CONNECTION PART STRUCTURE FOR TRUSS FRAME MATERIAL IN CURVED-SURFACE SPACE TRUSS

摘要

PROBLEM TO BE SOLVED: To eliminate need of bending a joint plate for connecting an upper chord member collected to a knot point and a ribbed metal to be connected to the joint plate for avoiding generation of a manufacturing error and a construction error caused by bending at a connection part between truss frame materials in a space truss curved to protrude upward as a whole. ;SOLUTION: An upper chord member 1 of a truss frame member 41 is bent to protrude upward at an intermediate part of two knot points adjacent to each other, so a frame structure of a space truss is curved as a whole, while axes of the upper chord members 1, 1 of the truss frame member 41 adjacent to each other on the same line are positioned on the same line between the knot points to perpendicularly cross an axis of a bundle member 6 disposed at the position of the knot point.;COPYRIGHT: (C)1997,JPO
