The On the other hand, in the case of Patent Document 1, the main body (corresponding to the attachment device) is attached to the web surface of the steel beam, and when the outer wall panel covering the web surface of the steel beam is attached, the outer wall panel and the main body interfere with each other. . Therefore, when attaching an outer wall panel, a stanchion pole, a safety rope, etc. must be removed, and safety | security will become inadequate in the attachment operation | work of an outer wall panel.

  In addition, when attaching and detaching the attachment device 1 to and from the rigid floor hardware 5, it is not necessary to reach out to the lower surface side of the upper flange 41 of the steel beam 4, so that the operator does not get out of the body, The attachment device 1 can be attached and detached in a safe working posture.

  Here, the rigid floor hardware 5 is preferably configured so as not to protrude upward from the upper surface of the floor panel 6. By setting it as such a structure, when a user walks on the floor panel 6, it can prevent crawling to the hard floor metal fitting 5 etc. Moreover, it is preferable that the hole 53 and the plunger part 23 of the rigid floor metal fitting 5 are located below the upper surface of the panel 6, and according to this, the plunger part 23 is accidentally pushed in with a foot etc. It is possible to prevent the device 1 from being detached.

  Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the claims. For example, in this embodiment, the base body portion 21 is provided with the plunger portion 23 to prevent the main body portion 21 from coming off from the hardware on the beam (rigid floor hardware). Not what you want. A structure in which the main body portion and the metal fixture on the beam are locked by the rotation mechanism and the function of preventing the removal may be exhibited.
