Abstract
A column and beam joint system is used to make possible the construction of a large tower such as an electrical transmission tower, which has at least three and probably four corner legs or columns which are interconnected and supported by a lattice structure of cross members. The columns have specialized channels extending substantially their full lengths and the cross members have specialized locking ends which lock into retaining structure defined in the channels, permitting braces to be inserted and locked in place at any selected point along the channel. A technique for connecting a cross member brace between a column and another cross member is also disclosed. All of the principle parts of the tower are pultruded composites which are either used in their longitudinally extended form or sectioned as required by the application. The entire tower can thus be formed of pultruded composites without the use of metal fasteners or connecting structure, enabling the tower to be made smaller and more compact, thus reducing induced EMF around the base of the tower.
