Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure for connecting a plurality of panels.
[0002]
[Prior art]
Conventionally, for example, a panel used for partitioning a booth such as an exhibition hall includes a side frame member that forms left and right side end surfaces of the panel, and a plurality of horizontal frame members that connect these side frame members. There are a configuration in which a structural frame is formed and a panel element is embedded on the front and back surfaces of the structural frame, and a configuration in which a panel element is attached to the front and back surfaces of an internal core. Also, this type of panel is usually used as a movable partition by attaching a plurality of panels in the adjacent direction. A nut member is provided on the side frame member of one panel, and a bolt is provided from the other side frame member. By inserting a member and engaging with the nut member, adjacent panels can be connected to form a wall having a desired size. Furthermore, by providing a nut member on the left or right side frame member of the panel by welding or the like in advance, there is no need to manually hold the nut member at the mounting location, and this nut member is lost. It is also considered that two panels can be easily connected by preventing the above.
[0003]
[Problems to be solved by the invention]
However, when the nut member is attached only to the left or right side frame member of the panel as described above, it is necessary to connect the panels in consideration of the left-right direction of the panels when connecting the panels. . That is, for example, if both side panels that are adjacent to each other do not have nut members adjacent to each other, they cannot be connected to each other. The direction in which the member is attached must be determined, and one side should be adjacent to the direction having the nut member and the other side to be the direction not having the nut member.
[0004]
Accordingly, the present invention has been made paying attention to the above-described problem, and enables a quick connection without worrying about the directionality of the panel even in a movable partition that can be easily connected by attaching a nut member in advance. For the purpose.
[0005]
[Means for Solving the Problems]
In view of the above problems, the present invention comprises a structural frame having a pair of left and right side frame members that form side end surfaces and a plurality of panels each provided with a nut member inside the side frame member. A bolt member is passed through the side frame member of the panel from the inside to the outside of the panel, and the bolt member is screwed into and engaged with a screw hole of a nut member inside the side frame member of the adjacent panel. Is connected to the side frame member of the one panel, and the engagement between the bolt member and the nut member provided on the one panel is retractable. The present invention also provides a movable partition comprising a structural frame body having a pair of left and right side frame members that form side end surfaces and connecting a plurality of panels each provided with a nut member inside the side frame member. In this case, the bolt member is passed through the side frame member of one of the adjacent panels from the inside to the outside of the panel, and the bolt member is screwed into the screw hole of the nut member of the other panel to be engaged. The head of the bolt member is engaged with and connected to the side frame member of the one panel, and the engagement between the bolt member and the nut member provided on the one panel can be retracted. Thus, even in a panel structure in which a nut member is provided in advance and can be easily connected, it is possible to easily connect the panel structure without taking into consideration the directionality of the panel.
[0006]
Further, by rotating the nut member in the bolt insertion direction and retracting it, the nut member can be easily and reliably retracted only by the bolt insertion operation.
