PROBLEM TO BE SOLVED: To provide a fire-resistive division penetrating-section structure capable of being easily carried out, capable of being carried out without being limited by the kinds of partitioning sections partitioning a fire-preventive division and capable of easily operating the installation, extension, exchange and removal or the like of a long-sized body. SOLUTION: In the fire-resistive division penetrating-section structure penetrating opening sections by the cable racks, the long-sized bodies are inserted into the cable racks, and the whole of the opening sections are covered with thermal-expansible fire-resistive sheets while folding sections are formed to the thermal-expansible fire-resistive sheets. In the structure, the cable racks are inserted into the voids of the thermal-expansible fire-resistive sheets formed to the folding sections while fire-resistive fillers are arranged in the cable racks.
