured to have the above-described ventilation structure.

  With such a configuration, it is possible to construct a building that exhibits the effects described above.

  Here, the building has a one-sided roof, and the ventilation space is a one-sided attic space formed on the lower side of the roof. If the vents on the upper water side of the roof are ventilated for exhaust and communicate with the attic space, the inside of the attic space is warmer than the outside of the building. The ventilation air supplied from the ventilation vent is exhausted from the ventilation vent for the updraft in the attic space, so that efficient ventilation can be performed.

It is explanatory drawing which shows schematic structure of the building provided with the ventilation structure of Example 1. FIG. FIG. 2 is an enlarged cross-sectional view taken along line AA in FIG. 1, and is an explanatory diagram illustrating a schematic configuration of a ventilation structure according to the first embodiment.

  Hereinafter, the form for implementing this invention is demonstrated based on Example 1, 2 shown to drawing.

  First, the configuration of the first embodiment will be described.

  FIG. 1 shows a schematic configuration of a building 1 having a ventilation structure of the first embodiment.

  As shown in FIG. 1, this building 1 has a roof Y that is slanted.

  The main part of the ventilation structure of the first embodiment is configured on the underwater side of the one-side inclined roof Y as shown in FIG.

  In this building 1, as shown in FIG. 2, it protrudes outward of the building 1 through a crosspiece 4 along the longitudinal direction of the web portion of the eaves beam 3 of the grooved steel constituting the eaves portion N. The outer casing 5 is provided.

  In addition, a vertical gutter with a lower portion (not shown) connected to the sewer is provided on the water side (front side of the paper) of the outer gutter 5 so that rainwater collected in the outer gutter 5 can be drained. Yes.

  Further, between the crosspiece 4 and the outer fence 5, a cross section having a water return portion 61 facing outward of the building 1 in the upper portion and a water return portion 62 facing inward of the building 1 in the lower portion. A substantially Z-shaped water return member 6 is sandwiched and provided.

  Further, the eaves beam 3 is supported by a grooved steel roof beam 8 via a waterproof packing 7 between the flange portions.

  A waterproof sheet 19 is attached between the upper flange portion of the roof beam 8 and the upper end portion of the outer wall 9.

  Furthermore, the lower surface of the base plate 10 constituting the one-sided roof Y is supported by rafters 11.

  Here, a support member 13 having a substantially V-shaped cross section is provided between the rising portion of the rafter receiving member 12 having a substantially L-shaped cross section that receives the lowermost rafter 11 and the upper flange portion of the eaves beam 3. Yes.

  A plurality of the support members 13 are provided at predetermined intervals along the longitudinal direction of the eaves beam 3 so that a large load of the roof Y can be transmitted to the eaves beam 3 and also a ventilation path can be secured. Yes.

  Further, a roof material 14 is laid on the top surface of the field board 10 to constitute a roof Y that is inclined one side.

  A hook portion 14 a is formed at the lower end portion of the roof material 14, and the hook portion 15 a is engaged with the hook portion 14 a and a clip member 15 is provided.

  The draining material 16 extends from the eaves of the roof Y by sandwiching and fixing the upper end portion of the draining material 16 between the clip member 15 and the lower end portion of the field board 10.

  The lower end portion 16 a of the draining material 16 is slightly lower than the outer upper edge portion of the outer rod 5 from the upper central portion of the outer rod 5 with a space from the tip of the water returning portion 61 of the water returning member 6. It hangs down until it is located.

  Thereby, the ventilation opening E of the ventilation structure of this Example 1 is formed.

  Here, in the vicinity of the entrance of the ventilation opening E, a birdproof / waterproof board 17 having a plurality of slit holes extending in the longitudinal direction of the eaves N is provided.

  And as shown by the arrow W, the air supplied from the ventilation port E enters the attic space 2 as the ventilation space, ventilates the inside of the attic space 2, and then enters the eaves portion on the water side of the roof Y. It exhausts from the formed ventilation opening which abbreviate | omitted illustration.

  Next, the effect of Example 1 is demonstrated.

  Such a ventilation structure of Example 1 is provided with an outer fence 5 protruding outward along the longitudinal direction of the eaves portion N of the building 1, and an attic space 2 as a ventilation space of the building 1 and A ventilation port E formed at the eaves of the building 1 that communicates with the outside is configured to be located above the outer cage 5.

  Since it is such a structure, since the infiltration of the wind and rain from the downward direction of the ventilation port E is suppressed by the lower surface of the outer casing 5, it is excellent in ventilation performance and rain performance.

  Here, the outer surface of the ventilation port E is formed of a draining material 16 extending from the end of the roof Y of the building 1.

  For this reason, such a ventilation port E can be formed easily.

  Further, the inlet of the ventilation port E is set to be positioned below the outer upper edge of the outer casing 5.

  For this reason, since the outer surface of the outer casing 5 suppresses the intrusion of wind and rain from the lateral direction of the ventilation opening E, the rain performance can be further improved.

  Furthermore, in the ventilation opening E, the water return part 61 which protrudes toward the outer side of the building 1 from the inner side of the building 1 with the length which ensures a ventilation path | route is provided.

  For this reason, since this water return part 61 can be removed even if rainwater comes up from the ventilation port E, it can be made more excellent in rain performance.

  Further, in the vicinity of the entrance in the ventilation opening E, there is provided a birdproof / waterproof board portion 17 in which a slit hole extending in the longitudinal direction of the eaves portion N is formed.

  For this reason, the bird-proof / waterproof board portion 17 can prevent the entry of birds and the like and make nests, and can further improve the rain performance.

  Such a building 1 according to the first embodiment is configured to include the ventilation structure according to the first embodiment.

  Since it is such a structure, the building which show | plays the effect of the ventilation structure of Example 1 mentioned above can be constructed | assembled.

  Here, the building 1 has a one-sided roof Y, and the ventilation space is a one-sided attic space 2 formed on the lower side of the roof Y. Is formed as an air supply ventilation opening, and an exhaust ventilation opening (not shown) communicating with the attic space 2 is formed in the eaves part on the water side of the roof Y.

  For this reason, since the inside of the attic space 2 is warmer than the outside of the building 1, the ventilation air supplied from the ventilation vent E for supply of air is not shown on the updraft in the attic space 2. It is exhausted from the vent for exhaust, and efficient ventilation can be performed.

  Next, Example 2 will be described.

  In addition, the description which attaches | subjects the same code | symbol about the description of the same thru | or equivalent part as the content demonstrated in Example 1, and demonstrates.

  FIG. 3 shows a schematic configuration of the ventilation structure of the second embodiment.

  In the ventilation structure of the second embodiment, a plurality of slit holes extending in the longitudinal direction of the eaves portion N at the rising portion are formed between the lower end portion of the field plate 10 and the water return member 6. The waterproof member 18 is mainly different from the ventilation structure of the first embodiment.

  For this reason, since the waterproof member 18 is provided, the rain performance can be further improved.

  Other configurations and functions and effects are substantially the same as those in the first embodiment, and thus description thereof is omitted.
