CONSTRUCTION OF TENSILE CHORD BEAM ROOF STRUCTURE AND TENSILE CHORD BEAM ROOF

摘要

PURPOSE:To obtain a given bearing force by a method in which secondary parts are temporarily fixed to a large beam in a relatively slidable manner to form a stress-releasing zone, chord members connected to the large beam are tensed to introduce stresses into the large beam, the secondary parts are fixed to the large beam. CONSTITUTION:A loose-hole structure is provided for the joint between small beams 15 and 16 on both sides of a divided roof part 26 and a brace 17, and they are loosely temporarily clamped with bolts to form a stress-releasing zone Z. The beams 15 and 16 between the divided roof parts 25 and 26 are fixed. When a tension is applied to chord members connected to brackets and tension rings provided to each large beam 1, a given stress is added to the roof constituent C and the constituent C stands by itself. The beams 15 and 16 and the brace 17 which are temporarily clamped are finally fixed to the large beam 1 by clamping each bolt.
