Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for supporting an upper part of a partition panel on a ceiling of a building, and more particularly to a partition panel mounting structure capable of coping with interlayer displacement of the building during an earthquake.

[0002]

2. Description of the Related Art In order to support an upper part of a partition panel on a ceiling of a building, a runner is fixed to the ceiling of the building, and an upper part of the hollow panel is fixed to the runner by a metal fitting.

[0003]

When an earthquake occurs, interlayer displacement may occur in a building and shear stress may be applied in the panel surface direction. In the conventional partition panel mounting structure, since the upper end of the hollow panel is fixed so as not to move with respect to the ceiling, this shear stress cannot be released and the panel is easily cracked.

It is an object of the present invention to provide a partition panel mounting structure in which stress generation due to interlayer displacement is extremely small.

[0005]

A partition panel mounting structure according to the present invention is a partition panel mounting structure in which an upper end of a partition panel is mounted on a runner fixed to a ceiling of a building by a mounting bracket. Is provided with a hanging piece that hangs downward, a dovetail-shaped groove extending in the up-down direction is provided on the back surface of the partition panel, and the upper end of the back surface of the partition panel is the hanging piece of the runner. The mounting bracket is hooked to the dovetail-shaped groove, the lower part is bolted to the hanging bracket, and the upper part covers the hanging piece of the runner. It is characterized in that it is provided with a press fitting.

In such a partition panel mounting structure of the present invention, the upper part of the partition panel is mounted to the runner by sandwiching the hanging piece of the runner between the rear surface of the upper end of the partition panel and the upper part of the holding metal fitting. . This runner hanging piece restrains the movement in the direction perpendicular to the surface of the partition panel, but does not restrain the partition panel in the direction parallel to the surface of the partition panel. Therefore, even if interlayer displacement occurs in the partition panel surface direction, almost no stress is applied to the partition panel.

In the present invention, the holding metal fitting is provided with a long hole into which the bolt is inserted, and the lower end of the holding metal fitting is provided with a projecting piece projecting toward the partition panel. It is preferable that the elongated hole of the holding metal fitting extends in the vertical direction so that the protruding piece can be in a state of being in contact with the locking metal fitting and in a state of being located below the locking metal fitting. .

In the partition panel mounting structure configured as described above, when the projecting piece is brought into contact with the locking metal fitting, the distance between the upper part of the holding metal fitting and the upper back surface of the partition panel becomes small, and a thin runner hanging piece is attached. Suitable for sandwiching.

When the projecting piece is arranged below the hook metal fitting,
The distance between the upper part of the holding metal fitting and the rear surface of the upper part of the partition panel becomes large, which is suitable for sandwiching a thick runner hanging piece.
