Description

TECHNICAL FIELD The present invention relates to a ventilation parting member, and more specifically, to a parting member having ventilation, which is installed mainly in the eaves and verandas of ordinary houses.

In the summer, the exterior and roof materials of houses are exposed to sunlight and become quite hot, and the temperature in the attic often exceeds 65 degrees. Therefore, in order to maintain a comfortable thermal environment indoors and ensure coolness, especially in the summer, it is necessary to ventilate not only the room but also the attic. Furthermore, by promoting ventilation in the attic and drying the attic, the durability of the attic can be increased. Ridge ventilation or eave ventilation is generally used as a method for attic ventilation, and various ventilation devices have been proposed and put into practical use for this purpose.

For example, Japanese Patent Laid-Open No. 2017-95996 filed by the applicant of the present invention discloses a resin ventilation member in which a large number of ventilation passages extending from one sloped opening end surface 42 to the other opening end surface 43 are arranged in a row in all directions. 41, and a metal cover material 44 that sandwiches the ventilation member 41, and the cover material 44 includes an upper support surface 45, a vertical closing surface 46, a lower support surface 47, and a vertical fixing surface 48, A ventilation member is disclosed in which a ventilation space 49 is secured between the vertical closing surface 46 and the sloped open end surface 42 of the ventilation member 41, and a ventilation opening 50 is formed in the lower support surface 47 (see FIG. 8). ).

In the case of the ventilation member configured as described above, since the opening end surface 42 of the ventilation member 41 is formed on a slope so as to cover the ventilation opening 50, rain and snow blown in from the ventilation opening 50 are immediately transferred to the ventilation member 41 from the ventilation opening 50. There is a risk that the air may enter the ventilation path (see the arrow in Figure 8) and enter the indoor side.Also, since the open end surface 42 of the ventilation member 41 is close to the ventilation opening 50 and there is no space between them, the ventilation There is a problem of poor sex. Furthermore, in the case of the ventilation member with this configuration, the vertical fixing surface 48 is installed by nailing and fixing it to the rafters or eave girder via the rim, before the external wall material is nailed and fixed to the rim. There are restrictions on construction.

JP2017-95996

As mentioned above, in the case of the above-mentioned ventilation member, since the ventilation opening into which rain and snow may blow is close to the opening end face of the ventilation member, the rain and snow blown in from the ventilation opening enters the ventilation path of the ventilation member. There is a risk that it may enter the interior of the room, there is a problem with ventilation, and there are also restrictions on installation.

The present invention has been made in view of the above problems, and has a simple structure and excellent ventilation, and rain and snow blown in from the ventilation openings are difficult to enter into the ventilation passages of the ventilation member, so it can enter the indoor side. It is an object of the present invention to provide a ventilation parting member that is free from danger and easy to install.

The invention according to claim 1 for solving the above problem includes: an elongated back plate; a top plate extending in the horizontal width direction from an upper end of the back plate; and a top plate extending in the horizontal width direction from an intermediate portion of the back plate. It has an intermediate plate and a lower plate extending in the horizontal width direction from the lower end of the back plate, and the lower plate has a number of cut-and-raised openings arranged in parallel, and draining materials are arranged along the cut-and-raised opening rows. Further, a resin ventilation member having a large number of ventilation passages extending from one open end face to the other open end face arranged in a row in a row is disposed between the intermediate plate and the top end of the bottom plate, The member is a ventilation parting member characterized in that the inner opening end face where the ventilation passage opens is arranged so as to be spaced apart from the inclined surface of the draining member.

In one embodiment, the width of the intermediate plate is longer than the upper plate and shorter than the lower plate. Further, the intermediate plate is inclined downward toward the tip in the width direction.

In one embodiment, the back plate, top plate, intermediate plate, and bottom plate are formed by bending a single steel plate.

The present invention is as described above, and has a simple configuration and can be easily installed at the end of a roofing board, and is arranged so that the inward opening end face where the ventilation path of the ventilation member opens is separated from the slope of the draining material.

EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated based on an accompanying drawing. The ventilation parting member A according to the present invention includes an elongated back plate 1, a top plate 2 extending from the upper end of the back plate 1 in the horizontal width direction, and a length extending from the middle part of the back plate 1 than the top plate 2 in the horizontal width direction. It has an intermediate plate 3 that extends from the lower end of the back plate 1 and a lower plate 4 that extends in the horizontal width direction longer than the intermediate plate 3. Draining materials 6 are arranged along five rows of openings, and a ventilation member 7 is further arranged between the tips of the intermediate plate 3 and the bottom plate 4.

It is preferable that the width of the intermediate plate 3 is longer than the width of the upper plate 2, and that it is sloped slightly downward toward the tip. This is to enable the shedding board to be smoothly inserted between the top board 2 and the intermediate board 3, as will be described later. Further, the width of the intermediate plate 3 is made to be slightly shorter than the width of the bottom plate 4. This is to facilitate installation of the ventilation member 7 between the tips of the intermediate plate 3 and the bottom plate 4. The back plate 1, the upper plate 2, the intermediate plate 3, and the lower plate 4 can be formed by bending a single steel plate (for example, a galvalume steel plate (registered trademark)). In that case, the upper half of the back plate 1 and the top plate 2 are in a two-layered state (see FIGS. 1 and 2).

The draining material 6 is formed by bending one end of a flat plate upward, and is fixed to the lower plate 4 with its sloped surface 6a facing the cut and raised opening 5. The cut and raised opening 5 is formed by pushing up the middle part of the two cut lines.

The ventilation member 7 can be manufactured by a known method in which a predetermined number of plastic plates each having a large number of parallel ventilation passages 8 extending from one end to the other are stacked and both ends are cut by a heat cutter. When this method is used, the cut ends of the upper and lower ventilation passages 4 are welded to each other as a result of fusing, so that a laminate in which the upper and lower plastic plates are integrated is formed. Although the cross-sectional shape of the ventilation passage 8 formed by fusing in this manner is not a neat square as shown in FIG. 1, it is rather effective in preventing rain and wind from blowing in.

The ventilation member 7 is fixed on the draining material 6 fixed to the bottom plate 4, with its ventilation path 8 oriented in the width direction of the ventilation partition member A to allow ventilation. At this time, the ventilation member 7 is arranged so that the inner end face where the ventilation path 8 opens is sufficiently separated from the slope 6a of the draining member 6, so that a wide space 9 is created there.

A part of the rain and snow blowing in from the cut-up opening 5 hits the slope 6a of the draining material 6 and is bounced back, and part of it falls over the slope 6a of the draining material 6 and falls on the draining material 6, where it accumulates temporarily. However, when the space 9 is formed as described above, the wind blowing in from the cut-up opening 5 hits the back surface of the intermediate plate 3 and swirls around the space 9, as shown by the arrow in FIG. It flows in. The rain and snow that has fallen and accumulated on the draining material 6 is thus blown away by the vortex airflow generated in the space 9 and falls from the cut-up opening 5, so that it enters the ventilation path 8 of the ventilation member 7. Never.

The ventilation parting member A has, for example, a length of 1820 mm and a width of 50 mm, but several pieces may be joined to make it longer. In that case, a joint 10 having a shape that covers from the upper surface plate 2 to the lower surface plate 4 is placed over the joint portion (FIG. 3(A)). Furthermore, end caps 11 of corresponding shapes are placed on both ends (FIG. 3(B)).

The ventilation parting member A according to the present invention can be installed at various locations in a general house. FIG. 4 is a diagram showing how the ventilation parting member A is installed in the verge. In the verge, roofing boards 22 are nailed onto girders 21, roofing material 23 is constructed on top of the girder 21 via asphalt roofing, and plywood 30, a rim 24, and exterior wall material 25 are placed on the outside of the girder 21. The space between each furrow 24 serves as a ventilation layer 26. Although other configurations such as attaching a moisture-permeable/waterproof sheet are included, explanations thereof will be omitted.

The ventilation parting member A is constructed by fitting the end of the shedding board 22 between the upper surface board 2 and the intermediate board 3, and inserting the part below the intermediate board 3 between the shedding board 22 and the exterior wall material 25. Attach it to the end of 22 and secure it with nails, etc. Then, an arabesque 27 is installed vertically so as to hide the back plate 1 of the ventilation parting member A. Further, the gap between the bottom plate 4 and the outer wall material 25 is filled with a sealing material 28 and sealed.

In the above installation situation, the air rising inside the ventilation layer 26 and escaping from the upper end thereof flows into each ventilation path 8 from the open end surface of the ventilation member 7 of the ventilation partition member A, passes through the ventilation path 8, and then returns to the opposite side. It flows out from the side opening end face, passes through the cut and raised opening 5, and is discharged into the atmosphere.

On the other hand, depending on the situation, rain and snow may enter through the cut-up opening 5 along with the wind, but in that case, the slope 6a of the draining material 6 functions as a baffle plate, so that their entry is suppressed as much as possible. In addition, rain and snow that enters over the slope 6a of the draining material 6 and accumulates on the draining material 6 are blown away by the vortex airflow generated in the space 9 as described above, so that the rain and snow enter the ventilation path 8 of the ventilation member 7. It will not enter the room and infiltrate indoors. In addition, by installing the ventilation parting member A as described above, the end of the field board 22 is hidden within the ventilation parting member A made of a steel plate, so that the fire prevention performance in that part is enhanced. This also applies to the following embodiments.

Figure 5 is a diagram showing how the ventilation parting member A is installed in the eaves (under water), and Figure 6 is a diagram in which the ventilation parting member A is installed in the eaves (above water). The ventilation parting member A is constructed by fitting the end of the shedding board 22 between the top board 2 and the intermediate board 3, and inserting the part below the intermediate board 3 between the shedding board 22 and the exterior wall material 25. It is attached to the end of the base plate 22 and fixed by nailing or the like. Then, an arabesque 27 is installed vertically so as to hide the back plate 1 of the ventilation parting member A. The gap between the bottom plate 4 and the outer wall material 25 is filled with a sealing material 28 and sealed. Moreover, a roofing material 23 is constructed on the roofing board 22.

FIG. 7 is a diagram showing how the ventilation parting member A is installed at the edge of the eaves, and the ventilation parting member A is attached to the end of the roofing board 22 in the same manner as shown in FIGS. Fix it by. Then, the space between the bottom plate 4 and the fascia 29 is sealed with a sealing material 28.

In the case of the construction methods shown in Figures 5 to 7, ventilation is provided between the attic and the outdoors, but in this case too, the ventilation parting member A acts in the same way as in the case of verges, Prevents water from entering indoors.

The present invention is as described above, and has a simple configuration and can be easily installed at the end of a roofing board, and is arranged so that the inward opening end face where the ventilation path of the ventilation member opens is separated from the slope of the draining material. Since a space is formed there, it has good ventilation, and rain and snow that may come in through the cut-up opening can be blown away by the vortex airflow generated in the space. This has the effect of preventing rain and snow from entering the indoor side through the ventilation member, and is installed by inserting the edge of the field board between the top board and the middle board. , it can improve the fire prevention performance of that part, and when used for ventilation in the attic, it has the effect of increasing the durability of the attic by promoting ventilation in the attic and drying the inside of the attic. Therefore, its industrial applicability is great.
