For example, pin 35,
45 may be fitted along the vertical holes 34 and 44 so as to be movable up and down and fixed with a fixing bolt.

Next, the structure for attaching the unit frame 2 to the ridge 1 will be described. As shown in FIGS. 1, 2 and 3, left and right upper unit frame brackets 30 and 3 attached to the unit frame 2.
0, one pin 35 is fitted from above into the first vertical hole 13 of one upper cubic bracket 10 attached to the left and right cubicles 1, 1 and the other pin 35 is The fitting portion 3 is fitted into the second vertical hole 14 of the upright bracket 10 from above.
The lower surface of the unit frame 2 contacts the upper surface of the support portion 12 of the upper cubic bracket 10 via the washer 17 to connect the upper part of the unit frame 2 to the cubicle 1. One of the pins 45 is fitted into the first vertical hole 23 of one of the lower cubic brackets 20 attached to the right and left adjacent cubicles 1, 1 and the other pin 45
Fits into the second vertical hole 24 of the other upper cubic bracket 20 and connects the lower part of the unit frame 2 to the cubicle 1. There is a gap b between the lower surface of the mounting portion 42 of the lower unit frame bracket 40 and the upper surface of the support portion 22 of the lower cubic bracket 20 to absorb a mounting error in the height direction of the unit frame 2 and The displacement caused by the thermal expansion of the cubic 1 is absorbed. The back plate 7 is formed with first and second mounting bolt holes 7b and 7c at symmetrical positions with respect to the fixing screw hole 7a. The back plate 7 is mounted upside down with the back plate 7 upside down. The upper and lower cubic brackets 10 and 20 can be attached to predetermined positions.
The thickness of the washer 17 provided on the upper surface of the support portion 0 is the same as that of the gap b. Therefore, even if the upper and lower cubic brackets 10 and 20 have the same shape and the back plate 7 is mounted upside down, the gap is smaller. b with unit frame 1
Can be linked to Also, upper and lower cubic brackets 10,
20 and the upper and lower unit frame brackets 30 and 40 are vertically symmetrical and have the same thickness, so that good design can be achieved. Each of these brackets is located on the outdoor side of the cubic 1. As a result, the cover material becomes invisible from the indoor side, and the cover material is not required. The thickness of the support portion 12 of the upper cubic bracket 10 may be increased by the thickness of the washer 17 so that the washer 15 is not attached.

Next, a method of attaching the unit frame 2 to the cubicle 1 will be described. The cubicles 1 are mounted on the wall of the building at intervals in the left-right direction.

Upper and lower unit frame brackets 3 at the top and bottom of the left and right vertical frames 6, 6 in the unit frame 2
Fix 0,40 with bolts. The unit frame 2 is lifted by a crane or the like and transported upward, and is fitted from above into the first vertical hole 13 of the upper stanchion bracket 10 in which the pin 35 of the left upper unit frame bracket 30 is bolted to the left stanchion 1. At the same time, the right upper unit frame bracket 30
Of the unit frame 2 is connected to the second vertical hole 14 of the upper cubic bracket 10 bolted to the right cubicle 1 from above. The lower vertical bracket 20 attached to the left and right cubicles 1 is slid downward along the concave groove 3 so that the first vertical hole 23 of the lower cubicle bracket 20 mounted to the left cubicle 1 is moved to the lower left side. The lower portion of the unit frame 2 is fitted to the pin 45 of the unit frame bracket 40, and the second vertical hole 24 of the lower right side bracket 20 is fitted to the pin 45 of the right lower unit frame bracket 40 so that the lower portion of the unit frame 2 is mounted on the right side 1. Connect to The lower cubic bracket 20 is fixed to the cubic 1 with bolts 25.

Next, a second embodiment will be described with reference to FIGS. The cubic 1 is an H-shaped steel having an E-shaped cross section, and upper and lower cubic bracket support portions 50 and 60 are fixed to the outdoor surface 1a of the cubic 1 by welding or the like. The upper cubic bracket support 50 is a long L-shaped vertical plate 51.
Cross section T in which longitudinal ribs 52 are integrally provided at the widthwise intermediate portion of
It has a shape having a stopper portion 53 at the lower portion, and the lower cubic bracket support portion 60 has a cross section T in which a longitudinal rib 62 is integrally provided at a widthwise middle portion of a long L-shaped vertical plate 61.
