Description

  The present invention relates to a column slide device in an earthquake-resistant partition device, and more particularly to a column slide device in an earthquake-resistant partition device having a function of absorbing interlayer displacement and vibration of a building due to an earthquake.

  Usually, a suspended ceiling structure is often used for indoor ceilings of office buildings and the like. That is, the suspension support member (suspending bolt) suspended from the slab on the floor holds the ceiling support rod extending vertically and horizontally in a suspended manner and locks the periphery of the ceiling panel to the ceiling support rod. . When installing the partition panel from the ceiling to the floor surface in a room having such a suspended ceiling structure, the ceiling rail of the partition panel is fixed to the ceiling support rod, and the ground rail is fixed to the floor surface.

  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. 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 seismic standards require that the interlaminar displacement is 1/60 to 1/40, the seismic intensity is 7, and the input acceleration is resistant to 2.2G.

  Conventionally, various earthquake-resistant partitioning devices have been provided. For example, Patent Literature 1 includes a ceiling rail suspended from a building structure via a suspension mechanism, and a wall main body having a frame structure in which an upper end portion is supported on the ceiling rail via a fastener, A panel attached to at least one surface of the wall main body, and a floor rail provided on the floor and holding the lower end of the wall main body, the suspension mechanism for attaching the ceiling rail And a hanger member that is supported by the building structure and grips the bar material, and the bar material includes a hanging bulging portion and a rocking bulging portion that are spaced apart in the vertical direction. The hanger member is provided with a lower end bent piece at the lower end thereof, and the hanging bulge portion engages with the lower bent piece with the hanger member and the hanging bulged portion held between the hanger members. A structure is disclosed. A structure in which the side edge of the ceiling panel is locked to the lower horizontal portion of the bar material having a substantially T-shaped cross section, and the upper end of the wall body of the frame structure constituting the partition device is screwed to the lower surface of the horizontal portion; The idea is to absorb the inter-layer displacement due to the earthquake at the connecting part between the hanger member and the bar material.

  On the other hand, in Patent Document 2, one side of a seismic isolation panel plate is hinged so as to be rotatable with a hinge on both the front and back sides of a vertical frame fixed to a fixed wall directly or via a partition panel. The other side edge of the seismic isolation panel plate is bent inward at an acute angle to form an inwardly inclined surface, and the inwardly inclined surfaces are formed on both sides of the end member attached to the end of the partition panel installed in the middle. An outwardly inclined surface is formed so as to be parallel to the surface, and in order to maintain the state where the inwardly inclined surface and the outwardly inclined surface are abutted against each other, an intermediate partition panel between both seismic isolation panel plates A seismic isolation panel is disclosed in which both seismic isolation panel plates are attracted in a direction approaching each other by a magnet catch attached to a side end directly or via another member. In this case, the idea is to prevent the interlayer displacement due to the earthquake from being transmitted to the partition panel located in the middle by opening the seismic isolation panel. In addition, the partition panel itself is provided with a pressing rod elastically biased upward at the top of the support column, and the baseboard is elastically biased downward, the pressure rod is elastically pressed against the top rail, and the baseboard is It is configured to be elastically pressed against the floor surface and absorb the interlayer displacement.

  However, since the structure described in Patent Document 1 has a structure in which the ceiling structure and the partition wall are also supported by the suspension mechanism, an excessive force is applied to the suspension mechanism at the time of a large earthquake. It is expected that it will not have to be a mechanism. On the other hand, since the thing of patent document 2 is providing the displacement absorption mechanism which can be elastically deformed also in the partition panel itself provided in the middle, it becomes a large cost increase.
