Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a ventilation building formed by covering a water cutting board with a sewer cutting board.

[Background technology] In the past, draining plates were erected in the ventilation openings in the ridge of the roof that communicated with the attic, ventilation holes were bored in the draining plates, and the spaces between the draining plates were used as ventilation channels. In addition, ventilation channels are formed by covering the ventilation openings with drainage plates using long mounting materials, and ventilation covers are placed over these ventilation channels to form ventilation ridges. It takes time to erect the board, and if the draining board is installed using mounting materials, it becomes a problem to close the ventilation opening from rain, and a ventilation cover is also required.
The number of parts increased and the workability was poor.

[Purpose of the invention] The present invention was created in view of the above circumstances, and its purpose is to create a ventilation system that does not have any problem in closing the ventilation openings from rain, reduces the number of parts, and has excellent workability. The aim is to provide buildings.

[Disclosure of the invention] The ventilation ridge of the invention includes a ventilation opening 1 formed in the ridge part A of the roof and communicating with the attic B.
A drain plate 3 with a lower ventilation hole 2 that communicates with the drain plate 3 is covered, and an upper drain plate 5 with an upper ventilation hole 4 drilled in the drain plate 3 is covered with a spacer 6 interposed therebetween. The lower ventilation hole 2 then forms a ventilation flow path C leading to the upper ventilation hole 4 located closer to the eaves than the lower ventilation hole 2 in the direction of the eaves, and the ends of the upper drainage board 5 and the lower drainage board 3 in the direction of the eaves. A drainage gap 7 is formed in the section, and with this configuration, the above object can be achieved. That is, the upper drain plate 5 is placed over the lower drain plate 3 that covers the ventilation opening 1 via the spacer 6, and the ventilation passage C is formed between the upper drain plate 5 and the lower drain plate 3, and the drainage Since the space 7 is formed, the water that has entered from the upper ventilation hole 4 of the water draining plate 5 will be
Water is drained from the drainage gap 7, and there is no problem in closing the ventilation opening 1 from rain.Therefore, there is no need for a ventilation cover to prevent rainwater from entering, and the spacer 6 can also reinforce the water drainage plate 5. Therefore, the number of parts can be reduced and the workability is excellent.

The present invention will be described below based on embodiments shown in the accompanying drawings. In this embodiment, the roof is constructed by pasting waterproof plywood 8 on rafters 14, and covering the roof with a roof base material 9 and then with a roof material 10. In the ridge part A of the roof, the ends of the waterproof plywood 8, the roof base material 9, and the roof material 10 are attached with a predetermined distance apart to form a ventilation opening 1. The ventilation opening 1 is covered with a drainage board 3 which is elongated in the longitudinal direction of the ridge and has a substantially inverted V-shaped cross section with both sides in the direction of the ridge slanted along the roof slope. A substantially central portion of the drain plate 3 protrudes along the longitudinal direction of the ridge with a substantially inverted U-shaped cross section, facing the ventilation opening 1, and the protruding portion 11 is located at a predetermined location on both sides 20 of the raised portion. Cut and raise the ventilation openings 1 at specified intervals in the longitudinal direction.
A plurality of lower ventilation holes 2 communicating with the lower ventilation holes 2 are bored.
In addition, both ends of the sewage cutter plate 3 in the direction of the eave are bent downward into a substantially U-shape to form insertion recesses 12 that open laterally over the entire length.
A rubber waterproof gasket 13 is interposed behind the ventilation opening 1 over the entire length in the longitudinal direction of the ridge. The lower part of this waterproof packing 13 is the roofing material 10.
The upper part is made of soft rubber such as butyl rubber to ensure good adhesion to the body, and the upper part is made of hard rubber such as neoprene rubber to ensure shape retention. This sewer drain plate 3 is covered with a water drain plate 5 with a spacer 6 interposed therebetween. The upper drain plate 5 is wider than the lower drain plate 3, and has a substantially inverted V-shaped cross section with both sides in the direction of the ridge eaves sloping along the roof slope, and is cut and raised at a predetermined point to extend the entire length in the longitudinal direction of the ridge. A plurality of upper ventilation holes 4 are bored in parallel at predetermined intervals, and both ends are L-shaped pieces 18 bent downward into an L-shape. Spacer 6
are U-shaped and are arranged at predetermined intervals in the longitudinal direction of the ridge, and the lower horizontal piece 15 is inserted into the insertion recess 12 of the sewage cutting board 3, and the upper horizontal piece 16 is inserted from the tip of the upper horizontal piece 16. A reinforcing piece 22 having a continuous leg piece 21 is brought into contact with the back surface of the water cutting plate 5, and a drainage space is created between the L-shaped piece 18 of the water cutting plate 5 and the end of the sewer cutting plate 3. 6
is formed and riveted to the water drain plate 5. A heat insulating material 17 is interposed between the upper drain plate 5 and the protrusion 11 of the lower drain plate 3. In this embodiment, the sewage cutting board 3 and the water cutting board 5 are integrated with a spacer 6 before construction, and stainless steel nails 1 with washers and seals are installed at the site.
9 is inserted into the ventilation opening 1 by penetrating the waterproof gasket 13 from the water cutter plate 5, and inserting it into the ventilation opening 1.
A ventilation flow path C is formed from the lower ventilation hole 2 to the upper ventilation hole 4 located closer to the eaves than the lower ventilation hole 2 in the direction of the eaves. Therefore, the air in the attic B flows to the outside through the ventilation opening 1, the lower ventilation hole 2, the upper ventilation hole 4, and the partial drainage gap 7, as shown by the arrows in the figure, and the outside air flows in the opposite direction. Flows on the course. In addition, rainwater that has entered through the upper ventilation hole 4 of the water drain plate 5 is drained to the outside from the drainage hole 7, so that even if rainwater rises through the drain plate 3 during a rainstorm, etc.
The side piece 20 of the protrusion 11 prevents the water from entering the ventilation opening 1 from the lower ventilation hole 2, and the water flows down the drain plate 3, drains outside from the drainage space 7, and enters the attic B. Never.

[Effects of the invention] In the present invention, a drainage board covered with a ventilation opening is covered with a drainage board with an upper ventilation hole drilled therein, with a spacer interposed between the drainage opening and the lower ventilation hole, and then the upper ventilation hole. In addition to forming a ventilation flow path leading to the ventilation hole, there is a drainage gap at the end of the upper and lower drainage boards in the direction of the eaves.
As a result, not only can the attic be ventilated through the ventilation channel, but water that has entered through the upper ventilation hole of the upper drainage board can be used for drainage without going to the lower ventilation hole of the drainage board. Water drains from the roof, does not enter the attic through the ventilation openings, and there is no problem in closing the ventilation openings from rain.Therefore, there is no need for ventilation covers to prevent rainwater from entering. Since the water drain plate can be reinforced with the spacer, the number of parts can be reduced and the workability is excellent.
