TRIANGULAR ALUMINIUM LATTICE SECTOR FOR THE CONSTRUCTION OF MASTS IN VARYING HEIGHTS WITH SUPPORTS

摘要

A latticework mast made of lightweight aluminium of triangular cross section (3). Constitution: Three main columns (1) of non standardized profile and connecting rods (2) of shaped cylindrical profile connected to the main sector with stainless screws and nuts. Assembly process: Ground construction carried out by the lever method with no need of reinforced concrete foundation, crane, and heavy duty machines. The lattice sectors are constructed in two different widths resulted from the change of the length of the reinforcement rod and the use of the same central columns. Technical features: The lattice sector is presented in varying height (20, 30, 40, 44, 50, 54, 60 metres) and is composed of two-meter, three-meter and six-meter sectors electrostatically dyed in red and white colour in conformity to the specifications dictated by civil aviation. Purposes: Support of eolic dynamic measuring equipment (norm IEC 61400-121), fixing of telecommunication and radio wave equipment and installation of signal transmission systems.
