Description

[Detailed description of the invention] [Technical field] This invention relates to an eaves structure for attic ventilation.

[Background technology]

Conventionally, in order to form ventilation holes for attic ventilation, the front protruding part of the crosspiece of the soffit panel was fixed to the underside of the nose cover.
Publication No. 72322).

However, if left as is, the front protruding part of the crosspiece will appear exposed on the underside of the nose comb, spoiling its appearance.
This method cannot be used unless the makeup nose comb is installed on the outside of the nose comb. Therefore, there is a problem that the structure is complicated and construction is time-consuming.

Furthermore, conventionally, there is a system in which columnar bodies are arranged intermittently and ventilation holes are formed between the members that sandwich these columnar bodies (Japanese Utility Model Publication No. 14132/1983).

However, since each columnar body is independent,
There is a problem in that a large number of columnar bodies must be individually attached to each other, and the number of on-site construction steps is large, making the construction time-consuming.

[Purpose of invention]

The purpose of this invention is to provide an eave structure that allows attic ventilation and is simple in construction and on-site construction.

[Disclosure of invention]

The eaves structure of this invention consists of a decorative eave board whose upper part is fixed to the eave part of the roof body, and a decorative eave board that is provided at the bottom of the back side of the decorative board and has notches intermittently along the longitudinal direction, and the area between the notches. A cross member is formed with a convex portion projecting to the back side of the eaves decorative board, and the end portion of the eaves side faces the tip of each convex portion, and is fixed to the convex portion using a fixing tool, and the space between each convex portion is fixed to the attic. The soffit base material is provided with a ventilation hole communicating with the soffit base material, and a soffit base material adhered to the entire lower surface of the soffit base material avoiding the ventilation hole.

According to the configuration of this invention, in order to form a ventilation hole, a crosspiece with a notch is provided on the back side of the eaves end decorative board, and the eaves ceiling base material is fixed to the convex part between the notches of the crosspiece with a fastener, so that ventilation in the attic is obtained and the following effects are obtained: Since the eaves ceiling base material is attached to the crosspiece on the back side of the eaves end decorative board, unlike the above-mentioned conventional example in which the eaves ceiling base material is provided on the underside of the nose cover, even if there is no two-part structure of the nose cover and the decorative nose cover, the eaves ceiling base material is not exposed and the structure is simplified.

In addition, since a single crosspiece with a plurality of protrusions formed by forming notches is used, unlike the second conventional example, in which multiple columnar bodies are each fixed independently, the crosspiece On-site construction for fixing is easy. Although it is necessary to process notches in the crosspiece, this process can be done in advance at a factory, etc., so it can be processed efficiently.

Embodiment An embodiment of this invention will be described with reference to FIGS. 1 to 3. In other words, this eave structure is the first
As shown in the figure and Fig. 2, attach the upper part to the mounting bracket 1.
The end of the eaves ceiling panel 5 is fixed to the lower part of the back side of the decorative eaves panel 3 which is fixed to the roof panel 2 via the crossbars 4, and the ventilation holes 6 provided in the crossbars 4 connect to the attic 7. It provides ventilation.

In detail, the eaves decorative panel 3 is a PVC extrusion molding.
It is made of GRC, wood, etc.
3 is attached to the bottom of the back surface of the plate. The plate 4 has notches 4a formed at intervals along the lengthwise direction. A protrusion 4 is formed between the notches 4a.
Let's call it b.

The soffit panel 5 is composed of a soffit base material 8 and a soffit base material 9, and is attached by attaching one end of the soffit base material 8 to the tip of the convex portion 4b of the crosspiece 4 using a fixing tool. It is fixed with nails 10, and the other end of the eaves soffit base material 8 is fixed to the shutter box 12 (previously attached to the upper part of the outer wall panel 13) via the mounting fitting 11. In this way, the notch 4a of the crosspiece 4 is surrounded by the soffit base material 8 of the crosspiece 4, thereby forming the ventilation hole 6. After installing the eave ceiling base material 8, the eave ceiling material 9 is pasted to the entire lower surface of the eave ceiling base material 8 so as not to block the ventilation holes 6. In this way, the outdoor area 14 and the attic space 7 are communicated through the ventilation hole 6. In addition, in FIG. 2, 3a is the drainage part of the eaves decorative board 3, and in FIG.
5 is an eaves gutter, and 16 is a roof tile.

As a result of this configuration, the air from outside 14 can be guided into the attic 7 through the ventilation hole 6, making it possible to ventilate the attic. Moreover, since the drainage part 3a of the eaves decorative board 3 covers the lower part of the ventilation hole 6, it is possible to prevent rainwater from entering into the attic 7 through the ventilation hole 6 due to upward wind.

The construction of the eave ceiling section involves fixing one end of the eave ceiling panel 5 to the eave decorative board 3 via the crosspiece 4, and
Since it is only necessary to fix the other end to the shutter box 12 via the mounting fitting 11, construction is extremely easy.

In particular, since one crosspiece 4 having a plurality of protrusions 4b formed by forming notches 4a is used, unlike the conventional example in which a large number of columnar bodies are each fixed independently, the crosspiece 4 On-site construction for fixing is easy. Although it is necessary to process the notches 4a in the crosspiece 4, this process can be performed in advance at a factory or the like, so that the notches 4a can be formed efficiently.

In addition, since the eave ceiling base material 8 is attached to the crosspiece 4 on the back side of the eaves decorative board 3, unlike the second conventional example in which the eave ceiling base material is provided on the underside of the nose cover, the nose cover and the decorative nose Even if it does not have a double structure with a cover, the eave ceiling base material 8 is not exposed and visible, and the structure is simple.

[Effect of idea]

In the eaves structure of this invention, in order to form ventilation holes, a crosspiece with a notch is provided on the back side of the decorative eaves board, and the eaves base material is fixed with a fixing device against the convex part between the notches of the crosspiece. Therefore, attic ventilation can be achieved and the following effects can be obtained. In other words, since the soffit base material is attached to the crossbars on the back side of the decorative eaves board, unlike the conventional example where the soffit base piece is provided on the underside of the nose cover, a double structure of the nose cover and the decorative nose cover is used. Even if it is not used, the structure is simple because the eaves base material will not be exposed and visible.

Also, by forming notches, a plurality of convex portions are formed.
Because it uses real crossbars, unlike the second conventional example in which multiple columnar bodies are each fixed independently, the advantage is that on-site construction for fixing the crossbars is simple. There is.
