Description

The present invention relates to a sliding door device in an earthquake-resistant partition device, and more particularly to a sliding door device in which a sliding door is also earthquake-resistant in an earthquake-resistant partition device.

Conventionally, it is well known that a plurality of columns are provided next to each other at predetermined intervals, a panel plate is provided between the columns to form a partition wall, and a sliding door is provided in a part of the partition wall to provide an opening / closing door.

For example, as in Patent Document 1, a rail member is horizontally provided across a plurality of columns of a partition wall device, a sliding door is suspended from the rail member to enable horizontal movement, and a release portion provided between the columns is used as an entrance / exit. Sliding door devices are provided.

In addition, in response to the fact that many suspended ceiling structures fell and were damaged in the Great East Japan Earthquake, many methods for taking measures against earthquake vibrations are being studied for partition devices. In particular, due to the inter-story displacement caused by long-period seismic vibration, the panel plate of the partition device that was once lifted does not return to its original position, and the panel plate gradually lifts as it tilts left and right, and eventually the upper end of the panel plate collides with the ceiling or the panel. The other side of the board may fall off the stanchion.

Therefore, the ceiling rail and the floor structure provided between the suspended ceiling structure constructed on the lower surface side of the upper slab and the floor structure constructed on the upper surface side of the lower slab and attached to the lower surface of the suspended ceiling structure. The panel plate is engaged with the ground rail mounted on the upper surface so that it can be displaced upward on both the front and back sides or one side of the column erected at a predetermined interval with a locking tool, and in-plane with respect to the interlayer displacement of the upper and lower slabs. A seismic partition wall that can be locked and displaced by the applicant has already been provided by the applicant.

Further, as in Patent Document 2, by providing a predetermined gap between the panel plate of the partition device and the connecting member, the vertical displacement of the panel plate during an earthquake is allowed and the panel plate is prevented from rising. Seismic partitioning devices that can be used are provided.

On the other hand, even if seismic vibration countermeasures are taken only for the partition wall structure itself and the connecting portion connected at a right angle as in Patent Document 2, the rail for suspending the sliding door of the sliding door device is directly screwed to the panel plate or supported. If the panel plate is pressed with the rail by screwing it to the rail, the rail will fix multiple panel plates, and the panel plates will vibrate at the same time due to the seismic vibration of the multiple panel plates fixed by the rail, and the panel plate will be the original. It will not be possible to return to the position of.

To prevent that.

The rail member 30 is screwed to the support column 6 with a spacer member 46 interposed therebetween. The spacer member 46 is provided with an upper screw hole 47, a middle screw hole 48, and a lower screw hole 49, and an upper screw 50 is inserted through the concave screw hole 38 and the upper screw hole 47 and screwed to the spacer member 46. A lower screw 51 is inserted through the lower plate screw hole 39 and the lower screw hole 49 and screwed in the same manner. The middle screw hole 48 is screwed directly to the support column 6. A sandwich plate 52 is sandwiched between the spacer member 46 and the rail substrate 31. The sandwiching plate 52 is provided with a sandwiching plate upper screw hole 53 and a sandwiching plate lower screw hole 54, and the sandwiching plate upper screw hole 53, the recessed screw hole 38, and the upper screw hole 47 are formed by the sandwiching plate lower screw hole. The 54, the lower plate screw hole 39, and the lower screw hole 49 form a set, and screws are inserted into each set.

Further, the lateral displacement of the lower screw 51 will be described with reference to FIGS. 8 and 9. In normal times, the upper screw 50 and the lower screw 51 are connected to the joint portion 56 substantially vertically. Further, in the normal state, the upper screw 50 and the lower screw 51 are arranged at substantially the center of the concave screw hole 38 and the lower plate screw hole 39, respectively. Even if an earthquake occurs, each screw is firmly fixed, so it is unlikely that the rail member 30 will fall in principle. However, especially when rolling or long-period vibration occurs and the strut is locked and displaced, the kinetic energy generated by the displacement is concentrated on the screw, which may cause damage to the screw. Therefore, by making either the concave screw hole 38 or the lower plate screw hole 39 a horizontally long hole (in FIG. 9, the lower plate screw hole 39 is a horizontally long hole), lateral displacement of the screw is allowed. However, damage to the screws can be avoided. As shown in FIG. 9, when an earthquake occurs and the support column 6 is tilted to the left, a horizontal deflection angle θ is generated at the positions of the lower screw 51 and the upper screw 50 as compared with normal times. This deflection angle θ is absorbed by the lower screw 51 moving horizontally between the left end 60 and the right end 61 of the lower plate screw hole 39, which is a horizontally long hole, and the lower screw 51 is damaged, causing the rail member 30 to break. Prevent it from falling. The same applies when the concave screw hole 38 or the lower plate screw hole 39 is a large-diameter hole, but the upper screw 50 or the lower screw 51 can be displaced not only in the left-right direction but also in the circumferential direction.

By locking the panel plates 7 on the left and right sides of the face plate 20 of the support column 6, two panel plate end portions 58 are installed on the face plate 20, and both end portions are not in contact with each other. As a result, the space of the substantially rectangular parallelepiped formed by the end portions 58 of both panel plates and the face plate 20 is the joint portion 56, and the spacer member 46 is interposed in the joint portion 56 to sandwich the support column 6, the spacer member 46, and the joint portion 56. The plate 52 and the rail member 30 are screwed together. Here, a gap G4 is provided between the rail member 30 and the panel body, and the rail member 30 does not come into direct contact with the panel body, so that the panel body can be locked.
