摘要： A method of forming a structural joint between a first and a second rigid element, the first element having at least one flange extending from a face thereof and having an outer end, the second element having at least one elongate groove which is substantially arcuate in cross-section provided on a face thereof, each groove having opposed edges which define an elongate opening of a dimension to permit entry of a flange into the groove, comprises placing the outer end of at least one flange into the elongate opening of the at least one groove. Then by applying sufficient external force to the first and second elements, relative movement between the elements results and the distance between the opposing faces thereof is decreased, the flange being deformed within the groove to form a portion of a coil therein having a width which is greater than the width of the elongate opening. The degree of coiling of the flange within the groove may be varied along the length of the joint. This method may be used to join a ladder rung to a ladder rail.A structural joint between a first and a second element when formed by the above method.
