Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building ventilation structure capable of ventilating a building ridge by natural convection.

[0002]

2. Description of the Related Art Conventionally, there have been provided various types of ventilation for the back of a building, which allows natural ventilation of hot air by natural convection of hot air. For example, one that forms a ventilation path between the roof panels facing each other in the ridge, and discharges the hot air inside the attic from the ridge cover part arranged in the ridge to the outside through this ventilation path. is there.

[0003]

By the way, the temperature of the roof panel itself rises remarkably in the summer and the like, which causes the temperature in the attic to rise.
Here, it is possible to suppress the temperature rise in the attic as much as possible by ventilating between the base and the roof tile that make up the roof panel, but in the conventional example as described above, Only the back ventilation was possible, and the ventilation performed by discharging hot air was not sufficient.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and provides a ventilation structure for a ridge part that allows the ventilation of the back side of the attic and the roof tiles to be performed together in the ridge by natural convection. It is what

[0007]

The present invention will be described below in detail based on the illustrated embodiments. The roof of the building is composed of a plurality of roof panel bodies 1, and the roof panel bodies 1 are arranged in the ridge portion such that a gap a is provided between the roof panel bodies 1 facing each other. The roof panel body 1 is a frame body 1d formed by frame-forming a frame material 1c having a U-shaped cross-section in a rectangular shape in plan view, a base body 1a provided on the frame body 1d, and a roofing on the base body 1a. The main body is constituted by the corrugated tile 1b provided. A water bar 4 having an L-shaped cross section is provided at the ridge-side end of the base body 1a, and a fixing member 5 that fixes the ridge-side end of the corrugated tile 1b is provided below the water bar 4. . The lower surface of the fixing member 5 is provided with an uneven portion 6 that matches the corrugated shape of the corrugated roof tile 1b so that the ridge-side end of the corrugated roof tile 1b can be fixed without deforming the corrugated roof tile 1b. It has become. A third air passage C communicating from the eaves side to the ridge side is formed between the corrugated roof tile 1b and the base body 1a, and the corrugated roof tile 1b and the base body are ventilated by the third ventilation passage C being aerated. Ventilation to and from 1a is performed.
A ridge cover 3 is installed above the facing roof panel bodies 1. This ridge cover 3 is a roof panel body 1 facing
The ventilation frame 7 is installed between the ventilation frame 7 and the ridge package 8 installed above the ventilation frame 7 so as to cover the ventilation frame 7. The ridge cover 3 communicates with the first ventilation path A in the ridge cover 3. In addition, a second ventilation path B communicating with the outside is provided. A mounting piece 7b is projected from the vertical piece 7a provided at the end of the ventilation frame 7 to the side. By mounting the mounting piece 7b on the fixing member 5, the ventilation frame 7 Are installed between the roof panel bodies 1 facing each other. The vertical piece 7a and the mounting piece 7b are each provided with a ventilation port 9, and the ventilation port 9 forms a part of the second ventilation path B. A rising piece 7c is erected upward from the end of the placing piece 7b.
A baffle plate 10 is provided in the. As shown in FIG. 3, the baffle plate 10 is provided with an uneven portion 11 corresponding to the corrugated shape of the corrugated roof tile 1b at the bottom thereof.
It is provided on the rising piece 7c so as to be aligned with. Here, a slight gap 12 is provided between the baffle plate 10 and the upper surface of the corrugated roof tile 1b so that the ventilation from the ventilation port 9 is not obstructed. The presence of the baffle plate 10 prevents wind and rain from blowing inward and prevents small animals such as sparrows from entering the ridge cover 3. The second ventilation passage B is provided in the ventilation frame 7 through the ventilation port 9 and the gap 12 .
It is formed so as to communicate with the outside from one side . Master beam 13
Support plates 14 are installed at predetermined intervals along the longitudinal direction of the ridge beam 13 on the upper part of the roof panel body 1 and the frame body 1d.
Is mounted on the end portion of the support plate 14 to be connected to the master beam 13. The ridge beam 13 is fireproof coated over the entire length by a coating material 16, and the ridge portion has a fireproof structure.
The frame body 1d that constitutes the roof panel body 1 is provided with through holes 17 that form a part of the first ventilation path A at predetermined intervals, and the hot air in the attic is shown by the arrow C in the figure. It is designed to flow into the ridge cover 3 through the through hole 17.

However, when the temperature of the attic 2 rises, the hot air in the attic 2 rises due to natural convection, and the rising hot air passes through the through hole 17 as shown by the arrow C in the figure, and the first
The air flows from the air passage A into the ridge cover 3, and is exhausted to the outside through the air vents 9 and the gaps 12 that form the second air passage B provided in the ventilation frame 7 forming the ridge cover 3. Further, when the temperature of the roof panel body 1 rises, hot air rises in the third ventilation path C between the corrugated roof tile 1b and the base body 1a forming the roof panel body 1 as shown by an arrow B in the figure. After this hot air flows into the ridge cover 3,
The air is discharged from the ventilation passage B to the outside.

Ventilation between the corrugated tile 1b and the base 1a, which form the attic 2 and the roof panel 1, is efficiently performed together in the ridge by natural convection.
