Composite modular mast constructing kit for streetlight, has finite length modules constituted of elements with specific length and assembled by arms, where each arm has male turns screwed with female turns in upper part of each module

摘要

The kit has finite length modules (2) assembled with each other by connection arms (6), where each module is constituted of crown segment shaped elements (7). The elements are connected with each other by engagement of a longitudinal tab (13) of one of the elements in a complementary longitudinal groove (12) of the other element and by screwing with an upper part of each arm. Each arm has groups of male turns (23) screwed with groups of female turns (17) formed inside an upper part of each module. Each element has a length of 0.80 m and an outside radius of 9 cm.
