[Background technology]

*Various ventilation devices are used to improve ventilation indoors. In particular, an attic ventilation system that can quickly exhaust hot air from the attic space under the roof to the outdoors is installed in the ridge or between the roof of a partial one-story building and the outer wall of the upper floor. However, if the attic ventilation opening is opened in such a location, rainwater may blow into the attic from the attic ventilation opening. For this reason, a water return piece is erected from the green of the attic ventilation hole to the top of the roof so that it is tilted to the opposite side from the attic ventilation hole, and a covering piece is installed from the top of the water return piece to cover the upper part of the attic ventilation hole. A ventilation hole is formed in the water return piece, which extends in a substantially horizontal direction, to prevent rainwater from flowing into the attic ventilation opening. However, the water return piece 3 has poor strength because the hole 5 is perforated, and if a worker on the roof steps on this part, the water return piece 3 will be stepped on immediately and fall down. As a result, the ventilation hole 5 is blocked, resulting in poor ventilation in the attic.

[Purpose of the invention]

The present invention was made in view of the above-mentioned technical background, and its purpose is to prevent the water return piece from being crushed and blocking the ventilation hole even if the water return piece is stepped on. The goal is to make sure that you don't get caught.

[Disclosure of the invention]

The attic ventilation system of the present invention has an attic ventilation opening 2 opened in a roof 1, and a substrate 1 on the surface of the roof 1 on the side of the attic ventilation opening 2.
4, and tilt it to the opposite side from the attic ventilation opening 2, and install the water return piece 3 upright on the edge of the attic ventilation opening 2 side of the board 14, and attic ventilation from the upper end of the water return piece 3. In an attic ventilation system in which a covering piece 4 covering the upper part of the opening 2 extends substantially horizontally and a ventilation hole 5 is bored in the water return piece 3, the surface of the water return piece 3 on the opposite side from the attic ventilation opening 2. A spacer 6 for preventing the water return piece 3 from falling is brought into contact with the spacer 6, and a leg piece 22 is made to protrude from the lower surface of the spacer 6 to form a ventilation space 23 between the lower surface of the spacer 6 and the substrate 14. It is characterized by: However, in the present invention, since the water return piece 3 is supported on the lower side by the spacer 6, even if it is stepped on by a worker on the roof, it will collapse and the ventilation hole 5 will be blocked. The ventilation hole 5 can be kept well ventilated in the attic space without being leaked, and since the leg piece 22 is made to protrude from the lower surface of the spacer 6 to form the ventilation space 23, the ventilation hole 5 can be kept well ventilated. There is an advantage that the passed exhaust gas passes through the lower surface of the spacer 6 and is smoothly exhausted.Examples of the present invention will be described below in detail with reference to the attached drawings. The attic ventilation system of the present invention is constructed in the ridge part of the roof of a house. That is, the roofing board 8 and the roofing material 9 are placed on the rafters 7 arranged on both sides of the ridge with a roof slope. Thatch (sometimes, a space is left between the edges of the roofing board 8 and the roofing material 9 to form an attic ventilation opening 2 in the ridge. Therefore, moisture and hot air in the attic space 10 under the roof 1 are removed. is discharged above the roof 1 through the attic ventilation opening 2.Packs 11 are installed on the upper surface of the roofing material 9 on both sides of the attic ventilation opening 2.
A waterproof board 12 is placed on the floor and fixed to the roof material 9 with nails 13. The waterproof board 12 has a water return piece 3 erected at the tip of the attic ventilation opening 21Ill of the base plate 14 which is arranged along the roof material 9 and fixed to the roof material 9, and a water return piece 3 is installed from the upper end of the water return piece 3. The cover piece 4 is further extended in parallel with the substrate 14, and is formed by bending a metal plate. The water return piece 3 has fallen to the board 14IIi (the side opposite to the attic ventilation opening 2), and the area around the water return piece 3 has a Z-shaped cross section, and the water return piece 3 has a long ventilation hole 5. There are multiple holes. Partition pieces 15 are erected at both ends of the board 14 to prevent rainwater that has entered onto the waterproof board 12 from flowing into the adjacent waterproof board 12 from both ends of the board 14. In this way, the waterproof plates 1 arranged on both sides of the attic ventilation opening 2
Since an opening is formed between the tips of the two cover pieces 4, a band-shaped sheet 16 having visibility and heat insulation properties is pasted between the tips of the cover pieces 4 to close this gap. The spacer 6 that supports the water return piece 3 is located at the same angle as the water return piece 3 from the flat rear upper surface 17. A front upper surface 18 extends, and a wide notch 19 is recessed in the front upper surface so as to face the ventilation hole 5 of the water return piece 3. Further, side skirt pieces 20 are suspended from the side ends of the front and rear upper surfaces 18 and 17, and a rear skirt piece 21 is suspended from the rear end of the rear upper surface 17. Further, a pair of plate-shaped leg pieces 22 are provided on the lower surface of the spacer 6, and ventilation spaces 23 are formed on both sides of the leg pieces 22 to allow ventilation in the front-rear direction. The spacer 6 protrudes further downward than the skirt pieces 20 and 21 to prevent the area around the spacer 6 from being blocked by the skirt pieces 20 and 21, thereby ensuring air permeability. Further, on both sides of the back surface of the spacer 6, joint grooves 24, which are wider at the back, are provided along the entire length of the upper and lower sides. This spacer 6 is a waterproof board 1 arranged on both sides of the attic ventilation opening 2.
2, the front upper surface 18 is pushed into the lower surface of the water return piece 3, and the position of the notch 19 matches the position of the ventilation hole 5 of the water return piece 3, so that the ventilation hole 5 is It is placed so that it is not blocked by spacer 〇. What is shown in FIGS. 7 and 8 is a fixing block 25 for fixing the spacer 6, and the distal end of the fixing block 25 has a wide tip and a groove 25 for fixing the spacer 6. A protrusion 26 for 7 summer India is provided which can be engaged with the protrusion 26 for 7 summer India, and a nail hole 28 penetrating vertically is bored in the cylindrical part 27 behind the protrusion 26 for 1 in F. A roughly box-shaped temporary fixing part 29 is provided at the rear, and a through hole 30 is bored in the bottom and back surface of the temporary fixing part 29. Therefore, as shown in FIG.
The fixing block 25 is connected to the spacer 6 by fitting the spacer 6 into the chisel-in groove 24 from above. At this time, it is also possible to temporarily fix the fixing block 25 by driving screws or the like into the waterproof plate 12 through the through hole 30 in the bottom of the temporary fixing part 29. What is shown in FIG. 10 is a metal ridge material 31 that constitutes the appearance of the ridge. A chevron portion 32 is bent in a substantially U-shape according to the slope of the roof, and draining portions 33 are provided in a step-like manner on both sides. There are rain shelters on both sides of the chevron 32.
A ventilation hole 36 with a plurality of through holes 3 is provided.
4 is perforated. Thus, the metal ridge material 31 is placed on the top surface of the cover piece 4 of the waterproof board 12 and the top surface of the spacer 6, and the draining part 33 is attached to the base plate 14 of the waterproof board 12 through the partially disposed gasket 37. placed on top. At this time, the inner surface of the draining part 33 of the metal ridge material 31 is positioned in contact with the back surface of the temporary fixing part 29 of the spacer 6, and the through hole 34 is located below the water than the spacer 6, as shown in FIG. The through hole 34 faces the nail hole 28 of the spacer 6. In this state, as shown in FIG. 7, a large nail 39 with a soft packing 38 attached to the upper end is passed through the hole 30 of the metal ridge material 31 and into the nail hole 28 of the spacer 6. The metal ridge material 31 and spacer 6 are fixed by driving into the timber 9, the roofing board 8, and the rafter 7. In this way, when the nail 39 is driven in, the soft packing 38 is compressed by the head of the nail 39 and the metal ridge material 3
It is pressed against the edge of the first through hole 34, and water is prevented from entering through the green through hole 34. Furthermore, it is also possible to fix the spacer 6 to the metal ridge material 31 by driving screws or the like from the draining part 33 of the metal ridge material 31 to the back side of the temporary fixing part 29 of the spacer 6. Therefore, the air containing moisture in the attic space rises through the attic ventilation opening 2 as shown by the solid arrow in FIG. It passes through the ventilation space 27 on the lower surface of the spacer 6 and is exhausted outdoors from the ventilation hole 36 of the metal ridge member 31. On the other hand, as shown by the dashed arrow in Fig. 1, the metal ridge material 3
Rainwater that has entered through the ventilation holes 36 flows downward along the rain shelter 35, passes through the lower surface of the draining portion 33 of the metal ridge member 31, and is discharged to the surface of the roof material 9. Also,
Even if there is a lot of rainwater blowing in, the water return piece 3 is raised on the upper end side of the board 14 and the ventilation hole 5 is bored in the water return piece 3, so there is no risk of rainwater entering through the ventilation hole 5. It looks like this. Further, the water return piece 3 is not crushed and fallen down due to the vicinity of the water return piece 3 being exposed from above the metal ridge material 31, and the ventilation hole 5 is not blocked. Along the longitudinal direction of the roof ridge, the attic ventilation systems having the above structure are arranged adjacent to each other at regular intervals, and the partition pieces 15 are erected at both ends of the waterproof board 12 as described above. Because each attic ventilation system is independent, rainwater does not flow in from the adjacent attic ventilation system, and rainwater does not collect in one place in the ridge, preventing rainwater from overflowing. can be prevented. What is shown in FIG. 11 is the other side of the present invention, in which the waterproof plates 12 on both sides of the attic ventilation opening 2 are integrally formed so as to straddle the ridge part, and the cover pieces 4 of the waterproof plates 12 on both sides are integrally formed. The tips are continuous. The water return piece 3 of this waterproof board 12 is supported by a spacer 6, and the spacer 6 is fixed by a fixing block 25, which is the same as in the first embodiment, but instead of using the metal ridge material 31, A ridge tile 40 is used. That is, the support part 41 is provided on the upper surface of the cover piece 4 of the waterproof board 12, and on this! 1! It has a structure on which a commercial round ridge tile 40 is placed. Circular ventilation holes 36 are opened at appropriate intervals on the top surface of the ridge tile 40, and above the ventilation holes 36, a perforated plate 42 for both roads as shown in FIG. 12 is attached with screws 43. There is. Therefore, the exhaust gas coming out from the ventilation hole 5 is connected to the spacer 6.
It passes under the ridge tile 40 and is discharged to the outside air from the vent 36 of the ridge tile 40. Further, rainwater blown into the ridge tile 40 from the vent 36 flows from the cover piece 4 to the upper surface of the spacer 6 and is discharged from the lower surface of the lower end of the ridge tile 40 to the outside. Moreover, although rainwater runs down the top surface of the spacer 6, since the side skirt pieces 20 and the rear skirt pieces 21 are suspended from both sides and the back of the spacer 6 as described above, the rainwater runs down the top surface of the spacer 6. is both skirt pieces 20.21
Water is reliably drained at the lower end, and rainwater is prevented from flowing along the lower surface of the spacer 6 toward the front end and reaching the vicinity of the ventilation hole 5. Note that a heat insulating sheet 16 is pasted on the lower surface of the cover piece 4 to prevent condensation.
Although it has almost the same configuration as the example, it is constructed on a roof with a large slope, and the ridge tile 40 does not have a ventilation hole 36 (
, the exhaust gas discharged from the ventilation hole 5 of the water return piece 3 is connected to the ridge tile 40.
It is designed to be discharged to the outside air through a gap on the bottom surface of the bottom end. The one shown in Figure @14 is a fourth embodiment of the present invention, in which ventilation of the attic space of a partial one-story building is performed in the outside part of the second floor at 9!44. That is, the attic ventilation opening 2 is opened between the outer wall 44 of the second floor and the partial one-story roof 49, and a structure similar to one half of the attic ventilation system shown in the first embodiment is installed in this part. The waterproof plate 1 of the first embodiment
A fixing piece 45 is raised at the upper end of the cover piece 4 having a structure similar to that of 2, and is fixed to the outer wall 44 with nails 46.
Furthermore, a fixing piece 48 is extended from the upper end of an exterior draining plate 47 which has a similar structure to one half of the metal ridge material 31. ! ! 4
It is fixed at 4. [Effects of the Invention] The present invention is constructed as described above, so a spacer for preventing the water return piece from falling is brought into contact with the surface of the water return piece opposite to the attic ventilation opening. supports one piece,
Even if someone steps on the roof, it won't collapse and block the ventilation holes (it has the advantage of keeping the attic space well ventilated. Since the ventilation space is formed on the lower surface of the spacer, the exhaust gas that exits the ventilation hole is discharged to the outside through the ventilation space and into the spacer, and the provision of the spacer has the advantage that ventilation is not obstructed.
