Description

Technical Field

[0001] The present disclosure relates to a downspout fitting and a rainwater drainage structure including a fixing part fixed to an outer wall surface of a building and a downspout support part for supporting a downspout.

Background Art

[0002] Conventionally, rainwater flowing down to an eaves gutter attached to the eaves tip of a building roof is collected and sent to a downspout, and is discharged from the lower side through the downspout. Also, rainwater falling on the upper part of a building is taken in from a water intake and discharged from the lower side through the downspout.

[0003] Patent Document 1 describes that rainwater falling on the upper part of a building is sent to a branch part through a water intake and a leader, and is distributed from the branch part to two downspouts close to each other and flows downward. Patent Document 1 also describes that support parts for supporting two downspouts are provided at both ends of a connecting part provided below the branch part, and the connecting member is fixed to the building by a screw penetrating through the central part of the connecting member. The connecting member corresponds to a downspout fitting. In this configuration, since a plurality of downspouts are used to drain rainwater, when treating the same amount of rainwater as in the conventional case, the diameter of each downspout can be reduced, and thereby the appearance of the building can be improved.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, it is conceivable to connect the upper ends of a plurality of downspouts that are close to each other to the eaves gutter or the roof part, and drain the rainwater from the eaves gutter to each downspout. However, in order to fix each of the plurality of downspouts to the building, it is necessary to fix each of the plurality of downspouts to a plurality of main columns and intermediate columns that are arranged far apart from each other on the inner side of the outer wall surface of the building using brackets. In this case, the number of construction man-hours increases, and since a relatively large number of conspicuous downspouts are arranged at a relatively large distance from each other, it causes damage to the appearance of the building.

[0006] On the other hand, in the configuration described in Patent Document 1, it is possible to improve the appearance by draining rainwater using two adjacent downspouts, and it is also possible to reduce the number of construction man-hours by reducing the number of brackets for fixing the downspouts. However, in the configuration described in Patent Document 1, a screw penetrates through the central portion in the left-right direction of the connecting member corresponding to the bracket for the downspout. As a result, when the bracket is viewed from the front side, the screw is easily visible, so there is room for improvement in terms of improving the appearance.

[0007] Therefore, an object of the present disclosure is to provide a bracket for a downspout that can be used in a rainwater drainage structure for draining rainwater using a plurality of adjacent downspouts, can reduce the number of construction man-hours in the rainwater drainage structure, and can improve the appearance of the rainwater drainage structure, and a rainwater drainage structure including the bracket for the downspout.

Means for Solving the Problems

[0008] The bracket for a downspout according to the present disclosure is a bracket for a downspout including a fixing portion fixed to the outer wall surface of a building and at least two downspout support portions that support at least two downspouts, wherein the fixing portion is provided on the outer wall surface side of one of the two downspout support portions, and a connecting portion that extends from the fixing portion toward the other downspout support portion of the two downspout support portions and is connected to the other downspout support portion. The rainwater drainage structure according to the present disclosure is a rainwater drainage structure including an eaves gutter, a plurality of downspouts connected to the eaves gutter, and a bracket for a downspout that supports the plurality of downspouts and is fixed to the outer wall surface of a building, wherein the bracket for a downspout is the bracket for a downspout according to the present disclosure. [Effect of the Invention]

[0009] According to the vertical gutter control tool of one aspect of the present disclosure, it can be used in a rainwater drainage structure that drains rainwater using a plurality of adjacent vertical gutters, and can reduce the construction man-hours in the rainwater drainage structure and improve the appearance of the rainwater drainage structure.

[0011] Hereinafter, embodiments of the vertical gutter control tool according to the present disclosure will be described with reference to the drawings. The shapes, arrangements, numbers, materials, etc. described below are examples for explanation and can be appropriately changed according to the specifications of the vertical gutter control tool. In the following, the same reference numerals will be given to equivalent elements in all the drawings for explanation.

[0012] Embodiments will be described with reference to FIGS. 1 to 8. FIG. 1 is a perspective view showing a part of a building 100 in which a rainwater drainage structure 1 including a downspout fitting 10 for a downspout according to the embodiment is installed. In the building 100 where the rainwater drainage structure 1 is provided, an eaves gutter 104 is attached to the eaves tip of the roof 103. The rainwater drainage structure 1 includes an eaves gutter 104, a plurality of downspouts 2 connected to the eaves gutter 104, and a downspout fitting 10 that supports the plurality of downspouts 2 and is fixed to the outer wall surface 101 of the building 100. Specifically, the eaves gutter 104 has a cross-sectional groove shape in which the lower ends of a front wall 105 and a rear wall 106 divided in the front-rear direction are connected by a bottom plate 107 and extends in the left-right direction. Note that the "left-right direction" means the left-right direction when viewed from the front side facing the outer wall surface 101 to which the downspout fitting 10 described later is attached in this specification. Also, the front side is the front side, the rear side is the outer wall surface 101 side, and the direction connecting the front side and the outer wall surface side is the front-rear direction.

[0013] The eaves gutter 104 is suspended and supported by a suspension tool (not shown) attached to the building 100, for example, and is attached to the eaves of the roof 103 and arranged to receive rainwater flowing down from the roof. The eaves gutter 104 has an open upper surface and both left and right ends are closed. Drain holes (not shown) are formed at two positions in the lateral direction close to the middle of the bottom plate 107 of the eaves gutter 104. The upper vertical gutter 109 is connected to each drain hole via a drain 108. At the lower end of the vertical gutter 109, a lower vertical gutter 2 extending vertically near the outer wall surface 101 of the building 100 is connected via a first elbow 110, a downspout 111, and a second elbow 112. Further, a plurality of vertical positions in the vertical direction of each vertical gutter 2 are fixed to the outer wall surface 101 via a plurality of vertical gutter holders 10 described later. Each vertical gutter 2 discharges rainwater downward. At this time, the lower end of each vertical gutter 2 is connected to a drain pit (not shown) via a drain pipe cover 5 and a drain pipe (not shown) buried in the ground. A pipe connected to a sewer pipe is connected to the drain pit. The rainwater drainage structure 1 includes the eaves gutter 104, two drains 108, vertical gutters 109, a first elbow 110, a downspout 111, a second elbow 112, and vertical gutters 2, a plurality of vertical gutter holders 10, and a drain pipe cover 5. In the rainwater drainage structure 1, the rainwater in the eaves gutter 104 is sent to the drain pipe cover 5 via the drains 108, vertical gutters 109, first elbow 110, downspout 111, second elbow 112, and vertical gutters 2, and is sent from the drain pipe cover 5 to the drain pit via the drain pipe.

[0014] In this example, a plurality of vertical positions in the vertical direction of the two vertical gutters 2 are fixed to the outer wall surface 101 of the building 100 via the vertical gutter holders 10. Hereinafter, the configuration of the vertical gutter holders 10 will be mainly described.

[0015] FIG. 2 is a perspective view of a part of the two vertical gutters 2 in the A portion of FIG. 1 cut, as seen from the front side, showing the two vertical gutters 2 and the vertical gutter holders 10 attached to the two vertical gutters 2. FIG. 3 is a perspective view of the structure shown in FIG. 2 as seen from above. FIG. 4 is a front view of the structure shown in FIG. 2. FIG. 5 is a view of the structure shown in FIG. 2 as seen from the right side. Here, up and down mean up and down in a state where the vertical gutter 2 is fixed to the outer wall surface 101 via the vertical gutter holder 10.

[0016] As shown in FIGS. 2 to 5, the riser pipe retainer 10 is arranged behind two riser pipes 2 that extend in the vertical direction and are spaced apart in the left - right direction while being close to each other in the left - right direction. The riser pipe retainer 10 grips two vertical riser pipe claw portions 3 and 4 that are provided on the rear surface of each riser pipe 2 and extend in the vertical direction, thereby supporting the two riser pipes 2. Each of the vertical riser pipe claw portions 3 and 4 projects in the front - rear direction from two positions on the left and right of the rear surface of the riser pipe 2, and is bent at a substantially right angle so as to be separated from each other at the rear end and is tapered.

[0017] The riser pipe retainer 10 is fixed to the outer wall surface 101 by a mounting screw 70 that is attached so as to project from the rear end. At this time, it is preferable that the mounting screw is screwed and fixed to a main column or an intermediate column arranged inside the outer wall surface. In a house, the distance between adjacent intermediate columns is usually about 900 mm.

[0018] FIG. 6 is a perspective view of the riser pipe retainer 10 seen from the same direction as FIG. 2. FIG. 7 is a view seen from above of the structure shown in FIG. 2. FIG. 8 is a cross - sectional view taken along line B - B of FIG. 5.

[0019] As shown in FIGS. 6 to 8, the riser pipe retainer 10 has a horizontally long rectangular shape with a constant height in the vertical direction in a front view, and is in a mountain - shaped block form with a top provided offset to one side in the left - right direction (the left side in FIG. 7) in a top view. The riser pipe retainer 10 includes a block - shaped fixing portion 12 having a fixing surface 13 that corresponds to the mountain - shaped top and is fixed in contact with the outer wall surface 101. The riser pipe retainer 10 includes only one fixing portion 12. Further, the riser pipe retainer 10 includes two riser pipe support portions 14 and 16 that are integrally provided on the fixing portion 12 and are provided apart from each other in the left - right direction, and a connecting portion 50.

[0020] As shown in FIG. 8, a hole 12a through which a mounting screw 70 for fixing to the outer wall surface penetrates is formed in the fixing portion 12 in the front - rear direction. The riser pipe retainer 10 is integrally formed of, for example, resin or the like. Note that the riser pipe retainer 10 may be formed of a metal such as a stainless alloy or iron. Hereinafter, the riser pipe retainer 10 is referred to as the retainer 10.

[0021] On the front side, which is the side opposite to the outer wall surface 101 side of the fixing part 12, a pressing part 28, which will be described later, is provided so as to protrude forward. On the front ends of the portions of the fixing part 12 that sandwich the pressing part 28 from both the left and right sides, shoulders 12b and 12c with different positions in the front-rear direction are provided. The left shoulder 12b is located on the rear side of the right shoulder 12c. In FIG. 8, in order to make the boundaries between components clear, the front end of the fixing part 12 is shown by solid lines L1 and L2, and the right end is shown by a two-dot chain line L3.

[0022] The two vertical gutter support parts 14 and 16 support the two left and right vertical gutters 2. The left vertical gutter support part 14 is provided on the front side of the fixing part 12 and has two fitting claw parts 20 and 21 on both sides in the left-right direction, and a block-shaped pressing part 28 provided so as to protrude forward from between the two fitting claw parts 20 and 21 in the left-right direction with respect to the fixing part 12 and having a front end in the shape of a rectangular parallelepiped. The rear edge of the outer peripheral surface of the left vertical gutter 2 is pressed against the front side surface of the pressing part 28. On the front side surface of the pressing part 28, the front end of a concave part 29 extending in the front-rear direction with a circular cross-section is open. At the bottom of the concave part 29, the front end of a through-hole 12a is open. A head 71 of a mounting screw 70 can be inserted into the concave part 29, and the bottom surface of the concave part 29 serves as a seating surface for the head 71. The fixing part 12 is fixed to the outer wall surface 101 by the mounting screw 70. At this time, the mounting screw 70 passes through the concave part 29, the head 71 is pressed against the bottom surface of the concave part 29, and the screw shaft 72 of the mounting screw 70 passes through the through-hole 12a.

[0023] Also, the width in the left-right direction of the fixing surface 13, which is the part in contact with the outer wall surface 101 of the fixing part 12, is equal to or smaller than the same diameter as the left vertical gutter 2 and is 12 mm or more.

[0024] The two fitting claw parts 20 and 21 correspond to the two vertical gutter claw parts 3 and 4 of the left vertical gutter 2 and are locked to the two vertical gutter claw parts 3 and 4. Among the two fitting claw parts 20 and 21, the left fitting claw part 20 is a plate-shaped part having an inclined plate part 22 that extends obliquely forward to the left from the front end of the left shoulder 12b of the fixing part 12, a front-rear direction plate part 23 that is connected to the front end of the inclined plate part 22 and extends in the front-rear direction, and a tapered locking part 24 that protrudes to the right from the side surface of the pressing part 28 at the tip of the front-rear direction plate part 23.

[0025] Of the two fitting claw portions 20 and 21, the right fitting claw portion 21 is a plate-shaped portion having a longitudinal plate portion 25 extending in the front-rear direction from the front end of the right shoulder portion 12c of the fixing portion 12, and a tapered locking portion 26 protruding leftward from the side surface of the pressing portion 28 at the tip of the longitudinal plate portion 25. Thus, the locking portions 24 and 26 of the fitting claw portions 20 and 21 are provided at the tips of the longitudinal plate portions 23 and 25 and can be locked with the longitudinal groove claw portions 3 and 4 of the left vertical groove 2.

[0026] The right vertical groove support portion 16 is connected to the right end portion of a connecting portion 50 described later, and has two fitting claw portions 30 and 31 on both left and right sides in the left-right direction, and a substantially rectangular parallelepiped block-shaped pressing portion 38 provided so as to protrude forward from between the two fitting claw portions 30 and 31 in the left-right direction with respect to the right end portion of the connecting portion 50. Each fitting claw portion 30, 31 will be described later.

[0027] The connecting portion 50 is an arm-shaped portion that extends from the fixing portion 12 toward the right vertical groove support portion 16 and is connected to the right vertical groove support portion 16. Further, the connecting portion 50 extends obliquely in the entire longitudinal direction of the connecting portion 50 from the right vertical groove support portion 16 toward the rear side, which is the outer wall surface 101 side, and toward the left side, which is the side of the mounting screw 70.

[0028] As shown in FIG. 8, an elongated recess 50a that opens on the lower surface and extends along the longitudinal direction of the connecting portion 50 is formed in the connecting portion 50. The recess 50a serves as a material-removing portion of the connecting portion 50 and aims to reduce the weight of the control tool 10.

[0029] A pressing portion 38 is provided so as to protrude forward at the front end of the right end portion of the connecting portion 50. At the front end of the portion that sandwiches the pressing portion 38 from both left and right sides among the front ends of the right end portion of the connecting portion 50, shoulder portions 51b and 51c having different front-rear positions are provided. The right shoulder portion 51c is located rearward of the left shoulder portion 51b. In FIG. 8, in order to make the boundaries between components distinguishable, the front end of the right end portion of the connecting portion 50 is indicated by solid lines L4, L5, and two-dot chain line L6.

[0030] Of the two fitting claw portions 30 and 31 that form the right vertical gutter support portion 16, the right fitting claw portion 31 is a plate-like portion having a longitudinal plate portion 33 extending in the front-rear direction from the front end of the right shoulder portion 51c of the connecting portion 50, and a tapered locking portion 34 protruding leftward from the side surface of the pressing portion 38 at the tip of the longitudinal plate portion 33. Of the two fitting claw portions 30 and 31, the left fitting claw portion 30 is a plate-like portion having a longitudinal plate portion 35 extending in the front-rear direction from the front end of the left shoulder portion 51b of the connecting portion 50, and a tapered locking portion 36 protruding rightward from the side surface of the pressing portion 38 at the tip of the longitudinal plate portion 35. Thereby, the locking portions 36 and 34 of the respective fitting claw portions 30 and 31 are provided at the tips of the longitudinal plate portions 35 and 33 and can be locked to the vertical gutter claw portions 3 and 4 of the right vertical gutter 2.

[0031] As shown in FIG. 7, of the two fitting claw portions 20 and 21 of the left vertical gutter support portion 14, the longitudinal length d1 from the locking surface (the upper surface in FIG. 7) of the locking portion 24 of the left fitting claw portion 20 to the root end T1 where the thickness changes is 1.4 times or more the longitudinal length d2 from the locking surface (the upper surface in FIG. 7) of the locking portion 26 of the right fitting claw portion 21 to the root end T2 where the thickness changes. More preferably, the length d1 is 1.5 times or more the length d2.

[0032] Also, of the two fitting claw portions 30 and 31 of the right vertical gutter support portion 16, the longitudinal length d3 from the locking surface (the upper surface in FIG. 7) of the locking portion 34 of the right fitting claw portion 31 to the root end T3 where the thickness changes is 1.4 times or more the longitudinal length d4 from the locking surface (the upper surface in FIG. 7) of the locking portion 36 of the left fitting claw portion 30 to the root end T4 where the thickness changes. More preferably, the length d3 is 1.5 times or more the length d4.

[0033] Furthermore, in a portion of the left side surface of the control tool 10 that includes the inclined plate portion 22 on the rear side of the rear end of the front-rear direction plate portion 23 at the left end, a first inclined surface S1 that inclines to the right toward the rear side is provided. Also, on the right side surface of the control tool 10, a second inclined surface S2 that inclines to the left toward the rear side is provided on the rear side of the rear end of the front-rear direction plate portion 33 at the right end. The second angle θ2, which is the angle formed by the second inclined surface S2 and the outer wall surface 101, is smaller than the first angle θ1, which is the angle formed by the first inclined surface S1 and the outer wall surface 101. By providing the first inclined surface S1, when the vertical gutter 2 and the control tool 10 are viewed from the left obliquely front side, the control tool 10 is hidden behind the vertical gutter 2 and becomes difficult to see. For example, when viewed from the rear side to the front side in the direction of arrow α in FIG. 7, the control tool 10 is hidden by the left vertical gutter 2 and becomes difficult to see. Thereby, the appearance of the rainwater drainage structure 1 can be further improved. For example, the first angle θ1 can be 60 degrees or less. Also, by providing the second inclined surface S2, as will be described later, when the control tool 10 is viewed from the right obliquely front side, the rear side of the control tool 10 becomes difficult to see.

[0034] In addition, the distance dL between the left and right two vertical gutter support portions 14 and 16 is preferably 10 mm or more and not more than the outer diameter of one vertical gutter 2, for example, 45 mm or less. When the distance dL is regulated in this way, it is possible to suppress the visibility of the horizontal lines La and Lb (FIG. 4) indicating the outer shape of the control tool 10 between the two vertical gutters 2, and it becomes easier to appropriately secure the distance between the drain holes of the eaves gutter 104 to which the upstream end of the vertical gutter 2 is connected and the diameter of the pipe portion that is fitted and connected to the outside of the downstream end of the vertical gutter 2.

[0035] The above-described control tool 10 is fixed at a predetermined position in the vertical direction on the outer wall surface 101 by mounting screws 70 before being supported by the two vertical gutters 2. In the configuration shown in FIG. 1, a plurality of control tools 10 are fixed at a plurality of predetermined positions in the vertical direction on the outer wall surface 101. Thereafter, the vertical gutter claws 3 and 4 of the corresponding vertical gutter 2 are locked by the locking portions 24, 26, 34, and 36 of the vertical gutter support portions 14 and 16 of each control tool 10, and the vertical gutter 2 is fixed to each vertical gutter support portion 14 and 16.

[0036] According to the above-mentioned brace 10, it can be used for the rainwater drainage structure 1 that drains rainwater by using two adjacent vertical gutters 2. Thereby, when treating the same amount of rainwater as in the prior art, the diameter of each vertical gutter 2 can be reduced, so that the depth of the rainwater drainage structure 1 in the front-rear direction can be reduced. For this reason, the appearance of the building 100 including the rainwater drainage structure 1 can be improved.

[0037] Moreover, as the brace 10, it is sufficient to have a plurality of braces 10 that commonly support the two vertical gutters 2. It is not necessary to fix the two vertical gutters 2 to the outer wall surface 101 using separate braces 10. Thereby, the number of construction man-hours in the rainwater drainage structure 1 can be reduced. Further, among the braces 10, mounting screws 70 for fixing to the outer wall penetrate through the left end portion, which is a portion hidden from the front side by the left vertical gutter 2. Thereby, when the brace 10 is viewed from the front side, the mounting screws 70 are not visible, so that the appearance of the rainwater drainage structure 1 can be improved.

[0038] Further, the brace 10 includes a connecting portion 50 that extends from the fixing portion 12 toward the right vertical gutter support portion 16 and is connected to the right vertical gutter support portion 16. Also, two vertical gutter support portions 14, 16 for supporting the two vertical gutters 2 are provided on the front side of the connecting portion 50. Thereby, it is not necessary to provide the brace 10 in the horizontal intermediate region sandwiched between the two vertical gutter support portions 14, 16 on the front side of the connecting portion 50 indicated by the two-dot chain line frame C in FIG. 8, and a space 120 can be formed in that portion. Thereby, when the two vertical gutters 2 are viewed from the front side, the portion of the brace 10 that is visible between the two vertical gutters 2 can be arranged closer to the outer wall surface 101 side, so that sunlight hitting the brace 10 can be suppressed. For this reason, deterioration of the brace 10 due to sunlight can be suppressed. Also, when the two vertical gutters 2 are viewed from the front side, compared with the case where only the vertical outer contour lines of the vertical gutters 2 are visible, the horizontal lines La, Lb, which are the outer contour lines of the brace 10 between the two vertical gutters 2, are more conspicuous and are likely to be noise in the appearance of a building such as a house. On the other hand, in this example, since the lines La, Lb of the brace 10 are located more rearward with respect to the rear ends of the vertical gutters 2, the adverse effect on the appearance of the building can be reduced.

[0039] Further, the connecting portion 50 extends obliquely toward the mounting screw 70 side from the right vertical gutter support portion 16 toward the outer wall surface 101 side. As a result, as described above, a second inclined surface S2 can be formed on the right side surface of the switchgear 10, which can reduce the second angle θ2, which is the angle formed by the outer wall surface 101 and the second inclined surface S2. For this reason, when the switchgear 10 is viewed from the right front side, the rear side of the switchgear 10 becomes difficult to see. For example, when viewed from the rear side in the direction of arrow β in FIG. 7 toward the front side, the rear side portion of the switchgear 10 becomes difficult to see. Thereby, the appearance of the rainwater drainage structure 1 can be further improved. Further, since the area of the portion of the switchgear 10 that contacts the outer wall surface 101 can be reduced, it is possible to suppress the accumulation of deposits such as rainwater and sand between the outer wall surface 101 and the switchgear 10. Thereby, the risk of dirt such as blackening occurring on the outer wall surface 101 can be reduced.

[0040] Also, the lateral width of the fixing surface 13, which is the portion of the fixing portion 12 that contacts the outer wall surface 101, is equal to or less than the same diameter as the vertical gutter 2 and is 12 mm or more. Thereby, since the area of the portion of the switchgear 10 that contacts the outer wall surface 101 can be further reduced, it is possible to further suppress the accumulation of deposits such as rainwater and sand between the outer wall surface 101 and the switchgear 10. For this reason, the risk of dirt such as blackening occurring on the outer wall surface 101 can be further reduced. Also, since the lateral width of the portion of the fixing portion 12 that contacts the outer wall surface 101 is 12 mm or more, this width can be made equal to or larger than the outer diameter of the head of a general screw used as the mounting screw 70. For this reason, the coupling strength between the switchgear 10 and the outer wall surface 101 can be ensured to be equal to or higher than the strength required in practical use.

[0041] Also, in each of the vertical gutter support portions 14 and 16, the longitudinal lengths d1 and d3 from the locking surfaces of one of the two fitting claw portions 20, 21, 30, 31 to the root ends T1 and T3 where the thickness changes are 1.4 times or more, more preferably 1.5 times or more, the longitudinal lengths d2 and d4 from the locking surfaces of the other fitting claw portions 21, 30 to the root ends T2 and T4 where the thickness changes. Thereby, it becomes easier to give spring properties to one of the fitting claw portions 20, 31. By elastically deforming one of the fitting claw portions 20, 31, the operation of locking the two vertical gutter claw portions 3 and 4 of the vertical gutter 2 to the two fitting claw portions 20, 21, 30, 31 becomes easier, and the workability can be improved. Also, since the other fitting claw portions 21, 30 can have high bending rigidity, a structure in which the vertical gutter claw portions are difficult to come off from the fitting claw portions due to external disturbances can be realized. When attaching the vertical gutter 2 to the switch box 10, first, after inserting one of the vertical gutter claw portions of the vertical gutter 2 into the other fitting claw portions 21, 30 from the obliquely front side, the one fitting claw portions 20, 31 are elastically expanded outward, and the other vertical gutter claw portion of the vertical gutter 2 is inserted into the one fitting claw portions 20, 31, whereby the two vertical gutter claw portions can be locked to the two fitting claw portions.

[0042] FIG. 9(a) is a schematic diagram corresponding to FIG. 7 showing a first example of another example of the embodiment. FIG. 9(b) is a schematic diagram corresponding to FIG. 7 showing a second example of another example of the embodiment.

[0043] The switch box 10a of the first example of the other example shown in FIG. 9(a) is the same as the configuration of FIGS. 1 to 8, except that the ratio (F / E) of the protruding dimension F to the interval E between the two vertical gutters 2 is increased. The protruding dimension F is the length from the outer wall surface 101 to the rear end edge of the outer peripheral surface of the vertical gutter 2.

[0044] The second example of the control tool 10b shown in FIG. 9(b) has the same ratio (F / E) of the protruding dimension F to the interval E as the first example of the control tool 10a shown in FIG. 9(a). Further, in the second example of the alternative example, the connecting portion 50a has an inclined portion 51 that extends obliquely toward the mounting screw side from the right vertical gutter support portion 16 toward the outer wall surface 101 side, and a laterally extending portion 52 that extends along the left-right direction from the end of the inclined portion 51 on the outer wall surface 101 side toward the fixing portion 12. Thereby, in the second example of the alternative example, a front-rear gap da is formed between the rear side surface of the laterally extending portion 52 and the outer wall surface 101. At this time, the gap da is, for example, 3 mm or more. Further, the second angle θ4, which is the angle formed by the second inclined surface S2, which is the right side surface of the inclined portion 51, and the outer wall surface 101, is 80 degrees or less.

[0045] In both the first example of the alternative example shown in FIG. 9(a) and the second example of the alternative example shown in FIG. 9(b), the second angles θ3 and θ4, which are the angles formed by the second inclined surface S2 on the right side of the connecting portion 50 and the outer wall surface 101, are 80 degrees or less. Thereby, when the control tool 10 is viewed from the right front diagonal side, the rear side of the control tool 10 becomes difficult to see. For this reason, the appearance of the rainwater drainage structure can be improved. In particular, in the case where the protruding dimension F, which is generally long in the conventional rainwater drainage structure, is 60 mm or less, it is preferable that the second angles θ3 and θ4 are 80 degrees or less because the rear side of the control tool 10 becomes difficult to see.

[0046] Furthermore, in the first example of the alternative example shown in FIG. 9(a), similar to the configuration shown in FIGS. 1 to 8, the connecting portion 50 extends obliquely in the entire longitudinal direction of the connecting portion 50 from the right vertical gutter support portion 16 on the right side of the connecting portion 50 toward the left side, which is the mounting screw side, on the rear side, which is the outer wall surface 101 side. As can be seen by comparing FIG. 9(a) and FIG. 9(b), in the first example of the alternative example, the second angle θ3, which is the angle formed by the second inclined surface S2 on the right side and the outer wall surface 101, is smaller than the second angle θ4 of the second example of the alternative example. For this reason, in the first example of the alternative example, when the control tool 10 is viewed from the right front diagonal side, the rear side of the control tool 10 becomes even more difficult to see. For this reason, in the first example of the alternative example, compared with the second example of the alternative example, the effect of improving the appearance of the rainwater drainage structure becomes higher.

[0047] In a configuration where the protruding dimension is smaller than that of the configuration of FIG. 9(a), the control tool 10 becomes more difficult to be seen from the front side, so the effect of improving the appearance of the rainwater drainage structure is enhanced. For example, the protruding dimension is preferably 30 mm or less, and the second angle θ3 is preferably 70 degrees or less, for example, 69 degrees or less.

[0048] On the other hand, in the case where the connecting portion 50 extends obliquely over the entire longitudinal direction, the effect of improving the appearance becomes remarkable when the ratio (F / E) of the protruding dimension F to the interval E increases.

[0049] In each of the above embodiments, the left-right direction of the control tools 10, 10a, and 10b may be reversed so that the fixing portion 12 is located on the right side of the control tool. Further, the control tool may be configured to include three or more vertical gutter support portions that support three or more vertical gutters. For this reason, the rainwater drainage structure can also be configured to include three or more vertical gutters connected to the eaves gutter and a control tool for vertical gutters that supports the three or more vertical gutters and is fixed to the outer wall surface of the building. Further, among the plurality of vertical gutter support portions provided in the control tool 10, in only some of the vertical gutter support portions, the longitudinal length from the locking surface of one of the two fitting claw portions to the root end where the thickness changes is 1.4 times or more the longitudinal length from the locking surface of the other fitting claw portion to the root end where the thickness changes.

[0050] The present disclosure will be further described by the following embodiments. Configuration 1: A control tool for a vertical gutter, comprising a fixing portion fixed to an outer wall surface of a building and at least two vertical gutter support portions that support at least two vertical gutters, wherein the fixing portion is provided on the outer wall surface side of one of the two vertical gutter support portions, and a connecting portion that extends from the fixing portion toward the other vertical gutter support portion of the two vertical gutter support portions and is connected to the other vertical gutter support portion.
