<P>PROBLEM TO BE SOLVED: To provide a generally narrow berm around a building with a gate made of a casting as a standard product, and to enable a width to be narrowed depending on a site. <P>SOLUTION: A gate body 3 is formed of a partition face body 31 of an aluminum casting, and a temporarily assembled frame 34 of an aluminum extruded material, which surrounds the partition face body in such a manner as to constitute an outer frame therefor. A face pattern of the partition face body 31 is formed of coarse and dense parts 32 and 33. Upper and lower horizontal frames 35 of the temporarily assembled frame 34 and the coarse part 32 at the end of the partition face body 31 are cut off; the temporarily assembled frame 34 is permanently fixed after the they are cut off; and the gate body 3 is supported in a hanging state from a hinged support 1 so as to be disposed openably/closably between it and a door stop support 2. A standard product presenting an appearance of a cast gate can adapt to the width of a narrow berm on a site. Consequently, the gate for closing the berm can effectively ensure security by hindering an intruding criminal's intrusion or flight. <P>COPYRIGHT: (C)2012,JPO&INPIT |
