Description

本発明は、壁パネルを躯体に取付ける際に該壁パネルと下地鋼材との間に予め設定された寸法を持った間隙を形成する目地受用金具および壁パネルの取付構造体に関する。 TECHNICAL FIELD The present invention relates to a joint receiving fitting and a wall panel mounting structure that forms a gap having a predetermined size between the wall panel and a base steel material when the wall panel is mounted to a building frame.

縦壁構法において、壁パネルと下地鋼材との間に所定間隔を形成する目地受用金具が配置され、目地受用金具は、壁パネルを固定的に支持することが一般的に実施されている(例えば特許文献1,2参照)。
この目地受け金具の固定的支持は、主に壁パネルの正圧(室外側から室内側へ作用する力)を建物の躯体へ伝達する役割がある。
In the vertical wall construction method, joint receiving metal fittings are arranged to form a predetermined interval between the wall panel and the base steel material, and the joint receiving metal fittings are generally implemented to support the wall panel in a fixed manner (for example, See Patent Documents 1 and 2).
The fixed support of this joint receiving metal fitting mainly plays the role of transmitting the positive pressure of the wall panel (the force acting from the outdoor side to the indoor side) to the frame of the building.

特許第3650176号公報Japanese Patent No. 3650176 特開平11-131660号公報JP-A-11-131660

しかしながら、上記文献に記載の技術では、壁パネルと下地鋼材間の所定寸法を、目地受け金具両端の折り曲げ寸法で固定的に確保している。そのため、下地鋼材の垂直片が室外側へ倒れた場合、下地鋼材垂直片の面に追従するように目地受け金具が固定されているので、壁パネル上下間の目地部に面外方向目違いが生じ、パネル壁面の建て入れ精度を出しづらい。 However, in the technique described in the above document, the predetermined dimension between the wall panel and the base steel material is fixedly secured by the bending dimension of both ends of the joint receiving metal fittings. Therefore, when the vertical piece of the base steel falls to the outside of the room, the joint bracket is fixed so that it follows the surface of the vertical piece of the base steel, so there is no misalignment in the out-of-plane direction in the joint between the top and bottom of the wall panel. It is difficult to achieve the erection accuracy of the panel wall surface.

現場によっては、目地受け金具をパネル建て込み後に差し挟む(後入れ)ケースがある。従来の目地受け金具は、折り曲げ加工で形成した所定寸法が固定的であるため、後入れ時に目地受け金具底端がパネル裏面に引っ掛かり、作業性を悪くしていた。 Depending on the site, there are cases where the joint receiving metal fittings are inserted after the panel is erected (post-insertion). Since the conventional joint receiving metal fitting is fixed in a predetermined size formed by bending, the bottom end of the joint receiving metal fitting is caught on the rear surface of the panel at the time of post-installation, resulting in poor workability.

パネルの巾方向両端に設置される目地受け金具は少なくとも2枚以上のパネルを支持する。従来の目地受け金具は、パネル支持面が固定的かつ一面で形成されているため、一方のパネルの影響を他方のパネルが受けてしまう。 The joint receiving metal fittings installed at both ends of the panel in the width direction support at least two or more panels. In conventional joint fittings, since the panel supporting surface is fixed and formed in one plane, one panel is affected by the other panel.

また、現場では、上下左右に4面のパネルが突き合せられた目地部分に目地受け金具が設置されることが多く、パネル巾方向の中央部に配置されたパネル取付け用金具による所定寸法の支持もあるため、4面のパネルを均一に当接させることが難しい。 In addition, on site, joint receiving metal fittings are often installed at the joints where four panels are butted vertically and horizontally. Therefore, it is difficult to evenly bring the four panels into contact with each other.

本発明は、このような従来の実情に鑑みて提案されたものであり、本発明の目的は、壁パネルと下地鋼材との間に所定の間隔を保つとともに、外壁パネルの位置決め機能を有し、さらにパネル当接部が壁パネルと弾性的に当接することで下地鋼材の精度に依存せず、均一にパネルを支持できる目地受け金具を提供することにある。 The present invention has been proposed in view of such conventional circumstances, and an object of the present invention is to maintain a predetermined gap between the wall panel and the base steel material, and to have a positioning function for the outer wall panel. Another object of the present invention is to provide a joint receiving fitting capable of uniformly supporting a panel without depending on the accuracy of the underlying steel material by elastically contacting the panel contacting portion with the wall panel.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing one configuration example of the joint receiving metal fitting of the present invention, and FIG. 2 is a plan view, a top view and a side view.
FIG. 3 is a diagram illustrating a mounting structure for mounting the wall panel to the base steel material. 4 is a perspective view showing a state in which the joint receiving metal fitting shown in FIG. 1 is attached to the base steel material and the wall panel, and FIG. 5 is a side view thereof.
In the following description, the upper side in FIGS. 1 to 5 will be referred to as "upper", and the lower side as "lower". Also, the right side is defined as "right" and the left side is defined as "left". The same applies to FIGS. 6 to 24 described later.

目地受用金具は、壁パネル11の両側であって少なくとも上下方向で隣接する2枚の壁パネル11(11A,11B)に対向して配置され、下地鋼材10の垂直片10aに係止されて該垂直片10aと壁パネル11との間隙を保持するものである。
目地受用金具1は、金属からなる板材が主に上下方向に折り曲げられてなり、下地鋼材(10)に当接する下地鋼材当接部(2)と、下地鋼材当接部(2)に対して、所定の高さで設けられた段差部(3,4)と、壁パネル(11)に当接するパネル当接部(5,6)と、を有し、壁パネル(11)からの正圧方向の力に対し、間隙の寸法を小さくすることができることを特徴とする。
The joint receiving metal fittings are arranged on both sides of the wall panel 11 so as to face at least two vertically adjacent wall panels 11 (11A, 11B), and are engaged with the vertical pieces 10a of the base steel material 10. It holds the gap between the vertical piece 10 a and the wall panel 11 .
The joint receiving metal fitting 1 is formed by bending a plate material made of metal mainly in the vertical direction. , stepped portions (3, 4) provided at a predetermined height, and panel abutting portions (5, 6) abutting against the wall panel (11), the positive pressure from the wall panel (11) It is characterized in that the dimension of the gap can be reduced with respect to the directional force.

このとき、下地鋼材係止部7は、図1に示すように、上パネル当接部5の段差部3とは反対側の端部から、下地鋼材当接部2側に戻るように折り曲げられて設けられていることが好ましい。上パネル当接部5の上端から下地鋼材係止部7が形成されることで、踏付け強度が大きくなり、下地鋼材10に目地受用金具1A(1)を取り付けた後、上から踏付けても金具が曲がることがない。 At this time, as shown in FIG. 1, the base steel locking portion 7 is bent from the end of the upper panel contact portion 5 opposite to the stepped portion 3 so as to return to the base steel contact portion 2 side. is preferably provided. Since the base steel locking part 7 is formed from the upper end of the upper panel contact part 5, the stepping strength is increased. The metal fittings do not bend.

また、下地鋼材係止部7は、後掲する図7(目地受用金具1B(1))に示すように、上パネル当接部5の略中央部から、下地鋼材当接部2側に戻るように折り曲げられて設けられていることが好ましい。プレス成型時に片側からのプレスで下地鋼材係止部7を成型することができ、成型工程を簡略化することができる。 Further, as shown in FIG. 7 (joint receiving metal fitting 1B(1)) described later, the base steel material locking portion 7 returns from the substantially central portion of the upper panel contact portion 5 toward the base steel material contact portion 2 side. It is preferably provided so as to be bent in such a manner. At the time of press molding, it is possible to form the base steel engaging portion 7 by pressing from one side, and the molding process can be simplified.

さらに、下地鋼材係止部7は、後掲する図10(目地受用金具1E(1))に示すように、下地鋼材当接部2から下地鋼材10を挟持するように折り曲げられて設けられていることが好ましい。パネル当接部5,6と下地鋼材係止部7が延設されていないので、パネルに作用する正圧に対して下地鋼材係止部7が動かない。 Furthermore, as shown in FIG. 10 (joint receiving fitting 1E(1)) described later, the base steel locking portion 7 is provided by being bent from the base steel contact portion 2 so as to sandwich the base steel 10. preferably. Since the panel abutting portions 5 and 6 and the base steel material engaging portion 7 are not extended, the base steel material engaging portion 7 does not move against the positive pressure acting on the panel.

そして、目地受用金具1A(1)は、下地鋼材当接部2と下地鋼材係止部7との間で、下地鋼材10を厚み方向に挟持することによって、目地受用金具1を前記下地鋼材10に係止するとともに、少なくとも下パネル当接部6が、壁パネル11に当接することによって、壁パネル11と下地鋼材10との間に間隙を形成する。
なお、通常、下パネル当接部6だけではなく上パネル当接部5も壁パネル11に当接している。そして、壁パネル11と下地鋼材10との間の間隙を決定するのは主に下パネル当接部6であり、上パネル当接部5は主にその間隙を保持する。
The joint receiving metal fitting 1A(1) holds the base steel material 10 between the base steel material abutment part 2 and the base steel material locking part 7 in the thickness direction, thereby allowing the joint receiving metal fitting 1 to be attached to the base steel material 10. , and at least the lower panel contact portion 6 contacts the wall panel 11 to form a gap between the wall panel 11 and the base steel material 10 .
Normally, not only the lower panel contact portion 6 but also the upper panel contact portion 5 is in contact with the wall panel 11 . The lower panel contact portion 6 mainly determines the gap between the wall panel 11 and the base steel material 10, and the upper panel contact portion 5 mainly maintains the gap.

本発明の目地受用金具1A(1)では、壁パネル11と下地鋼材10との間に所定の間隔を保つとともに、壁パネル11の位置決め機能を有し、さらにパネル当接部5,6が壁パネル11と弾性的に当接することで、壁パネル(11)からの正圧方向の力に対し、間隙の寸法を小さくすることができる。これにより下地鋼材10の取付け精度に依存せず、均一にパネルを支持することができる。 The joint receiving fitting 1A(1) of the present invention maintains a predetermined gap between the wall panel 11 and the base steel material 10, has a function of positioning the wall panel 11, and furthermore, the panel contact portions 5 and 6 are attached to the wall. By elastically contacting the panel 11, the size of the gap can be reduced against the positive pressure force from the wall panel (11). As a result, the panel can be uniformly supported without depending on the mounting accuracy of the base steel material 10 .

下地鋼材10に当接する下地鋼材当接部2は、下地鋼材10の垂直片10aの室外側の面と当接して該面の位置を拘束する機能を有する。 The base steel contact portion 2 that contacts the base steel 10 has the function of contacting the outdoor side surface of the vertical piece 10a of the base steel 10 to constrain the position of the surface.

下地鋼材当接部2の上下方向の両端に、段差部3,4が形成されている。
段差部3,4は、一方が下地鋼材当接部2に接続し、他方がパネル当接部5,6にそれぞれ接続し、下地鋼材当接部2とパネル当接部5,6との間に所定の高さで段差を形成している。
Stepped portions 3 and 4 are formed at both ends of the base steel contact portion 2 in the vertical direction.
One of the stepped portions 3 and 4 is connected to the base steel contact portion 2, and the other is connected to the panel contact portions 5 and 6, respectively. A step is formed at a predetermined height.

この段差部3,4は、下地鋼材当接部2とパネル当接部5,6の間隔、すなわち下地鋼材10と壁パネル11との間隔を、所定の設定寸法tに保持する機能を有する。
図2および図5に示すように、下地鋼材10と壁パネル11との間隔の寸法をt、段差部3,4の高さをt、板材の厚さをtとすると、
t=t+t
の関係を満たすように、段差部3,4の高さtが決定される。
The stepped portions 3 and 4 have the function of maintaining the distance between the base steel contact portion 2 and the panel contact portions 5 and 6, that is, the distance between the base steel material 10 and the wall panel 11, at a predetermined set dimension t.
As shown in FIGS. 2 and 5, when the distance between the base steel material 10 and the wall panel 11 is t, the height of the stepped portions 3 and 4 is t1, and the thickness of the plate material is t2 ,
t = t1 + t2
The height t1 of the stepped portions 3 and 4 is determined so as to satisfy the relationship of .

このとき、段差部3,4は、下地鋼材当接部2およびパネル当接部5,6に対して略垂直に設けられていてもよいが、斜めに設けられていることが好ましい。
段差部3,4が、下地鋼材当接部2に対して垂直ではなく、斜めに形成されることにより、上パネル当接部5および下パネル当接部6が、それぞれ、下地鋼材当接部2に対して弾性変形する(撓む)ことが可能となり、上パネル当接部5および下パネル当接部6が、それぞれ、下地鋼材当接部2に対して弾性を有し板バネ様の機能を有するものとなる。すなわち、壁パネル11からの正圧方向の力に対し、間隙の寸法を小さくすることができる。これにより、目地受用金具1A(1)は、壁パネル11を下地鋼材10に対して弾性的に支持することが可能となる。弾性的に支持することにより、パネルの面外方向への歪みを吸収して、壁パネル11を均一に支持できる(図6参照)。
At this time, the stepped portions 3 and 4 may be provided substantially vertically with respect to the base steel contact portion 2 and the panel contact portions 5 and 6, but are preferably provided obliquely.
Since the stepped portions 3 and 4 are formed not perpendicularly but obliquely to the base steel material contact portion 2, the upper panel contact portion 5 and the lower panel contact portion 6 are respectively aligned with the base steel material contact portion. 2, and the upper panel contact portion 5 and the lower panel contact portion 6 each have elasticity with respect to the base steel material contact portion 2 and have a leaf spring-like shape. function. That is, the dimension of the gap can be reduced against the positive pressure force from the wall panel 11 . As a result, the joint receiving fitting 1A(1) can elastically support the wall panel 11 with respect to the base steel material 10. As shown in FIG. By elastically supporting the wall panel 11, the distortion in the out-of-plane direction of the panel can be absorbed and the wall panel 11 can be uniformly supported (see FIG. 6).

壁パネル11の上部には、壁パネル11を下地鋼材10に取り付けるための取付金物(図示略)と、壁パネル11の両端にそれぞれ目地受用金具1A(1)が配される。また、壁パネル11の下部には、壁パネル11を下地鋼材10に取り付けるための取付金物(図示略)と、壁パネル11の両端に2つの目地受用金具1A(1)が配される。
このように、本実施の形態にかかる取付構造体では、下地鋼材10と壁パネル11との間に所定の間隙を形成する3点の取付金具について、弾性機能を有する目地受用金具1A(1)により、均一に壁パネル11を支持することができる。
Mounting metal fittings (not shown) for mounting the wall panel 11 to the base steel material 10 are provided on the upper portion of the wall panel 11, and joint receiving metal fittings 1A(1) are disposed at both ends of the wall panel 11, respectively. At the bottom of the wall panel 11, mounting metal fittings (not shown) for mounting the wall panel 11 to the base steel material 10 and two joint receiving metal fittings 1A(1) at both ends of the wall panel 11 are arranged.
As described above, in the mounting structure according to the present embodiment, the joint receiving metal fittings 1A(1) having an elastic function are attached to the three mounting metal fittings that form a predetermined gap between the base steel material 10 and the wall panel 11. Therefore, the wall panel 11 can be uniformly supported.

なお、段差部3,4は、両方とも、下地鋼材当接部2およびパネル当接部5,6に対して略垂直ではなく斜めに設けられていることが好ましいが、片方だけも壁パネル11を弾性支持することは可能であるため、本発明の効果を得ることはできる。 Both of the stepped portions 3 and 4 are preferably provided obliquely rather than substantially perpendicularly to the base steel contact portion 2 and the panel contact portions 5 and 6. can be elastically supported, the effects of the present invention can be obtained.

下地鋼材当接部2と、前記段差部3,4との成す角度が、10°以上89°以下であることが好ましく、45°以上85°以下であることがより好ましい。
これにより、目地受用金具1A(1)は、壁パネル11を下地鋼材10に対してより弾性的に支持することが可能となる。
The angle formed by the base steel material contact portion 2 and the stepped portions 3 and 4 is preferably 10° or more and 89° or less, more preferably 45° or more and 85° or less.
As a result, the joint receiving fitting 1A(1) can more elastically support the wall panel 11 with respect to the base steel material 10 .

特に、前記角度を45°以上とすることで、壁パネル11の正圧に対し、剛性を保持しつつ板厚を抑制でき、目地受用金具1A(1)の重量及びコストを削減できる。なお、角度が小さくなると、剛性を確保するために板厚を大きくしなければならなくなる。また、85°以下とすることで、正圧に対する支持力を保持し、かつ、目地受用金具1A(1)の成型時に、プレス機による金具の負担を軽減し、効率よく生産できる。 In particular, by setting the angle to 45° or more, it is possible to reduce the plate thickness while maintaining the rigidity against the positive pressure of the wall panel 11, thereby reducing the weight and cost of the joint receiving metal fitting 1A(1). It should be noted that if the angle becomes small, the plate thickness must be increased in order to ensure rigidity. Further, by setting the angle to 85° or less, the supporting force against positive pressure can be maintained, and the load on the joint receiving metal fitting 1A(1) can be reduced when the metal fitting is molded, resulting in efficient production.

なお、下地鋼材当接部2と段差部3,4との成す角度は、上パネル当接部5側(段差部3)と下パネル当接部6側(段差部4)とで同じであってもよいし、異なっていてもよいが、力を分散させて壁パネル11を均一に支持する観点からは、同じであることが好ましい。
角度が双方で異なる場合であっても、段差部3,4としての高さは均一である必要がある。すなわち、上パネル当接部5と下パネル当接部6とは、略同一平面上にある。
The angles formed by the base steel contact portion 2 and the stepped portions 3 and 4 are the same on the upper panel contact portion 5 side (stepped portion 3) and on the lower panel contact portion 6 side (stepped portion 4). They may be the same, or they may be different, but they are preferably the same from the viewpoint of distributing the force and supporting the wall panel 11 uniformly.
Even if the angles are different between the two, the heights of the stepped portions 3 and 4 must be uniform. That is, the upper panel contact portion 5 and the lower panel contact portion 6 are substantially on the same plane.

上パネル当接部5は、一方の段差部3から上側に延設される。下パネル当接部6は、他方の段差部4から下側に向けて延設される。これら上パネル当接部5および下パネル当接部6は、下地鋼材当接部2に対し所定の間隙を有するように設けられる。また、上パネル当接部5および下パネル当接部6との間に所定のギャップGをもって配されていると好ましい(図5参照)。ギャップGがあることで、壁パネル11の短辺小口縁11bを避けて壁パネル11と当接しやすくできる。
上パネル当接部5および下パネル当接部6は、それぞれ壁パネル11の室内側の面に当接することにより、壁パネル11の表面を支持拘束する。
The upper panel contact portion 5 extends upward from one of the stepped portions 3 . The lower panel contact portion 6 extends downward from the other stepped portion 4 . The upper panel contact portion 5 and the lower panel contact portion 6 are provided so as to have a predetermined gap with respect to the base steel material contact portion 2 . Moreover, it is preferable that a predetermined gap G is provided between the upper panel contact portion 5 and the lower panel contact portion 6 (see FIG. 5). The presence of the gap G makes it possible to easily contact the wall panel 11 while avoiding the edge 11b of the short side of the wall panel 11.例文帳に追加
The upper panel contacting portion 5 and the lower panel contacting portion 6 support and constrain the surface of the wall panel 11 by contacting the interior side surface of the wall panel 11 .

下地鋼材係止部7は、上パネル当接部5から延びる片を下地鋼材当接部2側に戻るように、下地鋼材当接部2に向けて、下方に折り曲げて形成されている。このとき、下地鋼材係止部7と上パネル当接部5の裏面(下地鋼材側の面)とのなす角を鋭角或いは直角とし、下地鋼材係止部7を下方に折り曲げる角度を直角または鈍角とすることで、下地鋼材係止部7の垂直片10aと嵌合する部分をフック状に形成することが好ましい。 The base steel locking portion 7 is formed by bending a piece extending from the upper panel contact portion 5 downward toward the base steel contact portion 2 so as to return to the base steel contact portion 2 side. At this time, the angle formed by the base steel material engaging portion 7 and the rear surface of the upper panel abutment portion 5 (surface on the side of the base steel material) is set to an acute angle or a right angle, and the angle at which the base steel material engaging portion 7 is bent downward is a right angle or an obtuse angle. By doing so, it is preferable to form the portion of the base steel material engaging portion 7 that engages with the vertical piece 10a into a hook shape.

また、下地鋼材当接部2と下地鋼材係止部7との間に、下地鋼材10の垂直片10aの厚さとほぼ同じ間隙を形成するように形成されている。
下地鋼材係止部7は、下地鋼材10の室内側の面と当接して、目地受用金具1A(1)を下地鋼材10に係止する機能を有する。
Further, between the base steel material abutting portion 2 and the base steel material locking portion 7, a gap is formed so as to be substantially the same as the thickness of the vertical piece 10a of the base steel material 10. As shown in FIG.
The base steel locking portion 7 has a function of contacting the interior side surface of the base steel 10 to lock the joint receiving metal fitting 1A(1) to the base steel 10 .

このような目地受用金具1A(1)は、金属製の板材を主に上下方向に折り曲げることにより形成される。
板材の厚みは、0.6mm以上2.3mm以下であることが好ましく、1.2mm以上1.6mm以下であることがより好ましい。目地受用金具1A(1)を構成する板材の厚みを上記範囲とすることで、壁パネル11を支持するのに十分な剛性を維持しつつ、適度な弾性も有するものとなり、壁パネル11を下地鋼材10に対してより弾性的に支持することが可能となる。
板材が厚すぎると、高い剛性を有する一方で、変形した際の復元力が十分ではなく弾性が不足し、壁パネル11を下地鋼材10に対して弾性的に支持することが困難になる。また板材を折り曲げ加工して目地受用金具1A(1)を作製する際の工程が困難になる。板材が薄すぎると、弾性は十分である一方で剛性が不足してしまう。
Such a joint receiving metal fitting 1A(1) is formed by bending a metal plate mainly in the vertical direction.
The thickness of the plate material is preferably 0.6 mm or more and 2.3 mm or less, more preferably 1.2 mm or more and 1.6 mm or less. By setting the thickness of the plate material constituting the joint receiving metal fitting 1A(1) within the above range, it is possible to maintain sufficient rigidity to support the wall panel 11 and also to have appropriate elasticity. It becomes possible to support the steel material 10 more elastically.
If the plate material is too thick, although it has high rigidity, it does not have sufficient restoring force when deformed and lacks elasticity. Moreover, the process of manufacturing the joint receiving metal fitting 1A(1) by bending the plate material becomes difficult. If the plate material is too thin, it has sufficient elasticity but lacks rigidity.

特に、板材の厚みを1.2mm以上とすることで、壁パネル11からの正圧方向の力(押圧)に対し、目地受け金具が一定の剛性を確保しやすく、所望の荷重負担を容易にし、パネル取付金具へ作用する荷重を軽減することができる。また、板材の厚みが大きいと、弾性を得るためには角度を緩くする必要がある。つまり見附面積の増大に繋がる。そこで1.6mm以下とすることで、剛性弾性を確保しつつ、金具の見附面積低減を容易にし、金具の重量低減ならびにコスト低減することができる。 In particular, by setting the thickness of the plate material to 1.2 mm or more, it is easy for the joint receiving metal fitting to secure a certain rigidity against the force (pressing force) in the positive pressure direction from the wall panel 11, and the desired load can be easily carried. , the load acting on the panel mounting bracket can be reduced. Also, if the thickness of the plate material is large, it is necessary to make the angle loose in order to obtain elasticity. In other words, it leads to an increase in the estimated area. Therefore, by setting the thickness to 1.6 mm or less, it is possible to easily reduce the mounting area of the metal fitting while ensuring rigidity and elasticity, and to reduce the weight and cost of the metal fitting.

図3は、下地鋼材に壁パネルを取り付ける取付構造を説明する図である。図4は、上述したような目地受用金具1A(1)を用いた、壁パネルの取付構造体を室外側から見た斜視図であり、図5はその側面図である。
すなわち、本実施形態の取付構造体は、建物躯体側の下地鋼材10に壁パネル11が取付けられてなる壁パネルの取付構造体であって、下地鋼材10に係止されるとともに、下地鋼材10と壁パネル11との間に予め設定された間隙を形成する目地受用金具1A(1)を備える。
FIG. 3 is a diagram illustrating a mounting structure for mounting the wall panel to the base steel material. FIG. 4 is a perspective view of a wall panel mounting structure using the above-described joint receiving fitting 1A(1), and FIG. 5 is a side view thereof.
That is, the mounting structure of the present embodiment is a wall panel mounting structure in which a wall panel 11 is attached to a base steel material 10 on the building skeleton side. and a wall panel 11 to form a preset gap.

図3~図5に示すように、建物の躯体を構成する梁13の上フランジ13aにアングル材からなる下地鋼材10が配置され、下地鋼材10の垂直片10aの位置を上フランジ13aの室外側の端部からの張り出し長さを予め設定された値に調整した後、水平片10bを上フランジ13aに溶接することで固定されている。 As shown in FIGS. 3 to 5, a base steel material 10 made of an angle material is placed on the upper flange 13a of the beam 13 that constitutes the frame of the building, and the position of the vertical piece 10a of the base steel material 10 is positioned on the outdoor side of the upper flange 13a. is fixed by welding the horizontal piece 10b to the upper flange 13a after adjusting the projection length from the end of the horizontal piece 10b to a preset value.

下地鋼材10の室外側には複数の壁パネル11が連設されており、夫々の壁パネル11は、下端が自重受け金物14に載置されて支持され、且つ下地鋼材10との間に目地受用金具1A(1)を介在させることで、壁パネル11と下地鋼材10との間隙を予め設定された寸法(設定寸法t)に保持し、この状態で壁パネル11の上部は、ボルトで取り付けられたイナズマ型のプレートを介して下地鋼材10の垂直片10aに取付けられている。 A plurality of wall panels 11 are connected to the outdoor side of the base steel material 10, and the lower end of each wall panel 11 is placed on and supported by a weight receiving metal fitting 14, and a joint is provided between the base steel material 10. By interposing the receiving fitting 1A(1), the gap between the wall panel 11 and the base steel material 10 is maintained at a preset dimension (set dimension t), and in this state, the upper part of the wall panel 11 is attached with bolts. It is attached to the vertical piece 10a of the base steel material 10 via the bolt-shaped plate.

目地受用金具1A(1)は、図5に示すように、下地鋼材10の垂直片10aの上方から差し込み、下地鋼材係止部7を垂直片10aに嵌合させることで係止され、且つ下地鋼材係止部7及び下地鋼材当接部2が垂直片10aに当接する。 As shown in FIG. 5, the joint receiving fitting 1A(1) is inserted from above the vertical piece 10a of the base steel material 10, and is locked by fitting the base steel material locking portion 7 to the vertical piece 10a. The steel locking portion 7 and the underlying steel contact portion 2 contact the vertical piece 10a.

すなわち、下地鋼材当接部2は、下地鋼材10の垂直片10aの室外側の面と当接し、下地鋼材係止部7は、垂直片10aの室内側の面と当接して、これら下地鋼材係止部7と下地鋼材当接部2とによって、垂直片10aを挟み込むように取付けられる。 That is, the base steel material abutting portion 2 abuts on the outdoor surface of the vertical piece 10a of the base steel material 10, and the base steel material locking portion 7 abuts on the indoor surface of the vertical piece 10a. The vertical piece 10a is attached between the engaging portion 7 and the base steel contact portion 2 so as to sandwich the vertical piece 10a.

このとき、下地鋼材当接部2と下地鋼材係止部7との間の間隙の寸法が、下地鋼材10の垂直片10aの厚さとほぼ同じとされているので、垂直片10aを下地鋼材当接部2と下地鋼材係止部7とでしっかりと挟み込んで、取付け後もずれたりすることなく、目地受用金具1A(1)を下地鋼材10に係止することができる。 At this time, since the dimension of the gap between the base steel material abutting portion 2 and the base steel material locking portion 7 is set to be substantially the same as the thickness of the vertical piece 10a of the base steel material 10, the vertical piece 10a contacts the base steel material. The joint receiving fitting 1A (1) can be locked to the base steel material 10 without slipping even after installation by being firmly sandwiched between the contact part 2 and the base steel material locking part 7.例文帳に追加

そして目地受用金具1A(1)が下地鋼材10に取付けられたとき、下地鋼材10の垂直片10aと目地受用金具1A(1)のパネル当接部5,6との距離は、段差部3,4の高さである設定寸法tと等しくなり、壁パネル11の室内側の面をパネル当接部5,6に当接させて取付けることで、壁パネル11と下地鋼材10との間隙を予め設定された寸法tに保持することが可能である。 When the joint receiving metal fitting 1A(1) is attached to the base steel material 10, the distance between the vertical piece 10a of the base steel material 10 and the panel contact portions 5, 6 of the joint receiving metal fitting 1A(1) is 4, and by attaching the wall panel 11 with its indoor side surface in contact with the panel contact portions 5 and 6, the gap between the wall panel 11 and the base steel material 10 can be adjusted in advance. It is possible to hold the set dimension t.

また、目地受用金具1A(1)は、下地鋼材10に取付けるに際し、上パネル当接部5から延びて形成された下地鋼材係止部7によって垂直片10aを嵌合して取付けるので、下地鋼材10の垂直片10aの室内側に大きな隙間を確保する必要がなく、梁に柱が配置されているような場合であっても、下地鋼材10に特別な加工を施すことなく容易に取付けることができる。 Further, when the joint receiving metal fitting 1A(1) is attached to the base steel material 10, the vertical piece 10a is fitted by the base steel material engaging portion 7 formed by extending from the upper panel abutment portion 5. It is not necessary to secure a large gap on the indoor side of the vertical piece 10a of 10, and even if a column is arranged on a beam, it can be easily attached without applying special processing to the base steel material 10. can.

目地受用金具1A(1)は、上パネル当接部5と下パネル当接部6が、間に所定のギャップGをもって配されており、上下に配された一対の壁パネル11の目地12の部分に配され、上パネル当接部5が、上側の壁パネル11(上パネル11A)に当接し、下パネル当接部6が、下側の壁パネル11(下パネル11B)に当接するように取付けられる。
上パネル当接部5で上パネル11Aを支持し、下パネル当接部6が下パネル11Bを支持することで、上パネル11Aと下パネル11Bの突合せ部分における面外方向の目違いを吸収することができ、壁パネル11を均一に支持することができる。
The joint receiving fitting 1A(1) has an upper panel contact portion 5 and a lower panel contact portion 6 arranged with a predetermined gap G therebetween, and the joint 12 between a pair of wall panels 11 arranged vertically. so that the upper panel contact portion 5 contacts the upper wall panel 11 (upper panel 11A) and the lower panel contact portion 6 contacts the lower wall panel 11 (lower panel 11B). Mounted on.
The upper panel contact portion 5 supports the upper panel 11A, and the lower panel contact portion 6 supports the lower panel 11B, thereby absorbing misalignment in the out-of-plane direction at the butted portion between the upper panel 11A and the lower panel 11B. and the wall panel 11 can be uniformly supported.

このとき、目地受用金具1A(1)の巾中央に貫通穴8が設けられているので、目地受用金具1A(1)を下地鋼材10および壁パネル11に取付ける際に、この貫通穴8を観察穴として、下地鋼材10の垂直片10aの水平墨や割付墨、また上パネル11Aと下パネル11Bとの突合せ部分である目地12を確認し位置合わせしながら、目地受用金具1A(1)を壁パネル11に対して位置決めすることができる。
これにより、より正確な取付けを行うことができるとともに、作業をより行いやすくすることができる。貫通穴8は、スリットでもよい。また貫通穴、および/またはスリットは複数あってもよい。
At this time, since a through hole 8 is provided in the center of the width of the joint receiving metal fitting 1A(1), the through hole 8 is observed when the joint receiving metal fitting 1A(1) is attached to the base steel material 10 and the wall panel 11. As a hole, the joint receiving metal fitting 1A (1) is attached to the wall while confirming and aligning the horizontal and split marks of the vertical piece 10a of the base steel material 10, and the joint 12, which is the butted portion between the upper panel 11A and the lower panel 11B. It can be positioned relative to panel 11 .
As a result, more accurate mounting can be performed, and the work can be made easier. The through hole 8 may be a slit. Also, there may be a plurality of through holes and/or slits.

目地受用金具1A(1)に上パネル当接部5と下パネル当接部6の間に配された所定のギャップGが、目地12の部分と対向して取り付けられる。なお、目地受用金具1A(1)が壁パネル11の短辺小口縁11bに当接しないように、短辺小口縁11bから少し離した位置、例えば3mm程度以上離した位置に当接されると好ましい。目地12の短辺小口縁11bに当接しないように目地受用金具1A(1)を配することで、地震などで躯体が変形した場合でもパネルに微細な割れや欠けが発生しにくくなる。
また、下パネル当接部6は壁パネル11の短辺小口縁11bから離して配されることが好ましい。パネル製造誤差により下パネル11Bのパネル長さが若干短かい場合でも、下パネル当接部6と下パネル11Bとの当接面積を確保して正圧に対する支持力を保持しやすくなる。
なお、上下のパネル当接部5,6を、ともに短辺小口縁11bから離して配されることが好ましいのは言うまでもない。
A predetermined gap G between the upper panel contact portion 5 and the lower panel contact portion 6 is attached to the joint receiving metal fitting 1A(1) so as to face the joint 12 portion. In order to prevent the joint receiving metal fitting 1A(1) from coming into contact with the short edge 11b of the wall panel 11, it should be placed at a position slightly separated from the short edge 11b, for example, at a position separated by about 3 mm or more. preferable. By arranging the joint receiving fitting 1A(1) so as not to abut against the edge 11b of the short side of the joint 12, even when the frame is deformed due to an earthquake or the like, the panel is less likely to be finely cracked or chipped.
Moreover, it is preferable that the lower panel contact portion 6 is arranged away from the short side edge 11 b of the wall panel 11 . Even if the panel length of the lower panel 11B is slightly short due to panel manufacturing error, the contact area between the lower panel contact portion 6 and the lower panel 11B is ensured, and the supporting force against the positive pressure can be easily maintained.
Needless to say, both the upper and lower panel contact portions 5 and 6 are preferably arranged away from the short side edge 11b.

ここで、壁パネル11の短辺の角部の形状は特に限定されるものではなく、尖ったピン角の場合や、施工上の都合により3mm~10mm程度の面取り部分11aが設けられる場合があるが、その面取りの有無や形状および寸法は問わない。 Here, the shape of the corners of the short sides of the wall panel 11 is not particularly limited, and there are cases in which a sharp pin angle is provided, or a chamfered portion 11a of about 3 mm to 10 mm is provided for construction reasons. However, the presence or absence of chamfering, shape and dimensions are not limited.

本実施形態の目地受用金具1A(1)は、上パネル11Aと下パネル11Bとの目地だけではなく、上下左右に4枚の壁パネルが突き合わされた目地部分に配されてもよい。 The joint receiving fitting 1A(1) of the present embodiment may be arranged not only at the joint between the upper panel 11A and the lower panel 11B, but also at the joint where four wall panels are butted vertically and horizontally.

本発明の目地受用金具1A(1)によって支持される壁パネル11は、ALC(Autoclaved Lightweight aerated Concrete)パネルであることが好ましい。
ALCパネルは母材強度が比較的に低く、扱いによっては外周部で割れ欠けが発生しやすい材料ではあるが、本実施形態の目地受用金具1A(1)で弾性的に支持することで躯体や下地鋼材10の施工精度の影響や地震などで躯体が変形した場合でもパネルに微細な割れや欠けが発生しにくくできる。
The wall panel 11 supported by the joint fitting 1A(1) of the present invention is preferably an ALC (Autoclaved Lightweight Aerated Concrete) panel.
The ALC panel has a relatively low base material strength, and is a material that is prone to cracking and chipping at the outer periphery depending on how it is handled. Even if the building structure is deformed due to the effect of construction accuracy of the base steel material 10 or an earthquake, the panel is less likely to be finely cracked or chipped.

以上説明したように本発明に係る壁パネルの取付構造体では、下地鋼材係止部7を下地鋼材10の垂直片10aに係止することで目地受用金具1A(1)を下地鋼材10に取付けると共に、パネル当接部5,6をそれぞれ壁パネル11に当接させることで、パネル当接部5,6と下地鋼材10との間隔を予め設定された間隙と等しい寸法に保持することができる。このため、壁パネル11をパネル当接部5,6に接触させて取付けたとき、該パネルと下地鋼材10の間隙を予め設定された値に保持することができ、壁パネル11が位置決めされる。 As described above, in the wall panel mounting structure according to the present invention, the joint receiving fitting 1A (1) is attached to the steel substrate 10 by engaging the steel substrate engaging portion 7 with the vertical piece 10a of the steel substrate 10. At the same time, by bringing the panel contact portions 5 and 6 into contact with the wall panel 11, the gap between the panel contact portions 5 and 6 and the base steel material 10 can be maintained at a dimension equal to the preset gap. . Therefore, when the wall panel 11 is attached in contact with the panel abutting portions 5 and 6, the gap between the panel and the base steel material 10 can be held at a preset value, and the wall panel 11 is positioned. .

そして特に、本発明に係る壁パネル11の取付構造体では、段差部3,4が、下地鋼材当接部2に対して垂直ではなく、斜めに形成されることにより、図6に示すように、パネル面外方向への外力が加わった際に、パネル当接部5,6が下地鋼材当接部2に対して弾性変形し、上パネル当接部5および下パネル当接部6が、それぞれ、下地鋼材当接部2に対して弾性を有し板バネ様の機能を有するものとなる。これにより壁パネル11を下地鋼材10に対して弾性的に支持することが可能となる。壁パネル11を弾性的に支持することにより、壁パネル11からの正圧方向の力に対し、間隙の寸法を小さくすることができ、パネルの面外方向への歪みを吸収して、壁パネル11を均一に支持できる。また、下地鋼材10の施工精度に依存しないため、パネルの面外方向の目違いを吸収できる。 In particular, in the mounting structure of the wall panel 11 according to the present invention, the stepped portions 3 and 4 are not perpendicular to the base steel contact portion 2, but are formed obliquely, as shown in FIG. , the panel contact portions 5 and 6 are elastically deformed with respect to the base steel material contact portion 2, and the upper panel contact portion 5 and the lower panel contact portion 6 are Each of them has elasticity with respect to the base steel material contact portion 2 and has a leaf spring-like function. This allows the wall panel 11 to be elastically supported on the base steel material 10 . By elastically supporting the wall panel 11, it is possible to reduce the dimension of the gap against the positive pressure force from the wall panel 11, absorb the distortion in the out-of-plane direction of the panel, and 11 can be uniformly supported. Moreover, since it does not depend on the construction accuracy of the base steel material 10, misalignment in the out-of-plane direction of the panel can be absorbed.
