By the way, even in a ceiling using a spandrel, a parting material is attached to the peripheral edge portion. Here, if the parting material is attached not to the wall surface but to the field edge in the same manner as the spandrel, the vanes of the spandrel and the parting material interfere with each other. For this reason, the end of the spandrel does not fit well in the parting material, and the appearance of the ceiling deteriorates.

The present invention has been made in view of the above facts, and an object of the present invention is to provide a ceiling structure of a building in which the ceiling material can be well fitted to the parting material.

In order to achieve the above object, the ceiling structure of the building according to the first aspect of the present invention has a field edge forming a ceiling base and a strip-shaped structure by arranging a plurality of ceiling structures at predetermined intervals in a direction intersecting the longitudinal direction. One surface is used as a ceiling surface, and wings are formed at both ends in the width direction by being bent toward the side opposite to the ceiling surface side and extending outward in the width direction, and a plurality of the wings are arranged in the width direction. The adjacent wings are overlapped with each other, and the overlapped wings are attached to the lower surface of the field edge, so that the ceiling material supported by the field edge and the peripheral edge of the ceiling base are arranged. The upper plate is attached to the lower surface of the field edge, and the arranged ceiling material is inserted and arranged between the upper plate and the lower plate facing the upper plate.

In the ceiling structure of the building of the first aspect, a plurality of field edges are arranged at predetermined intervals in a direction intersecting the longitudinal direction of the field edges to form a ceiling base, and a parting line is formed at the peripheral edge of the ceiling base. The material is placed and the top plate of the parting material is attached to the underside of the field edge.

As for the ceiling material, one surface in the shape of a strip is used as the ceiling surface, and at both ends in the width direction, vanes that are bent toward the opposite side to the ceiling surface side and extend outward in the width direction are formed. It is said to be used for watermarking. The ceiling material is arranged under the field edge, and the vanes of the adjacent ceiling materials are overlapped and attached to the lower surface of the field edge. Further, the peripheral edge of the ceiling material arranged on the lower side of the field edge is inserted between the upper plate and the lower plate of the parting material and is covered by the lower plate of the parting material.

It is fixed to the field edge at the notch.

Generally, when a ceiling material for openwork is used, the joints of the ceiling are divided, and the position of the ceiling material is determined according to the joint division. Therefore, the position of the mutual interference portion between the upper plate of the parting material and the vane portion of the ceiling material changes depending on the joint division.

In the ceiling structure of the building of the second aspect, the vane portion is cut out at the longitudinal end portion of the ceiling material to form the notch portion. Therefore, even if the position of the mutual interference portion of the vane portion of the ceiling material with respect to the upper plate of the parting material changes due to the joint split, the ceiling material can be well fitted in the parting material. This makes it easy to work to improve the fit of the ceiling material to the parting material.

The ceiling structure of the building of the third aspect is the ceiling structure of the building of the first or second aspect, and the parting material is arranged in the immediate vicinity of the wall surface on the opposite side of the ceiling material to surround the ceiling base. ..

As a result, when the longitudinal end of the spandrel 50 is inserted into the storage portion 74 of the parting material 52 and covered by the lower plate 72 of the parting material 52, the vanes 54 and 56 interfere with the upper plate 70 of the parting material 52. Is prevented from doing.

Next, as the operation of the present embodiment, the attachment of the spandrel 50 and the parting material 52 to the ceiling base 38 will be described.
In the parting material 52, the longitudinal direction is along each wall 30 (side wall 30A, back wall 30B and front wall 30C), the back plate 68 is arranged so as to be in the immediate vicinity of each wall 30, and the upper plate 70 is the field edge 40. It is fixed to the lower surface and attached to the ceiling base 38. A spandrel 50 is attached to the lower surface of the field edge 40 on the ceiling base 38 to which the parting material 52 is attached.

Each of the spandrel 50s has a longitudinal direction of the frontage of the inner garage 26, is arranged along the depth direction of the inner garage 26 according to a preset joint division, and is attached to the lower surface of the field edge 40. At this time, the vane portion 56 of the spandrel 50 is fixed to the field edge 40 by a screw 40A or the like, and the outer plate portion 60A of the vane portion 54 of the spandrel 50 adjacent to the fitting portion 62A of the vane portion 56 is fitted. Locked. As a result, on the ceiling 36, the openwork joint 66 matched to the joint division is formed by the spandrel 50 attached by the field edge 40.

In the ceiling 36, the spandrel 50 on the back wall 30B side and the front wall 30C side are cut in the longitudinal direction according to the preset joint division, and the width dimension is reduced. Therefore, in the spandrel 50 on the back wall 30B side and the front wall 30C side, the vane portion 54 or the vane portion 56 on the parting material 52 side is cut off and inserted into the storage portion 74 of the parting material 52. As a result, in the spandrel 50 inserted into the parting material 52, the vanes 54 and 56 are suppressed from interfering with the upper plate 70 of the parting material 52, and the cut portion of the spandrel 50 becomes the lower plate 72 of the parting material 52. Be covered.

On the other hand, the spandrel 50 is formed with a notch 76 at the end portion in the longitudinal direction corresponding to the parting member 52 on the side wall 30A side. When the cutout portion 76 is inserted into the storage portion 74 between the upper plate 70 and the lower plate 72 of the parting material 52 at the longitudinal end portion of the spandrel 50, the vane portions 54 and 56 of the portion overlapping the upper plate 70 are formed.

On the ceiling base 38, each of the vanes 54 and 56 of the spandrel 50 and the upper plate 70 of the parting material 52 is attached to the lower surface of the field edge 40. Therefore, when the spandrel 50 with the vanes 54 and 56 left at the ends in the longitudinal direction is inserted into the storage portion 74 of the parting material 52, the vanes 54 and 56 and the upper plate 70 interfere with each other. As a result, the longitudinal end portion of the spandrel 50 cannot be inserted into the storage portion 74 of the parting material 52, or the decorative surface 50A of the spandrel 50 is distorted in the vicinity of the parting material 52, so that the peripheral portion of the ceiling 36 is formed. The appearance deteriorates (the design is impaired).

Here, a notch 76 having notched vanes 54 and 56 is formed at the longitudinal end of the spandrel 50. The cutout portion 76 prevents the wings 54 and 56 from interfering with the upper plate 70 of the parting material 52 when the end portion in the longitudinal direction of the spandrel 50 is inserted into the storage portion 74 of the parting material 52. Thereby, the longitudinal end portion of the spandrel 50 is covered with the lower plate 72 of the parting material 52. Therefore, the ceiling 36 can obtain good design even when the parting material 52 is attached to the lower side of the field edge 40 together with the spandrel 50.

Further, when the ALC panel is used as the wall 30, it becomes difficult to attach the parting material 52 to the wall 30 by screws, bolts, etc., and it is necessary to pay close attention to the mounting work and the mounting work is complicated. Become.

On the other hand, in the ceiling 36, the back plate 68 is arranged in the immediate vicinity of the wall 30 in the same manner as the parting material 52 is attached to the wall 30. Further, the parting material 52 is fixed to the lower surface of the field edge 40 and supported by the ceiling base 38. Therefore, in the ceiling 36, it is not necessary to fix the parting material 52 to the wall surface of the wall 30, and even if the ALC panel is used for the wall 30, the work for attaching the parting material 52 becomes easy, and the parting material 52 becomes easy. The workability of installation can be improved.

Further, depending on the joint division of the ceiling 36, the position where the vanes 54 and 56 of the spandrel 50 interfere with the upper plate 70 of the parting material 52 changes in the longitudinal direction of the parting material 52. At this time, since the notch portion 76 is formed in the vane portions 54 and 56 of the spandrel 50, the vane portions 54 and 56 of the spandrel 50 and the parting material 52 interfere with each other without being affected by the joint split of the ceiling 36. Can be prevented. As a result, the workability of the work of attaching the spandrel 50 to the ceiling base 38 can be further improved.

[Modification example]

In the notch 80, the upper plate 70 of the portion overlapping the vanes 54 and 56 is cut out in a substantially rectangular shape in a state where the vane 54 and the vane 56 are fitted between the spandrel 50 adjacent to each other. It is formed (see the dashed line in FIG. 7). In the parting material 52, the upper plate 70 is fixed to the lower surface of the field edge 40 by a screw 40A (not shown) between the notches 80.

In each of the spandrel 50s, the vanes 54 and 56 are inserted into the notch 80 (see FIG. 8) of the upper plate 70 when the longitudinal end is inserted into the storage portion 74 of the parting material 52. Therefore, the vanes 54 and 56 at the longitudinal end of the spandrel 50 are in contact with the lower surface of the field edge 40 without overlapping the upper plate 70 of the parting member 52. As a result, when the vanes 54 and 56 of the spandrel 50 and the upper plate 70 of the parting material 52 are attached to the lower surface of the field edge 40, even if the longitudinal end portion of the spandrel 50 is inserted into the storage portion 74 of the parting material 52, it may be inserted. It is possible to prevent the vanes 54 and 56 from interfering with the upper plate 70.

Therefore, even when the notch portion 80 is formed on the upper plate 70 of the parting material 52, the same effect as when the notch portion 76 is formed on the vane portions 54 and 56 of the spandrel 50 can be obtained.

In the present embodiment and modifications described above, a notch is formed in one of the spandrel 50 and the parting material 52. However, the configuration in which the parting material 52 is attached to the field edge 40 together with the spandrel 50 without being fixed to the wall 30 is not limited to this.

FIG. 9 shows an example of a configuration in which the parting material 52 is attached to the field edge 40 together with the spandrel 50 without fixing the parting material 52 to the wall 30 in a cross-sectional view taken along the longitudinal direction of the spandrel 50. There is.

As shown in FIG. 9, in the ceiling base 38A used for the ceiling 36 instead of the ceiling base 38, the field edge 40 on the side wall 30A (wall 30) side facing the longitudinal end of the spandrel 50 is the ceiling base 38. It is provided so as to be separated from the side wall 30A. The distance between the field edge 40 and the side wall 30A is such that the upper plate 70 can be inserted between the side wall 30A and the field edge 40 with the back plate 68 of the parting material 52 arranged in the immediate vicinity of the side wall 30A. There is.

The spandrel 50 is attached to the field edge 40 of the ceiling base 38A. In the parting material 52, the longitudinal end portion of the spandrel 50 is inserted (inserted) between the upper plate 70 and the lower plate 72 (storage portion 74) so that the back plate 68 is in the immediate vicinity of the side wall 30A. Be placed. Further, as the parting material 52, a screw 40A or the like is used, and the vanes 54 and 56 of the span drain 50 overlapping the upper plate 70 and the upper plate 70 (between the fitting portion 62A and the horizontal plate portion 62B in the vane 56). Is fastened and fixed.

As a result, the parting material 52 is supported by the ceiling base 38A via the spandrel 50 without being fixed to the side wall 30A. Further, the longitudinal end portion (end portion on the side wall 30A side) of the spandrel 50 is covered by the lower plate 72 of the parting material 52 so that interference between the vane portions 54 and 56 and the upper plate 70 of the parting material 52 is prevented. .. Therefore, in the ceiling 36 formed by the ceiling base 38A, the end portion of the spandrel 50 in the longitudinal direction can be well fitted in the parting material 52, and high designability can be obtained.

In the present embodiment and modifications described above, the longitudinal direction of the field edge 40 is the depth direction, and the longitudinal direction of the field edge receiver 42 is the frontage direction. However, the longitudinal direction of the field edge 40 may be the frontage direction, and the longitudinal direction of the field edge receiver 42 may be the depth direction. In this case, the spandrel 50 is arranged below the field edge 40 with the longitudinal direction being the depth direction. It should be done. Further, in the present embodiment and the modified example, the ceiling 36 which is substantially horizontal has been described as an example, but the ceiling may be inclined.

Further, in the present embodiment and the modified examples, the spandrel 50 in which the vane portions 54 and 56 are formed has been described as an example. However, the spandrel as a ceiling material may have a structure in which adjacent vanes are overlapped and fixed to the lower surface of the field edge, and the vanes of the spandrel may have a shape in which the vanes overlap between the adjacent spandrels. Just do it. Further, the ceiling material is not limited to the spandrel, and may be any ceiling material for watermarking.

Further, in the present embodiment and the modified example, the ceiling 36 of the inner garage 26 has been described as an example of the ceiling opened to the outside. However, the present invention may be an indoor ceiling as long as it is a ceiling using a ceiling material for opening a watermark such as a spandrel.

Further, the ceiling opened to the outside is not limited to the ceiling 36 of the inner garage 26 and the ceiling 24 of the entrance eaves 20, and the ceiling opened to the outside of the building is required to have the same fire prevention performance as the eaves and the outer wall. It can be applied to the ceiling structure in the part, the eaves and the part where the fire protection performance equivalent to the outer wall is recommended.

For example, in the ceiling structure of the present invention, the ceiling of the eaves protruding from the outer wall of the roof of the building, the first floor of the building, and the like, the pillars are used instead of the walls to open the ceiling to the outside. It can be applied to the ceiling of a small room (Alcorp) that is open to the outside by allowing a part of the outer wall to enter the room. Further, the ceiling structure of the present invention can be applied to a ceiling in a canch structure overhanging outdoors from a building such as a roof of a veranda (a covered balcony or a covered veranda) or an underfloor portion of a balcony on an upper floor.
