Abstract

Method for assembly of a shoring tower ( 26 ), which can be used for fabrication or reconstruction of buildings, comprising shoring struts ( 27 ) being connected with each other and at least one deck ( 1 )—for providing an area indented to be accessible in a shoring level (0, I, II, IV)—, wherein the deck ( 1 ) comprises at least one insertion hook ( 3 )—for hanging up on a particularly horizontal shoring strut ( 27 )—at a first front side ( 28 ) and an opposite second front side ( 29 ), characterized in that in a first step, a separate lifting and holding tool ( 20 ) being hookable in and out of a deck ( 1 ) is hooked in a deck ( 1 ) at a front side ( 28 ) of the deck ( 1 ), which is located within a first shoring level (I), preferably in an insertion position, which is provided for insertion respectively hanging up of a deck, defined by horizontal shoring struts ( 27 )—particularly two opposed shoring struts ( 27 )—in order to allow providing a horizontal area indented to be accessible, and in a second step, the lifting and holding tool ( 20 ) is hanged up on a particularly horizontal shoring strut ( 27 ) of a next higher second shoring level (II) such that the hooked in front side ( 28 ) of the deck ( 1 ) is hold by the lifting and holding tool ( 20 ) temporarily in an assembly distance ( 30 ) above the intended insertion position of the first shoring level (I) in a slanting intermediate assembly position not intended to be accessible, wherein the assembly distance ( 30 ) is particularly smaller than the distance between the first shoring level (I) and the second shoring level (II). A very easy and safe assembly and disassembly can thereby be achieved.
