Description

  The present invention relates to a mounting structure for a ventilation device for a house building that is installed by placing the bottom plate side on a roof tile constructed near the building as a ventilation device for taking in and out air indoors and outdoors.

  Conventionally, as a ventilation device for a house building part, a substantially umbrella-shaped top plate extending from the sloped roof building part to the roof surfaces on both sides, and a bottom plate on both sides facing the plate surface of the top board while maintaining a predetermined ventilation interval It is formed from a plurality of baffle plates standing alternately inside the ventilation interval from the top plate and bottom plate surfaces, and the outdoor side vent is opened to the lower end side of the top plate and bottom plate. A configuration in which the mouth is configured to open to the upper end side of the bottom plate is known (Patent Document 1).

  The ventilator for the house building is designed so that the indoor vent is aligned with the vent of the ridge, the ventilation vent of the ridge is covered with the top plate, and indoor and outdoor air is taken in and out of the vent on the outdoor side. Since it is installed on the bottom side of the roof on the bottom plate side, it is configured exclusively for roofing with flat roof tiles.

  Even with the ventilation system for the house building, if the base plate is attached and fixed with a stopper that rises from the roof of the sloped roof toward the top plate, it is applied to the wavy roof tiles that are constructed near the building. Can be installed.

When the bottom plate side is installed on the corrugated roof tile, a gap is formed between the corrugated surface of the roof tile and the bottom plate side of the ventilation device. For this reason, it is necessary to pack caulking materials such as plaster in the gap or to close the gap by assembling a face door plate having a shape corresponding to the wave upper surface of the roof tile. However, it takes a lot of work for each construction.

Is installed on the roof surface of both sides as a gap cover between the corrugated surface of the roof tile and the corrugated surface of the roof tile and the roof ground surface and the bottom plate side of the ventilator. To do.

  According to the mounting structure of the ventilation device for a house building according to the present invention, the standing of the water stop to be installed from the both grounds of the roof as a drainage cutout for the gap between the corrugated surface of the roof tile and the bottom plate side of the ventilation device. Since it is covered with a wall plate, rainwater entering from the gap between the corrugated surface of the roof tile and the bottom plate side of the ventilation device can be blocked. Even if rainwater enters the device side from the standing wall plate of the water stoppage due to the wind, the drainage enclosed by the water stop on both sides is provided on the inside, so rainwater can penetrate into the indoor side. It can be surely prevented.

During the construction, the drainage can be installed by installing the installation plates on both sides of the roof and installed from the ventilation opening of the ridge, and the drainage stopper can be installed on the roof with the installation plate overlapping the drainage installation plate. Since it only has to be installed from the roof surfaces on both sides as a gap between the corrugated surface of the roof tile and the corrugated surface of the roof tile and the roof ground surface, it does not take time for any mounting work.

In the illustrated embodiment, in a sloped roof in which corrugated roof tiles R ₁ are laid on the base plate B and a round crown tile R ₂ is installed in the ridge, indoor and outdoor air is supplied from the ventilation vent F of the ridge. It is configured to be housed and arranged inside the crown tile R ₂ as a ventilation device 1 for a ridge portion of a house to be taken in and out.

The ventilator 1 is attached and fixed with a stopper 2 that rises from the ridge part of the sloped roof toward the top plate, and the bottom plate side is applied to the corrugated roof tile R ₁ that is constructed on the roof surface near the ridge part.

The vent 15 on the outdoor side is provided with an upright standing wall plate 11a by bending a plate surface near the lower end of the bottom plate 11, and a front plate 11b inclined downward from the upper end side of the standing wall plate 11a. The plate surface 10e is bent to be narrower than the ventilation interval 14 because the plate surface 10e is bent from the slope plate 10d having a downward slope and is parallel to the plate surface of the bottom plate 11 and maintains a predetermined distance from the standing wall plate 11a. Has been.

  An indoor vent 16 is formed near the upper end of the bottom plate 11. The indoor side air vent 16 bends the plate surface closer to the upper end of the bottom plate 11 as a rising plate 11c having the same height as the rising sides 13b, 13c of the baffle plate 13, and is thus spaced apart from the rising side 12c of the baffle plate 12. The innermost baffle plate is formed.

  The ventilation space 14 and the ventilation holes 15 and 16 are spaced from each other because the support pins 17 (see FIG. 1) are riveted to the upper side of the top plate 10 and the bottom plate 11 and the spacer 18 is fixed to the lower side. Is retained. A plurality of support pins 17 and spacers 18 are attached side by side in the longitudinal direction of the top plate 10 and the bottom plate 11.

  The spacer 18 includes a standing plate 18a bent in a U-shape, stopper pieces 18b and 18c bent outward at the free end side of the standing plate 18a, and a fitting plate 18c bent so as to overlap the standing plate 18a. And is formed from.

  In the spacer plate 18, the standing plate 18a is fitted between the gutter plate 10e of the top plate 10 and the plate surface of the bottom plate 11 through the opening 11d provided in the standing wall plate 11a of the bottom plate 11, and the stopper pieces 18b and 18c are opened in the opening 11d. In addition to being hooked on the rim of the mouth plate, the attaching plate 18c is assembled with the plate 10e of the top plate 10 by rivets.

  As shown in FIG. 3, the fastener 2 is formed by bending a relatively thick metal flat strip. The fastener 2 includes leg pieces 20a and 20b on both sides, leg plates 21a and 21b that stand up and face each other from the leg pieces 20a and 20b, and bridge plates that extend between the upper ends of the leg plates 21a and 21b. 22. The bridge plate 22 is formed in a U-shape by dropping from the upper end side of each leg plate 21a, 21b.

  As shown in FIG. 4, the drainer 3 includes a width corresponding to the interval between the leg plates 21 a and 21 b of the stopper 2, a length corresponding to the longitudinal direction of the vent F (see FIG. 1), and a stopper. A rectangular enclosure 30 having a lower height than the two bridging plates 22 is formed as a main body. In addition, a top plate portion 32 provided with a plurality of elongated holes 31a, 31b in the longitudinal direction, and installation plates 33a, 33b on both sides projecting diagonally outward from the lower end in the longitudinal direction of the surrounding frame 30 are formed. Has been.

  As shown in FIG. 5, the water stopper 4 includes a standing wall plate 40 having a rising substantially corresponding to the undulation height of the roof tile, and a support plate 41 that is bent from both ends of the standing wall plate 40 to both ends in the longitudinal direction of the drainage 3. One side is omitted) and a mounting plate 42 that is bent outward at a substantially right angle from the lower end in the longitudinal direction of the standing wall plate 40. As this water stop 4, two things of the same structure are prepared so that it may install in the roof surface of both sides.

  The standing wall plate 40 bends the support plate 41 from the substantially middle side of the rising width so that the upper side faces the longitudinal direction of the drainage 3 in an attached state so as to impart rigidity that can resist wind swell. It is bent in a dogleg shape along the longitudinal direction in the same direction as the direction.

  Further, the bending angle with the support plate 41 is cut from the upper end side to the bending portion in the longitudinal direction, and the plate surface of the support plate 41 is made up with the standing wall plate 40 by the bending allowance corresponding to the folding of the character. It is configured to bend in the relative direction and bend and hold the bent portion of the support plate 41 by bending the upper end side of the standing wall plate 40 inward.

  When the above-described components are provided, first, as shown in FIG. 6, the enclosure frame 30 is aligned with the ventilation opening F of the ridge, and the installation plates 33a and 33b are applied to the plate surface of the base plate B, and then drained. 3 is installed in the ridge of the sloped roof. This drainer 3 is installed by installation plates 33a and 33b so that the enclosure frame 30 rises in the vertical direction from the ventilation opening F of the ridge.

  Next, the drainer 3 is received inside the leg plates 21a and 21b, and the foot pieces 20a and 20b are placed on the mounting plates 33a and 33b and fixed to the plate surface of the base plate B by fixing them. Attach the bracket 2 together with the drainage 3 to the ridge of the sloped roof. The fasteners 2 may be attached to about three pieces at a predetermined interval in the longitudinal direction of the drainage 3.

  As shown in FIG. 7, the sleeper 5 is fitted into the U-shaped bridging plate portion 22 and fixed with a nail from the side, so that the longitudinal direction of the ventilation opening F is disposed on the upper side of the drainage 3. Attach it over the At this time, since the bridging plate portion 22 of the stopper 2 is formed in a U shape, the sleepers 3 can be easily fitted and fixed by being fitted into the U.

After or before the sleeper 5 is attached, the water stoppers 4, 4 'are installed on the roof surfaces on both sides as shown in FIG. The water stoppers 4 and 4 ′ stand so that the standing wall plate 40 can come into contact with the upper end surface of the roof tile, and the support plates 41 and 41 ′ are relatively aligned with each other at both ends in the longitudinal direction of the drainage 3. Since the installation plates 42 and 42 ′ overlapping the installation plates 33 a and 33 b of the drainer 3 are attached to the roof field B, the space between the corrugated surface of the drainage 3 and the roof tile R ₁ and the roof field B It is installed as a gap cover.

  Since the support plates 41 and 41 'are installed on the roof surface B by being relatively aligned with each other at both ends in the longitudinal direction of the drainage drain 3, they are pushed even if the standing wall plates 40 and 40' are blown by wind. The standing wall plate 40 is supported so as not to be displaced. In addition, the waterproof seal 6 (see FIG. 1) may be applied along the matching edge between the installation plate 33a and the installation plate 42. Thereby, even if rainwater enters the apparatus side from the standing wall plates 40, 40 'of the water stoppers 4, 4' by wind, it can be prevented from entering the roof field side.

The following is Shikikomi construction on both sides of the wavy roof tiles R ₁ a pitched roof as shown in Figure 9. Among the roof tiles R ₁ , those to be constructed on the roof surface near the ridge are laid with the upper end surface in contact with the lower half plate surface of the standing wall plate 40. Thereafter, the ventilation device 1 is placed on both sides of the sloped roof over the sleepers 5. This ventilation device 1 can be easily positioned and fixed by nailing since the top portion 10a bent in a U-shape is fitted from above the sleepers 5.

In the mounting state of the ventilator 1, since the Ategau the roof tile R ₁ near the ridge by the rising height of the studs 2 a bottom plate 11, the whole of the ventilation device 1 is installed. Further, the standing wall plate 40 of the water stopper 4 is erected so as to reach the vicinity of the upper end of the bottom plate 11.

Finally, since the assembled plurality of Kanmurikawara R ₂ in the longitudinal direction of the ridge portion as shown in Figure 10, may be positioned accommodated the entire apparatus inside the Kanmurikawara R _2. The Kanmurikawara R ₂ suffers until eaves plate 10e of the top plate 10, the outer vent 15 is dimensioned so as to be exposed to the outside from Kanmurikawara R _2. In addition, the roof tiles are arranged in a straight line on the ridges extending on both sides of the ventilation device 1.

  In the house building ventilation device, outdoor air is taken from the outdoor vent 15, flows through the ventilation interval 14, flows from the indoor vent 16 to the ventilation vent of the building, and passes indoor air through the reverse path. Since air is discharged from the vent 15 on the outdoor side, indoor and outdoor air can be ventilated.

  By taking in the outdoor air, the wind with rainwater is formed so that the outdoor vent 15 is narrower than the ventilation interval 14 from above to the vent 15 on the outdoor side. Less wind intrusion. About the wind which goes upwards from the downward direction of a sloped roof, since it can be swung up by the front part board 11b which exhibits an up-slope toward the upper end side of the standing wall board 11a, it can prevent flowing into the vent 15 on the outdoor side.

  Even if the wind with rainwater enters the ventilation interval 14 from the vent 15 on the outdoor side, it flows while meandering on the baffle plates 12b, 12c, 13b, 13c, so that the rainwater is drained. Further, even if rainwater is not completely drained by the baffle plates 12b, 12c, 13b, 13c, the rainwater is blocked by the drainage drain 3, so that it does not reach the ventilation opening of the ridge. Therefore, it is possible to reliably prevent rainwater from entering the ventilation opening of the ridge along with the outside air.

The gap between the bottom plate side of the wave Okoshimen the ventilator 1 of roof tile R ₁ is is covered with the 'standing wall plate 40, 40' entering water stop 4,4 as water discard cutting enclosing combined, the gap More rainwater can be blocked. Even if rainwater enters the equipment side from the standing wall plates 40, 40 'of the water stop 4, 4' due to the wind, the drainage drain 3 is provided on the inside, so that rainwater enters the indoor side. I can definitely prevent it.
