Description

  The present invention relates to a floor joint device for connecting floor portions between buildings.

  Conventionally, this type of floor joint device has a structure in which support brackets for supporting joint plates are attached to the left and right floor frames on the joint portion side to absorb different back-and-forth and left-right swinging motions due to earthquakes and the like.

However, if the left and right buildings are installed in a part where there is a pillar projecting in the joint direction on one joint part of the left and right buildings, the joint plate protrudes to the joint part when the left and right buildings swing in different longitudinal directions. There was a drawback that it crashed and was damaged.
In order to eliminate this drawback, it is necessary to provide a gap between the pillar projecting to the joint portion side. However, if the gap is provided, there is a disadvantage that the width dimension of the joint device is reduced.
