[0002]
[Prior art]
Conventionally, ventilation of a hut in a residential building has been performed from a ventilation hole or the like formed in the back of the eave or the wall of the shed, but there is a problem that hot air stops at the top of the building. In addition, when the roof structure is a dormitory, ventilation holes cannot be formed on the wall of the back of the hut.
[0003]
[Problems to be solved by the invention]
From October 1998, when the technical standards of the housing for which the JHF financing system was applied were revised to provide air intake holes on the back of the eaves and air exhaust holes, the ratio of the effective area of the air intake holes to the ceiling area is: It was established that it should be 1/900 or more, and the exhaust should be installed at the top of the back of the hut as much as possible, and the ratio of the effective area of the exhaust holes to the ceiling area should be 1/600 or more. The number of berths is increasing to keep costs down.
Therefore, there is a need for a ventilated roof structure that can cope with these laws and regulations and trends of the times, is inexpensive, has excellent workability, and conforms to the above technical standards.
In light of these circumstances, the present inventor has developed a roof tile that can be ventilated in the vicinity of the building (Japanese Patent Application No. 11-001678), but the effect is further increased by forming an air inlet at the eaves. This was developed for the purpose of providing an eaves ventilation structure and eaves ventilation member suitable for intake from the eaves.

[0023]
A spacer 10 is bonded to the back surface of the side wall 8 of the peripheral edge 7 with a space for fitting the eaves ceiling plate 14 between the receiving edge 9 and a top plate fitting portion 11 is formed. In the case where the spacers 10 have a short length of the ventilation material 2 and are connected to each other, the peripheral edge 7 alone is used to reinforce the strength when the strength is weak. Therefore, the spacer 10 can be omitted when the side wall 8 is thick. For this bonding method, any means such as an adhesive or a double-sided pressure-sensitive adhesive tape can be used.
[0024]
FIG. 2 is a perspective view showing a form in which the ventilation member 2 is provided with a windshield. In this embodiment, a horizontal and longitudinal cut 2A is formed at an arbitrary position at the height of the front and rear walls 3 and 4 of the ventilation material 2 until it reaches the center, and a windshield 12 is fitted in the cut 2A. Has been. That is, in places near the coast, strong winds may wind up in the winter, and there is a possibility that rain may enter the cabin 17 from the ventilation holes 6 of the ventilation material 2. If there is this windshield 12 ... The rainwater that is rolled up is also restricted from entering the cabin 17. In addition, invasion of pests can be prevented. A part of the windshield 12 can be replaced with an insect net, and an infinite number of small holes can be formed in the windshield 12 to serve as an insect net.
[0025]
FIG. 3 is a side view showing a second form of the peripheral edge 7. In this embodiment, a plurality of ribs 7 </ b> A are formed on the back surface of the side wall 8 to increase the strength of the side wall 8. Thereby, the spacer 10 in FIG. 1 can be omitted. Reference numeral 7 </ b> B in the figure denotes a positioning protrusion that is easily positioned by being caught on the upper surface of the ventilation material 2. In addition, between each said rib 7A and 7A, a foamed resin can be packed by integral molding by extrusion molding, and an intensity | strength can be raised.
[0026]
FIG. 4 is a side view of the eaves ventilation structure. Reference numeral 20 is a field edge (a thin material used for an attic, a vertical field edge), 14 is an eaves ceiling board, 15 is a nose cover board, 16 is a rafter, 17 is an eaves hut, and 18 is a nail. In the ventilation member 1, the back surface of the spacer 10 is applied to the front end surface of the field edge 13 located at the front portion of the field edge frame, and the nose cover plate 15 is applied to the front surface of the ventilation material 2 and fixed with nails 18 To do. In this case, a double-sided tape can be adhered to the back surface of the spacer 10 and adhered to the front surface of the field edge 20.
[0027]
The vertical edge 20 and the rear edge 19 are framed to form a field edge frame (see FIG. 5), but the edge of the edge not shown in FIG. 4 is nailed to the column 21 (see FIG. 5) as is well known. Fix it. The upper part of the nose cover plate 15 is fixed to the tip surface of the rafter 16 with a nail 18 as shown. Thereafter, the eaves ceiling plate 14 is fixed by fitting the front end of the eaves ceiling plate 14 to the top plate fitting portion 11 on the receiving plate 9.
[0028]
As a result, an eaves ventilation structure is formed. The eaves ventilation member can be arranged around the eaves if it is a dormitory. That is, the air that enters from below the ventilation holes 6 of the ventilation material 2 enters the back of the eave hut 17, passes through the rafters 16, reaches the back of the hut toward the ridge, and is exhausted from an exhaust port such as the top of the ridge. Thus, since air escapes from the eaves periphery to the building top, it is possible to provide a good ventilation effect.
[0029]
FIG. 5 is a side view showing a second form of the eaves ventilation structure. The same members as those in the above example are denoted by the same reference numerals and description thereof is omitted. In FIG. 5, reference numeral 19 denotes an edge of the back, 20 denotes a vertical edge (bridge), 21 denotes a pillar, 22 denotes an eaves girder, and 23 denotes a wall board. In this embodiment, as shown in the figure, the front surface of the eaves ventilation member 1 is fixed to the front surface of the back edge 19 and is ventilated from the front and rear eaves ventilation members 1, 1 to the eaves cabin back 17. . In this case, the front eaves ventilation member 1 can also be abolished.
[0030]
In the figure, the eaves ceiling board 14 is stretched horizontally, but the field frame can be fixed to the rafter 16 so that the rafter 16 is inclined. In that case, outside air that has entered through the ventilation holes 6 of the ventilation member 2 passes between the rafters 16 under the roof board (field board) and enters the back of the cabin inside the eaves girder 22 to promote ventilation.
[0031]
In addition, this invention is not limited to the said form example, A design change can be arbitrarily made | formed according to the objective. The ventilation hole 6 of the ventilation material 2 can be made to correspond to insect repellent by putting a thin cross partition in a square shape inside.
[0032]
【The invention's effect】
The present invention configured as described above has the following excellent effects.
[0033]
The eaves ventilation member can be disposed around the eaves of the eaves where the eaves ceiling plate is stretched, so that the eaves can be sufficiently sucked into the eaves.
[0034]
The eaves ventilation member can be nipped and pinched between the field edge and the nasal cover, so anyone can easily use it without having to use other materials or materials. There is an effect that it can be arranged.
[0035]
Since the eaves ventilation member can be fixed to the front of the back edge of the field frame, the eaves can be arranged near the wall when the eaves are narrow or the roof slope is low, and the length of the eaves is long. There is an effect that the time can be arranged back and forth.
[0036]

[0037]
The eaves ventilation member can be equipped with a windshield plate on the ventilation material, and has an effect of reliably preventing rainwater from entering the back of the hut even if rainwater is rolled up by strong winds.
[0038]
Since the eaves ventilation member can be formed by extrusion molding, there is an effect that the size, shape, etc. of the vent can be arbitrarily set.
[0039]
The eaves ventilation member can be supplied at a low cost, and the mounting effort is only nailing, so that the cost burden is light.
[0040]
The eaves ventilation structure has an eaves ventilation member fixed by nailing, so it can be constructed firmly, and since the eaves ventilation member is small, there is an inconspicuous effect from the outside.
[0041]
The eaves ventilation structure has the effect of preventing rainwater from entering because the ventilation material part is hidden behind the nose cover.
