Description

  The present invention relates to a ventilation building in which a gap is provided between field boards, and ventilation is performed through the gap.

  There is a known ventilation building that allows ventilation through the building. As a ventilation building, for example, a structure in which left and right field boards are provided with a gap at the top, a purlin is attached above the gap between the field boards, a crown tile is attached to the top of the tower, and a lower part of the crown tile is opened. is there.

  Furthermore, various structures are known as a ventilation building so that rainwater does not enter the building through the gap between the field plates. As an example, a structure in which a breathable water shielding plate (hereinafter referred to as “water shielding plate”) is provided between a crown tile and a purlin is known. This water shielding plate is made of a light metal thin plate such as an aluminum plate, and is installed between the purlin and the roof tile, ensuring ventilation in the building and setting the ventilation holes appropriately. It is a member that prevents rainwater from entering.

JP 2008-208618 A

  However, when the said water shielding board receives the maximum wind speed assumed, it will generate | occur | produce that rain water will permeate the inside of a building by passing rain water through the vent hole of a water shielding board. Therefore, it is considered to provide a breathable waterproof cloth or the like between the purlin and the water shielding board to block rainwater that has passed through the water shielding board and entered the building with the waterproof cloth.

  On the other hand, since the lower part of the water shielding plate is attached to the top surface of the roof tile with an adhesive or the like, it is considered that rain water collects between the water shielding plate and the waterproof cloth when the rain water is blocked by the waterproof cloth. . If rainwater accumulates between the water shielding plate and the waterproof cloth, the ridge will be constantly moistened, causing dirt, or the adhesive that has attached the water shielding plate to the roof tile will be altered, causing the water shielding plate to It may be peeled off from the roof tile.

  Further, the height from the roof tile to the purlin and the width of the gap formed between the field boards differ from building to building, and the mode is not uniform. Then, the space between the water shielding plate and the purlin is narrowed, and sufficient air permeability may not be obtained.

  The present invention solves the above-mentioned problems, and in a ventilation building using a breathable water-impervious member provided with a vent hole for ventilation, the cost is low, the air permeability and the waterproof performance are ensured with a simple configuration, and the air-shielding member is shielded. The purpose is to provide a ventilation building where rainwater does not collect at the bottom of the water plate.

In order to solve the above-described problems, the ventilation wing is configured as follows in the present invention.
Two field plates are abutted with a predetermined gap. Purlins are provided along the gap. Spread tiles on the field board. The crown tile is provided on the purlin with a ventilation space between it and the tile.

  A water shielding plate is provided so as to partition the ventilation space and the gap. The water shielding plate is provided with a vent hole penetrating in the front and back direction. Furthermore, a sticking part is provided in the part below the vent hole of the water shielding plate. The affixing portion is formed such that the corrugations of the cross-sectional waveform are continuously formed along the inclination direction. The affixing part is attached on the roof tile without closing the continuous space formed by the irregularities on the way.

  A waterproof member having air permeability is provided inside the water shielding plate. The waterproof member is attached from the purlin to the pasting part. The waterproof member covers at least a portion where the ventilation hole is formed, and the lower end thereof is placed on the roof tile. Furthermore, the lower part of the waterproof member and the water-impervious member communicate with a continuous space formed between the sticking portion and the roof tile. The lower part of the waterproof member is not only placed on the roof tile, but may be attached to the roof tile or the lower surface of the pasting portion.

  As an example, the waterproof member is formed of an upper mounting plate, a ventilation member made of corrugated plate, and the like, and a lower waterproof cloth. The ventilation member has a predetermined thickness and allows ventilation along a line connecting the upper mounting plate and the lower waterproof cloth. The upper mounting plate is provided on the upper surface of the ventilation member in the plate thickness direction, and the lower waterproof cloth is provided on the lower surface of the ventilation member.

  Further, the upper mounting plate is made of, for example, a resin plate and has a fold line formed in the lateral direction, and is divided into an upper half and a lower half with the fold line as a boundary. The broken line allows the upper half and the lower half to be bent up and down. The upper half is attached to the side of the purlin with an adhesive or the like. The lower half is attached so as to overlap with the upper part of the ventilation member, for example, the top portion of the corrugated plate (ventilation member) by a predetermined length.

  For example, the lower waterproof cloth is attached to the curved lower bottom portion of the corrugated plate so as to overlap each other by a predetermined length. The lower waterproof cloth has a length sufficient to come into contact with the roof tile when the waterproof member is attached to the purlin.

  Moreover, as another example of the ventilation wing, a waterproof thin piece having air permeability was provided between the water shielding member and the purlin. The waterproof flake is a member made of cloth, non-woven fabric, waterproof paper or the like that allows air to pass in the front and back directions but does not allow water to pass. The breathable waterproof flakes are kept in contact with the bottom of the roof tile as described above.

  The ventilation building according to the present invention has the following effects.

  The room air that has flowed out from the gap between the field boards is discharged out of the building from the open space of the roof tile through the waterproof member and the vent hole formed in the water shielding member. Thereby, ventilation in a building is implemented. Further, the ventilation member has a space extending in the thickness direction, and sufficient ventilation is performed.

  On the other hand, rainwater is blocked by the water shielding member, wind speed increases, and even if rainwater passes through the vent hole of the water shielding member, it is blocked by the waterproof member, and rainwater can be reliably prevented from entering the building. The

  More specifically, rainwater that hits the upper mounting plate of the waterproof member flows on the upper mounting plate and falls on the corrugated plate. Rainwater further travels from the corrugated sheet to the lower waterproof cloth and flows downward. And when rainwater reaches the lower part of the lower waterproof cloth, it passes through the spaces formed between the uneven part of the sticking part of the water shielding member and the lower waterproof cloth and between the uneven part of the sticking part and the adhesive material, respectively. To flow onto the roof tile. As a result, rainwater does not enter the building from the ventilation building, and the rainwater flows out onto the roof tile, and the rainwater does not accumulate inside the water shielding member.

Moreover, the sticking part 36 is provided with a softness | flexibility, and can expand the groove | channel 40 suitably and can make it follow arbitrary shapes.

  As shown in FIG. 3, the inclined plate 18 is formed of an upper mounting plate 42, a corrugated plate 44 as a ventilation member, and a lower waterproof cloth 46. The upper mounting plate 42 is provided with a fold line 48 in the lateral direction substantially at the center, and is divided into an upper half 50 above the fold line 48 and a lower half 52 below the fold line 48. Due to the fold line 48, the upper half 50 and the lower half 52 can be bent in the vertical direction. The upper half 50 is bonded to the side surface of the purlin 14 with an adhesive or the like.

  The lower half 52 is fixed to the top of the corrugated plate 44 having a corrugated shape. The corrugated plate 44 is a corrugated plate made of synthetic resin or the like, and the lower half 52 and the corrugated plate 44 are attached to overlap each other by a predetermined length. Further, the lower half 52 and the corrugated plate 44 have no gap between the lower end of the lower half 52 and the upper end of the corrugated plate 44 when viewed from the horizontal direction with the inclined plate 18 attached to the purlin 14. It is preferred that at least both overlap to the extent.

  A lower waterproof cloth 46 is attached to the lower part of the corrugated plate 44. The lower waterproof cloth 46 is fixed to the bottom of the corrugated plate 44 having a wave-curved shape. The lower waterproof cloth 46 and the corrugated sheet 44 are attached so as to overlap each other by a predetermined length, and the lower end of the corrugated sheet 44 and the lower waterproof cloth are viewed from the horizontal direction with the inclined plate 18 attached to the purlin 14.

  Further, as shown in FIG. 4, the lower waterproof cloth 46 is affixed to the affixing portion 36 so as not to overlap the adhesive 64 that attaches the water shielding plate 16 to the roof tile 22. The lower waterproof cloth 46 has a water shielding plate 16 such that a space formed between the lower waterproof cloth 46 and the groove 40 is continuous with a space formed between the adhesive 64 and the groove 40. It only has to be pasted on.

  Next, the operation and effect of the ventilation building 10 will be described.

  In the ventilation building 10, warm air in the building (referred to as “room air”) flows into the inside of the crown tile 12 through the gap A provided between the field boards 20 as indicated by the dotted arrows in FIG. 1. To do. The room air that has flowed into the inside of the crown tile 12 further passes between the corrugated plate 44 and the upper mounting plate 42 or between the corrugated plate 44 and the lower waterproof cloth 46 and flows out of the inclined plate 18. The room air that has flowed out of the inclined plate 18 passes through the ventilation hole 38 of the water shielding plate 16, passes through the ventilation space 3 between the crown tile 12 and the roof tile 22, and is discharged to the outside of the building.

  Rainwater may enter the inside of the roof tile 12 through the ventilation space 3 together with the wind. Rainwater that enters the inside of the roof tile 12 is blocked by the water shielding plate 16, and rainwater does not enter the building any more during normal rainfall. And when a wind speed becomes more than predetermined, rain water may pass through the vent hole 38 of the water shielding board 16. Then, rainwater hits the inclined plate 18 and rainwater flows down along the inclined plate 18.

  Regardless of whether it hits the upper mounting plate 42, the corrugated plate 44, or the lower waterproof cloth 46, the rainwater hitting the inclined plate 18 flows down sequentially from the respective locations to form the groove 40 of the water shielding plate 16. It passes between the lower waterproof cloths 46 and reaches the lower part of the back surface of the water shielding plate 16. Then, since a space is formed between the groove 40 of the water shielding plate 16 and the adhesive 64 at the bottom of the back surface of the water shielding plate 16, the rainwater further flows out to the upper surface of the roof tile 22 through the space. .

  The inclined plate 18 is inclined at a predetermined angle, and the wind speed is reduced by the ventilation hole 38. Therefore, even when the wind speed is high, the inclined surface of the inclined plate 18 rises and rainwater flows into the inclined plate 18. Does not occur.

  Therefore, according to the ventilation building 10, the corrugated plate 44 ensures a sufficient ventilation path and exhibits a reliable ventilation function, and the water shielding plate 16 and the inclined plate 18 reliably prevent the intrusion of rainwater, Good waterproof performance can be brought about. Moreover, the water shielding plate 16 can be easily formed by pressing a thin aluminum plate, and the inclined plate 18 can be formed of a corrugated plate 44 made of synthetic resin. Is possible.

  Furthermore, the ventilation building 10 can be applied to ventilation buildings of various buildings by appropriately selecting the length of the corrugated plate 44 of the inclined plate 18, the length of the lower waterproof cloth 46, or the eaves 62. Moreover, even if the water shielding plate 16 and the purlin 14 are close to each other and the distance is small, the corrugated plate 44 is used, so that a sufficiently wide ventilation passage is secured to ensure ventilation in the building. Can be done.

  Next, another example of the inclined plate is shown in FIG. The inclined plate 19 is formed by using a ventilation member 70 having a partition wall 68 inside as shown in the drawing instead of the corrugated plate 44 of the inclined plate 18. Even when such a ventilation member 70 is used, the inclined plate 19 can obtain the same effects as those obtained when the corrugated plate 44 is used.

  Next, another example of the ventilation building will be described. As shown in FIG. 7, the ventilation building 11 includes a nonwoven fabric 72 as a breathable waterproof thin piece instead of the inclined plate 18 of the ventilation building 10. The nonwoven fabric 72 has air permeability and waterproof performance. The non-woven fabric 72 covers the upper part of the purlin 14 like the water shielding plate 16 and is attached to the back surface of the water shielding plate 16 on both lower sides. Furthermore, the lower end of the nonwoven fabric 72 is pasted so that the space formed between the groove 40 (see FIG. 4) and the nonwoven fabric 72 is continuous with the space formed between the groove 40 and the adhesive 64. ing.

According to the ventilation building 11, the building can be ventilated through the gap A and can be waterproofed by the water shielding plate 16. Further, even when rainwater passes through the water shielding plate 16, the intrusion of rainwater is blocked by the nonwoven fabric 72. Can be reliably waterproofed. Further, rainwater that has passed through the water shielding plate 16 flows out to the upper surface of the roof tile 22 through the space formed by the groove 40. Such a ventilation building 11 can realize sufficient ventilation and reliable waterproofing with a simple configuration.
Although the above example has been described in the main building, the present invention is not limited to this.

  The present invention can be used in a ventilation building of a building.
