  In the present embodiment, the push rivet 24 is used to fasten the lower end portions 31 (reinforcing rib portions 32) of the cover body 21 and the connecting plate 23. However, the present invention is not limited to this. For example, the fastening member may be fastened using a rivet other than the push rivet 24, or may be fastened using a screw or bolt. It is preferable to use a fastening member that can be fastened without a tool. Moreover, it is preferable to use the fastening member which can be fastened only by the operation | work from the surface side. Furthermore, when the headboard cover 15 needs to be replaced, it is preferable to use a detachable fastening member.

  In the present embodiment, the headboard cover 15 covers the headboard 14 in order to repair the outer surface damage of the existing headboard 14, but the headboard cover 15 decorates the appearance of the headboard 14. It may be a decorative cover or a protective cover that protects the headboard 14.

  Furthermore, in the present embodiment, the lower end portions 31 are connected using a plurality of connecting plates 23, but the lower end portions 31 are connected using a single connecting plate 23. May be. Further, the shape of the connecting plate 23 is not limited to the rectangular shape. For example, the connecting plate 23 is connected to the insertion opening through which the lattice 13 is inserted and the side of the insertion opening (in the Y-axis direction). A comb-like connecting plate 23 having an attaching / detaching slit that guides the light relative to the insertion opening may be used.

  Furthermore, in the present embodiment, no mention was made as to whether the cutting step (S1) is performed on site or off site (for example, a factory), but it may be performed on site or off site. It is also possible to bring the cut cap board cover 15 (strictly speaking, the cover main body 21) to the site. If it is the former, since the length of the headboard 14 can be measured on the spot and repair work can be performed on the spot, there exists an advantage that a series of work can be performed smoothly. On the other hand, in the latter case, there is an advantage that even a cutting tool does not need to be brought to the site, and field work can be eliminated as much as possible.
