Corner bead i.e. lower corner bead for assembling side walls of lattice-walled body shell used for containing screw driver, has outer outgrowth provided with rim for hooking tensile element to assemble corner bead with upper corner bead

摘要

The bead (2) has an outer outgrowth provided with a rim for hooking a tensile element (6) to assemble the corner bead with another corner bead i.e. upper corner bead. A projection i.e. outer projection and inner projection is provided with an asymmetrical shaped transverse retaining area (212) and being inserted into a groove (31) parallel to an edge of walls (3) of a body shell and retained by a stop of the transverse retaining area. Bottom partition is transverse to inner side partitions and outer side partitions and forms a bottom stop. An independent claim is also included for a removable mounted body shell, comprising an assembling device and corner bead.
