Hereinafter, an embodiment of a relay member for rainwater drainage according to the present invention will be described with reference to the drawings.
First, the configuration of the relay member (rainwater drainage relay member) 1 according to the present embodiment will be described.

As shown in FIG. 1, the relay member 1 is a relay member configured to connect a drainage member 10 configured to allow rainwater to flow in and a vertical gutter 11 piped along an outer wall surface W of a structure. And is interposed between the drainage member 10 and the vertical gutter 11.
The relay member 1 is a square mass for draining rainwater used for large-scale structures and the like, and the drain member 10 connected to the relay member 1 is a horizontally-pulled buried pipe buried in the body of the structure. For example, the tube is made of resin such as vinyl chloride. Although not shown, one end of the drainage member 10 is connected to a drain or the like.

On the other hand, the vertical gutter 11 connected to the relay member 1 is a vertical gutter extending along the outer wall surface W, for example, a pipe made of metal such as stainless steel or aluminum, or a pipe made of resin such as vinyl chloride. Consists of.

Reference numeral O shown in FIG. 1 indicates a central axis line of the downpipe 11, which is hereinafter simply referred to as “axis line O”. In the present embodiment, the direction along the axis O (that is, the vertical direction in FIG. 1) is defined as the “height direction”, and the direction in which the outlet 26 of the relay member 1 is provided (that is, the vertical direction in FIG. 1). The lower side in FIG. 1 is referred to as “down”, and the opposite side (that is, the upper side in FIG. 1) is referred to as “upper”. Further, of the directions orthogonal to the height direction, the direction perpendicular to the outer wall surface W (that is, the lateral direction in FIG. 1) is defined as the “depth direction”, and the outer wall surface W side of the structure (that is, in FIG. 1). The right side is the rear surface (rear surface) and the rear side, and the opposite side (the left side in FIG. 1) is the front surface (front surface) and the front side. Further, of the directions orthogonal to the height direction, the direction along the outer wall surface W, that is, the direction orthogonal to the depth direction (that is, the direction orthogonal to the paper surface of FIG. 1) is referred to as the “width direction”.

The relay member 1 is detachably provided in a main body member 2 formed in a cylindrical shape with a bottom and an opening at the upper end of the main body member 2, and has a through hole 29a that communicates the internal space of the main body member 2 with the outside. And a plate-shaped mounting portion 15 protruding upward from the upper end (upper edge) 24t of the rear wall portion 24 on the outer wall surface W side of the main body member 2 and the width of the mounting portion 15. Vertical grooves 16 extending in the height direction are provided at both ends in the direction.

The main body member 2 is a box-shaped resin member, and is made of a synthetic resin such as hard vinyl chloride, ABS resin, or AES, and is molded by a known resin molding method such as an injection molding method.
It is preferable that the surface layer of the peripheral wall portion 20 is formed of a weather resistant ABS resin or AES resin, and the inner layer is formed of a hard vinyl chloride resin.
The main body member 2 includes a tubular peripheral wall portion 20 extending along the axis O, and a bottom portion 21 provided at a lower end portion of the peripheral wall portion 20.

It is preferable that a large number of them are continuously formed at a pitch of 50 μm or more and 500 μm or less.
By continuously forming such fine grooves, the contact area is reduced with respect to the scratches caused by the contact between the relay members 1 packed in the same box, so that the relay members 1 are not easily scratched. Further, with respect to a scratch caused by contact with another object such as a scaffold or a road surface, since a large number of continuous fine grooves are provided as described above, the contact area with the scaffold or the road surface is reduced and scratches are less likely to occur.
Here, if the depth of the groove is less than 5 μm, the effect of scratches cannot be obtained because the groove is shallow. On the other hand, if the depth of the groove exceeds 100 μm, the effect on scratches can be seen, but the appearance is uncomfortable, which is not preferable.
If the pitch between the grooves is less than 50 μm, the pitch between the grooves is narrow, so the pitch of the convex portions between the grooves is narrow and the number of convex portions per unit length is large. Since the proportion of the convex portion on the surface of the relay member 1 increases, the effect of reducing the contact area becomes poor. On the other hand, when the pitch between the grooves exceeds 500 μm, the pitch of the convex portions between the grooves becomes wide and the number of convex portions per unit length decreases, but the depth of the groove is as described above. Since the depth is set to be 5 μm or more and 50 μm or less, the angle of the apex of the convex portion between the grooves becomes gentle, and when an object is pressed against the surface of the relay member 1, one convex portion The substantial contact area of the top becomes large, and as a result, the effect of reducing the contact area becomes poor.

Further, it is preferable that the convex portion between the grooves on the surface has a shape having a sharp apex or a shape having a rounded apex.
Further, it is preferable that the convex portion forming the groove is made of weather resistant AES resin or ABS resin.

It is to be noted that a groove continuously formed in a direction substantially parallel to the axis O and having a depth of 5 μm or more and 100 μm or less and a plurality of grooves continuously formed at a pitch of 50 μm or more and 500 μm or less in a direction orthogonal to the direction of the axis O is also provided in the downpipe 11. Is preferably provided. As a result, it is possible to prevent the vertical gutter 11 itself from being scratched or dirty, and the same groove pattern as that of the relay member 1 provides a sense of unity in appearance.

It is preferable to select the position of the gate to be injected. That is, in the present embodiment, it is preferable that the weld line is formed on the rear wall portion 24 on the outer wall portion W side. In particular, when a groove that is continuous in a direction substantially parallel to the axis O is formed in the front wall portion 22 and the side wall portion 23, if this groove and the weld line are on the same surface, a regular groove pattern will form the weld line. Since it is disturbed and the appearance is significantly deteriorated, it is preferable to set the gate at a position where a weld line cannot be formed on the front wall portion 22 and the side wall portion 23. The position of the gate for injecting the molten resin into the mold is as shown in FIG.
G1... Inner surface of the outlet port 26, a portion farthest from the rear wall portion G2... Outer surface of the outlet port 26, and portion farthest from the rear wall portion 24 G3... Outer surface of the bottom portion 31, and The three locations farthest from the rear wall portion 24 are candidates. Since all of G1, G2, and G3 described above are located on the lower side of the peripheral wall portion 20, when the relay member 1 is assembled to the drainage member 10 and the vertical gutter 11 and installed on the outer wall surface W, the injection member is completed after the resin injection is completed. Is formed by being extracted from the molded body, and the gate marks remaining in a convex shape are in a position where it is difficult to see from the front, which is good in terms of appearance.
When the position of the gate is set to G1, when the gutter 11 is fitted on the outflow port 26 and connected, the connection can be made without interfering with the convex portion of the gate mark.
When the position of the gate is G3, the convex portion may be visible from below, but when the position of the gate is G2, the gate mark is located on the outer surface of the outlet 26, so The external fitting makes it invisible from the front and bottom.

As described above, according to the relay member 1 of the present embodiment, the rainwater that has flowed from the outer wall surface W of the structure to be mounted and has flowed to the upper portion of the relay member 1 reaches the upper surface 15a of the mounting portion 15, As shown in FIG. 4, it flows to both sides of the mounting portion 15 in the width direction and flows into the vertical groove 16. Since the lower end 16b of the vertical groove 16 is connected to the upper surface 29b of the lid body 29, the rainwater that has flowed into the vertical groove 16 is collected on the upper surface 29b of the lid body 29, and the flow passage space of the main body member 2 from the through hole 29a. Eventually, it flows out into the vertical gutter 11 through S1. Therefore, the rainwater that has flowed to the upper end of the relay member 1, that is, the upper surface 15a of the mounting portion 15, does not overflow to the side surface of the main body member 2, that is, the peripheral wall portion 20, and smoothly flows into the flow passage space S1 of the main body member 2. And, it flows into the vertical gutter 11 and is drained. As a result, it is possible to prevent rainwater that has reached the upper surface 15a of the mounting portion 15 from flowing down along the outer wall surface W on the side of the main body member 2. Then, due to the rainwater that has flowed from the outer wall surface W of the structure and the like and has flowed to the upper surface 15a of the mounting portion 15 of the relay member 1 and the dirt attached to the surface of the relay member 1, the outer wall surface W of the structure is It can be prevented from becoming dirty.

In the relay member 1 of the present embodiment, a guide wall 18 that is continuous with the vertical groove 16 is provided, and the guide wall 18 extends from the upper surface 15a of the mounting portion 15 to the upper surface 2a of the main body member 2 and further to the upper surface 29b of the lid 29. Since the inclined surface 18p is inclined toward the vertical groove 16, even when rainwater has a momentum toward the outer side in the width direction of the mounting portion 15 when flowing into the vertical groove 16, the momentum can be absorbed and reduced by the inclined surface 18p. .. As a result, the rainwater that has flowed to the upper surface 15a of the mounting portion 15 does not overflow into the peripheral wall portion 20 of the main body member 2 more smoothly and reliably, and the flow passage space S1 of the main body member 2 and the vertical gutter 11 are provided. Can be flowed inside.

In the relay member 1 of the present embodiment, since the concave portion 19 that gradually lowers toward the center in the width direction is formed on the upper surface 15a of the mounting portion 15, a portion of the rainwater flowing on the upper surface 15a of the mounting portion 15 is removed. The recesses 19 collect the water on the center side of the upper surface 15a in the width direction, and efficiently collect water on the upper surface 29b of the lid 29 from the bottom end of the recess 19 through the surface opposite to the outer wall surface W of the mounting portion 15. You can In this way, since the rainwater that has flowed to the upper surface 15a of the mounting portion 15 is collected by both the vertical groove 16 and the concave portion 19, the rainwater does not overflow to the peripheral wall portion 20 of the main body member 2 and can be made smoother and more reliable. In addition, it can be made to flow into the flow passage space S1 of the main body member 2 and the inside of the vertical gutter 11.

Further, since the relay member 1 of the present embodiment includes the spacer 3, even when the dimension in which the drainage member 10 projects from the outer wall surface W is larger than the dimension of the main body member 2, the outer wall surface W is formed. By interposing the spacer 3 between the main body member 2 and the main body member 2, the main body member 2 can be stably installed on the outer wall surface W. Thereby, the posture of the main body member 2 can be more accurately fixed to the outer wall surface W. Therefore, it is possible to prevent the rainwater from leaking due to the posture deviation of the main body member 2 and the occurrence of a defective connection with the drain member 10 and the downpipe 11. Further, even if the dimension in which the drainage member 10 projects from the outer wall surface W changes, if the depth dimension of the spacer is adjusted to manufacture and use it, it is necessary to change the dimensions of each part of the main body member 2 and remanufacture. There is no. That is, the shape and size of the main body member 2 can be used in common regardless of the size of the drain member 10 protruding from the outer wall surface W, and the manufacturing cost of the relay member 1 can be reduced.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be appropriately modified without departing from the gist thereof.

For example, the guide wall 18 may be omitted if necessary, and more rainwater can be introduced into the groove by adjusting the depth (depth in the depth direction) of the vertical groove 16 or the like.

Further, for example, as shown in FIG. 7, the guide wall 18 may be provided with the step portion 17 over the entire lengthwise direction (that is, the depth direction) of the inner edge end of the slope 18p. The step portion 17 may have multiple steps. The step portion 17 may be provided only on the upper surface 15a side of the mounting portion 15.

As described above, by providing the step portion 17 on the guide wall 18, the rainwater flowing on the upper surface 15a of the attachment portion 15 can be guided to the inside of the guide wall 18. As a result, rainwater can more easily flow into the vertical gutter 11 through the vertical groove 16 communicating with the step portion 17.

Further, as a modified example of the spacer 3 illustrated in FIG. 6 and the like, for example, the spacer 46 illustrated in FIG. 8 may be used. The spacer 46 includes an upper portion 47 having the same shape as the upper portion 38 of the spacer 3, and a fitting portion 48 provided so as to project downward from the bottom surface of the upper portion 47. A concave portion 49 that is convex downward is provided on the center side in the width direction of the upper portion 47. As shown in FIGS. 8 and 9, the fitting portion 48 is configured to be externally fitted to a fixture 55 (for example, a screw or the like) that couples the main body member 2 and the structure, and the connector 55 is inserted therethrough. It has a possible hollow portion 48s and an abutting portion 48g having a gap communicating with the hollow portion 48s and formed in an arc shape in a sectional view so as to come into contact with the outer peripheral surface of the tool 55.

As shown in FIG. 8, if the spacer 46 is preliminarily made long in parallel with the extending direction L of the fitting portion 48, the distance between the mounting portion 15 of the main body member 2 and the outer wall surface W (FIG. 9). The length dimension l46 can be cut out from the long spacer 46 along the extending direction L in accordance with the above (see (4)). When attaching the spacer 46, the fixture 55 is first passed through the attachment hole 28A of the attachment portion 15 from the front side, and the tip of the fixture 55 is embedded in the structure. Next, the fitting portion 48 of the spacer 46 cut out with the length dimension l46 is externally fitted to the exposed portion of the fixture 55 from above to complete the attachment.

Even with the spacer 46 having the above-described configuration, even when the dimension in which the drainage member 10 projects from the outer wall surface W is larger than the dimension of the main body member 2, the space between the outer wall surface W and the main body member 2 is increased. The body member 2 can be stably installed on the outer wall surface W with the spacer 46 interposed. Therefore, the same operational effect as when the spacer 3 is used can be obtained. Further, even if the distance between the mounting portion 15 of the main body member 2 and the outer wall surface W is changed, the manufacturing process and the work are complicated because the spacer 46 formed in a long size is cut out and used with an arbitrary length dimension l46. The main body member 2 can be stably installed on the outer wall surface W without being converted.
