PARTITIONING METHOD AND DEVICE

摘要

PROBLEM TO BE SOLVED: To coat an opening part 6 formed between a deck plate to form a lower surface of a ceiling and an upper part runner for a wall body securely in a simple method, and in a short construction period to be fire-resistant. SOLUTION: The upper part runner 4 is welded with a lower surface of the deck plate 2. Before installing a dry type partition plate 5, a fire-resistant member 7 having elasticity is inserted to be disposed in a compressed condition into the opening part 6 formed between the deck plate 2 and the upper part runner 4 for the wall body. The fire-resistant member 7 in the opening part 6 elastically restores after insertion to expand and deform to profile the form of the opening part 6. The inside of the opening part 6 can thus be securely sealed with the fire-resistant member 7 only.
