Description

  The present invention relates to buildings.

  For example, as disclosed in Patent Literature 1, a gable roof having a vent formed along a ridge, a cover provided above the vent, and two adjacent rooms along the ridge are partitioned. BACKGROUND ART A building having a boundary wall is conventionally known.

  The vents allow ventilation above and below the roof, and the cover suppresses intrusion of rainwater or the like from the vents. The boundary wall extends from the floor to the lower surface of the roof.

  When a fire occurs in one room of the building described in Patent Literature 1, there is a possibility that flame or sparks may reach the lower surface of the roof and squirt or scatter outside through a vent and a cover.

  Here, in Patent Literature 2, in a building having a vent (opening) formed along the roof ridge, if a fire occurs inside the building, air including sparks is not discharged to the outside. In order to achieve this, it is disclosed that a fireproof damper is disposed at the vent. The fire protection damper includes a thermal expansion member. When heat is sensed, the thermal expansion member expands and covers the vent on the roof.

  If the fire damper described in Patent Literature 2 is arranged in the ventilation opening of the building described in Patent Literature 1, the flame or sparks generated in one room of the building squirt or scatter outside through the ventilation hole and the cover. The likelihood of doing so is reduced.

JP 2003-213832 A JP 2003-328470 A

  The fire protection damper described in Patent Literature 2 is disposed above a roof ridge. Therefore, in the building described in Patent Literature 2, even if a fire damper is arranged on the boundary wall, the flame or sparks generated in one room squirt or scatter into the adjacent room through the space between the fire prevention damper and the boundary wall. There is a risk that the fire will spread in the object.

  The present invention has been made in view of such a problem, and it is possible to suppress blowout or scattering of a flame or sparks generated in one room to an adjacent room while allowing ventilation above and below the roof. The purpose is to provide buildings.

  As a result of various studies, the present inventors have found that the above object is achieved by the following invention.

  A building according to one aspect of the present invention includes a roof member having a vent formed along a ridge, and a wall member extending downward from the roof member and formed along a direction intersecting the vent. And a vent covering portion covering the vent from above in a region overlapping from above with the wall member in a state where a vertical gap is formed between the roof member and the roof member. At least one barrier provided in a range from the upper surface of the wall member to the lower surface of the ventilation port covering portion through the ventilation hole in a region overlapping the wall member from above between the wall member and the wall member.

  The building includes a barrier provided in a range from an upper surface of the wall member to a lower surface of the vent cover in addition to the vent cover and the wall member. Therefore, in the two adjacent rooms partitioned by the wall member, the ventilation through the vent is independently maintained up to the vent cover and the lower surface of the roof member. In addition, fire or sparks resulting from a fire generated in one room are prevented from spouting or scattering into another room by the barrier.

  Therefore, it is possible to suppress the emission or scatter of the flame or sparks generated in one room into the adjacent room while allowing the ventilation above and below the roof.

  The building has two barriers, and the wall member has two wall plates facing each other at intervals in a direction along the ridge, and overlaps each of the wall plates. Each of the barriers may be provided in a region.

  In this aspect, the barrier can be made lighter and simpler in configuration than when using a barrier having the same thickness as the entire wall member, including the two wall plates and the space between them.

  In the above building, the barrier includes an upper barrier portion extending from an upper surface of the roof member to a lower surface of the vent cover portion, and a lower barrier portion extending from the upper barrier portion to the wall member through the vent hole. You may have.

Therefore, the barrier can be provided relatively easily.

  The building includes a lower member and an upper member for constituting the upper barrier portion, and a tile provided at an edge of the ventilation port in the roof member, wherein the lower member includes the roof. A first barrier portion attached to the member and extending upward from an upper surface of the roof member, wherein the upper member includes the vent cover portion, and the side member extending laterally from the vent cover portion; A tile covering portion that covers a part of the tile from above, a regulating portion that is provided between the tile and the tile covering portion and regulates a flow of water between an upper surface of the tile and the tile covering portion, A second barrier portion extending from the ventilation port covering portion to a position overlapping the first barrier portion in the horizontal direction may be provided.

  Here, in general, the position of the tile with respect to the roof member often varies from building to building. The size of the upper barrier portion varies depending on the position of the tile with respect to the roof member. Therefore, in the case where the upper barrier portion is integrated, after the positions of the roof member and the tile are determined at the work site, it is necessary to produce an upper barrier portion having a size corresponding to these positions. However, in this aspect, the first barrier portion and the second barrier portion have a portion that overlaps, and the size of the overlap portion varies according to the position of the tile with respect to the roof member provided in the building. . Therefore, it is not necessary to manufacture the first barrier portion and the second barrier portion having dimensions corresponding to the positions of the roof member and the tile at the work site.

  Further, in this aspect, the regulating portion provided on the upper member can prevent water such as rainwater from traveling on the upper surface of the tile toward the ventilation hole.

  The above-mentioned building includes a fixing portion attached to an edge of the ventilation hole in the roof member on both sides of the upper member and the lower member in a direction in which the ridge extends, and A holding member that extends to the roof member and holds the tile between the roof member and a covering member that extends along the ridge and covers the holding member from above and from the side of the ridge. The upper member and the lower member may be covered by the covering member from above and from the side of the ridge.

  In this aspect, both the portion above the wall member of the vent and the portion other than above the wall member can be covered by the common covering member.

  In the above building, the lower member is attached to an edge of the ventilation port of the roof member, and rises from the attachment, extends along the edge, and extends along the first barrier. And a rising portion to be connected.

  In this aspect, even if water invades between the roof member and the tile, it is possible to suppress the intrusion of the water into the ventilation hole by the rising portion.

  Advantageous Effects of Invention According to the present invention, it is possible to suppress the movement of flames and sparks from one room to the next room while maintaining ventilation through the vents in each adjacent room by the barrier having a relatively simple configuration. A building can be provided.

The regulating portion 39 is attached to the lower surface of the tile covering portion 37 and is pressed against the upper surface of the tile 16 by the tile covering portion 37. Thus, the regulating portion 39 regulates the flow of water between the upper surface of the tile 16 and the tile covering portion 37. For example, rainwater on the upper surface of the tile 16 passes under the tile covering portion 37 due to wind and the ventilation hole Suppress circulation to the 5 side. The regulating section 39 can use, for example, ethylene propylene rubber. Further, a metal plate such as a galvalume steel plate (registered trademark) can be used for a portion other than the regulating portion 39 of the upper member 35.

  The cross-sectional size of the ventilation port covering portion 36 and the tile covering portion 37 by a plane perpendicular to the X direction is equal to or smaller than the cross-sectional shape of the trash dump 21 by a surface perpendicular to the X direction. For this reason, in the building 1 according to the present embodiment, the ridge parcel 24 covers the ridge dumping drain 21 and the sandwiching member 13 from both sides in the + Z direction and the Y direction, similarly to the upper member 35 and the lower member 31.

The mechanism that is performed will be described.

  With reference to FIGS. 3 to 6, a case where a fire occurs in one room partitioned by the boundary wall 4 will be considered. In the building 1 of the present embodiment, when any one of the lower member 31, the upper member 35, and the lower barrier portion 8 is missing, the flame or the like that has risen along the boundary wall 4 with the ascending airflow is: Through the ventilation hole 5 or the space between the base plate 11 and the ridge cover 24, the air blows and scatters toward an adjacent room sandwiching the boundary wall 4.

  On the other hand, when the lower member 31, the upper member 35, and the lower barrier portion 8 are aligned, the flame or the like rises along the boundary wall 4 with the ascending airflow, and then the lower barrier 31 After rising along the portion 8 and further along the first barrier portion 34 and the second barrier portion 38, the vent cover portion 36, the rising portion 33 of the lower member 31, and the rising portion of the attachment plate 12. It is guided in the + X direction by 12b. Therefore, the movement of the flame or the like to the adjacent room sandwiching the boundary wall 4 is suppressed. At this time, in the rooms on both sides of the boundary wall 4, the ventilation through the ventilation holes 5 is maintained independently.

  Further, in the building 1 of the present embodiment, a mechanism for suppressing the rainwater falling on the roof 2 from flowing into the vent 5 will be described.

  For example, when rainwater flows along the top surface of the roof tile 16 toward the ventilation hole 5 with the wind, the rainwater is discharged by the regulation part 21c and the regulation part 39 with the draining drain 21 or the tile covering part 37 and the roof tile 16. Is suppressed from entering the space. Even if rainwater enters between the drainage drain 21 or the tile covering portion 37 and the tile 16, the base plate 13d and the watertight material 13e suppress the rainwater from reaching the vent 5. The rainwater that has run on the lower part 21 b of the ridge dumper 21 or the tile covering part 37 of the upper member 35 is guided in a direction away from the vent 5 by the upper part 21 a or the vent covering part 36.

  Rainwater that has fallen in the direction of the base plate 11 from the gap between the roof tiles 16 is prevented from penetrating into the base plate 11 by the asphalt roofing 14. When rainwater that has fallen on the asphalt roofing 14 flows in the direction of the ventilation port 5 due to the wind, the infiltration of rainwater into the ventilation port 5 is suppressed by the tile bar 15, the rising portion 12 b of the attachment plate 12, and the base 32.

  In the building 1 of the present embodiment, a barrier 6 is provided on each of the wall plates 4a and 4b of the boundary wall 4. For this reason, the barrier 6 can be provided with a lighter weight and a simple configuration as compared with the case where the barrier 6 having a thickness covering the entire thickness of the boundary wall 4 including the space between the wall plates 4a and 4b is provided.

  Further, in the building 1 of the present embodiment, the barrier 6 has the lower barrier portion 8 and the first barrier portion 34 and the second barrier portion 38 constituting the upper barrier portion. Therefore, after providing the base plate 11 having the ventilation port 5, the lower barrier section 8 is provided, and then the ventilation port covering unit 7 having the first barrier section 34 and the second barrier section 38 is provided. 6 can be provided. Therefore, the barrier 6 can be provided more easily than when the lower barrier 8 and the upper barrier are integrated.

  In the building 1 of the present embodiment, the ventilation port covering unit 7 is further configured by the lower member 31 and the upper member 35. Here, in general, the position of the roof tiles 16 with respect to the ground board 11 often varies for each building 1. Therefore, when the lower member 31 and the upper member 35 that constitute the ventilation hole covering unit 7 are provided integrally, after the positions of the base plate 11 and the roof tile 16 are determined at the work site, the positions corresponding to these positions are determined. It is necessary to manufacture a vent cover unit 7 having dimensions. However, in the building 1 of the present embodiment, the first barrier portion 34 of the lower member 31 and the second barrier portion 38 of the upper member 35 have a portion overlapping in the X direction, and the size of the overlapping portion Fluctuates according to the position of the roof tiles 16 with respect to the ground board 11 provided in the building 1. Therefore, in the building 1 according to the present embodiment, the sizes of the first barrier portion 34 and the second barrier portion 38 are adjusted to a size corresponding to the position of the roof tile 16 with respect to the field board 11 provided at the work site. There is no need to use the lower member 31 and the upper member 35 prepared in advance as they are.

(Modification of this embodiment)
The boundary wall 4 may be made of one gypsum board. In this case, the barrier 6 may be provided at one position.

  The upper member 35 and the lower member 31 may be formed integrally. Further, in addition to the upper member 35 and the lower member 31, the lower barrier portion 8 may be formed integrally.
