The base member 10B has a hole 31a for the connector 31, a hole 32 for attaching to the apron door 3, and a drainage hole 61.

[0020] Figure 5 shows the wind and rain guide plate of the built-in ventilation component; Figure 5(a) is a perspective view from the eaves side, Figure 5(b) is a perspective view from the top of the roof surface, and Figure 5(c) is a cross-sectional view. The wind and rain guide plate 20 has a width W2 and includes a guide plate upright portion 21 and a guide plate inclined portion 22. The guide plate upright portion 21 is positioned opposite the front ventilation opening 12, and the guide plate inclined portion 22 is positioned closer to the eaves than the guide plate upright portion 21. The lower end of the guide plate upright portion 21 is bent toward the top of the roof surface 2 to form the guide plate upright portion base surface 21t. The lower end of the guide plate inclined portion 22 is bent toward the top of the roof surface 2 to form the guide plate inclined portion base surface 22t. A hole 31b for the connector 31 is formed in the upper base surface 21t of the guide plate. The guide plate's upright section 21 has multiple drainage holes 62 that are longer in the height direction than in the width direction. The lower end of the opening of the drainage holes 62 is at the same height as the base surface 21t of the guide plate's upright section.

[0021] Figure 6 shows the ridge cover member used when installing the built-in ventilation member. Figure 6(a) is a perspective view from the eaves side, Figure 6(b) is a cross-sectional view at a position without a cover opening, and Figure 6(c) is a cross-sectional view at a position with a cover opening. In the structure shown in Figure 1, a ridge cover member 5A for a single-slope roof is used. The ridge cover member 5A for a single-slope roof has a top surface member 51 corresponding to the roof surface 2 of the single-slope roof, a hanging member 52 corresponding to the wall surface, and a front surface member 53 that covers the front surface of the purlin board 4. The upper surface of the purlin board 4 is covered by the top surface member 51. The lower end of the front surface member 53 is bent toward the eaves to form an extended surface 53t of the front surface member. The ridge cover member 5A forms a cover opening 5b by cutting out a portion 5a of the ridge capping of the front material 53 to match the installation position of the built-in ventilation member 1A.

[0022] If the width of the ridge cover member 5A is La and the width of the cover opening 5b is Lb, then in this embodiment, the width La of the ridge cover member 5A should be greater than the sum of the width Lb of the cover opening 5b and the width of the pair of protruding surfaces 13x. However, when using a ridge cover member 5A that is commonly used, the width La of the ridge cover member 5A should be 1.5 times or more, preferably 3 times or more, the width Lb of the cover opening 5b. The width Lb of the cover opening 5b is narrower than the width W1 of the ventilation member body 10, preferably less than or equal to the width W2 of the wind and rain guide plate 20, and is such that it does not block the front ventilation opening 12. In this embodiment, the width Lb of the cover opening 5b and the width W2 of the wind and rain guide plate 20 are the same.

The lower end of one front material 53 is bent toward the eaves to form an extension surface 53t of the one front material, and the lower end of the other front material 53 is bent toward the eaves to form an extension surface 53t of the other front material. The ridge cover member 5B forms one cover opening 5b by cutting out a portion 5a of the ridge capping of one front material 53 to match the installation position of the built-in ventilation member 1A, and forms the other cover opening 5b by cutting out a portion 5a of the ridge capping of the other front material 53 to match the installation position of the built-in ventilation member 1A.

[0030] If the width of the ridge cover member 5B is La, and the widths of one cover opening 5b and the other cover opening 5b are Lb, then in this embodiment, the width La of the ridge cover member 5B should be greater than the sum of the width Lb of one cover opening 5b or the other cover opening 5b and the width of the pair of protruding surfaces 13x. However, when using a ridge cover member 5B that is used in general, the width La of the ridge cover member 5B should be 1.5 times or more, preferably 3 times or more, the width Lb of one cover opening 5b or the other cover opening 5b.

[0039] Figure 22 shows the front ventilation opening forming member of the built-in ventilation member, where Figure 22(a) is a perspective view from the eaves side, Figure 22(b) is a perspective view from the top side of the roof surface, and Figure 22(c) is a cross-sectional view. The front ventilation opening forming member 10A has a width W1 and includes a front plate 13 that forms the front ventilation opening 12. The front panel 13 has multiple front ventilation openings 12 that are wider horizontally than vertically. In addition, extended surfaces 13x are formed on both sides of the front panel 13, which are covered by ridge cover members 5A. The extended surfaces 13x do not have front ventilation openings 12, thus providing excellent waterproofing. The extended surface 13x is formed outward from the width W2 of the wind and rain guide plate 20. As shown in Figures 20 and 21, the wind and rain guide plate 20 is not positioned opposite the extended surface 13x. Furthermore, the extended surface 13x and the ridge cover member 5A are fixed to the side surface of the purlin 4 by the ridge cover member fastener 42.

[0040] The front ventilation opening forming member 10A forms the eaves-side top surface 14. The eaves-side top surface 14 is supported by the front panel 13 and the middle panel 15. The middle panel 15 has multiple middle ventilation openings 16 that are wider horizontally than vertically. The lower end of the front panel 13 is bent towards the eaves to form the front panel base surface 13t, and the lower end of the middle panel 15 is bent towards the top of the roof surface 2 to form the middle panel base surface 15t. A hole 31a for the connector 31 is formed in the front panel base surface 13t. The lower end of the middle ventilation opening 16 is positioned higher than the lower end of the front ventilation opening 12, while the upper end of the front ventilation opening 12 is positioned lower than the upper end of the middle ventilation opening 16. The lower end of the middle ventilation opening 16 is positioned higher than the middle panel base surface 15t, while the lower end of the front ventilation opening 12 is at the same height as the front panel base surface 13t.

[0041] Figure 23 shows the base member of the built-in ventilation component; Figure 23(a) is a perspective view from the eaves side, Figure 23(b) is a perspective view from the top of the roof surface, and Figure 23(c) is a cross-sectional view. The base member 10B has a width W2 and is equipped with a back panel 17 that forms a rear ventilation opening 11. The rear panel 17 has multiple rear ventilation openings 11 that are wider horizontally than vertically. The base member 10B has a base bottom surface 18 that abuts against the apron door 3 and a base side surface 19 that abuts against the crossbar 4. The upper end of the back panel 17 is bent towards the eaves to form the top surface 17s. The lower end of the rear ventilation opening 11 is positioned higher than the lower end of the front ventilation opening 12 and higher than the base bottom surface 18. The base member 10B has a hole 31a for the connector 31, a hole 32 for attaching to the apron door 3, and a drainage hole 61.

[0042] Figure 24 shows the wind and rain guide plate of the built-in ventilation component; Figure 24(a) is a perspective view from the eaves side, Figure 24(b) is a perspective view from the top of the roof surface, and Figure 24(c) is a cross-sectional view. The wind and rain guide plate 20 has a width W2 and includes a guide plate upright portion 21 and a guide plate inclined portion 22. The guide plate upright portion 21 is positioned opposite the front ventilation opening 12, and the guide plate inclined portion 22 is positioned closer to the eaves than the guide plate upright portion 21. The lower end of the guide plate upright portion 21 is bent toward the top of the roof surface 2 to form the guide plate upright portion base surface 21t. The lower end of the guide plate inclined portion 22 is bent toward the top of the roof surface 2 to form the guide plate inclined portion base surface 22t. A hole 31b for the connector 31 is formed in the upper base surface 21t of the guide plate. The guide plate's upright section 21 has multiple drainage holes 62 that are longer in the height direction than in the width direction. The lower end of the opening of the drainage holes 62 is at the same height as the base surface 21t of the guide plate's upright section.

[0043] Figures 25 to 28 show the installation method for the built-in ventilation component. In this embodiment as well, the ridge cover member 5A described in Figure 6 is used, and the following construction is performed after the construction described in Figure 7. Figure 25(a) is a perspective view showing the construction process after the construction process shown in Figure 7, and Figure 25(b) is an enlarged perspective view of the main part of Figure 25(a). As shown in Figure 25, the built-in ventilation member 1A is positioned. Then, the built-in ventilation member 1A is attached to the apron door 3 using the main body fixing device 41. In this way, the built-in ventilation member 1A can be securely fixed by attaching the ventilation member body 10 to the apron flashing 3 and the base material 8 with the body fixing device 41 before it is covered by the ridge cover member 5A.

[0044] Figure 26(a) is a perspective view showing the construction process after the construction process shown in Figure 25, and Figure 26(b) is an enlarged perspective view of the main part of Figure 26(a). As shown in Figure 26, the crossbars 4 are installed by abutting them against both end faces of the base member 10B. Therefore, on the extended surface 13x, the front ventilation opening forming member 10A and the crossbars 4 overlap.

[0045] Figure 27 is a perspective view showing the construction process after the construction process shown in Figure 26. As shown in Figure 27, the ridge cover member 5A, which has a cover opening 5b, covers the built-in ventilation member 1A and the purlins 4 located on both sides of the built-in ventilation member 1A. The ridge cover member 5A has a cover opening 5b formed in advance.

[0046] Figure 28(a) is a perspective view showing the construction process after the construction process shown in Figure 27, and Figure 28(b) is an enlarged perspective view of the main part of Figure 28(a). As shown in Figure 28, the extended surface 13x and the ridge cover member 5A are fixed to the side surface of the purlin 4 by the ridge cover member fastener 42. The ridge cover member fastener 42 fixes the front material 53 to the built-in ventilation member 1A at the position of the extended surface 13x. The ridge cover member fastener 42 is inserted from the eaves side toward the top of the roof surface 2, approximately parallel to the roof surface 2. In this embodiment, the extended surface 13x is brought into contact with the side surface of the purlin board 4, and the extended surface 13x and the ridge cover member 5A are fixed to the side surface of the purlin board 4 by the ridge cover member fixing device 42, thereby ensuring that the built-in ventilation member 1B and the ridge cover member 5A are securely fixed.

[0047] Furthermore, the built-in ventilation component 1B can be installed using the installation method described in Figures 8 to 10, and the built-in ventilation component 1A can also be installed using the installation method described in Figures 25 to 27. Furthermore, the built-in ventilation member 1B can also be installed on a double-slope roof using the ridge cover member 5B shown in Figure 13. Furthermore, even when installing on a double-slope roof as described in Figures 14 to 19, it can also be installed using the installation method described in Figures 25 to 27.

[0048] Further embodiments of the present invention, including built-in ventilation members, will be described below. Figure 29 is a perspective view of the built-in ventilation component. Note that the basic configuration is the same as in Figures 21(b), 22, 23, and 24, and therefore is omitted from the illustration. The built-in ventilation member 1C comprises a ventilation member body 10 that forms a rear ventilation opening 11 on the top side of the roof surface 2 and a front ventilation opening 12 on the eaves side, and a wind and rain guide plate 20 that is positioned at a predetermined distance from the front ventilation opening 12 and faces the front ventilation opening 12. The ventilation member body 10 and the wind and rain guide plate 20 are connected by a connector 31. Rivets are used for the connector 31. The ventilation member body 10 is composed of a front ventilation opening forming member 10A and a base member 10B. The width W1 of the front ventilation opening forming member 10A is wider than the width W2 of the wind and rain guide plate 20, but the width W2 of the base member 10B is the same as the width W2 of the wind and rain guide plate 20. In this embodiment, a portion 13y of the front panel 13 is provided in which the front ventilation opening 12 is not formed, and the wind and rain guide plate 20 is not provided at a position opposite to this portion 13y in which the front ventilation opening 12 is not formed. In this way, by not providing the wind and rain guide plate 20 and providing the portion 13y in which the front ventilation opening 12 is not formed, the ridge cover member 5C can be fixed to the ventilation member body 10. If the width W1 of the ventilation member body 10 is larger than a predetermined dimension, it is preferable to provide a portion 13y in the middle of the width W1 of the ventilation member body 10 in which the front ventilation opening 12 is not formed, as shown in this embodiment, and to fix the ridge cover member 5C to the ventilation member body 10.

[0049] Figure 30 is a perspective view showing the installation state of the built-in ventilation member on the roof surface according to this embodiment, with Figure 30(a) showing the state with the ridge cover separated and Figure 30(b) showing the state with the ridge cover attached. In this embodiment, the built-in ventilation member 1C is installed on the top of a sloped roof surface 2 with a base material 8 having a predetermined height, an apron flashing 3 is installed on the upper surface of the base material 8, and the built-in ventilation member 1C is positioned between a pair of purlin boards 4 installed on the apron flashing 3. The built-in ventilation member 1C is then covered on its upper surface by a ridge cover member 5C that covers the upper and side surfaces of the pair of purlin boards 4, thereby forming a ridge ventilation air passage. The built-in ventilation member 1C is attached to the apron flashing 3 by a main body fixing device 41 (see Figure 31). The extended surface 13x and the ridge cover member 5C are fixed to the side surface of the purlin board 4 by a ridge cover member fixing device 42. The portion 13y that does not form a front ventilation opening 12 and the ridge cover member 5C are fixed by a ridge cover member fixing device 42. The roof sheathing material 6 has a roof decking opening 7 installed. The ridge cover member 5A forms a cover opening 5b by cutting out a part of the ridge cover 5a to match the installation position of the built-in ventilation member 1C.

[0050] Figures 31 to 34 show the installation method for the built-in ventilation component. In this embodiment as well, the following construction is performed after the construction described in Figure 7. Figure 31(a) is a perspective view showing the construction process after the construction process shown in Figure 7, and Figure 31(b) is an enlarged perspective view of the main part of Figure 31(a). As shown in Figure 31, the built-in ventilation member 1C is positioned. Then, the built-in ventilation member 1C is attached to the apron door 3 using the main body fixing device 41. In this way, the built-in ventilation member 1C can be securely fixed by attaching the ventilation member body 10 to the apron flashing 3 and the base material 8 with the body fixing device 41 before it is covered by the ridge cover member 5C.

[0051] Figure 32(a) is a perspective view showing the construction process after the construction process shown in Figure 31, and Figure 31(b) is an enlarged perspective view of the main part of Figure 31(a). As shown in Figure 31, the crossbars 4 are installed by bringing them into contact with both end faces of the base member 10B. Therefore, on the extended surface 13x, the front ventilation opening forming member 10A and the crossbars 4 overlap.

[0052] Figure 33 is a perspective view showing the construction process after the construction process shown in Figure 32. As shown in Figure 33, the ridge cover member 5C, which has a cover opening 5b, covers the built-in ventilation member 1C and the purlins 4 located on both sides of the built-in ventilation member 1C. The ridge cover member 5C has a cover opening 5b formed in advance.

[0053] Figure 34(a) is a perspective view showing the construction process after the construction process shown in Figure 33, and Figure 34(b) is an enlarged perspective view of the main part of Figure 34(a). As shown in Figure 34, the extended surface 13x and the ridge cover member 5C are fixed to the side surface of the purlin 4 by the ridge cover member fastener 42. The portion 13y that does not form the front ventilation opening 12 and the ridge cover member 5C are also fixed by the ridge cover member fastener 42. The ridge cover member fastener 42 fixes the front material 53 to the built-in ventilation member 1C at the position of the extended surface 13x and the portion 13y that does not form the front ventilation opening 12. The ridge cover member fastener 42 is inserted from the eaves side toward the top of the roof surface 2, approximately parallel to the roof surface 2. For the ridge cover member fasteners 42 used in the portion 13y where the front ventilation opening 12 is not formed, screws designed to fasten thin sheet metal pieces together are preferable. In this embodiment, the extended surface 13x is brought into contact with the side surface of the purlin board 4, and the extended surface 13x and the ridge cover member 5A are fixed to the side surface of the purlin board 4 by the ridge cover member fixing device 42, thereby ensuring that the built-in ventilation member 1C and the ridge cover member 5C are securely fixed. Furthermore, as shown in this embodiment, a portion 13y is provided in the middle of the width W1 of the ventilation member body 10 in which the front ventilation opening 12 is not formed, and the ridge cover member 5C is fixed to the ventilation member body 10, so that the ridge cover member 5C can be securely fixed to the built-in ventilation member 1C.

[0054] The built-in ventilation component 1C can be installed using the construction method described in Figures 8 to 10. Furthermore, the built-in ventilation component 1C can also be installed on a double-slope roof.

[0055] As described above, with the built-in ventilation members 1A, 1B, and 1C according to this embodiment, the built-in ventilation members 1A, 1B, and 1C can be installed even by cutting out a part 5a of the ridge cover members 5A, 5B, and 5C that cover the upper and side surfaces of the purlin board 4. The wind and rain guide board 20 can be fixed by the extended surface 13x that does not face it, and the extended surface 13x is covered by the ridge cover members 5A, 5B, and 5C, resulting in excellent waterproofing and aesthetics. Furthermore, the installation method for the built-in ventilation members 1A, 1B, and 1C according to this embodiment involves placing the built-in ventilation members 1A, 1B, and 1C between a pair of purlin boards 4 installed on the apron flashing 3, attaching the built-in ventilation members 1A, 1B, and 1C to the apron flashing 3, forming a cover opening 5b by cutting out the ridge cover members 5A, 5B, and 5C, and covering the built-in ventilation members 1A, 1B, and 1C, as well as the purlin boards 4 located on both sides thereof, with the ridge cover members 5A, 5B, and 5C that have formed the cover opening 5b. The built-in ventilation members 1A, 1B, and 1C can be installed by cutting out a part 5a of the ridge cover members 5A, 5B, and 5C that cover the top and sides of the purlin boards 4, and the extended surface 13x is covered by the ridge cover members 5A, 5B, and 5C, resulting in excellent waterproofing and aesthetics.
