The invention discloses a wind power tower drum flat plate component storage and combination device which comprises two lateral supporting tools which are correspondingly arranged on a horizontal supporting surface opposite to each other and a plurality of vertical supporting tools which are arranged between the two lateral supporting tools in mutual parallel; each vertical supporting tool correspondingly supports a vertical load of one side standing flat plate component; the two lateral supporting tools support lateral component forces of all the flat plate components commonly; and any one lateral supporting tool is fixed to the horizontal supporting surface, and the other lateral supporting tool can perform free regulation on a distance between the two lateral supporting tools accordingto an amount of the stored flat plate components. The wind power tower drum flat plate component storage and combination device provided by the invention can very conveniently solve the problem of storage of the flat plate components with long size, large weight and special structure.
