Thus, the roof unit B5 of this example
According to the configuration of (B6), the ceiling edge panels 3c, 3d
(3e, 3f) is divided into two corresponding to the two room portions R1, R2 to be arranged below the roof unit B5 (B6), and both ceiling edge panels 3c,
Since the partition receiving bar 34 is interposed between 3d (3e, 3f), the middle wall panel 5c that partitions the two room portions R1 and R2 can be securely fixed to the partition receiving bar 34. Therefore, the fixation of the middle wall panel 5c to the ceiling becomes strong. Also, at the factory stage, each ceiling edge panel 3c, 3d
(3e, 3f) is replaced with the roof unit body and partition
4 are temporarily fixed with wood screws M, M,..., So if a ceiling step occurs between the adjacent roof units B5 and B6 during the construction and assembly of the unit building, the middle wall panel 5c does not become an obstacle and is divided. Ceiling panels 3c, 3d, 3e, 3
Since the temporary fixing can be released for each f, the ceiling step can be reliably and easily corrected.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and there may be changes in the design without departing from the gist of the present invention. Is also included in the present invention. For example, the fixing device for temporary fixing is not limited to a wood screw, but may be a screw, a bolt, a nail, or the like. Further, the partition wall is not limited to a bearing wall, and may be a non-bearing wall. Further, the roof unit is not limited to the wooden type, and may be a steel frame type. Similarly, the present invention can be applied not only to the roof unit using the wall method but also to the roof unit using the frame method. Further, the fixing of the ceiling margin panel is not limited to the suspension tree or the like, but may be a truss beam, a girder small wall panel, or the like. Further, in the above-described embodiment, the case where the roof unit includes two ceiling margin panels has been described. However, the present invention is not limited thereto. ,
Three roof edge panels may be attached to the roof unit. Further, instead of the partition receiving bar, the upper frame of the middle wall panel may be inserted between the two divided ceiling edge panels and fixed. Further, a surface material for a ceiling may be attached to all or a part of the lower surface of each ceiling edge panel from a factory stage in advance. Also,
If the partition is a sound-insulating partition, as shown in FIG. 15, a cushioning material 8 such as a foam or a rubber elastic body may be interposed between the partition receiving bar and the edge of the ceiling edge panel. With this configuration, the vibration transmitted through the ceiling is reduced, so that the sound insulation performance between the rooms can be further improved.

[0027]

As described above, according to the roof unit of the present invention, the ceiling margin panel is divided into a plurality of rooms corresponding to a plurality of living room portions to be arranged below the roof unit. Therefore, the partition wall that partitions the two adjacent room portions can be reliably fixed to the ceiling edge (edge edge) or the joint receiving material (the configuration according to claim 2). Therefore, the partition wall is firmly fixed. If a cushioning material is interposed between the joint receiving material and the ceiling edge panel (edge edge), the sound insulation performance of the partition wall can be further enhanced. In addition, in the configuration according to the second aspect, if each ceiling edge panel is temporarily fixed to the roof unit main body and the joint receiving member with a screw member in advance at the factory, the ceiling panel is adjacent when the unit building is constructed and assembled. If a ceiling step occurs between the roof units, the partition wall does not become an obstacle, and the temporary fixing can be released for each divided ceiling edge panel, so that the ceiling step can be easily corrected.
