PURPOSE:To secure a fireproof blocking structure in simple working procedures by constituting it with a fixed support material adjoined to an opening of a through hole installed on a wall surface, a through bolt, a fixed side fire partition plate, fireproof filler, a movable side fire partition plate, a movable side support material and a draw nut. CONSTITUTION:A through bolt 2 installed in a through hole H is pierced through a fixed support material 1 adjoined to an opening of this through hole H on a wall surface W and one side opening of the through hole H is blocked up by a fixed side fire partition plate 3. A fireproof filler 4 is filled up in a space between the fixed side fire partition plate 3 and an inner wall of the through hole H, the other side opening of the through hole H is blocked up by a movable side fire partition plate 5. There are provided with this movable side fire partition plate 5 and a draw nut 7 drawing a movable side support material 6, applied to the plate 5, nearer. In consequence, a fireproof blocking wall of constant thickness is easily formable at all times without being influenced by wall thickness.
