Description

The present invention relates to an eaves ventilation material, and more specifically, to an eaves ventilation material having excellent fire resistance and ventilation performance, which is installed on the back of an eave, for example.

In recent years, the importance of ventilation behind the cabin has been increasing with the demand for improving the durability of the house and the indoor thermal environment. It is conceivable to provide a ventilation port at the eaves for ventilation in the back of the cabin, but providing a ventilation port at the eaves, that is, an opening is subject to fire protection regulations, so unless it passes the fire protection test, it will be carried out. (There are no restrictions on the case of installing ventilation openings in the building).

From this point of view, the applicant of the present application can first perform the work on the actual site without using any special technology or material as much as possible, and can pass the fire protection test. (Patent Document 1: Japanese Patent Application Laid-Open No. 2013-44129). The eaves back structure according to the proposal is to place an eaves ventilation material made by bending a sheet metal and incorporating a thermal expansion material and a resin ventilation material in the gap between the outer wall material and the fascia base material. Is.

However, in the case of this eaves back structure, the eaves ventilation material is installed in the gap between the outer wall material and the fascia base material, and the gap becomes an air inflow space, so that sufficient air inflow occurs. There is a problem that it is difficult to secure space.

As shown in FIGS. 1 to 4, the eaves ventilation material A according to the present invention has a top plate 1 having a ventilation portion 2 extending in the length direction in the middle, and ventilation connected to the lower side of the ventilation portion 2. A space is provided between the material storage unit 3 and the ventilation material 5 having a quadrangular side surface, which is housed in the ventilation material storage unit 3 together with the thermal expansion material 4, and the inner side surface 6 of the ventilation material storage unit 3. It is composed of facing plates 7 that are opposed to each other. The top plate 1, the ventilation material storage portion 3, and the facing plate 7 are all made of a steel plate or an equivalent material.

The bottom surface 9 of the ventilation material storage portion 3 is made sloped by making the inner side surface 6 vertically longer than the outer side surface 8. Thus, an air inflow space 10 is created under the thermal expansion material 4 and the ventilation material 5. A portion extending from the lower part of the inner side surface 6 to the bottom surface 9 is opened in an elongated shape to serve as an air inflow port 11. A large number of air inlets 11 are arranged side by side in the length direction (see FIG. 2). In this case, the air entering from the air inflow port 11 escapes from the lower surface to the upper surface of the ventilation material 5 through the air inflow space 10. As described above, the air inflow port 11 is separated from the lower surface of the ventilation material 5 to secure the air inflow space 10, so that the element that blocks the lower surface of the ventilation material 5 disappears and the entire surface is opened, which is good. It becomes a ventilation state.

The bottom surface 9 of the ventilation material storage portion 3 is extended beyond the outer side surface 8, and the eaves ceiling material charging portion 12 is formed between the extension portion 9a and the upper surface plate 1. Further, the lower end of the facing plate 7 is extended diagonally upward, and the eaves ceiling material charging portion 13 is formed between the extension portion 7a and the upper surface plate 1.

For example, the top plate 1 and the ventilation material storage portion 3 can be formed by bending one metal plate (particularly, see FIG. 3). That is, first, the upper surface plate 1 is bent at a right angle to form a half portion 1a and the inner side surface 6, and the lower end of the inner side surface 6 is bent diagonally upward to form the bottom surface 9. .. Next, the bottom surface 9 is extended and folded back, and the end portion thereof is bent in the vertical direction to form the bottom surface extension portion 9a and the outer side surface 8, whereby the inner side surface 6, the bottom surface 9 and the outer side surface 8 are formed. A ventilation material storage portion 3 surrounded by the side surface 8 is formed. Then, the upper end of the outer side surface 8 is horizontally bent to form the other half portion 1b of the upper surface plate 1. An opening for forming the air inlet 11 is provided in advance. Further, since the eaves ventilation material A is installed by fastening the upper surface plate 1 to the field edge 20, a large number of screw holes 15 are formed at both end edges in the width direction of the upper surface plate 1. To.

Further, the upper end of the facing plate 7 is horizontally bent and extended, the extension portion thereof is brought into contact with the back surface of the half portion 1a of the upper surface plate 1, and the end portion thereof is at the end portion of the half portion 1a of the upper surface plate 1. By wrapping it, it can be fixed to the half portion 1a of the top plate 1.

The ventilation material 5 has a large number of ventilation passages 5a for ventilating in the short width direction (vertical direction in FIGS. 1 to 3), and is usually made by stacking a large number of plastic plates in which ventilation passages exiting in the width direction are arranged side by side. , Can be manufactured by a known method of fusing with heat rays to form a predetermined width and integrating them (see Patent No. 2610342, etc.). Further, the thermal expansion material 4 has a long plate shape, and is sandwiched between the inner side surface 6 of the ventilation material storage portion 3 and the ventilation material 5 on the upper side of the air inlet 11. The thermal expansion material 4 does not necessarily have to be a series, but may be a discontinuous one in which long ones are juxtaposed. Normally, the thermal expansion material 4 is separated from the ventilation material 5, but it may be inserted in the intermediate portion thereof at the time of manufacturing the ventilation material 5 and integrated with the ventilation material 5 (see FIG. 4). ..

As will be described later, the eaves ventilation material A having the above configuration can be installed at various locations in the eaves, but in any case, air is opened from the lower part of the inner side surface 6 to the bottom surface 9. It enters the air inflow space 10 from a large number of air inlets 11 and then enters into the innumerable ventilation passages opened on the lower surface of the ventilation material 5, rises, and is discharged from the upper surface opening.

Then, in the event of a fire or the like, the thermal expansion material 4 expands and completely blocks the air inflow space 10 and the air inlet 11, so that the flame may enter the eaves through the eaves ventilation material A. Be blocked. In addition, rain and snow that may enter from the air inlet 11 cannot rise up and pass through the narrow and long ventilation path, so that rain and snow are prevented from entering.
