Abstract (en)

[origin: US4345857A] A construction plate for a ditch construction device consists of profiled steel elements which are rigidly coupled with each other and covered with cover plates. At the small sides of the construction plate, profiled steel elements are provided in the form of hollow profiles which are provided with guide heads for coupling adjacent supports or construction plates. The construction plate is provided with at least one vertical hollow profile having on the inner side of the construction plate superimposed horizontal slot openings. A C- or U-shaped profiled guide bar supports horizontally-disposed joints on the rear side of its ribs which are insertable through the slot openings of the vertical throughput openings which are aligned with respect to each other, and insertable therein is a locking rod which engages the joints and/or the hollow profile with wedge elements.
