Description

The present invention relates to buildings.

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

The vent allows ventilation in the upper and lower parts of the roof, and the cover prevents rainwater and the like from entering through the vent. The parting wall also extends from the floor to the underside of the roof.

If a fire breaks out in one room of the building described in Patent Document 1, flames and sparks may reach the underside of the roof and spout or scatter outside through the vents and the cover.

Here, in Patent Document 2, in a building having vents (openings) formed along the ridges of the roof, when a fire breaks out inside the building, air containing sparks is not discharged to the outside. To prevent this, it is disclosed to place a fire damper in the vent. The fire damper includes a thermal expansion member that expands upon sensing heat to cover the vent on the roof.

If the fire damper described in Patent Document 2 is placed in the vent of the building described in Patent Document 1, flames and sparks generated in one room of the building will be ejected or scattered outdoors through the vent and the cover. less likely to

The fire damper described in Patent Document 2 is arranged above the ridge of the roof. Therefore, in the building described in Patent Document 2, even if a fire damper is placed on the parting wall, flames and sparks generated in one room may erupt or scatter into the next room through the gap between the fire damper and the parting wall, The fire may spread inside the object.

The present invention has been made in view of such problems, and it is possible to suppress the ejection or scattering of flames and sparks generated in one room to the next room while allowing ventilation above and below the roof. The purpose is to provide a building.

As a result of various studies, the inventors of the present invention have found that the above objects are achieved by the following inventions.

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. a vent covering portion covering the vent from above in a region overlapping the wall member with a vertical gap formed between the wall member and the roof member; and the wall member and the vent covering. and at least one barrier provided in a range from the upper surface of the wall member to the lower surface of the vent covering portion through the vent in the region overlapping the wall member from above.

In addition to the vent cover and the wall member, the above-described building includes a barrier provided in a range from the top surface of the wall member to the bottom surface of the vent cover. Therefore, two adjacent rooms partitioned by the wall member are independently ventilated through the vents up to the vent covering portion and the lower surface of the roof member. In addition, flames and sparks caused by a fire in one room are prevented from spouting or scattering to other rooms by the barrier.

Therefore, it is possible to suppress the ejection or scattering of flames or sparks generated in one room to the adjacent room while allowing ventilation in the upper and lower parts of the roof.

The building has two barriers, and the wall member has two wall plates facing each other with a gap in the direction along the ridge, and the wall plates overlap from above. Each barrier may be provided in the region.

In this manner, the barrier can be made lighter and simpler than 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 the upper surface of the roof member to the lower surface of the vent covering portion, and a lower barrier portion extending from the upper barrier portion to the wall member through the vent. may have.

In this aspect, the barrier can be provided by providing the building with a roof member having a vent, then providing a lower barrier portion extending to the wall member through the vent, and providing an upper barrier portion on the upper side of the roof member. can. Therefore, the barrier can be provided relatively easily.

The above building comprises a lower member and an upper member for constituting the upper barrier section, and a tile provided at the edge of the vent in the roof member, the lower member being the roof The upper member includes a first barrier portion attached to a member and extending upwardly from the top surface of the roof member, the upper member including the vent covering portion and the vent covering portion extending laterally from the vent covering portion. a tile covering portion that covers a part of the tile from above; a regulation portion that is provided between the tile and the tile covering portion and regulates the flow of water between the upper surface of the tile and the tile covering portion; and a second barrier portion extending from the vent cover portion to a position horizontally overlapping with the first barrier portion.

Here, generally, the position of the roof tile with respect to the roof member often varies from building to building. Also, the dimensions of the upper barrier portion vary depending on the position of the tile with respect to the roof member. Therefore, when the upper barrier part is to be integrated, it is necessary to fabricate the upper barrier part having dimensions corresponding to the positions of the roof member and roof tiles after the positions of the roof members and roof tiles are determined at the work site. However, in this aspect, the first barrier section and the second barrier section have an overlapping portion, and the size of this overlapping 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 section and the second barrier section having dimensions corresponding to the positions of the roof member and roof tile at the work site.

Furthermore, in this aspect, the restricting portion provided on the upper member can prevent water such as rainwater from traveling along the upper surface of the roof tile toward the vent.

The above-mentioned building comprises a fixed portion attached to the edge of the vent in the roof member on both sides of the upper member and the lower member in the direction in which the ridge extends; a sandwiching member that extends to the roof member and sandwiches the tile between itself and the roof member; a covering member that extends along the ridge and covers the sandwiching member from above and from the sides of the ridge; and the upper member and the lower member may be covered from above and laterally of the ridge by the covering member.

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

In the above structure, the lower member includes an attachment portion attached to the edge of the vent in the roof member, and an attachment portion that rises from the attachment portion and extends along the edge and to the first barrier portion. and a connected riser.

In this aspect, even if water enters between the roof member and the roof tile, the rising portion can prevent the water from entering the vent.

According to the present invention, it is possible to suppress the movement of flames and sparks from one room to the next while maintaining ventilation through the vents in each adjacent room with a barrier of relatively simple construction. Buildings can be provided.

At this time, the rooms on both sides of the partition wall 4 are kept independently ventilated through the air vents 5. - 特許庁

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

For example, when rainwater flows along the upper surface of the roof tile 16 toward the ventilation port 5 with the wind, the rainwater is drained by the ridge drainer 21 or the tile covering portion 37 and the roof tile 16 by the regulating portion 21c and the regulating portion 39. It is suppressed to infiltrate between Even if rainwater enters between the ridge drainer 21 or the tile covering portion 37 and the roof tile 16, the rainwater is prevented from reaching the vent 5 by the base plate 13d and the watertight material 13e. Rainwater running on the lower part 21b of the ridge drainer 21 or the tile covering part 37 of the upper member 35 is guided away from the vent 5 by the upper part 21a or the vent covering part 36. - 特許庁

The asphalt roofing 14 suppresses rainwater falling from the gaps of the roof tiles 16 toward the sheathing board 11 from penetrating into the sheathing board 11. - 特許庁When rainwater falling on the asphalt roofing 14 flows in the direction of the vent 5 due to the wind, the roof tile 15, the rising portion 12b of the splint 12 and the base 32 suppress the rainwater from entering the vent 5.

In the building 1 of this embodiment, barriers 6 are provided on each of the wall plates 4a and 4b of the partition wall 4. As shown in FIG. Therefore, the barrier 6 can be provided with a light weight and simple structure compared to the case of providing 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.

In addition, in the building 1 of the present embodiment, the barrier 6 has a lower barrier section 8 and a first barrier section 34 and a second barrier section 38 that constitute an upper barrier section. Therefore, after providing the sheathing board 11 having the ventilation openings 5, the lower barrier section 8 is provided, and then the ventilation opening 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 section 8 and the upper barrier section are integrated.

Further, in the building 1 of this embodiment, the vent covering unit 7 is composed of the lower member 31 and the upper member 35 . Here, in general, the position of roof tile 16 with respect to sheathing board 11 often varies for each building 1 . Therefore, when the lower member 31 and the upper member 35 constituting the vent covering unit 7 are integrally provided, after the positions of the sheathing board 11 and roof tile 16 are determined at the work site, It is necessary to make a dimensioned vent covering unit 7 .
