MODE FOR CARRYING OUT THE INVENTION

[0011] Embodiments of the present disclosure will be described with reference to the drawings. Note that the following embodiments are only a part of various embodiments of the present disclosure. Also, the following embodiments can be variously modified according to design and the like as long as the object of the present disclosure can be achieved. The drawings referred to below are schematic drawings, and the dimensional ratios of the components in the drawings do not necessarily reflect the actual dimensional ratios. The arrows indicating directions in the drawings are only shown for easy understanding of the description and do not accompany an entity.

[0012] (1) Overview As shown in Fig. 1, the folded-plate roof structure 6 of the present embodiment includes a folded plate 1, a frame member 2, and a reinforcing member 3. The folded plate 1 includes a valley portion 10 and a pair of half-peak portions 11 that project on both sides of the valley portion 10. The frame member 2 includes a pair of leg portions 20 to which the half-peak portions 11 of the folded plate 1 are attached, and a top plate portion 21 that connects the pair of leg portions 20. The reinforcing member 3 includes a connecting portion 33 fixed to the top plate portion 21 and a contact portion 30 positioned below the connecting portion 33. The reinforcing member 3 is also arranged in a state of being suspended below the top plate portion 21. The contact portion 30 is formed to be vertically movable between a state of being separated from and a state of contacting a member 4 positioned below the reinforcing member 3.

[0013] According to this aspect, in a state where the contact portion 30 moves upward and is separated from the member 4, it is difficult to form a heat bridge, and the heat insulation property is difficult to deteriorate. In a state where the contact portion 30 moves downward and contacts the member 4, the reinforcing member 3 can support and reinforce the frame member 2.

[0014] (2) Details (Embodiment 1) Fig. 1 shows the folded-plate roof structure 6 of the present embodiment. This folded-plate roof structure 6 is a double-folded-plate roof structure. That is, the upper folded plate 1 and the lower folded plate 7 are arranged to face each other in the vertical direction, and the folded-plate roof structure 6 is formed.

[0015] The folded-plate roof structure 6 of the present embodiment is formed by including a folded plate 1, a frame member 2, a reinforcing member 3, and the like.

[0016] <Folded Plate> As shown in Fig. 2, the folded plate 1 is a metal roof material formed by bending a metal plate such as a painted steel plate, a galvanized steel plate, or a Galvalume steel plate (registered trademark), and is formed to be long in the front-rear direction, which is the inclined direction (flow direction) of the roof. The folded plate 1 is formed in a substantially U-shaped cross-section and includes a valley portion 10 and half-peak portions 11 and 12 that project obliquely upward from both side end portions (right end portion and left end portion) of the valley portion 10. A pair of stepped portions 101 are formed in the valley portion 10 over substantially the entire length in the longitudinal direction of the folded plate 1 by bending.

[0017] One of the mountain sections 11 consists of a slanted side section 110 that protrudes diagonally upward outward (opposite to the valley section 10) from one side end of the valley section 10, a top section 111 that protrudes substantially horizontally outward (opposite to the valley section 10) from the upper end of the slanted side section 110, and a fitting section 112 with a substantially inverted U-shaped cross-section that protrudes upward from the end of the top section 111.

[0018] The other half of the mountain section 12 includes a slanted side section 120 that protrudes diagonally upward outward (opposite to the valley section 10) from the other side end of the valley section 10, a top section 121 that protrudes substantially horizontally outward (opposite to the valley section 10) from the upper end of the slanted side section 120, and a fitting section 122 with a substantially inverted L-shaped cross-section that protrudes upward from the end of the top section 121.

[0019] Furthermore, locking portions 113 and 114 are provided on the slanted side portion 110 of one of the mountain-shaped halves 11. The locking portions 113 and 114 are formed so as to protrude from the back side by bending a part of the slanted side portion 110 in a stepped manner. In addition, one locking portion 113 can be formed above the vertical center of the slanted side portion 110, and the other locking portion 114 can be formed below the vertical center of the slanted side portion 110. In addition, the locking portions 113 and 114 can be formed along the entire length in the longitudinal direction of the folded plate 1.

[0020] Furthermore, locking portions 123 and 124 are also provided on the slanted side portion 120 of the other half of the mountain portion 12. The locking portions 123 and 124 are formed so as to protrude from the back side by bending a part of the slanted side portion 120 in a stepped manner. In addition, one locking portion 123 can be formed above the vertical center of the slanted side portion 120, and the other locking portion 124 can be formed below the vertical center of the slanted side portion 120. Furthermore, the locking portions 123 and 124 can be formed along the entire length in the longitudinal direction of the folded plate 1.

[0021] The lower corrugated sheet 7 can be formed in the same way as the corrugated sheet 1. In other words, the corrugated sheet 1 and the lower corrugated sheet 7 can use the same components.

[0022] <Frame components> Frame member 2 consists of two types: tight frame 2A and insulation fitting 2B. Tight frame 2A is a member used to fix the lower corrugated sheet 7 to the roof underlayment 60. Insulation fitting 2B is a member used to fix the upper corrugated sheet 1 to the tight frame 2A.

[0023] In the following, the leg portion 20 of the frame member 2 includes the leg portion 20A of the tight frame 2A and the leg portion 20B of the insulation fitting 2B. Also, the top plate portion 21 of the frame member 2 includes the top plate portion 21A of the tight frame 2A and the top plate portion 21B of the insulation fitting 2B.

[0024] <<Tight Frame>> As shown in Figure 3, the tight frame 2A is a metal member formed by bending a rectangular (strip-shaped) metal plate, such as a steel plate, and comprises a pair of legs 20A and a top plate 21A. The top plate 21A is rectangular in shape when viewed from above. The pair of legs 20A are formed to protrude diagonally downward outwards (opposite to the top plate 21A) from both side ends (right and left ends) of the top plate 21A. Therefore, the pair of legs 20A are arranged in a V-shape when viewed from the front, and the upper ends of the pair of legs 20A are connected by the top plate 21A.

[0025] Each pair of legs 20A has two engaging portions 22A and 23A. The engaging portions 22A and 23A are formed protruding from the surface of the legs 20A and can be formed, for example, by cutting and bending a part of the legs 20A. In addition, one engaging portion 22A can be formed above the vertical center of the leg 20A, and the other engaging portion 23A can be formed below the vertical center of the leg 20A.

[0026] The tight frame 2A also has a fixing portion 24A. The fixing portion 24A protrudes outward (to the opposite side from the top plate portion 21A) from the lower end of each of the pair of leg portions 20A. The tight frame 2A has multiple interlocking ridges 25A, which are made up of the pair of leg portions 20A and the top plate portion 21A. The multiple interlocking ridges 25A are connected in the left-right direction via the fixing portion 24A. The tight frame 2A is formed to extend in the direction in which the multiple interlocking ridges 25A are aligned.

[0027] The tight frame 2A also has a fixing hole 210A. The fixing hole 210A is formed to penetrate the top plate portion 21A in the vertical direction. The fixing hole 210A is a hole for fixing the connecting portion 33 of the reinforcing member 3.

[0028] In this embodiment, the reinforcing member 3 is not fixed to the tight frame 2A, so the fixing hole 210A is not used.

[0029] <<Insulation fittings>> As shown in Figure 4, the heat insulating bracket 2B is a metal member formed by bending a rectangular (strip-shaped) metal plate, such as a steel plate, and comprises a pair of legs 20B and a top plate 21B. The top plate 21B is rectangular in shape when viewed from above. The pair of legs 20B are formed to protrude diagonally downward outwards (opposite to the top plate 21B) from both side ends (right and left ends) of the top plate 21B. Therefore, the pair of legs 20B are arranged in a V-shape when viewed from the front, and the upper ends of the pair of legs 20B are connected by the top plate 21B.

[0030] Each of the pair of legs 20B has two engaging portions 22B and 23B. The engaging portions 22B and 23B are formed protruding from the surface of the leg portion 20B and can be formed, for example, by cutting and bending a part of the leg portion 20B. In addition, one engaging portion 22B can be formed above the vertical center of the leg portion 20B, and the other engaging portion 23B can be formed below the vertical center of the leg portion 20B.

[0031] The insulating fitting 2B also has locking legs 26B. The locking legs 26B are formed to protrude downward from the lower ends of each of the pair of legs 20B. A claw-like locking portion 27B with a roughly V-shaped cross-section is formed at the lower part of the locking legs 26B, protruding inward (towards the top plate portion 21B). An insulating member 28B is provided on the surface of the locking portion 27B. The insulating member 28B is made of an insulating material with lower thermal conductivity than metal, and can be made of molded products or tapes of plastics such as nylon resin or ABS resin or rubber, for example. The insulating member 28B can be attached to the locking portion 27B by any method such as fitting, bonding or crimping.

[0032] Furthermore, a connecting piece 29B is provided protruding from the outer surface of the locking leg portion 26B (the surface opposite to the top plate portion 21B). The connecting piece 29B is formed in the shape of a rectangular plate when viewed from above, and a connecting bolt 290B that penetrates it in the vertical direction is attached to it.

[0033] The insulation fitting 2B also has a fixing hole 210B. The fixing hole 210B is formed to penetrate the top plate portion 21B in the vertical direction. The fixing hole 210B is a hole for fixing the connecting portion 33 of the reinforcing member 3.

[0034] <Reinforcement device> The reinforcing member 3 is a member for reinforcing the frame member 2. The reinforcing member 3 has a symmetrical shape. The reinforcing member 3 is located between the top plate portion 21 of the frame member 2 and the member 4 provided below the reinforcing member 3, and supports the top plate portion 21 when a load is applied to the top plate portion 21 from above, thereby suppressing deformation of the frame member 2.

[0035] Figure 5 shows a frame member 5 with a reinforcing member. In this embodiment, the frame member 5 with a reinforcing member is formed by attaching the reinforcing member 3 to the insulation fitting 2B. In this frame member 5 with a reinforcing member, the reinforcing member 3 is attached to the insulation fitting 2B before construction.

[0036] Figures 6-9 show the reinforcing member 3 before it is attached to the insulation fitting 2B. The reinforcing member 3 comprises a metal reinforcing member body 34 and an installation part 32 made of rubber or elastomer. The reinforcing member body 34 is formed by bending a metal plate such as a steel plate and comprises a back plate 31, side plates 35, front plate 36 and bottom plate 37. It is preferable that the thickness of the metal plate forming the reinforcing member body 34 is 1.6 mm or more. If it is less than this, the deformation of the reinforcing member body 34 due to the load will be large, making it difficult to transmit the load to the tight frame 2A.

[0037] As shown in Figure 7, the back panel 31 is formed in a flat shape, and support legs 310 are formed at the lower part of both ends in the left-right direction. A space is formed between this pair of support legs 310.

[0038] As shown in Figure 8, the side panels 35 are formed in a flat shape and protrude forward from both the left and right ends of the back panel 31. Contact portions 350 are provided at the upper ends of each of the pair of side panels 35. Each of the pair of contact portions 350 is located near the middle of the pair of side panels 35 in the front-to-back direction.

[0039] As shown in Figure 6, the front panel 36 is formed in a flat shape and protrudes to the right or left from the front ends of each of the pair of side panels 35. The pair of front panels 36 face each other in the left-right direction. The pair of front panels 36 also face the rear panel 31 in the front-rear direction. The lower parts of the pair of front panels 36 are each formed as support legs 360, and the pair of support legs 360 face the support legs 310 of the rear panel 31 in the front-rear direction.

[0040] As shown in Figure 9, the bottom plate 37 is formed to protrude to the right or left from the lower end of each of the pair of side plates 35. The pair of bottom plates 37 are formed in a plate shape and are positioned below the left support legs 310 and 360, and below the right support legs 310 and 360, respectively.

[0041] The front and rear ends of the base plate 37 are formed as inclined portions 370. Each pair of inclined portions 370 is formed to protrude diagonally upward toward the tip (front end or rear end). The inclination angle of each pair of inclined portions 370 is approximately 10° with respect to the horizontal, but is not limited to this.

[0042] Each of the pair of bottom plates 37 is provided with a notch 371. The notch 371 is formed approximately in the center of the bottom plate 37 in the front-to-back direction. In plan view, the notch 371 is formed in an arc shape and opens to the upper surface, lower surface, and inner edge of the bottom plate 37. The notch 371 is intended to avoid protrusions caused by construction marks formed on the lower folded plate 7.

[0043] As shown in Figure 3, a pair of protrusions 211A are provided on the upper surface of the top plate portion 21A of the tight frame 2A. When the lower corrugated sheet 7 is installed on the tight frame 2A, the tops 111 and 121 are pressed by the pair of protrusions 211A, forming a raised installation mark. This installation mark occurs when the lower corrugated sheet 7 is properly installed on the tight frame 2A, but is not formed if the installation is poor. It also makes it easier to locate the tight frame 2A when installing the insulation fittings 2B. Therefore, the notches 371 accommodate and avoid the raised installation marks that form on the tops 111 and 121 of the lower corrugated sheet 7. The insulation fittings 2B are also provided with a pair of protrusions 211B on the top plate portion 21B to form an installation mark.

[0044] Furthermore, by providing the reinforcing body 34 with a pair of bottom plates 37, the lower end surfaces of the pair of support legs 310 and the pair of support legs 360 are prevented from directly contacting the lower corrugated sheet 7, thereby preventing damage to the lower corrugated sheet 7. In addition, even if the reinforcing body 3 is slightly misaligned from its predetermined position, the bottom plates 37 will act to assist in positioning it above the tight frame 2A, ensuring that the load is reliably transmitted to the tight frame 2A and preventing the reinforcing body 3 from sinking too deeply into the lower corrugated sheet 7.

[0045] The reinforcing member 3 is equipped with a connecting portion 33. As shown in Figure 9, the connecting portion 33 is integrally formed with the reinforcing member body 34. The connecting portion 33 comprises a fixing plate 330 and a narrow portion 331.

[0046] The fixing plate 330 is formed in a rectangular shape when viewed from above. The front-to-back dimension of the fixing plate 330 is smaller than the dimension between the back plate 31 and the front plate 36. Also, the left-to-right dimension of the fixing plate 330 is smaller than the dimension between the pair of side plates 35. The fixing plate 330 is located approximately in the center of the reinforcing device 3 in the front-to-back direction, approximately in the center between the pair of side plates 35.

[0047] The fixing plate 330 has a connecting hole 332. The connecting hole 332 is located approximately in the center of the fixing plate 330 in a plan view. The connecting hole 332 penetrates the fixing plate 330 in the vertical direction. A burring portion 333 that protrudes upward is provided at the opening edge of the connecting hole 332. The burring portion 333 is formed by burring during the formation of the connecting hole 332 (see Figures 6 and 7).

[0048] Furthermore, the fixing hole 210B of the insulation fitting 2B is tapered before the reinforcing member 3 is attached, and the burring portion 333 of the reinforcing member 3 and the tapered fixing hole 210B are joined together and crimped. This allows the reinforcing member 3 to be attached to the insulation fitting 2B.

[0049] The narrow section 331 is formed in a rectangular plate shape when viewed from above. The left-right dimension of the narrow section 331 is smaller than the left-right dimension of the fixing plate 330. The front end of the narrow section 331 is connected to the approximate center of the rear end of the fixing plate 330. The rear end of the narrow section 331 is connected to the approximate center of the upper end of the back plate 31. In other words, the fixing plate 330 is provided in a cantilevered configuration using the narrow section 331.

[0050] The mounting portion 32 is made of the same material as the waterproof packing and has cushioning (elasticity). The mounting portion 32 is formed in a flat plate shape and is provided across the entire lower surface of the bottom plate 37, as shown in Figures 10 and 12. Since the inclined portions 370 at the front and rear ends of the bottom plate 37 are inclined diagonally upward, the front and rear ends of the mounting portion 32 are also inclined diagonally upward. The lower surface of the mounting portion 32 is formed as the contact portion 30 of the reinforcing member 3.

[0051] The mounting section 32 can be formed, for example, by attaching a foamed rubber packing of about 2 mm thickness, and is provided to prevent thermal bridging and damage to the lower corrugated sheet 7.

[0052] The reinforcing body 34 has a shape resembling a C-shaped steel channel in plan view, and its simple shape contributes to its maximum size. Furthermore, the space between the pair of side plates 35 of the reinforcing body 34 is designed to allow for the filling of insulation material such as glass wool.

[0053] <Frame component with reinforcing device> The reinforced frame member 5 comprises the frame member 2 and the reinforcement 3. The reinforced frame member 5 shown in Figure 5 is formed by providing the reinforcement 3 to the heat insulation fitting 2B. The reinforcement 3 is provided on the underside of the top plate portion 21B of the heat insulation fitting 2B. The reinforcement 3 is connected to the top plate portion 21B only at the connecting portion 33. Therefore, the reinforcement 3 is positioned below the top plate portion 21B, suspended by the connecting portion 33.

[0054] The reinforcing member 3 and the top plate portion 21B are joined by a crimped portion 50. The crimped portion 50 is a hole formed by crimping a burring portion 333 and a fixing hole 210B. In other words, the connecting hole 332 of the fixing plate 330 is burred to form a burring portion 333 that protrudes from the upper surface.

[0055] The upper surface of the fixing plate 330 of the connecting part 33 is brought into contact with the lower surface of the top plate part 21B, and at the same time, the burring part 333 is inserted into the fixing hole 210B. A jig is inserted from above the fixing hole 210B and crimped to join the parts.

[0056] At this time, the crimped portion 50 is formed in a tapered shape from top to bottom. This joint structure improves the mounting strength between the top plate portion 21B and the reinforcing member 3, ensuring strength that prevents it from coming loose even when subjected to shaking, vibration, or other movements.

[0057] Furthermore, since the crimped portion 50 does not protrude from the upper surface of the top plate portion 21B, the upper surface of the top plate portion 21B is formed as a flat surface.

[0058] In this embodiment, the heat insulation fitting 2B and the reinforcing member 3 are connected by a narrow section 331 with a small width (narrow dimension in the left-right direction), which makes it difficult for the reinforcing member 3 to move in conjunction with the heat insulation fitting 2B.

[0059] Furthermore, the insulation fitting 2B and the reinforcing fitting 3 are connected only by the crimped portion 50. The connecting portion 33, which is connected to the crimped portion 50, is located above the back plate 31, front plate 36, and contact portion 350 of the reinforcing fitting 3, and a gap is created between the insulation fitting 2B and the reinforcing fitting 3, making it difficult for the reinforcing fitting 3 to move in conjunction with the insulation fitting 2B.

[0060] On the other hand, the reinforcing member 3 needs to be in contact with the inside of the insulation fitting 2B to receive the compressive load (positive pressure load) from above and transmit it to the tight frame 2A. Therefore, the contact portion 350, the back plate 31, and the front plate 36 are brought into contact with the underside of the top plate portion 21B to transmit the load to the tight frame 2A. In other words, the width dimensions of the reinforcing member 3 in the left-right direction and the front-rear direction are the maximum dimensions that can be installed on the inside of the top plate portions 21A and 21B of the tight frame 2A and insulation fitting 2B in the left-right direction and front-rear direction, respectively, as this is the area where the frame strength is strongest, so it is optimal to install it at the maximum size. Therefore, in the folded plate roof structure 6 of this embodiment, it is desirable that the reinforcing member 3 be installed in the same position as the top plate portions 21B and 21A of the insulation fitting 2B and the tight frame 2A. In this case, when the back plate 31, front plate 36, and contact portion 350 of the reinforcing member 3 come into contact with the lower surface of the top plate portion 21B due to a compressive load from above, the compressive load can be transmitted to the tight frame 2A on the downward extension of the back plate 31, front plate 36, and side plate 35, so that the reinforcing member 3 can be positioned with the highest possible strength.

[0061] In this embodiment, the inclined portion 370 is processed to an angle of approximately 10° (more specifically, between 10° and 15°). When the insulation fitting 2B tilts in the front-to-back direction, the bottom plate 37 of the reinforcing device 3 is less likely to become stiff, allowing the insulation fitting 2B to move smoothly in the front-to-back direction.

[0062] <Folded plate roof structure> As shown in Figure 1, the corrugated metal roof structure 6 of this embodiment is a double corrugated metal roof structure and comprises a corrugated metal sheet 1, a tight frame 2A, a lower corrugated metal sheet 7, and a frame member 5 with reinforcing members (reinforcing members 3 and heat insulating fittings 2B). The corrugated metal roof structure 6 is formed as follows.

[0063] First, the tight frame 2A is fixed onto the roof substrate 60. At this time, the fixing part 24A of the tight frame 2A is placed on the roof substrate 60, and the fixing part 24A is joined to the roof substrate 60 by welding or other means, thereby fixing the tight frame 2A to the roof substrate 60.

[0064] The roof underlayment 60 is a horizontal member arranged substantially horizontally, and is at least one selected from the group consisting of purlins, girders, beams, and rafters. The tight frame 2A can be arranged along the longitudinal direction of the roof underlayment 60, and the tight frame 2A can be provided over substantially the entire length of the roof underlayment 60 in the longitudinal direction (the direction perpendicular to the slope direction of the roof).

[0065] Next, a single lower corrugated sheet 7 is erected on a plurality of roof underlays 60 arranged in parallel in the direction of the roof slope. At this time, the lower corrugated sheet 7 is positioned so as to overlap the tight frame 2A attached to the roof underlay 60 from above, with the valley portion 10 of the lower corrugated sheet 7 positioned between adjacent interlocking ridge portions 25A of the tight frame 2A, and placed on the roof underlay 60 or on the fixing portion 24A of the tight frame 2A.

[0066] Furthermore, one half of the lower folded plate 7, the peak portion 11, is connected to the adjacent leg portion 20A, and the other half of the lower folded plate 7, the peak portion 12, is connected to the adjacent leg portion 20A. In this case, the upper locking portions 114 and 124 provided on the slanted portions 110 and 120 are locked to the tips (lower ends) of the upper engaging portions 22A provided on the leg portion 20A, and the lower locking portions 113 and 123 provided on the slanted portions 110 and 120 are locked to the tips (lower ends) of the lower engaging portions 23A provided on the leg portion 20A. In this way, the peak portions 11 and 12 on both sides of the lower folded plate 7 are locked to and held by the tight frame 2A. In addition, the top portions 111 and 121 of the peak portions 11 and 12 of the lower folded plate 7 are positioned above the top plate portion 21A of the tight frame 2A.

[0067] In this way, multiple lower corrugated sheets 7 are sequentially placed on the roof base 60. Then, by joining the fitting portions 112 and fitted portions 122 of adjacent lower corrugated sheets 7 in the left-right direction using seam fastening (clasp fastening) to form seam fastening portions 70 and joining them, adjacent lower corrugated sheets 7 in the left-right direction (longitudinal direction of the roof base 60) are laid while connecting them, and a lower corrugated sheet roof can be formed in which peaks 71 and valleys 10 are alternately and continuously connected in the left-right direction.

[0068] After arranging the multiple lower corrugated sheets 7 as described above, the reinforcing frame member 5 is attached. The reinforcing frame member 5 is provided above the lower corrugated sheets 7, corresponding to the position of the tight frame 2A. When attaching the reinforcing frame member 5, first, the insulation fitting 2B, with the spacing of the legs 20B elastically slightly widened, is brought closer to the peak 71 of the lower corrugated roof from above, and the legs 20B are positioned on both sides of the peak 71. After this, the spacing of the legs 20B is narrowed, thereby locking the locking portion 27B of the locking leg 26B to the lower surface of the locking portions 113 and 123 formed on the sides of the peak 71.

[0069] In this case, the engagement portion 27B is engaged with the locking portions 113 and 123 via the insulating member 28B, and the insulating member 28B is interposed between the engagement portion 27B and the locking portions 113 and 123. Therefore, it is possible to prevent a heat bridge between the insulating fitting 2B and the corrugated sheet 1 and lower corrugated sheet 7 connected thereto, and to prevent a decrease in the insulation performance of the roof. In this way, the insulating fitting 2B can be attached by elastically sandwiching and straddling the ridge portion 71.

[0070] As described above, the reinforcing bracket 3 can be positioned at the same time as the insulating bracket 2B is installed. The reinforcing bracket 3 is positioned above the tops 111 and 121 of the lower corrugated sheet 7. Here, the contact portion 30 on the lower surface of the reinforcing bracket 3 does not contact the tops 111 and 121. A gap of 1 to 5 mm is formed between the contact portion 30 and the tops 111 and 121 of the lower corrugated sheet 7.

[0071] Furthermore, the reinforcing member 3 is arranged such that a pair of support legs 310 and a pair of support legs 360 straddle the seam fastening section 70 in the left-right direction. That is, the seam fastening section 70 is positioned between the pair of support legs 310 and between the pair of support legs 360. Here, the front plate 36 has a slanted section 362 at an angle of approximately 45°, and the left-right dimension of the support leg 360 below the slanted section 362 is reduced. This makes it possible to adequately withstand the compressive load from above with the front plate 36 while preventing the support legs 360 from coming into contact with the seam fastening section 70.

[0072] In Figure 1, the seam fastening portion 70 protrudes to the left, but even if the seam fastening portion 70 protrudes to the right and is facing the opposite direction, it can still be positioned between the pair of support legs 310 and 360.

[0073] Multiple reinforcing frame members 5 can be arranged in a row along the longitudinal direction of a single ridge 71. In this case, the reinforcing frame members 5 can be arranged at the same intervals as the tight frames 2A (for example, the intervals between purlins). Furthermore, adjacent reinforcing frame members 5 in a direction perpendicular to the longitudinal direction of the ridge 71 are connected by connecting members 75 with insulation fittings 2B. At this time, the left and right ends of the connecting member 75 are connected to connecting pieces 29B by connecting bolts 290B.

[0074] After arranging the frame members 5 with reinforcing members as described above, the corrugated sheets 1 are installed. First, one corrugated sheet 1 is placed above the lower corrugated sheet 7. At this time, the corrugated sheet 1 is placed over the insulation fittings 2B attached to the lower corrugated sheet 7 from above, and the valley portion 10 of the corrugated sheet 1 is positioned above the joint member 75 between adjacent insulation fittings 2B in the left-right direction. In addition, one half of the corrugated sheet 1, 11 is connected to the insulation fitting 2B adjacent to it, and the other half of the corrugated sheet 1, 12 is connected to the other insulation fitting 2B adjacent to it. In this case, the upper locking portions 114 and 124 provided on the slanted edges 110 and 120 are locked to the tips (lower ends) of the upper engaging portions 22B provided on the leg portion 20B of the insulation fitting 2B, and the lower locking portions 113 and 123 provided on the slanted edges 110 and 120 are locked to the tips (lower ends) of the lower engaging portions 23B provided on the leg portion 20B. In this way, the two halves of the folded plate 1, 11 and 12, are locked to and held by the insulation fitting 2B. Furthermore, the top portions 111 and 121 of the two halves of the folded plate 1, 11 and 12 are positioned above the top plate portion 21A of the insulation fitting 2B.

[0075] In this way, multiple corrugated sheets 1 are sequentially placed on the lower corrugated roof. Then, by joining the fitting portions 112 and fitted portions 122 of adjacent corrugated sheets 1 in the left-right direction using seam fastening (clasp fastening) to form seam fastening portions 130 and joining them, adjacent corrugated sheets 1 are laid while connecting them in the left-right direction (longitudinal direction of the roof base 60), and an upper corrugated roof can be formed in which peaks 131 and valleys 10 are alternately and continuously connected in the left-right direction.

[0076] Furthermore, the insulation performance can be improved by filling the space between the upper corrugated sheet 1 and the lower corrugated sheet 7 with insulation material 133 such as rock wool.

[0077] In the corrugated metal roof structure 6 of this embodiment, the contact portion 30 of the reinforcing member 3 is formed to be vertically movable between a state of separation from the member 4 located below the reinforcing member 3 and a state of contact. That is, the contact portion 30 is formed to be vertically movable between a state of separation from the top portions 111 and 121 of the lower corrugated metal 7, which is the member 4 located below the reinforcing member 3 and a state of contact.

[0078] In this embodiment, under normal conditions (when no load is applied from above to the upper corrugated sheet 1), the contact portion 30 of the reinforcing member 3 is spaced apart from the top portions 111 and 121 of the lower corrugated sheet 7, which is a member 4 located below the reinforcing member 3.

[0079] On the other hand, when an overhead load is applied to the upper corrugated sheet 1 due to snow accumulation or other reasons, the insulation fitting 2B deforms, causing the reinforcing member 3 to move downwards, and consequently, the contact portion 30 also moves downwards. This downward movement causes the contact portion 30 to contact the top portions 111 and 121 of the lower corrugated sheet 7. The overhead load applied to the upper corrugated sheet 1 is then transmitted to the insulation fitting 2B, the reinforcing member 3, the lower corrugated sheet 7, and the tight frame 2A. Therefore, in this embodiment, the corrugated sheet roof structure 6 can support the upper corrugated sheet 1 against overhead loads using the insulation fitting 2B, the reinforcing member 3, and the tight frame 2A.

[0080] Furthermore, when the snow melts and the load from above on the upper corrugated plate 1 is removed, the insulation fitting 2B deforms, causing the reinforcing member 3 to move upward, and consequently, the contact portion 30 also moves upward. This upward movement causes the contact portion 30 to separate from the tops 111 and 121 of the lower corrugated plate 7. When the contact portion 30 is separated from the lower corrugated plate 7, even if the upper corrugated plate 1 undergoes thermal expansion and contraction in the front-to-back direction (longitudinal direction), and consequently the insulation fitting 2B moves to tilt in the front-to-back direction, the contact portion 30 is less likely to come into contact with the lower corrugated plate 7, thereby reducing noise.

[0081] (Embodiment 2) As shown in Figure 13, the corrugated metal roof structure 6A according to this embodiment differs from the corrugated metal roof structure 6 according to Embodiment 1 in that it includes a reinforcing member 3A.

[0082] In the following, components similar to those in Embodiment 1 will be denoted by common reference numerals and their descriptions will be omitted as appropriate. The configuration described in Embodiment 2 can be applied in appropriate combination with the configuration described in Embodiment 1.

[0083] In this embodiment, the corrugated metal roof structure 6A is provided with a reinforcing member 3A on the tight frame 2A to which the lower corrugated metal sheet 7 is attached. That is, instead of the tight frame 2A of Embodiment 1, a frame member 5A with a reinforcing member is used. The other configurations are the same as in Embodiment 1.

[0084] The frame member 5A with a reinforcing member has a reinforcing member 3A attached to the tight frame 2A. The reinforcing member 3A has a reinforcing member body 34 that is longer in the vertical direction than the reinforcing member body 34 of the reinforcing member 3 of Embodiment 1.

[0085] The reinforcing member 3A is attached to the top plate portion 21A of the tight frame 2A by a connecting portion 33. Specifically, a crimping portion 50 is formed by the connecting hole 332 of the connecting portion 33 of the reinforcing member 3A and the fixing hole 210A of the top plate portion 21A, and the fixing plate 330 of the connecting portion 33 is fixed to the underside of the top plate portion 21A.

[0086] The reinforcing member 3A is attached in a suspended state below the top plate portion 21A of the tight frame 2A. The contact portion 30 of the reinforcing member 3A is formed to be vertically movable between a state of being separated from and a state of being in contact with the roof base 60, which is member 4 located below the reinforcing member 3A.

[0087] In this embodiment, under normal conditions (when no load is applied from above to the lower corrugated sheet 7), the contact portion 30 of the reinforcing member 3A is spaced apart from the roof base 60, which is the member 4 located below the reinforcing member 3.

[0088] On the other hand, when an upward load is applied to the lower corrugated sheet 7 due to snow accumulation or the like, the tight frame 2A deforms, causing the reinforcing member 3A to move downward, and consequently, the contact portion 30 of the reinforcing member 3A also moves downward. This downward movement causes the contact portion 30 to come into contact with the roof substrate 60. The load applied to the lower corrugated sheet 7 from above is then transmitted to the roof substrate 60 by the reinforcing member 3A. Therefore, in this embodiment, the corrugated sheet roof structure 6A can support the tight frame 2A with the reinforcing member 3A.

[0089] Furthermore, when the snow melts and the load on the lower corrugated sheet 7 is removed, the tight frame 2A deforms, causing the reinforcing member 3A to move upward, and consequently, the contact portion 30 also moves upward. This upward movement causes the contact portion 30 to separate from the roof substrate 60. When the contact portion 30 is separated from the roof substrate 60, even if the lower corrugated sheet 7 undergoes thermal expansion and contraction in the front-to-back direction (longitudinal direction), and the tight frame 2A moves to tilt in the front-to-back direction as a result, the contact portion 30 is less likely to come into contact with the roof substrate 60, thereby reducing noise such as friction noise.

[0090] (Embodiment 3) As shown in Figure 14, the corrugated metal roof structure 6B according to this embodiment differs from the corrugated metal roof structures 6 and 6A according to Embodiment 1 or 2 in the configuration of the single corrugated metal roof.

[0091] In the following, components similar to those in Embodiment 1 or 2 will be denoted by common reference numerals and their descriptions will be omitted as appropriate. The configuration described in Embodiment 3 can be applied in appropriate combination with the configuration described in Embodiment 1 or 2.

[0092] The corrugated metal roof structure 6B of this embodiment is a single-layer corrugated metal roof obtained by removing the corrugated metal sheet 1, the frame member with reinforcing members 5, and the insulation material 133 from the double-layer corrugated metal roof of Embodiment 2. Also, instead of the lower corrugated metal sheet 7 of Embodiment 2, a corrugated metal sheet 1 of the same form is used and attached to the tight frame 2A. A backing material 136 is provided on the lower surface of the corrugated metal sheet 1. The other configurations are the same as in Embodiments 1 and 2.

[0093] (Reference example) As shown in Figure 15, the corrugated metal roof structure 6C in the reference example differs from the corrugated metal roof structures 6 and 6A in the configuration of the single corrugated metal roof in embodiment 1 or 2. Furthermore, the corrugated metal roof structure 6C in the reference example differs from the corrugated metal roof structures 6, 6A, and 6B in the configuration in which the corrugated metal 1 and the tight frame 2A are joined by the hanger 135.

[0094] In the following, components similar to those in Embodiments 1 to 3 will be denoted by common reference numerals, and their descriptions will be omitted as appropriate. The components described in the Reference Examples can be applied in appropriate combination with the components described in Embodiments 1 to 3.

[0095] In the example corrugated metal roof structure 6C, a standard corrugated metal sheet is used as the corrugated metal sheet 1, without the locking parts 113, 114, 123, and 124. Similarly, a standard tight frame 2A is used, without the engaging parts 22A and 23A. Adjacent corrugated metal sheets 1 in the left-right direction are joined by hangers 135.

[0096] (Embodiment 4) As shown in Figure 16, the corrugated metal roof structure 6D according to this embodiment differs from the corrugated metal roof structure 6 according to Embodiment 1 in the configuration of the lower corrugated metal 7 and the tight frame 2A.

[0097] In the following, components similar to those in Embodiment 1 will be denoted by common reference numerals and their descriptions will be omitted as appropriate. The configuration described in Embodiment 4 can be applied in appropriate combination with the configuration described in Embodiment 1.

[0098] In this embodiment, the corrugated metal roof structure 6D uses a standard corrugated metal sheet as the lower corrugated metal sheet 7, which lacks the locking portions 113, 114, 123, and 124. Similarly, the tight frame 2A also uses a standard tight frame without the engaging portions 22A and 23A. Furthermore, adjacent corrugated metal sheets 1 in the left-right direction are joined by hangers 135.
