Further, by securing the height dimension of the curved plate portion, even when the other member is inclined in the height direction with respect to one member, the curved plate portion is in contact with one member even when the other member is inclined in the height direction. It will always be in contact with the other member.
Therefore, the other member can be easily connected to one member in an inclined state.

Further, the curved plate portion is formed with a through hole into which a fixing member for fixing the other member and the curved plate portion is inserted, and the through hole is formed in an elongated shape in the plate width direction. It is preferable that it is.
In this way, the fixing member can be inserted through the through hole, and the workability is improved. Further, since the through holes are formed in the shape of elongated holes in the plate width direction, the mounting range of the fixing member in the plate width direction is widened, so that it is possible to correspond to various inclination angles in the lateral direction.

Further, it is preferable that a plurality of the through holes are formed at intervals in the height direction.
In this way, since the mounting range of the fixing member in the height direction is widened, it is possible to correspond to various inclination angles in the height direction.

In order to solve the above problems, the present invention is a ceiling structure including field edges and field edge receivers that intersect each other in the height direction, and connecting metal fittings that connect the field edges and the field edge receivers. The connecting metal fitting has a substrate portion fixed to either the field edge or the field edge receiver, and is curved from one end of the substrate portion toward the opposite side of the substrate portion to form the field edge and the field edge. It is characterized by including a curved plate portion fixed to either one of the field edge receivers.

According to the present invention, since the connecting metal fitting includes a curved plate portion that curves from one end of the substrate portion toward the side opposite to the substrate portion, even when the field edge is laterally inclined with respect to the field edge receiver. When the substrate portion is in contact with one of the field edge and the field edge receiver, the curved plate portion is always in contact with the other of the field edge and the field edge receiver.
Further, by ensuring the height dimension of the curved plate portion, even when the field edge is inclined in the height direction with respect to the field edge receiver, the substrate portion is in contact with one of the field edge and the field edge receiver. The curved plate portion is always in contact with the other of the field edge and the field edge receiver.

In the ceiling structure 5 shown in FIGS. 5 and 6, the field edge 2 is inclined in the lateral direction and the height direction with respect to the field edge receiver 3. The field edge 2 arranged in the center shown in FIG. 5 is orthogonal to the field edge receiver 3 in a plan view, and the two field edges 2 arranged on both the left and right sides are directed from the lower side to the upper side of the paper surface. It is inclined so as to approach the middle field edge 2. The plurality of field edge receivers 3 are arranged parallel to each other. The connecting metal fitting 1 is arranged at the intersection of the field edge 2 and the field edge receiver 3. The connecting metal fittings 1 are used in pairs at one intersection, and are arranged one by one on both sides of the field edge 2 in the width direction. As shown in FIG. 6, the field edge 2 is inclined downward from the left side to the right side of the paper in a side view.

According to the connecting metal fitting 1 of the present embodiment, the field edge 2 can be easily connected to the field edge receiver 3 in a state of being inclined in the lateral direction and the height direction. The field edge 2 can be easily connected to the field edge receiver 3 even when the field edge 2 is inclined only in the lateral direction or only in the height direction.

When constructing the ceiling structure 5, first, the field edge 2 and the field edge receiver 3 are temporarily fixed with a conventionally known clip. Next, a pair of connecting metal fittings 1 are arranged at the intersection of the field edge 2 and the field edge receiver 3, the substrate portion 11 and the field edge 2 are connected by the fixing member 4, and the curved plate portion 12 and the field are connected by the fixing member 4. The rim holder 3 is connected.

Here, as a conventionally known clip, for example, there is a clip 6 shown in FIGS. 9A and 9B. The clip 6 has a standing plate portion 61 that covers the field edge receiver 3 from the side, a bendable claw 62 formed at the upper end of the standing plate portion 61, and cutouts on the lower sides of both side portions of the standing plate portion 61. It is provided with a pair of locking pieces 63 formed of the above. The clip 6 bends the claw 62 along the upper flange 32 of the field edge receiver 3 and locks the locking piece 63 to the lip portion 23 of the field edge 2 from below, thereby forming the field edge 2 and the field edge receiver 3. 3 is connected.

As shown in FIGS. 10A and 10B, when the clip 6 is used, it is arranged so that the width direction of the clip 6 and the length direction of the field edge receiver 3 are parallel to each other. Here, when the field edge 2 and the field edge receiver 3 shown in FIG. 10A are orthogonal to each other, the width dimension of the clip 6 required to lock the pair of locking pieces 63 to the lip portion 23, respectively. Let be D1. On the other hand, when the field edge 2 is inclined laterally to the field edge receiver 3 shown in FIG. 10B, the width dimension of the clip 6 required to lock the pair of locking pieces 63 to the lip portion 23, respectively. Let be D2. In addition, in FIGS. 10A and 10B, the clip 6 is schematically drawn.

Since the width dimension D1 and the width dimension D2 have a relationship of D1 <D2, when the field edge 2 and the field edge receiver 3 shown in FIG. 10 (b) are connected by using the clip 6 shown in FIG. 10 (a). The width of the clip 6 is insufficient, and only the locking piece 63 on one side can be locked to the lip portion 23.

Can be improved. Further, since the fixing member 4 can be inserted in the state of being temporarily fixed by the clip 6, the workability is improved.

According to the present embodiment described above, since the connecting metal fitting 1 includes a curved plate portion 12 that curves from one end 11b of the substrate portion 11 toward the side opposite to the substrate portion 11, the connecting metal fitting 1 is fielded with respect to the field edge receiver 3. Even when the edge 2 is inclined in the lateral direction, when the substrate portion 11 is in contact with the field edge 2, the curved plate portion 12 is always in contact with the field edge receiver 3. Further, by securing the height dimension of the curved plate portion 12, even if the field edge 2 is inclined in the height direction with respect to the field edge receiver 3, the substrate portion 11 is curved in a state of being in contact with the field edge 2. The plate portion 12 is always in contact with the field edge receiver 3. Therefore, the field edge 2 can be easily connected to the field edge receiver 3 in an inclined state. That is, one connecting metal fitting 1 can be used for connecting the field edge 2 and the field edge receiver 3 at various angles.

By inclining the field edge 2 in the lateral direction and the height direction with respect to the field edge receiver 3, it is possible to construct a ceiling surface having a complicated shape, so that it is possible to produce a ceiling surface having excellent design. it can.

Since the field edge 2 and the field edge receiver 3 can be firmly connected by the connecting metal fitting 1, the earthquake resistance of the ceiling structure 5 can be improved.

Since a pair of connecting metal fittings 1 are arranged on both sides of the field edge 2 in the width direction, the field edge 2 and the field edge receiver 3 can be evenly connected in the width direction of the field edge 2.

Further, since the first through hole 11a is formed in the substrate portion 11, the fixing member 4 can be inserted through the first through hole 11a, and the workability is improved.
Since the second through hole 12a is formed in the curved plate portion 12, the fixing member 4 can be inserted through the second through hole 12a, and the workability is improved.
