Japanese Patent JP7257844

B2

To provide an aseismatic ceiling structure having a high degree of freedom of facility layout, while realizing a low cost and light weight ceiling structure with high bearing rigidity, even for a ceiling using a ceiling finishing material poor in in-plane rigidity.SOLUTION: An aseismatic ceiling structure has a suspended ceiling unit 2 suspended from an upper structure 11 of a building skeleton via a suspending member 4, and a tension unit 3 joined to an upper part of the suspended ceiling unit 2 and bearing a horizontal load of the suspended ceiling unit 2. The tension unit 3 has tension materials 31 extendedly arranged in a horizontal direction longitudinally and laterally, and end part braces 32B restraining end parts of the tension material 31 to the building skeleton. Crossing parts of the longitudinally and laterally extended tension materials 31 provide the aseismatic ceiling structure of a constitution provided in an optionally settable state without installing separate braces in an attic of a certain span as a restraining point against a horizontal force.SELECTED DRAWING: Figure 2
