Insulation sheet installation structure

Abstract

When installing an insulation sheet between the roof and the beams supporting the roof, a challenge is reducing moisture between the roof and the insulation sheet. [Solution] The sheet locking members 20 are used to lock both ends of the shorter side portions of the lower insulation sheet 1 and the upper insulation sheet 2 to the first beam members 10a and 10b. The lower insulation sheet 1 is laid so as to pass below the sheet support member 5 and above the lower wire 41, and the upper insulation sheet 2 is placed above the upper wire 40. By laying the lower insulation sheet 1 and the upper insulation sheet 2 so as to overlap by a predetermined length, a gap of a predetermined length is created between the lower insulation sheet 1 and the upper insulation sheet 2.

Description

Technical Field

[0001] The present invention relates to a heat insulation sheet laying structure that reduces moisture between a roof and a heat insulation sheet while maintaining a heat insulation effect.

Background Art

[0002] Conventionally, factories, warehouses, etc. often have a folded plate roof using a roof material obtained by bending a metal plate into a corrugated shape. When such a folded plate roof is exposed to sunlight and becomes hot, the temperature inside the factory or warehouse rises due to radiant heat. Therefore, a technique is known in which a heat insulation sheet is laid between the folded plate roof and the beam supporting the folded plate roof to suppress the temperature rise inside the factory or warehouse (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the case of the above Patent Document 1, since the heat insulation sheet is laid without a gap on the upper part of the beam supporting the folded plate roof, moisture accumulates in the space between the folded plate roof and the heat insulation sheet. For example, when a heating appliance is used in a building such as a warehouse where heating is difficult to be effective, condensed water is generated in the space between the folded plate roof and the heat insulation sheet. Then, this condensed water gradually leaks out from between the heat insulation sheets, resulting in a problem that the cardboard boxes and products inside the factory or warehouse get wet.

[0005] The present invention has been made to solve the above problems (issues) of the prior art, and an object thereof is to provide a heat insulation sheet laying structure that reduces moisture between a roof and a heat insulation sheet when the heat insulation sheet is laid between the roof and the beam supporting the roof.

Means for Solving the Problems

[0007] Furthermore, the present invention is characterized in that, in the above invention, the first wire is fixed to the beam member through a locking hole provided on the upper part of a predetermined wire locking member, and the second wire, which is arranged adjacent to the first wire, is fixed to the beam member by a fixing part provided on the lower part of the wire locking member.

[0008] Furthermore, the present invention is characterized in that, in the above invention, the sheet support member is provided in the overlapping portion between the first heat insulating sheet laid on the upper surface of the first wire and the second heat insulating sheet laid on the upper surface of the second wire.

[0009] Furthermore, the present invention is characterized in that, in the above invention, the sheet support member has a main body member having the shape of a hollow cylinder or hollow polygonal prism with a wire groove for passing the wire through, and a cover member that covers the wire groove. [Effects of the Invention]

MODE FOR CARRYING OUT THE INVENTION

[0012] Hereinafter, embodiments of the heat insulation sheet laying structure according to the present invention will be described in detail based on the drawings.

[0013] [Embodiment 1] [Overview of Heat Insulation Sheet Laying Structure] The overview of the heat insulation sheet laying structure according to Embodiment 1 will be described. FIG. 1 is a diagram showing the overview of the heat insulation sheet laying structure according to Embodiment 1. In the diagram showing this overview, the wall surfaces constituting the building are not shown in order to make the explanation easier to understand. As shown in FIG. 1, in order to support a folded-plate roof (not shown), a plurality of legs 110 are provided on a base (not shown) to set up columns for the building.

[0014] Then, first beam members 10a and 10b are installed between the upper ends of the legs 110 to provide a beam, and second beam members 11a and 11b are provided so as to be orthogonal to the first beam members 10a and 10b, constituting a rectangular beam which is an example of a beam shape. Upper wires 40a, 40b, 40c (hereinafter may be collectively referred to as upper wire 40) and lower wires 41a, 41b (hereinafter may be collectively referred to as lower wire 41) are installed at a predetermined interval between the second beam members 11a and 11b.

[0015] As shown in FIG. 2, one end of a turnbuckle 22a is fixed to a locking hole 21a provided at the upper part of a wire locking member 21 for the upper wire 40a, and one end of the upper wire 40a is fixed to the other end of the turnbuckle 22a. Then, the other end of the upper wire 40a is fixed to the locking hole 21a of the wire locking member 21 fixed to a second beam member 11b (not shown). Thereafter, by adjusting the turnbuckle 22a, tension is applied to the upper wire 40a so that the upper wire 40a does not sag. Note that the upper wires 40b and 40c are also installed in the same manner as the upper wire 40a.

[0016] Furthermore, as shown in Figure 3, the lower wire 41a is secured by fixing one end of the turnbuckle 22b to the fixing portion 21b at the bottom of the wire locking member 21, and fixing one end of the lower wire 41a to the other end of the turnbuckle 22b. The other end of the lower wire 41a is then secured to the fixing portion 21b of the wire locking member 21, which is fixed to a second beam member 11b (not shown). Subsequently, tension is applied to the lower wire 41a by adjusting the turnbuckle 22b to prevent it from sagging. The lower wire 41b is installed in the same manner as the lower wire 41a. Although the case where the lower wire 41 is secured to the fixing portion 21b of the wire locking member 21 has been described, the lower locking hole may be provided at the bottom of the wire locking member 21, and the lower wire 41 may be secured to the lower locking hole.

[0017] The sheet support member 5 is attached to the upper wire 40. As shown in Figure 4, the sheet support member 5 has a main body member 5a, a wire groove 5b, and a cover member 5c. The main body member 5a is, for example, a cylindrical shape made of polyethylene resin or polypropylene resin. Note that the sheet support member 5 does not have to be cylindrical; it may also be in the shape of a hollow polygonal prism with the central part cut out.

[0018] Furthermore, the wire groove 5b is a groove provided in the main body member 5a for fitting the upper wire 40. The wire groove 5b may be formed by removing a portion of the cylindrical part of the main body member 5a to create a C-shape, with the removed portion serving as the wire groove 5b. The cover member 5c is a cover that covers the wire groove 5b and is fixed to the main body member 5a with adhesive or adhesive tape. The sheet support member 5 is installed in the area where the lower insulation sheet 1 and the upper insulation sheet 2 overlap by inserting the upper wire 40 into the wire groove 5b of the sheet support member 5 and fixing the cover member 5c to the main body member 5a. The length of the sheet support member 5 is 50 mm to 100 mm, and the diameter of the main body member 5a of the sheet support member 5 is 20 mm to 50 mm.

[0019] The lower insulation sheet 1 is secured to the first beam members 10a and 10b at both ends of the shorter side portion of the insulation sheet using the sheet locking member 20. For example, as shown in Figure 5, the shorter side portion of the lower insulation sheet 1 is sandwiched between the first beam member 10a and the sheet locking member 20 and secured by the sheet locking member 20. The lower insulation sheet 1 is laid so as to pass below the sheet support member 5 and above the lower wire 41. On the other hand, the upper insulation sheet 2 is secured to the first beam members 10a and 10b at both ends of the shorter side portion of the insulation sheet using the sheet locking member 20 and laid on top of the upper wire 40. The securing of the upper insulation sheet 2 is the same as that of the lower insulation sheet 1.

[0020] Thus, in the insulation sheet construction structure according to Embodiment 1, when an insulation sheet is installed to cover a rectangular beam by laying a lower insulation sheet 1 and an upper insulation sheet 2 and creating a gap between the lower insulation sheet 1 and the upper insulation sheet 2 that is approximately the same length as the diameter of the sheet support member 5, moisture in the space above the insulation sheet can escape through the gap provided between the lower insulation sheet 1 and the upper insulation sheet 2, thereby preventing excessive moisture in the space above the insulation sheet.

[0021] <Installation of lower insulation sheet 1 and upper insulation sheet 2> Next, the installation of the lower insulation sheet 1 and the upper insulation sheet 2 will be described in detail. Figure 6 is a diagram showing an example of the insulation sheet installation structure as seen from the AA' plane of Figure 1. As shown in Figure 6, the lower insulation sheet 1 is installed by using sheet locking members 20 to lock both ends of the shorter side portion of the insulation sheet to the first beam members 10a and 10b. The lower insulation sheet 1 is installed by passing the lower insulation sheet 1, which is locked by the sheet locking member 20 of the first beam member 10a, under the lower part of the sheet support member 5 fixed to the upper wire 40a, onto the upper part of the lower wire 41a, under the lower part of the sheet support member 5 fixed to the upper wire 40b, onto the upper part of the lower wire 41b, under the lower part of the sheet support member 5 fixed to the upper wire 40c, and then locking it with the sheet locking member 20 of the first beam member 10b.

[0022] The upper insulation sheet 2, like the lower insulation sheet 1, is secured to the first beam members 10a and 10b at both ends of the shorter side portion of the insulation sheet using sheet locking members 20. The upper insulation sheet 2 is laid by passing the upper insulation sheet 2, which is secured by the sheet locking member 20 of the first beam member 10a, over the top of the sheet support member 5 fixed to the upper wire 40a, over the top of the sheet support member 5 fixed to the upper wire 40b, over the top of the sheet support member 5 fixed to the upper wire 40c, and then securing it with the sheet locking member 20 of the first beam member 10b.

[0023] <Example of construction using three insulation sheets> Next, we will explain an example of construction using three insulation sheets. Figure 7 shows an example of construction using three heat-shielding sheets. Here, we will explain the case where a rectangular beam is covered using three insulation sheets: lower insulation sheets 1a and 1b and upper insulation sheet 2.

[0024] As shown in Figure 7, the lower insulation sheet 1a is laid adjacent to the first beam member 10b. The lower insulation sheet 1a is laid above the lower wire 41a and below the sheet support member 5. Then, the upper insulation sheet 2 is laid. The upper insulation sheet 2 is laid above the upper wire 40a and above the sheet support member 5.

[0025] Next, the lower insulation sheet 1b is laid. The lower insulation sheet 1b is laid above the lower wire 41a and below the sheet support member 5. The lower insulation sheets 1a, 1b and the upper insulation sheet 2 overlap by a predetermined width when viewed from above (from above in the drawing). The width of the overlapping area is, for example, 50 mm to 100 mm.

[0026] As described above, by laying the insulation sheets, it is possible to create a predetermined gap between the lower insulation sheets 1a and 1b and the upper insulation sheet 2. Here, we have described the case in which two lower insulation sheets 1 and one upper insulation sheet 2 are used, but it is also possible to lay the upper insulation sheet 2 in the part adjacent to the first beam member 10a, lay the lower insulation sheet 1 next to it, and finally lay the upper insulation sheet 2.

[0027] <Example of installation using 5 insulation sheets> Next, we will describe an example of construction using five insulation sheets. Figure 8 shows an example of construction using five heat-shielding sheets. As shown in Figure 8, the lower insulation sheet 1a is laid adjacent to the first beam member 10b. The lower insulation sheet 1a is laid above the lower wire 41a and below the sheet support member 5.

[0028] Next, the upper insulation sheet 2a is laid. The upper insulation sheet 2a is laid on top of the upper wire 40a and on top of the sheet support member 5. After that, the upper insulation sheet 2b is laid. The upper insulation sheet 2b is laid on top of the upper wire 40a and on top of the sheet support member 5, with an overlapping area of ​​a predetermined width between it and the upper insulation sheet 2a. After that, the upper insulation sheet 2c is laid. The upper insulation sheet 2c is laid on top of the upper wire 40a and on top of the sheet support member 5, with an overlapping area of ​​a predetermined width between it and the upper insulation sheet 2b. The predetermined width of the overlapping area between the upper insulation sheets 2a and 2b and the upper insulation sheets 2b and 2c is, for example, 50 mm to 100 mm.

[0029] Next, the lower insulation sheet 1b is laid. The lower insulation sheet 1b is laid on top of the lower wire 41a and below the sheet support member 5. The lower insulation sheet 1a and the upper insulation sheet 2a, and the upper insulation sheet 2c and the lower insulation sheet 1b, are arranged to overlap by a predetermined width when viewed from above (from above in the drawing). The predetermined width of the overlapping area is, for example, 50 mm to 100 mm.

[0030] As described above, by laying the insulation sheets, it is possible to create a predetermined gap between the lower insulation sheets 1a and 1b and the upper insulation sheets 2a and 2c. Here, we have described the case in which two lower insulation sheets 1 and three upper insulation sheets 2 are used, but it is also possible to lay the upper insulation sheet 2 in the part adjacent to the first beam member 10a, lay three lower insulation sheets 1 next to it, and then lay the upper insulation sheet 2 last.

[0031] Furthermore, in order to create a wider gap between the lower insulation sheet 1 and the upper insulation sheet 2, the lower insulation sheet 1 and the upper insulation sheet 2 may be laid alternately.

[0032] As described above, in this embodiment 1, the lower insulation sheet 1 and the upper insulation sheet 2 are secured to the first beam members 10a and 10b at both ends of the shorter side portion of the insulation sheet using the sheet locking member 20. The lower insulation sheet 1 is laid so as to pass below the sheet support member 5 and above the lower wire 41, and the upper insulation sheet 2 is laid on top of the upper wire 40. This makes it possible to create a gap of a predetermined length between the lower insulation sheet 1 and the upper insulation sheet 2, maintaining the insulation effect of the insulation sheet and allowing moisture in the space between the corrugated roof and the insulation sheet to escape.

[0033] [Embodiment 2] By the way, in Embodiment 1 described above, the lower insulation sheet 1 is laid so as to pass under the sheet support member 5 and over the lower wire 41, and the upper insulation sheet 2 is laid on top of the upper wire 40, and a gap is created between the lower insulation sheet 1 and the upper insulation sheet 2 by the sheet support member 5. However, in Embodiment 2, a case is described in which gaps are created between the insulation sheets by laying the insulation sheets in a wave-like pattern, passing them alternately over the top and bottom of the wire.

[0034] Figure 9 shows an overview of the insulation sheet laying structure according to Embodiment 2. Note that parts similar to those in Embodiment 1 are denoted by the same reference numerals, and their detailed descriptions are omitted.

[0035] As shown in Figure 9, wires 51, 52, 53, 54, and 55 (hereinafter sometimes collectively referred to as wire 50) are installed at predetermined intervals between the second beam members 11a and 11b. Specifically, one end of wire 50 is fixed to the wire locking member 21 of the second beam member 11a, and the other end is fixed to the turnbuckle 22. The turnbuckle 22 is fixed to the wire locking member 21 of the second beam member 11b, and tension is applied to the wire 50 by adjusting the turnbuckle 22 to prevent it from sagging.

[0036] The insulation sheet 3 is secured to the first beam members 10a and 10b at both ends of the shorter side portion of the insulation sheet using the sheet locking member 20. When laying the insulation sheet 3, it is laid by placing it on top of wire 51, passing it under wire 52, placing it on top of wire 53, passing it under wire 54, and placing it on top of wire 55.

[0037] Similar to insulation sheet 3, insulation sheet 4 is secured to the first beam members 10a and 10b at both ends of the longer portion of the insulation sheet using the sheet locking member 20. However, unlike insulation sheet 3, insulation sheet 4 is laid by passing it under wire 51, placing it on top of wire 52, passing it under wire 53, placing it on top of wire 54, and passing it under wire 55. Insulation sheet 3 and insulation sheet 4 are laid so that there is no overlapping area.

[0038] On the surfaces where insulation sheet 3 and insulation sheet 4 are adjacent, one insulation sheet will be laid on the upper part of the wire 50 and the other insulation sheet on the lower part of the wire 50. A sheet support member 6 is installed on the wire 50 to support the insulation sheet at the lower part of the wire 50.

[0039] Here, the shape of the sheet support member 6 will be explained using Figure 10. As shown in Figure 10(a), the sheet support member 6 has a support upper part 6a, a support intermediate part 6b, and a support lower part 6c. As shown in Figure 10(b), the support upper part 6a and the support lower part 6c are provided in different directions with respect to the plane of the support intermediate part 6b. As shown in Figure 10(c), the support intermediate part 6b has a cutout for hooking onto the wire 50. The support intermediate part 6b also has a predetermined length L.

[0040] This sheet support member 6 is used to support the insulation sheet that is passed under the wire 50 so that it does not sag beyond a predetermined length. For example, taking the wire 53 as an example, the insulation sheet 3 is placed on top of the sheet support member 6 installed on the wire 53. Then, the insulation sheet 4 is passed under the wire 53 and placed on top of the lower support portion 6c of the sheet support member 6. As a result, the dimension of the gap between the insulation sheet 3 and the insulation sheet 4 is approximately equal to the length of the intermediate support portion 6b. The length of the intermediate support portion 6b is between 20 mm and 50 mm.

[0041] Although Figure 9 illustrates the installation of insulation sheets 3 and 4, multiple insulation sheets are similarly installed to cover the entire rectangular frame.

[0042] As described above, in this embodiment 2, when the insulation sheet 3 is laid on top of the wire 50 and the insulation sheet 4 passes under the wire 50, or when the insulation sheet 3 is laid on top of the wire 50 and the insulation sheet 4 passes under the wire 50, a sheet support member 6 is provided on the adjacent surfaces of the insulation sheet 3 and the insulation sheet 4 to maintain a predetermined gap between the insulation sheet 3 and the insulation sheet 4. This maintains the insulation effect of the insulation sheet and allows moisture to escape from the space between the corrugated roof and the insulation sheet.

[0043] [Embodiment 3] By the way, in the above embodiment 2, the insulating sheets of insulating sheet 3 or insulating sheet 4 that pass under the wire 50 were supported by the sheet support member 6 on adjacent surfaces. However, in embodiment 3, we will describe a case in which the entire lower part of the insulating sheet of insulating sheet 3 or insulating sheet 4 that passes under the wire 50 is supported by the sheet support member 7.

[0044] Figure 11 is a diagram showing an overview of the insulation sheet laying structure according to Embodiment 3. Parts equivalent to those in the insulation sheet laying structure according to Embodiment 2 are denoted by the same reference numerals, and their detailed descriptions are omitted.

[0045] As shown in Figure 11, the insulation sheet 3 is secured to the first beam members 10a and 10b at both ends of the longer portion of the insulation sheet using the sheet locking member 20, similar to Embodiment 1. When laying the insulation sheet 3, it is laid by placing it on top of wire 51, passing it under wire 52, placing it on top of wire 53, passing it under wire 54, and placing it on top of wire 55.

[0046] Similar to insulation sheet 3, insulation sheet 4 is secured to the first beam members 10a and 10b at both ends of the longer portion of the insulation sheet using the sheet locking member 20. However, unlike insulation sheet 3, insulation sheet 4 is laid by passing it under wire 51, placing it on top of wire 52, passing it under wire 53, placing it on top of wire 54, and passing it under wire 55. Insulation sheets 3 and 4 are laid without overlap.

[0047] On the surfaces where insulation sheet 3 and insulation sheet 4 are adjacent, one insulation sheet will be laid on the upper part of the wire 50 and the other insulation sheet on the lower part of the wire 50. A sheet support member 7 is installed on the wire 50 to support the insulation sheet at the lower part of the wire 50.

[0048] Here, the shape of the sheet support member 7 will be explained using Figure 12. As shown in Figure 12(a), the sheet support member 7 has a support upper part 7a, a support intermediate part 7b, and a support lower part 7c. As shown in Figure 12(b), the support upper part 7a and the support lower part 7c are provided in different directions relative to the plane of the support intermediate part 7b. As shown in Figure 12(c), the support intermediate part 7b has a cutout for hooking onto the wire 50. The support intermediate part 7b also has a predetermined length L. The support lower part 7c is structured to support the insulation sheet, which passes under the wire 50, along the entire short side of the insulation sheet.

[0049] This sheet support member 7 is used to support the insulation sheet that is passed under the wire 50 so that it does not sag beyond a predetermined length. For example, taking the wire 53 as an example, the insulation sheet 3 is placed on top of the sheet support member 7 installed on the wire 53. Then, the insulation sheet 4 is passed under the wire 53 and placed on top of the lower support portion 7c of the sheet support member 7. As a result, the gap between the insulation sheet 3 and the insulation sheet 4 is approximately the length of the support intermediate portion 7b, and the insulation sheet that is passed under the wire 50 can be laid without sagging in the short-side direction. The length of the support intermediate portion 7b is 20 mm to 50 mm.

[0050] Although Figure 11 illustrates the installation of insulation sheets 3 and 4, multiple insulation sheets are similarly installed to cover the entire rectangular frame.

[0051] As described above, in this embodiment 3, when the insulation sheet 3 is laid on top of the wire 50 and the insulation sheet 4 passes under the wire 50, or when the insulation sheet 3 is laid on top of the wire 50 and the insulation sheet 4 passes under the wire 50, sheet support members 7 are provided on adjacent surfaces of the insulation sheet 3 and insulation sheet 4 to support the entire lower part of the insulation sheet that passes under the wire 50, thereby preventing the insulation sheet from loosening and maintaining a predetermined gap between the insulation sheet 3 and insulation sheet 4. This maintains the insulation effect of the insulation sheet and allows moisture to escape from the space between the corrugated roof and the insulation sheet.

[0052] In embodiments 2 and 3 described above, the sheet support member 6 had a support upper part 6a and the sheet support member 7 had a support upper part 7a, but the support upper parts 6a and 7a are not required. Also, the support lower part 7c of the sheet support member 7 is a flat plate shape, but this shape does not have to be plate-shaped and may be polygonal or round. Furthermore, the support lower parts 6c and 7c of the sheet support member 6 and the sheet support member 7 may be clip-shaped to hold the heat insulating sheet.

[0053] [Embodiment 4] By the way, in embodiments 2 and 3 described above, the heat insulation sheet was laid by hooking the sheet support member 6 or sheet support member 7 onto the wire 50. Embodiment 4 describes a case where a sheet support member 8 is provided near the wire 50 to support the heat insulation sheet that passes under the wire 50.

[0054] Figure 13 is a diagram showing an overview of the insulation sheet laying structure according to Embodiment 4. Note that parts equivalent to those in the insulation sheet laying structures according to Embodiments 2 and 3 are denoted by the same reference numerals, and their detailed descriptions are omitted.

[0055] As shown in Figure 13, the insulation sheet 3 is secured to the first beam members 10a and 10b at both ends of the longer portion of the insulation sheet using the sheet locking member 20, similar to Embodiment 2. When laying the insulation sheet 3, it is laid by placing it on top of wire 51, passing it under wire 52, placing it on top of wire 53, passing it under wire 54, and placing it on top of wire 55.

[0056] Similar to insulation sheet 3, insulation sheet 4 is secured to the first beam members 10a and 10b at both ends of the longer portion of the insulation sheet using the sheet locking member 20. However, unlike insulation sheet 3, insulation sheet 4 is laid by passing it under wire 51, placing it on top of wire 52, passing it under wire 53, placing it on top of wire 54, and passing it under wire 55. Insulation sheets 3 and 4 are laid without overlap.

[0057] On the surfaces where insulation sheet 3 and insulation sheet 4 are adjacent, one insulation sheet will be laid above the wire 50 and the other below the wire 50. A sheet support member 8 is installed on the wire 50 to support the insulation sheet below the wire 50. At this time, the sheet support member 8 is installed on the right side in the direction from the wire locking member 21 fixed to the second beam member 11a of the wire 50 toward the wire locking member 21 fixed to the second beam member 11b.

[0058] Here, the shape of the sheet support member 8 will be explained using Figure 14. Figure 14 shows an example of the structure of the sheet support member 8 shown in Figure 13. As shown in Figure 14, the sheet support member 8 has an upper clip portion 8a, a support intermediate portion 8b, and a lower clip portion 8c. The upper clip portion 8a and the lower clip portion 8c are provided in different directions with respect to the plane of the support intermediate portion 8b. The support intermediate portion 8b has a predetermined length L.

[0059] This sheet support member 8 is used to support the insulation sheet placed on top of the wire 50 and the insulation sheet passed through the bottom of the wire 50 so that the gap between them is a predetermined length. For example, taking the wire 53 as an example, the insulation sheet 3 placed on top of the wire 53 is clamped using the upper clip portion 8a of the sheet support member 8. Then, the insulation sheet 4 is passed through the bottom of the wire 53 and clamped using the lower clip portion 8c of the sheet support member 8. As a result, the dimension of the gap between the insulation sheet 3 and the insulation sheet 4 becomes approximately the length of the support intermediate portion 8b. The length of the support intermediate portion 8b is between 20 mm and 50 mm.

[0060] As described above, in this embodiment 4, when the insulation sheet 3 is laid on top of the wire 50 and the insulation sheet 4 passes under the wire 50, or when the insulation sheet 3 is laid on top of the wire 50 and the insulation sheet 4 passes under the wire 50, a sheet support member 8 is provided near the wire 50 on adjacent surfaces of the insulation sheet 3 and insulation sheet 4. By sandwiching the insulation sheet 3 and insulation sheet 4 with the upper clip portion 8a or the lower clip portion 8c and laying the insulation sheet, it is possible to maintain a predetermined gap between the insulation sheet 3 and insulation sheet 4, thereby maintaining the insulation effect of the insulation sheet and allowing moisture in the space between the corrugated roof and the insulation sheet to escape.

[0061] <Variation> By the way, in embodiments 2 to 4 described above, the installation structure for supporting the insulation sheets 3 and 4 using sheet support members 6, 7, and 8 on the adjacent surfaces of the insulation sheets 3 and 4 was explained. However, in modification 1, the installation structure in which sheet support members 6, 7, and 8 are not used will be explained.

[0062] Figure 15 is a diagram showing an overview of a modified insulation sheet laying structure. Note that parts equivalent to those in the insulation sheet laying structures of embodiments 2, 3, and 4 are denoted by the same reference numerals, and their detailed descriptions are omitted.

[0063] As shown in Figure 15, the insulation sheet 3 is secured to the first beam members 10a and 10b at both ends of the longer portion of the insulation sheet using the sheet locking member 20, similar to Embodiment 2. When laying the insulation sheet 3, it is laid by placing it on top of wire 51, passing it under wire 52, placing it on top of wire 53, passing it under wire 54, and placing it on top of wire 55.

[0064] Similar to insulation sheet 3, insulation sheet 4 is secured to the first beam members 10a and 10b at both ends of the longer portion of the insulation sheet using the sheet locking member 20. However, unlike insulation sheet 3, insulation sheet 4 is laid by passing it under wire 51, placing it on top of wire 52, passing it under wire 53, placing it on top of wire 54, and passing it under wire 55. Insulation sheets 3 and 4 are laid without overlap.

[0065] On the surfaces where insulation sheet 3 and insulation sheet 4 are adjacent, one insulation sheet is laid above the wire 50, and the other insulation sheet is laid below the wire 50. Here, the details of the installation of insulation sheet 3 and insulation sheet 4 according to the modified example will be explained. Figure 16 is a diagram showing the details of the insulation sheet installation structure shown in Figure 15.

[0066] As shown in Figure 16, the insulation sheet 3 is laid by passing it under wire 52, on top of wire 53, and under wire 54, while the insulation sheet 4 is laid by placing it on top of wire 52, passing it under wire 53, and on top of wire 54.

[0067] In the modified insulation sheet laying structure, no support is used to hold the insulation sheet in place. Instead, the worker adjusts the slack in the insulation sheet that passes under the wire 50. For example, on the adjacent surfaces of insulation sheet 3 and insulation sheet 4 on wire 53, insulation sheet 3 is placed on top of wire 53, and insulation sheet 4 passes under wire 53. The insulation sheets are laid so that the gap between insulation sheet 3 and insulation sheet 4 is 20 mm to 50 mm. This maintains the insulation effect of the insulation sheet while allowing moisture to escape from the space between the corrugated metal roof and the insulation sheet.

[0068] The configurations illustrated in each of the above embodiments are functional schematics and do not necessarily have to be physically represented as shown. In other words, the distributed and integrated forms of each device are not limited to those shown, and all or part of them can be functionally or physically distributed and integrated in any unit according to various loads and usage conditions.
