Description

  The present invention relates to a connecting device in an earthquake-resistant partition device, and more particularly, to a connecting device in an earthquake-resistant partition device that connects other partition panels at right angles using a support column of the partition panel.

  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.

  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.

  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. Various structures for connecting other partition panels at right angles using such partition panel support are also provided. For example, Patent Document 1 uses a column exposed between the panel plate locked to the column at the end and the end member provided to cover the outer surface of the column, and A structure is disclosed in which a connecting member also serving as a support is attached along the joint, the connecting member is screwed directly to the support through the joint, and a panel plate is attached to the connecting member and connected at a right angle. ing. Similarly, there is a type that uses an intermediate column of a partition device constructed in a straight line, uses a column exposed at the joint between the left and right panel plates, and connects other partition panels at a right angle.

  Due to the interlaminar displacement caused by large earthquake vibrations, especially long-period earthquake vibrations, the partitioning device is deformed so that the columns and panel plates tilt to the left and right in the in-plane direction (rocking). A large force works so that the column shifts in the vertical direction, and the column and the panel board are displaced up and down. The side of the panel board that is lifted by left and right tilts alternately changes, but if the panel board is pressed by the connecting member and braking is applied against the vertical displacement of the panel board, it will return to its original state once the panel board is lifted. In some cases, the panel plate gradually rises, and eventually the upper end of the panel plate collides with the ceiling, or the other side of the panel plate falls off the support column. In particular, in the structure in which the panel plate is locked to the support using the locking tool, the panel plate is detached from the locking tool when the panel plate is lifted.

  Here, it is preferable that the spacer member has a width that is loosely fitted to the joint portion and has a height that is thicker than the depth of the joint portion by a gap (G4).

  Furthermore, it is more preferable that the spacer member is a long member that extends vertically and has a length equivalent to that of the support column.

  The connecting device in the seismic partition device of the invention according to claim 1 as described above locks the locking tool in the locking hole formed on the surface side of the support column erected at a predetermined interval, and both sides of the panel plate. In the seismic partition device formed by engaging the engagement hole formed in the back plate portion with the locking member, the joint between the panel plate and the end member attached to the end column or the intermediate column A connecting member of another partition panel is screwed to a support column exposed between the mounted panel plates with a spacer member interposed in the joint portion, and a predetermined gap is provided between the connecting member and the panel plate. (G4) is formed, and the vertical displacement of the panel plate is allowed. Therefore, the partition device causes the support column and the panel plate to move left and right in the in-plane direction due to large earthquake vibrations, particularly interlayer displacement caused by long-period earthquake vibrations. Deforms to tilt (Rocky In this case, a large force is applied to the column so that the panel plate is displaced in the vertical direction. Even if the panel plate rises, it may return to its original position due to its own weight due to the presence of the gap (G4). it can.

  According to claim 2, since the spacer member has a width that fits loosely into the joint portion, and has a height that is thicker than the depth of the joint portion by a gap (G4), the support member and the connecting member It is possible to connect the connecting member with a spacer member interposed therebetween.

  According to the third aspect of the present invention, the spacer member is a long member that extends vertically and has a length equivalent to that of the support column. Therefore, the spacer member can be easily mounted and exists over the entire length of the support column and the connecting member. Therefore, there is no light leakage from the gap (G4).

The connecting member 62 is attached using the support column 6 that is formed and exposed to the joint portion 61, and the locking tool 8 is locked in the locking holes 64 formed in the side plates 63, 63 of the connecting member 62. And the engaging hole 22 of the panel board 7 similar to the above is locked to the locking tool 8, and the other partition panel B is connected to the end of the partition panel A at a right angle. Also in this case, although not shown, the top rail 4 and the ground rail 5 exist on the upper and lower portions of the other partition panel B. Here, as shown in FIGS. 19 and 20, a spacer member 65 is attached to the joint portion 61, and a gap G4 of about 1 mm is formed between the connecting member 62 and the panel plate 7 of the partition panel A. So that Note that the interval between the corners G4 is not limited to 1 mm, and it is sufficient that there is a minimum interval at which the vertical displacement of the panel plate 7 is not hindered by the connecting member 62. However, light leakage does not occur due to the presence of the spacer member 65.

  The spacer member 65 is a long member extending vertically, has a lateral width that fits loosely into the joint portion 61, and has a height that is about 1 mm thicker than the depth of the joint portion 61. The connecting member 62 is a long member having a length equivalent to that of the column 6 having a substantially C-shaped cross section, and mounting holes 67 are formed at predetermined intervals along the center line of the connecting plate 66. In the spacer member 65, through holes 68,... Are formed in accordance with the positions of the mounting holes 67,... And a pilot hole 69,... Is similarly formed in the center portion of the face plate 20 of the column 6 facing the joint portion 61. Forming. Then, the spacer member 65 is inserted into the joint portion 61, the connecting plate 66 of the connecting member 62 is disposed along the joint portion 61, and the fixing screw 70 is inserted through the mounting hole 67 and the through hole 68, The connecting member 62 is attached by screwing into the pilot hole 69. As shown in FIG. 16, due to the presence of the spacer member 65, a gap G <b> 4 is formed between the connecting member 62 and the panel plate 7 of the partition panel A, and the vertical displacement of the panel plate 7 is allowed. That is, the panel structure 3 is locked in the event of an earthquake, but even if the panel 7 is temporarily lifted with respect to the column 6 at that time, the panel plate 7 returns to its original position by its own weight.

  FIG. 17 is similar to FIG. 16, using the support column 6 positioned at the end of the partition panel A, connecting the other partition panels B and B on both sides, and connecting them in a T shape in plan view. The connecting members 62, 62 are connected via the spacer members 65, 65. Further, FIG. 18 uses the intermediate column 6 of the partition panels A and A connected in a straight line, and similarly inserts the spacer member 65 into the joint portion 61 of the column 6 and attaches the connecting member 62 to the other. The partition panels B are connected at right angles to form a T-shaped connection structure in plan view. FIG. 21 is an enlarged view of the connecting portion of FIG. 18, and a gap G <b> 4 is formed between the panel plates 7 and 7 of the partition panels A and A and the connecting member 62.

When the seismic partition device according to the present invention was installed in a vibration test device and tested, the panel plate 7 did not fall off from the column 6 even with a vibration corresponding to a seismic intensity 7, and the partition device itself was not damaged in appearance. It did not occur at all.
