Description

【０００１】
【発明の属する技術分野】
この発明は、建築材の取付け構造及び取付け金具に関し、特に、カーテンウォール構造建築物において、その外壁材を梁等の構造躯体へ取り付けるための取付け構造及び取付け金具に係る。
【０００２】
【従来の技術】
一般に、カーテンウォール構造の建築物では、地震や強風による水平力を構造躯体の揺れによって吸収し、水平力を支持しない外壁材については、構造躯体の揺れに伴って回転するいわゆるロッキング機能を持たせるようにしている。
【０００３】
図８は、上記のようなカーテンウォール構造建築物における外壁材の取付け構造を示している。図において、(50)は、構造躯体を構成する梁であって、この梁(50)の上部フランジ(51)に、板状の支持プレート(52)がボルト(53)によって固定されている。
【０００４】
(54)は、梁(50)の外側に取り付けられる外壁材であり、この外壁材(54)の裏面側における上下端部には、ファスナー(55)(56)がそれぞれ固定されている。そして、下側の外壁材(54)における上側ファスナー(55)のボルト孔(60)に、垂直ボルト(61)が下側から挿入され、更にその先端が、梁(50)側の支持プレート(52)のボルト孔(62)へ挿入されるとともに、雄ネジ部に螺合したナット(63)で、下方に落下しないように支持している。更に、支持プレート(52)よりも上方に突出する垂直ボルト(61)先端のピン部(65)が、上方に設置された別の外壁材(54)の下側ファスナー(56)のピン挿入孔(64)に挿入されている。
【０００５】
このような取付け状態において、上側ファスナー(55)を支持している垂直ボルト(61)は、支持プレート(52)のボルト孔(62)内を摺動して上下に移動自在であり、また下側ファスナー(56)が垂直ボルト(61)のピン部(65)に沿って上下に移動自在であることから、梁(50)の揺れに追従して外壁材(54)(54)がそれぞれ斜めに傾くようにして回転するようになっている。
【０００６】
【発明が解決しようとする課題】
しかしながら、従来の上記構造においては、外壁材(54)の取付けに際して、外壁材(54)を所定位置に保持した状態で、支持プレート(52)や上側ファスナー(55)のボルト孔(60)(62)へ垂直ボルト(61)を挿入したり、垂直ボルト(61)にナット(63)を螺合するといった面倒な作業が必要であった。
【０００７】
また、このような作業は、建物外部側からは外壁材(54)が邪魔になって困難を要するので、主として建物内部側から行うようにしている。このため、建物の新築時においては、内壁材等の内装部材を施工する前に、外壁材(54)を取り付けるようにすれば特に問題はないが、建物完成後において、経時劣化や損傷、リフォーム等により、外壁材(54)を交換するような場合には、既に内装部材が施工されている状態にあるので、新しい外壁材(54)の取付け作業に際しては、内装部材を取り壊すといった大掛かりな工事が必要となっていた。
【０００８】
この発明は、上記の不具合を解消して、外壁材等の建築材を構造躯体等の被取付け体に簡単かつ確実に取り付けることができ、建物完成後における外壁材の交換作業も簡単に済ますことができる建築材の取付け構造及び取付け金具の提供を目的とする。
【０００９】
【課題を解決するための手段】
上記の課題を解決するため、この発明の建築材の取付け構造は、被取付け体側の棒状部材に、建築材側の係止部材を係合させて、建築材を被取付け体に取り付けるようにしたものであり、前記係止部材に、一端部が開放し、且つ、一部が拡張した棒状部材貫通用のスリットを形成するとともに、前記建築材を移動させながら前記係止部材のスリットの一端部から前記棒状部材を差し入れるときに、そのスリットの拡張部に嵌合してスリット一端部からの棒状部材の抜けを防止する抜け止め部材を、前記棒状部材に設けたことを特徴とする。
【００１０】
そして、前記抜け止め部材の挿通孔に前記棒状部材を挿通させるようにして、前記抜け止め部材を、前記棒状部材に沿って移動自在に取り付けてある。
【００１１】
また、前記棒状部材に、前記抜け止め部材を前記拡張部に嵌合する方向へ付勢する付勢体を設けている。
【００１２】
さらに、前記抜け止め部材を前記係止部材との干渉を避ける待避位置に保持するストッパを設けて、前記建築材を移動させながら前記係止部材のスリットの一端部から前記棒状部材を差し入れるときに、前記ストッパが前記係止部材に押されて外れることで、前記の抜け止め部材の保持を解除するようにしている。
【００１３】
具体的には、前記被取付け体が梁等の構造躯体であり、前記建築材が外壁材とされていて、前記外壁材の裏面から突出した前記係止部材に、建物内外方向に沿って前記スリットを形成し、その建物内方向側の一端部が開放し、建物外方向側の他端部が拡張されている。
【００１４】
この発明の建築材の取付け金具は、被取付け体に取り付けられて、前記建築材側の係止部材のスリットを貫通する棒状部材と、その棒状部材に設けられて、前記建築材を移動させながら前記係止部材のスリットの開放端部から前記棒状部材を差し入れるときに、そのスリットの拡張部に嵌合してスリットの開放端部からの棒状部材の抜けを防止する抜け止め部材とを備えたことを特徴とする。
【００１５】
また、前記抜け止め部材を前記拡張部に嵌合する方向へ付勢する付勢体を設けている。さらに、前記抜け止め部材を前記係止部材との干渉を避ける待避位置に保持するストッパを設けて、前記建築材を移動させながら前記係止部材のスリットの開放端部から前記棒状部材を差し入れるときに、前記ストッパが前記係止部材に押されて外れることで、前記の抜け止め部材の保持を解除するようにしている。
【００１６】
【発明の実施の形態】
以下、この発明を図面に基づいて詳細に説明する。図１において、(１)は、この発明の被取付け体としてのＨ型鋼製の梁である。(２)は、板状の支持プレートであって、支持プレート(２)の一端部が、前記梁(１)の上部フランジ(３)上面に設置されて、ボルト(４)及びナット(５)によって固定されている。梁(１)よりも建物外方向側に突出する支持プレート(２)の他端部には、ボルト孔(６)が形成してある。
【００１７】
(７)(７)は、前記梁(１)よりも建物外方向側に取り付けられるこの発明の建築材としての外壁材であって、軽量コンクリート板その他のコンクリート板からなるものである。これらの外壁材(７)(７)の裏面には、図２に示すように、その上端部において、一対の略Ｌ字型の上側ファスナー(８)(８)が取り付けられ、下端部において、一対の略Ｌ字型の下側ファスナー(９)(９)が取り付けられている。
【００１８】
上側ファスナー(８)は、図１及び図３に示すように、外壁材(７)裏面に図示しないインサートナット及びボルト(17)によって固定された垂直片(13)と、その垂直片(13)の上端部から建物内方向側へ突出する水平片(14)と、この水平片(14)の上面に張り合わされた補強片(15)とからなる。そして、水平片(14)と補強片(15)によって、この発明の係止部材(20)が構成されており、この係止部材(20)には、スリット(21)が建物内外方向に沿って形成されている。このスリット(21)の建物内方向側の一端部は開放しており、建物外方向側の他端部には、略円形に拡張された拡張部(22)が形成されている。
【００１９】
下側ファスナー(９)は、図１に示すように、外壁材(７)裏面に埋め込まれた横材(10)にボルト(11)及びナット(12)によって固定された垂直片(25)と、その垂直片(25)の下端部から建物内方向側へ突出する水平片(26)とからなる。そして、水平片(26)には、ピン挿通孔(27)が形成されている。
【００２０】
(30)は、外壁材(７)(７)側のファスナー(８)(９)…を係合させて、外壁材(７)(７)を梁(１)に取り付けるための取付け金具であって、この取付け金具(30)は、図４に示すように、棒状部材としての垂直ボルト(31)を備えている。垂直ボルト(31)は、その先端に雄ネジを有しない棒状のピン部(32)が形成してあり、そのピン部(32)が上向きで頭部(33)が下向きになるようにして、支持プレート(２)のボルト孔(６)へ挿入されるとともに、雄ネジ部に螺合したナット(34)で、下方に落下しないように支持プレート(２)に吊り下げ支持されている。
【００２１】
また、取付け金具(30)は、係止部材(20)におけるスリット(21)の拡張部(22)に対応して略円筒状に形成された抜け止め部材(35)と、この抜け止め部材(35)を下方へ付勢する付勢体としてのコイルバネ(37)とを備えている。
【００２２】
抜け止め部材(35)は、その中央の挿通孔(38)に垂直ボルト(31)が挿通された状態で、垂直ボルト(31)に沿って上下動自在に取り付けられている。この抜け止め部材(35)の上端部には、外方に張り出した鍔(39)が形成されている。
【００２３】
コイルバネ(37)も同様に、垂直ボルト(31)が挿通された状態で、垂直ボルト(31)に沿って上下動自在に取り付けられている。そして、このコイルバネ(37)は、垂直ボルト(31)を支持プレート(２)に吊り下げ支持した状態において、支持プレート(２)と抜け止め部材(35)との間に介装されている。なお、(40)は、垂直ボルト(31)の頭部(33)に載せられた座金である。
【００２４】
上記構成において、梁(１)への外壁材(７)(７)の取付けに際しては、まず梁(１)側の支持プレート(２)に、取付け金具(30)の垂直ボルト(31)を取り付けて、図５に示すように、頭部(33)上の座金(40)と抜け止め部材(35)の鍔(39)との間に、コイルバネ(37)の付勢力に抗して抜け止め部材(35)を押し上げるストッパ(41)を取り付ける。このストッパ(41)は、例えば角筒を略半割にした形状とされていて、その側面開口部(42)が建物外方向側を向くようにして配置される。
【００２５】
この状態において、下側の外壁材(７)を建物外部側から建物内方向へ水平移動させて、その係止部材(20)のスリット(21)の一端部すなわち開放端部から垂直ボルト(31)をスリット(21)内へ差し入れる。このとき、抜け止め部材(35)はストッパ(41)によって係止部材(20)とは干渉しない待避位置すなわち上方位置に保持されており、係止部材(20)は、座金(40)と抜け止め部材(35)との間に押し込まれるようになっている。
【００２６】
このようにして係止部材(20)が押し込まれると、図６に示すように、ストッパ(41)が係止部材(20)に押されて外れ、抜け止め部材(35)が係止部材(20)上に落下する。そして、係止部材(20)を、そのスリット(21)の拡張部(22)と抜け止め部材(35)とが一致する位置までさらに押し込むと、抜け止め部材(35)が拡張部(22)内に落下して嵌合し、これによってスリット(21)を貫通した垂直ボルト(31)の開放端部からの抜けが防止される。しかも、垂直ボルト(31)の頭部(33)は、係止部材(20)の下面に当接しており、スリット(21)からの垂直ボルト(31)の上方への抜けも防止される。これによって、係止部材(20)が垂直ボルト(31)に係合した状態となる。このとき、抜け止め部材(35)は、コイルバネ(37)によって下方すなわち拡張部(22)に嵌合する方向に付勢されているので、抜け止め部材(35)が拡張部(22)から外れ難く、係合状態を確実に維持することができる。
【００２７】
そして、このようにして下側の外壁材(７)を取り付けた後に、図１に示すように、上側の外壁材(７)を同様にして取り付けるが、このとき上側の外壁材(７)における下側ファスナー(９)のピン挿通孔(27)へ、支持プレート(２)よりも上方に突出する垂直ボルト(31)のピン部(32)が挿入される。
【００２８】
このような取付け状態において、下側外壁材(７)を吊り下げる垂直ボルト(31)は、支持プレート(２)のボルト孔(６)内を摺動して上下に移動可能であり、また上側外壁材(７)が垂直ボルト(31)のピン部(32)に沿って上下に移動自在であることから、梁(１)の揺れに追従して外壁材(７)(７)がそれぞれ斜めに傾くようにして回転して、ロッキング動作を許容している。
【００２９】
なお、この発明は、上記実施形態に限定されるものではなく、この発明の範囲内で上記実施形態に多くの修正及び変更を加え得ることは勿論である。
【００３０】
例えば、この発明は、外壁材の取り付けだけに限らず、例えば内壁材やその他外壁材以外の建築材の取り付けに適用しても良い。また、付勢体については、コイルバネに限らず、例えば板バネやゴム等を用いても良く、またストッパについても、上記実施形態のような角筒を半割状にしたものに限定されず、抜け止め部材を待避位置で保持でき、係止部材に押されて外れる構造のものであれば、どのような形状のものであっても良い。さらに、例えば抜け止め部材を自重等によってスリットの拡張部に嵌合させるようにすれば、付勢体を廃止しても良く、また、図７に示すように、例えば係止部材の押し込みによって抜け止め部材が自動的に押し上がって待避位置に移動するようなカム面構造とすれば、ストッパを廃止しても良い。
【００３１】
【発明の効果】
以上のように、この発明によれば、建築材を移動させて、その係止部材のスリットへ被取付け体側の棒状部材を差し入れるだけで、抜け止め部材がスリットの拡張部に自動的に嵌合して棒状部材の抜けが防止され、係止部材と棒状部材が互いに係合するようになっているので、建築材を被取付け体に対してワンタッチで簡単に取り付けることができる。従って、閉塞された部位に対して建築材を一方向からのアプローチして取り付ける構造として有効である。
【００３２】
特に、この取付け構造を、外壁材の梁等への取付けに適用し、例えば係止部材のスリットを建物内外方向に沿って形成して、その建物内方向側の端部を開放することで、外壁材を建物外部側から建物内方向へ向けて移動させるだけで、係止部材と棒状部材が互いに係合するようになり、建物内部側での面倒な作業をなくして、外壁材の構造躯体への取付け作業を簡単に行うことができる。
【００３３】
しかも、このように外壁材を建物外部から建物内方向への移動だけで取付け可能とすることで、既に内装部材が施工された状態にある建物完成後において、外壁材を交換する場合でも、従来のように内装部材を取り壊さずに新しい外壁材を建物外部側からワンタッチで取り付けることができ、外壁材の交換作業を簡単に済ますことができる。
【００３４】
また、付勢体によって抜け止め部材を拡張部に嵌合する方向へ付勢することで、抜け止め部材が拡張部から外れ難くなり、震動やがた付きが生じた場合でも、係止部材と棒状部材との係合状態を安定して維持して、建築材を確実に取り付けることができる。
【００３５】
さらに、ストッパによって抜け止め部材を一時的に待避位置に保持することで、係止部材と抜け止め部材との干渉をなくして、係止部材のスリットへ棒状部材をスムーズに差し入れることができ、作業性の向上を図ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a building material mounting structure and a mounting bracket, and more particularly to a mounting structure and mounting bracket for mounting an outer wall material to a structural housing such as a beam in a curtain wall structure building.
[0002]
[Prior art]
In general, in a curtain wall structure building, horizontal forces due to earthquakes and strong winds are absorbed by the shaking of the structural frame, and outer wall materials that do not support horizontal forces have a so-called locking function that rotates with the shaking of the structural frame. I am doing so.
[0003]
FIG. 8 shows an outer wall material mounting structure in the curtain wall structure building as described above. In the figure, reference numeral (50) denotes a beam constituting the structural casing, and a plate-like support plate (52) is fixed to the upper flange (51) of the beam (50) by a bolt (53).
[0004]
(54) is an outer wall member attached to the outside of the beam (50), and fasteners (55) and (56) are fixed to upper and lower ends on the back surface side of the outer wall member (54), respectively. Then, the vertical bolt (61) is inserted from the lower side into the bolt hole (60) of the upper fastener (55) in the lower outer wall material (54), and the tip of the vertical bolt (61) is supported on the beam (50) side support plate ( It is inserted into the bolt hole (62) of 52) and supported by the nut (63) screwed into the male screw portion so as not to fall downward. Further, the pin portion (65) at the tip of the vertical bolt (61) protruding upward from the support plate (52) has a pin insertion hole of the lower fastener (56) of another outer wall member (54) installed above. (64) is inserted.
[0005]
In such a mounting state, the vertical bolt (61) supporting the upper fastener (55) can slide up and down in the bolt hole (62) of the support plate (52) and move downward. Since the side fastener (56) is movable up and down along the pin part (65) of the vertical bolt (61), the outer wall material (54) (54) is obliquely following the vibration of the beam (50). It is designed to rotate so as to tilt.
[0006]
[Problems to be solved by the invention]
However, in the conventional structure described above, when the outer wall member (54) is attached, the outer wall member (54) is held in a predetermined position, and the bolt holes (60) of the support plate (52) and the upper fastener (55) ( The troublesome work of inserting the vertical bolt (61) into 62) and screwing the nut (63) into the vertical bolt (61) is necessary.
[0007]
In addition, such work is performed mainly from the inside of the building because the outer wall material (54) becomes difficult from the outside of the building and becomes difficult. For this reason, when building a new building, there is no particular problem if the outer wall material (54) is attached before constructing the interior member such as the inner wall material. When replacing the outer wall material (54), etc., the interior member has already been installed, so when installing the new outer wall material (54), a large-scale construction such as tearing down the interior member Was needed.
[0008]
This invention eliminates the above-mentioned problems, allows building materials such as outer wall materials to be easily and securely attached to a mounting body such as a structural frame, and allows easy replacement of outer wall materials after the building is completed. The purpose is to provide a mounting structure and a mounting bracket for building materials.
[0009]
[Means for Solving the Problems]

One end of the slit of the locking member is formed while moving the building material while forming a slit for penetrating the rod-shaped member with one end opened and partially expanded in the locking member. The rod-shaped member is provided with a retaining member that is fitted to an extended portion of the slit to prevent the rod-shaped member from coming off from one end of the slit when the rod-shaped member is inserted.
[0010]
The rod-shaped member is movably attached along the rod-shaped member so that the rod-shaped member is inserted through the insertion hole of the retaining member.
[0011]
The bar-shaped member is provided with a biasing body that biases the retaining member in a direction to fit the extension portion.
[0012]
Further, when a stopper is provided to hold the retaining member in a retracted position to avoid interference with the locking member, and the rod-shaped member is inserted from one end of the slit of the locking member while moving the building material Further, the stopper is released by being pushed by the locking member, so that the retention of the retaining member is released.
[0013]
Specifically, the mounted body is a structural housing such as a beam, the building material is an outer wall material, the locking member protruding from the back surface of the outer wall material, the building member along the outside direction of the building A slit is formed, one end of the building inside direction is opened, and the other end of the building outside direction is expanded.
[0014]

The horizontal piece (26) protrudes from the lower end of the vertical piece (25) toward the inside of the building. A pin insertion hole (27) is formed in the horizontal piece (26).
[0020]
(30) is a mounting bracket for attaching the outer wall materials (7) (7) to the beam (1) by engaging the fasteners (8) (9). The mounting bracket (30) includes a vertical bolt (31) as a rod-shaped member as shown in FIG. The vertical bolt (31) has a rod-shaped pin portion (32) that does not have a male screw at its tip, and the pin portion (32) faces upward and the head (33) faces downward, The nut is inserted into the bolt hole (6) of the support plate (2), and is supported by being suspended from the support plate (2) by a nut (34) screwed into the male screw portion so as not to fall downward.
[0021]
The mounting bracket (30) includes a retaining member (35) formed in a substantially cylindrical shape corresponding to the extended portion (22) of the slit (21) in the locking member (20), and the retaining member ( And a coil spring (37) as a biasing body for biasing 35) downward.
[0022]
The retaining member (35) is attached so as to be movable up and down along the vertical bolt (31) in a state where the vertical bolt (31) is inserted through the central insertion hole (38). On the upper end portion of the retaining member (35), a flange (39) projecting outward is formed.
[0023]
Similarly, the coil spring (37) is attached so as to be movable up and down along the vertical bolt (31) with the vertical bolt (31) inserted therethrough. The coil spring (37) is interposed between the support plate (2) and the retaining member (35) in a state where the vertical bolt (31) is suspended and supported by the support plate (2). In addition, (40) is a washer placed on the head (33) of the vertical bolt (31).

Then, when the locking member (20) is further pushed to a position where the extended portion (22) of the slit (21) and the retaining member (35) coincide with each other, the retaining member (35) becomes the expanded portion (22). The vertical bolt (31) that falls and fits inside the slit (21) is prevented from coming off from the open end. In addition, the head portion (33) of the vertical bolt (31) is in contact with the lower surface of the locking member (20), and the vertical bolt (31) is prevented from coming off from the slit (21). As a result, the locking member (20) is engaged with the vertical bolt (31). At this time, since the retaining member (35) is urged downward by the coil spring (37), that is, in a direction to fit into the extended portion (22), the retaining member (35) is disengaged from the expanded portion (22). It is difficult to maintain the engaged state with certainty.
[0027]
Then, after attaching the lower outer wall material (7) in this way, as shown in FIG. 1, the upper outer wall material (7) is similarly attached. The pin portion (32) of the vertical bolt (31) protruding above the support plate (2) is inserted into the pin insertion hole (27) of the lower fastener (9).
[0028]
In such a mounted state, the vertical bolt (31) for suspending the lower outer wall material (7) can slide up and down in the bolt hole (6) of the support plate (2) and move upward and downward. Since the outer wall material (7) is movable up and down along the pin portion (32) of the vertical bolt (31), the outer wall material (7) and (7) are obliquely following the vibration of the beam (1). It is tilted to rotate to allow rocking motion.
[0029]
In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of this invention.
[0030]
For example, the present invention is not limited to the mounting of the outer wall material, and may be applied to the mounting of a building material other than the inner wall material and other outer wall materials, for example. In addition, the biasing body is not limited to the coil spring, and for example, a leaf spring or rubber may be used.Also, the stopper is not limited to a halved square tube as in the above embodiment, Any shape can be used as long as the retaining member can be held in the retracted position and can be pushed and removed by the locking member. Further, for example, if the retaining member is fitted to the extended portion of the slit by its own weight or the like, the urging body may be eliminated, and as shown in FIG. If the cam surface structure is such that the stop member is automatically pushed up and moved to the retracted position, the stopper may be eliminated.
[0031]
【The invention's effect】
As described above, according to the present invention, the retaining member is automatically fitted to the extended portion of the slit only by moving the building material and inserting the rod-shaped member on the attachment body side into the slit of the locking member. Accordingly, the rod-shaped member is prevented from coming off, and the locking member and the rod-shaped member are engaged with each other. Therefore, the building material can be easily attached to the mounted body with one touch. Therefore, it is effective as a structure in which the building material is attached to the blocked part by approaching from one direction.
[0032]
In particular, this mounting structure is applied to the mounting of an outer wall material to a beam, etc., for example, by forming a slit of a locking member along the inside / outside direction of the building, and opening the end of the building inside direction side, Just by moving the outer wall material from the outside of the building toward the inside of the building, the locking member and the rod-shaped member can be engaged with each other, eliminating the troublesome work on the inside of the building, and the structural frame of the outer wall material It can be easily attached to the camera.
[0033]
In addition, by allowing the outer wall material to be attached only by moving from the outside of the building to the inside of the building in this way, even when the outer wall material is replaced after completion of the building in which the interior member has already been constructed, In this way, it is possible to attach a new outer wall material from the outside of the building with one touch without destroying the interior material, and it is possible to easily replace the outer wall material.
[0034]
In addition, by urging the retaining member in the direction to fit the expansion portion by the urging body, the retaining member becomes difficult to come off from the expansion portion, and even when vibration or rattling occurs, The building material can be securely attached by stably maintaining the engagement state with the rod-shaped member.
[0035]
Furthermore, by holding the retaining member temporarily in the retracted position by the stopper, the interference between the locking member and the retaining member can be eliminated, and the rod-shaped member can be smoothly inserted into the slit of the locking member, Workability can be improved.
