Description

The present invention relates to a reinforcing structure for a panel element of a panel body, and more particularly to a reinforcing structure for a panel element of a panel body assembled from an upper panel element and a lower panel element.

When transporting large doors to the site, there are the following problems.
(A) When transporting a large door to a repair site, etc., there are height restrictions on the transport route, and it may not be possible to secure a transport route for the door body. For example, a large door may be too large to fit in an existing elevator.
(b) The larger the door, the heavier the door, which requires more manpower to lift the door during transport.

Therefore, when transporting a large door to a site, a construction method may be adopted in which door members are manufactured in separate parts at a factory and the divided door members are assembled on site. The divided door members may be pre-assembled in advance at a manufacturing factory to facilitate on-site assembly, or may be shipped as separate door members. If the split door members prepared at the manufacturing factory were to deform due to the weight of the surface material during the transportation process, there was a risk that assembly work on site would be hindered.

The technical idea of assembling a door member divided into upper and lower parts is disclosed in, for example, Patent Document 1 and Patent Document 2, but these documents mention that the divided door member may be deformed during the transportation process, and that this may cause deformation. There was no awareness that it would affect assembly work on site.
