によつて構成されている。Embodiment The diaphragm floor A is constructed by laying a plurality of steel beams 2 made of H-beams side by side on support structures 1 made of steel frames or reinforced concrete. At the same time, a structural steel plate 3 is laid on the upper flanges of the steel beams 2, 2, and the structural steel plate 3 is
It is constructed by pouring steel fiber reinforced concrete 4 on top of the concrete.
構造用鋼板３は厚さが20mm〜25mm程度のものを
使用し、鉄骨梁２，２に溶接することによつて固
定されている。 The structural steel plate 3 has a thickness of about 20 mm to 25 mm, and is fixed to the steel beams 2 by welding.
また、ダイヤフラムフロアーＡの開口部は、構
造用鋼板３の所定位置を所定大に切り抜き開口部
とする。 Further, the opening of the diaphragm floor A is an opening cut out to a predetermined size at a predetermined position of the structural steel plate 3.

短縮化が図れる。Effects of the invention This invention consists of the above-mentioned structure. The in-plane shear force of the diaphragm floor that occurs during an earthquake can be borne by the structural steel plate, and the out-of-plane shear force on the diaphragm floor can be dispersed by steel fiber reinforced concrete. This eliminates the need for reinforcing work and the installation of studs during construction, which simplifies construction, saves labor, and shortens the construction period.
