Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a ridge cover material that is installed on the ridge of the roof of a building and is suitably used for ventilation in a small attic.

[Prior Art] In recent years, most of the buildings constructed have built-in systems that allow humid air from indoors to flow out of the room through the walls.
It has a structure with a ventilation layer between the outer and inner walls and a perforated plate under the eaves. Air flowing into the building through the ventilation layer and the perforated plate under the eaves flows out through the attic.

For this reason, attics have traditionally been provided with ventilation holes or ventilation devices of various shapes.

As a conventional ridge ventilation system, for example, Utility Application No. 58-9166
A device No. 1 (published as Utility Model Application Publication No. 196625/1983) has been proposed. As shown in FIG.
In a roof ventilation system consisting of a crown body 4 with a ventilation hole 3 provided at the bottom, a structure in which a large number of parallel needle-shaped bodies 6 are densely provided in a ventilation path 5 between the ventilation holes 2 and 3 is used. It has been stated. That is, the air that exits the vent 2 from the small attic passes through the vent 5 between the needles 6 and is discharged to the outside from the vent 3. On the other hand, in rainy weather, the air flows from the vent 3 to the vent 5 due to the wind. The rainwater that has entered inside hits the needle-like bodies 6, adheres to the needle-like bodies 6, falls, and is discharged along the roof surface 1.

Further, as another conventional example, Japanese Patent Laid-Open No. 165754/1983 is known. This is a cover that is fixed to the ridge or hip plank of a roof structure and forms a complete part over the top of the ridge or hip, as well as a cover placed between it and the roof surface. comprising a flexible sealing strip, and
A device is disclosed in which the sealing strip is in close contact with the roof surface with its longitudinal edge directed towards the roof surface.

[Problems to be Solved by the Invention] However, since the ventilation device of Utility Model Application No. 58-91661 is installed on an obliquely formed roof surface, it may be difficult to attach and fix the device. On the other hand,
The technique disclosed in Japanese Patent No. 9-165754 has the drawback that the structure of the ventilation system is too complicated.

An object of the present invention is to provide a ridge cover material for these roof ventilation structures that is suitable for being installed on the ridge of a roof, which has a ventilation opening, is extremely easy to install, and has a simple structure. shall be.

"Means for Solving the Problem" According to the present invention, the purpose is to provide a ridge cover material that is attached to the ridge of a roof and for ventilation from indoors to outdoors, and the ridge cover material is It is composed of two plate-shaped ridge ventilation members extending in the direction, and its cross section has an approximately inverted 7-shape. Each ridge ventilation member is tapered from the top to the bottom, and each ridge ventilation This can be achieved with a ridge cover material characterized in that the member is provided with a large number of communicating ventilation holes.

[Function] As shown in FIG. 1, the ridge cover material of the present invention is attached by covering the ridge of the roof from above.

Moist air that permeates through the walls passes through the ventilation layer between the outer and inner walls, the perforated plate under the eaves, and then passes through the attic to the ridge cover installed in the ridge, and then passes through the ventilation holes installed in the ridge cover. It passes through the interior and is discharged outside.

On the other hand, even in times of strong winds accompanied by rain, rain will not enter from outside through the ventilation holes in the ridge cover material and fall as water droplets on the attic.

[Example] The present invention will be explained below with reference to illustrated examples, but the present invention is not limited to these examples. Fig. 1 schematically shows a roof structure using the ridge cover material according to the present invention. This is a schematic cross-sectional view showing a roof surface of a ridge cover material 10, which is composed of a pair (two) plate-shaped ridge ventilation members 10a and 10b and has an almost inverted V-shaped cross-sectional shape. It is installed so as to cover the ridge vents 12 of No. 11 from above.

Figure 2 shows one ridge ventilation member 10a that constitutes the ridge cover material.
FIG. The ridge ventilation member 10a is tapered from the upper surface 13 toward the lower surface 14, that is, formed in a tapered shape. The ridge ventilation member 10a is provided with a large number of ventilation holes 15 that communicate with each other in the lateral direction, and indoor air is exhausted to the outside through the ridge ventilation hole 12 and the ventilation hole 15 of the ridge ventilation member 10a. Ru.

The ridge covering material consists of two ridge ventilation members 10a and 10b, that is, a pair, and the upper surface L3a of the ridge ventilation member 10a and the upper surface 14b of the ridge ventilation member 10b are joined as shown in FIG. It is composed of

An example of a method for manufacturing this ridge cover material will be explained based on FIGS. 4 and 5.

A predetermined number of plastic plates 20 each having a cross-sectional shape of a vent hole, such as rectangular or wavy, are stacked one on top of the other and fixed by heat fusion using, for example, a heating rod 21 to produce a plate laminate 22. Next, the obtained plate laminate 22 is diagonally cut using a hot wire cutter (not shown) or the like to produce a ridge ventilation member 23. Note that the ridge ventilation member 23 obtained at this time is given rigidity by heat fusion. Next, one side of the ridge ventilation member 23 is inverted, and as shown in FIG. A ridge cover material having an inverted V shape is produced.

Hereinafter, a test example using the ridge cover material of the present invention will be explained.

(Test Example) Fig. 6 shows a roof model wind tunnel test equipment, and as shown in Fig. 7, the dimensions of one ridge ventilation member are L = 225 mm, M = 45mm,
N = 100 mm, P = 45 mm, Q
= 80 mm, and the ridge cover material of the present invention having a length in the ridge direction of 1,300 mm was installed. On the other hand, an air current is generated by four axial flow blowers 25, rectified by a rectifying section 26, further contracted, and then air current is generated from an air outlet 27 with a cross section of 1.3 m Xl, 3 I at a wind speed of 12 m/sec. I burst out laughing.

Further, the test was conducted under the condition that water with a rainfall amount of 400+nn/I was spouted from the nozzle 28 having a large number of small holes.

The wind direction relative to the roof was varied in three ways: O', 30°, and 45°. About 3 for one pattern
Wind and rain were applied for 0 minutes, and the presence or absence of rain intrusion was examined from the small attic.

As a result, which pattern (wind direction θ-0°30', 4
5°), no penetration of rain through the ridge covering material of the present invention was observed, indicating that the ridge covering material of the present invention had excellent performance.

[Effects of the Invention] As explained above, the ridge cover material of the present invention is composed of two plate-shaped ridge ventilation members extending in the ridge direction, and is configured so that the cross-sectional shape is approximately an inverted 7-shape. The ventilation members are tapered from the top to the bottom, and each ridge ventilation member has a large number of communicating ventilation holes, providing excellent rainproof performance against strong winds and rain. Furthermore, it is lightweight, easy to handle even when working at heights, and requires no man-hours for construction.
