Apparatus for distributing concrete to concreting nozzles of a tunnel formwork

摘要

In the case of a device for lining a space behind a formwork, provided with filling openings, in tunnel or gallery construction by means of an automatic concrete pump, a radially pivotable 90 DEG pipe bend being attached to the end-face concrete conveying pipe, via which pipe bend an end pipe can be attached to the filling openings, the 90 DEG pipe bend (11) is connected to a two-armed coupling joint. The adjusting levers (15, 16) of said coupling joint are arranged coaxially with the axis of the end-side concrete conveying pipe (7.3) and the allocation of the joints is such that the first adjusting lever (15) is pivoted, by extending (arrow Y) an adjusting cylinder (18), about a joint (20) on a fixed holding bracket (19) and thus, by the second adjusting lever (16) and a lever (21) firmly coupled to the 90 DEG pipe bend (11), pivots the latter (arrow X). In this way, a simple and uncomplicated pivoting apparatus for the ''flyer'' of a concrete-distributing device can be designed. <IMAGE>
