Next, the bolt 20a and the nut 20b are attached to the first installation member 14, the head portion 20f of the bolt 20a is inserted into the rail portion 24 of the fixing member 12, and is slid to a predetermined position, thereby tightening the nut 20b. The first installation member 14 is fixed.

  On the other hand, with respect to the second installation member 16, a jig 50 is attached so as to close the recess 38 in the suspension portion 28. The jig 50 holds the bolt 20a so that the head 20f of the bolt 20a is maintained in a state of protruding from the suspension portion main body 34 of the second installation member 16. Specifically, the pressing portion 52 of the jig 50 presses the flange portion 20g of the nut 20b, whereby the head portion 20f of the bolt 20a is held in a state of being separated from the side wall 34a of the suspension portion main body 34 by a predetermined distance. This predetermined distance is set to be slightly longer than the thickness of the presser portions 24c and 24d of the rail portion 24.

  The jig 50 may be mounted on the suspension portion 28 of the second installation member 16 at the installation site, or the second installation member 16 to which the jig 50 is previously mounted may be carried into the installation site. Good.

  Further, the jig 50 may be attached from the upper end side of the suspension 28 or from the lower end side. However, in order to mount the jig 50 from the lower end side, the jig 50 is mounted before the suspension part 28, the bracket 32, and the installation part 30 are fastened, and then the installation part 30 is connected. In this case, since the jig 50 cannot be removed after the outdoor unit 21 is installed, the jig 50 is destroyed and removed. Further, when the jig 50 is mounted from the upper end side, in order to mount the jig 50 in the direction of FIG. 7, the jig 50 may be mounted before the bolt 20a is inserted into the insertion hole 34c. It is also possible to mount the jig 50 in the direction opposite to that in FIG.

  Subsequently, the head portion 20f of the bolt 20a is inserted inside the rail portion 24 of the fixing member 12, and is slid to a predetermined position. Thereby, the fixing member 12 and the suspension part 28 (second installation member 16) are connected to each other in a state where they can be rotated by the connector 20 (connection step). At this time, the head portion 20 f of the bolt 20 a is inserted into the rail portion 24 while being maintained in a state of protruding from the suspension portion 28. That is, when the upper pressing portion 24c and the lower pressing portion 24d of the rail portion 24 enter the gap between the head portion 20f of the bolt 20a and the side wall 34a of the suspension portion main body 34, the fixing member 12 and the second installation member 16 are connected. Since the jig 50 is attached to the suspension portion 28 so as to cover the concave portion 38, the rail portion 24 does not fit into the concave portion 38 even when the second installation member 16 slides. For this reason, when the 2nd installation member 16 is rotated later, it can rotate smoothly. In addition, you may make it attach the fixing member 12 to a fixing body in the state which connected the suspension part 28 of the 1st installation member 14 and the 2nd installation member 16 to the fixing member 12. FIG.

  Next, as shown in FIG. 7, the second installation member 16 on which the jig 50 is mounted is rotated in a direction away from the first installation member 14, and the outdoor unit 21 is placed on the first installation member 14 (first 1 installation step). The placement work of the outdoor unit 21 holds the second installation member 16 in a rotated state, and lowers the outdoor unit 21 through the space between the second installation member 16 and the first installation member 14 in this state. The first mounting member 14 is mounted on the first installation member 14.

  At the time of this rotation, since the concave portion 38 is covered with the jig 50 in the holding portion 28 of the second installation member 16, the rail portion 24 does not fit into the concave portion 38 of the holding portion 28, so The installation member 16 can be smoothly rotated. For this reason, since it is not necessary for the operator to hold the second installation member 16 so that the rail portion 24 does not enter the concave portion 38, an operator who intends to install the outdoor installation 21 on the first installation member 14 is not required. This eliminates the need to pay attention to the second installation member 16.

  Further, when the second installation member 16 is rotated, the connector 20 rotates together with the second installation member 16 in a state of being fixed to the second installation member 16. That is, since the shaft portion 20e of the bolt 20a is engaged with the insertion hole 34c, the bolt 20a and the nut 20b rotate together with the second installation member 16. Therefore, the head 20 f of the bolt 20 a rotates within the rail portion 24.

  Further, when the second installation member 16 is rotated, the fixing member 12 and the second installation member 16 are connected to each other by the connector 20. That is, the bolt 20 a has a length that allows the second installation member 16 and the fixing member 12 to be connected in a state where the rail portion 24 is not fitted in the recess 38. The head 20 f of the bolt 20 a has a dimension that can be rotated inside the rail portion 24, and the shaft 20 e of the bolt 20 a has a dimension that cannot rotate with respect to the second installation member 16. It will be.

  Next, the recess 38 is exposed (exposure step), and the second installation member 16 is rotated in a direction approaching the first installation member 14 (return step). In order to expose the recess 38, the jig 50 may be slid and removed from the upper end of the suspension part 28, or the jig 50 may be slid (or not slid) and destroyed. . Note that either the exposure step or the return step may be first. That is, the second installation member 16 may be rotated after the recess 38 is exposed, or the recess 38 may be exposed after the second installation member 16 is returned to the original position. May be.

  Next, the rail portion 24 is fitted into the recess 38, and the outdoor unit 21 is placed on the second installation member 16 (second placement step). Then, by tightening the nut 20 b, the suspension portion 28 is fixed to the fixing member 12, and the outdoor unit 21 is fixed to the first installation member 14 and the second installation member 16. Thereby, the installation of the outdoor unit 21 is completed.

  As described above, in the present embodiment, when the fixing member 12 and the second installation member 16 are connected to each other by the connector 20, the second installation member 16 can be rotated with respect to the fixing member 12. At this time, since the concave portion 38 formed in the suspension portion 28 is covered with the jig 50, even if the second installation member 16 is rotated with respect to the fixing member 12, the rail portion 24 of the fixing member 12 is recessed. 38 is not caught. For this reason, since it is not necessary to hold | maintain the 2nd installation member 16 so that the rail part 24 may not fit in the recessed part 38, the burden on the operator at the time of installing the outdoor unit 21 on the 1st installation member 14 is reduced. can do. In addition, it is possible to prevent the fixing member 12 from coming into contact with the recess 38 and being damaged. Then, the recess 38 is exposed and the second installation member 16 is rotated until it reaches a position below the outdoor unit 21 placed on the first installation member 14, and is fixed to the recess 38 of the second installation member 16. If the rail part 24 of the member 12 is fitted, the second installation member 16 can be held in a predetermined posture. In addition, since the rotation operation of the 2nd installation member 16 at this time becomes operation in the state in which the outdoor unit 21 was installed in the 1st installation member 14, the state which the work burden holding the outdoor unit 21 was reduced This is a turning operation. Therefore, even if the second installation member 16 is rotated with the concave portion 38 exposed, this operation is not troublesome.

  In addition, in this embodiment, the head 20f of the bolt 20a attached to the second installation member 16 can be inserted into the rail portion 24 of the fixing member 12, and the connector 20 can be moved along the rail portion 24. Therefore, the connection location of the 2nd installation member 16 and the fixing member 12 can be set to arbitrary positions. The second installation member 16 can be rotated with respect to the fixed member 12 at this set position. For this reason, even if it is the structure where the rail part 24 is provided so that it may protrude with respect to the member main body 22 of the fixing member 12, the 2nd installation member 16 can be rotated without being caught in the recessed part 38. FIG.

  In the present embodiment, the flange 50g of the nut 20b is pressed by the jig 50, so that the bolt 20a nut 20b can be stably held against the second installation member 16, and in this state, the first 2 The installation member 16 can be rotated.

  Moreover, in this embodiment, since the jig 50 is removed last, the jig 50 is not left in the 2nd installation member 16, but the installation stand 10 can be cleared.

  Further, in the jig 50 of the present embodiment, the jig 50 can be externally fitted to the second installation member 16 in which the concave portion 38 is formed, and the concave portion 38 can be blocked by the jig 50 by sliding along the member 16. . And when fitting the rail part 24 of the fixing member 12 in the recessed part 38 of the 2nd installation member 16, the recessed part 38 can be exposed by shifting the jig 50 etc. FIG.

  Moreover, in the jig 50 of this embodiment, since the head part 20f of the volt | bolt 20a can be hold | maintained in the state protruded from the suspension part 28 in which the recessed part 38 was formed with the holding | suppressing part 52, rotation of the 2nd installation member 16 is possible. Sometimes the operator does not need to hold the connector 20. Therefore, the operation | work which connects the 2nd installation member 16 and the fixing member 12 can be made easy.

  Moreover, in the installation stand 10 of this embodiment, when the 2nd installation member 16 rotates with respect to the fixing member 12, the axial part 20e of the volt | bolt 20a currently engaged with the insertion hole 34c of the said 2nd installation member 16 is set. It rotates together with the second installation member 16. On the other hand, when the second installation member 16 is fixed to the fixing member 12, when the nut 20b is tightened against the male screw portion 20c, the shaft portion 20e of the bolt 20a is inserted into the insertion hole 34c of the second installation member 16. Since they are engaged, the female screw portion 20d can be screwed together without preventing the male screw portion 20c from rotating.

  Note that the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made without departing from the spirit of the present invention. For example, it is good also as a structure in which the recessed part 38 is formed in the suspension part 28 (suspending part main body 34) so that it may be depressed from the side surface, without the suspension part 28 having the protrusion part 36. That is, the side wall 34a itself in which the insertion hole 34c opens may be recessed in a rectangular shape in the hanging portion 28.

  Moreover, it is good also as a structure where the rail part 24 of the fixing member 12 does not protrude. In this case, the fixing member 12 itself is fitted into the recess 38 of the second installation member 16.

  The fixing member 12 may not have the rail portion 24. In this case, the fixing member 12 is formed with a bolt insertion hole 34 c at the connection position of the first installation member 14 and the second installation member 16, and the bolt insertion hole 34 c and the installation members 14, 16 are formed in the fixing member 12. The bolt 20a is inserted through the formed insertion hole 34c, and the installation member can rotate with respect to the fixing member 12. In this configuration, the connecting position of the installation member cannot be arbitrarily adjusted, but by providing a plurality of bolt insertion holes 34c, the connecting position can be adjusted step by step.

  Further, the recessed portion 38 may be provided in the fixing member 12 instead of the recessed portion 38 provided in the second installation member 16. In this recess 38, the second installation member 16 itself is fitted.

  In addition, the bolt 20a of the connector 20 has a polygonal shaft portion 20e and a head 20f having a circular cross section, but is not limited thereto. For example, the head 20f may be polygonal and the shaft 20e may be circular. In this case, the insertion hole 34c of the suspension part main body 34 is a circular hole. Moreover, as the connection tool 20, it is not restricted to a bolt nut.
