  Hereinafter, a drainage structure for a daylighting roof according to the present invention will be described with reference to the drawings. However, it should be noted that the present invention is not limited to the embodiments described below, and extends to the invention described in the claims and equivalents thereof.

  It should also be understood that the drawings provided in the disclosure of the present invention are intended to illustrate the present invention and are not intended to show an appropriate scale. Moreover, in each drawing, the same or similar code | symbol is attached | subjected to the component which has the same or similar function. Therefore, a component having the same or similar function as the component described above may not be described again.

  Hereinafter, the drainage structure according to the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing an example of the appearance of a daylighting roof 10 having a drainage structure according to the present invention.

  As shown in FIG. 1, a daylighting roof 10 is arranged on a metal folded plate roof 1 fixed on the haze 2 and 3 of the roof structure. The metal folded-plate roof 1 is arrange | positioned so that it may incline with a predetermined angle from the top part of the roof in the water upper side to a water lower side. Therefore, here, the upper right side in the figure is the water side, and the lower left side in the figure is the water side. The daylighting roof 10 includes two first daylighting members 80 and 81 each having a connection surface connected by a connection member such as a push edge 28, a sealing material, and a water stop packing. The 1st daylighting members 80 and 81 have the same inclination as the metal folding plate roof 1 and the 1st daylighting members 80 and 81 connect the daylighting surface which collects external lights, such as the sunlight of the outdoors of a building, The respective connecting surfaces are arranged so as to be orthogonal to the inclination direction of the metal folded plate roof 1. The first daylighting members 80 and 81 are members that collect outside light such as sunlight outside the building, and are nonflammable members. For example, the first daylighting members 80 and 81 may be netted glass.

  FIG. 2 is a cross-sectional view taken along the line AA ′ of FIG.

  As shown in FIG. 2, one end of the first daylighting member 81 is sandwiched between the corner support 43 and the side cover 45, and the other end is supported so as to be sandwiched between the corner support 44 and the side cover 46. The corner support 43 and the side plate 41 are fixed to the first vertical member 15, and the corner support 44 and the side plate 40 are fixed to the second vertical member 16. Side covers 45 and 46 (see FIG. 14B) are arranged outside the corner supports 43 and 44, respectively, and are arranged so as to cover the side surfaces and the upper surface of the corner supports 43 and 44, respectively.

  Below the connecting portion that connects the first daylighting members 80 and 81, the eaves member 26 is disposed close to the first daylighting member 80 and 81. Both ends of the flange member 26 are fixed to the corner supports 43 and 44 by screws 95 and 96, respectively. The upper surface of the collar member 26 faces the first daylighting member 81 and is parallel to the daylighting surface of the first daylighting member. Further, the bottom surface of the flange member 26 positioned opposite to the upper surface is inclined from one end supported by the corner support 43 to the other end supported by the corner support 44. This inclination is parallel to the inclination of the drainage path of the gutter member 26. Therefore, the intrusion water that has flowed into the drainage path of the gutter member 26 is guided to the corner support 44 by the inclination of the drainage path. Next, the intrusion water drained to the corner support 44 is drained to the outside of the daylighting roof 10 through drain holes (not shown) formed in the corner support 44. Further, the intruding water flows down the corner support 44 along the slope thereof, and the blow-in prevention plate 30 (see FIG. 9) and the underwater cover disposed on the underwater side of the daylighting roof 10. 35 (refer to FIG. 17) is also drained to the outside.

  With reference to FIG. 3, the installation state of the collar member 26 arrange | positioned under the connection surface of the 1st daylighting members 80 and 81 is demonstrated. FIG. 3 is a partial perspective view of the daylighting roof 10 viewed from the direction of arrow B in FIG.

  As shown in FIG. 3, the gutter member 26 has a top surface facing the first daylighting members 80 and 81 and parallel to the inclination direction of the roof, and two bottom surfaces positioned opposite to the top surface. The two drainage channels formed by the bottom surface are inclined along a direction orthogonal to the inclination direction of the roof. More specifically, the two drainage path roofs are inclined from the left hand toward the right hand as viewed from the underwater side. Due to this inclination, the intruding water that has flowed into the drainage path of the gutter member 26 is guided to the corner support 44 disposed on the right hand side of the gutter member 26.

  Referring to FIG. 2 again, the second daylighting members 60, 61 and 62 are further provided below the fence member 26 in order to improve the heat insulation effect of the daylighting roof 10 and prevent the intruding water from falling indoors. Are arranged in order from the water side. In FIG. 2, only the 2nd daylighting member 61 arrange | positioned among these is described.

  The second daylighting member 61 is disposed such that the daylighting surface is inclined in the inclination direction of the drainage path. With such a configuration, intrusion water that has reached the daylighting surface of the second daylighting member 61, such as intrusion water that has overflowed the drainage path of the trough member 26, is similar to the intrusion water that has flowed into the drainage path of the trough member 26. Water is guided to the support 44. Next, the intruding water is drained from the corner support 44 to the outside of the daylighting roof 10.

  The coupling member 24 positioned further below the second daylighting member 61 is a member for coupling the three second daylighting members 60, 61, and 62, as will be described in detail later, and is formed on the corner supports 43 and 44, respectively. Is fitted into the notch. By fitting the coupling member 24 into the notches formed in the corner supports 43 and 44, respectively, it is possible to easily prevent the second daylighting members 60, 61 and 62 from being displaced with respect to the inclination direction of the roof 1.

  4 (a) to FIG. 4 (c), FIG. 5 (a) to FIG. 5 (d), FIG. 6 (a) and FIG. b) will be described in order with reference to FIG.

  4A is a plan view of the eaves member 26, FIG. 4B is a side view of the eaves member 26 viewed from the direction of arrow G, and FIG. FIG. 5A is a CC ′ partial cross-sectional view of FIG. 1, FIG. 5B is a DD ′ partial cross-sectional view of FIG. 1, and FIG. 5C is an EE ′ partial cross-sectional view of FIG. FIG. 5D is a partial cross-sectional view of FF ′ in FIG. FIG. 6A is an exploded perspective view of FIG. 5A, and FIG. 6B is an exploded perspective view of FIG. 5D.

  First, the eaves member 26 will be described. As shown in FIGS. 4A to 4C, the eaves member 26 includes a support portion 26a, a first drainage path 26b disposed on one side in the longitudinal direction of the support portion 26a, and a support portion 26a. And a second drainage path portion 26c having the same slope as the slope of the first drainage path 26b. Holes 26d to 26g are formed in the support portion 26a of the flange member 26. As shown in FIG. 2, the holes 26 d and 26 e are formed so as to fix the flange member 26 to the corner supports 43 and 44 with screws 95 and 96. Further, as shown in FIGS. 5A and 5B, the holes 26f and 26g are formed so as to sandwich the first daylighting members 80 and 81 with bolts 90 and nuts 91 together with the pressing edges 28. The holes 26f and 26g are also formed with protrusions for preventing rotation around the head of the bolt 90.

  Here, referring again to FIG. 2, the support portion 26 a located on the upper surface of the eaves member 26 is disposed in parallel with the first daylighting member 81 on the daylighting roof 10, so that the longitudinal direction of the support portion 26 a is the first daylighting member 81. Parallel to the daylighting surface. Moreover, the 1st drainage channel 26b and the 2nd drainage channel part 26c which are parallel to the bottom face of the gutter member 26 incline with a predetermined angle along a longitudinal direction. For this reason, intrusion water is led to the corner support 44 via the 1st drainage path 26b or the 2nd drainage path part 26c. The introduced intruding water is drained to the outside of the daylighting roof 10 through a hole (not shown) formed in the corner support 44 and between the side cover 46 and the second vertical member 16. In the present embodiment, the inclination angle of the first drainage path 26b and the second drainage path portion 26c is about 1/72. However, the inclination angle of the first drainage path 26b and the second drainage path portion 26c is not limited to this angle, and it is sufficient that the intruding water can be guided to the corner support 44. For example, the range of the inclination angle of the drainage channel is preferably 1/100 to 3/100.

  Referring to FIG. 4 again, the eaves member 26 has protrusions 26h and 26i at the ends of the first drainage path 26b and the second drainage path part 26c on the water guide outlet side. The protrusions 26h and 26i have a function of fixing the second daylighting member 61 that is disposed in the vicinity of the lower side of the flange member 26. As shown in FIG. 2, since the 2nd daylighting member 61 inclines in the same direction as the inclination direction of the 1st drainage path 26b and the 2nd drainage path part 26c, there exists a possibility that the 2nd daylighting member 61 may shift | deviate to an inclination direction. . For this reason, it is necessary to prevent the second daylighting member 61 from being shifted in the inclined direction by the protrusions 26h and 26i.

  Next, with reference to FIGS. 5 (a) and 5 (b) and FIG. 6 (a), a connecting portion for connecting the first daylighting members 80 and 81 will be described. The connecting portion that connects the first daylighting members 80 and 81 includes the pushing edge 28, the flange member 26, the bolt 90 and the nut 91, the packing 100, and the water sealing material 102. As shown in FIG. 5A and FIG. 6A, the first daylighting member 80 and the second daylighting member 81 are arranged so as to be sandwiched between the pushing edge 28 and the collar member 26. Further, the first daylighting member 80 and the second daylighting member 81 are fixed by the push edge 28 and the flange member 26 by a bolt 90-1 and a nut 91-1 disposed above the push edge 28. Further, packings 100a and 100b are disposed between the push edge 28 and the first and second daylighting members 80 and 81, respectively, and the first daylighting member 80 and the second daylighting member 81 and the support portion for the eaves member 26 are provided. The packings 100c and 100d are respectively disposed between 26a. Further, a water stop sealing material 102 is disposed between the connecting surfaces of the first daylighting members 80 and 81 facing each other.

  Thus, in the present embodiment, the support portion 26 a of the eaves member 26 is disposed directly below the water stop sealing material 102. By adopting such a configuration, it is possible to prevent the water-stopping sealing material from flowing out when the water-stopping sealing material 102 that is a non-solid material at the beginning of injection is injected between the first daylighting members 80 and 81. For this reason, in this embodiment, the process of inject | pouring a water stop sealing material becomes easy. Moreover, in this embodiment, the hole for penetrating the bolt 90 is not formed in the drainage path of the dredging member 26 that guides the intruding water, but is formed in the support portion 26a of the dredging member 26 that is not a path for guiding the intruding water. . For this reason, the flow of water flowing through the drainage path is not obstructed by the bolt 90. Furthermore, since the bolt hole is not formed in the drainage path, there is no possibility of water leakage from the hole.

  Next, with reference to FIGS. 5C and 5D and FIG. 6B, the connecting portion of the second daylighting members 60 and 61 will be described. As shown in FIG. 6B, the end portions of the second daylighting members 60 and 61 are each bent vertically and accommodated in the coupling member 24 having a concave shape. Since the end portions of the second daylighting members 60 and 61 are respectively accommodated in the coupling member 24, water does not leak from the coupling portion of the second daylighting members 60 and 61. Further, the coupling member 24 is fitted into a notch formed in the corner support 44. The notch formed in the corner support 44 has a shape and a size with which the coupling member 24 can be fitted. Since this notch is orthogonal to the inclination direction of the roof, the second daylighting members 60 and 61 fitted into the notch are not likely to be shifted in the inclination direction of the roof. In addition, as described above, the second daylighting member 61 is prevented from shifting in the inclination direction of the roof member 26 orthogonal to the inclination direction of the roof by the projections 26h and 26i of the roof member 26. There is no risk of shifting in the inclination direction. For this reason, in the present embodiment, the second daylighting member is not fixed using a fixing tool such as a bolt and a nut, and is only placed on the corner supports 43 and 44, and the inclination direction of the roof. There is no risk of shifting in either the parallel direction or the orthogonal direction, and construction is easy. Further, since bolts and nuts are not used for fixing the second daylighting members 60 and 61, there is no need to form through holes for bolts, so there is no risk of water leaking through the through holes for bolts. .

  5A is compared with FIG. 5B, FIG. 5B shows the first drainage path 26b and the second drainage path 26c of the gutter member 26 in comparison with FIG. 5A. The position is lowered. This is because the drainage path of the gutter member 26 has an inclination. Similarly, the position of the second daylighting member 61 arranged close to the first drainage path 26b and the second drainage path 26c is lower in FIG. 5B than in FIG. 5A.

  Moreover, when FIG.5 (c) is compared with FIG.5 (d), the position of the 2nd daylighting members 60 and 61 will become low according to the inclination of a drainage path. For this reason, the height of the notch which fits the coupling member 24 which accommodates the edge part of the 2nd daylighting members 60 and 61, and the height of the support part of the corner supports 43 and 44 which support the 2nd daylighting members 60 and 61 are obtained. The corner support 43 shown in FIG. 5C and the corner support 44 shown in FIG. 5D are different from each other. Therefore, the corner supports 43 and 44 need to be different members. However, members other than the corner supports 43 and 44 such as the vertical member, the side plate, and the side cover can use the same member at both ends of the second daylighting member. For this reason, in this embodiment, many members other than the corner supports 43 and 44 can be made common.

  As the members of the second daylighting members 60, 61 and 62, a plurality of hollow synthetic resin plates made of polycarbonate resin having a hollow honeycomb structure are employed. By adopting the hollow synthetic resin plate, the second daylighting member can have high rigidity and heat insulation performance, and further can be reduced in weight.

  Hereinafter, the assembly procedure of the daylighting roof 10 will be described in order with reference to FIGS.

  FIG. 7 is a first explanatory view for explaining the assembling procedure of the daylighting roof, and shows a state in which the opening 9 is formed by removing a part of the metal folded plate roof 1.

  As shown in FIG. 11, the corner supports 43 and 44 are disposed on the first longitudinal member 15 and the second longitudinal member 16, respectively. The corner supports 43 and 44 are formed with one or a plurality of drain holes 43a and 44a for draining intruding water to the outside of the daylighting roof 10, respectively. The corner support 43 is fixed to the first vertical member 15 so that the drain hole 43a is located outside the first vertical member 15. This is because the intruding water is drained from the drain hole 43a to the outside of the daylighting roof 10. Similarly, the corner support 44 is fixed to the first vertical member 16 so that the drain hole 44 a is located outside the first vertical member 15.

  The second rear plate 51 is attached to the first vertical frame 15 and the second vertical frame 16 by butyl tape (not shown) and screws (not shown) attached on the first vertical frame 15 and the second vertical frame 16. It fixes so that the upper end surface of a 1st backplate may be covered. The second rear surface 51 covers the water-side end portions of the water-side end portions of the first vertical frame 15 and the second vertical frame 16.

  FIG. 17 is an eleventh explanatory view for explaining the procedure for assembling the daylighting roof, and shows a state in which the underwater cover 35 is attached.

  As shown in FIG. 17, the underwater cover 35 is disposed so as to cover the first daylighting member 81 and the side covers 45 and 46, and is fixed in a U shape disposed on the blowing prevention plate 30 shown in FIG. It is fixed with a tool (not shown). Thereby, the underwater side ends of the first daylighting members 80 and 81 are covered. By adopting such a structure, it can be understood that the underwater portion of the daylighting roof 10 is double protected by the blowing prevention plate 30 and the underwater cover 35.

  In the example of the daylighting roof 10 described above, three hollow synthetic resin plates (for example, 500 mm × 5000 mm) are used as the second daylighting members 60, 61 and 62. However, the number of hollow synthetic resin plates to be used is not limited to three, and two or even more can be used. Similarly, the number of the first daylighting members 80 and 81 made of netted glass or the like is not limited to two, and a larger number can be used. Further, in the example of the daylighting roof 10 described above, the daylighting roof 10 is disposed on the metal folded plate roof 1, but it can be applied to other roof structures.

  Further, in the example of the daylighting roof 10 described above, the first drainage path 26b and the second drainage path portion 26c of the gutter member 26 have a structure that is inclined from one end to the other end at a constant angle. However, the flange member 26 may have other structures. For example, it is good also as a structure which has a hat-shaped cross-sectional shape which has a flange at the both ends of a single drainage channel. In this case, a hole for passing the bolt 90 for sandwiching the first daylighting members 80 and 81 is formed on the drainage path. In addition, the inclination angles of the first drainage path 26b and the second drainage path portion 26c may not be the same. Furthermore, the eaves member may have a structure as shown in FIG.

  FIG. 18A is a plan view of another example of the eaves member 27, and FIG. 18B is a side view corresponding to FIG. 18A. The gutter member 27 is different from the gutter member 26 described above in the shape of the drainage path. That is, the eaves member 27 includes a mountain-shaped first drainage path 27b and a second drainage path 27c that are inclined at a certain angle from both ends of the longitudinal center. When the collar member 27 shown in FIG. 18 is employed as the collar member, the second daylighting member disposed below the collar member 27 has a mountain shape with the central portion at the top like the shape of the bottom surface of the collar member 27. It is preferable to be formed as follows.

  As mentioned above, although the drainage structure of the lighting roof which concerns on this invention has been demonstrated with reference to FIGS. 1-18, the drainage structure of the lighting roof which concerns on this invention is not limited to these specific description. Needless to say, various modifications are possible.

  For example, in this specification, the daylighting surfaces of the first daylighting members 80 and 81 have the same inclination as the inclination of the roof 1, but the daylighting face of the first daylighting member has substantially the same inclination as the inclination of the roof 1. It only has to have. That is, the inclination of the lighting surface of the first lighting member is such that the lighting roof arranged at the opening of the roof does not feel that the lighting roof is arranged at a different inclination from the inclination of the roof, that is, the roof and the lighting roof are integrated. As long as it appears to be inclined to the extent that it does not impair the sense of unity, it may not be completely the same inclination.

  Moreover, in this specification, although the connection surface of the 1st daylighting members 80 and 81 is arrange | positioned so as to be orthogonal to the inclination of the roof 1, the connection surface of the 1st daylighting member is substantially orthogonal to the inclination of the roof 1. What is necessary is just to arrange | position. That is, even if the connection surface of the first lighting member is slightly lowered to the right or to the left when the connection surface is viewed from the lower side in the tilt direction, the drainage path is directed to the right or left along the connection surface. It just needs to be inclined. Thus, even when the connection surface of the first daylighting member is arranged so as to be substantially orthogonal to the inclination of the roof 1, the effect of the present invention is exhibited.

  In the present specification, the drainage path of the gutter member 26 is inclined along a direction orthogonal to the inclination direction of the roof 1, but the drainage path of the eaves member is along a direction substantially orthogonal to the inclination direction of the roof 1. Just tilt. That is, the drainage path of the eaves member has the effect of the present invention as long as the drainage path is formed along the connection surface of the first daylighting member.
