In the case of No. 8, it is necessary to join the vertically adjacent hollow panels by rotating one of the hollow panels with respect to the edge of the other hollow panel by a certain amount and then using the connecting pin. However, there is still a problem that workability is poor. Also, for example, in the case of Japanese Utility Model No. 57-32063,
Although it is relatively easy to fit the panels to each other, the work of fitting the connecting members is troublesome.

It is an object of the present invention to directly and surely connect a required number of adjacent hollow panels to each other directly and reliably by a simple operation without using bolts and nuts or connecting members having a specific shape. An object of the present invention is to provide a panel connecting device for a floor or the like.
