[0011] (Embodiment 1) (1) Overview The gable structure 1 according to this embodiment is a double-folded-plate roof structure for gable roofs, shed roofs, and other roof structures. The gable structure 1 includes a roof underlayment 2, a tether frame 3 fixed to the gable portion 21 of the roof underlayment 2, and a folded-plate roofing material 4 arranged on the tether frame 3 (see FIG. 1). The tether frame 3 includes a first tether frame 3a, a second tether frame 3b arranged on the first tether frame 3a, and fasteners 7. The first tether frame 3a includes a first vertical frame 31a fixed to the gable portion 21, and the first vertical frame 31a has a first screw hole 72a formed by a female screw. The second tether frame 3b includes a second vertical frame 31b facing the first vertical frame 31a, and the second vertical frame has a second screw hole 72b. The fastener 7 is inserted into the first screw hole 72a and the second screw hole 72b, and fastened to the first screw hole 72a, thereby connecting the first vertical frame 31a and the second vertical frame 31b.

[0012] The gable structure 1 according to this embodiment can connect the first vertical frame 31a and the second vertical frame 31b from the outside with fasteners 7, and can easily form the tight frame 3 for the gable of a double folded-plate roof. Therefore, the gable structure 1 according to this embodiment makes it easy to construct a double folded-plate roof.

[0013] (2)Details The gable structure 1 according to this embodiment is a gable structure for a double folded-plate roof. The gable is the end of the roof on the gable side in a gable roof or a shed roof. A folded-plate roof is a roof formed by installing multiple folded-plate roofing materials on a roof substrate. A double folded-plate roof is a roof in which a lower folded-plate roofing material and an upper folded-plate roofing material are arranged opposite each other with a predetermined gap between them. An insulating material such as rock wool or glass wool may be arranged between the lower folded-plate roofing material and the upper folded-plate roofing material.

[0014] As shown in FIG. 1, the gable structure 1 includes a roof underlayment 2, a tight frame 3, a folded-plate roofing material 4, a clamp 5, a fixing device 6, and a fastener 7.

[0015] <Roofing underlayment> The roof underlayment 2 serves as a base for installing the folded-plate roofing material 4. The roof underlayment 2 includes beams (gable beams) 22 and purlins 23. The beams 22 are components attached to the outer periphery (gable side) of the folded-plate roof. The roof underlayment 2 has a pair of beams 22, each of which is arranged on the gable side of the folded-plate roof. The purlins 23 are components extending in a direction perpendicular to the beams 22. The longitudinal ends of the purlins 23 are placed on and fixed to the beams 22. The roof underlayment 2 includes multiple purlins 23, each of which is arranged so as to span both beams 22. The multiple purlins 23 are arranged at predetermined intervals in the direction of water flow on the folded-plate roof. For the beams 22 and purlins 23, for example, C-shaped steel or the like is used.

[0016] In the drawing, arrow X indicates the direction in which purlins 23 extend (longitudinal direction), which is sometimes called the lateral direction. Arrow Y indicates the direction in which beams 22 extend (longitudinal direction), which is a direction perpendicular to arrow X. Arrow Z indicates the upward direction, which is a direction perpendicular to both the directions of arrows X and Y.

[0017] <Tight frame> The tight frame 3 is a member that fixes the folded-plate roof material 4 to the roof underlayment 2. In this embodiment, the tight frame 3 is for a gable. The tight frame 3 for a gable is fixed to the gable portion 21 of the roof underlayment 2. Specifically, the tight frame 3 is placed on and fixed to the upper surface of the purlin 23 in the gable portion 21.

[0018] As shown in Fig. 2, the tight frame 3 includes a vertical frame 31, a horizontal frame 32, and an inclined frame 33. The tight frame 3 is formed by processing a long, thin strip-shaped metal plate (for example, a steel plate) by bending, cutting, or the like.

[0019] The vertical frame 31 is a part that protrudes upward (in the direction of arrow Z) from the purlin 23 of the roof foundation 2 when the tight frame 3 is fixed to the roof foundation 2. A fixing part 35 is provided at the lower end of the vertical frame 31.

[0020] The horizontal frames 32 are parts that protrude horizontally from the vertical frames 31. That is, the horizontal frames 32 are provided at the upper ends of the vertical frames 31, and are formed so as to protrude in the direction of arrow X (towards the interior) when viewed from the vertical frames 31 when the tight frame 3 is fixed to the roof underlayment 2. The horizontal frames 32 also have slits 37 formed therein. The slits 37 are formed near the boundary between the vertical frames 31 and the horizontal frames 32. The slits 37 are formed long in the direction of arrow Y.

[0021] The inclined frame 33 is a portion that protrudes obliquely downward from the horizontal frame 32. That is, the inclined frame 33 is provided at the end of the horizontal frame 32 (the end opposite the end on the vertical frame 31 side), and is formed so as to protrude obliquely downward as seen from the horizontal frame 32 when the tight frame 3 is fixed to the roof underlayment 2. A fixing portion 36 is provided at the lower end of the inclined frame 33.

[0022] The inclined frame 33 is provided with a locking portion 34. The locking portion 34 is formed by cutting and raising a portion of the inclined frame 33 on the surface side. The locking portion 34 is formed in a claw shape that protrudes from the surface of the inclined frame 33. The inclined frame 33 has two locking portions 34. One of the locking portions 34 is formed as a first locking portion 341, and the first locking portion 341 is located above the center of the inclined frame 33 in the inclined direction. The other locking portion 34 is formed as a second locking portion 342, and the second locking portion 342 is located below the center of the inclined frame 33 in the inclined direction.

[0023] As shown in FIGS. 1 and 5, this embodiment includes a first tight frame 3a and a second tight frame 3b as the tight frame 3.

[0024] The first tight frame 3a is formed similarly to that shown in FIG. 2 and includes a first vertical frame 31a, a horizontal frame 32, and an inclined frame 33. The second tight frame 3b is formed similarly to that shown in FIG. 2 and includes a second vertical frame 31b, a horizontal frame 32, and an inclined frame 33, but the second vertical frame 31b does not have a fastening portion 35. The second vertical frame 31b also has a rib 311. The rib 311 extends over substantially the entire length of the second vertical frame 31b in the vertical direction (the direction of arrow Z) and protrudes outward from the second vertical frame 31b (in the direction opposite to the direction toward the inclined frame 33 of the second tight frame 3b). The inclined frame 33 of the second tight frame 3b also does not have a fastening portion 36. Instead, it has an engagement portion 38.

[0025] <Folded plate roofing material> The folded-plate roofing material 4 is a component that constitutes a folded-plate roof. As shown in Fig. 3, the folded-plate roofing material 4 is 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 long so as to extend along the slope direction of the roof (the direction of water flow). The folded-plate roofing material 4 is formed with a substantially U-shaped cross section, and is formed with a valley portion 40 and inclined pieces 41 that protrude diagonally upward from both side ends of the valley portion 40.

[0026] One of the inclined piece portions 41 is composed of an inclined portion 42 that protrudes diagonally upward and outward from one side end of the valley portion 40 (the opposite side to the valley portion 40), an apex 43 that protrudes approximately horizontally from the upper end of the inclined portion 42 toward the outside (the opposite side to the valley portion 40), and an engaging portion 44 that has an approximately inverted U-shaped cross section and protrudes upward from the end of the apex 43.

[0027] The other inclined piece portion 41 is composed of an inclined portion 42 that protrudes diagonally upward and outward from one side end of the valley portion 40 (the opposite side to the valley portion 40), an apex portion 43 that protrudes approximately horizontally from the upper end of the inclined portion 42 toward the outside (the opposite side to the valley portion 40), and an engaging portion 45 that has an approximately inverted L-shaped cross section and protrudes upward from the end of the apex 43.

[0028] The inclined portion 42 of each inclined piece portion 41 is provided with a locking step 441. The locking step 441 is formed by bending a part of the inclined portion 42 in the thickness direction so as to form a step. Each locking step 441 has a first locking step 4111 and a second locking step 4112. The first locking step 4111 is formed above the center of the inclination direction of the inclined portion 42. The second locking step 4112 is formed below the center of the inclination direction of the inclined portion 42. The first locking step 4111 and the second locking step 4112 are formed over the entire length of the folded-plate roofing material 4 in the longitudinal direction.

[0029] In this embodiment, as the folded-plate roofing material 4, a first folded-plate roofing material 4a and a second folded-plate roofing material 4b are used.

[0030] <Clamp> The clamp 5 is a member that presses and fixes the folded plate roof material 4 to the tight frame 3, and can be made of a metal member (metal fitting). As shown in Figure 4, the clamp 5 has an attachment portion 51 and a fixing piece 52.

[0031] The mounting portion 51 is attached to the tight frame 3 and includes an insertion piece 511, a support piece 512, an opposing piece 513, and an extension piece 514. The insertion piece 511 and the opposing piece 513 face each other in the horizontal direction with a predetermined gap between them. The upper end of the insertion piece 511 and the upper end of the opposing piece 513 are connected by the support piece 512. A protruding insertion portion 54 is provided at the lower end of the insertion piece 511. The insertion portion 54 is inclined outward from the lower end of the insertion piece 511 (the side opposite the opposing piece 513). The insertion portion 54 is bent at an angle of approximately 20° relative to the in-plane direction of the flat outer surface of the insertion piece 511 (the surface not facing the opposing piece 513). A protruding extension piece 514 is provided at the lower end of the opposing piece 513. The extension piece 514 protrudes toward the side opposite the insertion piece 511.

[0032] The fixing piece 52 is formed to protrude from the mounting portion 51. The fixing piece 52 is arranged on the folded-plate roofing material 4. In other words, when the clamp 5 is attached to the tight frame 3, the fixing piece 52 is arranged along the upper surface (outer surface) of the folded-plate roofing material 4. The fixing piece 52 has a locking and retaining portion 521. The locking and retaining portion 521 is formed by bending the fixing piece 52 downward from the tip of the fixing piece 52 in the length direction (the direction of protrusion from the mounting portion 51) at approximately a right angle to the fixing piece 52.

[0033] Furthermore, the fixing piece 52 is provided with a hole 53. The hole 53 has a first hole 531 and a second hole 532. The first hole 531 and the second hole 532 are provided in an upper part of the fixing piece 52. The first hole 531 and the second hole 532 are provided side by side in a direction perpendicular to the longitudinal direction of the fixing piece 52. Each hole 53 is formed to penetrate the fixing piece 52 in the thickness direction.

[0034] In this embodiment, the presser 5 includes a first presser 5a and a second presser 5b.

[0035] <Construction method> The formation of the ridge structure 1 according to this embodiment is carried out as follows.

[0036] First, the first tight frame 3a is fixed to the gable portion 21 of the roof underlayment 2 (see Figures 1 and 5). In this case, the fastening portions 35, 36 of the first tight frame 3a are placed on the top surface of the purlin 23 and fixed to the purlin 23 by welding, bolting, screws, etc. The first tight frame 3a is also fixed so that the inclined frame 33 faces inward relative to the vertical frame 31 (toward the center of the roof underlayment 2 in a plan view). The first vertical frame 31a of the first tight frame 3a protrudes upward relative to the roof underlayment 2. The horizontal frame 32 protrudes laterally (inward) from the vertical frame 31. The inclined frame 33 protrudes diagonally downward (inward-downward) from the horizontal frame 32.

[0037] Next, the first folded-plate roofing material 4a is placed above the first tight frame 3a (see Figures 1 and 5). In this case, the top 43 of one of the inclined piece portions 41 of the first folded-plate roofing material 4a is placed on the upper surface of the horizontal frame 32 of the first tight frame 3a, and the fitting portion 44 is located above the horizontal frame 32. In addition, the inclined portion 42 of one of the inclined piece portions 41 of the first folded-plate roofing material 4a is placed along the outer surface (upper surface) of the inclined frame 33. At this time, the locking step 441 of the first folded-plate roofing material 4a is hooked onto the locking portion 34 of the first tight frame 3a. That is, the first locking step 4111 of the first folded-plate roofing material 4a is hooked onto the first locking portion 341 of the first tight frame 3a, and the second locking step 4112 of the first folded-plate roofing material 4a is hooked onto the second locking portion 342 of the first tight frame 3a. When hooking the locking step 441 onto the locking portion 34, the back surface of the locking step 441 is brought into contact with the tip of the locking portion 34. This causes the first folded plate roof material 4a to be hooked onto and fixed to the first tight frame 3a.

[0038] Next, the first clamp 5a is attached to the first tight frame 3a (see Figures 1 and 5). At this time, the insertion portion 54 of the first clamp 5a is inserted into the slit 37 of the first tight frame 3a from above. This positions the mounting portion 51 of the first clamp 5a on the horizontal frame 32 of the first tight frame 3a. The insertion piece 511 of the first clamp 5a is positioned outside the fitting portion 44 of the first folded-plate roofing material 4a (opposite the direction of arrow X). The support piece 512 of the first clamp 5a is positioned above the fitting portion 44 of the first folded-plate roofing material 4a. The opposing piece 513 of the first clamp 5a is positioned inside the fitting portion 44 of the first folded-plate roofing material 4a (in the direction of arrow X). The extension piece 514 of the first clamp 5a is positioned on the top surface of the top 43 of the first folded-plate roofing material 4a.

[0039] Then, the fixing piece 52 of the first retainer 5a is arranged along the upper surface (outer surface) of the inclined portion 42 of the first folded plate roofing material 4a. At this time, the locking holding portion 521 of the fixing piece 52 hooks onto the first locking step 4111 of the first folded plate roofing material 4a. In other words, the back surface of the locking holding portion 521 is brought into contact with the outer surface of the first locking step 4111. As a result, the first locking step 4111 is sandwiched between the tip of the first locking portion 341 and the back surface of the locking holding portion 521, making it difficult for the first folded plate roofing material 4a and the first tight frame 3a to come loose from their engagement.

[0040] Next, the fixing pieces 52 of the first clamping member 5a are fixed to the first tilt frame 3a using multiple fixing devices 6 (see Figures 1 and 5). Fixing devices 6 can be screws, bolts, nails, bolts, etc. The multiple fixing devices 6 are inserted from above into the first hole 531 and the second hole 532, respectively, and penetrate the inclined portion 42 of the inclined piece portion 41 of the first folded-plate roofing material 4a, reaching and connecting to the inclined frame 33 of the first tilt frame 3a. The fixing devices 6 are connected to the first tilt frame 3a near the base (rising portion) of the first locking portion 341. Thus, the multiple fixing devices 6 are spaced apart in a direction perpendicular to the inclination direction of the inclined frame 33. This allows for a stronger connection between the fixing pieces 52 and the inclined frame 33 than when a single fixing device 6 is used. Furthermore, the fixing pieces 52 and the inclined frame 33 can be connected more firmly than when multiple fixing devices 6 are concentrated in one location.

[0041] When the clamp 5 and the folded plate roofing material 4 are joined in this manner, the folded plate roofing material 4 can be firmly attached to the tight frame 3 via the clamp 5. That is, the insertion portion 54 of the clamp 5 is inserted into the slit 37 of the tight frame 3, and the insertion portion 54 is bent slightly outward and inclined in a direction perpendicular to the longitudinal direction of the slit 37 in a plan view. Therefore, when the folded plate roofing material 4 tries to return due to spring back or is lifted by negative pressure, etc., even if the clamp 5 is lifted together with the clamp 5, the insertion portion 54 is less likely to come out of the slit 37, and the connection between the folded plate roofing material 4 and the tight frame 3 is less likely to come loose.

[0042] Next, a closing plate 73 is arranged along the outer surface (the surface facing the outdoors) of the first vertical frame 31a. Like the folded-plate roofing material 4, the closing plate 73 is formed by bending a metal plate such as a painted steel plate, and is formed long so as to extend in the Y direction. The portions of the closing plate 73 extending in the Z and Y directions are sandwiched and fixed between the first vertical frame 31a and the second vertical frame 31b. The portions extending in the X and Y directions are placed on the roof underlayment 2. That is, the closing plate 73 is composed of a placing piece 731 placed on the purlin 23, an upright piece 732 protruding upward from the X-direction end of the placing piece 731, a 733 protruding in the X-direction from the upper end of the upright piece 732, and a locking piece 734 protruding downward from the X-direction end of the cover piece 733. The upright piece 732 is disposed between the first vertical frame 31a and the second vertical frame 31b. The cover piece 733 is disposed above the mounting portion 51 of the presser 5. The locking piece 734 is disposed on the X-direction side of the mounting portion 51.

[0043] Next, the second tight frame 3b is attached to the upper side of the first tight frame 3a. The engaging portion 38 of the second tight frame 3b is hooked onto the outer surface of the second locking step portion 4112 of the first folded-plate roofing material 4a. The second vertical frame 31b of the second tight frame 3b is connected to the first vertical frame 31a of the first tight frame 3a with fasteners 7. At this time, the second vertical frame 31b is arranged along the outer surface of the closing plate 73. The first vertical frame 31a and the second vertical frame 31b face each other via the closing plate 73. Then, fasteners 7 such as bolts are tightened into the first screw holes 72a provided in the first vertical frame 31a and the second screw holes 72b provided in the second vertical frame 31b. At this time, the heads (bolt heads) 71 of the tightened fasteners 7 do not protrude outward beyond the ribs 311 of the second tight frame 3b.

[0044] The fastener 7 penetrates the upright piece 732 of the closing plate 73 in the thickness direction (X direction) between the first vertical frame 31a and the second vertical frame 31b. That is, the first screw hole 72a provided in the first vertical frame 31a and the second screw hole 72b provided in the second vertical frame 31b face each other with the upright piece 732 of the closing plate 73 interposed therebetween.

[0045] Both the first screw hole 72a provided in the first vertical frame 31a and the second screw hole 72b provided in the second vertical frame 31b can be formed with female threads, but the second screw hole 72b provided in the second vertical frame 31b may not be formed with female threads and may simply be a through hole.In this case, the second screw hole 72b in the second vertical frame 31b is formed as a through hole of a size that allows the body of a fastener 7 such as a bolt to pass through but not the head 71 to pass through.

[0046] In this way, after the second tight frame 3b is attached to the upper side of the first tight frame 3a, the second corrugated plate roofing material 4b, the second clamp 5b, and the fixing device 6 are installed on the second tight frame 3b in the same manner as in the case of the first corrugated plate roofing material 4a (see Figures 1 and 5).

[0047] Next, the gable wrap 8 is placed (see Figures 1 and 5). The gable wrap 8 is formed by bending a metal plate similar to that of the folded-plate roofing material 4. The gable wrap 8 has an exterior wall covering portion 81 that is placed on the upper outer side (outdoor side) of the exterior wall material 9. The exterior wall covering portion 81 is fixed to the beams 22 of the roof underlayment 2 with fasteners 80 such as screws. The gable wrap 8 also has an outer periphery 82. The outer periphery 82 is formed to protrude upward from the exterior wall covering portion 81. The outer periphery 82 is located outside (outdoor side) the tight frames 3 (first tight frames 3a and second tight frames 3b). Between the vertical frames 31 of the tight frames 3 and the outer periphery 82, mounting members 83 are provided on the purlins 23, and the outer periphery 82 is fixed to the mounting members 83 with fasteners 84 such as screws. The gable wrap 8 also has an upper surface portion 85. The upper surface portion 85 is provided so as to protrude inward from the upper end of the outer peripheral portion 82. The upper surface portion 85 is placed on the support piece 512 of the presser 5 and is fixed with a fixing device 86 such as a screw.

[0048] As shown in FIG. 1, the gable wrap 8 has a folded plate covering portion 87. The folded plate covering portion 87 is formed by protruding diagonally downward and inward from the upper surface portion 85. The folded plate covering portion 87 is positioned opposite the inclined piece portion 41 of the second folded plate roofing material 4b. A folded portion 88 is provided at the tip of the folded plate covering portion 87, and the folded portion 88 is hooked onto a locking member 89. The locking member 89 is attached to the outer surface of the second folded plate roofing material 4b below the fixing piece 52 with a fixing device 90 such as a screw.

[0049] In the gable structure 1 according to this embodiment as shown in FIG. 1, the folded-plate roofing materials 4 (first folded-plate roofing materials 4a and second folded-plate roofing materials 4b) are fixed to the tight frames 3 in a state sandwiched between the fixing pieces 52 connected by the fasteners 6 and the tight frames 3 (first tight frames 3a and second tight frames 3b), improving the fixing strength of the folded-plate roofing materials 4 to the tight frames 3. In addition, the fasteners 7 can be tightened from the outer periphery of the gable portion 21, making it easier to connect the first tight frames 3a and the second tight frames 3b and facilitating construction. In addition, the closing plate 73 can be fixed at the same time as tightening the fasteners 7, making construction easier.

[0050] (Embodiment 2) The gable structure 1 according to this embodiment differs from the gable structure 1 according to embodiment 1 in the configuration of the tight frame 3, folded plate roof material 4, and clamp 5. Hereinafter, the same configuration as embodiment 1 will be assigned the same reference numerals and explanations will be omitted as appropriate. The configuration described in embodiment 2 can be applied in appropriate combination with the configuration described in embodiment 1.

[0051] In this embodiment, the tight frame 3 includes a first tight frame 3a and a second tight frame 3b, as in embodiment 1. The first tight frame 3a is formed similarly to the first tight frame 3a in embodiment 1. The second tight frame 3b is formed similarly to the second tight frame 3b in embodiment 1, but differs in that the inclined frame 33 does not have a locking portion 34. In other words, the upper surface of the inclined frame 33 is formed substantially flat.

[0052] In this embodiment, the second folded-plate roofing material 4b has a valley portion 40 and an inclined piece portion 41, similar to the second folded-plate roofing material 4b of embodiment 1, but the inclined piece portion 41 does not have a locking step portion 441. In other words, the inclined piece portion 41 is formed almost flat.
