摘要

The beam is provided at one end terminal with a frontal projection for guiding the vertical displacement of an adjoining end terminal. Handlebars of a conjugated form are also provided together with the frontal projection. The other end terminal has low projecting arms for supporting another terminal after positioning and for allowing the displacement of the supported terminal for disassembly.
