[How to build the ceiling of the storage space]
FIG. 7 is an exploded cross-sectional view illustrating the airtight sheet installation process of the first embodiment. FIG. 8 is an exploded cross-sectional view for explaining the support member attaching step of the first embodiment. FIG. 9 is an exploded cross-sectional view for explaining a second ceiling portion attaching step of the first embodiment. FIG. 10 is an exploded cross-sectional view illustrating the wallpaper setting process of the first embodiment. Hereinafter, based on FIGS. 7-10, the construction method of the ceiling of the storage space S of Example 1 is demonstrated.

  The ceiling of the storage space S of the unit building 1 includes an airtight sheet installation step for installing the airtight sheet 26, a support member attachment step for attaching a support member for supporting the airtight sheet 26, and a second ceiling portion for attaching the second ceiling portion 30. It is constructed through an attachment process and a wallpaper installation process for installing the wallpaper 35.

(Airtight sheet installation process)
The airtight sheet installation process is performed at the factory. In the airtight sheet installation step, as shown in FIG. 7, the airtight sheet 26 is attached to the corners between the ceiling material 18 and the wall portion 20 without a gap. The airtight sheet 26 may be attached to the corners between the wall 20 and the wall 20 and the corners between the wall 20 and the flooring 16.

(Support member mounting process)
The support member attaching step is performed at a factory. In the support member attaching step, as shown in FIG. 8, the receiving member 27 is attached so as to cover the airtight sheet 26 attached to the corner between the ceiling member 18 and the wall portion 20.

(Second ceiling installation process)
A 2nd ceiling part attachment process is implemented in a factory. In the second ceiling part attaching step, the second ceiling part 30 is attached to the receiving member 27 as shown in FIG. At this time, in a state where the first convex portion 32a is fitted into the first concave portion 28a and the second convex portion 32b is fitted into the second concave portion 28b, from the entrance E of the storage space S in the long side direction X, It slides toward the edge part of the building units 3 and 4, and the 3rd convex part 32c is fitted to the 3rd recessed part 28c. That is, in a state where the second ceiling portion 30 is attached to the receiving member 27, the first convex portion 32a is fitted into the first concave portion 28a, the second convex portion 32b is fitted into the second concave portion 28b, and the third The convex part 32c fits into the third concave part 28c.

  As a result, the second ceiling portion 30 is attached to the lower side of the airtight sheet 26 attached to the corners of the ceiling material 18 and the wall portion 20. In the second ceiling part attaching step, after the second ceiling part 30 is attached to the receiving member 27, the storage door receiving member 42 is attached to the ceiling joist 17 via the ceiling member 18 with a screw or the like, and the storage door 41 is attached to the storage door. It is attached to the receiving member 42. The building units 3 and 4 that have undergone the second ceiling mounting process are transported to the building site.

(Wallpaper installation process)
The wallpaper installation process is performed at the construction site. In the wallpaper setting step, the wallpaper 35 is pasted on the wall 20 as shown in FIG. At this time, the upper end portion of the wallpaper 35 is pushed into the accommodation space G using a tool such as a special spatula.

  Next, the effect | action of the ceiling structure of Example 1 and its construction method is demonstrated. The ceiling structure of Example 1 is a ceiling structure of an indoor space (storage space S). The ceiling structure includes an airtight sheet 26 that covers a corner portion between the first ceiling portion (ceiling material 18) and the wall portion 20 of the indoor space (storage space S), and the airtight sheet 26 at the corner portion. A supporting member (receiving member 27) for supporting, and a second ceiling portion 30 provided below the airtight sheet 26 are provided (FIG. 3).

  Thereby, the airtight sheet | seat 26 and support member (receiving material 27) provided in the corner of the 1st ceiling part (ceiling material 18) and the wall part 20 can be hidden by the 2nd ceiling part 30. FIG. Therefore, the interior space (housing space S) having a clean appearance and airtightness can be obtained. Further, it is not necessary to provide an airtight sheet 26 or a parting edge (around edge) at the corner between the second ceiling 30 and the wall 20.

  In the ceiling structure of the first embodiment, the second ceiling portion 30 is provided in a non-residential space (storage space S) (FIG. 3). Thereby, the ceiling of the living room space can be the first ceiling part (ceiling material 18), and the ceiling of the non-living room space (storage space S) can be the second ceiling part 30. Therefore, the appearance of the ceiling of the non-residential space (storage space S) can be made clear while increasing the ceiling height of the living room space.

  In the ceiling structure of the first embodiment, an accommodation space G in which an upper end portion of the wallpaper 35 attached to the wall portion 20 is accommodated between the end portion of the second ceiling portion 30 and the wall portion 20. (FIG. 5).

  Thereby, the upper end part of the wallpaper 35 can be made invisible to the person who is in the indoor space (storage space S). Therefore, it can be a clean indoor space (housing space S). Further, in a state where the upper end portion of the wallpaper 35 is accommodated in the accommodation space G, a slight gap can be provided between the wallpaper 35 and the end portion of the second ceiling portion 30. Therefore, it is possible to make a beautiful parting (containment) of the joint portion between the second ceiling portion 30 and the wall portion 20 to which the wallpaper 35 is attached.

  In the ceiling structure of the first embodiment, the second ceiling portion 30 is formed of a decorative board (FIG. 3). Thereby, it can be set as the indoor space (storage space S) where the appearance was clear, without performing the difficult operation | work which attaches the wallpaper 35 to the 2nd ceiling part 30. FIG.

  The method for constructing a ceiling structure according to the first embodiment is a method for constructing a ceiling structure of an indoor space (storage space S). The method for constructing the ceiling structure includes an airtight sheet installation step in which an airtight sheet 26 is installed at a corner between the first ceiling portion (ceiling material 18) and the wall portion 20 of the indoor space (storage space S); At a corner, a supporting member attaching step for attaching a supporting member (receiving member 27) for supporting the airtight sheet 26, a second ceiling portion attaching step for attaching a second ceiling portion 30 provided below the airtight sheet 26, The wallpaper 35 is affixed to the wall 20 and the wallpaper 35 accommodates the upper end of the wallpaper 35 in the accommodation space G formed between the end of the second ceiling 30 and the wall 20. Process (FIGS. 7 to 10).

  Thereby, an airtight sheet | seat attachment process, a supporting member attachment process, and a 2nd ceiling part attachment process can be implemented in a factory. Therefore, it is possible to reduce the work man-hours at the construction site and improve the productivity.

  The ceiling structure of the present invention and the construction method thereof have been described based on the first embodiment. However, the specific configuration is not limited to this embodiment, and design changes and additions are permitted without departing from the gist of the invention according to each claim of the claims.
