Description

[Detailed explanation of the invention] This invention is based on a ventilation roof, more specifically, a box-shaped ventilation ridge with an opening at the bottom and a ventilation hole on the side, which is arranged along the longitudinal direction of the roof ridge, allowing ventilation through the ventilation hole. A roof that ventilates outside air taken into the building from between the rafters to the attic.

In the conventional ventilation roof of this type, as shown in FIG. Since the ventilation between the attic and the ventilation ridge 2 was carried out through the space between the ridge ridges 25, the ridge ridge 25 obstructed the ventilation, and the width of the ventilation ridge 2 was required to ensure sufficient ventilation. It became necessary to widen the structure, and the structural members became large. In addition, it was necessary to fix the ridge pier 25 to the rafters 4, and to fix the drainer 6 and the ventilation ridge 2 to the ridge ridge 25 with fixing tools 13 such as nails, making the construction time-consuming. .

The present invention was developed in view of the above points, and its main purpose is to provide sufficient ventilation between the ventilation ridge and the attic using relatively small structural members. Among other things, another objective is to provide a ventilated roof that is easy to construct.

Hereinafter, embodiments of the present invention will be described based on the drawings. The ventilation roof according to the present invention has a box-shaped ventilation ridge 2 whose lower surface is open and a ventilation hole 1 is provided on a part of the side surface, which is arranged along the longitudinal direction of the ridge of the roof 3, and the ventilation hole 1 is passed through the ventilation ridge. The ventilation ridge 2 has a first horizontal piece 20 extending outward at the lower end, and a tip of the first horizontal piece 20. The lower end of the engaging portion 21 is folded inward to form a recess 5 that opens upward.
is formed, and a drainer 6 is fixed to the roof 3 on both sides of the ridge along the longitudinal direction of the ridge, a vertical piece 7 extends upward from the drainer 6, and the tip of the vertical piece 7 is folded back to the outside. A second horizontal piece 19 is extended, and an engaging piece 8 that projects downward is formed at the tip of the second horizontal piece 19, and when the engaging piece 8 is accommodated in the recess 5, the drainer 6 The ventilation ridge 2 is connected, and both ends of the rain cutter 22 which is arranged in the ventilation ridge 2 at a position corresponding to the ventilation ridge 1 and covers a part of the ridge of the roof 3 are connected to the first horizontal piece 20 of the ventilation ridge 2. Second component 19 of drainer 6
It is sandwiched between. As shown in FIG. 2, it is constructed by connecting two ventilation buildings with a base body 10. The ridge joint 10 has ventilation holes 1a on both sides in the width direction, and the ridge body 9 has a ventilation hole 1b attached to one side in the longitudinal direction. A support body 11 formed by bending a strip is disposed inside the ridge body 9. The support body 11 has substantially the same shape as the inner peripheral surface of the ridge body 9, and a fixing piece 12 provided at the lower end fixes the rafter 4 with a fixing member 13 such as a nail. An L-shaped holding piece 14 protrudes from the side surface of the support body 11 to form a holding recess 15 opening at the bottom. drainer 6
is arranged over almost the entire length of the ridge in the longitudinal direction, and the tile 1
It is fixed with a fixture 13 to a hole 17 fixed on the top 6. A vertical piece 7 extends from one end of the drainer 6, and the tip of the vertical piece 7 is folded back to form a fitting part 18. The fitting part 18 is housed in the holding recess 15, and the drainer 6 is connected to the support body 11. A horizontal piece 19 further extends outward from the fitting portion 18, and an engaging piece 8 hangs down from the tip of the horizontal piece 19. Further, a horizontal piece 20 extends outward from the lower end of the ventilation ridge 2, and from the tip of the horizontal piece 20, an engaging portion 21 is formed in which the lower end is folded inward and a recess 5 is formed that opens upward. Extends downward. The horizontal piece 20 of the ventilation ridge 2 is placed on the lateral piece 19 of the drainer 6, and the engagement piece 8 is housed in the recess 5 to connect the drainer 6 and the ventilation ridge 2, and the ventilation ridge 2 is placed on the roof. It is fixed at 3. on the other hand,
A rain gutter 22 is disposed within the ridge joint 10 to prevent rain blown from the ventilation opening 1a from penetrating into the attic. Both ends of the rain drainer 22 in the width direction are held between the ventilation ridge 2 and the drainer 6. That is, the rain gutter 22 is arranged to cover a part of the ridge of the roof 3, and its both ends are sandwiched between the horizontal piece 20 of the ventilation ridge 2 and the horizontal piece 19 of the rain gutter 6. At the time of construction, if the ventilation ridge 2 is connected to the drainer 6 after placing the rain drainer 22 on the drainer 6, the rain can be drained at the same time as the ventilation ridge 2 is fixed to the drainer 6 without using any special fixing equipment. 22 is fixed to the roof 3. In the figure, 23 is a roofing board, and 24 is a roofing. As described above, outside air is taken into the ventilation ridge 2 from the ventilation gate 1, passes between the rafters 4, and is ventilated into the attic to ventilate the attic.

As mentioned above, in the present invention, the lower end of the ventilation ridge is folded inward to form a recess that opens upward.
The tips of the vertical pieces extending upward from the drainers fixed on both sides of the ridge are folded back to the outside to form engagement pieces that protrude downward, and the engagement pieces fit into the recesses. Since the ventilation ridge is connected to the drain, the ventilation ridge can be fixed on the roof without using ridge beams, and sufficient ventilation can be achieved between the ventilation ridge and the attic without increasing the width of the ventilation ridge. This has the advantage that the attic can be ventilated efficiently while using relatively small structural members.
In addition, the ventilation ridge is fixed on the roof simply by engaging the recess of the ventilation ridge with the engaging piece of the drainer, so there is no need to construct a ridge ridge, and no fixing devices are required to fix the ventilation ridge. This has the advantage of simplifying construction. Furthermore, the ventilation ridge includes a first horizontal piece extending to the lower end, vertical pieces extend upward from drainers provided on both sides of the ventilation ridge, and tips of the vertical pieces are folded back to the outside to form a first horizontal piece. The second horizontal piece is extended, and both ends of the rain gutter are arranged in the ventilation building at positions corresponding to the ventilation grate and cover a part of the roof ridge. Since it is sandwiched between the horizontal piece of the rain gutter, if you place both ends of the rain gutter on the gutter during construction and then connect the ventilation ridge to the gutter,
This method has the advantage that the rain gutter can be fixed to the roof at the same time as the ventilation ridge is fixed to the gutter without using special fixing tools, and the work of installing the rain gutter becomes easy.
