When the substrate portion is in contact with one member, the curved plate portion is necessarily in contact with the other member.
In addition, by ensuring the height 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 a state where the substrate portion is in contact with the one member. It is always 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 a long hole shape in the plate width direction. It is preferable that
If it does in this way, a fixing member can be inserted through a through-hole, and workability improves. Further, since the through hole is formed in the shape of a long hole in the plate width direction, the attachment range of the fixing member in the plate width direction is widened, so that it is possible to cope with various inclination angles in the horizontal direction.

Moreover, it is preferable that a plurality of the through holes are formed at intervals in the height direction.
If it does in this way, since the attachment range of the fixing member in a height direction spreads, it can respond to various inclination angles in a height direction.

  In order to solve the above problems, the present invention is a ceiling structure comprising a field edge and a field edge receiver that intersect with each other in the height direction, and a connection fitting that connects the field edge and the field edge receiver. The connecting bracket is fixed to one of the field edge and the field edge receiver, and is curved from one end of the substrate part toward the opposite side of the substrate part, and the field edge and And a curved plate portion fixed to either one of the field edge receivers.

In addition, by securing the height dimension of the curved plate part, even when the field edge is inclined in the height direction with respect to the field edge receiver, in the state where the substrate part 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.
Therefore, it is possible to easily connect to the field edge receiver with the field edge inclined.

In the ceiling structure 5 shown in FIGS. 3 and 4, the field edge 2 and the field edge receiver 3 are orthogonal to each other in plan view and side view. The plurality of field edges 2 are arranged in parallel to each other. The plurality of field receivers 3 are also arranged in parallel to each other. The connecting metal fitting 1 is disposed at the intersection of the field edge 2 and the field edge receiver 3 (the corner where the field edge 2 and the field edge receiver 3 intersect). The connecting metal fittings 1 are used in pairs at one crossing location, and are arranged one by one on both sides of the field edge 2 in the width direction.

  The substrate portion 11 is in contact with the side surface portion 22 of the field edge 2 and is fixed by the fixing member 4. The fixing member 4 is inserted into the first through hole 11 a located on the lower side and penetrates the side surface portion 22. The curved plate portion 12 is in contact with the web 31 of the field receiver 3 and is fixed by the fixing member 4. The fixing member 4 passes through the web 31 while being inserted into the second through hole 12a that is second from the top. According to the connection fitting 1 of this embodiment, the field edge 2 and the field edge receiver 3 which are orthogonal to each other in a plan view and a side view can be easily connected.

  FIG. 5 is a plan view showing a state in which the field edge 2 inclined to the field edge receiver 3 is connected by the connecting metal fitting 1. 6 is a side view taken along the line B-B in FIG. 5. FIG. 7 is a partially enlarged view of FIG. FIG. 8 is a partially enlarged view of FIG. In the ceiling structure 5 shown in FIGS. 5 and 6, the field edge 2 is inclined laterally and in the height direction with respect to the field edge receiver 3. The field edge 2 arranged in the middle shown in FIG. 5 is orthogonal to the field edge receiver 3 in 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 in the drawing. It is inclined to approach the field edge 2 in the middle. The plurality of field receivers 3 are arranged in parallel to each other. The connecting metal fitting 1 is disposed 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 crossing location, 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 in a side view.

  As shown in FIGS. 7 and 8, the substrate portion 11 is in contact with the side surface portion 22 of the field edge 2 and is fixed by the fixing member 4. The fixing member 4 is inserted into the first through hole 11 a located on the lower side and penetrates the side surface portion 22. The curved plate portion 12 is in contact with the web 31 of the field receiver 3 and is fixed by the fixing member 4. The fixing member 4 is inserted into the second through hole 12 a that is second from the bottom and penetrates the web 31. According to the connection metal fitting 1 of this embodiment, the field edge 2 can be easily connected to the field edge receiver 3 in a state where the field edge 2 is inclined in the horizontal direction and the height direction. The field edge 2 can be easily connected to the field edge receiver 3 even in a state where the field edge 2 is inclined only in the horizontal 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 intersections between the field edge 2 and the field edge receiver 3, the substrate part 11 and the field edge 2 are connected by the fixing member 4, and the curved plate part 12 and the field edge are connected by the fixing member 4. The edge receiver 3 is connected.

  Here, as a conventionally known clip, for example, there is a clip 6 shown in FIGS. The clip 6 is formed by notching the upright plate portion 61 that covers the field edge receiver 3 from the side, the bendable claws 62 formed at the upper end of the upright plate portion 61, and the lower sides of both sides of the upright plate portion 61. And a pair of locking pieces 63 formed. The clip 6 bends the claw 62 along the upper flange 32 of the field edge receiver 3 and engages the locking piece 63 with the lip portion 23 of the field edge 2 from below, so that the field edge 2 and the field edge receiver 3 is connected.

  As shown in FIGS. 10A and 10B, when the clip 6 is used, the clip 6 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, in the case where 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. Is D1. On the other hand, when the field edge 2 is inclined in the lateral direction in the field edge receiver 3 shown in FIG. 10B, the width dimension of the clip 6 required to each engage the pair of locking pieces 63 with the lip portion 23. Is D2. 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, the clip 2 shown in FIG. 10 (a) is used to connect the field edge 2 and the field edge receiver 3 shown in FIG. 10 (b). In this case, the width dimension of the clip 6 is insufficient, and only the locking piece 63 on one side can be locked to the lip portion 23.
Therefore, when the field edge 2 is inclined in the horizontal direction at the field edge receiver 3, two clips 6 are used at one intersection. That is, the clips 6 are arranged on both sides of the field receiver 3 in the width direction, the locking piece 63 of one clip 6 is locked to one lip portion 23, and the locking piece 63 of the other clip 6 is locked to the other Locks to the lip 23. By connecting the field edge 2 and the field edge receiver 3 with the connecting bracket 1 while using the clip 6 for temporary fixing in this way, the connection force between the field edge 2 and the field edge receiver 3 is increased, and the earthquake resistance is improved. Can be improved. Moreover, since the fixing member 4 can be inserted in the state temporarily fixed with the clip 6, workability improves.

  According to the present embodiment described above, the connection fitting 1 includes the curved plate portion 12 that curves toward the opposite side of the substrate portion 11 from the one end 11b of the substrate portion 11, so Even when the edge 2 is inclined in the lateral direction, the curved plate portion 12 is always in contact with the field edge receiver 3 in a state where the substrate portion 11 is in contact with the field edge 2. Further, by ensuring the height dimension of the curved plate portion 12, even when the field edge 2 is inclined in the height direction with respect to the field edge receiver 3, the curved portion is curved in a state where the substrate section 11 is 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 connection fitting 1 can be used to connect the field edge 2 and the field edge receiver 3 at various angles.

  By tilting the field edge 2 in the horizontal direction and the height direction with respect to the field edge receiver 3, it becomes possible to construct a ceiling surface with a complicated shape, so that a ceiling surface with excellent design can be produced. it can.

  Since the connection edge 1 can firmly connect the field edge 2 and the field edge receiver 3, the earthquake resistance of the ceiling structure 5 can be improved.

  Since a pair of connecting 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.

Moreover, since the 1st through-hole 11a is formed in the board | substrate part 11, the fixing member 4 can be inserted through the 1st through-hole 11a, and workability | operativity improves.
Since the 2nd through-hole 12a is formed in the curved board part 12, the fixing member 4 can be inserted through the 2nd through-hole 12a, and workability | operativity improves.

  Since the attachment range of the fixing member 4 in the plate width direction is widened by forming the second through hole 12a in the shape of a long hole in the plate width direction, it corresponds to various inclination angles in the lateral direction of the field edge 2. Can do.

  Since the plurality of second through holes 12a are formed at intervals in the height direction, the mounting range of the fixing member 4 in the height direction is widened, so that it corresponds to various inclination angles in the height direction of the field edge 2 can do.

  As mentioned above, although embodiment of this invention was described in detail with reference to drawings, this invention is not limited to this, In the range which does not deviate from the main point of invention, it can change suitably.

  In the present embodiment, the substrate part 11 is fixed to the field edge 2 and the curved plate part 12 is fixed to the field edge receiver 3, but the present invention is not limited to this, and the substrate part 11 is fixed to the field edge receiver 3. The curved plate portion 12 may be fixed to the field edge 2.

  In the present embodiment, the substrate portion 11 is formed in a flat plate shape as a whole, but the present invention is not limited to this, and if at least a part of the substrate portion 11 is formed in a flat plate shape, a bead or the like. It may be formed in an uneven shape.
