Description

本発明は、間仕切パネルのパネル板脱落防止装置に係わり、更に詳しくは隣接する支柱間にパネル板を装着した間仕切パネルのパネル板脱落防止装置に関するものである。 The present invention relates to a panel plate dropout prevention device for a partition panel, and more particularly to a panel plate dropout prevention device for a partition panel in which a panel plate is mounted 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。 Normally, in an office building or the like, each floor is formed by a plurality of slabs, 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, which is surrounded by structural walls. The space is appropriately partitioned by a partition device. Normally, in a suspended ceiling structure, a ceiling support rail stretched vertically and horizontally is held in a suspended shape by a suspension support member (hanging bolt) hanging from an upper slab, and the circumference of the ceiling panel is locked to the ceiling support rail. It is a structure to do. In a room having such a suspended ceiling structure, a partition device combining a partition panel and a door panel is installed from the ceiling panel to the floor structure.

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、複数の支柱を所定間隔毎に立設するとともに、該支柱の一側面又は両側面に上向き係止具を備えた係止金具を取付け、若しくは支柱の前後両面に上下方向に所定間隔で形成して係合孔に係止具を係止し、前記係止金具若しくは係止具にパネル板の両側裏板部に形成した係止孔を係止して、隣接する支柱間の表裏両面にパネル板を装着した構造の間仕切パネルは各種提供されている。 Here, the partition panel has a plurality of columns standing at predetermined intervals between the top rail fixed by using the ceiling support rail on the lower surface side of the ceiling panel and the ground rail laid on the upper surface of the floor structure. Along with the installation, a locking bracket provided with an upward locking tool is attached to one side surface or both side surfaces of the support column, or a locking tool is formed on both front and rear surfaces of the support column at predetermined intervals in the vertical direction to engage the locking tool in the engagement hole. There are various partition panels having a structure in which locking holes formed on both side back plates of the panel plate are locked to the locking metal fittings or locking tools, and panel plates are attached to both front and back surfaces between adjacent columns. It is provided.

一般的な地震振動や長周期の地震振動等によって、上下スラブ間で層間変位が生じて、支柱とパネル板が面内方向で左右に傾斜して、パネル板は左右一方の支柱に対する係止部を基準として他方が支柱に対して上方へ持ち上がることになるが、この際に前記係止金具若しくは係止具からパネル板の係止孔が外れると、当該パネル板が面外方向に倒壊することになる。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、係止金具や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、係止金具や係止具からパネル板が外れることもある。そこで、パネル板の一側が支柱に対して持ち上がっても、係止金具や係止具からパネル板が外れないように工夫した構造が特許文献１に開示されている。 Due to general seismic vibration or long-period seismic vibration, interlayer displacement occurs between the upper and lower slabs, and the column and panel plate are tilted left and right in the in-plane direction, and the panel plate is a locking part for one of the left and right columns. At this time, if the locking hole of the panel plate is disengaged from the locking bracket or the locking tool, the panel plate collapses in the out-of-plane direction. become. For example, when the support column is tilted to the right in the surface 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 reaches the position of the locking metal fitting or the locking claw of the locking tool. When raised, the panel plate may come off from the locking bracket or locking tool. Therefore, Patent Document 1 discloses a structure devised so that the panel plate does not come off from the locking metal fitting or the locking tool even if one side of the panel plate is lifted with respect to the support column.

特許文献１では、前記係止具は、前記支柱の係止孔に挿入する第１係止片と、前記パネル板の係合孔に挿入する第２係止片とを備え、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を形成して連結部を設けるとともに、該連結部の上端から第２係止片の上端からまでの長さ（Ｌ１）は、前記支柱の係止孔の上下寸法（Ｄ）の２倍以上に設定したのであるが、必然的に係止具の係止片の上下寸法が大きくなり、係合深さが深くなってパネル板の上端と天井までのクリアランスが多く必要であるので、このような手段を既設の間仕切パネルに適用することは不可能である。また、上下寸法が大きな複数の係止具に同時にパネル板の複数の係止孔を係止する作業は困難を伴う。 In Patent Document 1, the locking tool includes a first locking piece to be inserted into the locking hole of the support column and a second locking piece to be inserted into the engaging hole of the panel plate. An upward opening groove and a downward opening groove are formed between the stop piece and the second locking piece to provide a connecting portion, and the length from the upper end of the connecting portion to the upper end of the second locking piece (L1). ) Was set to be more than twice the vertical dimension (D) of the locking hole of the support column, but the vertical dimension of the locking piece of the locking tool is inevitably large and the engagement depth is deepened. Since a large clearance between the upper end of the panel plate and the ceiling is required, it is impossible to apply such means to the existing partition panel. Further, it is difficult to lock a plurality of locking holes of the panel plate at the same time to a plurality of locking tools having a large vertical dimension.

最後に、図１５及び図１６に基づいて、第５実施形態（本発明ではない）の脱落防止具６Ｅを説明する。前記脱落防止具６Ｅは、表裏に設けたパネル板４，４に形成し、前記係止金具５に係止するための係止孔１１，１１であって、対向する位置の両係止孔１１，１１の下部に、一方は密に係合し、他方は係止して表裏のパネル板４，４を連繋して面外変位を規制してなるものである。具体的には、前記脱落防止具６Ｅは、板金で製造し、基部３７に一方のパネル板４の係止孔１１の下部に密に係合する鋸歯状係合溝３８を形成し、該基部３７から対面する反対側のパネル板４の背面側に延びた連結部３９を有し、該連結部３９の先端に対面するパネル板４の係止孔１１の下部に係止する下向きフック片４０を形成し、更に前記基部３７と連結部３９の境界部分の上部に水平な把手板４１を折曲形成した構造である。 Finally, the dropout preventive device 6E of the fifth embodiment (not the present invention) will be described with reference to FIGS. 15 and 16. The dropout prevention tool 6E is a locking hole 11 or 11 formed in panel plates 4 and 4 provided on the front and back surfaces and for locking to the locking metal fitting 5, and both locking holes 11 at opposite positions. , 11 is tightly engaged on one side and locked on the other side to connect the front and back panel plates 4 and 4 to regulate out-of-plane displacement. Specifically, the fall-off prevention tool 6E is manufactured of sheet metal, and a serrated engaging groove 38 that is closely engaged with the lower portion of the locking hole 11 of one panel plate 4 is formed in the base portion 37, and the base portion is formed. A downward hook piece 40 having a connecting portion 39 extending from 37 to the back side of the panel plate 4 on the opposite side and locking to the lower part of the locking hole 11 of the panel plate 4 facing the tip of the connecting portion 39.

反対側のパネル板４は既に係止金具５に係止して支柱３に支持されている状態とする。そこで、前記脱落防止具６Ｅの鋸歯状係合溝３８をこれから係止金具５に係止するパネル板４の上下中間部に位置する係止孔１１の下部に密に噛合させて、該パネル板４の裏面に前記脱落防止具６Ｅの連結部３９が略直角に突出した状態とし、それから常法通り当該パネル板４の各係止孔１１，…を支柱３に固定した前記係止金具５，…の上向きフック片１５，…に係止すると同時に、前記脱落防止具６Ｅの先端の下向きフック片４０が対面する反対側のパネル板４の係止孔１１の下部に係止する。この状態で、表裏のパネル板４，４は互いに離れる方向の面外変位は確実に規制される。そこで、地震等の振動で前記支柱３やパネル板４が左右に面内方向に傾斜しても、表裏のパネル板４，４は傾斜に対しては同じ挙動をするので、相対的な変化は少なく、従って脱落防止具６Ｅの下向きフック片４０が係止孔１１から外れることはないのである。 The panel plate 4 on the opposite side is already locked to the locking metal fitting 5 and is supported by the support column 3. Therefore, the saw-toothed engaging groove 38 of the drop-out prevention tool 6E is closely meshed with the lower part of the locking hole 11 located in the upper and lower intermediate portions of the panel plate 4 to be locked to the locking metal fitting 5, and the panel plate is The connecting portion 39 of the drop-out prevention tool 6E is projected on the back surface of the panel 4 at a substantially right angle, and then the locking holes 11, ... Of the panel plate 4 are fixed to the support column 3 as usual. At the same time as locking to the upward hook pieces 15, ..., The downward hook pieces 40 at the tip of the drop-out prevention tool 6E are locked to the lower part of the locking hole 11 of the panel plate 4 on the opposite side facing each other. In this state, the out-of-plane displacement of the front and back panel plates 4 and 4 in the direction away from each other is surely regulated. Therefore, even if the support column 3 and the panel plate 4 are tilted to the left and right in the in-plane direction due to vibration such as an earthquake, the front and back panel plates 4 and 4 behave in the same manner with respect to the tilt, so that the relative change is Therefore, the downward hook piece 40 of the fall prevention device 6E does not come off from the locking hole 11.
