Description

本発明は、住宅等の建築物における外壁材の取付構造及び外壁材の取付方法に関するものである。 The present invention relates to an outer wall material mounting structure and an outer wall material mounting method in a building such as a house.

従来、住宅等の建築物において、外壁材３（サイディング）は図４及び図５に示すようにして取り付けられていた。すなわち、複数の柱１を離間させて立設し、透湿防水シート１１を挟んで、各柱１に外壁下地材２（縦胴縁）を取り付ける。このとき透湿防水シート１１の屋内側には断熱材１２を設置する。そして、複数の外壁材３を隣接させると共に、各外壁材３を外壁下地材２に固定具４で取り付けるようにしていた。 Conventionally, in a building such as a house, the outer wall material 3 (siding) is attached as shown in FIGS. 4 and 5. That is, the plurality of pillars 1 are set up separately, and the outer wall base material 2 (vertical trunk edge) is attached to each pillar 1 with the moisture permeable waterproof sheet 11 interposed therebetween. At this time, a heat insulating material 12 is installed on the indoor side of the moisture permeable waterproof sheet 11. The plurality of outer wall materials 3 are adjacent to each other, and each outer wall material 3 is attached to the outer wall base material 2 with a fixture 4.

ここで、外壁材３を隣接させると目地溝６が形成されるが、防水性を確保する必要があるため、この目地溝６はいわゆるハット型のジョイナー７を用いて図６に示すようにして閉塞していた（例えば、特許文献１〜３参照。）。すなわち、まずジョイナー７のフランジ部３０を外壁下地材２の屋外側の面に密着させることによってジョイナー７を外壁下地材２に取り付け、次にジョイナー７の突出部３１を挟んで外壁材３を設置することによって目地溝６を形成する。そして、この目地溝６にシーリング材８を充填することによって、目地溝６を閉塞するようにしていた。
特開２００４−６８４６４号公報特開平９−２５６４９３号公報特開２００２−８８９３５号公報 Here, when the outer wall material 3 is made adjacent, a joint groove 6 is formed. However, since it is necessary to ensure waterproofness, the joint groove 6 is formed using a so-called hat-type joiner 7 as shown in FIG. (For example, refer patent documents 1-3). That is, first, the joiner 7 is attached to the outer wall base material 2 by bringing the flange portion 30 of the joiner 7 into close contact with the outdoor side surface of the outer wall base material 2, and then the outer wall material 3 is installed with the protrusion 31 of the joiner 7 sandwiched therebetween. By doing so, the joint groove 6 is formed. The joint grooves 6 are filled with a sealing material 8 so as to close the joint grooves 6.

しかしながら、建築物の構造等によっては柱１と柱１の間隔は異なる場合があるので、このような場合には外壁材３を端から順に隣接して取り付けていくと、外壁材３の側端が柱１と柱１の間に位置してしまうこととなる（図４の破線部分参照）。そうすると、上述したような方法では目地溝６を閉塞することができなくなる。なぜなら、ジョイナー７を取り付ける外壁下地材２が柱１と柱１の間には存在しないからである。よって、このような場合には、外壁下地材２が存在する場所に外壁材３の側端が位置するように、外壁材３の大きさを調整すべく、施工現場において外壁材３を切断しなければならない。また、あらかじめ工場において外壁材３の側縁を丁寧に加工処理していても、上記のように切断すると、施工現場において改めて加工処理する必要性が生じる。そして、切断により生じた外壁材３の切断片３３（図４の破線部分）は、中途半端なサイズであるため再利用することができず、廃棄せざるを得なかった。 However, since the interval between the pillars 1 and 1 may be different depending on the structure of the building, in such a case, if the outer wall material 3 is attached adjacently in order from the end, the side edge of the outer wall material 3 Will be located between the pillar 1 and the pillar 1 (refer the broken-line part of FIG. 4). Then, the joint groove 6 cannot be closed by the method as described above. This is because the outer wall base material 2 to which the joiner 7 is attached does not exist between the pillars 1 and 1. Therefore, in such a case, the outer wall material 3 is cut at the construction site in order to adjust the size of the outer wall material 3 so that the side end of the outer wall material 3 is located where the outer wall base material 2 exists. There must be. Moreover, even if the side edge of the outer wall material 3 is carefully processed in advance in the factory, if it is cut as described above, it becomes necessary to process it again at the construction site. Then, the cut piece 33 (broken line portion in FIG. 4) of the outer wall material 3 generated by the cutting cannot be reused because it has a halfway size, and must be discarded.

本発明は上記の点に鑑みてなされたものであり、柱と柱の間隔が異なる場合があっても、外壁材を切断することなく取り付けることができ、施工現場における作業の効率化を図ることができると共に、材料ロスの発生を防止することができる外壁材の取付構造及び外壁材の取付方法を提供することを目的とするものである。 The present invention has been made in view of the above points, and even if the interval between the columns may be different, the outer wall material can be attached without cutting, and work efficiency at the construction site is improved.

以下、本発明の実施の形態を説明する。 Embodiments of the present invention will be described below.

図１及び図２は本発明に係る外壁材の取付構造の一例を示すものである。この例では、まず、複数の柱１を離間して立設し、各柱１の屋外側に透湿防水シート１１を張設すると共にこの透湿防水シート１１を挟んで、各柱１の屋外側の面に外壁下地材２（縦胴縁）を取り付ける。このとき、透湿防水シート１１の屋内側であって柱１と柱１の間には、断熱材１２を設置する。ここで、上記柱１には間柱も含まれる。また、透湿防水シート１１及び断熱材１２は従来と同様のものを用いることができ、さらに、各柱１への外壁下地材２の取付は従来と同様に行うことができる。なお、複数の柱１は、例えば、４５５ｍｍ又は５００ｍｍのピッチで離間して立設することができるが、これに限定されるものではない。 1 and 2 show an example of an outer wall material mounting structure according to the present invention. In this example, first, a plurality of pillars 1 are spaced apart and a moisture permeable waterproof sheet 11 is stretched on the outdoor side of each pillar 1 and the moisture permeable waterproof sheet 11 is sandwiched between the pillars 1 to The outer wall base material 2 (vertical trunk edge) is attached to the outer surface. At this time, a heat insulating material 12 is installed between the pillar 1 and the pillar 1 on the indoor side of the moisture-permeable waterproof sheet 11. Here, the pillar 1 includes an inter-column. Moreover, the moisture-permeable waterproof sheet 11 and the heat insulating material 12 can use the same thing as the past, and also the attachment of the outer wall base material 2 to each pillar 1 can be performed similarly to the past. In addition, although the some pillar 1 can be standingly spaced apart with a pitch of 455 mm or 500 mm, for example, it is not limited to this.

次に、外壁下地材２，２間に下地用横架材５を架け渡して設ける。下地用横架材５としては、図３（ａ）（ｂ）に示すようなものを用いることができる。いずれの下地用横架材５もステンレスやメッキ鋼板等の平板を折り曲げ加工することによって容易に作製することができる。 Next, the base horizontal member 5 is provided between the outer wall base materials 2 and 2. As the foundation horizontal member 5, the one shown in FIGS. 3A and 3B can be used. Any of the base horizontal members 5 can be easily manufactured by bending a flat plate such as stainless steel or a plated steel plate.

図３（ａ）に示す下地用横架材５は、外壁下地材２，２間に架け渡す際に略水平となる長尺状の平板部１３と、平板部１３の長手方向に沿った一側縁から垂設された外壁材取付片１４と、平板部１３の長手方向の両端部から垂設された２つの固定用突片１５とで構成されている。平板部１３の長手方向の長さは、下地用横架材５が架け渡される一組の外壁下地材２，２の対向面間の距離に略等しい。また、２つの固定用突片１５には外壁下地材２に固定するためのビス１６等を通す通孔１７が穿設されている。 3 (a) includes a long flat plate portion 13 that is substantially horizontal when it is bridged between the outer wall base materials 2 and 2, and a long plate member 13 along the longitudinal direction of the flat plate portion 13. The outer wall member mounting piece 14 is suspended from the side edge, and the two fixing protrusions 15 are suspended from both longitudinal ends of the flat plate portion 13. The length in the longitudinal direction of the flat plate portion 13 is substantially equal to the distance between the opposing surfaces of the pair of outer wall base materials 2 and 2 on which the base horizontal member 5 is bridged. The two fixing protrusions 15 are provided with through holes 17 through which screws 16 and the like for fixing to the outer wall base material 2 are passed.

一方、図３（ｂ）に示す下地用横架材５も、上記と同様に平板部１３と外壁材取付片１４と２つの固定用突片１５とで構成されているが、平板部１３には複数の通気孔９が穿設されており、さらに、２つの固定用突片１５には離間する向きにそれぞれ位置固定用舌片１０が垂設されている。これら２つの位置固定用舌片１０が形成する面と外壁材取付片１４が形成する面とは略面一となっている。 On the other hand, the base horizontal member 5 shown in FIG. 3B is also composed of the flat plate portion 13, the outer wall material mounting piece 14, and the two fixing protrusions 15 as described above. A plurality of ventilation holes 9 are formed, and further, position fixing tongues 10 are vertically suspended from the two fixing protrusions 15 so as to be separated from each other. The surface formed by these two position fixing tongue pieces 10 and the surface formed by the outer wall material attaching piece 14 are substantially flush with each other.

本発明においては、上記いずれの下地用横架材５も用いることができるが、図３（ａ）に示すものよりも、図３（ｂ）に示すものを用いる方がより好ましいので、以下では、図３（ｂ）に示す下地用横架材５を用いた例について説明する。 In the present invention, any of the above-mentioned base horizontal members 5 can be used, but it is more preferable to use the one shown in FIG. 3B than the one shown in FIG. An example using the underlaying horizontal member 5 shown in FIG. 3B will be described.

外壁下地材２，２間に下地用横架材５を架け渡すにあたっては、まず、下地用横架材５の平板部１３を略水平にすると共に外壁材取付片１４を屋外側に向けて、屋外側から屋内側へ下地用横架材５を外壁下地材２，２間に差し入れるようにする。そうすると、図１に示すように、下地用横架材５の両端部に延設された位置固定用舌片１０がそれぞれ外壁下地材２の屋外側の面に当接して引っ掛かり、これにより、屋外側から屋内側への方向における位置決めを容易かつ迅速に行うことができるものである。そして、下地用横架材５を架け渡す高さを調整した後、２つの固定用突片１５の通孔１７にビス１６等を通して、下地用横架材５を外壁下地材２，２間において固定する。なお、下地用横架材５は、一組の外壁下地材２，２間の上下方向において複数架け渡して設けることができる。また、下地用横架材５は、隣接する外壁材３，３によって形成される目地溝６が一組の外壁下地材２，２の間に位置してしまうような場合において、これらの外壁下地材２，２間に架け渡して設ければよいのであって、必ずしもすべての外壁下地材２，２間に架け渡して設ける必要はない。 In laying the base horizontal member 5 between the outer wall base materials 2 and 2, first, the flat plate portion 13 of the base horizontal member 5 is made substantially horizontal and the outer wall member attachment piece 14 is directed to the outdoor side. The base horizontal member 5 is inserted between the outer wall base materials 2 and 2 from the outdoor side to the indoor side. Then, as shown in FIG. 1, the position fixing tongues 10 extending at both ends of the base horizontal member 5 are brought into contact with and caught by the outdoor side surface of the outer wall base material 2, thereby Positioning in the direction from the outside to the indoor side can be performed easily and quickly. Then, after adjusting the height over which the base horizontal member 5 is bridged, the base horizontal member 5 is placed between the outer wall base materials 2 and 2 by passing screws 16 or the like through the through holes 17 of the two fixing protrusions 15. Fix it. Note that a plurality of base horizontal members 5 can be provided across the pair of outer wall base materials 2 and 2 in the vertical direction. In addition, the horizontal member 5 for the base is used when the joint groove 6 formed by the adjacent outer wall materials 3 and 3 is located between the pair of outer wall base materials 2 and 2. It suffices to provide a bridge between the materials 2 and 2, and it is not always necessary to provide a bridge between all the outer wall base materials 2 and 2.

次に、複数の外壁材３を隣接させて外壁下地材２に固定具４で取り付ける。固定具４は、従来の留め金具１８及び留め金具用ビス１９からなるものを用いることができる。このような固定具４で、図１に示すように外壁材３の上辺を固定するものであり、また、図示省略しているが、外壁材３の下辺を支持して固定するものである。 Next, a plurality of outer wall materials 3 are adjacent to each other and attached to the outer wall base material 2 with a fixture 4. The fixture 4 may be a conventional fastener 18 and a fastener screw 19. With such a fixture 4, as shown in FIG. 1, the upper side of the outer wall material 3 is fixed, and although not shown, the lower side of the outer wall material 3 is supported and fixed.

外壁材３を上下方向に取り付けていく場合には、下に設置される外壁材３の上辺に設けた雄実部２０が、上に設置される外壁材３の下辺に設けた雌実部２１に挿入されることとなる。これにより、雨水等の浸入を防止し、防水性を確保することができる。 When the outer wall material 3 is attached in the vertical direction, the male part 20 provided on the upper side of the outer wall material 3 installed below is the female part 21 provided on the lower side of the outer wall material 3 installed on the upper side. Will be inserted. This prevents infiltration of rain water or the like, it is possible to ensure the waterproof property.

外壁材３を左右方向に取り付けていく場合には、隣接する外壁材３，３によって形成される目地溝６は、図６に示すものと同様に、湿式タイプの目地材２２により閉塞する。この目地材２２は、外壁材３の裏面側に配置されるジョイナー７と、外壁材３の表面側に充填して配置されるシーリング材８とで構成される。ジョイナー７としては、湿式タイプ用のものであれば特に限定されるものではないが、例えば、ハット型のジョイナー７等を用いることができる。以下では、便宜上、ジョイナー７としてハット型のものを用いる場合について説明する。ハット型ジョイナー７は、図１に示すように、長尺状で断面略コ字状の突出部３１と、突出部３１の両側縁から離間する向きにそれぞれ垂設されたフランジ部３０，３０とによって構成されている。一方、シーリング材８は、従来と同様のものを用いることができる。上記のような目地材２２により、隣接する外壁材３，３によって形成される目地溝６を閉塞するにあたっては、次のようにして行う。すなわち、まず、図６に示すように、ハット型ジョイナー７のフランジ部３０を外壁下地材２の屋外側の面に密着させることによってハット型ジョイナー７を外壁下地材２に取り付け、次にハット型ジョイナー７の突出部３１を挟んで外壁材３，３を設置することによって目地溝６を形成する。そして、隣接する外壁材３，３の側面とハット型ジョイナー７の突出部３１とで形成される目地溝６にシーリング材８を注入して充填することによって、目地溝６を閉塞することができる。 When the outer wall material 3 is attached in the left-right direction, the joint groove 6 formed by the adjacent outer wall materials 3 and 3 is blocked by the wet type joint material 22 as shown in FIG. The joint material 22 includes a joiner 7 disposed on the back surface side of the outer wall material 3 and a sealing material 8 disposed so as to be filled on the front surface side of the outer wall material 3. The joiner 7 is not particularly limited as long as it is for a wet type. For example, a hat-type joiner 7 or the like can be used. Below, the case where a hat-type thing is used as the joiner 7 is demonstrated for convenience. As shown in FIG. 1, the hat-type joiner 7 has a long and substantially U-shaped protrusion 31, and flanges 30 and 30 that are vertically suspended from both side edges of the protrusion 31. It is constituted by. On the other hand, the sealing material 8 can be the same as the conventional one. When the joint groove 6 formed by the adjacent outer wall materials 3 and 3 is closed with the joint material 22 as described above, the following operation is performed. That is, first, as shown in FIG. 6, the hat-type joiner 7 is attached to the outer wall base material 2 by bringing the flange portion 30 of the hat-type joiner 7 into close contact with the outdoor side surface of the outer wall base material 2, and then the hat type The joint groove 6 is formed by installing the outer wall materials 3 and 3 with the protruding portion 31 of the joiner 7 interposed therebetween. Then, the joint groove 6 can be closed by injecting and filling the sealing material 8 into the joint groove 6 formed by the side surfaces of the adjacent outer wall members 3 and 3 and the protrusion 31 of the hat-type joiner 7. .

上記のように、ハット型ジョイナー７は、通常、外壁下地材２に取り付けられるものであるが、本発明においては、外壁下地材２，２間に下地用横架材５を設けているため、この下地用横架材５にもハット型ジョイナー７を取り付けることができる。よって、外壁材３の側端が、図１に示すように、柱１と柱１の間（つまり、外壁下地材２と外壁下地材２との間）に位置するようになっても構わない。すなわち、この場合には、図１に示すように、ハット型ジョイナー７のフランジ部３０を下地用横架材５の外壁材取付片１４にビス２８等を用いて取り付け、次にハット型ジョイナー７の突出部３１を挟んで外壁材３を設置することによって目地溝６を形成する。そして、この目地溝６にシーリング材８を注入して充填することによって、目地溝６を閉塞することができる。このように、外壁材３を端から順に隣接して取り付けていく場合において、目地溝６がどのような位置に形成されても、この目地溝６の位置に合わせて下地用横架材５又は外壁下地材２にハット型ジョイナー７を取り付けると共に、シーリング材８を充填することによって目地溝６を閉塞することができる。したがって、柱１と柱１の間隔が異なる場合があっても、外壁材３を切断することなく取り付けることができ、施工現場における作業の効率化を図ることができると共に、材料ロスを削減することができるものである。なお、下地用横架材５の外壁材取付片１４にはハット型ジョイナー７のみならず、図１に示すように、外壁材３を取り付けるための留め金具１８及び留め金具用ビス１９からなる固定具４も取り付けることができる。よって、これにより、外壁材３の取付強度をさらに高めることができるものである。 As described above, the hat-type joiner 7 is normally attached to the outer wall base material 2, but in the present invention, the base horizontal member 5 is provided between the outer wall base materials 2 and 2, A hat-type joiner 7 can also be attached to the base horizontal member 5. Therefore, as shown in FIG. 1, the side end of the outer wall material 3 may be positioned between the pillars 1 and 1 (that is, between the outer wall base material 2 and the outer wall base material 2). . That is, in this case, as shown in FIG. 1, the flange portion 30 of the hat-type joiner 7 is attached to the outer wall material attachment piece 14 of the base horizontal member 5 using screws 28 or the like, and then the hat-type joiner 7. The joint groove 6 is formed by installing the outer wall material 3 with the protruding portion 31 therebetween. And the joint groove | channel 6 can be obstruct | occluded by inject | pouring and filling the sealing material 8 in this joint groove | channel 6. FIG. Thus, when attaching the outer wall material 3 in order adjacent to each other from the end, regardless of the position where the joint groove 6 is formed, the base horizontal member 5 or the base groove material 5 is matched to the position of the joint groove 6. The joint groove 6 can be closed by attaching the hat type joiner 7 to the outer wall base material 2 and filling the sealing material 8. Therefore, even if the distance between the pillar 1 and the pillar 1 may be different, the outer wall material 3 can be attached without cutting, work efficiency at the construction site can be improved, and material loss can be reduced. It is something that can be done. It should be noted that the outer wall member attachment piece 14 of the base horizontal member 5 is fixed not only with the hat type joiner 7 but also with a fastener 18 for attaching the outer wall member 3 and a fastener screw 19 as shown in FIG. A tool 4 can also be attached. Therefore, this makes it possible to further increase the mounting strength of the outer wall material 3.

また、外壁下地材２，２間に下地用横架材５を架け渡して設けると、この下地用横架材５の存在によって、上下方向の通気が悪くなるおそれがあるが、下地用横架材５として、図３（ａ）に示すものではなく図３（ｂ）に示すもののように、上下に貫通する通気孔９が穿設されたものを用いると、図１に示すようにこの通気孔９によって、上下方向における通気性が良くなり、結露を防止することができるものである。 In addition, if the base horizontal member 5 is provided between the outer wall base materials 2 and 2, the presence of the base horizontal member 5 may deteriorate the ventilation in the vertical direction. If the material 5 is not shown in FIG. 3 (a), but is provided with a vent hole 9 penetrating vertically like the one shown in FIG. 3 (b), this passage is shown in FIG. The air holes 9 improve air permeability in the vertical direction and can prevent condensation.
