Description

  The present invention relates to a corner support member for packaging a plurality of rectangular panel members such as solar cell modules in a horizontal stack so that no load is applied to each panel member.

For example, a solar cell module is required to be packed compactly while being protected from being damaged by an external force when it is transported or stored from a manufacturing factory to an installation site.
On the other hand, at the installation site, it is a problem that a large amount of labor is required for processing the packaging material, and the waste of resources due to the disposable use of the packaging material has been pointed out.
In order to solve such a problem, Patent Document 1 proposes a modular insertion system that securely stores solar cell modules stacked horizontally. In this system, a molded product member, which is a small and stable individual element that can be manufactured at a low cost by integral molding of synthetic resin, is stacked to form a load removal column. Each of the individual molded product members has a load receiving support profile as a photovoltaic module mounting device on the inside, one or more tenons or tongues on the upper or lower side, and a lower or upper side. , Having one or more open cavities or grooves for receiving tenons with precise fit. Since each molded part supports the load of the individual module, a definite transport can be ensured even at high stack heights and the risk of damage to the bottom module can be eliminated. It eliminates the need for individual packaging of modules with cardboard boxes, reduces packaging costs to the minimum required as a whole, and allows individual molded parts to be sent back to the module manufacturer and reused in multiple distributions. It is.

The orthogonal wall 5 is erected so as to abut against the outer corner of the panel, and the load receiving portion 6 extends horizontally from the orthogonal wall 5 and receives the lower surface of the corner of the panel material P. The orthogonal wall 5 has a right inner surface 51 and an outer surface 52, and flat upper and lower surfaces 53 and 54. A horizontally extending inner fitting groove 55 is opened on the upper portion of the inner surface 51, and the upper surface 53 is disposed on the upper surface 53. An inward fitting piece 56 is formed between the two. A horizontally extending outer fitting groove 57 is opened at a lower portion of the outer side surface 52, and an outward fitting piece 56 is formed between the outer fitting groove 57 and the lower surface 54. The outward fitting piece 56 is placed at the bottom of the inner fitting groove 55 of the other corner support member 2 below, and the inward fitting piece 56 is placed at the outer fitting groove 57 of the other corner support member 2 above. The outward fitting pieces 56 of the corner support member 2 are horizontally fitted with the fitting recesses 37 of the lower support member 3 on the gantry 1 and the outer fitting grooves 57 are fitted with the fitting protrusions 35 of the lower support member 3. Can be fitted. The load receiving portion 6 extends horizontally from the inner side surface 51 of the orthogonal wall 5 below the inner fitting groove 55 of the orthogonal wall 5 with an interval larger than the thickness dimension of the panel material P.

  According to the corner support member 2 of the invention according to this application, it is possible to stably support the stacked rectangular panel material P while removing the load on the individual panel materials P, and to be self-supporting in a stacked state. The stability is high, and there is no fear of falling without surrounding the outer periphery with the side wall plate, and the packaging can be easily performed.
