Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves ceiling ventilation rim used for an eaves ceiling of a building, and more particularly to an eaves ceiling ventilation rim used for an eaves ceiling of a wooden building such as a wooden house.

The attic of buildings such as wooden houses is easy to maintain high humidity and temperature. When high humidity and temperature are maintained for a long period of time, insects such as termites and rot fungi may propagate and the wood may be eaten and damaged. Therefore, conventionally, an eaves ceiling ventilation edge member having ventilation holes is attached to the eaves ceiling of a building such as a wooden house in order to ventilate the attic. Usually, the eaves ceiling ventilation frame has ventilation holes formed at appropriate positions, and is attached to the eaves end side or the wall side edge of the ceiling board.

Also, the eaves of the building are susceptible to the spread of fire from the neighboring house, and when an eaves ceiling ventilation rim is attached to the ceiling board, flames and sparks are transmitted through the ventilation holes formed in the eaves ceiling ventilation rim. The number of ventilation holes that can be formed in the eaves ceiling ventilation edge, the total area, the shape, etc. are regulated by laws and regulations, etc. It is formed so as to conform to such laws and regulations.

However, if an eaves ceiling ventilation rim material with ventilation holes is attached to the ceiling board, when wind and rain are strong, the crosswinds are rolled up against the outer wall of the building, causing rainwater and splashes to pass through the ventilation holes. There is a risk that the inside of the attic will be wetted and the wood in the attic will be corroded. In order to solve such a problem, as a conventional eaves ceiling ventilation rim material, for example, an eaves ceiling ventilation rim material in which a shielding plate for returning water is attached to the rear position of a metal plate in which ventilation holes are formed.

Utility Model Registration No. 3077483

However, according to the eaves ceiling ventilation edge member 110 shown in FIG. 7, the shielding plate 112 prevents rainwater and splashes (hereinafter also referred to as rainwater) that have passed through the ventilation hole 111 from blowing into the attic to some extent. However, since there is a ventilation gap 113, there is a possibility that a part of rainwater or the like may be blown into the attic, and the intrusion of rainwater or the like cannot be sufficiently prevented.

Further, according to the eaves ceiling ventilation edge member 130 shown in FIG. 8, the ventilation holes 131 and the ventilation holes 136 formed by punching work in the direction in which rainwater or the like is blown respectively (from the outside of the ceiling board 101 to the inside of the attic. The rainwater etc. are easy to blow in, and even if the shielding board 132 exists, some rainwater etc. may blow up to the attic, rainwater etc. There was a problem that it was not possible to sufficiently prevent the intrusion.

In addition, according to the eaves ceiling ventilation edge member 140 shown in FIG. 9, the shapes of the substrate 145 and the shielding plate 142 are complicated, for example, between the first shielding portion 142a and the second shielding portion 142b, or between the gaps. Since there are places where rainwater or the like tends to accumulate, such as the lower part of 148, rainwater or the like that has once passed through the ventilation hole 141 and blown into the eaves ceiling ventilation rim 140 is difficult to be discharged. There was a risk of accumulating inside. If rainwater or the like accumulates in the eaves ceiling ventilation rim 140, the eaves ceiling ventilation rim 140 may be corroded, or the rainwater may evaporate and enter the attic. Further, most of the ventilation path (see arrow E) is perpendicular to the direction from the outside of the ceiling board 101 to the inside of the attic, and a large detour path is ensured for a long time. However, it was difficult to provide a sufficient ventilation function. Further, since the shapes of the substrate 145 and the shielding plate 142 are complicated, there is a problem that the labor for manufacturing is complicated and the manufacturing cost increases.

The present invention has been made in view of the above-described points, and an object thereof is to provide an eaves ceiling ventilation rim that can exhibit an excellent ventilation function and can sufficiently prevent the intrusion of rainwater and the like. There is to do.

In order to solve the above-described problems, the present invention provides the following.
(1) having two rectangular plate-like parts arranged so as to face each other with a predetermined interval in the vertical direction;
Each rectangular plate-shaped portion has a plurality of recesses, and ventilation holes are formed on the side surfaces of the recesses.

Here, the structure of the edge material for eaves ceiling ventilation of said (1) is demonstrated using FIG.
FIG. 1 is an enlarged perspective view schematically showing a part of an edge material for eaves ceiling ventilation according to the present invention. In the figure, the state where the edge material for eaves ceiling ventilation is broken is shown.
FIG. 1 is a drawing used for easy understanding of the present invention. Of course, the present invention is not limited to FIG.

The eaves ceiling ventilation rim 1 has two rectangular plate-like parts 2 and 3 arranged so as to face each other with a predetermined interval in the vertical direction. The rectangular plate-like portion 2 has a recess 4, and a ventilation hole 5 is formed on the side surface of the recess 4. In addition, the rectangular plate-shaped portion 3 has a recess 6, and a ventilation hole 7 is formed on a side surface of the recess 6. In the figure, S indicates the flow of ventilation, 4a indicates the bottom surface of the recess 4, 6a indicates the bottom surface of the recess 6, 8 indicates the exterior of the building, and 9 indicates the interior of the attic.

According to the invention of the above (1), a total of four members of the rectangular plate-like portions 2 and 3, the bottom surface 4 a of the recess 4 and the bottom surface 6 a of the recess 6 are in the direction in which rainwater or the like blows (from the outside 8 of the building to the attic It is perpendicular to the direction toward the interior 9). Accordingly, rainwater or the like from the outside 8 of the building to the inside of the eaves ceiling ventilation rim 1 avoids the rectangular plate portion 2 and the bottom surface 4a of the recess 4 and passes through the ventilation holes 5 formed in the side surface of the recess 4. As long as it is not blown in an oblique direction, it does not penetrate into the eaves ceiling ventilation edge 1. Furthermore, rainwater or the like that reaches the interior of the eaves ceiling ventilation rim 1 changes the traveling direction so as to avoid the bottom surface 6a of the recess 6 and the rectangular plate-shaped portion 3, and the ventilation hole 7 formed on the side surface of the recess 6 is provided. As long as it is not blown in an oblique direction, it does not enter the interior 9 of the attic.
Thus, according to the invention of the above (1), the intrusion direction of rainwater or the like is made by elevating the ceiling of the eaves by the total of four members including the rectangular plate-like portions 2 and 3, the bottom surface 4 a of the recess 4 and the bottom surface 6 a of the recess 6. An air passage that does not allow rainwater or the like to enter the interior 9 of the attic is formed unless it is changed a plurality of times in the edge material 1, so that rainwater and the like can be sufficiently prevented from entering.

Further, compared with the eaves ceiling ventilation edge member 140 and the like shown in FIG. 9, air is less likely to stay in the eaves ceiling ventilation edge member 1 because the ventilation path formed in the eaves ceiling ventilation edge member 1 is short. Can demonstrate excellent ventilation function. On the other hand, there is no place where rainwater or the like tends to accumulate, and rainwater that has once entered the eaves ceiling ventilation rim 1 is easily discharged downward. The eaves ceiling ventilation rim 1 is not corroded, and the rainwater or the like does not evaporate and enter the interior 9 of the attic.

Furthermore, the present invention provides the following.

The ventilation hole is formed by making a plurality of cuts in a rectangular plate-like portion and performing a pressing process.

According to the invention of (2), it is possible to form the concave portion and the ventilation hole at the same time as compared with the case where the concave portion is once formed in the rectangular plate-shaped portion and the ventilation hole is generated on the side surface of the concave portion. Yes, it is possible to reduce the labor of manufacturing eaves ceiling ventilation rims. As a result, the manufacturing cost can be reduced.

Furthermore, the present invention provides the following.
(3) The edge material for eaves ceiling ventilation according to (1) or (2) above,
Consisting of at least two metal plates,
Part of the two metal plates constitutes a rectangular plate portion, respectively.

According to the invention of (3), it is possible to easily perform processing and molding, compared with the case of forming a single metal plate to form two rectangular plate-like portions, and the eaves ceiling ventilation edge material The labor of manufacturing can be reduced. As a result, the manufacturing cost can be reduced.

Furthermore, the present invention provides the following.
(4) The eaves ceiling ventilation edge material according to any one of (1) to (3) above,
The ventilation holes have an elongated shape extending in the short side direction of the rectangular plate-shaped portion, and are arranged at predetermined intervals in the long side direction of the rectangular plate-shaped portion.

They are arranged at a predetermined interval. Specifically, each set is arranged in a rectangular plate-like portion 15a with a gap of 30.8 mm, and the recesses 15b included in each set are arranged with a gap of 2.8 mm. The area (ventilation opening area) of the ventilation hole 11 per 1 m in the long side direction length of the lower plate 15 is 150.5 cm ² / m.
A sheet-like fire-resistant thermal expansion member 17 is provided on the back side of the rectangular plate-like portion 15a along the long side direction of the rectangular plate-like portion 15a.

4A is a plan view schematically showing an upper plate of the eaves ceiling ventilation edge member shown in FIG. 1, and FIG. 4B is a cross-sectional view taken along the line BB in FIG.
The upper plate 12 has a rectangular plate-like portion 12a having a long side direction length of 3030 mm and a short side direction length of 42.5 mm.

[Second Embodiment]
Next, as a second embodiment of the present invention, a case where the present invention is applied to an eaves ceiling ventilation edge member used on the eaves ceiling wall side will be described.
FIG. 5 is a cross-sectional view schematically showing an eaves ceiling ventilation rim material according to the second embodiment. Fig.6 (a) is a top view which shows typically the lower board of the edge material for eaves ceiling ventilation shown in FIG. 5, (b) is the CC sectional view taken on the line.

The eaves ceiling ventilation rim 20 includes the same lower plate 15, upper plate 12, and thermal expansion member 17 as the eaves ceiling ventilation rim 10 according to the first embodiment. An extension plate 23 made of a galtite steel plate is attached to an edge portion 15 c formed on the lower plate 15 of the eaves ceiling ventilation edge member 20 by an adhesive seal 22. The lower plate 15 and the extending plate 23 form a groove 21 for attaching the eaves ceiling ventilation edge member 20 to the exterior plate 97.

Since the extended plate 23 is attached to the edge 15c of the lower plate 15 by the adhesive seal 22, it is possible to change the angle of the extended plate 23 with respect to the edge 15c. In contrast, it is possible to attach the edge member 20 for eaves ceiling ventilation.

As described above, according to the eaves ceiling ventilation rims 10 and 20, the intrusion direction of rainwater or the like is changed to the eaves ceiling ventilation rim by the total of the four members of the rectangular plate portions 12a and 15a, the bottom surface of the recess 12b, and the recess 12b. Since a ventilation path that does not allow rainwater or the like to enter the inside of the attic is formed unless it is changed a plurality of times within 1, the entry of rainwater and the like can be sufficiently prevented. Further, since the ventilation path formed in the eaves ceiling ventilation edges 10 and 20 is shorter than the eaves ceiling ventilation edges 140 and the like shown in FIG. It is hard to stay and can exhibit an excellent ventilation function. Further, the eaves ceiling ventilation edges 10 and 20 are configured such that there is no portion where rainwater or the like easily collects, and rainwater or the like once entering the eaves ceiling ventilation edges 10 and 20 is easily discharged. Therefore, rainwater or the like does not accumulate and the eaves ceiling ventilation edges 10 and 20 are not corroded, and the rainwater or the like does not evaporate and enter the inside of the attic.

Further, since the ventilation holes 11 and 16 are formed by making a plurality of cuts in the rectangular plate-like parts 15a and 12a and performing a pressing process, the recesses 15b and 12b and the ventilation holes 11 and 16 are formed at the same time. It is possible to reduce the labor of manufacturing the eaves ceiling ventilation rims 10 and 20. As a result, the manufacturing cost can be reduced.
In the present invention, the method of forming the ventilation hole is not limited to the above-described example. For example, a metal plate in which a plurality of through holes are formed in a metal plate or the like by punching and the through holes are formed. For example, the ventilation hole may be formed by performing a pressing process.

Further, the eaves ceiling ventilation edges 10 and 20 are composed of at least an upper plate 12 and a lower plate 15 made of a galtite steel plate, and a part of the upper plate 12 and the lower plate 15 constitute rectangular plate-like portions 12a and 15a, respectively. Therefore, as compared with the case where one metal plate is formed to form two rectangular plate-like portions, the processing and molding can be performed easily, and the eaves ceiling ventilation edges 10 and 20 can be manufactured. Time and effort can be reduced. As a result, the manufacturing cost can be reduced.
In the present invention, the rectangular plate portions 12a and 15a are preferably metal plates. This is because it has excellent heat resistance and mechanical strength. Such a metal plate is not particularly limited, and may include, for example, a stainless steel plate, an aluminum steel plate, a paint-melted 55% aluminum-zinc alloy-plated steel plate, and the like in addition to the above-described galtite steel plate. Further, in the above-described embodiment, the case where the rectangular plate-like portions 12a and 15a are configured by parts of different metal plates (upper plate 12 and lower plate 15) has been described, but the present invention is limited to this example. For example, it is good also as manufacturing the edge material for eaves ceiling ventilation which has two rectangular plate-shaped parts by shape | molding one metal plate.

Further, according to the eaves ceiling ventilation edges 10 and 20, the ventilation holes 11 and 16 have an elongated shape extending in the short side direction of the rectangular plate-like portions 15a and 12a, and the rectangular plate-like portions 15a and 12a Since they are arranged at predetermined intervals in the long side direction (FIGS. 3 and 4), the rectangular plate-like portions 15a and 12a between the recesses 15b and 12b, the bottom surfaces of the recesses 15b and 12b, and the like are It functions as a reinforcing material for stabilizing the shape of the ventilation edge members 10 and 20. Therefore, it is possible to form a large number of large ventilation holes 11 and 16 while ensuring the mechanical strength of the eaves ceiling ventilation rims 10 and 20, and the ventilation opening area can be increased. In the present invention, the number and shape of the ventilation holes formed in the rectangular plate-shaped portion are not particularly limited, and can be appropriately changed within the limits of laws and regulations.

Moreover, according to the eaves ceiling ventilation rims 10 and 20, since the thermal expansion member 17 is provided between the rectangular plate-like portions 15a and 12a, the thermal expansion member 17 is heated by a fire in a neighboring house or the like. Then, since the thermal expansion member 17 expands and the ventilation holes 11 and 16 are shielded, it is possible to surely prevent the entry of flames or sparks into the interior of the attic.

Further, according to the eaves ceiling ventilation edges 10 and 20, the upper plate 12 having the same shape is used. Therefore, by replacing the lower plate 15, the eaves ceiling ventilation edge 10 for eaves can be obtained. It can be used as the eaves ceiling ventilation edge material 20 for. Further, by attaching the extension plate 23 to the edge portion 15 c of the lower plate 15 of the eaves ceiling ventilation edge member 10 with the adhesive seal 22, the lower plate 15 of the eaves ceiling ventilation edge member 20 can be obtained. Therefore, it is easy to adjust the number of stocks, and the manufacturing cost can be reduced.
