Multilevel tribune segment comprising a plurality of structural elements which are connected to one another in a detachable way, comprising two level supports arranged next to one another at a distance from one another and connected to one another via a plurality of transverse supports , and base plates which span regions formed between the level supports and the transverse supports , wherein the transverse supports each form the end faces of the tribune levels, laterally adjoin the level supports with their ends and the level supports and the transverse supports penetrate each other in the adjoining area, in each case forming a positive fit between the transverse supports and the level supports in the direction of gravity and in all horizontal directions, in particular in all directions transverse to the longitudinal extension of the transverse supports and in all horizontal directions, wherein the transverse supports and the level supports are formed such that the respective connection between them during assembly of the tribune segment is achieved by inserting projections formed on the transverse supports into receptacles for the projections , formed on the level supports , and can be cancelled by retracting the projections from the receptacles in the opposite direction when dismantling the tribune segment , wherein the transverse supports and the level supports are formed in such a way that the connection between them can be established during the assembly of the tribune segment by inserting the projections in a direction transverse to the longitudinal extension of the transverse supports into the receptacles , wherein the transverse supports each penetrate laterally into the respective level support with several projections formed at their respective ends, forming the positive fit between the transverse support and the level support in gravity direction and in all horizontal directions, in particular in all directions transverse to the longitudinal extension of the transverse support and in all horizontal directions, wherein at least two, in particular exactly two, projections , which are spaced apart from one another in a direction transverse to the longitudinal direction of the respective transverse support , are formed at the ends of the transverse supports , characterized in that the transverse supports and the level supports are formed such that, in order to establish the respective connection between the transverse support and the level support during the assembly of the tribune segment , the insertion of a first one of the at least two projections into the associated receptacle of the level support must be carried out completely or at least partially before the insertion of a second of the at least two projections into the associated receptacle of the level support , and in that the transverse supports and the level supports are formed such that the insertion of the first of the at least two projections into the receptacle associated therewith either (a) must be carried out from the top of the level support, before the insertion of the second of the at least two projections into its associated receptacle from the front of the level support or b) must be carried out from the front side of the respective level support , before the insertion of the second of the at least two projections into the receptacle associated therewith from the top side of the level support . (a) must be carried out from the top of the level support, before the insertion of the second of the at least two projections into its associated receptacle from the front of the level support or b) must be carried out from the front side of the respective level support , before the insertion of the second of the at least two projections into the receptacle associated therewith from the top side of the level support . <EOS>
