A skeleton triangular tower frame structure comprising a series of vertical, horizontal and diagonal tubular members with flattened ends, joined together by means of threaded rods or studs, washers and nuts. Every three (3) vertical tubular members joined to three (3) horizontals and to three (3) diagonals, make a section which is connected to a similar section placed on a top level. There are as many sections as the tower require as per specific design. The length, diameter and thickness of the tubular members are determined by structural calculations for a given tower design loads and height. The three (3) horizontal tubular members conform an equilateral triangle of bigger section at the bottom portion of the tower and is reduced as the tower gets higher in a tapered manner. The first section of the tower is supported by a wider base formed by a tetrahedral frame for additional stability. The tubular tower members are delivered to the job site in separate short pre-manufactured members with studs, washers and nuts for easy transportation.In constructing the tower, a removable platform is placed on top of the three horizontal members that form the equilateral layer, where the erection crew can stand up to interconnect the upper sections. This procedure continues until the self-supporting tower reaches its total height, making the use of cranes or any other elevating equipment unnecessary.
