T-SHAPED STEEL FRAME FOR BEAM MATERIAL AND HYBRID BEAM MATERIAL OF STEEL FRAME AND WOOD
To provide a T-shaped steel frame usable so as to further rationally constitute a hybrid beam material with high fire resistance, which is capable of being manufactured by properly corresponding to various specifications with a small environmental load, and a hybrid beam material of steel frame and wood.SOLUTION: In a T-shaped steel frame 10 for a beam material having a T-shaped cross section is formed by a longitudinal plate part 20 whose cross-sectional shape is longitudinally long so as to form a web of a long, flat steel material constituting a core part of the beam material, and a transverse plate part 30 whose cross-sectional shape is laterally long so as to form a flange of a long, flat steel material constituting the upper surface of the beam material. The longitudinal plate part 20 and the transverse plate part 30 are fixed to each other by fitting a plurality of tenons 23 provided on the upper edge side of the longitudinal plate part 20 correspondingly to a plurality of mortises 31 provided opening in a slit shape in the horizontal plate part 30 at intervals in the longitudinal direction, into the plurality of mortises 31.SELECTED DRAWING: Figure 7
【課題】より合理的に耐火性の高いハイブリット梁材を構成するように利用できるＴ字状鉄骨について、環境負荷が小さく様々な仕様に適切に対応して製造できる梁材用のＴ字状鉄骨及び鉄骨と木材のハイブリット梁材を提供する。【解決手段】梁材の芯部を構成する長尺平板状の鋼材であってウェブを形成するように断面形状が縦方向に長い縦板部２０、及び梁材の上面を構成する長尺平板状の鋼材であってフランジを形成するように断面形状が横方向に長い横板部３０によって、断面形状がＴ字形に形成された梁材用のＴ字状鉄骨１０であって、長尺方向に間隔をおいて横板部３０にスリット状に開口して設けられた複数のほぞ穴３１に、該ほぞ穴３１に対応して縦板部２０の上縁側に設けられた複数のほぞ２３が嵌められることで、縦板部２０と横板部３０とが固定されて設けられている。【選択図】図７
