PURPOSE:To device a structure which has a large preventive effect of ceiling deflection and vibration by providing a ceiling-bearing structure which bears a ceiling of the lower floor independently from the floor upstairs of a building, resulting in no use of members of a large section and constructing the building at a low cost. CONSTITUTION:A right angle is formed by butting of respective ends of two straight members, and two other straight members are arranged to be on the down grade at both ends. Respective ends of the members are supported by girths 14 via bolsters 15. A ceiling 10 is suspended by the supporting frame 1 via ceiling hangers 2. Preferably, a plurality of supporting frames 1 is provided and adjacent frames are connected by connectors. The load of the ceiling 10 is mainly supported by an axial compression strength, in the supporting frame 1, even if members of a smaller section are used for the supporting frames, deflection and vibration can be controlled to a small extent. |
