STRUT TYPE TENSION MEMBRANE STRUCTURE AND SPACE SKELETON STRUCTURE FOR IT

摘要

PROBLEM TO BE SOLVED: To allow a secondary member for supporting a membrane to be compact and simple and to facilitate initial tension introduction to the membrane. SOLUTION: Push-up support materials 6 and 6 for point-supporting a membrane 5 at a specified part of a bridge, and pull-in support materials 7 and the like for point-supporting the membrane 5 are provided zigzag. And a membrane support point is adjustable for position in the direction penetrating the membrane surface, at least on either the push-up support member 6 side or pull-in support member 7 side. Introduction of tension for the membrane 5 is performed for each zone with the push-up support member 6 and/or pull-in support member 7 after the membrane 5 is pitched above the bridge surface in non-stress state.
