  In the above-described method, it is necessary to attach the ceiling base material to the end of each channel member, attach the ceiling base material to the ceiling base material connection fitting, and then attach the board to the ceiling base material connection fitting. . Therefore, the operation is complicated, and it takes time to attach each member, which causes a problem that the workability is not good. Further, in particular, in recent years, it has been strongly demanded to improve the durability of the ceiling against an earthquake or the like, and it is demanded that the fixed state of each member can be maintained even if the earthquake or the like occurs.

  An object of the present invention is to provide a connection metal fitting which can improve the workability and the durability.

  The field edge connection hardware according to the present invention is a field edge connection metal for connecting a first field edge and a second field edge extending in a direction crossing the first field edge to the first field edge, And a second member attached to the first member, the first member having a plurality of fitting portions fitted from above to the first field edge and the second field edge; A plurality of holes are provided for each of the field edge and the second field edge, the first member has a hole, the second member has an insertion bend portion that is passed through the hole, and the second member is The insertion bent portion is attached to the first member in a state where the insertion bent portion is inserted into the hole and bent.

  The field edge connection metal comprises a first member provided with a plurality of fitting portions fitted from above to the first field edge and the second field edge, and a second member attached to the first member, One member has a hole through which the insertion bending portion of the second member passes. The second member is attached to the first member in a state where the insertion bent portion is inserted into the hole and bent. Therefore, in a state where each of the plurality of fitting parts of the first member is fitted to the first field edge and the second field edge, and the insertion bent part of the second member is inserted into the hole of the first member and bent Since the attachment can be performed, the attachment of the first member and the second member to the first field edge and the second field edge can be easily performed. Therefore, the workability of the work of attaching the edge connection fitting can be improved. In addition, the first member includes a plurality of fitting portions, and a plurality of fitting portions are provided for each of the first field edge and the second field edge. Therefore, since a plurality of fitting parts fit in the 1st field edge, and a plurality of fitting parts fit in the 2nd field edge, the crossing angle of the 1st field edge and the 2nd field edge is maintained Can. That is, even if an earthquake or the like occurs, the rotation of the first member and the second field edge can be suppressed, and the fixed state of each member can be maintained, so the durability of the ceiling can be enhanced.

  In addition, the insertion and bending portion may be provided in a left-right pair with respect to at least one of the first field edge and the second field edge. In this case, the insertion and bending portions are provided on both the left and right sides of the field edge, and the field edge is sandwiched between the insertion and bending portions from both sides. Therefore, since the field edge can be held more firmly by the pair of insertion bent portions, the durability of the ceiling can be further enhanced.

  In addition, each insertion bending portion may be inserted between the side surface of at least one of the first field edge and the second field edge and the edge of the hole, and may be bent outside the hole. In this case, the respective insertion and bending portions are sandwiched between the side surface of the field edge and the edge of the hole. Therefore, the second member can be easily attached by inserting and bending each insertion bent portion from below between the side surface and the edge of the hole. In addition, by inserting the respective insertion and bending portions between the side surfaces of the field edge and the edge of the hole, the respective insertion and bending portions located on the left and right sides of the field edge can be firmly held. Therefore, since the holding power to the edge can be further enhanced, the durability of the ceiling can be further enhanced.

  According to the present invention, the workability can be improved and the durability can be improved.
