Abstract

PURPOSE: To ensure the light weight of a truss bridge by jointing a lower chord member and a pillar to each other with an inner slant member, constituting either of the chord member and the slant member with a pre-stress introduction member, and providing a jack and a pin connection part on a part of the members for the rigid connection thereof after erection.
CONSTITUTION: The lower chord member 4 of a long-span horizontal or angled truss beam 2 and pillars 1 at both ends thereof are connected with inner slant members 1B. Also, one of the upper chord member 3 and lower chord member 4 of the truss beam 2, and the inner slant member 1B is constituted with a pre-stress introduction member. Furthermore, a jack is provided on a part of the main structural members of the chord and slant members, and so constituted as to be freely slidable in a lengthwise direction. Also, a pin connection part and an unassembled part are provided on a part of the main structural members. After the predetermined load is applied, the connection parts are rigidly jointed. According to the aforesaid construction, a truss beam can be made lightweight.
