PROBLEM TO BE SOLVED: To provide a temporary steel tower which saves time and effort in designing and constructing the same, reduces a waste material and can be installed on a relatively narrow site.SOLUTION: A temporary steel tower 11 comprises: a main tower structure 10 which is constructed by connecting a plurality of main structural units 1 in a longitudinal direction on an upper edge of a foundation unit 6; and auxiliary steel tower structures 21 and 22 which are constructed by connecting the plurality of main tower structures 1 in the longitudinal direction on the upper edges of the foundation units 6. A cross arm supporting structure 30 which is constructed by connecting a plurality of cross arm supporting units 8, 8, ... in the longitudinal direction is installed on the main tower structure 10. The main structure unit 1 has: four main column materials 2 arranged at apexes of a square in a planar view; a plurality of horizontal materials 32 and 35 as well as diagonal materials 31, 33 and 34 arranged between the main column materials 2; and connectors 3 provided at one edges of the main column materials to connect the main structure unit 1 and the other main structure unit 1. |
