Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of a handrail for a corridor which is constructed over an adjacent building at a predetermined interval.

[0002]

2. Description of the Related Art When a large building is subjected to a large earthquake, torsion or shrinkage occurs between both ends in the horizontal direction of the building, and a large stress is concentrated at a part of the building. There was a problem that cracks were generated and the whole building was damaged.

In recent years, when constructing a building, in order to avoid the above-mentioned large concentration of stress,
The building is divided into a plurality of buildings in the horizontal direction, and the adjacent buildings are connected by a corridor or the like. However, in order to avoid the effects of horizontal sway, even if the adjacent space is narrower below, the adjacent space becomes wider as it goes upward, which is dangerous, so it is necessary to provide handrails on both sides of the connected corridor Have been.

Conventionally, as such a handrail, FIG.
0, a partially cutaway plan view of a main part in FIG. 11, and a longitudinal sectional view of a main part in FIG. That is, the first building A is adjacent to one of the buildings A and B adjacent to the building A so that the first building A can swing about the vertical axis P1 via the hinge 02 so as to be connected to each side wall 01 of the corridor on the building A side. Handrail member 03 is attached.

[0005] A second handrail member 0 is swingably connected to the other building B via a hinge 02 so as to be connected to both side walls 01 of the corridor on the building B side around a vertical axis P2.
4 are attached.

A U-shaped guide member 05 is attached to each of the upper and lower sides of the first handrail member 03 on the free end side. A second handrail member 04 is fitted in the guide member 05 so as to be movable in the horizontal direction in which the buildings A and B are opposed to each other, located outside the first handrail members 03 on both sides. .

[0007] A stopper member 06 is attached to the guide member 05, the tip of which abuts against the second handrail member 04.
The swing range of the second handrail member 04 is regulated.

A buffer rubber 07 is attached to each of the first and second handrail members 03 and 04 at different heights, and the first and second handrail members 03 and 04 come into direct contact with each other. It is configured to prevent damage.

[0009]

However, in the case of the conventional example, it is effective against two-dimensional vibrations of adjacent buildings A and B in a horizontal direction opposite to each other and a horizontal direction perpendicular thereto. However, when both buildings A and B are displaced or twisted in the vertical direction, the two buildings A and B are moved via the first and second handrail members 03 and 04.
The disadvantage is that the force is transmitted directly between the two.

The present invention has been made in view of such circumstances, and suppresses transmission of force between adjacent buildings with respect to vibration in three-dimensional directions. An object of the present invention is to effectively prevent damage to a building due to a handrail.
