Title:
CURVED-SURFACE SPACE TRUSS
Document Type and Number:
Japanese Patent JP2984201
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To eliminate need of bending a joint plate and a ribbed metal, and prevent generation of a manufacturing error and a construction error by bending an upper chord member to protrude upward at a position other than a knot point.
SOLUTION: Truss frame members 41, 42 comprising an upper chord member 1 connected to a lower chord member by a lattice member 3 are disposed in two inclined directions to a ridge center, so the truss frame members 41, 42 form a rhomboid mesh in the plan to compose a space truss which is curved to protrude upward as a whole. At the position of a knot point, a bundle member 6 is disposed to keep an interval between the upper chord member 1 and the lower chord member 2. Joint plates 7, 8 are connected to an upper end and a lower end of the bundle member 6, and the joint plate 7 on the side of the upper chord member 1 is bolted to the upper chord member 1 with a metal 9 provided with a rib to transmit shearing force between the upper chord members 1, 1. At the part of the knot point, axial line of the bundle member 6 and an axial center of the upper chord member 1 cross each other perpendicularly, thereby need of bending the joint plate 7 on the upper chord member 1 side and the metal provided with the rib is eliminated.
