Description

[Technical Field]

[0001] The present invention relates to a ventilation material and a ventilation unit using the same, and more specifically to a ventilation material and a ventilation unit using the same for attic ventilation in the ridge part of a shed roof or gable roof, and attic ventilation in the above-water part of a eaves roof, while preventing the intrusion of rain and snow. [Background technology]

[0002] Prior documents disclosing ventilation units that provide attic ventilation in the ridge portion of a gable roof include Patent No. 6004573 and Patent No. 6192203, and prior documents disclosing ventilation units that provide attic ventilation in the above-water portion of a shed roof include Patent No. 2022-89766 and Patent No. 2016-125192.

[0003] The ventilation units disclosed in these prior art documents are all designed specifically for ventilation of the ridge of a shed roof or the attic space above the water surface of a shed roof, and are not intended to be used for other purposes. In addition, because they are supplied as finished products, their designs are uniform and color and shape cannot be selected.

[0004] In light of these problems with conventional technology, the applicant of the present application has previously proposed a ventilation material and a ventilation unit using the same that 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, allows selection of the color and shape of the part, and has a simple structure and is easy to install (Patent Application No. 2022-188406). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6004573 [Patent Document 2] Patent No. 6192203 [Patent Document 3] Japanese Patent Publication No. 2022-89766 [Patent Document 4] Japanese Patent Application Laid-Open No. 2016-125192 [Patent Document 5] Patent application No. 2022-188406 Summary of the Invention [Problem to be solved by the invention]

[0006] The ventilation material proposed above consists of a long frame material with an inverted U-shaped cross section, with both widthwise sides made breathable, and a long drip edge and a pair of ventilation members incorporated into the frame material, with the upper end of one side of the frame material bent horizontally inward to form a first retaining edge, the upper end of the other side extending outward and folded upward to form a protruding edge for crimping, the tip of the folded portion extending further into the frame material to form a second retaining edge, the pair of ventilation members being arranged at intervals at both ends of the interior widthwise of the frame material, with one of the ventilation members being retained by the first retaining edge and the other ventilation member being retained by the second retaining edge, with the drip edge sandwiched between them.

[0007] In the case of this ventilation material, the ventilation material and the drain are separate components, so not only is it time-consuming to mold them separately and then insert and secure the drain between the top surface of the ventilation material and the second retaining edge, but the ventilation material is also long (for example, 80 mm wide and 910 mm long), and both sides are opened widely to ensure breathability, so it became necessary to increase its rigidity.

[0008] The present invention has been made to meet this need, and its objective is to provide a ventilation material and a ventilation unit using the same that is easy to manufacture and install, can be used for attic ventilation in the ridge parts of shed roofs and gable roofs, and for attic ventilation in the above-water parts of eaves roofs, and has increased rigidity so that there is no risk of it bending or deforming due to heat after installation. [Means for solving the problem]

[0009] The invention described in claim 1 for solving the above problem comprises a long frame material having an inverted U-shaped cross section with a bottom surface and both side surfaces, and a ventilation member attached to the inside of each of the both side surfaces, An upper end of one of the two side surfaces is bent inward and extended to form a first cover surface that covers the entire or part of the upper surface of one of the ventilation members, The upper end of the other of the two side surfaces is bent outward and extended, and the outwardly extended end is folded back upward to form a second cover surface that extends beyond the other ventilation member, A downwardly inclined drip edge is provided on the inner end of the second cover surface, This ventilation material is characterized in that a reinforcing frame rising from the bottom surface is formed at the lower edge of one or both of the ventilation openings extending in the longitudinal direction formed on both side surfaces.

[0010] In one embodiment, the reinforcing frame is provided with drain holes.

[0011] In one embodiment, a portion of the second cover surface that is outer than the other ventilation material is inclined downward, and in another embodiment, a front end portion of the second cover surface that is outer than the other ventilation material is bent downward. Also, in one embodiment, downward protrusions are formed on the second cover surface at appropriate intervals.

[0012] The invention described in claim 5 to solve the above problem is a ventilation unit for ridge ventilation that is formed by combining the ventilation material described in any one of claims 1 to 4 with an upper metal plate and a lower metal plate, The upper metal sheet has a crimping fold bent downward at one end in the width direction and a ridge wrap bent downward at the other end, and the lower metal sheet has a face door cover bent downward at one end in the width direction and a drip edge bent upward at the other end, making this a ventilation unit.

[0013] The invention described in claim 9 to solve the above problem is a ventilation unit for a roof comprising the ventilation material according to any one of claims 1 to 4, an upper metal plate and a lower metal plate, The upper metal sheet has a crimping fold bent downward at one end in the width direction and a fixed fold bent upward at the other end, and the lower metal sheet has a face door cover bent downward at one end in the width direction and a drip tray bent upward at the other end, making this a ventilation unit.

[0014] In one embodiment, a plurality of upper and / or lower metal sheets with different designs including colors are prepared, and can be selected at the time of construction. In another embodiment, the end of the upper metal sheet on the side where the crimping fold is formed is bent at an acute angle or a right angle. [Effects of the Invention]

[0015] Because the ventilation material and ventilation unit of the present invention have the above-mentioned configuration, they are easy to manufacture and install, have high rigidity, and are not likely to bend or deform due to heat after installation.They can also be used for attic ventilation in the ridge parts of shed roofs and gable roofs, and for attic ventilation in the above-water parts of eaves roofs.

DETAILED DESCRIPTION OF THE INVENTION

[0017] An embodiment of the present invention will be described with reference to the accompanying drawings. Fig. 1 is a perspective view of the essential parts showing the configuration of one embodiment of a ventilation material 1 according to the present invention. As shown there, the ventilation material 1 comprises a long frame member 2 having a bottom surface 3 and both side surfaces 4, 5, and also long ventilation members 6, 7 attached to the inside of each of the side surfaces 4, 5. The ventilation material 1 is formed to be long, for example, 80 mm wide and 910 mm long. The bottom surfaces of the ventilation members 6, 7 are fixed to the bottom surface 3 of the frame member 2 by adhesive or the like.

[0018] The upper end of one side surface 4 of the frame material 2 is bent inward and extended to form a first cover surface 8 that covers all or part of the top surface of one ventilation member 6, and the upper end of the other side surface 5 is bent outward and extended, with the extended end folded upward and overlapping, and its leading edge extending beyond the other ventilation member 7 to form a second cover surface 9 that covers the top surface of the ventilation member 7. The inward extending end of the second cover surface 9 is then bent diagonally downward and extended to form a drip edge 10. The ventilation material 1 is formed to be long, for example, 80 mm wide and 910 mm long. Because the frame material 2 has this shape, the entire frame material 2 can be manufactured simply by bending a single sheet of plate material.

[0019] The ventilation members 6, 7 have a large number of ventilation paths 12 that allow ventilation in the width direction (short length direction), and can be manufactured by a known method, for example, by stacking a large number of plastic plates with ventilation paths that pass through in the width direction side by side, fusing them with a hot wire to form a predetermined width and integrating them (see Patent No. 2610342, etc.).

[0020] In order to ensure sufficient ventilation in the width direction of the ventilation members 6, 7, large ventilation openings 13 are formed on both side surfaces 4, 5 of the ventilation material 1. In order to ensure sufficient ventilation, the ventilation openings 13 are preferably large enough to open from the top to the bottom of the side surfaces 4, 5. In the case of the ventilating material 1 according to the present invention, a horizontal series of reinforcing frames 14 are formed at the bottom edge of the ventilation openings 13 on at least one of the side surfaces 4, 5, rising from the bottom surface 3 within a range that does not impede ventilation. Drainage holes 15 are drilled in the reinforcing frames 14 as appropriate (see FIG. 2).

[0021] Typically, the ventilation openings 13 are not continuous along the length of the sides 4 and 5, but are divided into multiple pieces, and vertical frames 16 are placed between each ventilation opening 13 to ensure rigidity in the length direction (see Figure 2), but by providing a reinforcing frame 14, even greater rigidity can be ensured.

[0022] In order to improve breathability, it is preferable that one or both of the side surfaces 4, 5 be slightly inclined outward to separate the side surfaces 4, 5 from the opening end surfaces of the ventilation members 6, 7. In the example shown in FIG. 1 , one side surface 4 is inclined outward to separate the upper part of the side surface 4 from the opening end surface of the ventilation member 6, and the other side surface 5 is inclined inward to separate the lower part of the side surface 5 from the opening end surface of the ventilation member 7.

[0023] Typically, a packing 17 is fixed to the reverse surface of the end portion of the side surface 4 of the bottom surface 3. Furthermore, if necessary, downward hemispherical protrusions 18 are formed on the second cover surface 9 at appropriate intervals (for example, at the center positions of the ventilation openings 13). These protrusions 18 serve to hold down the ventilation member 7.

[0024] The ventilation material 1 is combined with a pair of upper and lower mounting metal sheets 21, 22 to form a ridge ventilation unit A for a gable roof (Fig. 6) or an attic ventilation unit B for the above-water portion of a eaves roof (Fig. 7). When forming the ridge ventilation unit A, the upper metal sheet 21 has a crimping fold 23 bent downward at one widthwise end and a ridge wrap 24 bent downward at the other widthwise end (see Fig. 3). The corresponding lower metal sheet 22 has a panel door cover 25 bent downward at one widthwise end and a drip edge 26 bent upward at the other widthwise end (see Fig. 4).

[0025] Furthermore, when constructing the attic ventilation unit B for the eaves roof, the upper metal sheet 21 has a crimping fold 23 bent downward at one end in the width direction and a fixed edge 27 bent upward at the other end (see Figure 7), and the lower metal sheet 22, as in the case of the ridge ventilation unit A, has a face door cover 25 bent downward at one end in the width direction and a drip edge 26 bent upward at the other end.

[0026] The second cover surface 9 is often made flat as a whole (Fig. 1, Fig. 5(A), (D)), but the folded-back portion 11, which is the portion outside the ventilation member 7, may be inclined downward (Fig. 5(B), (E)), or the end may be bent downward (Fig. 5C), (F)). Also, the open end surfaces of the ventilation members 6, 7 may be inclined (Fig. 5(D), (E), (F)).

[0027] When the entire second cover surface 9 is to be a flat surface, the end of the folded portion 11 is crimped with the crimping fold 23 (FIGS. 5(A) and 5(D)). However, when the folded portion 11 is to be inclined downward, the crimping work can be eliminated by using an upper metal plate 21 in which the extended end is bent at an acute angle to form a hooking surface 23a (FIGS. 5(B) and 5(E)). That is, in this case, it is sufficient to simply hook the hooking surface 23a onto the folded portion 11 of the second cover surface 9. Furthermore, when the end of the folded portion 11 is to be bent vertically downward, the upper metal plate 21 is used in which the end forming the crimping fold 23 is bent to match the bend of the second cover surface 9, and the end of the folded portion 11 is crimped with the crimping fold 23 (FIGS. 5(C) and 5(F)).

[0028] Of the above embodiments, those shown in Figures 5(B), (E), (C), and (F) have a higher degree of closure of the ventilation openings 13 on the side surface 5 than those shown in Figures 5(A) and (D), and therefore have correspondingly improved waterproof and windproof performance.

[0029] Figure 6 shows the installation of a ridge ventilation unit A on a gable roof, which is installed on underlayment materials 32 and 33 on a sheathing board 31. In this case, installation is carried out in the following order: 34 denotes the shutter, 35 the roof material, 36 the rafters, 37 the exterior wall material, 38 the ventilation furring strip, and 39 the structural plywood.

[0030] 1) The ventilation material 1 is fixed to the lower metal plate 22 by aligning the end of its folded portion 11 with the face door cover 25. 2) Insert the panel door cover 25 between the panel door 34 and the roof material 35, and fix the lower metal sheet 22 to the base material 33. 3) The upper metal plate 21 is placed over the base material 32 and the ventilation material 1 and fixed to the base material 32. 4) The folded portion 11 is crimped by the crimping folding edge 23.

[0031] In the ridge ventilation unit A constructed in this manner, the air in the attic space that escapes from the opening (not shown) in the sheathing board 31 flows into the ridge ventilation unit A, passes between the upper metal sheet 21 and the lower metal sheet 22, passes through the ventilation material 1, and is released into the atmosphere. Outside air flows in the opposite direction, but as rain and snow carried in by strong winds pass through the ventilation material 1, they are slowed down by the ventilation resistance of the pair of ventilation members 6, 7, and are reliably prevented from entering the room by the drip edge 10 and the drip edge 26 of the lower metal sheet 22.

[0032] FIG. 7 shows the installation state of the attic ventilation unit B for the eaves roof, which is fixed and installed on the base material 33 on the sheathing board 31 in the following installation order. 1) The ventilation material 1 is fixed to the lower metal plate 22 by aligning the end of its folded portion 11 with the face door cover 25. 2) Insert the panel door cover 25 between the panel door 34 and the roof material 35, and fix the lower metal sheet 22 to the base material 33. 3) The fixed edge 27 of the upper metal plate 21 is fixed to the pillar 39, and the ventilation furring strip 38 and exterior wall material 37 are nailed onto it, and the horizontal surface is covered with the ventilation material 1. 4) The folded portion 11 is crimped by the crimping folding edge 23.

[0033] In the attic ventilation unit B for 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 21 and the lower metal sheet 22, passes through the ventilation material 1, and is released into the atmosphere. Outside air flows in the opposite direction, but when rain and snow carried in by strong winds pass through the ventilation material 1, they are slowed down by the ventilation resistance of the pair of ventilation members 6, 7, and are reliably prevented from entering the room by the water drips 10 and 26.

[0034] Furthermore, although not shown, the ventilation unit according to the present invention can also be used for attic ventilation at the ridge of a gable roof. In this case, two ventilation units are arranged facing each other.

[0035] The ventilation material 1, upper metal sheet 21, and lower metal sheet 22 are supplied as independent components and assembled at the construction site. Therefore, the upper metal sheet 21 and lower metal sheet 22, 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 freely select and combine them for use. This allows for diversity in design and a unique finish. [Industrial Applicability]

[0036] Because the ventilation material and ventilation unit of the present invention have the above-mentioned configuration, they are easy to manufacture and install, have high rigidity, and are not likely to bend or deform due to heat after installation.They can also be used for attic ventilation in the ridge part of a gable roof and for attic ventilation in the above-water part of a eaves roof, and therefore have great industrial applicability.
