Description

本発明は、耐震性間仕切装置におけるパネル板係止装置に係わり、更に詳しくは隣接する支柱間にパネル板を係止した耐震性間仕切装置におけるパネル板係止装置に関するものである。   The present invention relates to a panel plate locking device in an earthquake resistant partition device, and more particularly to a panel plate locking device in an earthquake resistant partition device in which a panel plate is locked between adjacent columns.

通常、オフィスビル等は、複数のスラブで各階が形成され、上スラブの下面側には吊り天井構造体が構築され、下スラブの上面側にはフロア構造体が構築され、構造壁で囲まれた空間を間仕切装置で適宜に区画されている。通常、吊り天井構造体は、上スラブから垂下した吊支部材（吊りボルト）によって、縦横に張り巡らした天井支持レールを吊下げ状に保持し、該天井支持レールに天井パネルの周囲を係止する構造である。このような吊り天井構造体を有する室内に天井パネルからフロア構造体にわたって、間仕切パネルやドアパネルを組み合わせた間仕切装置を設置する。ここで、間仕切パネルは、天井パネルの下面側で天井支持レールを利用して固定した天レールと、フロア構造体の上面に敷設した地レールとの間に、複数の支柱を立設するとともに、隣接する支柱間にパネル板を装着して構成する。   Normally, an office building or the like is formed of a plurality of slabs and each floor is formed, a suspended ceiling structure is constructed on the lower surface side of the upper slab, and a floor structure is constructed on the upper surface side of the lower slab and surrounded by a structural wall. The space is appropriately partitioned by a partition device. In general, a suspended ceiling structure holds a ceiling support rail suspended vertically and horizontally by suspension support members (suspending bolts) suspended from an upper slab, and locks the periphery of the ceiling panel to the ceiling support rail. It is a structure to do. A partition device combining partition panels and door panels is installed in the room having such a suspended ceiling structure from the ceiling panel to the floor structure. Here, the partition panel is provided with a plurality of support columns standing between a ceiling rail fixed using a ceiling support rail on the lower surface side of the ceiling panel and a ground rail laid on the upper surface of the floor structure, A panel board is mounted between adjacent columns.

従来、吊り天井構造体に対する耐震基準はなく、東日本大震災によって多くの吊り天井構造体が落下し、破損したことを受けて、天井の耐震性を高める機運が高まっている。従来の吊り天井構造体は、天井支持レール及び天井パネルの端部が建物の構造壁面と殆ど隙間なく接しており、建物が地震で変形した際に、天井支持レール及び天井パネルの端部が壁面に激しく衝突して破損するとともに、吊り天井構造体の水平方向変位も大きく、そのため吊り天井構造体の下に設けた間仕切パネルも端部が損傷する。特に、長周期振動による共振現象によって吊り天井構造体が水平方向に大きく変位し、あるいは建物のスラブや壁面とは異なる挙動をすることにより被害が拡大していた。体育館や劇場等の大型建築物の吊り天井構造体に対しては、吊りボルトにブレースを設けて耐震性を高めるとともに、壁や柱等の構造体と吊り天井構造体との間にクリアランスを設けて天井パネルの端部の破損を防止する等の耐震基準が提案されている。そして、新耐震基準では、層間変位角が１／６０〜１／４０、震度７、天井面加速度が２．２Ｇに耐えることが要求されている。   Conventionally, there is no seismic standard for suspended ceiling structures, and due to the fact that many suspended ceiling structures have been dropped and damaged by the Great East Japan Earthquake, the momentum for improving the earthquake resistance of the ceiling is increasing. In the conventional suspended ceiling structure, the end of the ceiling support rail and the ceiling panel are in contact with the structural wall of the building with almost no gap, and when the building is deformed by an earthquake, the end of the ceiling support rail and the ceiling panel is the wall. The suspended ceiling structure is greatly displaced in the horizontal direction, and the partition panel provided under the suspended ceiling structure is also damaged at the ends. In particular, the suspended ceiling structure is greatly displaced in the horizontal direction due to a resonance phenomenon caused by long-period vibration, or the damage is expanded due to a behavior different from that of a slab or wall of a building. For suspended ceiling structures of large buildings such as gymnasiums and theaters, bracing is provided on the suspension bolts to improve earthquake resistance, and clearance is provided between structures such as walls and pillars and suspended ceiling structures. Seismic standards have been proposed to prevent damage to the edges of ceiling panels. The new earthquake resistance standards require that the interlaminar displacement angle is 1/60 to 1/40, the seismic intensity is 7, and the ceiling acceleration is 2.2G.

従来から、地レールと天レール間に複数の支柱を所定間隔毎に立設し、隣接する支柱間にパネル板の両側縁を支持するために、該支柱の表面側とパネル板の両側裏板部に形成した係止孔に、共通の係止具を係止する構造の間仕切パネルは各種提供されている。例えば、特許文献１には、支柱に対して金属板製の係止金具を介して壁パネル（パネル板）等を着脱自在に係止する係止装置において、前記係止金具を、前記支柱の面板に穿設した縦長の係止孔に挿入して該面板内面に接当する縦長の第１係止爪と、前記支柱の外面に沿って延びる縦長の第２係止爪とを、当該両係止爪の中途高さ部位間を支持部にて繋いで、該両係止爪の間にて上下に開放する上下一対の開口溝が形成されるように構成し、この上向き開口溝に、第２係止爪に係止する壁パネル等における板状係止部を係脱自在に嵌挿し、前記支持部の下端から第１係止爪の上端までの高さ寸法を前記係止孔の上下寸法よりも大きくなるように設定し、前記第２係止爪の上端を第１係止爪の上端よりも低くすると共に、該第２係止爪における上部の内角部を切欠き形成する一方、前記下向き開口溝の溝巾寸法を、前記支柱における面板の肉厚寸法よりも大きい寸法に設定し、前記第２係止爪の下端を第１係止爪の下端よりも下方に位置させると共に、該第２係止爪の下端には、前記支柱の外面に接当する突起を一体的に造形した構造が開示されている。   Conventionally, a plurality of support columns are erected between a ground rail and a top rail at predetermined intervals, and in order to support both side edges of the panel plate between adjacent support columns, the front side of the support column and both side back plates of the panel plate Various partition panels having a structure in which a common locking tool is locked in a locking hole formed in the portion are provided. For example, in Patent Document 1, in a locking device that detachably locks a wall panel (panel plate) or the like to a support through a metal plate locking bracket, the locking bracket is attached to the column. A vertically long first locking claw that is inserted into a vertically long locking hole formed in the face plate and contacts the inner surface of the face plate, and a vertically long second locking claw that extends along the outer surface of the support column, The middle part of the locking claw is connected by a support portion, and a pair of upper and lower opening grooves are formed to open up and down between the both locking claws. A plate-like locking portion in a wall panel or the like that is locked to the second locking claw is detachably fitted, and the height dimension from the lower end of the support portion to the upper end of the first locking claw is set to the height of the locking hole. It is set to be larger than the vertical dimension, the upper end of the second locking claw is made lower than the upper end of the first locking claw, and the second locking claw While the inner corner of the portion is notched, the groove width dimension of the downward opening groove is set to be larger than the wall thickness dimension of the face plate in the support column, and the lower end of the second locking claw is locked to the first locking position. A structure is disclosed in which a protrusion that contacts the outer surface of the support column is integrally formed at the lower end of the second locking claw while being positioned below the lower end of the claw.

また、特許文献２には、壁パネルが係止具を介して支柱に係止される構造において、前記係止具には、前記支柱の面板に穿設された支柱係止孔に挿入される第１係止片と、前記壁パネルの裏板部に穿設された壁パネル係止孔に挿入される第２係止片とが備えられ、これら第１係止片と第２係止片との間に、上向き開口溝と下向き開口溝とが形成され、前記壁パネルの裏板部には、弾性変形可能な突部が少なくとも前記壁パネル係止孔の上方に設けられ、前記上下両開口溝内に、前記支柱の面板と前記壁パネルの裏板部とが重ねた状態で配置されるとき、前記突部が前記第２係止片により弾性変形可能に押圧されるように構成したことを特徴とする壁パネル係止構造が開示されている。   Further, in Patent Document 2, in a structure in which a wall panel is locked to a column via a locking tool, the locking tool is inserted into a column locking hole formed in a face plate of the column. A first locking piece; and a second locking piece to be inserted into a wall panel locking hole formed in the back plate portion of the wall panel. The first locking piece and the second locking piece. An upward opening groove and a downward opening groove are formed between the upper and lower walls, and an elastically deformable protrusion is provided at least above the wall panel locking hole on the back plate portion of the wall panel. When the face plate of the support column and the back plate portion of the wall panel are arranged in the opening groove in a state of being overlapped, the protrusion is configured to be pressed elastically deformable by the second locking piece. A wall panel locking structure is disclosed.

しかし、何れの係止具（係止金具）を用いた壁パネルの係止構造でも、通常の状態においては不意に壁パネル（パネル板）が外れることはないが、地震振動、特に長周期の地震振動によって支柱に対してパネル板が大きく上下にずれた場合、係止具の第２係止爪からパネル板の係合孔が抜ける恐れがある。例えば、間仕切パネルの面内において支柱が右側に傾斜した場合、パネル板の左側が対応する支柱に対して持ち上がり、係止具の係止爪の位置までパネル板の係合孔が上がると、係止具からパネル板が外れることもある。   However, the wall panel locking structure using any of the locking tools (locking brackets) does not cause the wall panel (panel plate) to come off unexpectedly under normal conditions. When the panel plate is greatly displaced up and down with respect to the column due to the earthquake vibration, the engagement hole of the panel plate may come off from the second locking claw of the locking tool. For example, if the support column is inclined to the right in the plane of the partition panel, the left side of the panel plate is lifted with respect to the corresponding support column, and the engagement hole of the panel plate rises to the position of the locking claw of the locking tool. The panel board may come off from the fastener.

前記パネル板７は、図４〜図８に示すように、スチール製の表面板２５の周囲を背面側に折曲して縁板部２６を形成し、両側部においては前記縁板部２６の後縁から表面板２５に平行に内向きに裏板部２７を形成し、前記縁板部２６で囲まれる表面板２５の背面に石膏ボード２８を貼着した構造となっているが、前記裏板部２７が存在すればその他はどのような構造でも良い。そして、前記パネル板７の裏板部２７には、前記支柱３の係止孔２１の高さに合せて縦長の係合孔２２，…を形成している。前記係合孔２２は、図１０（ａ）に示すように、上下端部が端部に向かってテーパー状に横幅が狭まった形状である。   As shown in FIGS. 4 to 8, the panel plate 7 bends the periphery of the steel surface plate 25 to the back side to form the edge plate portion 26, and the edge plate portion 26 is formed on both sides. A back plate portion 27 is formed inward from the rear edge in parallel to the surface plate 25, and a gypsum board 28 is adhered to the back surface of the surface plate 25 surrounded by the edge plate portion 26. Any other structure may be used as long as the plate portion 27 exists. In the back plate portion 27 of the panel plate 7, vertically long engagement holes 22,... Are formed in accordance with the height of the locking holes 21 of the support column 3. As shown in FIG. 10A, the engaging hole 22 has a shape in which the upper and lower ends are tapered toward the end and the lateral width is narrowed.

前記係止具８は、図９及び図１０（ａ）に示すように、前記支柱３の係止孔２１に挿入する第１係止片２９と、前記パネル板７の係合孔２２に挿入する第２係止片３０とを備え、これら第１係止片２９と第２係止片３０との間に上向き開口溝と下向き開口溝とを形成して連結部３１を設けた構造である。ここで、前記連結部３１の上端から第２係止片３０の上端からまでの長さ（Ｌ１）は、前記支柱６の係止孔２１の上下寸法（Ｄ）の２倍以上に設定している。前記支柱６の係止孔２１に係止した係止具８を用いて、隣接する支柱６，６の表裏両面にパネル板７，７を係止するのであるが、前記係止具８の第２係止片３０は上向きに延びており、この掛かり寸法（Ｌ１）を長く設定することにより、前記パネル板７が上方変位しても外れないようにしている。因みに、本実施形態では、前述の掛かり寸法（Ｌ１）は４７ｍｍに設定している。当然ではあるが、前記パネル板７の係合孔２２の上下寸法は、前記係止具８の第２係止片３０の上下寸法より若干大きく設定している。   As shown in FIGS. 9 and 10A, the locking tool 8 is inserted into the first locking piece 29 inserted into the locking hole 21 of the column 3 and the engaging hole 22 of the panel plate 7. And a connecting portion 31 is formed by forming an upward opening groove and a downward opening groove between the first locking piece 29 and the second locking piece 30. . Here, the length (L1) from the upper end of the connecting portion 31 to the upper end of the second locking piece 30 is set to be twice or more the vertical dimension (D) of the locking hole 21 of the support column 6. Yes. The panel plates 7 and 7 are locked to both front and back surfaces of the adjacent columns 6 and 6 by using the locking tool 8 locked to the locking hole 21 of the column 6. The two locking pieces 30 extend upward, and by setting this engagement dimension (L1) to be long, the panel plate 7 is prevented from being detached even if it is displaced upward. Incidentally, in this embodiment, the above-mentioned hook dimension (L1) is set to 47 mm. As a matter of course, the vertical dimension of the engagement hole 22 of the panel plate 7 is set slightly larger than the vertical dimension of the second locking piece 30 of the locking tool 8.

それに対して、図１０（ｂ）に示した従来の係止具８Ａでは、掛かり寸法（Ｌ２）は１０ｍｍである。ここで、係止具８Ａの基本構造は、本発明の前記係止具８と共通するので、符号の後に「Ａ」を付して説明は省略する。同様に、掛かり寸法（Ｌ２）は、連結部３１Ａの上端から第２係止片３０Ａの上端からまでの長さである。本実施形態では、前記支柱６の係止孔２１は、従来の係止具８Ａを係止するための係止孔Ａと同じ寸法とし、支柱６は従来の支柱Ａを共用できるようにしている。   On the other hand, in the conventional locking tool 8A shown in FIG. 10B, the hanging dimension (L2) is 10 mm. Here, since the basic structure of the locking tool 8A is the same as that of the locking tool 8 of the present invention, "A" is appended to the reference numeral and description thereof is omitted. Similarly, the hanging dimension (L2) is a length from the upper end of the connecting portion 31A to the upper end of the second locking piece 30A. In the present embodiment, the locking hole 21 of the column 6 has the same size as the locking hole A for locking the conventional locking tool 8A, and the column 6 can share the conventional column A. .

図２及び図３に示すように、地震により建物の上スラブＳＵと下スラブＳＤに層間変位が生じると、特にパネル構造体３の面内方向に層間変位が発生すると、前記支柱６，…とパネル板７，…は左右に傾斜する。この傾斜角度を層間変位角の最大とした１／４０とすれば、横幅が９００ｍｍのパネル板７の一側は支柱６に対して約２３ｍｍだけ上昇する。このずれによって係止具８からパネル板７が外れないように、第２係止片３０の掛かり寸法（Ｌ１）の長さを余裕を持たせて設定している。因みに、支柱６，６の間隔は１／４０の角度で傾斜しても、高々０，３ｍｍ狭くなるだけであるので、係止孔２１と係止具８のクリアランスで吸収でき、パネル板７には横方向から圧縮する応力は作用せず、また隣接するパネル板７，７間の目地幅も僅かに狭くなるだけで影響は少ない。   As shown in FIGS. 2 and 3, when an interlayer displacement occurs in the upper slab SU and lower slab SD of the building due to an earthquake, particularly when an interlayer displacement occurs in the in-plane direction of the panel structure 3, the columns 6,. The panel plates 7 are inclined to the left and right. If this inclination angle is set to 1/40, which is the maximum interlayer displacement angle, one side of the panel plate 7 having a width of 900 mm rises by about 23 mm with respect to the column 6. The length of the hanging dimension (L1) of the second locking piece 30 is set with a margin so that the panel plate 7 is not detached from the locking tool 8 due to this shift. Incidentally, even if the interval between the support columns 6 and 6 is inclined at an angle of 1/40, the distance between the support columns 6 and 6 is only reduced by 0.3 mm at most. No stress is exerted from the lateral direction, and the joint width between the adjacent panel plates 7 and 7 is only slightly narrowed, and the influence is small.

また、図３に示すように、層間変位が生じたとき、前記パネル板７の上端と天レール４の天井取付面との間に、正面視略三角形若しくは略台形、あるいは全体として鋸歯状の上部空間Ｇ３が形成されるが、この再に前記パネル板７の上端が天レール４の天井取付面、具体的にはパネル板７が天レール４の外側に重なっている構造では天井パネル１５に衝突しないように、通常状態でパネル板７の上端と天井パネル１５の間に十分な上部空間Ｇ３を設けておくことが必要である。また、震度７程度の地震では上スラブＳＵと下スラブＳＤの間隔は最大３０ｍｍ程度増減すると見積もられるので、その余裕も確保しておく必要がある。そこで、前記パネル板７の上端から前記吊り天井構造体１を構成する天井パネル１５までの間隔を５０〜９０ｍｍに設定し、好ましくは６５〜７５ｍｍに設定する。本実施形態では、前記上部空間Ｇ３の上下寸法を７０ｍｍとしている。   Further, as shown in FIG. 3, when an interlayer displacement occurs, a generally triangular or substantially trapezoidal shape or a sawtooth-like upper portion between the upper end of the panel plate 7 and the ceiling mounting surface of the top rail 4 as a whole. A space G3 is formed, but the upper end of the panel plate 7 collides with the ceiling panel 15 in the structure where the upper end of the top rail 4 is overlapped with the ceiling mounting surface of the top rail 4, specifically, the panel plate 7 overlaps the outside of the top rail 4. Therefore, it is necessary to provide a sufficient upper space G3 between the upper end of the panel plate 7 and the ceiling panel 15 in a normal state. Further, in an earthquake with a seismic intensity of about 7, it is estimated that the distance between the upper slab SU and the lower slab SD is increased or decreased by about 30 mm at the maximum, so it is necessary to secure a margin. Then, the space | interval from the upper end of the said panel board 7 to the ceiling panel 15 which comprises the said suspended ceiling structure 1 is set to 50-90 mm, Preferably it sets to 65-75 mm. In the present embodiment, the vertical dimension of the upper space G3 is 70 mm.
