To provide a ventilation building for a building that is breathable and prevents rainwater from passing indoors.

<Embodiments> The present invention will be described in detail below based on embodiments of the drawings.

The board material 1 used for the ventilation building according to the present invention is the first
As shown in the figure, it consists of a plurality of vertical bars 2 arranged substantially in parallel, and a plurality of upper and lower side panels 3 fixed to the vertical bars 2 at right angles.

The vertical beam 2 supports each panel 3, and is made of a bar such as a C-shaped steel, and has panel fixing portions 4 at approximately equal intervals along the length of the surface. The face material fixing portion 4 shown in FIG. 1 consists of a positioning claw piece 5 cut and raised from the surface of the vertical beam 2 and a fixing claw piece 6.

If a plurality of fastening claw pieces 6 are provided in the longitudinal direction of the vertical beam 2, the face material 3 can be firmly fastened, and the fastening angle will not be distorted.

The above-mentioned face material 3 is formed by bending and forming a strip plate into a substantially Z-shaped cross section using a roll forming machine, for example, and has a horizontal fastening part 7 and an upper or lower side edge of the fastening part 7. A bent part 8 is formed by bending the bent part 8 diagonally along the length direction, and a ventilation part 9 is formed by bending the tip edge of the bent part 8 so that it is substantially parallel to the fastening part 7 along the length direction. In the fastening part 7, the receiving parts 10 of the face material fastening parts 4 are formed at approximately equal intervals corresponding to the arrangement spacing of the vertical bars 2. . The receiving part 10 shown in FIG. 1 is a long hole opened to a size that allows the fastening claw piece 6 to be inserted, and the side edge of the fastening part 7 is brought into contact with the positioning claw piece 5 and A fixing claw piece 6 is provided at a position such that when the material 3 is pressed against the vertical beam 2, the fixing claw piece 6 is inserted into the elongated hole.

Therefore, when assembling the plate material 1 constructed as described above, the vertical bars 2 are arranged at predetermined intervals, and the side ends of the face material 3, that is, the side ends of the fastening portions 7 are connected to the positioning claws. Insert the fastening claw piece 6 into the long hole that is the receiving part 10 in contact with the piece 5, and then bend the fastening claw piece 6 protruding from the surface of the face material 3 toward the positioning claw piece 5 side. The face material 3 may be fastened orthogonally to the vertical beam 2 by using the following method. Note that when the fastening claw piece 6 is bent in the direction of the positioning claw piece 5, the side end of the fastening part 7 does not separate from the positioning claw piece 5, so the face material 3 can be accurately fixed in a predetermined position. can be worn.

In this way, when a plurality of surface materials 3... are attached at different heights so that they are parallel to each other, each surface material 3...
All the ventilation portions 9 are directed in the same direction, for example, in the upper right direction in FIG. Also, the fixing interval between the vertically adjacent panel materials 3 is determined by the fixing distance between the fixing portion 7 and the ventilation portion 9 of the adjacent panel material 3.
The distance should be such that they are facing each other.

When the plate material 1 is assembled as described above, the plate material 1 is
It is possible to form a horizontally long ventilation hole 11 that connects the front side and the back side in a curved manner.

FIG. 2 is a cross section of a ventilation building 12 according to the present invention in which the plate material 1 having the above-mentioned structure is used as the first plate material 1a on the indoor side and the second plate material 1b on the outdoor side.
The plate material 1a has a vent hole 11a facing downward, and the second plate material 1b has a vent hole 11b facing upward.

In this ventilation ridge 12, the lower ends of the first vertical bars 2a, 2a are fixed to the vicinity of the inclined upper ends of the rafters 13, 13, and a fixing portion 7a is attached to the outdoor surface of the first vertical bars 2a.
The fixing portions 7 of the plurality of horizontally long first surface members 3a are attached with the ventilation portions 9a facing upward and the ventilation portions 9a facing downward
The first plate material 1a is located on the indoor side and the ventilation hole 11a faces downward by changing the height and fixing the parts a.
1a are arranged in parallel to face each other, and the rafters 15, 15 of the ridge roof 14 are fixed to the upper ends of the first vertical beams 2a.

Then, the second vertical bars 2b, 2b are hung from near the inclined lower end of the rafter 15, and the lower ends of the second vertical bars 2b, 2b are fixed to the roof board 17 with the support fittings 16,
On the outdoor surface of the second vertical crosspiece 2b, with the fastening parts 7b facing downward and the ventilation parts 9b facing upward, the fastening parts 7b of a plurality of horizontally long second panels 3b are attached to the height. By changing and fixing each first plate material 1a
A second plate member 1b is formed so as to be located on the outside of the room and have ventilation holes 1b facing upward. Therefore, the first board 1 on the indoor side
a and the second plate material 1b on the outdoor side have ventilation holes 11a,
11b are oriented upside down.

When the ventilation ridge 12 is configured as described above, the ventilation passage 18 formed between the sloped upper ends of the rafters 13, 13
The first plate members 1a, 1a facing the room A via
The first ventilation chamber B is in communication with the first ventilation chamber B surrounded by
and a second ventilation chamber C surrounded by the first plate material 1a and the second plate material 1b communicate with each other, and the ventilation holes 1 of the second plate material 1b communicate with each other.
The second ventilation chamber C communicates with the outdoors D through 1b..., and the width of the first ventilation chamber B is wider than the width of the second ventilation chambers C on either side.

Therefore, the air in the room A flows into the first ventilation chamber B through the ventilation path 18, and then flows into the left and right second ventilation chambers C through the ventilation holes 11a of the first plate 1a. Then, the ventilation hole 11b of the second plate material 1b...
It can be discharged to the outside D through the inside.

In general, indoor ventilation in a building with a ventilation ridge is caused by the temperature difference between the outdoors and indoors, and the action of the wind outside the room.

For example, if there is no wind and there is no temperature difference between the outdoor and indoor areas, or if the outdoor side is hotter than the indoor side, ventilation will not take place indoors, but if there is no wind and the indoor side is hotter than the outdoor side. If present, natural ventilation is provided by the rising air inside the room.

Therefore, when there is no wind and the temperature inside the room is higher than the temperature outside, the air inside the room rises, passes from the first ventilation chamber B to the second ventilation chamber C, and is discharged to the outside D.

Also, if wind or rain is blowing into the ventilation building,
One side of the outdoor side located on the windward side of the ventilation building is in a pressurized state, and the other side of the outdoor side located on the leeward side is in a reduced pressure state. Therefore, the second ventilation chamber C on the windward side
Since the second ventilation chamber C is narrower than the first ventilation chamber B, the second ventilation chamber C can sufficiently reduce the external pressure of strong winds and rain, and can also prevent strong winds and rainwater from flowing into the first ventilation chamber B. .

On the leeward side, the wind pressure acts on the ridge as a negative pressure, that is, a suction force, and the air inside the room is discharged to the outside by this suction force. In this case, the space in the first ventilation chamber B is wider than the space in the second ventilation chamber C, so D>A>B>C holds true in the spatial relationship between indoor A and outdoor D, and the indoor side Since the air is gradually constricted from the indoor room A to the first ventilation chamber B and the second ventilation chamber C, it is discharged to the outside D at once, so that the air passes smoothly and the ventilation effect is enhanced.

In addition, in the case of rainy weather, rainwater falling on the ridge roof 14 flows from the sloped lower end of the ridge roof 14 to the roof plate 17.
Since rainwater falls on the upper surface, indoor ventilation can be performed without rainwater flowing into the room from the ventilation holes 11b of the second plate member 1b. Then, in the case of rainy weather accompanied by wind, the wind
Since the raindrops blow up from the eaves toward the ridge on the surface of the roof, the raindrops blown by the wind collide with the face material 3b of the second plate material 1b located on the outdoor side from diagonally below.

As shown in FIG. 2, the face material 3b of the second plate material 1b has a bent portion 8b extending obliquely upward toward the outdoor side from the upper edge of the fastening portion 7b fixed to the second vertical beam 2b.
A ventilation section 9b stands up almost vertically from the upper edge of the bent section 8b. Further, the ventilation hole 11b formed between the face members 3b, 3b is bent downward into a hook shape from the outdoor side.

Therefore, when rainwater blows obliquely from below toward the second plate 1b, the wind passes through the ventilation hole 11b while bending and flows into the second ventilation chamber C, but most of the raindrops are directed toward the second plate 1b. The air flows down onto the roof panels 17 without flowing into the second ventilation chamber C. Most of the raindrops that curved through the ventilation hole 11b and flowed diagonally downward into the second ventilation chamber C, although few, fall onto the roof board 17 inside the second ventilation chamber C. Thereafter, it is discharged to the outside D through the gap between the bottom panel 3b and the roof board 17.

Further, when there are raindrops directly blowing onto the first plate material 1a in the second ventilation chamber C, the bent portion 8a of the face material 3a extends obliquely downward toward the outdoor side, and the ventilation portion 9a extends from the lower edge of the bent portion 8a. Since the raindrops hang down almost vertically, the raindrops hit the panel 3a and fall onto the roof board 17, and then the panel 3a and the roof panel 1
It is discharged to the outside D through the gap with 7. Therefore, raindrops do not reach the first ventilation chamber B, and the inflow of rainwater can be reliably prevented.

Ventilation building 12 according to the present invention configured as described above
Even if there is no wind, if there is a temperature difference between the outdoors and indoors, the polluted air in indoor A will be discharged to outdoor D, and even if there is wind blowing, rain or rain, rainwater will not flow into the indoor area. The air in the room A can be exhausted to the outside of the room.

<Effects of the Invention> As explained above, the present invention includes a plurality of vertical bars, a fixed part, a bent part formed by bending one of the upper and lower side edges of the fixed part along the length direction, and A horizontally long panel consisting of a ventilation section formed by bending the end edge of the bent part along the length direction is fastened in multiple pieces by changing the height of the attachment section, and a ventilation section is created between the vertically adjacent panels. With the above-described configuration, the first plates with the ventilation holes facing downward are arranged in parallel near the sloping upper end of the rafters of the main roof in an opposing manner, and the ventilation holes are facing upward. A second plate facing the left and right sides is arranged side by side on the outdoor side of each first plate, a ridge roof is provided at the upper end of each first plate and the second plate, and a first ventilation communicating with the room is provided within the opposing interval between the left and right first plates. A second ventilation chamber is formed between the first plate material and the second plate material to communicate the first ventilation chamber with the outdoors, and the width of the first ventilation chamber is larger than the width of the second ventilation chamber. Since it is characterized by being wide, it is possible to provide a ventilation building that allows indoor air to flow out to the outside very easily, ensures sufficient ventilation, and can reliably prevent rainwater from flowing in. In addition, indoor air and outside air pass through the first ventilation chamber and the second ventilation chamber during ventilation, but since the width of the first ventilation chamber is wider than the width of the second ventilation chamber, the passage of air is obstructed. The ventilation efficiency is always good regardless of the weather, especially in gymnasiums,
It can be effectively used in factories and other buildings with relatively large areas.
