Description
本発明は、外壁部材を支持するための外壁部材の支持具に関する。 The present invention relates to a support for an outer wall member for supporting the outer wall member.
特許文献１には、縦片と、当該縦片の一端に当該縦片に対して垂直方向に突出するよう設けられた横片と、を備える外壁部材の支持具が記載されている。当該支持具は、水切り材を介して建物躯体に取り付けられた胴縁に、縦片が取り付け固定された状態で、横片に外壁部材の下端を載置するように構成されている。 Patent Document 1 describes a support for an outer wall member including a vertical piece and a horizontal piece provided at one end of the vertical piece so as to project in a direction perpendicular to the vertical piece. The support is configured so that the lower end of the outer wall member is placed on the horizontal piece in a state where the vertical piece is attached and fixed to the furring strip attached to the building frame via the drainer.
当該支持具では、縦片および横片の先端部を外壁部材が載置される側となる内側へ折り返して折り返し部を構成し、当該折り返し部に外壁部材を当接させて支持する構成である。このため、外壁部材と縦片および横片との間に隙間が形成されて、外壁部材と支持具との間に侵入した雨水や結露水を効率よく排出することができる。 In the support tool, the tip portions of the vertical piece and the horizontal piece are folded back inward on the side on which the outer wall member is placed to form a folded portion, and the outer wall member is brought into contact with the folded portion to support the support. .. Therefore, a gap is formed between the outer wall member and the vertical piece and the horizontal piece, and rainwater or condensed water that has entered between the outer wall member and the support can be efficiently discharged.
ところで、近年、省資源、低価格の観点から胴縁を省略する工法が採用される場合がある。この場合、支持具は、水切り材を介して直接建物躯体に取り付け固定される。しかし、上述した支持具では、縦片が平板状であるため、水切り材を建物躯体に取り付け固定する釘やネジなどの頭部等から構成される突出部に縦片が乗り上げ、支持具が建物躯体に対して傾いた状態で取り付けられる場合がある。 By the way, in recent years, a construction method that omits the furring strip may be adopted from the viewpoint of resource saving and low price. In this case, the support is directly attached and fixed to the building frame via the drainer. However, in the above-mentioned support, since the vertical piece is flat, the vertical piece rides on the protruding portion composed of the heads such as nails and screws that attach and fix the drainer to the building frame, and the support is the building. It may be installed in a tilted state with respect to the skeleton.
また、上述した支持具では、縦片の先端部が折り返されているため、縦片の先端位置を作業者が目視により確認することが困難となる。このため、建物躯体に記した支持具取り付け用の基準線（墨出し線）に当該縦片を合わせ難く、支持具を建物躯体の所定の位置に精度よく取り付けることが困難となる。 Further, in the support tool described above, since the tip end portion of the vertical piece is folded back, it is difficult for the operator to visually confirm the tip position of the vertical piece. For this reason, it is difficult to align the vertical piece with the reference line (inking line) for attaching the support, which is written on the building skeleton, and it is difficult to accurately attach the support to a predetermined position on the building skeleton.
本発明は、上記に鑑みてなされたものであり、胴縁を用いることなく水切り材を介して支持具を建物躯体に取付ける場合において、当該支持具が建物躯体に対して傾いた状態で取り付けられることを防止できる支持具を提供することを目的の一つとする。 The present invention has been made in view of the above, and when the support is attached to the building skeleton via a drainer without using the furring strip, the support is attached in a state of being tilted with respect to the building skeleton.

As shown in FIG. 1, the concave groove portion 24 is continuously provided over the entire area of the starter metal fitting 1 in the longitudinal direction. As a result, the bending rigidity of the starter metal fitting 1 itself can be improved.
さらに、凹溝部２４の大きさ、即ち、図２における上下方向及び左右方向の幅は、水切り材８０を土台５０に取り付ける際に想定されるネジ９２の頭部９２ａを包囲するのに十分な大きさに設定されている。 Further, the size of the concave groove portion 24, that is, the width in the vertical direction and the horizontal direction in FIG. 2, is large enough to surround the head 92a of the screw 92 which is assumed when the drainer 80 is attached to the base 50. It is set to.
横片４は、図２に示すように、基部４２と、折曲部４４と、から構成されている。基部４２は、下側平板部２２ｂの下端から連続して設けられ、下側平板部２２ｂとのなす角が略直角となるように構成されている。また、基部４２には、図３に示すように、スタータ金具１の長手方向に沿って複数の通気穴４０が形成されている。 As shown in FIG. 2, the horizontal piece 4 is composed of a base portion 42 and a bent portion 44. The base portion 42 is continuously provided from the lower end of the lower flat plate portion 22b, and is configured such that the angle formed by the lower flat plate portion 22b is substantially a right angle. Further, as shown in FIG. 3, a plurality of ventilation holes 40 are formed in the base portion 42 along the longitudinal direction of the starter metal fitting 1.
なお、基部４２の延出方向の長さは、本実施形態では、基部４２に後述する外壁部材７０を支持した状態において、外壁部材７０が凹溝部２４に当接しない程度の長さに設定されている。 In the present embodiment, the length of the base portion 42 in the extending direction is set to such a length that the outer wall member 70 does not come into contact with the concave groove portion 24 when the outer wall member 70 described later is supported by the base portion 42. ing.
折曲部４４は、基部４２の端部を上方に折り曲げることにより構成されている。折曲部４４は、基部４２とのなす角が鈍角となるように構成されている。 The bent portion 44 is configured by bending the end portion of the base portion 42 upward. The bent portion 44 is configured such that the angle formed by the bent portion 44 with the base portion 42 is an obtuse angle.
次に、こうして構成されたスタータ金具１を用いた外壁部材７０の施工について説明する。なお、本実施形態では、外壁部材７０の長手方向が水平方向となるように外壁部材７０を取り付ける横張り工法による施工の場合を説明する。 Next, the construction of the outer wall member 70 using the starter metal fitting 1 thus configured will be described. In this embodiment, the case of the horizontal construction method in which the outer wall member 70 is attached so that the longitudinal direction of the outer wall member 70 is the horizontal direction will be described.
まず、図４および図５に示すように、コンクリートで形成された基礎６０の上端にアンカーボルト等（図示せず）によって取り付け固定された土台５０の屋外側（図４および図５の左側）の面に、水切り材８０をネジ９２を用いて取り付け固定する。水切り材８０は、当該水切り材８０を土台５０に水平に取り付けるために当該土台５０の屋外側の面に記した基準線（墨出し線）に合わせて取り付けられる。 First, as shown in FIGS. 4 and 5, the outdoor side (left side of FIGS. 4 and 5) of the foundation 50 attached and fixed to the upper end of the foundation 60 made of concrete by anchor bolts or the like (not shown). The drainer 80 is attached and fixed to the surface using screws 92. The drainer 80 is attached along the reference line (inking line) marked on the outdoor side surface of the base 50 in order to attach the drainer 80 horizontally to the base 50.
次に、土台５０および当該土台５０に立設された図示しない柱材に対して屋外側（図４および図５の左側）から防水紙８２をステープル等で貼り付ける。なお、この際、防水紙８２は張った状態となるよう貼り付けることが望ましく、また、防水紙８２と水切り材８０とを両面防水テープ等を用いて接着しておくことが望ましい。 Next, the waterproof paper 82 is attached to the base 50 and the pillars (not shown) erected on the base 50 from the outdoor side (left side of FIGS. 4 and 5) with staples or the like. At this time, it is desirable that the waterproof paper 82 is attached so as to be in a stretched state, and it is desirable that the waterproof paper 82 and the drainer 80 are adhered to each other using a double-sided waterproof tape or the like.
続いて、スタータ金具１の上側平板部２２ａに設けた貫通穴１３にスタータ固定ネジ９４を挿通し、スタータ金具１の平板部２２と土台５０との間に防水紙８２および水切り材８０を挟んだ状態で、当該スタータ固定ネジ９４をねじ込むことによりスタータ金具１を土台５０に仮固定する。スタータ固定ネジ９４は、「締結部材」の一例である。 Subsequently, the starter fixing screw 94 was inserted into the through hole 13 provided in the upper flat plate portion 22a of the starter metal fitting 1, and the waterproof paper 82 and the drainer 80 were sandwiched between the flat plate portion 22 of the starter metal fitting 1 and the base 50. In this state, the starter metal fitting 1 is temporarily fixed to the base 50 by screwing the starter fixing screw 94. The starter fixing screw 94 is an example of a “fastening member”.
そして、スタータ金具１の上端部、即ち、上側平板部２２ａの上端が、スタータ金具１を土台５０に水平に取り付けるために防水紙８２の屋外側の面に記した基準線（墨出し線）に合うようにスタータ金具１を上下移動させながら位置合わせして水平になった時点でスタータ固定ネジ９４の本締めを行う。さらに貫通穴１２にもスタータ固定ネジ９４を挿通してスタータ金具１の土台５０への取り付け固定を完了する。 Then, the upper end portion of the starter metal fitting 1, that is, the upper end portion of the upper flat plate portion 22a, forms a reference line (inking line) marked on the outdoor side surface of the waterproof paper 82 in order to horizontally attach the starter metal fitting 1 to the base 50. The starter fixing screw 94 is finally tightened when the starter metal fitting 1 is aligned and leveled while being moved up and down so as to match. Further, the starter fixing screw 94 is also inserted into the through hole 12 to complete the attachment and fixing of the starter metal fitting 1 to the base 50.
ここで、スタータ金具１の縦片２の上端、即ち、上側平板部２２ａの上側の部材端のままの上端が、水平面を有する直角な断面となっているため、上側平板部２２ａの上端を目視により確認し易い。このため、作業者は、上述した基準線（墨出し線）にスタータ金具１を位置合わせし易く、スタータ金具１を土台５０に対して精度よく水平に取り付けることができる。 Here, since the upper end of the vertical piece 2 of the starter metal fitting 1, that is, the upper end of the upper flat plate portion 22a as the upper end of the member has a right-angled cross section having a horizontal plane, the upper end of the upper flat plate portion 22a is visually observed. Easy to check. Therefore, the operator can easily align the starter metal fitting 1 with the above-mentioned reference line (marked line), and can attach the starter metal fitting 1 accurately and horizontally to the base 50.
また、貫通孔１３が長穴として構成されており、上下方向の位置調整が容易であるため、スタータ金具１の基準線（墨出し線）に対する位置合わせを調整し易いものとなっている。 Further, since the through hole 13 is configured as an elongated hole and the position adjustment in the vertical direction is easy, it is easy to adjust the alignment of the starter metal fitting 1 with respect to the reference line (inking line).
さらに、水切り材８０の屋外側（図４および図５の左側）の面から突出したネジ９２の頭部９２ａは、スタータ金具１の縦片２の凹溝部２４内に収容されるため、スタータ金具１が傾いた状態で土台５０に取り付けられることを良好に防止することができる。ネジ９２の頭部９２ａは、「突出部」の一例である。 Further, the head 92a of the screw 92 protruding from the outdoor side (left side of FIGS. 4 and 5) of the drainer 80 is housed in the concave groove portion 24 of the vertical piece 2 of the starter metal fitting 1, so that the starter metal fitting It is possible to satisfactorily prevent the 1 from being attached to the base 50 in an inclined state. The head 92a of the screw 92 is an example of a “protruding portion”.
また、上側平板部２２ａおよび下側平板部２２ｂの両方が直接的あるいは水切り材８０を介して間接的に土台５０に当接する構成であるため、スタータ金具１の土台５０への取り付けがより安定する。 Further, since both the upper flat plate portion 22a and the lower flat plate portion 22b are configured to directly or indirectly abut the base 50 via the drainer 80, the starter metal fitting 1 is more stably attached to the base 50. ..
そして、こうして土台５０に取り付け固定されたスタータ金具１の横片４の基部４２に外壁部材７０を載置することにより、最下段の外壁部材７０の下端の施工が完了する。なお、外壁部材７０の下端面には、長手方向（水平方向）に沿う切欠き溝７０ａが形成されており、外壁部材７０を基部４２に載置する際に、スタータ金具１の横片４の折曲部４４が、切欠き溝７０ａに挿入されて嵌め合わされることにより施工される。 Then, by placing the outer wall member 70 on the base 42 of the horizontal piece 4 of the starter metal fitting 1 attached and fixed to the base 50 in this way, the construction of the lower end of the lowermost outer wall member 70 is completed. A notch groove 70a along the longitudinal direction (horizontal direction) is formed on the lower end surface of the outer wall member 70, and when the outer wall member 70 is placed on the base portion 42, the horizontal piece 4 of the starter metal fitting 1 is formed. The bent portion 44 is inserted into the notch groove 70a and fitted into the notch groove 70a to be fitted.
このように施工された外壁部材７０と土台５０との間には、図５に示すように、所定の隙間Ｌが確保されているため、外壁部材７０の屋内側（図５の右側）に侵入した雨水や、外壁部材７０の屋内側に生じた結露水などを、基部４２の通気穴４０を介して良好に排出することができると共に、通気性を確保することができる。 As shown in FIG. 5, a predetermined gap L is secured between the outer wall member 70 and the base 50 constructed in this way, so that the outer wall member 70 invades the indoor side (right side in FIG. 5). The rainwater and the dew condensation water generated on the indoor side of the outer wall member 70 can be satisfactorily discharged through the ventilation hole 40 of the base 42, and the ventilation can be ensured.
