FIGS. 4A and 4B are front views showing a mounting structure of the rail body 7 for mounting the heat shield sheet by the seat fixing tool 30. FIG. FIG. 5 is a front view showing an attached state of the heat shield sheet 5.

  Both ends of the heat shield sheet 5 are fixed to the rail body 7. The rail body 7 is formed of a concave groove body having side wall portions 7b, 7b inclined in the direction of narrowing the opening portion 7a, and the length dimension thereof is substantially the same as the length of the end portion in the width direction of the heat shield sheet 5. It is said. The heat shield sheet 5 is attached to the groove portion 7 c of the rail body 7, and is fixed by pressing the heat shield sheet 5 against the inner surface of the groove portion 7 c of the rail body 7 with the pressing member 8. The fixing structure is not limited to this.

  The sheet fixture 30 has a clamping structure in which the rail body 7 to which the end portion of the heat shield sheet 5 is fixed is clamped and fixed by screwing the tightening bolt 35 and the nut 36.

  Specifically, the sheet fixture 30 is formed into a U-shape having two pieces of leg portions 32 and 32 that extend from both ends of the base plate portion 31 and slightly open on the open end sides. As shown in FIG. 3, bolt insertion holes 32 a and 32 a through which the tightening bolts 35 are inserted are formed in the respective leg portions 32 and 32. On the open end side of the leg portions 32, 32, sandwiching portions 33, 33 for sandwiching and fixing the rail body 7 are formed. The sandwiching portions 33 and 33 are shaped so that the rail body 7 can be fitted, and the inclined side wall portions 7b and 7b of the rail body 7 are pressed to both ends of the leg portions 32 and 32 in the width direction. L-shaped pressing pieces 33a and 33a are formed, which are connected by reinforcing pieces 33b and 33b on the opening 34 side of the leg portions 32 and 32, respectively.

  That is, when this U bolt 21A is used, the rod-like body 20 is inserted with the longer screw in a state where it is inserted between the fixed plate portion 12 and the base portion 21b of the U bolt 21A attached from below the fixed plate portion 12. By fixing the sheet fixing tool 30 using the foot 21a as the tightening bolt 35, both the sheet fixing tool 30 and the rod-shaped body 20 can be attached to the support member 10 with one fixing member.

  Further, when such a U-bolt 21A is used, a fixing member for fixing the rod-like body 20 and the sheet fixture 30 can be made common, the number of members can be reduced, and the mounting structure can be simplified. Further, if the nut 36 on the upper side of the seat fixture 30 is tightened, both the rod-shaped body 20 and the seat fixture 30 are fixed at the same time, so it is not necessary to fasten the nut to the shorter threaded foot portion 21a. Furthermore, the number of parts can be reduced.

  As described above, the rod-shaped body 20 and the sheet fixing tool 30 can be attached to a position separated from an appropriate position of the support member 10, or the same position using the U bolt 21A of FIG. 6 (c). Can be attached to.

  Further, since a plurality of bolt insertion holes 13 are formed in the fixing plate portion 12 of the support member 10, an appropriate one of them may be selected and the rod-shaped body 20 and the sheet fixing tool 30 may be attached. If the bolt insertion holes 13 and 13 are long holes as shown in FIG. 1B, the attachment of the rod-like body 20 and the sheet fixture 30 can be easily adjusted and the attachment work can be performed efficiently.

  Further, when the rod-like body 20 and the sheet fixture 30 are attached in combination as shown in FIG. 6B using the U bolt 21A of FIG. 6C, two sets of combinations are attached to one outdoor unit 1. You may use the supporting member 10 which provided the bolt insertion hole 13 2 each at the both ends of the fixed board part 12, etc. so that it might be attached. Since the bolt insertion holes 13 may be small, the bolt insertion holes 13 may be opened in accordance with the dimensions of the heat shield sheet 5 and the like on site.

  In the above, the structure in which the heat shield sheet 5 and the rod-shaped body 20 are bridged between the same types of outdoor units 1 and 1 is shown. Good. Further, the rod-like body 20 may be attached to the upper surface side of the fixing plate portion 12 of the support member 10 and the sheet fixing tool 30 may be attached to the lower surface side of the fixing plate portion 12.
