<About overview>
In this embodiment, in order to protect the human body from the radiant heat emitted from the roof of the building, the sheet material is attached along the lower surface of the roof of the building. Prior to the description of the sheet material mounting structure and method, a general factory working environment will be briefly described with reference to FIG.

  Referring to FIG. 16, a general factory 100 does not have a ceiling below the roof 11. The “ceiling” is a member that vertically divides a space located below the roof 11, that is, the entire indoor space 9 surrounded by the roof 11, the floor 16, and the outer walls 12, 13,. In the factory 100, the plurality of beams 17 that support the roof 11 are exposed in the indoor space 9. The roof 11 is, for example, a folded plate roof.

  An air supply gallery 133 and an exhaust fan 134 are provided on the outer walls 12 and 13 facing each other to ventilate the indoor space 9 of the factory 100. The air supply louver 133 is disposed on the lower side of the outer walls 12 and 13 and naturally takes in the outside air and supplies it to the indoor space 9. The exhaust fan 134 is disposed above the outer walls 12 and 13 and discharges contaminants generated in the indoor space 9. The exhaust fan 134 is disposed, for example, with the vicinity of the lower end position of the beam 17 as the upper end. For example, two exhaust fans 134 are provided for each of the outer walls 12 and 13.

  In such a factory 100, when the roof 11 receives solar heat in summer, the temperature of the roof 11 exceeds 60 ° C. Even when a high solar reflectance paint is applied to the roof 11, the temperature of the roof 11 can only be expected to decrease by about 10 ° C. Even if the air temperature in the indoor space 9 is lowered to some extent by the exhaust fan 134 or the like, the temperature of the roof 11 is maintained at a high temperature and continues to emit strong radiant heat. Therefore, the temperature in the indoor space 9 becomes high due to the radiant heat from the roof 11. In addition, since various internal devices 93 exist in the factory 100, the temperature in the indoor space 9 rises due to internal heat generated by these devices 93. As a result, hot air stays in the indoor space 9 as indicated by the dashed-dotted ellipse in FIG. Furthermore, since the factory 100 has nothing to block the radiant heat, the sensible temperature of the operator is increased by about 2 ° C., for example, due to the radiant heat from the roof 11. Therefore, the indoor space 9 of the general factory 100 in the summer becomes a very harsh working environment.

  In the present embodiment, in order to improve such a working environment, the sheet material is arranged along the lower surface of the roof 11 in the manner of parasoling the human body in the factory. A heat exhaust structure of a building in which a sheet material is arranged will be described with reference to FIGS. 1 and 2. FIG. 1 shows a factory 1 as a building without a ceiling. In FIG. 1, the same reference numerals are given to the same or corresponding components as those of the general factory 100 shown in FIG.

  Like the general factory 100, the factory 1 includes a folded plate-like roof 11, opposed outer walls 12 and 13, and a plurality of beams 17 that support the roof 11. The plurality of beams 17 are arranged in an exposed state in the indoor space 9. The beam 17 is assumed to be an H shape corresponding to a so-called large beam, but may be a small beam orthogonal to the large beam. The plurality of beams 17 are arranged at intervals in the first direction (direction indicated by arrow A1), and each extend in a second direction (direction indicated by arrow A2) orthogonal to the first direction. ing. In FIG. 2, the arrangement positions of the beams 17 are indicated by a one-dot chain line DL1.

  In the present embodiment, using the exposed beams 17, a plurality of sheet portions 5A that partition the indoor space 9 in the vertical direction are arranged with a gap therebetween. Each sheet portion 5 </ b> A may be configured by a single sheet material 5, or may be configured by arranging a plurality of sheet materials 5 with overlapping.

  Each sheet material 5 is preferably a member that shields radiant heat from the roof 11 (heat shield material). More specifically, the radiant heat is higher than that of the sheet material 5 such as a material that reflects radiant heat. It is desirable to be formed of a material that suppresses transmission to a space located below. In that case, the emissivity of the surface of the sheet material 5 is desirably small. Specifically, for example, a metal material such as aluminum is assumed as the material of the sheet material 5. However, it is desirable that the sheet material 5 is flexible, thin, and lightweight. The thickness of the sheet material 5 is, for example, about 0.2 to 2.0 mm.

  In the following description, in the indoor space 9 of the factory 1, a small space (a space between the roof 11 and the sheet material 5) located above the sheet material 5 (the sheet portion 5A) is referred to as an “upper space 91”. . A large space below the sheet material 5 (a space between the sheet material 5 and the floor 16) is referred to as a “lower space 92”. The lower space 92 is a work space for workers.

  As shown in FIGS. 1 and 2, in the factory 1, for example, two exhaust fans 134 are provided on the upper space 91 side of one outer wall 13 in the same manner as the general factory 100. On the other hand, instead of the exhaust fan 134 of the general factory 100, for example, two air supply fans 137 are provided on the upper space 91 side of the other outer wall 12. The air supply gallery 133 is provided below the outer wall 12 where the air supply fan 137 is provided, but is not provided below the outer wall 13 where the exhaust fan 134 is provided.

  In the present embodiment, the two exhaust fans 134 are provided on the outer wall 13 at a position near the outer wall 14 and a position near the outer wall 15, respectively. The two air supply fans 137 are provided at positions facing these exhaust fans 134. As shown in FIG. 1, the air supply fan 137 and the exhaust fan 134 are located between the lower end position of the beam 17 and the sheet material 5. Note that at least one of the fans 137 and 134 may be disposed at the same height as the beam 17. In that case, the fans 137 and 134 may be provided on the inner side of the beam 17 positioned closest to the outer wall, and a duct extending from the fans 137 and 134 may penetrate the web of the beam 17 and the outer walls 12 and 13.

  It is desirable that the air supply fan 137 has high air straightness and a long reach distance. The air supply fan 137 takes in the outside air and blows the air into the upper space 91, thereby sending air to the exhaust fan 134 provided on the opposing outer wall 13. Thereby, the hot air staying in the upper space 91 flows vigorously on the plurality of sheet materials 5.

  Here, as shown in FIG. 2, a plurality of sheet portions 5A are arranged in both the first direction and the second direction. A gap 90a illustrated in FIG. 2 is a gap between adjacent sheet parts 5A in the second direction, and a gap 90b is a gap between adjacent sheet parts 5A in the first direction. These gaps 90a and 90b may be any distance that allows air in the lower space 92 to be taken into the upper space 91, and is, for example, 100 to 500 mm.

  As described above, in the present embodiment, since the gaps 90a and 90b exist between the adjacent sheet portions 5A, the air in the lower space 92 also moves upward from the gaps 90a and 90b as the air flows in the upper space 91. Attracted to space 91. Therefore, the exhaust fan 134 discharges hot air due to radiant heat staying in the upper space 91 and air (hot air) in the lower space 92 attracted from the gaps 90a and 90b.

  Thus, according to the factory 1 of the present embodiment, both exhaust heat of radiant heat and ventilation of the work space can be realized. Therefore, the temperature rise of the lower space 92 can be suppressed, and as a result, the working environment can be improved. Note that the sheet portion 5A only needs to be arranged with a gap between each other only in one of the first direction and the second direction. Further, the plurality of sheet portions 5 </ b> A may be arranged only on a part of the lower surface of the roof 11.

  In order to realize the exhaust heat heat radiation structure from the roof 11 as described above, it is necessary to attach the sheet material 5 at a high place. In the present embodiment, in order to perform this attachment work easily, the sheet material 5 is attached using a field edge as a ceiling base material.

  Below, the attachment structure and method of the sheet | seat material 5 using a field edge are demonstrated in detail.

<Embodiment 1>
With reference to FIG. 3 and FIG. 4, a seat mounting structure and method according to Embodiment 1 of the present invention will be described.

  In the present embodiment, as shown in FIGS. 3 and 4, the plurality of field edges 2 are suspended and connected to the beam 17 via the field edge receiver 70. The field edge receiver 70 extends, for example, in the same second direction as the beam 17 and is provided at an interval in the first direction. In this case, the field edge 2 extends in the first direction and is provided with a gap in the second direction. In FIG. 1, the field edge 2 is indicated by an imaginary line, and in FIG. 2, the arrangement position of each field edge 2 is indicated by a two-dot chain line DL <b> 2.

  The field edge receiver 70 has a U-shaped (U-shaped) cross section and is supported by a hanger 72 suspended by a suspension bolt 71 fixed to the flange of the beam 17. In FIG. 3, in order to show the shape of the field edge receiver 70 in an easily understandable manner, the portion of the hanger 72 that supports the opening side of the field edge receiver 70 is not shown.

  The field edge 2 is a general ceiling base material made of steel and has a substantially U-shaped cross section. Specifically, as shown in FIG. 4, the field edge 2 has a bottom portion 21 and a pair of side walls 22 extending upward from the bottom portion 21. The field edge 2 further includes a pair of bent portions 23 provided along the upper edge of the pair of side walls 22 and projecting inward and downward. The bent portion 23 is provided to be hooked to a pair of legs of a clip (not shown) hooked to the field edge 2 when the field edge 2 is connected to the field edge receiver 70. .

  Generally, at least one recess 24 is provided on the lower surface (bottom surface) of the bottom 21 of the field edge 2. The field edge 2 of the present embodiment is a field edge called a so-called double bar. When viewed from below, the bottom part 2 extends 2 in the longitudinal direction (first direction) of the field edge 2. Two recesses (grooves) 24 are provided. The concave portion 24 corresponds to the back side of the raised portion where a part of the plate-like bottom portion 21 is raised upward. That is, the cross-sectional shape of the recess 24 in the bottom 21 is C-shaped or U-shaped.

  In the present embodiment, the sheet material 5 has a length in the first direction. The length of the sheet material 5 in the longitudinal direction is, for example, about 5 to 10 m (meters). Further, in the present embodiment, for example, the sheet portion 5A is formed by arranging the two sheet members 5 in the width direction (second direction) without any gap (preferably with overlap). In this case, a plurality of field edges 2 are fixed so as to form a set of three. The three field edges 2 forming the set are arranged at a predetermined pitch L1 (for example, 1200 mm). The field edges 2 of the other groups are arranged at a predetermined pitch L2 (for example, 200 mm) in order to form the gap 90a between the sheet portions 5A.

  In this case, the width dimension of the sheet material 5 corresponds to the arrangement pitch L1 of the field edge 2 and is, for example, about 1200 to 1300 mm. Accordingly, both end portions in the width direction of the sheet material 5 are fixed to the bottom portions 21 of the adjacent field edges 2 by the screw members 61 which are examples of fixing members. The screw member 61 is, for example, a screw. The sheet material 5 is fixed by a screw member 61 at a predetermined pitch (for example, 300 mm). For example, an electric screwdriver called impact is used to fix the screw member 61.

  Of the three field edges 2 forming the pair, the field edge 2 positioned at the center is fixed so that the end portions in the width direction of the two sheet materials 5 overlap each other. Two screw members 61 may be inserted into the bottom portion 21 of the field edge 2 located in the center for fixing one sheet material 5 and fixing the other sheet material 5.

  The attachment work of the sheet material 5 is started after the field edge 2 is suspended and connected to the beam 17. The work of attaching the sheet material 5 is performed using an aerial work vehicle 8 as shown in FIG. The aerial work vehicle 8 includes a bucket 81 having a work floor and an elevating unit 82 for elevating the bucket 81 up and down. Since the aerial work vehicle 8 cannot move while the bucket 81 is raised, it is necessary to repeat the raising and lowering of the bucket 81 in order to attach the long sheet material 5. In such a case, not only the construction of the sheet material 5 takes time, but also the cooperative work between the high place and the floor surface height is required, so the sheet material 5 cannot be constructed easily. In addition, when one end side of the sheet material 5 is fixed to the field edge 2 and the other end side of the sheet material 5 is hung down to the height of the floor surface, it not only disturbs other work in the factory 1, The sheet material 5 may be dangerous because it is blown by the wind.

  Therefore, in this Embodiment, as shown in FIG. 3, the sheet | seat material 5 previously wound by roll shape is used. The sheet material 5 is wound in the longitudinal direction. Thereby, the bucket 81 can be raised and lowered in a state where the roll part 50 of the sheet material 5 is accommodated in the bucket 81.

  In the present embodiment, as shown in FIG. 3, fixing work of the sheet material 5 to the field edge 2 and holding of the roll unit 50 are performed by two workers, respectively. That is, one worker holds the roll portion 50 of the sheet material 5 close to the field edge 2 and applies a tensile force to the sheet material 5. In this state, the other worker pulls the sheet material 5 pulled out from the roll part 50 to the field edge 2 by the screw member 61. Thus, in this Embodiment, the attachment operation | work of the sheet | seat material 5 can be safely performed by two workers performing a cooperation operation | work. In this case, the aerial work vehicle 8 is used for each worker.

  As described above, in the present embodiment, the field edge 2 as the ceiling base material is used as the base frame of the sheet material 5. Therefore, it is not necessary to manufacture a special member for suspending the sheet material 5 on the beam 17. Further, since the sheet material 5 is fixed only by the screw member 61, the sheet material 5 can be easily attached.

  In addition, although the width direction edge part of the sheet | seat material 5 is being fixed with the screw member 61, respectively, in order to prevent the fall of the sheet | seat material 5 reliably, a sheet | seat attachment structure has fall prevention as shown in FIG. It is desirable to further include a member 62. An example of attachment of the fall prevention member 62 is shown in FIGS. FIG. 6 shows a cross section along the second direction of the seat mounting structure in a state where the fall prevention member 62 is mounted. FIG. 7 shows a cross section along the first direction of the seat mounting structure in a state where the fall prevention member 62 is mounted.

  The fall prevention member 62 extends in a direction perpendicular to the extending direction of the field edge 2 (second direction), and spans the three field edges 2 forming a set below the two sheet members 5. Fixed. The fall prevention member 62 has, for example, an L-shaped cross section, and includes a horizontal plate portion 621 extending in the horizontal direction and a vertical plate portion 622 extending downward from one end of the horizontal plate portion 621. The horizontal plate portion 621 is provided with a through hole 623 for each arrangement pitch L1 of the field edge 2.

  It is desirable that the fall prevention member 62 is disposed at a position different from the position fixed by the screw member 61 described above. The fall prevention member 62 is fixed to the field edge 2 by inserting another screw member (fixing member) 63 into the through hole 623 in a state where the sheet material 5 is sandwiched between the horizontal plate portion 621 and the three field edges 2. The Since the fall prevention member 62 is bridged over the three field edges 2, the sheet material 5 can also be prevented from loosening.

<Embodiment 2>
A seat mounting structure and method according to Embodiment 2 of the present invention will be described with reference to FIGS.

  Also in the present embodiment, a plurality of sheet materials 5 are attached using the field edge 2, but the sheet mounting structure according to the present embodiment is a temporary fixing tool for temporarily fixing the sheet material 5 to the field edge 2. 3 and 3A. Moreover, when attaching the sheet material 5, the roll holding member 4 for holding the roll part 50 of the roll-shaped sheet material 5 in a high place is used.

A sandwiching portion 32 for sandwiching the width direction end portion and a contact portion 33 contacting the one side wall 22 of the field edge 2 are included. A through hole 320 penetrating in the vertical direction is provided at the center of the sandwiching portion 32.

  On the upper surface of the sandwiching portion 32 of the temporary fixture 3, a convex portion 34 that fits into the concave portion 24 provided on the bottom surface of the field edge 2 is provided. Since the groove-shaped two recesses 24 extending in the first direction are provided on the bottom surface of the field edge 2, as shown in FIG. Two convex portions 34 extending to both end edges in the direction 1 are provided. The convex part 34 is equivalent to the upper side of the raised part where a part of the plate-like sandwiching part 32 rises upward. That is, the cross-sectional shape of the convex part 34 in the clamping part 32 is also C-shaped or U-shaped. Accordingly, a concave portion 34 a is formed on the lower surface of the sandwiching portion 32 at a position behind the convex portion 34.

  Referring to FIG. 10, temporary fixing tool 3 </ b> A has another clamping portion in addition to the configuration of temporary fixing tool 3 shown in FIG. 9. That is, when the sandwiching portion 32 is referred to as the first sandwiching portion 32, the temporary fixing tool 3 </ b> A is folded back from one end of the first sandwiching portion 32, and the second sandwiching portion 35 facing the first sandwiching portion 32 is further provided. Have. The second clamping part 35 is also provided with a through-hole 350 penetrating in the vertical direction at the same position as the through-hole 320 of the first clamping part 32.

  On the upper surface of the second clamping part 35, a convex part 36 that fits into the concave part 34 a located on the back side of the convex part 34 of the first clamping part 32 is provided. Since the groove-shaped two recesses 34a extending in the first direction are provided on the lower surface of the first sandwiching portion 32, the upper surface of the second sandwiching portion 35 has both end edges in the first direction. Two convex portions 36 extending to the top are provided. The convex portion 36 corresponds to the upper side of the raised portion where a part of the plate-like second sandwiching portion 35 rises upward. That is, the cross-sectional shape of the convex part 36 in the 2nd clamping part 35 is also C-shaped or U-shaped.

  The end portion of the second sandwiching portion 35 can be pulled down with respect to the first sandwiching portion 32, and the width direction of another sheet material 5 is between the lower surface of the first sandwiching portion 32 and the upper surface of the second sandwiching portion 35. The end can be sandwiched. In addition, the 2nd clamping part 35 returns to the state which adjoined or contacted the 1st clamping part 32 with the elastic force.

  Referring to FIG. 11, roll holding member 4 suspends and holds roll portion 50 of sheet material 5. For example, the roll holding member 4 is disposed at the center of the roll portion 50, and protrudes on both sides in the width direction of the roll portion 50, and a pair of string-like shapes in which the lower ends are connected to both ends of the core member 41. The material 42 and the rod-shaped material 43 with which the upper end of a pair of string-shaped material 42 was connected are included. The rod-shaped material 43 is disposed substantially in parallel with the core material 41.

  The attachment method (and attachment structure) of the sheet | seat 5 using the above temporary fixing tools 3 and 3A and the roll holding member 4 is demonstrated along the construction order shown to the flowchart of FIG.

  Referring to FIG. 12, first, a plurality of field edges 2 are suspended and connected to beam 17 in the same manner as in the first embodiment (step P1). That is, the operator connects the suspension bolt 71 to the beam 17 and attaches the edge receiver 70 to the hanger 72 fixed to the suspension bolt 71. When the plurality of field receivers 70 are attached, the plurality of field edges 2 are connected to the field receiver 70 so as to be orthogonal to the field receiver 70 by using a latch fitting called a clip.

  When the plurality of field edges 2 are suspended and connected to the beam 17, the operation shifts to the attachment work of the sheet material 5. In the present embodiment, the sheet material 5 can be attached by one worker.

  First, the worker supports the roll holding member 4 on the field edge 2 of the first span (process P2). Here, one span is a section divided by two adjacent field receivers 70. Specifically, as shown in FIG. 13, both end portions of the rod-shaped material 43 of the roll holding member 4 are bridged over two adjacent field edges 2.

  When the roll part 50 of the sheet material 5 is held in the vicinity of the field edge 2, the operator pulls out the sheet material 5 from the roll part 50 (process P3), and performs the fixing work of the sheet material 5 at a predetermined position. (Process P4).

  In the fixing operation, first, the widthwise ends of the drawn sheet material 5 are temporarily fixed to the two field edges 2 on which the roll holding member 4 is bridged by the temporary fixing tools 3 and 3A (process P41). . The temporary fixing of the sheet material 5 will be described with reference to FIG. The sheet material 5 is temporarily fixed to the field edge 2a located at one end and the field edge 2b located at the center among the three field edges 2 of FIG. Here, in the second direction that coincides with the width direction of the sheet material 5, the direction in which these field edges 2a and 2b face each other is referred to as the inside, and the opposite direction is referred to as the outside.

  In the temporary fixing operation, the field edge 2a located at the end has one end portion of the sheet material 5 between the bottom surface of the field edge 2a and the sandwiching portion 32 as shown in FIGS. 14 (A) and 14 (B). The temporary fixing tool 3 is hooked so as to sandwich. In this case, the latching part 31 of the temporary fixing tool 3 is latched by the bending part 23 located outside the field edge 2a.

  Further, as shown in FIG. 15A, the other edge of the sheet material 5 is provided between the first clamping part 32 and the second clamping part 35 of the temporary fixing tool 3A at the field edge 2b located at the center. The temporary fixing tool 3A is hooked in a state where is inserted. In this case, the latching part 31 of the temporary fixing tool 3A is latched by the bending part 23 located inside the field edge 2b.

  Next, one end of the temporarily fixed sheet material 5 is permanently fixed (process P42). Specifically, the screw member 61 passes through the through hole 320 of the clamping portion 32 of the temporary fixing tool 3 and penetrates the bottom portion 21 of the field edge 2a, so that one end portion of the sheet material 5 is permanently fixed. . Here, only the main fixing to the field edge 2a is performed, and the main fixing to the field edge 2b is performed later. That is, the main fixing to the field edge 2b is performed in a fixing operation of another sheet material 5 to the field edge 2b and the field edge 2c, as will be described later.

  Since the fixing work for one sheet material 5 is performed, for example, at a pitch of 300 mm, the processes P3 and P4 are repeated until the necessary fixing work is completed within one span (NO in the determination process P5). When performing the fixing operation at the next position within one span, if the roll holding member 4 is moved to the vicinity of the next position, even if the bucket 81 of the aerial work vehicle 8 has to be lowered once. The remaining roll portion 50 of the sheet material 5 can be temporarily placed in the air. The rod-shaped member 43 of the roll holding member 4 may be simply slid on the adjacent field edge 2 or may be configured to be able to roll.

  When the necessary fixing work is completed within one span (YES in determination process P5), it is determined whether or not all the fixing work has been completed (process P6). If all the fixing operations have not been completed (NO in determination step P6), the roll holding member 4 is transferred onto the next edge 2 (step P7), and the above steps P3 and P4 are repeated.

  Here, the fixing operation of the sheet material 5 to the central field edge 2b and the field edge 2c located at the other end shown in FIG. 8 will be described. Also in this case, first, the temporary fixing of the sheet material 5 is performed using the temporary fixing tools 3 and 3A (process P41). However, as described above, when the fixing operation of the adjacent sheet material 5 is completed, the temporary fixing tool is already in the state where the end portion of the adjacent sheet material 5 is already sandwiched by the central field edge 2b. 3A is hooked. Therefore, when temporarily fixing one end of the sheet material 5 to the field edge 2b, as shown in FIG. 15A, the bottom surface of the field edge 2b and the first clamping part 32 of the temporary fixing tool 3A The temporary fixing tool 3A may be inclined so that a gap is left between them, and one end portion of the sheet material 5 may be sandwiched between the gaps.

  Similarly to the field edge 2a, the temporary fixing tool 3 is hooked on the field edge 2c so that the other end of the sheet material 5 is sandwiched between the bottom surface of the field edge 2c and the clamping part 32. Also in this case, the latching part 31 of the temporary fixing tool 3 is latched by the bending part 23 located outside the field edge 2c. That is, the temporary fixing tool 3 hooked on the field edge 2c is used in a state where it is horizontally reversed from the temporary fixing tool 3 used for the field edge 2a.

  When the sheet material 5 is temporarily fixed to the field edges 2b and 2c, the sheet material 5 is permanently fixed (process P42). For the field edge 2c, as in the case of the field edge 2a, the screw member 61 passes through the bottom hole 21 of the field edge 2c through the through-hole 320 of the clamping part 32 of the temporary fixing tool 3. The other end of the sheet material 5 is permanently fixed. For the field edge 2b, the screw member 61 passes through the bottom hole 21 of the field edge 2b through the through hole 320 of the first holding part 32 and the through hole 350 of the second holding part 35 of the temporary fixture 3A. Thus, the one end portion of the target sheet material 5 and the other end portion of the sheet material 5 adjacent thereto are permanently fixed.

  When the fixing work for all the sheet materials 5 is completed (YES in determination step P6), the mounting work for the sheet materials 5 is finished. Also in the present embodiment, the fall prevention member 62 shown in the first embodiment may be fixed to the field edges 2a, 2b, 2c.

  As described above, according to the present embodiment, since the temporary fixing tools 3 and 3A and the roll holding member 4 are used, the fixing work of the sheet material 5 can be performed by one person. That is, in Embodiment 1 described above, since the screw member 61 is inserted directly into the soft sheet material 5, a tensile force must be applied to the sheet material 5 at the time of fixing. Therefore, in the seat mounting method of the first embodiment, cooperation work by two workers is necessary. If the torque of the impact (electric driver) is not adjusted, the head of the screw member 61 may penetrate the sheet material 5.

  On the other hand, in the present embodiment, the temporary fixing tools 3 and 3A are also used for the main fixing by the screw member 61, so that an operation of applying a tensile force and adjustment of impact torque are unnecessary. Moreover, since the roll part 50 of the sheet material 5 can be held at a high place by supporting the roll holding member 4 on the field edge 2, the fixing work of the sheet material 5 is performed by one operator. be able to.

  Moreover, since the temporary fixing tools 3 and 3A utilize the groove shape of the field edge 2 marketed and the convex part 34 fitted to the recessed part 24 of the field edge 2 is provided, the sheet material 5 is temporarily fixed. The strength of can be increased. In addition, as long as the convex part 34 of the temporary fixing tools 3 and 3A fits the recessed part 24 of the field edge 2, all are not limited to the shape as shown in figure.

  Moreover, since the roll holding member 4 only suspends and holds the roll portion 50 of the sheet material 5, the roll portion 50 can be held at a high place without damaging the sheet material 5.

  In the present embodiment, an example in which the sheet material 5 is fixed one by one when the two sheet materials 5 are attached to the three field edges 2 forming a pair is shown. The member 4 may be bridged over the field edges 2a and 2b and the field edges 2b and 2c, respectively, and the two sheet materials 5 may be fixed in parallel.

  In each embodiment described above, the work for attaching the sheet material 5 along the lower surface of the roof 11 can be easily and safely performed on the aerial work vehicle 8. Moreover, since an internal scaffold is not required, the construction of the sheet material 5 can be performed at low cost.

  Further, according to each embodiment, the plurality of sheet materials 5 (sheet portions 5A) are arranged separately, and the exhaust heat of the radiant heat from the roof is simply adjusted by adjusting the arrangement positions of the air supply means and the exhaust means. And ventilation of the work space can be performed efficiently. In other words, exhaust heat and ventilation in the factory can be easily performed without installing a ceiling under the roof of the factory. As a result, the working environment in the factory can be easily improved.

  In each embodiment, the extending direction of the field edge 2 is orthogonal to the extending direction of the beam 17, but may be the same as the extending direction of the beam 17.

  Further, in each embodiment, the two sheet members 5 are arranged so as to overlap each other, so that the group of sheet portions 5A is configured. However, even if each sheet material 5 configures the sheet portion 5A. Good. In this case, the temporary fixing tool 3A shown in the second embodiment is not necessary.

  In the second embodiment, the field edge 2 is a so-called double bar, but it may be a single bar having a narrower width. In this case, since only one concave portion 24 is provided in the bottom portion 21 of the field edge 2, each of the sandwiching portions 32 and 35 of the temporary fixtures 3 and 3A shown in the second embodiment has only one convex portion. It only has to have.

  In the example of FIG. 1, two supply fans 137 and two exhaust fans 134 are provided, but it is sufficient that at least one supply fan is provided. In this embodiment, a mechanically driven air supply fan 137 is provided as an air supply means for promoting exhaust from the exhaust fan 134. However, the air supply means may be only the air supply gallery 133 that performs natural air supply.

  In each embodiment, the factory has been described as an example, but the present invention can be applied to a building other than the factory as long as the building does not have a ceiling.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
