[Effect of idea]

As explained above, the present invention uses a sanderch board and abuts the mounting edge of the joint column across the adjacent joints of the sanderch boards that make up the wall surface, and the mounting edge is attached to each sanderch board. In addition to fixing it to the board with small pitch rivets, the top and bottom ends are joined to the top and bottom chords via peel-off prevention metal fittings, and are fixed with rivets via the rim and floor iron plate, so each sanderch board are connected in series via connecting columns, and each sandwich board functions as a bracing, forming a kind of tiger structure, which allows for extremely small deflection in the long side direction under load.

In addition, the upper and lower cut ends of the sanderch board are
Since the U-shaped anti-separation fittings are fitted and joined to the upper and lower chord members, even if a force is applied to the outer plate or the board to separate due to the reaction force from the board's own warpage, vibrations during transportation can be avoided. etc., so that peeling does not extend to the entire surface.

Furthermore, the adjacent parts of the sanderch boards are sealed by the engagement of the protrusions and grooves, and the sealing of the joints to the upper and lower chords is achieved by simply filling the outer corners with sealant. It is possible to ensure a good sealing performance. The main body of the connecting column has a substantially U-shaped cross section, and after being riveted, it forms a closed-sided column, so the rigid column is large and the strength of the joint between each sanderch board can be increased. At the same time, the main body of the connecting column located inside the storage box can be used as a member for fixing the stored equipment, making it extremely strong as a storage box for heavy equipment. It has various effects such as less bending against the wall, excellent waterproof properties, easy and reliable sealing work for waterproofing, and easy manufacturing and assembly.
