  However, in the frame-shaped mounting table disclosed in Patent Document 1, when the outdoor unit is installed in a plurality of stages in the height direction or when a roof is provided, the vertical vertical member is extended to the top. In order to assemble a base frame for the lower outdoor unit using the horizontal horizontal member and install the outdoor unit on the base frame, the vertical member is introduced into the frame to install the lower outdoor unit. There was a problem of becoming an obstacle.

  If the interval between the vertical members is widened to avoid this, the frame-shaped mounting base becomes large, which may cause a problem in layout.

  Then, an object of this invention is to obtain the frame-shaped installation base which can install an outdoor unit more easily by a more compact structure.

  Thus, after attaching the first-stage (lower) outdoor unit U, as shown in FIG. 7, the four vertical members 4 are fixed. At this time, at the corners of the pedestal frame, the vertical wall portions 5a and 6a of the flat plate-like coupling member 5 and the L-shaped coupling member 6 are erected opposite to each other at an interval at which the vertical member 4 is just inserted, The vertical member 4 can be inserted between these vertical wall portions 5a and 6a and guided to a predetermined coupling position.

  At this time, in the flat plate-shaped coupling member 5 and the L-shaped coupling member 6, the side wall portions 5 b and 6 b having a U-shaped cross section together with the vertical wall portions 5 a and 6 a are also lateral (in this embodiment, along the horizontal horizontal member 3. It functions as a guide portion that guides the vertical member 4 in the vertical direction while restricting movement in the direction).

  In the present embodiment, as described above, the upper edge 5d of the flat plate-shaped coupling member 5 and the upper edge 6d of the L-shaped coupling member 6 are shifted in the vertical direction. When the vertical member 4 is inserted into the gap with the coupling member 6, the vertical member 4 is only projected on one side of the flat coupling member 5 and the L-shaped coupling member 6 (L-shaped coupling member 6 in this embodiment). And can be introduced and guided smoothly into the gap.

  The upper L-shaped coupling member 6 is temporarily fixed to the horizontal vertical member 2, and the L-shaped coupling member is fixed to the horizontal vertical member 2 after the vertical member 4 is arranged at an intended position. Also good.

  Then, as shown in FIG. 8, the horizontal vertical member 2 and the horizontal horizontal member 3 are erected and fixed on the upper edge of the vertical member 4 in the same manner as the first (lower) pedestal frame. An upper pedestal frame is constructed, and a pair of horizontal support members 7 are installed between the pair of horizontal horizontal members 3, and the second (upper) outdoor unit U is mounted on the horizontal support member 7.

  Here, in the second stage pedestal frame, the joints of the plurality of vertical members 4, 4 are not formed, and one vertical member 4 penetrates up and down at the member coupling portion of the horizontal vertical member 2 and the horizontal horizontal member 3. is doing. That is, the flat plate-like coupling member 5 and the L-shaped coupling member 6 according to the present embodiment both have a case in which one vertical member 4 is penetrated at a member coupling portion of the pedestal frame and two vertical members 4. The vertical member 4 can be used as a reinforcing member at any height position between the upper and lower pedestal frames using the flat plate-like coupling member 5 and the L-shaped coupling member 6. A horizontal vertical member 2 or a horizontal horizontal member 3 can be installed between the four.

  The vertical member 4 is preferably suspended by a wire 18 for preventing the collapse.

It is not necessary to increase the interval, and a more compact configuration can be achieved.

  In this case, the vertical wall 4 a is formed by the vertical wall portion 5 a of the flat plate-shaped coupling member 5 and the vertical wall portion 6 a of the L-shaped coupling member 6. Depending on the position, it can be provided more easily and smoothly.

  Further, according to the present embodiment, since the flat coupling member 5 is formed in a substantially T shape, one or two vertical members 4 penetrate the member coupling portion in the vertical direction, and the flat coupling member 5. Therefore, when the horizontal transverse member 3 and the vertical member 4 are coupled in a substantially T shape, waste of the flat coupling member 5 can be reduced.

  Moreover, according to this embodiment, since the vertical member 4 can be guided to the up-down direction by the side wall parts 5b and 6b as a guide part, the vertical member 4 can be combined more easily in the said member connection location. it can.

  In addition, according to the present embodiment, the upper edges 5d and 6d or the lower edges 5d and 6d of the vertical wall portions 5a and 6a facing each other are shifted in the vertical direction, and the vertical wall portions 5a and 6a facing each other are shifted. By projecting either one of them upward or downward, the vertical member 4 can be more smoothly guided to a predetermined coupling position by the protruding vertical wall portion (6a in the present embodiment).

  Moreover, according to this embodiment, the horizontal edges 2d and 6d, or the lower edges 5d, 5d, 6d, or the lower edges 5d, 6a, 6a are opposed to each other by shifting the horizontal vertical member 2 and the horizontal horizontal member 3 in the vertical direction. It is possible to easily obtain a state in which 6d is shifted in the vertical direction.

  In addition, according to the present embodiment, a space having a substantially constant height can be secured in the horizontal direction under the pair of horizontal vertical members 2 and the horizontal support member 7, so that the piping for the outdoor unit U is arranged. It can be effectively used as a search space.

  Further, the horizontal vertical member and the horizontal horizontal member may be provided at the same height position, or the direction in which the horizontal vertical member and the horizontal horizontal member are shifted may be set in reverse.

  Further, in the above embodiment, the case where the outdoor units are stacked in two stages is illustrated, but the case where the roof is attached using a vertical member on the outdoor unit or when the roof is further stacked in multiple stages is completely different from the above embodiment. This can be handled in the same way.

  Moreover, it is good also as shapes other than having disclosed in the said embodiment, a flat coupling member, an L-shaped coupling member, a horizontal vertical member, a horizontal horizontal member, a vertical member, etc.
