Further, the worker fixes the side pole 71 at one end in the moving direction of the curtain 51. For example, the outer edge of the first sheet 62a is folded back, the side pole 71 is sandwiched between the folded first sheet 62a, and the folded first sheet 62a is welded or sewn to fix the side pole 71 to the first sheet 62a. Next, the worker attaches the retaining member 53 to the lower end of the pole 61 arranged in the first rail 41. Further, the worker connects the pole 61 to the runner 52 by fixing the hanging member 52c to the upper end of the pole 61. Further, the worker arranges the hanging metal fitting 52b on the eyelet metal fitting 62c of the seat 62 and connects the eyelet metal fitting 62c to the runner 52. As a result, the curtain member 46 is assembled.

  Next, the worker installs the curtain 51 between the first rail 41 and the second rail 45 (step ST6). As a specific example, the worker arranges the runner 52 connected to the pole 61 and the seat 62 on the second rail 45. As a result, each pole 61 and the seat 62 are suspended on the second rail 45. Next, the worker inserts the lower end of the pole 61 into the first rail 41. At this time, the worker accommodates the lower end of the pole 61 into the first rail 41 by inserting the pole 61 from the cutout portion 41f provided in the first rail 41. As a result, the curtain member 46 is installed between the first rail 41 and the second rail 45. The worker performs the above-mentioned process for all the curtain members 46 to be installed, and installs all the curtain members 46 between the first rail 41 and the second rail 45.

  Next, the worker installs the storage walls 47 on both sides in the width direction of the frontage 15 (step ST7). As a specific example, an operator fixes a member having a top plate portion 47b fixed to the upper end of the wall portion 47a in advance to the wall 12. Thereby, the operator can store the curtain 51 at the widthwise end of the frontage 15. The storage wall 47 may be installed before the curtain member 46 is installed between the first rail 41 and the second rail 45. Through the above process, the curtain structure 17 is installed in the frontage 15 of the maintenance shop 1.

  In the garage 1 having the frontage 15, the groove 16, and the curtain structure 17 configured as described above, the frontage 15 can be opened and closed by the curtain 51, so that the space inside the chamber 14 and the outside can be easily separated. be able to.

  By covering the frontage 15 with the curtain 51, the flow of air inside and outside the chamber 14 can be reduced. Therefore, when the air conditioning equipment is used in the room 14 in the summer or winter, the temperature in the room 14 is compared with that in the state in which the frontage is opened, and the air flow inside and outside the room 14 can be prevented as much as possible. Further, since the curtain 51 is slidable on the first rail 41 and the second rail 45, opening and closing the frontage 15 is easy.

  Therefore, for example, even when the vehicle passes through the frontage 15 while using the cooling and heating equipment, the time required for opening and closing the frontage 15 may be as short as possible. Further, the frontage 15 can be partially opened depending on the position of the curtain 51. As a result, according to the maintenance factory 1 including the curtain structure 17, the environment of the room 14 can be maintained.

  In addition, since the flow of air inside and outside the chamber 14 can be prevented as much as possible, when the vehicle is ground in the chamber 14, it is possible to prevent dust generated by the polishing work from scattering outside the chamber 14. it can. Similarly, by covering the frontage 15 with the curtain 51 in rainy weather, it is possible to prevent rainwater from entering the chamber 14.

  Further, by providing the roof 13 with a heat insulating property or heat insulating property such as providing a heat insulating sheet on the roof 13, the temperature change in the room 14 is suppressed by the heat insulating property and heat insulating property of the roof 13 and the effect of the curtain structure 17. it can.

  Further, since the curtain structure 17 has a configuration in which the frontage 15 is partitioned by the curtain 51, it is possible to suppress sound transmission from the inside of the chamber 14 to the outside through the frontage 15 by the curtain 51. That is, the curtain structure 17 can reduce the noise leaked to the outside during the sheet metal work or the polishing work in the chamber 14.

  Further, the curtain structure 17 of the present invention includes the lid 43 and the stopper 81. Therefore, the worker can regulate the movement of the curtain 51 moving along the width direction of the frontage 15 at any position along the longitudinal direction of the first rail 41. Specifically, the operator inserts the bar 81b of the stopper 81 into the opening 43a of the lid 43 at a desired stop position. As a result, the bar 81b and the inner surface of the opening 43a come into contact with each other, whereby the operator can regulate the movement of the curtain 51.

  In this way, the operator can adjust the opening amount of the frontage 15. Therefore, the opening amount of the frontage 15 can be adjusted according to the usage situation.

  In addition, the lower end of the pole 61 is provided with a retaining member 53 that restricts the lower end of the pole 61 from moving above the first slit 41e. Therefore, even if the curtain 51 flies by the wind and the pole 61 moves in the direction of coming out of the first rail 41, the retaining member 53 interferes with the upper wall portion 41c of the first rail 41, and the pole 61 makes a first slit. It can be prevented from coming off from 41e. Therefore, the curtain structure 17 can be safely used even in a strong wind, and can prevent wind, dust, and the like from entering the chamber 14.

  Further, as the lid 43 of the present invention, a processed so-called grating lid can be used. That is, it is possible to use the grating lid that has been previously arranged according to the groove 16 of the maintenance shop 1. Therefore, the operator does not need to manufacture the lid 43 again, and the equipment cost can be suppressed.

  The sheet 62 of the curtain 51 is made of a translucent resin material. Therefore, even when the frontage 15 is closed by the curtain 51, external light is not blocked. Therefore, since the sunlight is not blocked by the curtain 51, the frontage 15 can be closed in a bright situation in the room 14. That is, when the frontage 15 is closed by the curtain 51 in the daytime or the like, it is possible to work using natural light without turning on the electric light. This is because even when the curtain 51 is closed, sufficient brightness can be maintained as in the case where the frontage 15 is opened, and therefore, for example, even in polishing work in which contrast between light and shadow is important. Good workability can be maintained.

  The curtain structure 17 is provided inside the roof eaves 13 a and outside the frontage 15. Therefore, the eaves 13a and the curtain 51 can prevent rain from entering.

  In addition, the plurality of intermediate poles 72 are provided on the surface of the seat 62 on the frontage 15 side. That is, since the second sheet 62b is arranged inside the chamber 14 and the first sheet 62a is arranged outside, the adhesive portion of the first sheet 62a and the second sheet 62b is located on the frontage 15 side.

  Therefore, when the intermediate pole 72 is arranged on the sheet 62, rainwater comes into contact with the adhesive, the adhesive strength of the first sheet 62a and the second sheet 62b deteriorates, and the first sheet 62a and the second sheet 62b peel off. Can be prevented.

  Similarly, when wind blows from the outside of the chamber 14 toward the inside of the chamber 14, the sheet receiving the wind is the main surface opposite to the main surface of the first sheet 62a on which the second sheet 62b is provided. Therefore, when the pressing force is applied to the first sheet 62a by the wind, the first sheet 62a pushes the pole 61. As a result, due to the wind blown during use, a pressing force is applied to the second sheet 62b in the same direction as the first sheet 62a, so that the second sheet 62b is bonded to the first sheet 62a and the second sheet 62b. No stress is applied in the direction of peeling from the first sheet 62a. Therefore, it is possible to prevent the first sheet 62a and the second sheet 62b from being peeled off by use.

  Further, the curtain 51 is provided on the outdoor side of the shutter 18. Therefore, it is possible to secure a larger indoor space than when the shutter 18 is closed and work, and it is possible to suppress the operator from feeling a sense of pressure even when the curtain 51 is closed.

  Further, since the curtain structure 17 has a configuration in which the bottom portion 41a of the first rail 41 has a plurality of holes 41d, even if rainwater, drainage, or the like enters the first rail 41, the groove portion is formed through the holes 41d. It can be discharged to 21. Therefore, it is possible to prevent water from accumulating in the first rail 41.

  Further, in the construction of the curtain structure 17, the curtain structure 17 can be installed by arranging the first rail 41 in the groove 16 provided in the front of the frontage 15 of the maintenance factory 1. For this reason, since the curtain structure 17 can be provided without newly providing a new groove, a large amount of work is not required from the conventional equipment. As a result, the curtain structure 17 can reduce the installation cost.

  The present invention is not limited to the above embodiment. For example, in the above-described example, the curtain 51 has a double-open structure, but the invention is not limited to this. For example, a so-called one-sided structure may be used in which the frontage 15 is opened and closed by one curtain 51. Further, although the nut is used as the retaining member 53, the present invention is not limited to this, and another member may be used as long as the pole 61 does not come out from the first slit 41e upward.

  Further, in the above-described example, the lid 43 has the grating lid that is disposed between the first receiving portion 22A and the second receiving portion 22B that are generally in circulation, and the width between the holding member 42 and the second receiving portion 22B. Although the structure of the grating lid additionally processed according to the above is explained, the invention is not limited to this. For example, the lid 43 having a width between the holding member 42 and the second receiving portion 22B may be manufactured in advance.

  Further, in the above-mentioned example, the vehicle maintenance factory 1 is used as the building, but the structure is not limited to this, and may be a warehouse, a commercial refrigerated warehouse, a factory, or a restaurant with a wide frontage. You can use it.
