Description

本発明は、鼻隠しや破風を始めとする化粧板の機能、及び屋根裏に換気構造を形成する換気材の機能を有する換気化粧部材、並びにその施工方法に関する。   The present invention relates to a ventilation decorative member having a function of a decorative board such as a nasal concealment and a windbreak, and a function of a ventilation material for forming a ventilation structure in an attic, and a method for constructing the ventilation decorative member.

住宅の屋根裏の劣化等を防止するため、従来から、軒天井裏や天井裏に換気構造が設けられている。このような換気構造としては、例えば、図８に示すように、軒天井部２０と壁部３０との間に軒元換気材６０を取り付ける構造や、軒天井部２０と、鼻隠し４０が取り付けられる下地材５０との間に、軒先換気材７０を取り付ける構造等が広く用いられている。   In order to prevent the deterioration of the attic of a house, conventionally, ventilation structures are provided on the eaves ceiling and the ceiling. As such a ventilation structure, for example, as shown in FIG. 8, a structure in which the eaves ventilation part 60 is attached between the eaves ceiling part 20 and the wall part 30, or the eaves ceiling part 20 and the nose cover 40 are attached. The structure etc. which attach the eaves ventilation material 70 between the base materials 50 to be used are used widely.

しかし、これらの換気材を屋根裏に取り付けるためには、換気材を固定する換気材用の下地材を予め取り付ける必要があり、更に、換気材を下側からこの下地材に取り付ける必要がある。この換気材の取り付け作業は、鼻隠し等の化粧部材の取り付け作業とは別途に行なう必要があり、また、下側からの作業となるので、多くの作業工数を要する。   However, in order to attach these ventilation materials to the attic, it is necessary to attach a base material for the ventilation material for fixing the ventilation material in advance, and it is necessary to attach the ventilation material to the base material from the lower side. This ventilation material attaching work needs to be performed separately from the attaching work of the decorative member such as a nose cover, and since it is work from the lower side, it requires a lot of work steps.

そこで、このような換気材の取り付け作業の工数を削減するため、鼻隠しや破風のような化粧板と、換気材とを一体成形した部材を用いて、化粧板の取り付けと換気材の取り付けを、１つの作業で行なうことが提案されている。例えば、特許文献１には、金属からなる鼻隠しと換気材の一体成形部材が提案され、特許文献２には、窯業系材料等からなる鼻隠し又は破風と換気材の一体成形部材が提案されている。   Therefore, in order to reduce the number of man-hours for attaching such a ventilation material, the decorative plate is attached and the ventilation material is attached by using a member in which a decorative plate such as a nasal cover or a gust of wind and a ventilation material are integrally formed. It has been proposed to do it in one operation. For example, Patent Document 1 proposes an integrally molded member of a nasal concealment and a ventilation material made of metal, and Patent Document 2 proposes an integral molding member of a nasal concealment or a blast and ventilation material made of a ceramic material or the like. ing.

実開平５−３８１４２号Japanese Utility Model Publication No. 5-38142 特開平７−２２９２５６号JP-A-7-229256

ここで、鼻隠しや破風といった化粧板は、装飾的な多様性が求められ、色、模様、形状等において、多くのバリエーションを有することが望まれる。従って、例えば、一体成形部材の材料として金属材料を用いる場合には、装飾的な多様性の要望を満たすことは困難となる。また、換気材は、破損等が生じにくく、換気口の詰まりが生じたときのメンテナンスが容易であるといった、耐久性、メンテナンス性に優れた性能が要求される。従って、例えば、一体成形部材の材料として窯業系材料を用いる場合には、耐久性、メンテナンス性の要求を満たすことは困難となる。
つまり、特許文献１、２に記載された一体成形部材では、全て同一の材料から構成されるので、化粧板と換気材の両方の機能において、最適な材料を適用することはできない。 Here, a decorative board such as a nasal cover or a gust of wind is required to have a variety of decorations, and it is desired to have many variations in colors, patterns, shapes, and the like. Therefore, for example, when a metal material is used as the material of the integrally molded member, it is difficult to satisfy the demand for decorative diversity. Further, the ventilation material is required to have excellent durability and maintainability such that damage or the like hardly occurs and maintenance is easy when the ventilation port is clogged. Therefore, for example, when a ceramic material is used as the material of the integrally molded member, it is difficult to satisfy the requirements for durability and maintainability.
In other words, since the integrally molded members described in Patent Documents 1 and 2 are all made of the same material, it is not possible to apply an optimum material in the functions of both the decorative board and the ventilation material.

また、施工後ある期間が経過すると、破損や換気口の詰まり等によって、特に、換気材の部分を交換しなければならない事態が生じる場合が多い。この場合、特許文献１、２に記載された一体成形部材では、換気材の部分を交換するためには、まだ使用可能な化粧板の部分を含めて全体を交換する必要があり、交換費用が多くかかる問題が生じる。   In addition, when a certain period of time elapses after construction, there are many cases in which a part of the ventilation material has to be replaced particularly due to breakage or clogging of the ventilation opening. In this case, in the integrally molded member described in Patent Documents 1 and 2, in order to replace the ventilation material part, it is necessary to replace the entire part including the part of the decorative plate that can still be used. Many such problems arise.

従って、本発明の目的は上述の問題を解決して、化粧板としても換気材としても最適な材料を用いることができ、破損等による交換に際しても交換費用も低減できる換気化粧部材、及びその施工方法を提供することにある。   Accordingly, the object of the present invention is to solve the above-mentioned problems, and to use a ventilation decorative member that can use an optimum material as a decorative board and a ventilation material, and can reduce the replacement cost even when it is replaced due to breakage, etc., and its construction It is to provide a method.

化粧板部分２の取付面の下部には、換気材部分４と接続するための凸部６ａが設けられ、この凸部６ａの断面形状は略矩形である。なお、化粧板部分２の取付面において、凸部２ａの上側に設けられた凹部は、化粧板部分２を軽量化するための肉抜きである。また、化粧板部分２の外面に設けられた段差は、主に装飾を目的にしたものである。   A convex portion 6a for connecting to the ventilation material portion 4 is provided at the lower part of the mounting surface of the decorative plate portion 2, and the sectional shape of the convex portion 6a is substantially rectangular. In addition, in the attachment surface of the decorative board part 2, the recessed part provided above the convex part 2a is the lightening for reducing the decorative board part 2 in weight. Further, the step provided on the outer surface of the decorative plate portion 2 is mainly for decoration purposes.

＜換気材部分の説明＞
次に、換気材部分４について更に詳細な説明を行なうと、紙面左端に、略コの字型の凹部６ｂが設けられ、紙面中央の中央面部４ｃに換気口４ａが設けられ、紙面右端に、上辺が下辺より長い略コの字型の軒天係合用凹部４ｂが設けられている。換気材部分４の長手方向の長さは、化粧板部分２と同じ長さＬとなる。 <Explanation of ventilation material part>
Next, the ventilation material portion 4 will be described in more detail. A substantially U-shaped concave portion 6b is provided at the left end of the paper, a ventilation port 4a is provided at the central surface portion 4c at the center of the paper, and at the right end of the paper. An approximately U-shaped eaves-top engaging recess 4b whose upper side is longer than the lower side is provided. The length of the ventilation material portion 4 in the longitudinal direction is the same length L as that of the decorative plate portion 2.

ここで、左端の凹部６ｂは、凸部６ａの略矩形の断面形状に対応するように成形されているが、コの字型の開口部の先端がやや狭まるようになっている。従って、凸部６ａと嵌合するときに、凹部６ｂの先端部が開かれる状態になるので、金属材料の弾性によるバネ力が生じ、このバネ力により凸部６ａと凹部６ｂの嵌合を強化することができる。
なお、凸部６ａと凹部６ｂの嵌合を更に強固にするため、ネジ等の固定部品や接着剤を用いることもできる。 Here, the recess 6b at the left end is formed so as to correspond to the substantially rectangular cross-sectional shape of the protrusion 6a, but the tip of the U-shaped opening is slightly narrowed. Accordingly, when the convex portion 6a is fitted, the tip of the concave portion 6b is opened, so that a spring force is generated by the elasticity of the metal material, and this spring force strengthens the fitting between the convex portion 6a and the concave portion 6b. can do.
In addition, in order to further strengthen the fitting between the convex portion 6a and the concave portion 6b, a fixing component such as a screw or an adhesive can be used.

次に、中央面部４ｃに設けられた換気口４ａについて説明すると、換気口４ａの大きさ、形状、設置間隔は、従来の軒先換気材に設けられる換気口と同様に設定することができる。また、中央面部４ｃには、換気のための空気の流れをガイドするガイド板４ｄも設けられている。   Next, the ventilation port 4a provided in the central surface portion 4c will be described. The size, shape, and installation interval of the ventilation port 4a can be set in the same manner as the ventilation port provided in the conventional eaves ventilator. In addition, a guide plate 4d that guides the flow of air for ventilation is also provided on the central surface portion 4c.

また、右端の軒天係合用凹部４ｂは、化粧板部分２と下地材５０が当接したときに、軒天井材２０と嵌合する位置に設けられている。この軒天係合用凹部４ｂの開口部は、軒天井材２０の厚みに対応する寸法に成形されているが、図１（ｃ）の拡大図に示すように、軒天係合用凹部４ｂの開口部の途中では、軒天井材２０の厚みよりも若干狭くなっており、軒天井材２０と嵌合するときに間隔が広げられ、それによって生じるバネ力によって、凹部６ｂと軒天井材２０の嵌合を強化することができる。ただし、軒天係合用凹部４ｂの先端部は、軒天井材２０の厚みよりも若干広くなっており、化粧板部分２を下地材に当接させたときに、軒天井材２０が凹部６ｂにスムーズに挿入されるようになっている。   Further, the eaves-top engaging recess 4b at the right end is provided at a position where the eaves-ceiling member 2 and the base material 50 are brought into contact with the eaves ceiling material 20. The opening of the eaves-engagement recess 4b is formed to have a size corresponding to the thickness of the eaves ceiling material 20, but as shown in the enlarged view of FIG. In the middle of the part, it is slightly narrower than the thickness of the eaves ceiling material 20, and the interval is widened when mated with the eaves ceiling material 20, and the spring force generated thereby causes the recess 6 b and the eaves ceiling material 20 to be fitted. Can be strengthened. However, the front end of the eaves-top engaging recess 4b is slightly wider than the eaves ceiling material 20, and when the decorative board portion 2 is brought into contact with the base material, the eaves ceiling material 20 becomes the recess 6b. It is designed to be inserted smoothly.

以上のように、化粧板部分２と換気材部分４が充分な強度を持って接続されて換気化粧部材１を形成し、その状態で化粧板部分２を下地材５０に当接させることによって、換気材部分４の先端にある軒天係合用凹部４ｂと軒天井材２０を嵌合させる。この嵌合により軒天係合用凹部４ｂと軒天井材２０とが固定され、化粧板部分２を下地材に固定することによって、換気構造を有する軒天井裏を形成することができる。なお、換気材部分４の軒天係合用凹部４ｂと軒天井材２０の嵌合を更に強固にするため、ネジ等の固定部品や接着剤等を用いることもできる。   As described above, the decorative board part 2 and the ventilation material part 4 are connected with sufficient strength to form the ventilation decorative member 1, and in this state, the decorative board part 2 is brought into contact with the base material 50, The eaves-top engaging recess 4b and the eaves ceiling member 20 at the tip of the ventilation material part 4 are fitted. By this fitting, the eaves-top engaging recess 4b and the eaves ceiling material 20 are fixed, and the eaves ceiling back having a ventilation structure can be formed by fixing the decorative plate portion 2 to the base material. In addition, in order to further strengthen the fitting between the eaves-top engaging recess 4b of the ventilation material portion 4 and the eaves ceiling material 20, a fixing part such as a screw, an adhesive, or the like can be used.

本実施形態では、化粧板部分２は窯業系材料又は樹脂材料からなるので、装飾性の高い多彩な色彩、模様、形状を有することができ、また、施工現場で部材を削って調整をすることも容易に行なうことができる。また、換気材部分４は金属材料からなるので、長期間使用しても破損が少なく、換気口が詰まってもメンテナンスが容易であり、更に、バネ力による強い嵌合を実現することができる。
なお、化粧板部分２や換気材部分４の材料としては、本実施形態に限られるものではなく、用途に応じて、あらゆる材料を適用することができる。 In this embodiment, since the decorative board portion 2 is made of a ceramic material or a resin material, the decorative board portion 2 can have various colors, patterns, and shapes with high decorativeness, and can be trimmed and adjusted at the construction site. Can also be done easily. Further, since the ventilation material portion 4 is made of a metal material, it is less damaged even when used for a long period of time, is easy to maintain even if the ventilation port is clogged, and can realize a strong fitting by a spring force.
In addition, as a material of the decorative board part 2 and the ventilation material part 4, it is not restricted to this embodiment, All materials can be applied according to a use.

The construction (attachment, removal) method of the ventilation decorative member shown in FIG. 5 will be described with reference to FIGS. 6 and 7 are also side sectional views as seen from the arrow A in FIG.
First, a method for attaching the ventilation decorative member 1 shown in FIG. 5 will be described with reference to FIG. First, as shown in FIG. 6A, the recess 6a ′ of the decorative board portion 2 and the convex portion 6b ′ of the ventilation material portion 4 are fitted to connect the decorative board portion 2 and the ventilation material portion 4. The ventilation decorative member 1 is formed. At this time, a bracket 8 is attached to the ventilation material portion 4 by a screw component 10 in advance.
The connecting operation of the decorative board part 2 and the ventilation material part 4 is usually performed on the ground of the construction site, and the ventilation decorative member 1 to which the decorative board part 2 and the ventilation material part 4 are connected is carried to the position of the attic. Then, as shown in FIG. 6B, first, the ventilation decorative member 1 is lifted up to a position where the decorative plate portion 2 faces the base material 50, and then the decorative plate portion 2 is in contact with the base material 50. Then, the ventilation decorative member 1 is moved horizontally from the left side to the right side. By this movement, the eaves ceiling part 20 is inserted into the opening part of the eaves top engaging recess 4b at the tip of the ventilation material part 4 connected to the decorative board part 2.

そして、図６（ｃ）に示すように、軒天係合用凹部４ｂと軒天井材２０とが嵌合により固定されているので、スクリュー釘１２を用いて化粧板部分２を下地材５０に固定することによって、換気構造を有する軒天井裏を形成することができる。なお、軒天係合用凹部４ｂと軒天井部２０の嵌合部分については、ネジ等の固定部品を用いて補強することもできる。   Then, as shown in FIG. 6C, since the eaves-top engaging recess 4b and the eaves ceiling material 20 are fixed by fitting, the decorative board portion 2 is fixed to the base material 50 using the screw nails 12. By doing so, an eaves ceiling with a ventilation structure can be formed. In addition, about the fitting part of the recessed part 4b for eaves-top engagement, and the eaves ceiling part 20, it can also reinforce using fixing components, such as a screw | thread.

化粧板部分２と換気材部分４が接続された換気化粧部材１を屋根裏に取り付けた後、ある期間が経過すると、破損や換気口４ａの詰まり等により、換気材部分４を交換しなければならない事態が生じる場合が多い。この場合、図５に示す換気化粧部材１では、化粧板部分２を下地材５０に取り付けたまま、換気材部分４だけを交換することができる。   After a certain period of time has passed after attaching the ventilation decorative member 1 to which the decorative plate portion 2 and the ventilation material portion 4 are connected to the attic, the ventilation material portion 4 must be replaced due to damage, clogging of the ventilation opening 4a, or the like. Things often happen. In this case, in the ventilation decorative member 1 shown in FIG. 5, only the ventilation material portion 4 can be replaced while the decorative plate portion 2 is attached to the base material 50.

次に、この換気材部分４の交換の方法を、図７を用いて説明する。まず、図７（ａ）に示すように、ネジ部品１０を取り外し、ブラケット８を換気材部分４から取り外す。次に、図７（ｂ）に示すように、換気材部分４を上方へ持ち上げて、凹部６ａ’と凸部６ｂ’の嵌合をはずし、更に、換気材部分４を垂直に立てながら、紙面斜め右上方へ持ち上げる。   Next, a method for replacing the ventilation material portion 4 will be described with reference to FIG. First, as shown to Fig.7 (a), the screw component 10 is removed and the bracket 8 is removed from the ventilation material part 4. FIG. Next, as shown in FIG. 7 (b), the ventilation material portion 4 is lifted upward to disengage the concave portion 6 a ′ and the convex portion 6 b ′. Lift up diagonally to the upper right.

換気材部分４を持ち上げる方法としては、下方から持ち上げることも可能であるし、軒天井内に吊り上げ治具を設置できる場合には、その吊り上げ治具を用いて、上方から換気材部分４を吊り上げることもできる。そして、図７（ｃ）に示すように、換気材部分４をほぼ垂直に立てて、下地材５０と軒天井材２０との間のスペースを通過させて、地上へ下ろすことができる。   As a method of lifting the ventilation material part 4, it is possible to lift from below, and when a lifting jig can be installed in the eaves ceiling, the ventilation material part 4 is lifted from above using the lifting jig. You can also. And as shown in FIG.7 (c), the ventilation material part 4 can be stood substantially perpendicularly, the space between the base material 50 and the eaves ceiling material 20 can be passed, and it can drop to the ground.

そして、新たな換気材部分４を、上記の図７（ａ）〜（ｃ）の手順の逆を行なうことによって、元の位置に取り付けることができる。つまり、ブラケット８の取り付けられていない換気材部分４を、ほぼ垂直な状態で持ち上げて、下地材５０と軒天井材２０との間のスペースを通過させて、軒天井裏へ入れる。そして、換気材部分４を水平にしながら紙面斜め左下方へ移動させ、換気材部分４の凸部６ｂ’を、化粧板部分２の凹部６ａ’の中へ落とし込んで嵌合させる。そして、ネジ部品１０を用いて、ブラケット８を換気材部分４を取り付けることにより、換気材部分４が軒天井材２０に固定され、元の換気構造を有する軒天井裏を形成することができる。以上の施工方法によって、換気材部分４の交換に要する費用を低減させることができる。   And the new ventilation material part 4 can be attached to the original position by performing the reverse of the procedure of said FIG. 7 (a)-(c). That is, the ventilation material portion 4 to which the bracket 8 is not attached is lifted in a substantially vertical state, and is allowed to pass through the space between the base material 50 and the eaves ceiling material 20 and enter the eaves ceiling. Then, the ventilation material portion 4 is moved to the lower left oblique direction while being horizontal, and the convex portion 6 b ′ of the ventilation material portion 4 is dropped into the concave portion 6 a ′ of the decorative board portion 2 to be fitted. And the ventilation material part 4 is fixed to the eaves ceiling material 20 by attaching the ventilation material part 4 to the bracket 8 using the screw component 10, and the eaves ceiling back which has the original ventilation structure can be formed.
