Title:
CONNECTION SECTION STRUCTURE OF LATTICE MATERIAL FOR TRUSS
Document Type and Number:
Japanese Patent JP3003770
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To simplify the connection work of lattice materials by fixing a lattice connection metal fitting on chord members which are arranged in parallel at a predetermined interval and supporting lattice materials coaxially in two directions from the lattice connection metal fitting.
SOLUTION: In a front chord member 3 and a rear chord member 4 which are arranged apart from each other and made of hollow shape material, lattice connection metal fitting fitting grooves MF, MB are formed in the front chord member 3 and the rear chord member 4. A lattice connection metal fitting 7 which is provided with a disc-shaped bearing section in the front of a base plate provided with a step section is fitted and fixed in the lattice connection metal fitting fitting grooves MF, MB. Next, a shaft insertion section of each lattice member 5 which is arranged in two directions from the lattice connection metal fitting 7 is positioned on both sides of the bearing section of the lattice connection metal fitting 7 to support the lattice member 5 in common by one shaft member. Consequently, it is possible to mount the lattice member simply and speedily.
