  The air conditioner 60 in the present embodiment functions as a circulating means for circulating the air exchanged with the air flow path 40 (shown in FIG. 2) into the chamber 1 (shown in FIG. 1).

[Attachment method of ceiling surface forming panel]
Next, a method for mounting the ceiling surface forming panel according to the embodiment of the present invention will be described with reference to FIGS. 3 and 10A to 10C. FIGS. 10A to 10C show a procedure for attaching the ceiling surface forming panel.

  The method of attaching the ceiling surface forming panel shown in the present embodiment includes “the operation of holding the ceiling surface forming panel (first step)”, “the operation of raising the ceiling surface forming panel (second step)”, Since each step of “horizontal movement operation of the ceiling surface forming panel (third step)” and “lowering operation of the ceiling surface forming panel (fourth step)” is sequentially performed, these steps will be sequentially described. To do.

  Moreover, in this Embodiment, the method to attach the heat-medium type panel 20 (1st panel) with respect to the 1st horizontal bar 420 and the 2nd horizontal bar 421 is demonstrated. It is assumed that the heat medium panel 20 (second panel) adjacent to the first panel is attached to the second horizontal rail 42B and the third horizontal rail (not shown).

"First step"
As shown in FIG. 10 (a), an operator (not shown) can connect the heat medium panel 20 (first panel) connected in advance to the first horizontal rail 420 and the auxiliary rail 27 by wires 26, 28, and the like. ) Is kept level. In this case, the heat medium type panel 20 (first panel) is disposed at a position where the back surface of the panel body 200 faces the free ends (arm portions 35b, 37b) of the springs 35, 37 for attaching the panel. .

  Since the heat medium type panel 20 (first panel) is connected to the first horizontal rail 420 and the auxiliary rail 27 by the wires 26, 28, etc., the worker is the heat medium type in the “first step”. Even if the panel 20 (first panel) is released, the heat medium panel 20 (first panel) does not fall on the floor.

"Second step"
Operator moves the heat medium type panel 20 (first panel) upwards (arrow _{v 1} direction FIG. 10 (a)), the arms of the spring 35 and 37 for panel mounting the back surface of the panel body 200 Press against 35b, 37b.

Next, the operator, as shown in FIG. 10 (b), the spring force against and arrow v ₁ direction to the heat medium type panel 20 of the spring 35 and 37 for panel mounting (first panel) further It is raised and arranged on the side of the first horizontal rail 420 and the second horizontal rail 421. In this case, in the heat medium type panel 20 (first panel), the lower end surface of the first hook 20b is higher than the upper end surface of the first hook engaging portion 420a, and the lower end surface of the second hook 20c. Are arranged so as to be positioned above the upper end face of the second hook engaging portion 421a.

"Third step"
As shown in FIG. 10C, the operator maintains the pressing state against the panel mounting springs 35 and 37 by the heat medium panel 20 in the “second step”, while the heat medium panel 20 ( The first horizontal beam 420 and the second horizontal beam 421 are moved from the position of the “second step” (the position shown in FIG. 10B) by moving the first panel) in the horizontal direction (arrow h direction). Place it at a position close to In this case, in the heat medium type panel 20 (first panel), the first hook 20b is located above the locking position by the first hook locking portion 420a, and the second hook 20c is related to the second hook. It arrange | positions so that it may each be located above the latching position by the stop part 421a.

"Fourth step"
The operator, as shown in FIG. 3, the heat medium type panel 20 (first panel) is moved downward (arrow v ₂ direction) while receiving the pressing force by the spring force of the spring 35 and 37 for panel mounting The first hook 20b of the heat medium type panel 20 (first panel) is connected to the first hook engaging portion 420a and the first hook 20b of the heat medium type panel 20 (second panel). The second hook 20c is locked to the second hook locking portion 421a. In this case, the locking of the first hook 20b to the first hook locking portion 420a and the locking of the second hook 20c to the second hook locking portion 421a are performed by the panel mounting spring 35, This is performed while the pressing state against the heat medium panel 20 by the spring force of 37 is maintained. Accordingly, the first hook 20b of the heat medium type panel 20 (first panel) is the first hook engaging part 420a, and the second hook 20c is the second hook engaging part 421a. When the panels 20 (second panels) are respectively locked through the first hooks 20b, the heat medium panel 20 is attached to the first horizontal rail 420 and the second horizontal rail 421.

  In this way, the heat medium type panel 20 (first panel) can be attached to the horizontal rail 42. Other heat medium panels 20 can be attached to the cross rail 42 by the same attachment method as the above attachment method.

  On the other hand, for the pneumatic panel 30, the chamber 31 is previously attached to the first horizontal rail 420 and the auxiliary rail 27, and then the panel body 300 is attached.

  The panel main body 300 of the pneumatic panel 30 is placed in a horizontal direction by a mounting method substantially the same as the mounting method of the heat medium panel 20, that is, through the steps substantially the same as the “first step” to “fourth step” described above. It is attached to the crosspiece 42.

  Accordingly, the chamber 31 is raised together with the panel body 300 in the second step, only the panel body 300 is moved in the horizontal direction in the third step, and the chamber 31 is lowered together with the panel body 300 in the fourth step. In the second step, the chamber 31 rises together with the panel body 300, but the spring 38 for holding the chamber does not become an obstacle to the rise.

  The holding of the chamber 31 with respect to the first horizontal rail 420 and the auxiliary rail 27 is performed through the steps shown in FIGS. 11 (a) and 11 (b). FIG. 11A shows a state in which the chamber holding spring 38 is elastically deformed, and FIG. 11B shows a state in which the chamber holding spring 38 is elastically restored.

[Effect of the embodiment]
According to the embodiment described above, the following effects can be obtained.

(1) The number of steps can be reduced when the heat medium panel 20 and the pneumatic panel 30 are attached, and the attachment work of the heat medium panel 20 and the pneumatic panel 30 can be easily performed.

(2) The locking force can be increased by the panel mounting springs 35 and 37, and the possibility that the heat medium panel 20 and the pneumatic panel 30 are detached from the crosspiece member 7 due to a relatively large shake such as an earthquake is eliminated. Can do.

(3) The heat medium panel 20 and the pneumatic panel 30 can be held substantially horizontally by the four wires 26 and 28 in the chamber 1, and the heat medium panel 20 and the pneumatic panel 30 in the substantially horizontal state.

In this case, when the holding state of the heat medium panel 20 and the pneumatic panel 30 by the two wires 28 is released and the heat medium panel 20 and the pneumatic panel 30 are held only by the two wires 26, the heat medium type Since the panel 20 and the pneumatic panel 30 can be maintained from a substantially horizontal state to a substantially vertical state, maintenance / inspection of the heat medium panel 20 and the back side of the pneumatic panel 30 and replacement of the pipe 21 and the chamber 31 are further performed. This can be done effectively, and simplification of maintenance / inspection work and replacement work can be achieved.

(4) Since the pipe 21 can be interposed between the light shielding sheet 25 on the base portion 200a of the panel main body 200 and the lower end surface of the first hook engaging portion 420a, on the back surface of the base portion 200a in the panel main body 200 The pipe 21 can be arranged over a wide area. Thereby, since it is not necessary to set the outer diameter d of the pipe 21 and the height of the panel main body 200 to the large dimension unlike the past, it can respond to thickness reduction of the suspension type heat-medium type panel 20.
