FIRE RESISTANCE PERFORMANCE TEST PIECE OF FLOOR BEAM STRUCTURE AND FIRE RESISTANCE PERFORMANCE TEST METHOD

摘要

PROBLEM TO BE SOLVED: To provide a test piece and a test method capable of properly obtaining a deformation amount of a floor beam in such a manner not to generate a stress for resisting the deformation of a floor beam in a frame body for supporting a ceiling material, a floor slab and the like on upper and under parts of the floor beam at the time of a load heating test of the floor beam structure by a membrane fire-resisting method.;SOLUTION: A frame body 5 provided so as to surround the middle portion of a floor beam 2 includes: a suspension frame 6 arranged above a floor beam 2 and mounted on the floor beam 2; and a floor assembly frame 7 suspended by the suspension frame 6 and arranged on a lateral side of the floor beam 2. A floor slab 4 is mounted between the floor beam 2 and the floor assembly frame 7. A ceiling material 3 is stretched below the floor assembly frame 7, and a whole weight of a frame boy 5, a floor slab 4, and a ceiling material 3 or the like is loaded on the floor beam 2. The suspension frame 6 is connected to the floor beam 2 via a node which permits a displacement in a deflection direction of the floor beam 2. The floor assembly frame 7 is divided at the middle portion in the longitudinal direction so as to be held displaceable by following the distorting variation of the floor beam 2.;SELECTED DRAWING: Figure 10;COPYRIGHT: (C)2018,JPO&INPIT
