PANEL FOR COUPLED-FAME STUFFED WITH EARTH AND ROCK, AND COUPLED-FRAME STUFFED WITH EARTH AND ROCK

摘要

PROBLEM TO BE SOLVED: To obtain a low-cost coupled-frame stuffed with earth and rocks, which is used as a structure for protecting shores, has a bottom and a lid and components of few kinds, and for which a partition panel can be dispensed with.;SOLUTION: Oblong panels for the coupled-frame are coupled with each other to form the coupled-frame using coupling structures which enables the coupling using separate coupling members. In coupling the panels, a pair of the coupling structures are arranged on short sides of the coupled-frame opposite to each other, respectively, and n pairs (n stands for natural number) of the coupling structures are arranged alternately on long sides of the coupled frame opposite to each other, respectively. In another embodiment, the panels with holed couplers whose axes are not coaxial are coupled via a bar-shaped material having a hooked part to form the coupled-frame. Further, when the coupled-frame is formed by inserting a pin into holed couplers, the alignment of the axis of the pin and that of the hole of the couplers are shifted upon inserting the pin so as to prevent the drop out of the pin while keeping the panels coupled together.;COPYRIGHT: (C)2004,JPO
