FORM FOR SIMPLE T-GIRDER BRIDGE

摘要

PROBLEM TO BE SOLVED: To form various simple T-girders having different diagonal angles formed at both ends with one kind of a form for a width expansion section, to cope with different diagonal angles with one kind of the form for the width expansion section and to improve the quick execution property of the work. SOLUTION: Side frames 11 are arranged at both ends of the bottom frame 10 of a width expansion section in a form 8 for a simple T-girder, and a clamp 12 for fixing the side frame 11 is arranged on the outer face of each side frame 11. A fixed frame 16 is fixed and formed integrally with the bottom frame 10 on the outside of the bottom frame 10. The clamp 12 is rotatably connected to the fixed frame 16 via a connecting shaft 17. The connecting shaft 17 is slidably inserted into an oblong hole 18 formed on the fixed frame 16 in the direction perpendicular to the side frame 11. A driving section of a wedge 22 is formed between the clamp 12 and the fixed frame 16.
