Working platform

Abstract

The invention concerns a working platform assembly for use in the interior of a tower-like building. The object of the present invention is to provide a working platform assembly which can be used in the interior of a tower-like building even if the tower is closed at the top by an upper structure thereon. According to the invention that object is attained by a scissor lattice-like carrier structure and a working platform arranged on the carrier structure. In that respect the invention is based on the that the working platform assembly according to the invention can be adapted to different inside diameters of the tower-like building by virtue of the scissor lattice-like carrier structure and can thus extend completely across the tower cross-section. That makes it possible to work on the platform assembly. The working platform assembly can be released from the tower wall by the scissor lattice-like carrier structure and fixed again in another region of the building of a different cross-section.

1 . A working platform assembly for use in the interior of a tower-like building comprising:
 a scissor lattice-like carrier structure,   a working platform arranged on the carrier structure,   wherein the carrier structure has at least three scissor lattice-like carrier arms spaced at a uniform arcuate distance,   a central carrier element to which the scissor lattice-like carrier structures are pivotably mounted in radial orientation and are radially extendable,   a plurality of mutually partially overlappling plates that form at least a portion of the working platform.   each of the plates having an opening that, extends from a central position of the plate in a radial direction towards the central carrier element.   
   
   
       2 . A working platform assembly according to  claim 1  characterized by a Tirak winch at the peripheral end of each carrier arm. 
   
   
       3 . A working platform assembly according to  claim 1  or  claim 2  characterized by an actuating element which is arranged around the central carrier element and acts on the lower scissor lattice bars bearing against the central carrier element and is arranged along the central carrier element. 
   
   
       4 . A working platform assembly according to  claim 1  characterized by a holder for attaching cables which are fixed to the wall in the interior of the tower-like building at predetermined spacings, wherein the cables are guided through the Tirak winches. 
   
   
       5 . A working platform assembly according to  claim 4  characterized by a transverse member which can be arranged releasably in a tower segment which is to be fitted in position and which co-operates with the actuating element by means of a cable and a winch.
