Under circumstances where information devices are being updated relatively quickly in recent years, the position of horizontal beams or columnar bodies that make up spatial structures such as offices is adjusted according to changes in dimensions and shapes due to the appearance of new information devices, etc. Must.

In a conventional coupling device that couples a horizontal beam body and a columnar body, the position for fixing the horizontal beam body and the columnar body is located inside the coupling device, which causes a difficulty in construction. In particular, when the columnar body is attached or detached from a state in which the horizontal beam body is attached to a suspended ceiling or the like, the difficulty becomes remarkable. Therefore, the positions of the horizontal beam body and the columnar body must be determined in advance, which is inconvenient when the design is changed to adjust the position of the horizontal beam body or the columnar body.

In view of the above problems, an object of the present invention is to improve the workability of adjusting a spatial structure in a coupling device that couples a horizontal beam body and a columnar body.

In order to solve the above-described problems, in the present invention, the coupling device is divided into a beam-side connecting member for connecting a horizontal beam body and a column-side connecting member for connecting a columnar body, and the beam-side connecting member and the column-side connecting member. The structure which fixes a beam side connection member and a column side connection member using a fixing member from the outer side of this was provided. With such a configuration, the present invention can provide a coupling device that can improve the workability of adjusting the spatial structure of the horizontal beam body and the columnar body.

Specifically, the present invention is a coupling device that joins a columnar body extending upward from a floor and one or a plurality of horizontal beam bodies extending in the horizontal direction with respect to the floor, the beam side coupling connecting the transverse beam bodies to each other. A column-side coupling member that is detachable from the beam-side coupling member and connects the columnar body, and the beam-side coupling member connects the horizontal beam body and the beam-side coupling member. From the outside of the beam-side connecting member and the column-side connecting member, the beam-side connecting member and the column are provided by a first fixing member that fixes the first connecting portion, the beam-side connecting member, and the column-side connecting member.
