Description

[Technical Field]

[0001] The present invention relates to a roof structure provided on a skylight roof having a plurality of roof surface materials. [Background technology]

[0002] Skylight roofs are used on the roofs of outdoor structures. In a skylight roof, multiple frames are installed to fit the roof shape, and multiple roof surface materials are held by the frames. A known roof structure for such a skylight roof is a skylight frame connection structure in which light-transmitting panels are fitted into the frames to interconnect the multiple frames (see Patent Document 1).

[0003] In the conventional skylight frame connection structure described in Patent Document 1 (see Figures 2 to 4 of Patent Document 1), translucent glass plates are fitted into triangular frames to form panels, and multiple panels are combined to form a skylight. At the top of the skylight, the frames of multiple panels are gathered and arranged adjacent to each other. At these frame gathering points, it is necessary to waterproof the spaces between the frames to protect against rainwater. To address this issue, for example, providing a sealant between the frames ensures waterproofing at the frame gathering points. However, providing a sealant at the frame gathering points in the conventional skylight frame connection structure raises concerns about degradation of the sealant due to ultraviolet rays from sunlight. Furthermore, it is not easy to disconnect the frames, and maintenance of the frame gathering points, including replacing degraded sealant, may be time-consuming.

[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 a skylight roof structure and is installed on a skylight roof. Therefore, the skylight roof has a roof structure, and the roof structure forms part of the skylight roof. The skylight roof is the roof of the skylight structure of a structure and is installed on the roof part of the structure. Furthermore, the skylight roof is installed outdoors and covers the structure.

[0010] FIG. 1 is a plan view showing a skylight roof 1 of this embodiment, and shows a schematic view of the skylight roof 1 installed on a structure and a part of a roof structure 2 of the skylight roof 1 as seen from above. As shown in the figure, the skylight roof 1 and roof structure 2 comprise a plurality of frames 3 installed to match the roof shape of the skylight roof 1, a plurality of frame units 4 consisting of frames 3 combined with each other, and a plurality of roof surface materials 5 held by the frames 3 and frame units 4. The directions of the skylight roof 1 and roof structure 2 are specified by the directions when the skylight roof 1 is installed on the structure.

[0011] The frames 3 are roof frames arranged in a grid pattern, and the frame unit 4 is a roof frame unit formed by assembling a plurality of frames 3 as a unit. The frames 3 are also holding members that hold the roof surface material 5, and are arranged along the edges of the roof surface material 5 to hold the edges of the roof surface material 5. Each frame unit 4 has a plurality of frames 3, and the plurality of frames 3 form an opening 4A. The multiple frames 3 of the frame unit 4 are connected at their ends and assembled into a predetermined shape.

[0012] The frames 3 and frame units 4 are arranged in a group at a grouping point 6. The grouping points 6 for the frames 3 and frame units 4 are provided at multiple locations on the skylight roof 1, and the multiple grouping points 6 are dispersed at intervals from one another. The ends of the multiple frames 3 and the corners of the multiple frame units 4 are each gathered at the grouping points 6 and arranged in a ring shape. In this state, the multiple frame units 4 are installed side by side on the skylight roof 1, and adjacent frame units 4 are combined with each other. The frames 3 of adjacent frame units 4 are adjacent to each other and extend parallel to one another.

[0013] Here, the frame unit 4 has three frames 3 assembled in a triangular shape, and is formed in a triangular shape. The three frames 3 of the frame unit 4 form a triangular opening 4A. The roof surface material 5 is formed in a triangular shape corresponding to the shape of the opening 4A. At the gathering point 6, the corners of the six frame units 4 and the ends of the frames 3 of the six frame units 4 gather together.

[0014] The multiple roof surface materials 5 are plate-shaped surface materials of the skylight roof 1, and are each placed in an opening 4A of a frame unit 4 formed by the frame 3. The roof surface materials 5 are held in the opening 4A by the frame 3 and the frame unit 4, and close the opening 4A. The multiple roof surface materials 5 form the roof surface of the skylight roof 1. The roof surface materials 5 are glass surface materials made of glass, and allow light to pass through the roof surface of the skylight roof 1.

[0015] Fig. 2 is a cross-sectional view of the skylight roof 1 of this embodiment taken along line XX in Fig. 1, showing a portion of the skylight roof 1 including two frames 3. Fig. 3 is a structural diagram showing the surrounding area of ​​the gathering point 6 of the skylight roof 1 of this embodiment, showing a portion of the skylight roof 1 in cross section.

[0016] As shown in the figure, the skylight roof 1 comprises a lattice-shaped base body 10 installed below the frame 3, fasteners 11 fixed to the base body 10, and brackets 12 attached to the frame 3. The base body 10 is the base of the skylight roof 1 and has a steel frame 10A made of steel.

The tension members 22 of the frame bodies 20 of adjacent frames 3 are located in the gap 21 between the frame bodies 20 of adjacent frames 3 and abut against each other to seal the gap 21 in the vertical direction. Gap backup members 26, 27 and gap sealants 28, 29 are provided in the gap 21. The tension members 22, gap backup members 26, 27, and gap sealants 28, 29 extend in the longitudinal direction of the frame 3.

[0020] The gap sealants 28, 29 are sealing materials made of an amorphous sealant, and are formed when the amorphous sealant hardens. The gap backup material 26 and the gap sealant 28 are lower gap backup materials and lower gap sealants that are provided in a portion of the gap 21 below the sealant 22 (below the gap 21), and the gap sealant 28 is disposed overlappingly below the gap backup material 26. The gap sealant 28 is received by the gap backup material 26 and fills the gap 21. The gap sealant 28 comes into close contact with the frame main body 20 of the adjacent frame 3, and closes the gap 21 at its lower part. The gap 21 is sealed at its lower part by the gap sealant 28.

[0021] The gap backup material 27 and the gap sealing material 29 are upper gap backup materials and upper gap sealing materials that are provided in a location above the tight material 22 in the gap 21 (the upper part of the gap 21). Here, two upper and lower gap backup materials 27 and two upper and lower gap sealing materials 29 are provided in the upper part of the gap 21. In the gap 21, the gap backup materials 27 and the gap sealing materials 29 are provided alternately from the bottom to the top and are arranged one on top of the other.

[0022] The lower gap sealing material 29 is received by the lower gap backup material 27 and fills the gap 21. Furthermore, the upper gap backup material 27 is disposed overlapping the lower gap sealing material 29.

The gap sealing material 29 comes into close contact with the frame main body 20 of the adjacent frame 3 and closes the gap 21 at the top. The gap 21 is sealed at the top by the double gap sealing material 29.

[0023] The support portion 23 and receiving member 24 of the frame main body 20 are arranged on the opening 4A side of the frame unit 4 with respect to the protruding wall portion 25, and are positioned below the roof surface material 5. The roof surface material 5 (here, the edge portion of the roof surface material 5) is placed from above on the receiving member 24 of the frame main body 20. The receiving member 24 is sandwiched between the roof surface material 5 and the support portion 23 and receives the roof surface material 5. The frame main body 20 supports the roof surface material 5 below with the support portion 23 via the receiving member 24. In this state, the protruding wall portion 25 is spaced apart from the roof surface material 5 and is positioned to the side of the roof surface material 5. The setting block 13 is sandwiched between the roof surface material 5 and the protruding wall portion 25 and is engaged with the protruding wall portion 25.

[0024] The batten 30 has a locking portion 32 that protrudes downward and a pressing portion 33 that presses down the roof surface material 5. The locking portion 32 is locked to the protruding wall portion 25 of the frame main body 20 and is connected to the protruding wall portion 25. The batten 30 is attached to the protruding wall portion 25 and the frame main body 20 by the locking portion 32. The pressing portion 33 of the batten 30 is positioned above and spaced apart from the roof surface material 5 and presses down the roof surface material 5 via a pressing backup material 34 and a pressing seal material 35. The roof surface material 5 is positioned between the support portion 23 of the frame main body 20 and the pressing portion 33 of the batten 30, and the frame 3 holds the roof surface material 5 between the support portion 23 of the frame main body 20 and the pressing portion 33 of the batten 30.

[0025] The holding seal material 35 is a sealing material made of an amorphous sealant and is formed by the hardening of the amorphous sealant. The holding back-up material 34 and the holding seal material 35 are provided between the holding portion 33 of the edge 30 and the roof surface material 5, are arranged one on top of the other, and are sandwiched between the holding portion 33 and the roof surface material 5. The holding seal material 35 is received by the holding back-up material 34 and filled into the space between the holding portion 33 of the edge 30 and the roof surface material 5. The holding seal material 35 is in close contact with the holding portion 33 and the roof surface material 5, and seals the space between the holding portion 33 of the edge 30 and the roof surface material 5 at the tip of the holding portion 33. The space between the holding portion 33 of the edge 30 and the roof surface material 5 is sealed by the holding seal material 35 at the tip of the holding portion 33.

[0026] A gap backup material 36 and a gap sealant 37 are provided in the gap 31 between the ridges 30 of adjacent frames 3. The gap backup material 36 and the gap sealant 37 extend in the longitudinal direction of the frame 3, and the gap sealant 37 is disposed on top of the gap backup material 36. The gap sealant 37 is a sealing material made of an amorphous sealant, and is formed by the amorphous sealant curing. The gap sealant 37 is received by the gap backup material 36 and fills the gap 31. The gap sealant 37 comes into close contact with the ridges 30 of adjacent frames 3, closing the gap 31 at the top. The gap 31 is sealed at the top by the gap sealant 37.

[0027] The skylight roof 1 and roof structure 2 are provided with an erected member 7 that protrudes upward, and a cover 8 and an attachment 9 that are detachably attached to the erected member 7 (see Figure 3). The erected member 7, cover 8, and attachment 9 are provided at the assembly points 6 of the frames 3 and frame units 4, respectively. The erected member 7 is an upright member that stands upright and is installed in an upright position, extending in the vertical direction. The erected member 7 is also fixed to a base body 10 and protrudes upward from the base body 10. The erected member 7 is a steel column member made of round steel, and is erected on the skylight roof 1 in a state where it protrudes above the roof surface material 5 and frame 3.

[0028] The standing member 7 has a columnar portion 7A fixed to the base body 10 and a male threaded portion 7B located above the columnar portion 7A. The columnar portion 7A is a columnar portion of the standing member 7, and has a circular cross section perpendicular to the longitudinal direction (vertical direction) of the standing member 7. The columnar portion 7A protrudes upward from the base body 10 and extends in the vertical direction. The male threaded portion 7B is a portion of the standing member 7 where the male thread is formed, and is formed on the upper part including the upper end of the standing member 7. The male thread of the male threaded portion 7B is formed on the outer periphery of the male threaded portion 7B and extends spirally in the vertical direction. The male threaded portion 7B protrudes upward from the columnar portion 7A and extends in the vertical direction.

[0029] The cover 8 is detachably attached to the male thread portion 7B of the standing member 7, and protrudes laterally from the standing member 7 around the entire circumference of the standing member 7. The attachment 9 is detachably attached to the male thread portion 7B of the standing member 7 at a position higher than the cover 8, and is disposed above the cover 8. The attachment 9 is an upper attachment attached to the upper part of the standing member 7, and protrudes upward from the standing member 7.

[0030] The standing members 7 are installed (standing) at assembly points 6 where frames 3 and frame units 4 are assembled. At each assembly point 6, the multiple frames 3 (frame units 4) are arranged radially around the standing member 7 (here, cylindrical portions 7A) with gaps 40 formed between them, and are assembled around the standing member 7, each holding a roof surface material 5 (see FIG. 1 ). The gaps 40 are gaps provided between the multiple frames 3 (ends of the frames 3) and the standing members 7 (outer peripheries of the standing members 7), and between the multiple frame units 4 (corners of the frame units 4) and the standing members 7 (outer peripheries of the standing members 7). The gaps 40 are formed in a ring shape around the standing member 7, surrounding the standing member 7. The gaps 40 are surrounded by the multiple frames 3 and are open upward and downward.

[0031] The multiple frames 3 are gathered around the standing member 7 while being spaced apart from the standing member 7, and are arranged in order with the standing member 7 at the center. The cylindrical portion 7A of the standing member 7 is surrounded by the multiple frames 3. The multiple frames 3 are also arranged with gaps (gap portions 40) between them and the standing member 7, and extend radially from the standing member 7 at the center. At each location where two roof surface materials 5 are adjacent to each other, two frames 3 are arranged adjacent to each other. The end of the frame 3 on the standing member 7 side and the corner of the frame unit 4 on the standing member 7 side are arranged facing the outer periphery of the standing member 7 with a gap between them.

[0032] Gap backup materials 41, 42 and gap sealing materials 43, 44 are provided in gaps 40 between the multiple frames 3 and the standing member 7. The gap backup materials 41, 42 and the gap sealing materials 43, 44 are each formed in an annular shape and surround the standing member 7. The gap sealing materials 43, 44 are made of an amorphous sealant and are formed by the hardening of the amorphous sealant. The gap backup materials 41, 42 and the gap sealing materials 43, 44 are provided between the end of the frame 3 on the standing member 7 side and the outer periphery of the standing member 7.

[0033] The gap backup material 41 and the gap seal material 43 are lower gap backup material and lower gap seal material provided below the gap 40, and the gap seal material 43 is placed overlapping below the gap backup material 41. The gap seal material 43 is received by the gap backup material 41 and fills the gap 40. The gap seal material 43 comes into close contact with the multiple frames 3 and the standing members 7, closing the gap 40 at the bottom. The gap 40 is sealed at the bottom by the gap seal material 43.

[0034] The gap backup material 42 and the gap seal material 44 are upper gap backup materials and upper gap seal materials that are provided in the upper part of the gap 40. Here, two upper and lower gap backup materials 42 and two upper and lower gap seal materials 44 are provided in the upper part of the gap 40. In the gap 40, the gap backup materials 42 and the gap seal materials 44 are provided alternately from bottom to top and are arranged one on top of the other.

[0035] The lower gap sealing material 44 is received by the lower gap backup material 42 and fills the gap 40. The upper gap backup material 42 is disposed overlapping the lower gap sealing material 44. The upper gap sealing material 44 is received by the upper gap backup material 42 and fills the gap 40. The gap sealing material 44 comes into close contact with the multiple frames 3 and the standing members 7, closing the gap 40 at the top. The gap 40 is sealed at the top by the double gap sealing material 44.

[0036] The cover 8 is an annular covering member that is disposed above the gap 40 and the gap sealing material 44, and covers the gap 40 and the gap sealing material 44 from above. The cover 8 also has a metal (e.g., steel) coping 50 and an elastically deformable rubber water-stopping member 60. The cover 8, coping 50, and water-stopping member 60 are formed in a disk shape that surrounds the standing member 7, and are disposed concentrically with the standing member 7. In this way, the cover 8 is a disk cover, and the coping 50 is a disk coping.

[0037] The cover 8, coping 50, and water-stopping member 60 are arranged around the standing member 7, and protrude from the standing member 7 beyond a position above the gap 40 and gap sealing material 44 to a position above the plurality of frames 3 and roof surface material 5. The cover 8, coping 50, and water-stopping member 60 are spaced above the gap 40 and gap sealing material 44, and are arranged above the gap 40 and gap sealing material 44. The gap 40 and gap sealing material 44 are shielded from above by the cover 8.

[0038] The coping board 50 is an annular cover body, and is disposed above the frame bodies 20 and roof surface materials 5 of the plurality of frames 3, spaced apart above the frame bodies 20 and roof surface materials 5 of the plurality of frames 3. The coping board 50 also has a cylindrical female thread portion 51 attached to the standing member 7, and a disk-shaped flange portion 52 extending from the female thread portion 51. The female thread of the female thread portion 51 is formed on the inner periphery of the female thread portion 51, and extends spirally in the vertical direction.

[0039] As the head board 50 rotates (rotates in the circumferential direction), the female screw portion 51 of the head board 50 is screwed from the upper end to the lower end into the male screw portion 7B of the standing member 7, and is screwed into the male screw portion 7B. The female screw portion 51 also contacts the upper end surface of the cylindrical portion 7A of the standing member 7, stops at the lower end of the male screw portion 7B, and is removably attached to the male screw portion 7B. In this way, the head board 50 is removably attached to the standing member 7. As the head board 50 rotates, the male screw portion 7B displaces the female screw portion 51 and the head board 50 in the vertical direction due to its screw action.

[0040] The water-stopping member 60 is an annular rain barrier, and is formed by rubber injection molding. The water-stopping member 60 is detachably attached to the capping board 50 (here, the flange 52), is supported by the capping board 50, and covers the capping board 50 from above. The water-stopping member 60 also has a disk-shaped attachment portion 61 attached to the capping board 50, multiple (here, three) annular protrusions 62 located on the underside of the capping board 50, and an annular cover portion 63 protruding laterally from the attachment portion 61. The attachment portion 61 is positioned on top of the capping board 50, and covers the capping board 50 from above.

[0041] The multiple protrusions 62 of the water-stopping member 60 are fin-shaped protrusions (fin portions) that are spaced apart from the standing member 7 and arranged in triplicate around the standing member 7. The protrusions 62 protrude downward from the coping board 50 to seal the area below the coping board 50 and stop water flowing over the skylight roof 1 toward the gathering point 6 of the multiple frames 3. In this way, the protrusions 62 stop water flowing toward the gap 40 and the gap sealing material 44, and seal the area above the gap 40. The protrusions 62 are also wall portions that define the drainage path 64 and are arranged in a ring shape surrounding the standing member 7.

[0042] The batten 30 is positioned up to a position above the frame body 20 and the roof surface material 5. At the end of the frame 3 on the standing member 7 side, end T1 of the batten 30 is positioned farther from the standing member 7 than end T2 of the frame body 20 and end T3 of the roof surface material 5. Therefore, at the location on the standing member 7 side of end T1 of the batten 30, above the frame body 20 and the roof surface material 5, water flows from the upstream side to the downstream side without being blocked by the batten 30.

[0043] However, the protrusion 62 of the water-stopping member 60 is positioned above the frame body 20 and the roof surface material 5, closer to the standing member 7 than the end T1 of the batten 30, to stop the water. Therefore, the water is blocked by the protrusion 62 and flows and drains through the area between the end T1 of the batten 30 and the protrusion 62. In this way, the area between the end T1 of the batten 30 and the protrusion 62, and the area above the roof surface material 5 that is continuous with this area, form a drainage path 64.

[0044] The drainage channel 64 is defined in an annular shape above the gathering point 6 of the multiple frames 3 and is provided across the multiple frames 3. The protrusions 62 of the water-stopping member 60 are located on the inner periphery of the annular drainage channel 64 and define the inner periphery of the annular drainage channel 64. The drainage channel 64 is defined along the protrusions 62 and surrounds the protrusions 62. Water flows over the skylight roof 1 toward the gathering point 6 of the multiple frames 3 and reaches the drainage channel 64. The drainage channel 64 drains the water by directing it downstream.

[0045] The cover portion 63 of the water-stopping member 60 is a fin-shaped protrusion that protrudes laterally from the coping 50 and the mounting portion 61 around the entire circumference of the coping 50 and the mounting portion 61. The cover portion 63 also protrudes from the coping 50 and the mounting portion 61 beyond a position above the drainage path 64 to the ridges 30 of the multiple frames 3, and comes into contact with the upper surface of the ridges 30. The cover portion 63 is positioned above the drainage path 64 over the entire length of the drainage path 64, and covers the drainage path 64 from above.

Figures 6, 10, 13, and 15 are structural diagrams showing the surrounding area of ​​the gathering point 6 of the skylight roof 1 of this embodiment.

[0047] As shown in the figures, when constructing a skylight roof 1, a base body 10 is installed, and standing members 7 are erected on the base body 10 at the gathering points 6 of multiple frames 3 (see Figures 4 to 6). Furthermore, without attaching the battens 30 to the frame bodies 20, the frame bodies 20 of the frames 3 are connected to the base body 10, and the frames 3 of multiple frame units 4 are installed. Next, gap backup materials 26, 27 and gap sealants 28, 29 are provided in the gaps 21 between the frame bodies 20 of adjacent frames 3, and gap backup materials 41, 42 and gap sealants 43, 44 are provided in the gaps 40 between the multiple frames 3 and the standing members 7.

[0048] Next, multiple roof surface materials 5 are placed in the openings 4A of the frame units 4, and the roof surface materials 5 are placed on the frame main body 20 of the frame 3 (see FIGS. 7 to 10). In this state, void backup materials 72, 73 and void sealants 74, 75 are provided in multiple voids 70, 71 that are open upward at the locations on the upright member 7 side of the multiple frames 3. Of the voids 70, 71 (see FIG. 9), one void 70 is located between the roof surface material 5 and the frame main body 20 of the frame 3 (here, the projecting wall portion 25), and the other void 71 is located between the frame main bodies 20 of the adjacent frames 3. One void 70 is provided with one void backup material 72 and one void sealant 74, and the other void 71 is provided with the other void backup material 73 and the other void sealant 75.

[0049] The void backup materials 72, 73 and the void sealing materials 74, 75 are arranged along the edges of the frame body 20 of the frame 3 and the roof surface material 5, and the void sealing materials 74, 75 are arranged on top of the void backup materials 72, 73. The void sealing materials 74, 75 are made of an amorphous sealant and are formed by the hardening of the amorphous sealant. The void sealing materials 74, 75 are received by the void backup materials 72, 73 and fill the voids 70, 71. One of the void sealing materials 74 adheres to the roof surface material 5 and the frame body 20 of the frame 3, closing one of the voids 70 at the top. One of the voids 70 is sealed at the top by one of the void sealing materials 74. The other void sealing material 75 adheres to the frame body 20 of the adjacent frame 3, closing the other void 71 at the top. The other cavity 71 is sealed at the top by the other cavity sealant 75 .

[0050] Next, the battens 30 are attached to each of the frame bodies 20 of the multiple frames 3 (see Figures 11 to 13). In this state, a gap backup material 36 and a gap sealant 37 are provided in the gaps 31 between the battens 30 of adjacent frames 3. Next, the coping board 50 of the cover 8 is attached to the standing member 7. The coping board 50 is spaced away from the battens 30 toward the standing member 7, and is positioned above the frame bodies 20 of the frames 3 and the roof surface material 5.

[0051] Next, the water-stopping member 60 is attached to the coping board 50 (see Figures 14 and 15). The protruding pieces 62 of the water-stopping member 60 protrude downward from the coping board 50 and contact the void sealants 74, 75, the roof surface material 5, and the frame body 20 of the frame 3 from above. The protruding pieces 62 of the water-stopping member 60 define a drainage path 64 above the void sealants 74, 75, the roof surface material 5, and the frame body 20 of the frame 3.

[0052] The void sealants 74, 75 are provided in each of the multiple voids 70, 71 located below the drainage path 64, and seal each of the voids 70, 71. The void sealants 74, 75 are provided in the voids 70, 71 so as to be continuous with the upper surface of the adjacent roof surface material 5 and the upper end surface of the frame main body 20 of the frame 3. The upper surface of the roof surface material 5, the upper end surface of the frame main body 20 of the frame 3, and the upper surfaces of the void sealants 74, 75 are continuous with each other and form the lower surface of the drainage path 64.

[0053] The cover portion 63 of the water-stopping member 60 protrudes from the coping board 50 to the side of the coping board 50 and is positioned above the void sealants 74, 75, the roof surface material 5, and the frame body 20 of the frame 3, which are located below the drainage path 64, to cover the void sealants 74, 75, the roof surface material 5, and the frame body 20 of the frame 3 from above. Water flows to the drainage path 64 below the cover portion 63 and flows over the roof surface material 5, the void sealants 74, 75, and the frame body 20 of the frame 3 toward the gap 40 and the gap sealant 44. The protrusion 62 of the water-stopping member 60 stops the water flowing toward the gap 40 and the gap sealant 44, preventing water from entering the gap 40. In this state, the water is drained by the drainage path 64 and along the drainage path 64.

[0054] In the roof structure 2 of the skylight roof 1 described above, the cover 8 blocks sunlight directed toward the gap sealant 44, preventing the gap sealant 44 from being exposed to sunlight. This prevents the gap sealant 44 from deteriorating due to ultraviolet rays from sunlight. It also reduces the frequency of maintenance required for the gap sealant 44. The gap sealant 44 is provided in the gaps 40 between the multiple frames 3 and the standing members 7, making maintenance of the gaps 40 easy. The cover 8 is detachably attached to the standing members 7. By removing the cover 8 from the standing members 7 or by displacing the cover 8 from its attachment position on the standing members 7, the gathering point 6 of the multiple frames 3 can be easily maintained.

[0055] In this way, the roof structure 2 for the skylight roof 1 can improve maintainability at the gathering point 6 of the frames 3 while suppressing deterioration of the gap sealant 44 provided at the gathering point 6 of the frames 3 of the skylight roof 1. It also makes it easy to replace the roof surface material 5. By reducing the amount of sealant provided at the gathering point 6 of the frames 3, it is possible to reduce substances (e.g., silicone oil) that cause dirt to be generated from the sealant, and reduce adhesion of dirt to the roof surface material 5.

[0056] By attaching and detaching the coping 50 of the cover 8 to and from the standing member 7, the cover 8 can be easily attached and detached to and from the standing member 7. Furthermore, the water-stopping member 60 attached to the coping 50 ensures the water-stopping performance of the gathering point 6 of the multiple frames 3. The water-stopping member 60 can also be supported by the coping 50, allowing the water-stopping member 60 to stably exert its water-stopping performance.

[0057] The protrusions 62 of the water-stopping member 60 can prevent water from entering the gaps 40, improving the water-stopping performance of the gathering points 6 of the frames 3. In addition, water can be smoothly drained along the drainage paths 64 defined by the protrusions 62 of the water-stopping member 60. The water-stopping member 60 is provided with a plurality of protrusions 62, which can reliably prevent water from entering the gaps 40.

[0058] The void sealants 74, 75 prevent water from leaking downward along the drainage path 64, and allow water to be reliably drained along the drainage path 64. Furthermore, the cover portion 63 of the water-stopping member 60 blocks sunlight directed toward the void sealants 74, 75, preventing the void sealants 74, 75 from being exposed to sunlight. This makes it possible to suppress deterioration of the void sealants 74, 75 due to ultraviolet rays from sunlight.

[0059] The female threaded portion 51 of the capping board 50 is threadedly engaged with the male threaded portion 7B of the standing member 7, allowing the capping board 50 to be easily attached to the standing member 7. Furthermore, by rotating the capping board 50, the female threaded portion 51 and the capping board 50 can be displaced up and down, facilitating maintenance of the gathering point 6 of multiple frames 3. When performing maintenance on the gathering point 6 of multiple frames 3, the capping board 50 and cover 8 are removed from the standing member 7, and maintenance of the gathering point 6 is performed. Alternatively, maintenance of the gathering point 6 can be performed without removing the capping board 50 and cover 8 from the standing member 7, with the capping board 50 and cover 8 displaced upward.

[0060] The standing member 7 has a cylindrical portion 7A surrounded by multiple frames 3, and the multiple frames 3 are grouped together around the cornerless cylindrical portion 7A of the standing member 7. Therefore, the multiple frames 3 can be arranged radially in various directions around the cylindrical portion 7A of the standing member 7. Furthermore, the cover 8 is formed in a disk shape that surrounds the standing member 7, and the multiple frames 3 are grouped together and arranged below the cornerless cover 8. Therefore, the multiple frames 3 can be arranged radially below the cover 8 in various directions.

[0061] The number of gathering points 6 of the multiple frames 3 provided on the skylight roof 1 is not particularly limited, and may be one or more depending on the roof shape of the skylight roof 1. Furthermore, the roof surface material 5 is not limited to a glass surface material, and may be a roof surface material other than glass, such as a resin surface material made of synthetic resin, a metal surface material made of metal, a wood surface material, or a concrete surface material made of concrete. An example of a concrete surface material is an extruded cement panel (ECP).

[0062] As mentioned above, the roof structure is A roof structure provided on a skylight roof having a plurality of roof surface materials, An erected member that protrudes upward; a plurality of frames arranged radially around the standing member and surrounding the standing member to hold the roof surface material; a gap sealant provided in a gap between the plurality of frames and the standing member; a cover that is detachably attached to the standing member and disposed above the gap sealing material to cover the gap sealing material; It is a roof structure equipped with. Therefore, it is possible to suppress deterioration of the sealing material provided at the point where multiple frames of the skylight roof converge, while improving maintainability at the point where multiple frames converge.

[0063] The cover has a fascia that is removably attached to the standing member and protrudes from the standing member to a position above the multiple frames, and a water-stopping member that is attached to the fascia and covers the fascia. Therefore, by attaching and detaching the coping board to the standing member, the cover can be easily attached and detached to the standing member. In addition, the waterproofing member attached to the coping board can ensure waterproofing performance at the gathering point of multiple frames.

[0064] The water-stopping member protrudes below the fascia board to stop water from flowing toward the gap, and has a protruding piece that is arranged in a ring shape around the standing member and defines a drainage path that spans the multiple frames. Therefore, the protruding pieces of the water-stopping member prevent water from entering the gaps, improving the water-stopping performance of the area where multiple frames meet. Also, water can be smoothly drained along the drainage path defined by the protruding pieces of the water-stopping member.

[0065] The roof structure includes a void sealant that seals a void located below the drainage path, The water-stopping member has a cover portion that protrudes laterally from the coping board and covers the void sealing material. Therefore, the gap sealant prevents water from leaking downward along the drainage path, ensuring that water is drained along the drainage path. In addition, the cover of the water-stopping member can prevent deterioration of the gap sealant.

[0066] The capping member has a female screw portion that is attached to the standing member, The erection member has a male screw portion to which the female screw portion is threadedly attached, and which displaces the female screw portion in the up-and-down direction as the coping rod rotates. Therefore, the capping board can be easily attached to the erection member by threading the female thread of the capping board into the male thread of the erection member. Also, by rotating the capping board, the female thread and the capping board can be displaced up and down, making it easy to maintain the area where multiple frames meet.

[0067] The standing member has a columnar portion surrounded by the plurality of frames. Therefore, a plurality of frames can be arranged radially in various directions around the cylindrical portion of the standing member.

[0068] The cover is formed in a disk shape surrounding the standing member. Therefore, a plurality of frames can be radially arranged in various directions below the cover. [Explanation of symbols]
