  As shown in FIGS. 1 and 2A, the worker first fixes a plurality (two in the present embodiment) of the fixing members 50 in the open state at predetermined positions on the mounting surface 48. Specifically, the screw 46 is passed through the screw hole 62 formed in the bottom plate 56 of the fixing member 50, and the fixing member 50 is screwed to the mounting surface 48.

  Next, as illustrated in FIG. 2B, the reinforcing member 76 is disposed on the side opposite to the attachment surface 48 of the header 12 and is inserted between the sandwiching portions 52.

  Next, as shown in FIG. 2C, when the header 12 is pressed against the base end portion 52A of the sandwiching portion 52 and pushed toward the base portion 54 side, the leading end portion 52B of the sandwiching portion 52 rotates in the approaching direction. To do. Then, the distal end portions 52B of the pair of sandwiching portions 52 approach each other, the distal end support portion 53 sandwiches the reinforcing portion 80 of the reinforcing member 76 from both sides, and a flange is provided between the distal end portion 52B of the sandwiching portion 52 and the header 12. Part 78 is sandwiched. 4 and 5A and 5B, the engagement piece 70 is engaged with the engagement hole 72, the header 12 is sandwiched between the sandwiching portions 52, and the sandwiching portion 52 is closed. It becomes. At this time, the reinforcing member 76 is supported by being arranged in the reinforcing space R1 with the outer surface of the reinforcing portion 80 being in contact with the tip support portion 53. As a result, the header 12 is fixed in a state of being separated from the mounting surface 48.

  When the reinforcing member 76 is disposed and reinforced on the mounting surface 48 side (base 54 side) of the header 12, the reinforcing member 76 is attached to the mounting surface 48 side of the header 12 as shown in FIG. And the reinforcing member 76 is inserted between the sandwiching portions 52 as shown in FIG.

  Next, as shown in FIG. 6C, the reinforcing portion 80 of the reinforcing member 76 protrudes from between the base end portions 52A of the pair of spaced-apart sandwiching portions 52 toward the base portion 54 and enters the reinforcing space R2. The flange portion 78 of the reinforcing member 76 is placed on the base end portion 52A. Then, the header 12 is pushed into the base 54 side. Then, the front end portion 52B of the sandwiching portion 52 rotates in the approaching direction, the front end portions 52B of the pair of sandwiching portions 52 approach each other, and the engagement piece 70 of the front end support portion 53 engages with the engagement hole 72. The header 12 is sandwiched between the sandwiching portions 52, and the sandwiching portions 52 are closed. As a result, the header 12 is fixed in a state of being separated from the mounting surface 48.

  In this way, by sandwiching the flange portion 78 between the sandwiching portion 52 and the header 12 and fixing the reinforcing member 76 together with the header 12, the header 12 is prevented from being deformed by an external load and is separated from the mounting surface 48. Damage to the fixed header 12 can be suppressed.

  Further, since the reinforcing member 76 can be disposed on the mounting surface 48 side of the header 12 or on the side opposite to the mounting surface 48, the reinforcing member 76 can be disposed on an appropriate side according to the fixing manner of the header 12. 76 can be arranged. For example, when the header fixture 11 is fixed to the ceiling, the header 12 can be protected by arranging a reinforcing member 76 on the opposite side of the header 12 from the ceiling. The reinforcing member 76 may be disposed on both the attachment surface 48 side and the opposite side of the attachment surface 48 of the header 12.

  Further, by fixing the header 12 away from the mounting surface 48, the workability at the time of pipe connection in the subsequent process can be improved.
