DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a short eave eave ventilation structure.

[0002]

2. Description of the Related Art FIG. 7 shows a conventional short eave eave ventilation structure 100 (corresponding to a sectional view taken along line AA in FIG. 6).
Here, the short eaves means a roof eave part which does not have a width (projection amount) sufficient to be generally called an eave ceiling. For reference, the L dimension in FIG.
0 mm. The eaves ventilation structure 100 will be briefly described according to the construction procedure. An eaves ceiling material 103 is provided in a depth space between a fascia base 101 and a building outer wall 102, and a slit-shaped ventilation is provided for the eaves ceiling material 103. A transition plate 105 having a hole (not shown) is attached. Then, the decorative material 106 is attached so as to cover the front of the nose cover 101.

[0003] As an example of providing such a short eaves portion with a ventilation structure, Japanese Patent No. 3076544 is known. On the other hand, separately from the construction structure / procedure described above, a receiving member (not shown) for the connecting plate 105 is previously attached to the concealed base 101, and the connecting plate 1 is connected via the receiving member.
05, and then the eaves ceiling material 1
In some cases, a decorative material 106 is attached to the nose cover 101 while hiding the tip of the eave ceiling material 103.

FIG. 8 shows a conventional eave ventilation structure 100 for a building of a type called an alcove (a part of a building outer wall 102 is retracted to form a space below the building). It is an example. In this case, the building outer wall 102 vertically hanging down following the eaves ceiling material 103 and the transition board 105 is particularly called a “hanging wall”, and a lower end of the hanging wall is formed with a second eave ceiling material 107. It has been said that it is necessary to provide a hanging wall parting line 108 to make up the connection.

[0005]

A conventional eave ventilation structure 10
0 (see FIG. 7 and FIG. 8), the nose cover 101, the eaves ceiling material 103, the transition board 105, the decorative material 106, etc. are separately provided, and the eaves ceiling material 103 is particularly indispensable for the attachment of the transition board 105. In some cases, this was not possible. For this reason, the number of parts is increased as a whole, and the construction may be troublesome and costly.

[0006] Further, it is necessary to finish the building outer wall 102 as an "outer wall" up to the height immediately adjacent to the eave ceiling material 103, and the building outer wall 102 of an alcove type building is required.
In the case of (hanging wall) etc., the burden on the construction will increase even in this regard. In terms of external appearance, the structure in which the building outer wall 102 is exposed immediately below the decorative material 106 may be perceived by some viewers as having a thin low-grade feeling as a whole of the eaves ventilation structure 100. In particular, in an alcove-type building, since the hanging wall partition 108 is required, each part is present in the form of being separated from each other with the building outer wall 102 (hanging wall) interposed therebetween. In some cases, it was difficult to obtain a sense of unity in sex.

On the other hand, since the eave ventilation structure 100 is mainly used for short eaves, the area from the ventilation hole (not shown) of the crossing plate 105 to the back of the cabin is extremely close. There was a possibility that rainwater might enter the back of the hut through the ventilation holes. The present invention has been made in view of the above circumstances, and aims at facilitating workability and reducing the cost by reducing the number of parts, and assuming that a sense of unity in appearance is obtained. The purpose of the present invention is to provide an eaves ventilation structure of a short eave that can be obtained.

Another object of the present invention is to provide a short eave eave ventilation structure capable of preventing rainwater from entering the back of a shed.

[0009]

In order to achieve the above object, the present invention takes the following measures. That is, the eaves ventilation structure of the short eaves according to the present invention, an upper decorative material covering the nose cover under the roof eaves formed with the short eaves, and a lower decorative material covering the outer building wall on the lower side of the upper decorative material. A crossover portion provided with a ventilation hole extending in the vertical direction by being inserted into a depth space between the lower end portion of the upper decorative material and the upper end portion of the lower decorative material. At least one and the crossover plate are integrally connected.

As described above, according to the present invention, the upper decorative material and the lower decorative material can be substantially attached to the blindfold base (the crossover portion is integrated with the upper decorative material or the lower decorative material). Has been converted). Therefore, ease of construction and cost reduction can be achieved. In addition, since a sense of unity is obtained from the upper decorative material to the lower decorative material, a solid feeling is obtained. In addition, it is preferable to provide an eaves ceiling engaging portion at the lower end of the lower decorative material, which can be connected to the eaves ceiling material.

In this way, in an alcove-type building, it is possible to completely cover the outer wall (that is, the hanging wall) of the building up to the second eave ceiling material with the lower decorative material. Therefore, the appearance is further improved, and the outer wall (hanging wall) of the building can be formed of the base material. In other words, since it is not necessary to construct the building outer wall (hanging wall) as a so-called “outer wall”, the building outer wall (hanging wall) can be made unnecessary.

A water return material can be provided on the crossover plate so as to cover the upper side of the opening of the ventilation hole. By doing so, it is possible to prevent rainwater from entering the back of the hut.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 4 show an embodiment of a short eave eave ventilation structure 1 (corresponding to a sectional view taken along line AA in FIG. 6) according to the present invention. As is clear from FIG. 1, in the eave ventilation structure 1 of the present embodiment, an upper decorative material 3 provided so as to cover a nose cover 2 provided on a roof eave, and an upper decorative material 3 A lower decorative material 5 provided so as to cover a building outer wall 4 on the lower side of the
