DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The embodiment of the present invention will be described with reference to the attached drawings. Fig. 1 is a perspective view showing the configuration of one embodiment of the ventilation material 1 according to the present invention. As shown in Fig. 1, the ventilation material 1 is composed of a long frame material 2 having an inverted U-shaped cross section and allowing ventilation on both sides in the width direction, and a similarly long drip edge 3 and a pair of ventilation members 4, 5 that are incorporated into the frame material 2.

[0016] The upper end of one side of the frame material 2 is bent horizontally inward to form the first retaining edge 6, and the upper end of the other side is extended outward by an appropriate length and then folded upward to form the crimping protruding edge 7. The tip of the folded portion is then extended further into the frame material 2 to form the second retaining edge 8. In the example shown in Figure 1, the crimping protruding edge 7 is flat from the second retaining edge 8 to the second retaining edge 8, but the crimping protruding edge 7 may also be bent downward from the middle (see Figure 2).

[0017] A pair of ventilation members 4, 5 are arranged at a distance from each other at both ends in the width direction within the frame material 2, with one ventilation member 4 held down by a first retaining edge 6 and the other ventilation member 5 held down by a second retaining edge 8, with a drainage 3 in between. The drainage 3 is installed so that its bent portion faces diagonally downward. The side surface 9 of the frame material 2 on the side where the protruding edge 7 for crimping is provided may be slightly inclined outward to improve ventilation (see Figure 1).

[0018] The ventilation members 4, 5 have numerous ventilation passages 10 that allow ventilation in the width direction (short length direction), and can be manufactured by a known method, for example, by stacking multiple plastic plates, each having ventilation passages arranged side by side that pass through in the width direction, and then fusing them with a hot wire to make them of a specified width and integrating them together (see Patent No. 2610342, etc.).

[0019] The ventilation material 1 is combined with a pair of upper and lower metal sheets 11, 12 shown in Figs. 3 and 4 to form a ridge ventilation unit A for a gable roof (Fig. 5) or an attic ventilation unit B for the above-water part of a shed roof (Fig. 6). In the upper metal sheet 11, one end of the long flat plate in the width direction is bent downward to form a narrow crimping folded edge 13. As in the example shown in Fig. 2, when the crimping protruding edge 7 is bent downward from the middle part, the crimping folded edge 13 is also bent downward and extended accordingly (Fig. 3(B)). In addition, the end opposite to the side where the crimping protruding edge 7 is formed is bent wide, but when forming the ridge ventilation unit A for a gable roof, it is bent downward to form a ridge wrap 14 (Figs. 3 and 5), and when forming the attic ventilation unit B for a shed roof, it is bent upward to form a fixed edge 17 (Fig. 6).

[0020] The lower metal sheet is a water-repellent metal sheet 12, which is a common configuration for the ridge ventilation unit A of a gable roof and the attic ventilation unit B of a eaves roof. That is, one end of the horizontally long flat plate in the width direction is bent downward to a wide width to form the panel door cover 15, and the other end is bent upward to a narrow width to form the water-repellent 16.

[0021] Figure 5 shows the installation of a ridge ventilation unit A on a gable roof, which is installed on underlayment materials 22 and 23 on a sheathing board 21. Installation is carried out in the following order: Reference numeral 24 denotes a shingle door, 25 a roofing material, 26 a rafter, 27 an exterior wall material, 28 a ventilation furring strip, and 29 a structural plywood.

[0022] 1) The ventilation material 1 is fixed to the drip-proof metal plate 12 by aligning the end of its protruding edge 7 for crimping with the panel door cover 15. 2) Insert the panel door cover 15 between the panel door 24 and the roof material 25, and fix the water drip sheet metal 12 to the base material 23. 3) The upper metal sheet 11 is placed over the base material 22 and the ventilation material 1 and fixed to the base material 22. 4) The protruding crimping edge 7 is crimped by the folded crimping edge 13.

[0023] In the ridge ventilation unit A constructed in this manner, air in the attic that escapes from an opening (not shown) in the sheathing board 21 flows into the ridge ventilation unit A, passes between the upper metal sheet 11 and the drip-water metal sheet 12, passes through the ventilation material 1, and is released into the atmosphere. Outside air flows in the opposite direction, but rain and snow carried in by strong winds are slowed down by the ventilation resistance of the pair of ventilation members 4, 5 as they pass through the ventilation material 1, and drip-water boards 3 and 16 reliably prevent them from entering the room inside.

[0024] FIG. 5 shows the installation state of the attic ventilation unit B for the eaves roof, which is fixed and installed on the base material 23 on the sheathing board 21 in the following installation order. 1) The ventilation material 1 is fixed to the drip-proof metal plate 12 by aligning the end of its protruding edge 7 for crimping with the panel door cover 15. 2) Insert the panel door cover 15 between the panel door 24 and the roof material 25, and fix the water drip sheet metal 12 to the base material 23. 3) The fixed edge 17 of the upper metal sheet 11 is fixed to the pillar 29, and the ventilation furring strip 28 and exterior wall material 27 are attached on top of it, and the horizontal surface is covered with the ventilation material 1. 4) The protruding crimping edge 7 is crimped by the folded crimping edge 13.

[0025] In the attic ventilation unit B of the eaves roof constructed in this manner, the air in the attic on the first floor flows into the attic ventilation unit B, passes between the upper metal sheet 11 and the drip-water sheet 12, passes through the ventilation material 1, and is released into the atmosphere. Outside air flows in the opposite direction, but rain and snow carried in by strong winds are slowed down by the ventilation resistance of the pair of ventilation members 4, 5 as they pass through the ventilation material 1, and drip-water sheets 3 and 16 reliably prevent them from entering the room inside.

[0026] The ventilation material 1, the upper metal sheet 11, and the water-repellent metal sheet 12 are supplied as independent components and assembled at the construction site. Therefore, the upper metal sheet 11 and the water-repellent metal sheet 12, which will be exposed in whole or in part after construction, can be prepared in a variety of colors and patterns, or in a variety of shapes other than the specific shapes mentioned above, so that the contractor can select and combine them as desired. This allows for diversity in the design and allows for a unique finish. [Industrial Applicability]

[0027] The present invention has the above-mentioned configuration, is simple in structure and easy to install, and can be used for both attic ventilation in the ridge part of a gable roof and attic ventilation in the above-water part of a eaves roof. Moreover, it can be finished with a unique character, so it has great industrial applicability. [Explanation of symbols]
