PROBLEM TO BE SOLVED: To propose a novel structure in the structure of consecutively installing smoke barriers having such structure that tension is applied in the lateral direction.SOLUTION: The smoke barrier structure is formed by consecutively installing at least two units of smoke barrier 2 with incombustible sheets 70. The respective units are connected via a connection part 60, and the incombustible sheets 70 are stretched with the tension applied thereto laterally. Even when the structure in which tension F1 and F2 is applied to the incombustible sheets 70 is adopted, this configuration effectively interacts loads caused by the tension F1 and F2 with each other so as to prevent inclination of members of the connection part 60, thus retaining an optimal installation state. |
