Description

[Technical Field]

[0001] The present invention relates to a roof structure in which a roof body is supported by supports. [Background technology]

[0002] A known roof structure is a roof body provided with roofing materials and a gutter frame. Rainwater is collected in the gutter frame by the roofing material with a water gradient and then drained by the gutter frame. The gutter frame is open at an opening on its end face, and the opening on the end face is closed with a water-stopping material. Another known example of such a roof body is a carport roof that has an end cap backing plate that closes the opening on the end face of the gutter formed in the rear frame, and an end cap that sandwiches the end cap backing plate between the rear frame and the end cap (see Patent Document 1).

[0003] In the conventional roof described in Patent Document 1, the end cap backing plate is joined to the rear frame with screws, and then the end cap is joined to the rear frame with screws. By covering the screws for the end cap backing plate with the end cap, the screws are prevented from being exposed, ensuring the design of the end cap backing plate on the roof. However, in the conventional roof, because the end cap backing plate and the end cap must each be joined to the rear frame with screws, the work of installing the end cap backing plate and the end cap on the roof may be time-consuming, and there is room for improvement from the perspective of further improving the workability of the roof.

[0009] An embodiment of a roof structure of the present invention will be described with reference to the drawings. The roof structure of this embodiment is an outdoor structure equipped with a roof body and installed outside a building. Below, the roof structure of this embodiment will be described using a carport as an example, which is a roof structure installed independently of a building.

[0010] FIG. 1 is a perspective view of a roof structural body 1 of this embodiment as seen obliquely from above, and FIG. 2 is a perspective view of the roof structural body 1 of this embodiment as seen obliquely from below. As shown in the figure, the roof structural body 1 is installed at an installation location G and is freestanding at the installation location G. The roof structural body 1 also includes support columns 2 that serve as supports erected at the installation location G of the roof structural body 1, and a roof body 3 supported by the support columns 2. The lower portions of the multiple support columns 2 are buried in the installation location G, and the support columns 2 are arranged in the vertical direction above the installation location G. The support columns 2 are installed in an upright state at the installation location G and protrude above the installation location G.

[0011] The roof body 3 is a covering body that covers the installation location G of the roof structural body 1, and is attached to multiple support columns 2. The roof body 3 is formed in a rectangular shape and connected to the upper ends of the multiple support columns 2. Here, two support columns 2 are installed at a distance from each other, and the roof body 3 is supported by the two support columns 2. The support columns 2 are arranged spaced apart from each other at one edge of the roof body 3's four edges. One edge of the roof body 3 is attached to two support columns 2, and the two support columns 2 support one edge of the roof body 3. The roof body 3 is supported at one edge by two support columns 2 arranged parallel to each other, and overhangs from the support columns 2.

[0012] Fig. 3 is a side view showing the roof structural body 1 of this embodiment as seen in the direction of arrow X1 in Fig. 1. Fig. 4 is a front view showing the roof structural body 1 of this embodiment as seen in the direction of arrow X2 in Fig. 3. Fig. 5 is a plan view showing the roof structural body 1 of this embodiment as seen in the direction of arrow X3 in Fig. 3. As shown in the figures, the roof body 3 of the roof structural body 1 has beams 4, purlins 10, multiple roofing materials 20, and a roof frame 5. The beams 4, purlins 10, and roofing materials 20 are arranged in this order from top to bottom, and the roof frame 5 surrounds the multiple roofing materials 20. Note that in Figures 1, 2, 4, and 5, only the two roofing materials 20 located at both ends of the multiple roofing materials 20 are labeled with reference numerals, and the roofing materials 20 between the two roofing materials 20 located at both ends are not labeled with reference numerals.

[0013] A beam 4 is connected to each of the multiple pillars 2, and each of the multiple purlins 10 is spanned across the multiple beams 4. The beams 4 are attached to the pillars 2, supported by the pillars 2, and extend from the pillars 2. The beams 4 are arranged in a direction intersecting the longitudinal direction (vertical direction) of the pillars 2, and extend in a direction intersecting the longitudinal direction of the pillars 2. The purlins 10 are arranged in a direction intersecting the longitudinal direction of the beams 4 (here, a direction perpendicular to the longitudinal direction of the beams 4), and extend in a direction intersecting the longitudinal direction of the beams 4. The roofing material 20 is arranged in a direction intersecting the longitudinal direction of the purlins 10 (here, a direction perpendicular to the longitudinal direction of the purlins 10), and extend in a direction intersecting the longitudinal direction of the purlins 10.

[0014] Two beams 4 are installed at a distance from each other, and each of the two purlins 10 is supported by the two beams 4. The two beams 4 extend from the respective supports 2 in a direction intersecting the longitudinal direction of the supports 2 and are arranged parallel to each other. The two purlins 10 are each arranged perpendicular to the beams 4 and are arranged parallel to each other. The multiple roof materials 20 are each arranged perpendicular to the purlins 10 and are arranged parallel to each other. The multiple roof materials 20 are lined up in order in the longitudinal direction of the purlins 10 and are arranged side by side.

[0015] The roofing material 20 is arranged inside the roof frame 5, which has multiple corner portions 5A, 5B, and is surrounded by the roof frame 5. The roof frame 5 is a rectangular frame body that is arranged along the periphery of the multiple roofing materials 20 that are connected to each other. The multiple roofing materials 20 are located below the beams 4 and purlins 10, and are arranged side by side inside the roof frame 5 without any gaps between them. The multiple roofing materials 20 are arranged next to each other inside the roof frame 5, blocking the area inside the roof frame 5. In this state, the multiple roofing materials 20 form the roof surface portion of the roof body 3, and cover the installation position G of the roof structural body 1 above.

[0016] The multiple roofing materials 20 have a water gradient K that guides water from the above-water side to the below-water side, and are inclined relative to the horizontal. The water gradient K of the roofing materials 20 is a downward gradient (downward inclination) that descends from the above-water side to the below-water side, and the roofing materials 20 gradually slope downward relative to the horizontal from the above-water side to the below-water side. The above-water side is the highest part of the water gradient K of the roofing materials 20, and the below-water side is the lowest part of the water gradient K of the roofing materials 20. When the roofing materials 20 receive rainwater, the rainwater is guided from the above-water side to the below-water side of the roofing materials 20 by the water gradient K of the roofing materials 20. As a result, the rainwater flows along the water gradient K of the roofing materials 20 from the above-water side to the below-water side of the roofing materials 20, and flows to the under-water part of the roofing materials 20 (the below-water edge).

[0017] The sides of the roof structure 1, roof body 3, and roof material 20 are sides in a direction perpendicular to the direction from the abovewater side to the belowwater side of the water gradient K of the roof material 20 (the water gradient direction of the roof material 20). Furthermore, in each of the multiple roof materials 20, the longitudinal direction of the roof material 20 is the water gradient direction of the roof material 20, and the roof material 20 extends in the water gradient direction (longitudinal direction). The sides of the roof material 20 are the parts located on the sides of the roof material 20 and extend in the water gradient direction of the roof material 20. The abovewater part of the roof material 20 is the end of the roof material 20 located on the abovewater side (abovewater end), and the underwater part of the roof material 20 is the end of the roof material 20 located on the belowwater side (belowwater end). The abovewater and underwater parts of the roof material 20 are one end and the other end of the roof material 20 in the longitudinal direction, and are located at the ends of the roof material 20 in the longitudinal direction.

[0018] The edge of the roofing material 20 is the edge located on the periphery of multiple roofing materials 20 arranged side by side, and the edge on the roof surface of the roof body 3 consisting of multiple roofing materials 20. The above-water edge of the roofing material 20 is the edge located on the above-water side of the roofing material 20 on the roof surface of the multiple roofing materials 20 and the roof body 3, and is composed of the above-water parts of the multiple roofing materials 20 arranged in parallel. The below-water edge of the roofing material 20 is the edge located on the below-water side of the roofing material 20 on the roof surface of the multiple roofing materials 20 and the roof body 3, and is composed of the below-water parts of the multiple roofing materials 20 arranged in parallel. The side edge of the roofing material 20 is the edge located on the side of the roof surface of the multiple roofing materials 20 and the roof body 3, and is the side of the roofing material 20 located at the end on both ends of the multiple roofing materials 20.

[0019] Here, the front, rear, left and right of the roof structural body 1 are defined based on the protruding direction of the roof body 3 protruding from the support columns 2, and the front of the protruding direction of the roof body 3 is referred to as the front, and the rear of the protruding direction of the roof body 3 (the support column 2 side) is referred to as the rear. Therefore, the tip side (free end side) of the protruding direction of the roof body 3 is the front side, and the end side of the roof body 3 supported by the support columns 2 is the rear side. The front-to-back direction is the direction that is front and rear in the protruding direction of the roof body 3. Furthermore, the direction that is left and right when the roof body 3 is viewed in the protruding direction is the left-right direction, and the sides of the roof structural body 1, roof body 3, and roof material 20 are sides in the left-right direction. The above-water side of the roof material 20 is the front side of the roof material 20, and the below-water side of the roof material 20 is the rear side of the roof material 20. Therefore, the above-water part of the roofing material 20 is the front end (front end) of the roofing material 20, and the above-water edge of the roofing material 20 is the front edge (front edge) of the multiple roofing materials 20. The underwater part of the roofing material 20 is the rear end (rear end) of the roofing material 20, and the below-water edge of the roofing material 20 is the rear edge (rear edge) of the multiple roofing materials 20.

[0020] The roof frame 5 has multiple frame members 30, 40, 50 (above-water frame member 30, below-water frame member 40, and a pair of side frame members 50) and multiple corner portions 5A, 5B (above-water corner portion 5A, below-water corner portion 5B) (see Figure 5). The roof frame 5 surrounds multiple roof materials 20 arranged side by side with multiple frame members 30, 40, 50 adjacent to the edges of the roof materials 20. The roof frame 5 and multiple frame members 30, 40, 50 are arranged along the edges of the roof materials 20 to cover the edges of the roof materials 20. The corner portions 5A, 5B are portions located at the corners of the roof frame 5, and the roof frame 5 is bent at the corner portions 5A, 5B. Here, the roof frame 5 has four corner portions 5A, 5B located at the four corners of the roof frame 5. In addition, the two above-water corner portions 5A are located at two above-water corners on the above-water side of the roof material 20 in the roof frame 5, and the two below-water corner portions 5B are located at two below-water corners on the below-water side of the roof material 20 in the roof frame 5.

[0021] The ends of the multiple frame members 30, 40, 50 are connected to each other at corner portions 5A, 5B and fixed to the roof material 20. The ends of the frame members 30, 40, 50 are the ends on both sides of the frame members 30, 40, 50 in the longitudinal direction. The above-water side frame member 30 is a frame member located on the above-water side of the roof material 20 in the roof frame 5, and is arranged along the above-water side edge of the roof material 20. The below-water side frame member 40 is a frame member located on the below-water side of the roof material 20 in the roof frame 5, and is arranged along the below-water side edge of the roof material 20. The side frame members 50 are frame members located on both sides of the roof frame 5, and are arranged along the side edges of the roof material 20. The above-water side frame member 30 and the below-water side frame member 40 extend in the left-right direction, and the side frame member 50 extends in the front-to-back direction and in the direction of the water gradient of the roof material 20.

[0022] Adjacent frame members 30, 40, 50 of the multiple frame members 30, 40, 50 connect and intersect with each other at corners 5A, 5B. The ends of adjacent frame members 30, 40, 50 connect to form the roof frame 5. Adjacent frame members 30, 40, 50 are the above-water side frame member 30 and the left and right side frame members 50, and the below-water side frame member 40 and the left and right side frame members 50. The above-water side frame member 30 and the side frame member 50 have their ends connected at above-water side corners 5A, and the below-water side frame member 40 and the side frame member 50 have their ends connected at below-water side corners 5B.

[0023] Here, the abovewater side corner portion 5A is a front corner portion located at the front corner on the front side of the roof frame 5, and the belowwater side corner portion 5B is a rear corner portion located at the rear corner on the rear side of the roof frame 5. Furthermore, the abovewater side frame material 30 is a front frame material located at the front part of the roof frame 5, and extends in the left-right direction at the front edge of the roof frame 5. The belowwater side frame material 40 is a rear frame material located at the rear part of the roof frame 5, and extends in the left-right direction at the rear edge of the roof frame 5. The side frame materials 50 are frame materials located on the left and right sides of the roof frame 5, and extend in the front-to-rear direction at the left and right side edges of the roof frame 5.

[0024] Fig. 6 is a cross-sectional view showing the roof structural body 1 of this embodiment taken along line X4-X4 in Fig. 5, with the internal structure of the columns 2 and beams 4 shown by chain lines. Fig. 7 is a cross-sectional view showing the roof structural body 1 of this embodiment taken along line X5-X5 in Fig. 5. Fig. 7 schematically shows the roof structural body 1 with a reduced number of roof materials 20 compared to the number of roof materials 20 shown in Fig. 5. As shown in the figure, the beam 4 is connected to the upper end of the support column 2 by a joint material 60, and projects from the support column 2 upward at an installation location G. The support column 2 and the beam 4 are each formed to have a hollow shape, and the joint material 60 is inserted into the interior of the support column 2 and the interior of the beam 4. The joint material 60 is fixed to each of the support column 2 and the beam 4, and the beam 4 is supported by the support column 2 via the joint material 60.

[0025] The purlins 10 are positioned below the beams 4 and attached to the beams 4, and are arranged vertically between the beams 4 and the roofing material 20. The roofing material 20 is a covering material that covers the installation location G of the roof structural body 1, and is attached to the purlins 10 to form the ceiling portion of the roof structural body 1. The multiple roofing materials 20 are positioned below the purlins 10 and are arranged in parallel below the purlins 10. The roof structural body 1 is equipped with connecting materials 61 attached to the ends of the purlins 10. The end roofing materials 20 located at both ends of the multiple roofing materials 20 are positioned below the ends of the purlins 10 and the connecting materials 61 at each of the ends of the purlins 10 and are attached to the purlins 10 and the connecting materials 61. The connecting materials 61 connect the end roofing materials 20 to the ends of the purlins 10, and the end roofing materials 20 overhang the ends of the purlins 10 below the ends of the purlins 10.

[0026] The roof body 3 of the roof structural body 1 and each part that makes up the roof body 3 (beams 4, purlins 10, roofing materials 20, roof frame 5, connecting materials 61) are positioned above the installation location G of the roof structural body 1. The roof body 3 extends from the supports 2 toward above the installation location G, and the roofing materials 20 located in the ceiling section cover the installation location G from above. The multiple roofing materials 20 are arranged side by side on the underside of the purlin 10 and are held by the purlin 10. The connecting materials 61 extend outward (to the side) from the end of the purlin 10 in the longitudinal direction of the purlin 10. The end roofing materials 20 are positioned below the end of the purlin 10 and the connecting materials 61, and extend laterally relative to the end of the purlin 10 and the connecting materials 61.

[0027] The multiple frame members 30, 40, 50 of the roof frame 5 are each fixed to the adjacent roof members 20 with screws 62, which serve as fasteners. The above-water frame member 30 is fixed to the above-water edge 21 of the adjacent roof member 20 (the above-water portion of the multiple roof members 20) at multiple points along its length (left-right direction), and the below-water frame member 40 is fixed to the below-water edge 22 of the adjacent roof member 20 (the below-water portion of the multiple roof members 20) at multiple points along its length (left-right direction). In addition, the side frame member 50 is fixed to the side edge 23 of the adjacent roof member 20 (the side of the end roof member 20) at multiple points along its length (front-to-back direction). The screws 62 are inserted from above through insertion holes formed in the frame materials 30 , 40 , 50 and attached to screw holes formed in the roof material 20 , thereby fixing the frame materials 30 , 40 , 50 to the roof material 20 .

[0028] FIG. 8 is a plan view showing the roof frame 5 and roof material 20 of the roof structural body 1 of this embodiment, and shows an enlarged view of a portion including one of the underwater corner portions 5B in FIG. As shown in the figure, the roof frame 5 has corner caps 6 provided at each of a plurality of corner portions 5A, 5B of the roof frame 5. The corner caps 6 are corner members arranged at the corner portions 5A, 5B, and are arranged between the end of one frame material 30, 40, 50 connected at the corner portions 5A, 5B and the end of the other frame material 30, 40, 50 (between the ends of adjacent frame materials 30, 40, 50).

[0029] The multiple frame members 30, 40, 50 of the roof frame 5 each have an enclosing portion 41, 51 and a fixing portion 42, 52. Note that while Figure 8 shows the enclosing portion 41 and fixing portion 42 of the below-water frame member 40 and the enclosing portion 51 and fixing portion 52 of the side frame member 50, the above-water frame member 30 has an enclosing portion configured similarly to the enclosing portions 41, 51, and a fixing portion configured similarly to the fixing portions 42, 52.

[0030] The surrounding portions 41, 51 of the frame materials 30, 40, 50 are cover portions that surround the roof materials 20 around the periphery of the multiple roof materials 20 (roof surface portions of the roof body 3), and are arranged to surround the roof materials 20. Furthermore, the surrounding portions 41, 51 of the frame materials 30, 40, 50 extend along the edges 21, 22, 23 of the roof materials 20, respectively, and are arranged in positions that surround the multiple roof materials 20. The surrounding portions 41, 51 of the frame materials 30, 40, 50 are not fixed to the roof materials 20 and corner caps 6 by screws, which are fixing devices, but the ends of the surrounding portions 41, 51 of the frame materials 30, 40, 50 are connected to each other at corner portions 5A, 5B of the roof frame 5 by the corner caps 6.

[0031] In this way, the surrounding portions 41, 51 of the multiple frame materials 30, 40, 50 are connected at their ends via corner caps 6 to surround the roof material 20 (the roof surface portion of the roof body 3). The roof frame 5 surrounds the roof material 20 with the frame materials 30, 40, 50 (surrounding portions 41, 51) and covers the edge portions 21, 22, 23 of the roof material 20 around the multiple roof materials 20. The surrounding portions 41, 51 of the frame materials 30, 40, 50 are arranged along the vertical direction and are exposed around the multiple roof materials 20. The edge portions 21, 22, 23 of the roof material 20 are shielded by the surrounding portions 41, 51 of the frame materials 30, 40, 50.

[0032] The fixing portions 42, 52 of the frame members 30, 40, 50 protrude from the surrounding portions 41, 51 and are fixed to the roof member 20. The fixing portions 42, 52 of the frame members 30, 40, 50 are plate-shaped protrusions that protrude from the surrounding portions 41, 51 toward the roof member 20. The fixing portions 42, 52 of the frame members 30, 40, 50 are placed on the roof member 20 and fixed to the roof member 20 with screws 62. The fixing portion of the abovewater-side frame member 30 is fixed to the abovewater-side edge 21 of the roof member 20, the fixing portion 42 of the belowwater-side frame member 40 is fixed to the belowwater-side edge 22 of the roof member 20, and the fixing portion 52 of the side frame member 50 is fixed to the side edge 23 of the roof member 20. The frame materials 30, 40, 50 are attached and held to the roof material 20 by fixing the fixing portions 42, 52 to the roof material 20.

[0033] The ends of adjacent frame materials 30, 40, 50 are located at corner portions 5A, 5B of the roof frame 5 and are connected to each other via corner caps 6. Corner caps 6 are attached to corner portions 5A, 5B and the ends of frame materials 30, 40, 50, connecting the ends of frame materials 30, 40, 50 at corner portions 5A, 5B. Corner caps 6 are also positioned between the ends of enclosing portions 41, 51 of frame materials 30, 40, 50 and attached to the ends of enclosing portions 41, 51 of frame materials 30, 40, 50.

[0034] FIG. 9 is a perspective view of a portion including a below-water corner portion 5B of the roof structural body 1 of this embodiment as viewed obliquely from below, and shows an enlarged view of the portion including one of the below-water corner portions 5B in FIG. As shown in the figure, the roof body 3 has a roof material 20 with a water gradient K, a gutter frame 70 for draining rainwater, and a water-stop material 80 attached to the end of the gutter frame 70. The gutter frame 70 is a gutter material that functions as a gutter for the roof body 3, and is arranged below the underwater edge 22 of the roof material 20. The gutter frame 70 is also located between the underwater ends of a pair of side frame members 50, and is arranged along the underwater edge 22 of the roof material 20. Rainwater flows from the underwater edge 22 of the roof material 20 into the gutter frame 70, and is drained from the roof body 3 by the gutter frame 70.

[0036] As shown in the figure, the roofing material 20 at the end of the multiple roofing materials 20 has a side edge 23 located on its side. The side edge 23 of the roofing material 20 is a protrusion located on the upper side of the roofing material 20, located between the above-water edge 21 and the below-water edge 22 of the roofing material 20, and extends from the above-water edge 21 to the below-water edge 22 of the roofing material 20. The side edge 23 of the roofing material 20 is formed in a curved shape, protruding upward and bending laterally at the upper end. The side edge 23 of the roofing material 20 also serves as a mounting portion (mounting protrusion) on which the frame materials 30, 40, and 50 are placed. The frame materials 30, 40, and 50 (here, the fixing portions 42 and 52 of the frame materials 30, 40, and 50) are placed on the side edge 23 of the roofing material 20 and fixed to the side edge 23 of the roofing material 20 with screws 62.

[0037] The gutter frame 70 has an opposing wall portion 71 that faces the roofing material 20, a fixing piece 72 fixed to the underwater frame member 40, a drainage groove portion 73 that opens upward, a holding portion 74 that is held by the roofing material 20, and an opening 75 located on the end face of the gutter frame 70 (see Figure 10C). The opposing wall portion 71 is a protruding wall portion that protrudes upward and is arranged between the underwater edge portion 22 of the roofing material 20 and the underwater frame member 40 (enclosing portion 41). In addition, in the longitudinal direction (front-to-back direction) of the roofing material 20, the opposing wall portion 71 is arranged at a distance from the underwater edge portion 22 of the roofing material 20 and faces the underwater edge 22 of the roofing material 20 with a gap S between them.

[0038] The fixing piece 72 of the gutter frame 70 is a protrusion connected to the upper end of the opposing wall portion 71, and protrudes from the opposing wall portion 71 toward the underwater edge 22 of the roof material 20. The fixing piece 72 is located below the fixing portion 42 of the underwater frame material 40, abuts against the fixing portion 42, and is fixed to the fixing portion 42 by a fastener, a screw 63. The screw 63 is inserted from above through an insertion hole formed in the fixing portion 42 and attached to a screw hole formed in the fixing piece 72. In this state, the screw 63 is located between the underwater edge 22 of the roof material 20 and the opposing wall portion 71, and is arranged above the gap S. The fixing piece 72 and the gutter frame 70 are fixed to the fixing portion 42 and the underwater frame material 40 by the screw 63, and are held by the fixing portion 42 and the underwater frame material 40. In addition, the opposing wall portion 71 is fixed to the fixed portion 42 and the underwater frame member 40 via the fixing piece 72 and is held by the fixed portion 42 and the underwater frame member 40.

[0039] The drain groove portion 73 of the gutter frame 70 is a water receiving portion (gutter portion) that receives rainwater, and is formed in a concave shape and extends in the longitudinal direction (left-right direction) of the gutter frame 70. The drain groove portion 73 is disposed from the opposing wall portion 71, over the lower part of the gap S, to the lower side of the below-water edge 22 of the roof material 20, and receives water (rainwater) that flows in from the gap S. The gap S is located between the opposing wall portion 71 and the below-water edge 22 of the roof material 20, and above the drain groove portion 73, and is open toward the drain groove portion 73. The portion of the roof material 20 including the below-water edge 22 is located above the drain groove portion 73 and covers it.

[0040] The drain groove portion 73 of the gutter frame 70 is located below the gap S and the roof material 20 (underwater edge portion 22), and is open toward the gap S above between the opposing wall portion 71 and the underwater edge portion 22 of the roof material 20, and is blocked below the roof material 20 by the roof material 20 above. Rainwater flows from above the roof material 20 through the gap S to the inside of the gutter frame 70 (drain groove portion 73). The gutter frame 70 receives rainwater through the drain groove portion 73 and drains it toward the outside of the roof body 3.

[0041] The retaining portion 74 of the gutter frame 70 is a protrusion (retaining piece) that connects to the drainage groove portion 73 and is located above the drainage groove portion 73, spaced apart from the opposing wall portion 71 and the fixing piece 72 on the above-water side of the roofing material 20. The retaining portion 74 is located below the roofing material 20 and abuts against the roofing material 20, and is fixed to the roofing material 20 by a screw 64, which is a fixing device. The screw 64 is inserted from above through an insertion hole formed in the roofing material 20 and attached to a screw hole formed in the retaining portion 74. In this state, the screw 64 is disposed from the top of the roofing material 20 to the drainage groove portion 73. The retaining portion 74 and the gutter frame 70 are fixed to the roofing material 20 by the screw 64 and are held to the roofing material 20. The drainage groove portion 73 is also fixed to the roofing material 20 via the retaining portion 74 and is held to the roofing material 20.

[0042] The underwater frame member 40 of the roof frame 5 is positioned adjacent to the gutter frame 70 and extends along it. The fixing portions 42 of the underwater frame member 40 are fixed to the underwater edge 22 of the roof material 20 with screws 62 at multiple locations along the length of the underwater frame member 40. Furthermore, the fixing pieces 72 of the gutter frame 70 are fixed to the underwater frame member 40 (fixing portions 42) with screws 63 at multiple locations along the length of the gutter frame 70, and the retaining portions 74 of the gutter frame 70 are fixed and held to the roof material 20 with screws 64. The gutter frame 70 is held to the roof material 20 by the retaining portions 74, and is attached to the roof material 20 by being connected to the underwater edge 22 of the roof material 20 via the underwater frame member 40. The underwater frame material 40 covers and shields the opposing wall portion 71 and the upper portion of the gutter frame 70 with the surrounding portion 41, and covers and shields the portion (fixing piece 72) of the gutter frame 70 located between the surrounding portion 41 of the underwater frame material 40 and the underwater edge portion 22 of the roof material 20 with the fixing portion 42.

[0043] The drain groove portion 73, gap S, and gutter frame 70 open at both longitudinal end faces of the gutter frame 70 and are open toward the outside of the gutter frame 70. Openings 75 at the end faces of the gutter frame 70 include the opening of the drain groove portion 73 and the opening of the gap S at the end faces of the gutter frame 70, and are provided at both longitudinal end faces of the gutter frame 70. At the end faces of the gutter frame 70, opening 75, which is the opening of the drain groove portion 73, is located below the roof material 20 (here, the belowwater end of the side edge portion 23 of the roof material 20), and opening 75, which is the opening of the gap S, is located between the opposing wall portion 71 and the belowwater edge portion 22 of the roof material 20.

[0044] The water stop material 80 is a water stop plate formed in a plate shape, and is fixed to the roofing material 20 by screws 65, which serve as fasteners, to close the openings 75 on the end faces of the gutter frame 70. The water stop material 80 is attached to the end faces of the gutter frame 70 on both longitudinal end faces of the gutter frame 70, and covers the end faces of the gutter frame 70, the openings 75, the gaps S, the drain groove portions 73, and the roofing material 20 from the sides. In this state, the water stop material 80 is fixed to the roofing material 20 by screws 65 at multiple locations spaced apart in the longitudinal direction of the roofing material 20. The water stop material 80 adheres closely to the end faces of the gutter frame 70 and the roofing material 20, and stops water from entering the areas between the water stop material 80 and the end faces of the gutter frame 70, and between the water stop material 80 and the roofing material 20.

[0045] Here, the water-stopping material 80 is fixed to the side edge portion 23 of the roofing material 20 by three screws 65, and is fixed to the gutter frame 70 by one screw 65. The three screws 65 are each inserted from the side through insertion holes 81 formed in the water-stopping material 80 and attached to a screw hole 24 formed in the roofing material 20 (side edge portion 23). Furthermore, one screw 65 is inserted from the side through insertion hole 81 formed in the water-stopping material 80 and attached to a screw hole of a screw hole portion 76 formed in the gutter frame 70 (opposing wall portion 71). In this way, the water-stopping material 80 is fixed to the roofing material 20 (side edge portion 23) and the gutter frame 70 (opposing wall portion 71) by the multiple screws 65, and closes the opening of the gap S at the end face of the gutter frame 70 and the opening of the drain groove portion 73.

[0046] The water-stopping material 80 has a fixing plate 82 that is fixed to the roofing material 20 with screws 65, and a gasket 83 that is sandwiched between the fixing plate 82 and the end face of the gutter frame 70. The fixing plate 82 is a metal plate, and is pressed against the end face of the gutter frame 70 and the roofing material 20 (side edge portion 23) with the screws 65. The gasket 83 is an elastically deformable sealing material that is attached to the fixing plate 82. For example, the gasket 83 is a foam material such as sponge, and is attached by bonding to the fixing plate 82. The gasket 83 is sandwiched and compressed between the fixing plate 82 and the end face of the gutter frame 70, and between the fixing plate 82 and the roofing material 20. In this state, the gasket 83 elastically deforms between the fixed plate 82 and the end face of the gutter frame 70, and between the fixed plate 82 and the roof material 20, and adheres closely to the end face of the gutter frame 70 and the roof material 20, sealing the area between the fixed plate 82 and the end face of the gutter frame 70 and the area between the fixed plate 82 and the roof material 20 to stop water from entering.

[0047] The side frame materials 50 of the roof frame 5 are arranged along the side edge 23 of the roof material 20, and the surrounding portion 51 covers the screws 65 (heads of the screws 65) used to secure the water-stopping material 80. The side frame materials 50 extend along the end roof material 20 and the side edge 23 of the roof material 20, and are fixed to the side edge 23. The side frame materials 50 are also arranged along the side edge 23 of the roof material 20 from the abovewater edge 21 to the belowwater edge 22 of the roof material 20, and protrude from the belowwater edge 22 of the roof material 20 across the gap S to a location on the side of the opposing wall portion 71 of the gutter frame 70. The side frame material 50 uses the surrounding portion 51 to cover and shield all screws 65, the portion of the water-stopping material 80 fixed by the screws 65, and the upper portion of the water-stopping material 80 from the side, and the fixing portion 52 uses the water-stopping material 80 and the area between the water-stopping material 80 and the roof material 20 from above to cover and shield them.

[0048] As explained above, in the roof structural body 1 of this embodiment, the water-stopping material 80 is fixed to the roof material 20 with the screws 65. Furthermore, the side frame material 50 covers the screws 65 to prevent them from being exposed. This prevents the structure for fixing the water-stopping material 80 and shielding the screws 65 from becoming complicated, and makes it easy to fix the water-stopping material 80 and shield the screws 65. Therefore, it is possible to improve the workability of the roof body 3 while ensuring the design of the area where the water-stopping material 80 is located on the roof body 3.

[0049] Through the gap S between the opposing wall portion 71 of the gutter frame 70 and the underwater edge 22 of the roof material 20, water flowing over the roof material 20 can smoothly flow from the underwater edge 22 of the roof material 20 into the drainage groove portion 73 of the gutter frame 70, ensuring the drainage performance of the roof body 3. The area between the fixing plate 82 of the water-stopping material 80 and the end face of the gutter frame 70 is sealed with a packing 83, and the water-stopping material 80 can stably stop water from flowing through the opening 75 on the end face of the gutter frame 70.

[0050] By fixing the fixing pieces 72 of the gutter frame 70 to the underwater frame member 40 of the roof frame 5, the gutter frame 70 is connected to the underwater edge 22 of the roof material 20 via the underwater frame member 40, making it possible to maintain the position of the gutter frame 70 relative to the underwater edge 22 of the roof material 20. Furthermore, by maintaining the positional relationship between the underwater edge 22 of the roof material 20 and the gutter frame 70, the gutter frame 70 can reliably receive water flowing in from the underwater edge 22 of the roof material 20. The retaining portions 74 of the gutter frame 70 are held by the roof material 20, preventing displacement of the gutter frame 70 relative to the roof material 20 and allowing the gutter frame 70 to be stably installed on the roof body 3.

[0051] The above-water-side frame member 30 is a frame member in the roof frame 5 that is located on the above-water side of the roof material 20, and may be a frame member other than the front frame member of the roof frame 5. Similarly, the below-water-side frame member 40 is a frame member in the roof frame 5 that is located on the below-water side of the roof material 20, and may be a frame member other than the rear frame member of the roof frame 5. The above-water-side frame member 30 and the below-water-side frame member 40 are positioned apart from each other in the water gradient direction of the roof material 20, with the roof material 20 sandwiched between them. The side frame member 50 is a frame member that is positioned along the side edge 23 of the roof material 20, and is positioned between the above-water-side frame member 30 and the below-water-side frame member 40 of the roof frame 5.

[0052] Multiple roofing materials 20 or a single roofing material may be placed inside the roof frame 5. When a single roofing material is placed inside the roof frame 5, the single roofing material is surrounded by the roof frame 5 to cover the inside area of ​​the roof frame 5, and a gutter frame 70 is placed below the underwater edge 22 of one of the roofing materials 20. In addition, a side frame material 50 is placed along the side edge 23 of one of the roofing materials, and an underwater frame material 40 is fixed to the underwater edge 22 of one of the roofing materials 20.

[0053] The roof structural body 1 requires at least one support column 2, one beam 4, and one purlin 10. However, by providing two or more support columns 2, two or more beams 4, and two or more purlins 10, the roof structural body 1 and the roof body 3 can be installed stably. Also, while the example described here uses support columns 2 as the supports supporting the beams 4 and the roof body 3 of the roof structural body 1, the supports of the roof structural body 1 are not limited to support columns 2 and may be other supports (for example, walls). The present invention is not limited to carports, but can also be applied to various roof structures (for example, cycle ports).
