Description

  The present invention relates to an identification tag that can easily identify a steel member that constitutes a structure, and further uses the identification tag to ship, deliver, and inspect steel members in assembling work in the field. The present invention relates to a steel member management system that manages the above.

  In the construction of a structure composed of multiple types of steel members, a list of multiple types of steel members created by a computer during shipment, delivery, inspection, and assortment work on site, or this In many cases, the steel member is managed by the paper management table that outputs the above. In this list, the type of the steel member, the welding situation, or the position information on which position of the steel member is arranged in the structure is recorded.

In the past, this list was often created manually, but because it relied on humans, it was not possible to prevent mistakes. In addition, after the steel member arrives at the site, a list may be transmitted by FAX or the like, and there is a problem that the inspection work cannot be performed for each transport unit of the steel member.
Moreover, in order to identify the steel member, for example, the member number is written on the steel member itself, and the member number is identified. However, depending on the storage state of the steel member, the member number is difficult to see because it is located on the back side. There was also a problem that confirmation took time.
Furthermore, after the steel members are delivered to the site, when moving the steel members from the material storage site to the construction site, it is necessary to arrange the materials necessary for the construction process or redo the arrangement. Sometimes delays were discovered, and backtracking work including changes to the construction process sometimes occurred.

Thus, in the management of the steel member at the construction site, a method of managing the steel member with the IC tag has been proposed. Patent Document 1 (Japanese Patent Application Laid-Open No. 2006-299747) discloses a method of attaching an IC tag to a steel member that performs a welding operation, and recording and managing information on a welding method, information on a construction status, and the like. Furthermore, a method of attaching an IC tag to a steel member using a magnet is shown.
In addition, as a management system using an IC tag, Patent Document 2 (Japanese Patent Laid-Open No. 2008-123469) discloses that an IC tag is arranged on a management target, information is read from the IC tag by a portable terminal, and the central computer is used. The configuration managed in the above is disclosed.
