<P>PROBLEM TO BE SOLVED: To provide a drain cage in which manufacturing costs/transportation costs can be reduced by preventing uselessness caused by overlapping a side net, handleability/workability is more improved and further a high strength can be obtained. <P>SOLUTION: A drain cage 10 comprises a bottom net 2 and side nets 3A, 3B, ..., and one of side surfaces is an open end 8 where any side net is not provided. Another drain cage in the same form as the drain cage 10 can be connected to the open end 8. A connecting structure 9 may also be used for the connection. In such a case, a side net 3C is provided on a surface opposed to the open end 8. The bottom net 2 and the side nets 3A, 3B, ..., can be made of welded wire nets or expand metals. <P>COPYRIGHT: (C)2013,JPO&INPIT |
