TRUSS FRAME MATERIAL FOR FORMING CURVED-SURFACE FRAME

摘要

PROBLEM TO BE SOLVED: To build truss frame materials having bending deflection, torsional deflection and bending deflection and torsional deflection in joint metals in a curved-surface frame, in which the whole is formed in a curved surface by the trussed frame materials constituting a double-layer trussed frame and the flanges of the end sections of the truss frame materials are joined with the joint metals arranged at node places of the frame by bolts through splice plates. ;SOLUTION: Bending deflection, torsional deflection of bending deflection and torsional deflection are given only to an upper chord 10 and a lower chord 11 configuring the truss frame material 2, the upper chord 10 and the lower chord 11 are connected through web materials 12 and the truss frame material 2 is manufactured, or the upper chord 10 and the lower chord 11 are joined through the web materials 12 and the truss frame material 2 is assembled. Bending deflection, torsional deflection, or the bending deflection and the torsional deflection are given to the truss frame material 2, and the end sections of the upper chord 10 and the lower chord 11 of the truss frame material are united with joint metals 1 respectively.;COPYRIGHT: (C)1999,JPO
