<Eave gutter structure>
Next, the eaves gutter structure A of this embodiment will be described.
The eaves gutter structure A includes an eaves gutter 10, a vertical gutter 100, and an overflow gutter 200, as shown in the schematic explanatory diagram of FIG. In FIG. 3, for easy understanding, the position of the outlet of the downspout 100 is indicated by a triangle, and the position of the outlet 213 of the overflow gutter 200 is indicated by a black circle. It does not show the shape of.

First, the eaves gutter 10 is arranged along the eaves of the roof L. The eaves gutter 10 is made of resin or metal, and has a substantially U-shaped cross-section having rising portions 12 and 13 on the eaves tip side and the eaves base side of the bottom plate 11, as shown in FIG. 4 (FIG. 1). ing.
The eave gutter 10 is attached to the eave arm 25 by the gutter receiving fitting 25a as described above.

Further, the eaves gutter 10 is inclined and disposed with a drainage gradient. That is, the arrow DS shown in FIG. 3 indicates a state of inclination of the eaves gutter 10, and a vertical gutter 100 is provided at the lowest position (under water) of the drainage gradient. On the other hand, an overflow gutter 200 is provided at the highest position (above the water) of the drainage gradient.
The downspout 100 is well known, and extends from the eaves trough 10 along the outer wall of the building H to the ground or below the ground. Further, the eaves gutter 10 has the vertical gutter 100 and the overflow gutter 200 for each building unit 20, but is not limited thereto.

<Overflow gutter>
Next, the overflow gutter 200 will be described. In the following description, FIG. 1 is always referred to.
As shown in FIG. 4 (FIG. 5), the overflow gutter 200 is located at a position (upper position) lower than the upper ends of the rising portions 12 and 13 of the eaves gutter 10 and higher than the bottom surface (bottom plate 11). 213, and a drain port 234 on (the lower surface side of) the eave ceiling 40. When the water level of the eaves gutter 10 exceeds the height (h1) of the outlet 213, the overflow gutter 200 drains water from the drainage outlet 234 of (the lower surface side of) the eaves ceiling 40.

  The overflow gutter 200 includes an upper vertical pipe 210 and a lower vertical pipe 220. A drain member 230 is attached to the lower vertical tube 220, and a lid member 240 is attached to the upper vertical tube 210.

The upper vertical pipe 210 is a pipe member having a circular cross section provided through the bottom plate 11 of the eaves gutter 10 and includes a water collecting section 212 shown in FIG. 6A and a drain section 211 shown in FIG. 6B.
As shown in FIG. 6B (FIG. 4), the drain part 211 is mainly configured by a small-diameter pipe part 211b (drain pipe) having a relatively small diameter. At the upper end of the small-diameter tube portion 211b, a large-diameter tube portion 211a (connection portion) having a step portion and having a relatively large diameter is integrally formed. The large-diameter pipe portion 211a has a size that can be fitted onto the water collecting portion 212. A female screw 211d is formed on the inner circumference 211c of the large-diameter tube portion 211a. An annular flange 211f (outer flange) extending in the circumferential direction is integrally formed on the outer periphery of the upper end of the large-diameter pipe portion 211a.

On the other hand, as shown in FIG. 6A, the water collecting section 212 is mainly configured by a main body 212a (water collecting pipe) having a tubular shape with a circular cross section. An annular flange 212f (outer flange) extending in the circumferential direction is integrally formed on the outer periphery of the lower portion of the main body 212a.
An upper male screw 212b that meshes with a female screw 243 of the lid member 240 described later is formed on the outer periphery of the upper end of the main body 212a. A lower male screw 212d that meshes with the female screw 211d of the drain portion 211 is formed on the outer periphery of the lower end of the main body 212a.
Further, at the upper part of the main body 212a, a single opening 213a penetrating between the inside and the outside is provided, or a plurality of openings 213a are provided at intervals in a circumferential direction. Thereby, when the water level of the eaves gutter 10 rises to the height of h1 in FIG. 4 which is the height of the lower end of the opening 213a, the water in the eaves gutter 10 flows into the water collecting part 212. The opening 213a has a vertical dimension larger than a horizontal gap 244 (FIG. 4) between the opening 213a and the lid member 240, as described later. The opening 213a has, for example, a vertical dimension larger than 15 mm and a circumferential dimension of about several cm.

  The upper vertical pipe 210 is fixed to the bottom plate 11 of the eaves gutter 10. This fixation is performed by screwing the lower male screw 212d of the water collecting part 212 into the female screw 211d of the drain part 211 described above.

That is, the drain portion 211 is disposed below the opening formed in the bottom plate 11, the lower portion of the main body 212 a of the water collecting portion 212 is inserted through the opening of the bottom plate 11 from above, and the two are relatively rotated to form the drain portion 211. The lower male screw 212d of the water collecting part 212 is screwed into the female screw 211d.
Thereby, the drain part 211 and the water collecting part 212 move close to each other in the axial direction, and as shown in FIG. 4, the flange 211f of the drain part 211 and the flange 212f of the water collecting part 212 move the bottom plate 11 from above and below. The upper vertical pipe 210 is fixed to the bottom plate 11 of the eaves gutter 10 because it is sandwiched. Further, since the upper vertical tube 210 is fixed by the engagement of the female screw 211d and the lower male screw 212d, there is no need to penetrate another fastening member or the like to the bottom plate 11, and the sealing performance is ensured. Easy.

The small-diameter pipe portion 211b of the drain portion 211 of the upper vertical pipe 210 is inserted into the upper portion of the lower vertical pipe 220 (FIG. 4).
The lower vertical pipe 220 is fixed to the eaves ceiling 40 by being connected to the drain member 230.
The lower vertical pipe 220 is mainly constituted by a pipe main body 221 (water retaining section) as shown in FIG. 7A. An annular flange 222 (outer flange) extending in the circumferential direction is integrally formed on an outer periphery of a lower portion of the pipe main body 221. Below the flange 222, a connecting tubular portion 223 extends integrally. The connecting tube 223 has a smaller diameter than the upper part of the tube main body 221.

At least the upper part of the pipe main body 221 is larger in diameter than the lower part, and is formed to have a larger diameter than the small diameter pipe part 211b of the drain part 211 of the upper vertical pipe 210 as described above.
A male screw 224 is formed on the outer periphery of the connecting cylinder 223.

As shown in FIG. 7B, the drain member 230 includes a short circular tubular portion 231, a circumferentially extending annular flange 232 (outer flange) provided integrally on the outer periphery of the upper end of the tubular portion 231, and a tubular portion. 231.
Note that a female screw 235 that can mesh with a male screw 224 formed on the outer circumference of the connecting cylinder 223 of the tube main body 221 is formed on the inner periphery of the cylinder 231.
The drain port 234 has a plurality of lower openings 234b for directing drain water downward, and a plurality of side openings 234a for directing drain water in an outer radial direction with respect to a direction along the central axis. I have. The lower opening 234b is appropriately partitioned by concentric ribs, radial ribs, and the like.

That is, when drainage is performed by the overflow gutter 200, the drainage member 230 drains from the side opening 234a so that the drainage flies to a certain extent in the horizontal direction, thereby reporting that drainage is being performed. ing.
On the other hand, by providing the lower opening 234b, the flow rate from the side opening 234a is restricted so that the drainage does not scatter over a wide area.

  The lower vertical pipe 220 and the drain member 230 are fixed to the eave ceiling 40 as shown in FIG. The fixing structure is also the same as that of fixing the upper vertical pipe 210 to the eaves gutter 10 described above, and the connection cylindrical portion 223 of the lower vertical pipe 220 is inserted into the opening (not shown) provided in the eaves ceiling 40 from above. It penetrates and is inserted into the cylindrical part 231 of the drain member 230 arranged below the eaves ceiling 40. Then, by rotating the lower vertical pipe 220 and the drain member 230 relatively, the male screw 224 is screwed into the female screw 235, and the eaves ceiling 40 is vertically sandwiched between the two flanges 222 and 232, whereby the lower vertical pipe 220 and the drain are drained. The member 230 is fixed to the eave ceiling 40.

  As described above, the lower vertical pipe 220 and the upper vertical pipe 210 are separate bodies, and the upper part of the pipe main body 221 is formed to have a larger diameter than the small diameter pipe part 211b. Even if there is a deviation at the fixed position, deviation of the radius difference can be tolerated. In addition, since the upper vertical pipe 210 is vertically inserted into the lower vertical pipe 220, even if there is a deviation between the fixed positions in the axial direction, the insertion amount or the insertion margin is changed so that the upper and lower parts are changed. Direction deviation can be absorbed.

Further, a lid member 240 is fixed to the upper part of the overflow gutter 200, that is, to the upper end part of the water collecting part 212 of the upper vertical pipe 210 so as to cover the outlet 213.
The lid member 240 includes a lid plate 241, an annular wall 242, and a female screw 243.
The lid plate portion 241 covers the upper end opening of the upper vertical pipe 210 (the water collecting portion 212) facing upward, and is formed in a disk shape slightly larger in diameter than the outer diameter of the water collecting portion 212. ing.

  The annular wall portion 242 is formed in a short tube extending axially (downward) from the outer peripheral edge of the cover plate portion 241, and has a circumferential gap 244 between the annular wall portion 242 and the outer periphery of the water collecting portion 212. doing. The gap 244 has a horizontal interval of about several mm to 1 cm. This is to prevent entry of dust 60 such as dead leaves larger than the gap 244.

<Socket for overflow gutter>
Next, the overflow gutter socket 251 which is a feature of this embodiment will be described. In the following description, FIGS. 1 and 4 are always referred to.
This overflow gutter socket 251 is as shown in FIGS. 8A to 8D and is used as a part of an overflow gutter 200 provided between the eaves gutter 10 and the eaves ceiling 40 constituting the eaves of the building H. . As described above, the overflow gutter 200 includes the lower vertical pipe 220 attached to the eaves ceiling 40. And the lower vertical pipe 220 has a socket body 251 into which the upper vertical pipe 210 attached to the eaves gutter 10 can be inserted, whereby the overflow gutter socket 251 is configured.

  Here, the socket is a receptacle into which a device or the like is inserted. In this case, the lower vertical pipe 220 is a receiving port into which the (the small-diameter pipe portion 211b in the drain portion 211 of) the upper vertical pipe 210 is inserted. As described above, the lower vertical pipe 220 has at least an upper portion of the pipe main body 221 larger in diameter than the small-diameter pipe portion 211b of the upper vertical pipe 210. Therefore, the tube main body 221 functions as the socket main body 252 as it is. In this embodiment, the pipe main body 221 (socket main body 252) has a receiving portion 221a whose diameter is almost constant or slightly increases toward the upper side at the upper part thereof, and is contracted downward at the lower part thereof. It has a reduced diameter portion 221b. The small-diameter tube portion 211b of the upper vertical tube 210 is inserted at least to the position of the receiving portion 221a on the front side of the reduced-diameter portion 221b.

  The lower vertical pipe 220 serving as the overflow gutter socket 251 may have corners 253 and 254 at the bottom. The corners 253 and 254 are formed at positions outside the outer peripheral edge of the flange 222 having a substantially circular shape in plan view. The corner portions 253 and 254 can be provided at least at a position on the building side of the flange 222 or the like. The corners 253 and 254 may be provided singly or in a plurality. When a plurality of corners 253 and 254 are provided, a flat portion (flat portion 255) is formed by connecting the plurality of corners 253 and 254 together. At least one or more may be formed. In addition, the flange 222 can be formed in a polygonal shape or the like by connecting the plurality of corners 253 and 254 together. When the corners 253, 254 and the flat part 255 move in the circumferential direction, the corners 253, 254 and the flat part 255 hit or catch on external members such as the rising part 40a of the eaves ceiling 40, the eaves sky receiving material 41 and the bracket 41b. (FIG. 8B).

  Further, the lower vertical pipe 220 serving as the overflow gutter socket 251 may have a cutout 256 at the upper part. The notch 256 is provided at the upper edge of the tube body 221 (socket body 252). The notch portion 256 may include a notch formed, a notched shape, and the like. The shape of the cutout portion 256 is not limited, but may be a U-shaped or V-shaped recessed downward. The notch 256 is preferably provided at a position on the eaves side.

  Further, the lower vertical pipe 220 serving as the overflow gutter socket 251 may have a partition 258 inside. The partition part 258 is provided singly or plurally (with an interval in the circumferential direction) inside the pipe main body 221 (socket main body 252). In this embodiment, the number of the partition portions 258 is six, but the number is not limited thereto. The partition part 258 is provided at least in the part of the reduced diameter part 221b. The partition part 258 may be provided for the receiving part 221a. The partition part 258 has a length that reaches the position of the outer peripheral surface of the small-diameter tube part 211b, a length that exceeds the position of the outer peripheral surface, and a position of the outer peripheral surface, as viewed from above, inward from the inner peripheral surface of the pipe main body 221. It can be formed to a length that cannot be reached. The partition 258 may be radially extending toward the position of the central axis of the lower vertical pipe 220, or may be radially spiraling extending toward a position shifted from the central axis. The partition part 258 may be a current plate extending in the vertical direction, or may be a turning blade extending in a state inclined in the vertical direction. The partition 258 may be provided in a single stage or in multiple stages in the vertical direction.

(Operation of the embodiment)
Hereinafter, the operation of the eaves gutter structure A of the embodiment will be described.
When rain falls on the roof L of the building H, the rain flows in the direction of the arrow WL in FIG.
At this time, among the garbage 60 such as dead leaves, a relatively large garbage is blocked by the vertical wall portion 51 of the parapet cover 50 as shown in FIG.

The rainwater flowing into the eaves gutter 10 flows from above the water to below the water along the slope of the eaves gutter 10 as shown by an arrow DS in FIG. It is drained to such.
As described above, dust 60 such as relatively large dead leaves is prevented from entering the eaves gutter 10 by the vertical wall portion 51 of the parapet cover 50, but the dropout ( (Indicated by 口 in FIG. 3), and the opening may be closed.

As described above, when the downfall of the downspout 100 is closed and the drainage capacity of the downspout 100 is reduced, the water level of the eaves trough 10 rises when the amount of rainfall is large.
Then, when the water level on the water side where the overflow gutter 200 is provided in the eaves gutter 10 rises above the height h1 of the lower end of the opening 213a, the rainwater that has flowed in further is overflowed by the overflow gutter 200 to the outside of the eaves gutter 10. Drained. Therefore, the rise of the water level of the eaves gutter 10 is suppressed, and the overflow to the eaves ceiling 40 beyond the height ht of the rising portion 13 can be suppressed. The height h1 of the lower end of the opening 213a is set to approximately half the height ht of the rising portion 13.

  When the water is drained by the overflow gutter 200, the water is drained from the drain port 234 of the drain member 230 provided at the eaves ceiling 40, that is, from the vicinity of the lower surface of the eaves ceiling 40. Since the drainage from the drain member 230 of the eave ceiling 40 does not occur in a normal state, the resident recognizes the abnormality of the eaves gutter 10, that is, the clogging of the downspout 100 by the drainage from the drain member 230. can do.

  In particular, in this embodiment, since the overflow gutter 200 is arranged near the entrance space E as shown in FIG. 3, it is easy for a resident who enters or leaves the dwelling spaces S1 and S2 to recognize when going out or returning home. Has become.

  Further, since the drain port 234 of the drain member 230 is provided with the side opening 234a, a part of the drain scatters in the horizontal direction, and the resident can discharge the drain by the overflow gutter 200 more than the case where only the lower opening 234b is provided. Easy to recognize.

At this time, in order to prevent the overflow of the eaves gutter 10 by using the drainage from the overflow gutter 200 described above, the drainage capacity of the vertical gutter 100 and the drainage capacity of the overflow gutter 200 must be equal. , 200 mm / h or more.
For example, when the drainage capacity of the downspout 100 is 190 mm / h, the drainage capacity of the overflow gutter 200 is at least 10 mm / h or more. The drainage capacity of the overflow gutter 200 is preferably set to 50 mm / h or more. That is, since the rainfall of 50 mm / h is a level at which a disaster such as a landslide occurs, if the overflow gutter 200 has a drainage capacity of 50 mm / h or more, it is assumed that all the downspouts 100 are clogged. In the case of normal rainfall, the eaves gutter 10 can be prevented from overflowing.

(Effects of the embodiment)
The effects of the overflow gutter socket 251, the eaves gutter structure A, and the building H of the embodiment are listed below.
(1) By providing the overflow gutter 200 between the eave gutter 10 and the eave ceiling 40 constituting the eaves of the building H, the water can be discharged from the overflow gutter 200 when the water level of the eave gutter 10 rises. Therefore, overflow of the eaves gutter 10 can be prevented. In addition, it is possible to notify the resident of the function deterioration of the eaves gutter 10 due to the discharge from the overflow gutter 200. By configuring the overflow gutter 200 with the upper vertical pipe 210 and the lower vertical pipe 220, it is possible to easily construct the overflow gutter 200. In addition, it is possible to easily allow the mounting positions of the upper vertical pipe 210 and the lower vertical pipe 220 in the horizontal direction and the axial direction (vertical direction) to be easily allowed, and furthermore, it is possible to prevent water leakage.
In the overflow gutter socket 251 of this embodiment, the lower vertical pipe 220 (the pipe main body 221) may be the socket main body 252 into which the upper vertical pipe 210 (the small diameter pipe portion 211b) can be inserted. Thereby, a new function can be added to the overflow gutter 200 only by devising the shape of the lower vertical pipe 220. Alternatively, the overflow gutter 200 can be configured to be easily improved. Therefore, a new function can be easily and inexpensively added without changing the design of the entire overflow gutter 200, and a new function is added later to the existing overflow gutter 200 by replacing the lower vertical pipe 220. It becomes possible.

(2) In the overflow gutter socket 251 of this embodiment, the lower vertical pipe 220 may have corner portions 253 and 254 at a lower portion (such as the flange 222). Accordingly, when the lower vertical pipe 220 is attached to the eaves ceiling 40, it is possible to restrict the unnecessary rotation of the lower vertical pipe 220 by the corners 253 and 254. Therefore, the lower vertical pipe 220 can be easily attached to the eave ceiling 40.
More specifically, for example, when the drain member 230 is screwed and fixed to the lower part of the lower vertical pipe 220, the lower corners 253 and 254 of the lower vertical pipe 220 are external members (for example, eaves). The lower vertical pipe 220 and the drain member 230 are restricted by the rotation of the lower vertical pipe 220 by being hit or caught on the rising portion 40a of the ceiling 40, the eaves receiving material 41, the bracket 41b, etc. (FIG. 8B). Can be prevented from rotating together. Therefore, insufficient tightening due to co-rotation can be solved.

  (3) In the overflow gutter socket 251 of this embodiment, the lower vertical pipe 220 may have a cutout 256 at the upper part (of the pipe main body 221). Thus, in the event that rainwater overflows from the lower vertical pipe 220, the position where rainwater first overflows can be preset by the cutout portion 256. Thus, if the notch 256 is provided on the eaves side, rainwater can be intentionally overflowed from the eaves side. Therefore, it is less likely that the rainwater will inadvertently overflow from the eaves base side, so that it is difficult for the rainwater to flow into the eaves base side or the living room side.

  (4) In the overflow gutter socket 251 of this embodiment, the lower vertical pipe 220 may have a partition 258 inside the pipe main body 221. This prevents the turbulent flow of rainwater from occurring inside the lower vertical pipe 220 by the partition 258, so that drainage (from the drain port 234) can be performed smoothly.

(5) The eaves gutter structure A of this embodiment is attached along the eaves of the building H and drains through the downspouts 100, and the eaves ceiling below the eaves at a position below the eaves gutter 10. And an overflow gutter 200 having a dropout 213 (opening 213a) above the bottom plate 11 forming the bottom surface of the eaves gutter 10 and having a drainage outlet 234 on the lower surface of the eaves ceiling 40. Have been.
Therefore, when the water level of the eaves gutter 10 rises, the water is drained from the drainage port 234 of the eaves ceiling 40 via the overflow gutter 200, and the overflow from the eaves gutter 10 is suppressed, and the ingress of the eaves gutter 40 is suppressed. it can.
Since the overflow gutter 200 may be provided between the eaves gutter 10 and the eaves ceiling 40, the overflow gutter 200 can be formed at lower cost and the appearance quality can be improved as compared with the case where many downspouts 100 are provided.
In addition, the drainage from the drainage port 234 arranged in the eaves ceiling 40 can notify the resident of the decrease in drainage performance of the downspout 100 due to clogging of dust or the like before overflow occurs.
In particular, in this embodiment, a side opening 234a and a lower opening 234b are provided as the drain port 234. Thus, the drainage from the side opening 234a is scattered in the horizontal direction, so that it is possible to more reliably notify the resident of the occurrence of the drainage from the drainage port 234. On the other hand, by providing the lower opening 234b, excessive scattering in the horizontal direction from the side opening 234a can be suppressed, and the scattering of drainage to an adjacent land or the like can be suppressed.

(6) In the eaves gutter structure A of this embodiment, the overflow gutter 200 includes an upper vertical pipe 210 attached to the eaves gutter 10 and a lower vertical pipe 220 attached to the eaves ceiling 40. The upper end of 220 has a larger diameter than the lower end of upper vertical pipe 210, and the lower end of upper vertical pipe 210 is inserted into the upper end of lower vertical pipe 220.
Therefore, even if the horizontal and axial mounting positions of the upper vertical pipe 210 attached to the eaves gutter 10 and the lower vertical pipe 220 attached to the eaves ceiling 40 are misaligned, the difference in radius between the two and the allowance for insertion may be lost. Since only deviation can be tolerated, the workability is excellent and water leakage hardly occurs.
The water leakage suppression performance may be further enhanced by providing a cover or the like that covers a gap between the upper end of the lower vertical pipe 220 and the lower end of the upper vertical pipe 210.

(7) In the eaves gutter structure A of this embodiment, the lower vertical pipe 220 is connected to the drain member 230 having the drain port 234 and is fixed to the eaves ceiling 40.
Therefore, compared with the case where a drain port is provided directly in the lower vertical pipe 220 and this is opened in the eaves ceiling 40, the position adjustment of the drain port, that is, the adjustment of the mounting position of the lower vertical pipe 220 is unnecessary, Excellent workability and excellent appearance quality.

(8) In the eaves gutter structure A of this embodiment, the overflow gutter 200 is provided at a position above the eaves gutter 10 on the water.
Therefore, when the garbage 60 such as dead leaves enters the eaves gutter 10, the garbage 60 easily flows under water and hardly accumulates around the overflow gutter 200, so that the drainage performance of the overflow gutter 200 can be secured.

(9) In the eaves gutter structure A of this embodiment, a gap 244 that covers the upper part of the overflow gutter 200 above the outlet 213 and forms a flow path to the outlet 213 is formed between the overflow gutter 200 and the overflow gutter 200. A lid member 240 to be formed is provided.
Therefore, the lid member 240 prevents the garbage 60 such as dead leaves from directly entering the drop 213 of the overflow gutter 200, and ensures the drainage capacity of the overflow gutter 200. In addition, the presence of the gap 244 can more reliably prevent dust 60 larger than the gap 244 from entering the overflow gutter 200 and clogging the overflow gutter 200.
Note that dust 60 smaller than the gap 244 can be discharged to the outside of the eaves gutter 10 by the overflow gutter 200.
In addition, in the embodiment, since the size of the gap 244 is 1 cm or less and the opening 213a is larger than the gap 244 in the up-down direction and the circumferential direction, in particular, it is possible to prevent dead leaves from blocking the opening 213a. . In addition, the entry of dust 60 such as large dead leaves into the eaves gutter 10 is prevented by the parapet cover 50, so that the dust clogging of the downspout 100 can be suppressed.
