PROBLEM TO BE SOLVED: To solve a problem discovered through a fireproof test for testing whether or not a screen fitted to an opening portion of a building has fire preventive and resistive performance, and provide a fire-protection screen as a countermeasure against the problem.SOLUTION: A fire-protection screen 1 includes: right and left guide frames 3, 4 and a lower frame 5 mounted to an inner peripheral surface 20 of an opening portion 2 of a building; a screen 10 wound up and unwound along the right and left guide frames 3, 4; and a storage box 6 that accommodates the screen 10 and is mounted to the inner peripheral surface 20. On outdoor sides of the right and left guide frames 3, 4 and the lower frame 5, a heating foam material 7 is mounted to each of spaces between the right and left guide frames 3, 4 and the inner peripheral surface 20 and between the lower frame 5 and the inner peripheral surface 20. On the outdoor side of the storage box 6, the heating foam material 7 is also mounted between the storage box 6 and the inner peripheral surface 20.SELECTED DRAWING: Figure 1 |
