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 【課題】メンブレン耐火工法に係る床梁構造体の載荷加熱試験に際し、床梁の下方および上方に天井材および床版等を支持する架構体に、床梁の変形に抵抗する応力が生じないようにして、床梁の変形量を適切に把握し得る試験体と試験方法を提供する。【解決手段】 床梁２の中間部を囲むように設けられる架構体５は、床梁２の上方に配置されて床梁２の上に載架される吊りフレーム６と、吊りフレーム６に吊持されて床梁２の側方に配置される床組みフレーム７とを具備する。床梁２と床組みフレーム７との間に床版４が載架され、床組みフレーム７の下側に天井材３が張設されて、架構体５、床版４および天井材３等の重量が全て床梁２に載荷される。吊りフレーム６は床梁２に対して床梁２のたわみ方向の変位を許容する節点を介して接合され、床組みフレーム７は、その長手方向中間部で分割されて床梁２のたわみ変形に追従して変位し得るように保持される。【選択図】 図１０
