Beam for scaffold platforms, scaffold platform plane, method for forming a scaffold platform plane, and use of a beam

Abstract

A beam for scaffold platforms for forming a scaffold platform plane, comprising at least two profiles which are guided longitudinally displaceably in one another and have recesses which, in the overlapping region, form openings for the reception of scaffold platforms, wherein the shape and/or the size of the openings is variable by longitudinal displacement of the profiles relative to one another. A scaffold platform plane, a method for building a scaffold platform plane and the use of a beam.

1 . A beam for scaffold platforms for forming a scaffold platform plane, comprising at least two profiles which are guided longitudinally displaceably one in the other and have recesses which can be brought into overlap at least in certain regions and which form openings in the overlap region for the reception of scaffold platforms, wherein the shape and/or size of the openings is variable by longitudinal displacement of the profiles relative to one another. 
     
     
         2 . The beam according to  claim 1 ,
 wherein at least one profile, in which at least one further profile is guided in a longitudinally displaceable manner, is a tubular profile.   
     
     
         3 . The beam according to  claim 1 ,
 wherein at least one profile is U-shaped in cross section.   
     
     
         4 . The beam according to  claim 1 ,
 wherein the recesses for forming the openings for the reception of scaffold platforms are formed in at least two parallel side walls of the profiles and extend in each case up to an upper side of the profiles, so that the recesses are open towards the upper sides.   
     
     
         5 . The beam according to  claim 1 ,
 wherein the recesses are undercut in some areas to form the openings for the reception of scaffold platforms.   
     
     
         6 . The beam according to  claim 1 ,
 wherein the recesses formed in the profiles for the formation of openings for the reception of scaffold platforms are each undercut on one side only and, depending on the profile, it is either the right or left side of the respective recess.   
     
     
         7 . The beam according to  claim 1 ,
 wherein the profiles guided into one another are connected or can be connected via a screw.   
     
     
         8 . The beam according to  claim 1 ,
 wherein the profiles each have at least one opening for the insertion of a tool in the region of a lower side, wherein the openings can be brought into overlap at least in certain regions.   
     
     
         9 . A scaffold platform plane comprising a plurality of scaffold platforms arranged in a plane and extending parallel to one another, which are connected, via a beam extending transversely to the scaffold platforms according to  claim 1 . 
     
     
         10 . The scaffold platform plane according to  claim 9 ,
 wherein the scaffold platforms are substantially C-shaped in cross-section and/or have lateral webs with an inwardly projecting geometry, wherein the webs of one scaffold platform each engage in an undercut region of another profile of the beam.   
     
     
         11 . The scaffold platform plane according to  claim 9 ,
 wherein the two outer scaffold platforms each engage in a recess of a profile of the beam, which recess is open at the front side.   
     
     
         12 . A method for building a scaffold platform plane, in which several scaffold platforms arranged in a plane and running parallel to one another are connected, and positioned and fixed relative to one another, using a beam according to  claim 1 . 
     
     
         13 . The method according to  claim 12 ,
 wherein, after the scaffold platforms have been assembled, the beam is aligned transversely to the scaffold platforms and is placed on the scaffold platforms from below with the recesses facing upwards, so that the scaffold platforms engage in the recesses, then the profiles of the beam are displaced longitudinally relative to one another so that they are transferred from an assembly position to an end position in which the scaffold platforms engage via outer contours in undercut regions of the recesses of the profiles.   
     
     
         14 . The method according to  claim 13 ,
 wherein the profiles are fixed in their end position by means of a screw, wherein the screw automatically falls into a locking position via link-like recesses of the profiles automatically falls into a locking position when the profiles are longitudinally displaced relative to one another.   
     
     
         15 . Use of a beam according to  claim 1  for connecting a plurality of scaffold platforms arranged in a plane and extending parallel to one another, wherein the scaffold platforms are positioned and fixed relative to one another by means of the beam. 
     
     
         16 . The beam according to  claim 2 , wherein the at least one profile is an external profile and the tubular profile is a rectangular tube. 
     
     
         17 . The beam according to  claim 3 , wherein the at least one profile is an inner profile. 
     
     
         18 . The beam according to  claim 5 , wherein the undercut areas are adapted to at least one outer contour of a scaffold platform. 
     
     
         19 . The beam according to  claim 7 , wherein the screw is received in at least one elongated hole and/or in at least one link-like recess in at least one side wall of a profile. 
     
     
         20 . The scaffold platform according to  claim 9 , wherein the plurality of scaffold platforms are positioned and fixed relative to one another.
