Description

Technical Field

[0001] The present disclosure relates to an eaves gutter end stop member and a rainwater drainage structure.

Background Art

[0002] Conventionally, there is known a drainage structure that collects rainwater falling on the roof of a building with an eaves gutter provided at the eaves edge, sends the collected rainwater to a downspout, and guides the rainwater to the vicinity of the ground through the downspout, so that the rainwater does not drip from the eaves edge.

[0003] Patent Document 1 discloses a gutter connecting member that connects an eaves gutter and a downspout to an end portion of the eaves gutter in the extending direction. The gutter connecting member is provided with a downspout connection hole portion connected to the downspout, so that there is no need to form an opening in the eaves gutter, and the rainwater collected in the eaves gutter can flow from the gutter connecting member to the downspout.

Summary of the Invention

Problem to be Solved by the Invention

[0005] In the configuration of Patent Document 1, it is conceivable to install a flexible drain in order to suppress the influence of dust such as fallen leaves and efficiently drain rainwater. A flexible drain generally includes a water collecting cylinder having an upper flange and a drain cylinder having a lower flange. When installing the flexible drain, the water collecting cylinder is penetrated from above the opening provided in the bottom plate of the eaves gutter, the upper flange is locked to the peripheral edge of the opening, and the drain cylinder is screwed onto the water collecting cylinder penetrating below the opening, and the lower flange of the drain cylinder is locked to the peripheral edge of the opening, so that the water collecting cylinder and the drain cylinder are integrated and attached to the eaves gutter.

[0006] In the configuration disclosed in Patent Document 1, when a flexible drain is installed on the gutter connecting member, the thickness of the upper flange creates a step between the bottom wall of the gutter connecting member and the upper flange, leaving room for improvement in terms of efficiently draining rainwater. Furthermore, in the gutter connecting member disclosed in Patent Document 1, the positional relationship between the downpipe connection part and the exterior wall depends on the position of the downpipe connection hole, so the downpipe may be installed far away from the vicinity of the building's exterior corner. In this case, the appearance of the building deteriorates, and the construction work of fixing the downpipe bracing to the column located on the inside near the building's exterior corner becomes difficult. For these reasons, there is a need for a gutter end member that can efficiently guide rainwater into the downpipe when a drain with an upper flange is attached, while also improving the building's appearance and ease of installation. [Means for solving the problem]

[0007] The gutter stopper member according to this disclosure is attached to one end of the gutter in the longitudinal direction and comprises a bottom plate, a rear wall rising from the bottom plate and positioned on the exterior wall side of the building, a front wall rising from the bottom plate and positioned on the opposite side of the exterior wall, and a side wall rising from the bottom plate and positioned at the end opposite to the gutter. The bottom plate has a through hole for attaching a drain, and the upper surface of the bottom plate includes a counterbore radially outward from the periphery of the through hole for engaging the upper flange of the drain, and the center of the through hole is positioned on the rear wall side of the midpoint between the lower inner ends of the front wall and the rear wall, and is positioned on the side wall side of the midpoint between the lower inner end of the side wall and the gutter side edge.

[0008] The rainwater drainage structure according to this disclosure is characterized by comprising a gutter, a gutter end member attached to one end of the gutter in the longitudinal direction, and a drain. [Effects of the Invention]

[0009] According to the gutter stopper member and rainwater drainage structure described herein, when a drain having an upper flange is installed, rainwater can be efficiently guided to the downpipe, and the downpipe can be installed close to the exterior corners of the building while improving ease of installation, thereby improving the appearance of the building.

[Figure 6] This is a schematic diagram showing the installation of a downpipe near an external corner of a building. [Modes for carrying out the invention]

[0011] Hereinafter, an example of an embodiment of the gutter end member according to this disclosure will be described in detail with reference to the drawings. The shapes, numbers, materials, etc. described below are illustrative examples for illustrative purposes and can be appropriately modified depending on the specifications of the gutter end member and the rainwater drainage structure including the gutter end member. The embodiments described below are merely examples, and this disclosure is not limited to these embodiments. Furthermore, forms obtained by selectively combining the various components of the multiple embodiments and modifications described below are included in this disclosure.

[0012] Figure 1 is a perspective view showing a part of a building 100 in which a rainwater drainage structure 80, including a gutter end member 10 which is an example of an embodiment, is installed. In the building 100 in which the rainwater drainage structure 80 is installed, a gutter 81 is attached to the eaves of the roof 101. Figure 2 is a perspective view of the gutter end member 10, which is an example of an embodiment, as seen from the gutter connection side. As shown in Figure 1, the rainwater drainage structure 80 comprises a gutter 81, a gutter end member 10 attached to one end of the gutter 81 in the longitudinal direction, a drain 20 (see Figures 4 and 5), which is a flexible drain attached to the gutter end member 10, and a downpipe 85 connected to the gutter 81 via the drain 20, and is installed in the building 100. The gutter 81 has a grooved cross-section with an open top surface, where the lower ends of the front wall 82 and rear wall 83, which are separated in the front-rear direction, are connected by a bottom plate 84, and it extends in the left-right direction. Here, "left-right direction" refers to the left-right direction when viewed from the front side facing the exterior wall surface 75 to which the downpipe 85 is attached. The front side is the front side, and the rear side is the exterior wall surface 75 side. "Front-back direction" refers to the direction connecting the front side and the exterior wall surface 75 side.

[0013] The gutter 81 comprises a main body 81a formed by extruding a synthetic resin such as polyvinyl chloride resin, and a stopper member 86 fixed to the end of the main body 81a. The gutter 81 is suspended by a hanger (not shown) attached to the building and is designed to receive rainwater that falls on the roof 101.

[0014] The gutter 81 has a gutter end member 10, detailed in Figure 2, attached to one end of the main body 81a in the longitudinal direction. The gutter end member 10 has a through hole 12 (Figure 2) for attaching a drain 20, and the gutter 81 and the downpipe 85 are connected via the drain 20.

[0015] The stopper member 86 closes the end of the main body 81a opposite to the end to which the gutter stopper member 10 is attached. The gutter 81 may be gently sloped from the stopper member 86 side to the gutter stopper member 10 side. In this case, the gutter 81 can efficiently send rainwater that falls on the roof 101 to the downpipe 85.

[0016] As shown in Figure 2, the eaves gutter end member 10 is a member attached to one end in the length direction of the eaves gutter 81, which includes a bottom plate 11, a rear wall 15 rising from the bottom plate 11 and disposed on the outer wall 70 (Figure 1) side of the building, a front wall 16 rising from the bottom plate 11 and disposed on the side opposite to the outer wall 70, and a side wall 17 rising from the bottom plate 11 and disposed at the end on the side opposite to the eaves gutter 81 (Figure 1). That is, when the eaves gutter end member 10 is installed at the left end of the eaves gutter 81 as shown in Figure 1, the right side in Figure 2 is the outer wall 70 side.

[0017] The eaves gutter end member 10 is formed by injection molding a synthetic resin such as vinyl chloride resin, and has a cross-sectional groove shape of a size that receives the eaves gutter 81. The eaves gutter end member 10 includes a drain attachment portion 1 for attaching the drain 20, and an eaves gutter connection portion 2 connected to the eaves gutter side end of the drain attachment portion 1, and the drain attachment portion 1 and the eaves gutter connection portion 2 are integrally formed.

[0018] The drain attachment portion 1 further includes a side wall 17 on the side opposite to the eaves gutter connection portion 2. The side wall 17 closes the downstream end of the eaves gutter 81.

[0019] The bottom plate 11 has a through hole 12 for attaching the drain 20 to be described later. As will be described in detail later, the drain 20 is disposed to connect the eaves gutter 81 installed in a substantially horizontal direction and the downspout 85 installed in a vertical direction, and is a drainage member that suppresses the influence of foreign matter such as fallen leaves mixed into the eaves gutter 81, collects only rainwater, and guides the water to the downspout 85. As will be described later with reference to Figure 3, the drain 20 is composed of an upper member 30 having an upper flange 31 and a lower member 40 having a lower flange 42.

[0020] The eaves gutter connection portion 2 includes intermediate walls 2a, 2b provided on the inner surface side of the end on the drain attachment portion 1 side, and a protruding piece 18. The intermediate walls 2a, 2b protrude from the inner surfaces on both front and rear sides of the eaves gutter connection portion 2 in a substantially L-shape when viewed in the left-right direction. The front intermediate wall 2a is formed along the front wall 16 and the front portion of the bottom plate 11. The rear intermediate wall 2b is formed along the rear wall 15 and the rear portion of the bottom plate 11. The intermediate walls 2a, 2b are isolated from each other at the upper central portion of the bottom plate 11.

[0021] The protruding piece 18 is composed of a protruding piece 18a arranged along the front portion of the bottom plate 11, a protruding piece 18b extending from the front end of the protruding piece 18a along the front wall 16, a protruding piece 18c arranged along the rear portion of the bottom plate 11, and a protruding piece 18d extending from the rear end of the protruding piece 18c along the rear wall 15. The protruding piece 18 forms an insertion portion between the bottom plate 11, the rear wall 15 and the front wall 16 for inserting one end of the eaves gutter 81.

[0022] Furthermore, locking pieces 19 bent to face each other are formed from the upper ends of the front wall 16 and the rear wall 15 of the eaves gutter connection part 2. The locking pieces 19 are locked to the upper end of the eaves gutter 81 inserted inside the eaves gutter connection part 2, and guide the insertion of the eaves gutter 81. The intermediate walls 2a, 2b restrict the insertion of the eaves gutter 81 toward the drain mounting part 1 side. The front and rear intermediate walls 2a, 2b may be connected, and the front portion and the rear portion of the protruding piece 18 may be connected.

[0023] Next, the eaves gutter stop member 10 to which the drain 20 is fixed will be described in further detail with reference to FIG. 3. As shown in FIG. 3, the upper surface of the bottom plate 11 includes an upper counterbore 13 for locking the upper flange 31 of the drain 20, which will be described later, radially outward from the peripheral edge of the through hole 12. The upper counterbore 13 is provided at the peripheral edge of the through hole 12, and has a concave shape sized to receive the upper flange 31. The depth of the upper counterbore 13 is 1 mm or more and 3 mm or less. When the depth of the upper counterbore 13 is within the above range, the upper surface of the upper flange 31 is positioned flush with the upper surface of the bottom plate 11 of the eaves gutter stop member 10 or lower than the upper surface of the bottom plate 11, so that rainwater accumulated in the eaves gutter 81 can be efficiently guided to the downspout 85.

[0024] The lower surface of the bottom plate 11 includes a lower counterbore 14 for locking the lower flange 42 of the drain 20 described later, which extends radially outward from the peripheral edge of the through hole 12. The lower counterbore 14 is provided at the peripheral edge of the through hole 12, and has a recessed shape sized to receive the lower flange 42. The depth of the lower counterbore 14 is 1 mm or more and 3 mm or less. When the depth of the lower counterbore 14 is within the above range, the lower surface of the lower flange 42 is flush with the lower surface of the bottom plate 11 of the eaves gutter end member 10, or located above the lower surface of the bottom plate 11. As a result, the adhesive applied between the upper surface of the lower flange 42 and the lower surface of the bottom plate 11 to fix the drain 20 can be prevented from overflowing from the lower counterbore 14. In this case, the step of wiping off the adhesive is unnecessary, and workability is improved.

[0025] The center C of the through hole 12 is arranged closer to the rear wall 15 than the central position M1 between the lower inner ends of the front wall 16 and the rear wall 15, and arranged closer to the side wall 17 than the central position M2 between the lower inner end of the side wall 17 and the eaves gutter side edge 4. Specifically, where L1 is the shortest distance between the boundary 15a of the rear wall 15 and the upper surface of the bottom plate 11 and the center C of the through hole 12, and L2 is the shortest distance between the boundary 16a of the front wall 16 and the upper surface of the bottom plate 11 and the center C of the through hole 12, L1<L2. Where L3 is the shortest distance between the eaves gutter side edge 4 and the center C of the through hole 12, and L4 is the shortest distance between the boundary 17a of the side wall 17 and the upper surface of the bottom plate 11 and the center C of the through hole 12, L4<L3. In this case, the drain 20 is fixed near the rear wall 15 and near the side wall 17 of the eaves gutter end member 10. As described above, since the downspout 85 is connected to the lower portion of the drain 20, by providing the center C of the through hole 12 of the eaves gutter end member 10 at the above position, the downspout 85 connected to the lower portion can be constructed close to the later-described column 71 provided at the external corner of the building 100.

[0026] Preferably, the center C of the through hole is disposed closer to the side wall 17 than the central position M2a between the boundary 17a, which is the lower end of the inner surface of the side wall 17, and the eaves gutter side edge 3 of the drain mounting part 1. Specifically, when the shortest distance between the eaves gutter side edge 3 and the center C of the through hole 12 is defined as L5, and the shortest distance between the boundary 17a between the side wall 17 and the upper surface of the bottom plate 11 and the center C of the through hole 12 is defined as L4, L4 < L5. In this case, the drain 20 is fixed closer to the rear wall 15 of the eaves gutter stop member 10 and further closer to the side wall 17. As described above, since the downspout 85 is connected to the lower part of the drain 20, by providing the center C of the through hole 12 of the eaves gutter stop member 10 at the above position, the downspout 85 connected to the lower part can be constructed further closer to a later-described column 71 provided at the external corner of the building 100.

[0027] Next, the drain 20 attached to the eaves gutter stop member 10 will be described in detail with reference to Figures 4 and 5. Figure 4 is a perspective view of the drain 20 attached to the eaves gutter stop member 10 as an example of the embodiment, showing a state in which the upper member 30 and the lower member 40 are combined, as viewed from above. Figure 5 is a cross-sectional view showing a use state in which the drain 20 is attached to the eaves gutter stop member 10 as an example of the embodiment.

[0028] As shown in Figures 4 and 5, the drain 20 is composed of an upper member 30 and a lower member 40. The upper member 30 is installed on the eaves gutter stop member 10 so as to penetrate through the through hole 12 (see Figure 3). The upper member 30 of the drain 20 has an upper flange 31 installed on the upper surface of the bottom plate 11 of the eaves gutter stop member 10, an upper cylindrical portion 32 (water collection cylinder) provided below the upper flange 31, and an upper curved surface portion 33 connecting the upper flange 31 and the upper cylindrical portion 32. The upper cylindrical portion 32 has a substantially cylindrical shape, and a male thread 34 capable of threadedly engaging with a later-described female thread 44 of the lower member 40 is formed on the outer peripheral surface of the upper cylindrical portion 32.

[0029] The upper member 30 is configured to include vanes 35 connected to a plurality of positions in the circumferential direction on the upper surface of the upper flange 31 and the inner peripheral surface of the upper curved surface portion 33, an inner cylindrical portion 36 connected to the radially inner ends of the vanes 35, and a funnel portion 37 continuing to the upper end of the inner cylindrical portion 36.

[0030] The funnel portion 37 extends radially outward in a trumpet shape, continuously from the upper end of the inner cylinder portion 36 upward. The conical inner and outer circumferential surfaces of the funnel portion 37 and the inner and outer circumferential surfaces of the inner cylinder portion 36 are smoothly connected by a curved surface that includes a curved surface with a circular arc cross-section.

[0031] The upper member 30 is formed by injection molding of a resin such as rigid polyvinyl chloride, polycarbonate, or ABS, but is not limited to these. The upper member 30 may also be made of metal.

[0032] The lower member 40 of the drain 20 has a lower cylindrical portion 41 (drain pipe), an outward-facing lower flange 42 formed at the upper end of the lower cylindrical portion 41, and a lower reduced-diameter portion 43. The inner circumferential surface of the lower reduced-diameter portion 43 is a tapered surface with a straight cross-section, and the outer circumferential surface of the lower reduced-diameter portion 43 is a curved surface with a circular arc cross-section. A stepped portion 43a extending radially inward is provided at the lower end of the lower reduced-diameter portion 43. The inner circumferential surface of the lower reduced-diameter portion 43 may be a curved surface with a circular arc cross-section, and the outer circumferential surface of the lower reduced-diameter portion 43 may be a tapered surface with a straight cross-section.

[0033] Female threads 44 are formed on the inner circumferential surface of the lower cylindrical portion 41 of the lower member 40. The female threads 44 are formed intermittently in the circumferential direction of the lower cylindrical portion 41, but may also be formed intermittently. The lower member 40 is connected to the downpipe 85 by fitting the lower cylindrical portion 41 inside the upper end of the downpipe 85. The lower surface of the stepped portion 43a may be in contact with the upper end of the downpipe 85.

[0034] The lower member 40 is formed by injection molding of a resin such as rigid polyvinyl chloride resin, polycarbonate, or ABS, but is not limited to these. The lower member 40 may also be made of metal.

[0035] The upper member 30 of the drain 20 is installed in the through hole 12 of the gutter end member 10, with the upper cylindrical portion 32 of the upper member 30 protruding downward from the through hole 12, and the male thread 34 formed on the outer circumference of the upper cylindrical portion 32 is screwed into the female thread 44 of the lower member 40. In this state, the lower flange 42 of the lower member 40 and the upper flange 31 of the upper member 30 sandwich the bottom plate 11 of the gutter end member 10 from both above and below, thereby fixing the drain 20 to the gutter end member 10. In this case, the upper flange 31 is received by the upper counterbore 13 provided on the upper surface of the bottom plate 11. The lower flange 42 is received by the lower counterbore 14 provided on the lower surface of the bottom plate 11.

[0036] The thickness (T1) of the bottom plate 11 in the portion where the upper counterbore 13 and lower counterbore 14 are provided is the same as the thickness of the bottom plate 84 of the gutter 81. The drain 20 is a drainage member that is conventionally attached to the middle portion of the gutter 81 via a through hole provided in the bottom plate 84 of the gutter 81. If the thickness of the bottom plate 11 in the portion where the upper counterbore 13 and lower counterbore 14 are provided in the gutter end member 10 is the same as the thickness of the bottom plate 84 of the gutter 81, it becomes possible to unify the material for the gutter and the gutter end member 10, and the drain 20 can be installed with the same ease of installation as when it is installed in a conventional gutter 81.

[0037] Next, using Figure 6, the installation location of the downpipe 85 constituting the rainwater drainage structure 80 when the gutter stop member 10 is used will be explained. The downpipe 85 is supported on the exterior wall 70 of the building 100 by a support fixed to a column 71 that constitutes the outer corner of the building 100. The support includes a brace 73 that is locked to the downpipe 85 by a known method and screws 74 that fix the brace 73 to the exterior wall 70. A furring strip 72, which is the exterior wall base, is interposed between the exterior wall 70 and the column 71. By positioning the center C of the through hole 12 of the gutter stop member 10 at the above position, the drain 20 can be fixed closer to the rear wall 15 and the side wall 17 of the gutter stop member 10, and the downpipe 85 connected to the lower part of the drain 20 can be installed closer to the column 71 that constitutes the outer corner of the building 100. Since the downpipe 85 can be installed close to the corner of the building 100, the appearance of the rainwater drainage structure 80 equipped with the downpipe 85 can be improved while increasing the ease of construction. In addition, since the downpipe 85 can be fixed to the column 71 that constitutes the corner of the building 100, the downpipe 85 can be firmly fixed to the exterior wall 70 compared to a downpipe connected to the middle part of the eaves gutter 81.

[0038] As described above, the gutter stopper member and rainwater drainage structure with the above configuration can receive the drain flange and efficiently guide rainwater to the downpipe. In addition, the downpipe can be installed closer to the exterior corners of the building, improving the appearance.

[0039] The above embodiments can be modified as appropriate without impairing the purpose of this disclosure. In the above embodiments, the gutter end member 10 is attached to the left end of the gutter 81 which extends in the left-right direction, but the design may be modified so that it is attached to the right end.
