Description

  The present invention includes a spigot attached to an opening provided on the side wall from one side of the side wall of the circular pipe, and a socket attached to the opening from the other side of the side wall. The outer periphery of the mouth is a branch pipe connection port including a stepped portion whose diameter is larger than the outer diameter of the region other than the vicinity of the root of the spigot flange in the region near the root of the spigot flange, and rainwater including the branch connection port. About.

  In addition, the present invention provides a rainwater tank having the above-mentioned branch pipe connection port, and is detachably accommodated in the rising part, the bottomed mud reservoir part connected to the lower part of the rising part, and the mud reservoir part. Rainwater trough or rainwater infiltrate with a bucket (hereinafter collectively referred to simply as “rainwater trough”), especially for placing the bucket in place in the mud pool Including a storm drain having a bucket guide fixed between the riser and the mud pool.

  In general, rainwater that falls on the roof of a building is collected by rainwater in a residential area. Rainwater may contain foreign matter such as mud and dead leaves. For this reason, as described in, for example, JP-A-8-86007 (Patent Document 1) and JP-A-2013-19218 (Patent Document 2), foreign matters such as mud do not flow out of the rainwater. In addition, a bottomed mud reservoir is provided at the bottom of the main body to capture foreign matter, and a mud reservoir (bucket) is detachably attached to the mud reservoir. It has been known. As described above, the rainwater mass is a main body having a plurality of drain pipe connection ports in a predetermined direction, a mud reservoir attached to the lower part thereof, and a mud reservoir attached to the mud reservoir. It has the characteristic of having a complicated structure and shape with the container as the main component.

  On the other hand, in recent years, with the popularization of rainwater, there is a demand for rainwater that is suitable for various installation locations, installation environments, and usage methods. However, in the case of the above-described highly functional rainwater, there has been a problem that manufacturing costs will increase if various types of rainwater are molded according to the installation location.

  For this reason, by expanding the use of general-purpose products, it is conceivable to reduce the number of parts of dedicated products and provide low-cost rainwater while maintaining high functionality. For example, for a main body having a plurality of drain pipe connection ports, a general-purpose circular pipe is used instead of the main body, and for a drain pipe connection port, Japanese Patent Laid-Open No. 2000-8475 (Patent Document 3) It is considered that a general-purpose connection port is retrofitted to an opening provided in a general-purpose circular tube by using a connection port retrofit technique as described in JP-A-2006-266075 (Patent Document 4). It is done. In addition, the mud reservoir and the bucket attached to the lower part of the general-purpose circular pipe were limited by adjusting to the general-purpose circular pipe size (standard) in order to maintain the high function of capturing foreign matter in the drainage. It is conceivable to produce only special types (sizes).

  As mentioned above, when combining a general-purpose circular pipe and a general-purpose connection port with a dedicated mud reservoir and bucket, expand the use of general-purpose products for various installation locations, installation environments, and usage methods. In addition, by adjusting to the standard (size) of general-purpose products, it is possible to reduce the number of dedicated products that must be manufactured, so it is possible to provide low-cost rainwater while maintaining high functionality. . In addition, the drain pipe connection ports can be attached to any position (height, direction) of a general-purpose circular pipe in any direction according to the position of the drain pipe at the construction site. The use of general-purpose products can be expanded for various installation locations, installation environments, and usage methods without increasing the number of parts.

  However, in the case of rainwater, if a general-purpose circular pipe and a general-purpose connection port are used instead of the main body, and a mud reservoir is provided at the bottom of the general-purpose circular pipe, a bucket will be described below. It was found that such a problem occurred.

[First problem]
When the main body, which is a dedicated product, is replaced with a general-purpose circular tube, the connection port of the drainage pipe is provided with an opening in the peripheral wall of the circular tube and the general-purpose connection port is retrofitted. For this reason, the opening provided on the peripheral wall of the circular tube using a hole saw or the like is opened slightly larger than the outer diameter of the connection port inserted into the opening in consideration of smooth insertion.

  However, when the opening of the circular pipe is larger than the outer diameter of the connection port, there is a problem that a gap is formed between the opening and the insertion port, resulting in a decrease in the water stoppage of the connection port mounting portion. . In addition, it is conceivable to arrange packing etc. at the insertion port of the connection port, but in this case, the number of parts increases, the shape of the insertion port for fixing packing etc. becomes complicated, and the connection port attached later There was a problem that the rainwater used was expensive. In addition, in the case of rainwater that is attached to the bucket using the irregularities of the flange of the connection port inside the drainage basin, the connection port generates a misalignment (backlash) with respect to the opening of the circular pipe, There was also a problem that the bucket could not be installed at an appropriate position in the rainwater.

[Second problem]
Next, the bucket attached to the mud pool reliably captures rainwater and foreign substances contained in the rain water, and maintains a certain gap between the bucket and the mud pool. It is necessary to maintain the drainage (penetration) of rainwater, etc., and make it easy to put in and out the bucket from the upper inspection port. For this reason, the bucket must be mounted so that a certain clearance is formed between the bucket and the central axis of the bucket and the central axis of the rainwater are aligned. For this reason, in conventional rainwater mass, since the main body is increasingly a dedicated product, a ring-shaped guide for guiding the mounting position of the bucket is provided on the inner wall surface of the main body (Patent Documents 1 and 2). ).

  The ring-shaped guide fills the gap between the side wall of the bucket and the side wall of the rainwater, so that the foreign material does not accumulate on the upper part of the guide as close to the upper edge of the bucket as possible. It is desirable to arrange so that it contacts.

  However, if the main body of the special product is replaced with a general-purpose circular pipe, it will not be possible to provide a ring-shaped guide in advance on the inner wall surface of the circular pipe. There has been a problem that it is impossible to arrange them so that the axes coincide with each other. In addition, a general-purpose circular pipe is cut to an appropriate length at the construction site, and a general-purpose connection port is attached to the peripheral wall of the circular pipe at an arbitrary position. There has been a problem that a ring-shaped guide cannot be provided in advance on the inner wall surface of the tube.

  It is also conceivable to provide a ring-shaped guide for guiding the bucket on the inner wall surface of the mud reservoir or the upper edge of the bucket itself. However, in the former case, the height of the wall of the mud reservoir must be equal to or higher than the height of the bucket, so the total height of the rainwater is high (the total length is long), and the ground, etc. It is necessary to dig deeper and embed rainwater deeply, or conversely, the height of the general-purpose circular pipe is low (short), and the drainage pipe connection port is free of the general-purpose circular pipe There was a problem that it could not be mounted at a proper position (height, direction). In the latter case, there is a problem that the bucket cannot be smoothly inserted and removed from the inspection port.

JP-A-8-86007 JP2013-19218A JP 2000-8475 A JP 2006-266075 A

  Therefore, an object of the present invention is to provide an opening on a side wall of a general-purpose circular pipe connected to the upper portion of the mud reservoir, etc., and a general-purpose connection port is attached to the opening. A branch connection port and its branch connection that prevent the occurrence of core misalignment (gap) between the opening and the opening of the connection port and prevent water leakage from the opening (connecting port attachment part) and improve water stoppage. It is to provide rainwater trout with a mouth.

  Furthermore, another object of the present invention is to provide a rainwater tank having the above-mentioned branch pipe connection port, and a rainwater having a mud reservoir for catching foreign matter in the drainage and a bucket mounted in the mud reservoir. In general, a general-purpose circular pipe can be used as the main body connected to the upper part of the mud reservoir (the part where a plurality of connection ports are provided), yet the bucket is connected to the central axis of the bucket and the center of the rainwater The purpose of the present invention is to provide a rainwater trough that can be mounted in an aligned manner so that the shaft can be easily aligned.

  In order to achieve the above two objects, the present inventors have provided a general-purpose connection port (hereinafter also referred to as a “branch connection port”) attached to an opening provided in a general-purpose circular tube, a general-purpose circular tube, It is arranged on the upper part of the mud reservoir on the premise that it is rainwater with a connection structure and a mud reservoir for catching foreign matter in rainwater and a bucket mounted in the mud reservoir. We have made extensive studies on the connection structure between the riser and the mud reservoir that consist of general-purpose circular pipes. As a result, for the prevention of water leakage at the branch pipe connection port mounting portion, by expanding the predetermined area of the branch pipe connection opening, while using a general-purpose connection port, the branch pipe connection port and the opening of the circular pipe We found that it is possible to effectively prevent core misalignment (backlash) and water leakage from the branch port connection part, and centering the bucket (Make sure that the center axis of the bucket and the center axis of the rainwater are aligned) With respect to the above, it has been found that by providing a bucket guide supported between the rising portion and the mud reservoir, it is possible to center the bucket while using a general-purpose circular tube, and the present invention has been completed. It was.

  That is, according to the present invention, as one embodiment, the branch connection port is attached to the opening provided on the side wall of the circular tube, and the branch connection port includes an insertion port through which the circular tube opening is inserted, and an insertion port. A spigot attached to the side wall on one side of the circular tube, and having a spigot flange secured to the outer periphery and curved along the side wall on one side of the circular tube; The circle having a receptacle fitted to the mouth, and a socket flange fixed to the outer periphery of the receptacle and curved along the side wall on the other side opposite to the one side of the circular tube. A socket attached to the side wall of the other side of the pipe, and in the outer periphery of the spigot, the area near the root of the spigot flange is larger than the outer diameter of the area other than the vicinity of the root of the spigot flange. Branch pipe connecting port is provided, characterized in that it comprises a stepped portion which is radial.

  Moreover, in this invention, a circular pipe may comprise the said rising part of the rainwater trough provided with the rising part which can be cut off, and the mud pool part connected to the lower part of a rising part. Furthermore, the rainwater basin having the above-mentioned branch pipe connection port, a rising portion, a bottomed mud reservoir portion connected to a lower portion of the rising portion, and a bucket detachably accommodated in the mud reservoir portion, A rainwater basin with a bucket guide fixed between the riser and the mud reservoir, especially for placing the bucket in place in the mud reservoir. May be.

  In the present invention, one branch pipe connection port part having a slot is called a spigot, and the other branch pipe connection part having a receptacle is called a socket.

  A branch pipe connection port attached to an opening provided on the side wall of a general-purpose circular pipe such as a rising portion of rainwater trough is a spigot having an insertion hole through which the opening is inserted, and a receiving port fitted to the spigot insertion port The region near the root of the spigot flange on the outer periphery of the spigot outlet is a stepped portion whose diameter is larger than the outer diameter of the region other than the vicinity of the root of the spigot flange. And has substantially the same diameter as the opening provided in the side wall of the circular tube such as the rising portion.

  In addition, the branch pipe connection port of the present invention and the rainwater tank provided with the branch connection port are preferably made of vinyl chloride resin, and in that case, the stepped portion of the spigot outlet having an enlarged diameter (near the root of the spigot flange) Area) is softened by application of an organic solvent adhesive, so the spigot outlet can be formed without creating a gap between the stepped portion of the spigot outlet and the opening of the circular pipe such as the rising portion. Can be easily inserted into and closely attached to the opening of the circular tube such as the rising portion.

Furthermore, in the case of the rainwater tank having the branch pipe connection port according to the present invention, when the bucket is detachably accommodated in the mud reservoir, the flange of the spigot is provided with a groove for fitting the handle of the bucket. A bucket can be attached by providing. In this case, if there is a gap between the spigot slot and the opening of the rising portion, the attachment position of the bucket to the mud reservoir is likely to be displaced or loose. However, in the case of a rainwater basin having a branch pipe connection port according to the present invention, the stepped portion provided at the spigot insertion port allows the spigot to reach the rising portion without causing a gap between the spigot insertion port and the opening of the rising portion. Since it can be attached, there is no deviation or backlash at the attachment position of the bucket to the mud reservoir. Further, since the gap is eliminated, even when the filter and the orifice attached to the bucket are provided, the filter and the orifice are not easily displaced from the outlet.

  As described above, the above-mentioned branch pipe connection port prevents core misalignment (backlash) generated between the opening of the circular pipe such as the rising part while maintaining the high insertion property of the spigot opening, and further the rising part. Thus, it is possible to prevent water leakage from the opening of the circular pipe or the like (attachment part of the branch pipe connection port) and to improve water stoppage. In addition, in order to realize higher insertion of the spigot outlet, the width of the outer peripheral portion (stepped portion) with the enlarged diameter of the spigot outlet is substantially the same as the thickness of the circular pipe such as the rising portion. You can do it. In this case, since the curved socket flange comes into contact with both the stepped portion of the spigot and the side wall of the circular pipe such as the rising portion, there is an effect that it is more difficult to generate a gap in the attachment portion of the branch pipe connection port.

  In the present invention, the spigot and the socket may be attached to either the inner side wall or the outer side wall of the circular pipe such as the rising part, for example, when the spigot is attached to the inner side wall of the circular pipe such as the rising part. , The socket is attached to the outer side wall of the circular pipe such as the rising part on the opposite side, and conversely, when the spigot is attached to the outer side wall of the circular pipe such as the rising part, the socket is attached to the circular pipe such as the rising part on the opposite side. Mounted on the inner sidewall.

  The spigot flange and the socket flange are curved so as to follow the shape of the side wall of the circular tube such as the rising portion. For example, the flange attached to the inner side wall of the circular tube such as the rising portion is curved convexly along the inner side wall. On the other hand, the flange attached to the outer side wall of the circular pipe such as the rising portion is preferably curved in a concave shape along the outer side wall. In addition, the spigot flange and the socket flange do not necessarily have a planar shape, and a combination of a plurality of rod-like members, such as a lattice, can be used as long as the spigot flange and the socket flange can be brought into close contact with the side wall shape of the circular pipe such as the rising portion Or a combination of a rod-shaped member and a planar member.

  In the case where the present invention is a rainwater basin provided with a branch pipe connection port, the branch pipe connection port configured as described above can be freely positioned (height) at the rising portion of the rainwater basin according to the position of the drain pipe at the construction site. , Direction) can be attached in any direction.

  Typically, when the present invention is a rainwater basin having a branch connection port, the branch connection port communicated from the outside to the rainwater basin as an inflow port for allowing rainwater or the like to flow into the stormwater from the outside, and / or Or, as an outlet for draining rainwater etc. from the rainwater mass to the outside, the branch pipe connection port communicating from the rainwater mass to the outside is attached to the free position (height, direction) of the rising part in any direction It is done.

  Furthermore, when the present invention is a rainwater basin provided with a branch pipe connection port, the rainwater basin is composed of a rising portion that can be cut as another form, and a mud pool portion connected to the lower portion of the rising portion. And a predetermined gap between the outer side wall of the bucket and the inner side wall of the mud reservoir when the bucket is mounted in the mud reservoir. When connecting the rising part and the mud reservoir part to the guide part arranged around the outer side wall of the bucket so as to form, it is fixed inside the main body by being sandwiched between the rising part and the mud reservoir part A bucket guide having a hanging portion may be provided.

  In the rainwater tank of the present invention, the bucket guide is configured as an independent part separate from the rising part and the mud reservoir, and can be fixed inside the main body by being sandwiched between the rising part and the mud reservoir. . For this reason, even if the rising portion is a general-purpose circular tube, the general-purpose circular tube can be connected to the upper part of the mud reservoir, and can be used as a main body.

  The bucket guide has a hook portion sandwiched between the rising portion and the mud reservoir portion and a guide portion protruding inward from the bucket guide main body. For this reason, when the bucket is installed in the mud pool, the bucket is aligned with the central axis of the rainwater basin by bringing the outer side wall of the bucket into sliding contact with the guide part. And a predetermined gap is formed between the outer side wall of the bucket and the inner side wall of the mud reservoir.

  The hook part of the bucket guide can be easily sandwiched between the rising part and the mud reservoir part, and the contact area between the rising part and the mud reservoir part is not reduced as much as possible. It is preferable that it is a flange shape which can contact | abut with the upper end surface of an end surface and / or a mud reservoir part side wall. For this reason, when either one of the lower part of the rising part side wall or the upper part of the mud reservoir side wall is an outlet, and one of the upper part of the mud part side wall or the lower part of the rising part side wall is a receptacle, A flange shape capable of abutting against the stepped portion of the receiving port with which the end surface of the abutting member abuts may be used.

  The guide part of the bucket guide has a guide surface that slidably contacts the outer side wall of the bucket to guide the bucket to the exact position in the rainwater (mud part) when the bucket is installed in the mud part. It is preferable to have.

  For this reason, it is preferable that the guide part of the bucket guide has a ring shape extending in the circumferential direction of the main body or a plurality of tongues extending in the radial direction of the main body. If the guide part of the bucket is composed of a ring or a plurality of tongues extending in the radial direction of the main body, the bucket can be rained because the outer side wall of the bucket can be slidably supported from almost all directions. It is guided to a more accurate position in the (mud reservoir), and a predetermined gap is stably formed between the outer side wall of the bucket and the inner side wall of the mud reservoir.

  The guide portion of the bucket guide is preferably arranged so as to abut on the vicinity of the upper edge of the bucket as much as possible so that foreign matter does not accumulate on the upper portion of the guide portion, while the hook portion of the bucket guide is generally It is preferable to arrange in the vicinity of the upper end surface of the mud reservoir side wall and / or the lower end surface of the rising portion side wall lower than the bucket.

  For this reason, the guide part and the hook part of the bucket guide are often arranged apart from each other in the height direction, and for this reason, the guide part of the bucket guide is viewed in cross section so as to be connected to the spaced hook part. , It is preferable to have a U-shaped cross-sectional shape downward or a U-shaped cross-sectional shape downward. Further, if the cross-sectional shape of the guide portion of the bucket guide is a downward U-shape or a downward U-shape, the cross-section coefficient of the guide portion also increases, so there is an advantage that the rigidity of the entire bucket guide can be increased. .

  The mud reservoir has a plurality of water permeable holes or a plurality of water permeable slits on the side wall of the mud dam, and the bucket has a water permeable hole or a water permeable water in the mud pit when the bucket is mounted in the mud reservoir. Among the slits, it is preferable to have a plurality of through holes or a plurality of through slits arranged at a position higher than the upper end of the water permeable hole at the highest position or the upper end of the water permeable slit.

  In the rainwater basin of the present invention, a bottomed cylindrical mud reservoir having a plurality of water-permeable holes and the like is provided on the side wall so as to surround the bucket. A bucket is detachably attached to the. Rainwater containing foreign matter such as mud and dead leaves that flow in through the branch connection port flows into the bucket, but since there is no through hole in the lower area of the bucket, rainwater that flows into the bucket The foreign matter that once stays in the lower region and is contained in rainwater or the like accumulates in the lower region in the bucket. And when rainwater etc. accumulates in the bucket, only the supernatant liquid such as rainwater staying in the bucket is discharged to the outside of the bucket through the through hole etc. provided in the upper region of the bucket and discharged to the outside of the bucket The supernatant liquid such as rainwater is then drained to the outside of the mud pool through the water-permeable holes provided in the mud pool.

  For this reason, if a plurality of holes are provided on the side wall of the mud reservoir as described above and a plurality of through holes are provided on the bucket at a position higher than the water holes of the mud reservoir, the rainwater is infiltrated. Even if it functions as much as possible, foreign substances contained in rainwater, etc. will remain in the lower area of the bucket, so the foreign objects will rain, so they will not flow out to the quarry tank spread outside the rainwater. The crushing of the lithotrip tank is prevented.

  Further, since the bucket mounted in the mud reservoir is detachable as described above, when removing the accumulated foreign matter, the bucket is further removed from the main body and the foreign matter in the bucket is discarded. Since it can be done with simple work, the maintenance of rainwater is improved.

  Since the branch pipe connection port of the present invention has an expanded spigot insertion port (region near the root of the spigot flange), the spigot insertion port is located between the spigot insertion port and the opening of the circular pipe such as a rising portion. Without causing a gap, the spigot slot can be easily inserted into and closely attached to the opening of the circular pipe such as the rising part. As a result, the branch pipe connection port of the present invention prevents core misalignment (rattle) that occurs between the opening of the circular tube such as the rising portion while maintaining high insertion of the spigot insertion port, and further the rising portion. It is possible to effectively prevent water leakage from the opening of the circular pipe or the like.

  When the present invention is a rainwater tank having a branch pipe connection port, the branch pipe connection port of the present invention has a spigot with a spigot and a socket with a receiving port fitted to the spigot spigot. Because it can be retrofitted to an opening provided in a circular pipe such as a rising part of rainwater, any position (height, direction) of the circular pipe such as a rising part can be set according to the position of the drain pipe at the construction site. A plurality can be attached in the direction. For this reason, the branch pipe connection port of the present invention is not limited to a circular pipe used as a rising portion in rainwater, but can be basically used for other general-purpose circular pipes.

  When the present invention is a rainwater trough with a branch pipe connection port, in order to catch foreign matter such as mud and dead leaves contained in the rainwater, a bottomed mud reservoir and a mud reservoir It can be a highly functional rainwater can with a bucket removably mounted inside. Nevertheless, the rainwater basin of the present invention can use a general-purpose circular pipe at the rising portion, and the bucket guide can be supported at the connecting portion between the rising portion and the mud reservoir. When installed in the reservoir, the bucket is guided by the bucket guide so that the central axis of the bucket coincides with the central axis of the rainwater and between the outer side wall of the bucket and the inner side wall of the mud reservoir. A predetermined gap is formed.

  In the case where the present invention is a rainwater trough having a branch pipe connection port, a plurality of water permeable holes are provided on the side wall of the mud reservoir, and the bucket is provided with a plurality of holes at a position higher than the water permeable holes of the mud reservoir. Since the through-holes are provided, it can also function as rainwater can penetrate, and foreign matter contained in rainwater etc. will remain in the lower area in the bucket, so foreign matter will rain. The crushing of the crushed stone tank can be prevented since it does not flow out toward the crushed stone tank spread on the outside.

  When the present invention is a rainwater trough having a branch pipe connection port, a general-purpose circular pipe and an improved general-purpose connection port other than a mud reservoir and a bucket that is detachably mounted in the mud reservoir Since it is used as a part and branch pipe connection port, it is possible to provide low-cost rainwater while maintaining high functionality.

It is sectional drawing which shows embodiment of the other rainwater mass provided with the branch pipe connection port of this invention.

  Hereinafter, a branch pipe connection port according to an embodiment of the present invention and a rainwater trough provided with the branch connection port will be described in detail with reference to the drawings. The present invention is not limited to the examples shown below, and various modifications can be made without departing from the technical idea of the present invention.

  The main structure of the rainwater trough 1 provided with the branch pipe connection port 7 which concerns on one Embodiment of this invention and this branch pipe connection port 7 is demonstrated using FIGS. 1-3. FIG. 1 shows a branch pipe connection port 7 according to the present embodiment and a perspective view seen from above a rainwater trough 1 provided with the branch pipe connection port 7. FIG. 2 shows a perspective view of the branch pipe connection port 7 shown in FIG. 1 and a state in which the rainwater trough 1 having the branch pipe connection port 7 is disassembled. FIG. 3 is a cross-sectional view of the branch pipe connection port 7 of the present embodiment shown in FIG. 1 and a rainwater trough 1 having the branch connection port 7 cut along the AA cross section.

  As can be understood with reference to FIGS. 1 to 3, the rainwater masu 1 of this embodiment is composed of a cylindrical rising portion 3 and a mud reservoir 4 connected to the lower portion of the rising portion 3. And a bucket 5 detachably accommodated in the mud reservoir 4, a bucket guide 6 fixed to a connecting portion between the rising portion 3 and the mud reservoir 4, and a side wall of the rising portion 3. Two branch pipe connection ports 7 are provided, and are made of vinyl chloride resin in consideration of the moldability and ease of handling of these parts.

  The rising portion 3 can be cut to an arbitrary height (length) in order to adjust the height of the rainwater mass 1, and a standardized general-purpose circular tube can be used. For this reason, the rainwater trough 1 of this embodiment can be installed in the installation site of various depth according to an installation environment in a construction site.

  A dedicated mud reservoir 4 is connected below the rising portion 3 with a bucket guide 6 to be described later interposed therebetween. The mud reservoir 4 is a bottomed tubular body, and the upper end of the mud reservoir 4 receives the lower end of the rising portion 3, so that a receiving port 40 having an inner diameter substantially the same as the outer diameter of the rising portion 3 is provided. Is formed. For this reason, the mud reservoir 4 of the present embodiment is a dedicated part for rainwater 1 but it is sufficient to prepare the mud reservoir 4 having the number of receiving ports 40 corresponding to the standard of the rising part 3, The number of types of mud reservoirs 4 that must be reduced can be reduced.

  The bucket 5 accommodated in the mud reservoir 4 is a bottomed cylindrical body, and has an outer diameter smaller than the inner diameter of the mud reservoir 4 in order to discharge rainwater retained in the bucket 5 to the mud reservoir 4. And a gap is formed between the mud reservoir 4. Further, as shown in FIG. 2, the bucket 5 of the present embodiment includes a handle 50 integrally formed at the upper end portion of the bucket 5 in order to facilitate taking in and out from the upper inspection port 20. Yes.

  Further, as shown in FIG. 3, the opening position of the bucket 5 (the height of the upper opening edge) is a region located on the branch pipe connection port 7 on the rainwater inflow side (left side as viewed in FIG. 3) and rainwater. The height of each opening position (upper opening edge) of the region (right side in FIG. 3) located in the branch pipe connection port 7 on the outflow side is different. In other words, in this embodiment, the opening position (upper opening edge) of the bucket 5 on the rainwater inlet side is set lower than the opening position (upper opening edge) of the bucket 5 on the rainwater outlet side.

  As described above, when the opening position (upper opening edge) of the bucket 5 on the rainwater inflow side is made lower than the opening position (upper opening edge) of the bucket 5 on the rainwater outflow side, the branch pipe connection port 7 on the rainwater inflow side Even when a flange is provided on the internal branch pipe connection port component 70, interference between the flange and the opening position (upper opening edge) of the bucket 5 can be avoided, so that the internal branch pipe connection port component 70 can be attached. It becomes easy, and even the internal branch pipe connection port component 70 having flanges of various shapes and sizes can be attached. In addition, the opening position (upper opening edge) of the bucket 5 facing the rainwater inlet is lowered, and the opening position (upper opening edge) of the bucket 5 on the side where the inflowing rainwater collides is increased, so that the rainwater becomes smoother. The effect of being guided into the bucket 5 is also achieved.

  The handle 50 has a downward U-shape, a filter support 51 that is detachably attached to the vertical member of the handle 50, and a dome-shaped filter made of a wire mesh that is attached to the filter support 51 in a replaceable manner. 52. A semi-arc-shaped flange protruding outward in a substantially horizontal direction is formed at the opening position (upper opening edge) of the bucket 5 located between the two roots of the handle 50 (FIG. 2). When the support part 51 is inserted by sliding downward from the upper part of the handle 50, the flange functions as a stopper, and the lower end part of the filter support part 51 abuts against the flange on the upper part of the bucket 5, thereby supporting the filter. The part 51 and the filter 52 are accurately fixed to a predetermined position of the handle 50.

  A ring-shaped bucket guide 6 is attached between the rising portion 3 and the mud reservoir portion 4. As can be understood with reference to FIG. 4, the bucket guide 6 is configured as a separate part independent of the rising portion 3 and the mud reservoir 4, and when the bucket 5 is mounted in the mud reservoir 4. , A guide part 60 for guiding the bucket 5 to a predetermined position in the mud reservoir part 4, a hook part 61 for fixing the bucket guide 6 to the main body 2, and a guide part 60 and the hook part 61. And a connecting portion 62 connected to each other.

  FIG. 4 shows a top view and a side view of the bucket guide 6. The guide portion 60 of the bucket guide 6 is disposed so as to be able to surround the outer side wall of the bucket 5, and has a guide surface 63 that slidably contacts the outer side wall of the bucket 5. The guide surface 63 may be a cylindrical surface or a linear surface arranged substantially parallel to the outer side wall of the bucket 5 when the bucket 5 is mounted in the mud reservoir 4, or the bucket is directed downward. The surface may be inclined so as to approach the outer side wall 5 (so that the diameter decreases toward the lower side).

  In this embodiment, in order to guide the bucket 5 to a predetermined position in the mud reservoir 4, the guide surface 63 of the guide unit 60 approaches the outer side wall of the bucket 5 as it goes downward (downward). Inclined first guide surface 64 and a cylindrical shape disposed substantially parallel to the outer side wall of the bucket 5 in order to hold the bucket 5 in a predetermined position in the mud reservoir 4. The second guide surface 65 is included. In addition, although not shown, the second guide surface 65 may have an inclined surface that is reduced in diameter in the direction in which the bucket 5 is inserted, similarly to the first guide surface 64. In this case, the bucket 5 can be easily inserted and removed.

  The guide portion 60 of the bucket guide 6 only needs to have a shape that can restrain the bucket 5 mounted in the mud reservoir portion 4 from the outside, so that as shown in FIGS. In order to give flexibility to deformation in the circumferential direction in addition to the ring shape extending in the direction, for example, a slit (slit) is provided in a part of the ring-shaped bucket guide extending in the circumferential direction, or for example, It can also be comprised from the several tongue part extended in the radial direction of the main body 2 (not shown). When the guide part 60 is composed of a plurality of tongues, the bucket 5 can be restrained if it can be supported from at least three directions. In this case, the tongues are spaced 120 ° apart in the circumferential direction. It is preferable that they are arranged evenly in the circumferential direction.

  For this reason, when the bucket 5 is mounted into the mud reservoir 4 via the bucket guide 6, the outer side wall of the bucket 5 is slidably guided by the guide surface 63 of the guide portion 60. The central axis X of the rainwater and the central axis Y of the rainwater 1 are guided so that a predetermined gap is stably formed between the outer side wall of the bucket 5 and the inner side wall of the mud reservoir 4. (See FIG. 3).

  The hook portion 61 of the bucket guide 6 has a flange shape that protrudes outward from the connecting portion 62, and when the rising portion 3 and the mud reservoir portion 4 are connected, between the rising portion 3 and the mud reservoir portion 4. By being sandwiched, the bucket guide 6 as a whole is further fixed inside the main body 2.

  The hanging portion 61 is not limited to the flange shape as long as it can be easily sandwiched between the connecting portion of the rising portion 3 and the mud reservoir portion 4, but originally (when the bucket guide 6 is not attached). In order not to reduce the connection (contact) area between the rising portion 3 and the mud reservoir portion 4 as much as possible, the lower end surface of the rising portion 3 side wall and / or the upper end surface of the mud reservoir portion 4 side wall can contact or be sandwiched. It is advantageous to have a possible flange shape (see FIG. 3).

  Further, as in the case of the rainwater mass 1 of the present embodiment, the side wall of the rising portion 3 functions as an insertion port, and the upper portion of the side wall of the mud reservoir 4 functions as a receiving port 40 for receiving the rising portion 3 as the insertion port. The hook portion 61 may have a flange shape that can abut or sandwich the stepped portion of the receiving port 40 of the mud reservoir 4 where the end surface of the entrance of the rising portion 3 and the end surface of the entrance of the rising portion 3 abut. That's fine. Although not shown, on the contrary, when the side wall of the rising portion 3 functions as a receiving port and the upper portion of the side wall of the mud reservoir 4 functions as an insertion port inserted into the receiving port of the rising portion 3 as a receiving port, Any flange shape may be used as long as the end face of the inlet of the reservoir 4 and the end face of the inlet of the mud reservoir 4 are in contact with each other and can be brought into contact with or stepped on the stepped portion of the receptacle of the rising portion 3.

  As described above, in the rainwater trough 1 of the present embodiment, the bucket guide 6 is configured as an independent component separate from the rising portion 3 and the mud reservoir 4 and is sandwiched between the rising portion 3 and the mud reservoir 4. Therefore, it is not necessary to provide the bucket guide 6 in the rising part 3 and even a general-purpose circular pipe can be used as the rising part 3 of the rainwater 1 4 can be connected to the top.

  It is preferable that the guide part 60 of the bucket guide 6 is disposed so as to be able to contact the vicinity of the upper edge of the bucket 5 as much as possible so that foreign matter does not accumulate on the upper part of the guide part 60. On the other hand, the hook portion 61 of the bucket guide 6 is generally fixed to the connecting portion between the mud reservoir 4 and the rising portion 3 that is present at a position lower than the height of the bucket 5. In many cases, they are spaced apart in the height direction.

  For this reason, the connecting portion 62 of the bucket guide 6 serves to connect the guide portion 60 and the hooking portion 61 that are separated from each other. In this embodiment, in consideration of preventing rattling of the bucket guide 6 after mounting. The cylindrical shape is slidable on the inner peripheral surface of the rising portion 3. The guide portion 60 and the connecting portion 62 of the bucket guide 6 are integrally formed to form a U-shaped cross-sectional shape downward or a U-shaped cross-sectional shape downward in a sectional view. Since the section modulus of the portion 62 is also increased, the rigidity of the bucket guide 6 as a whole can be increased.

  The connecting part 62 is not limited to a cylindrical shape as long as the guide part 60 and the hanging part 61 which are separated from each other can be connected to each other. For example, the connecting part 62 and the hanging part 61 are arranged at a plurality of locations. A bar-like member arranged in a ladder shape that is partially connected may be used. Furthermore, when the guide part 60 and the hook part 61 are close to each other, the connecting part 62 may be omitted and the guide part 60 and the hook part 61 may be directly connected.

  As will be understood with reference to FIGS. 2 and 3, the mud reservoir 4 of the present embodiment is a bottomed cylindrical body, and has a plurality of water permeable holes 41 on the side wall of the mud reservoir 4. . Although not shown, the water permeable holes 41 may be replaced with a plurality of slits or a combination of the water permeable holes 41 and slits. In the rainwater trough 1 of the present embodiment, when the bucket 5 is mounted in the mud reservoir 4, the upper end of the water permeable hole 41 at the highest position among the water permeable holes 41 of the mud reservoir 4. Has a plurality of through holes 53 arranged at a higher position (see FIG. 3). Although not shown, the through hole 53 may be replaced with a plurality of through slits or a combination of the through holes 53 and the through slits.

  In the rainwater trough 1 of the present embodiment, a bottomed cylindrical mud reservoir portion 4 having a plurality of water permeable holes 41 provided on the side wall is provided at the bottom of the rainwater trough 1 so as to surround the bucket 5. A bucket 5 is detachably mounted in the mud reservoir 4. Rainwater containing foreign matter such as mud and dead leaves that has flowed in through the branch connection port 7 flows into the bucket 5, but since no through hole 53 is provided in the lower region of the bucket 5, rainwater that has flowed into the bucket 5, etc. Temporarily stays in the lower region in the bucket 5, and foreign substances contained in rainwater or the like accumulate in the lower region in the bucket 5. When rainwater or the like accumulates in the bucket 5, only the supernatant liquid such as rainwater that remains in the bucket 5 is discharged to the outside of the bucket 5 through the through hole 53 provided in the upper region of the bucket 5. The supernatant liquid such as rainwater discharged to the outside is then provided in the mud reservoir 4 and drained to the outside of the mud reservoir 4 through the water-permeable holes 41.

  For this reason, if a plurality of water permeable holes 41 are provided on the side wall of the mud reservoir 4 as described above, and a plurality of through holes 53 are provided in the bucket at a position higher than the water permeable holes 41 of the mud reservoir 4, rainwater will drain. 1 functions even if it penetrates, and foreign matter contained in rainwater etc. remains in the lower region in the bucket 5, so foreign matter will rain, so the crushed stone tank spread outside the rainwater 1 (not shown) And the crushing tank can be prevented from being clogged.

  Further, since the bucket 5 mounted in the mud reservoir 4 is detachable as described above, when removing the accumulated foreign matter, the bucket 5 is further extracted from the inspection port 20 of the main body 2 and the bucket 5 is removed. Since the extraneous work such as discarding the foreign matter in 5 can be done, the maintainability of rainwater 1 is improved.

  In the rainwater maser 1 of this embodiment, either the water permeable hole 41 of the mud reservoir 4 or the through hole 53 of the bucket 5 may be omitted, or both the water permeable hole 41 and the through hole 53 may be omitted. May be. If the permeation hole 41 of the mud reservoir 4 is omitted, the rainwater masu 1 will not function as a permeate, but it can be used as a normal rainwater masu 1.

  The perspective view which shows the spigot 70 of the branch pipe connection port 7 of this embodiment attached to the inner wall of the standing part 3 of the main body 2 is shown by FIG. FIG. 6 shows a cross-sectional view (a) of the spigot 70 shown in FIG. 5 taken along the line BB and a cross-sectional view (b) taken along the line CC. FIG. 7 is a perspective view showing the socket 71 of the branch pipe connection port 7 of this embodiment attached to the outer wall of the rising portion 3 of the main body 2. FIG. 8 shows a cross-sectional view (a) of the socket 71 shown in FIG. 7 cut along a DD cross-section and a cross-sectional view (b) cut off along a EE cross-section.

  As shown in FIGS. 1 to 3, the rainwater mast 1 of this embodiment is connected to the rainwater mast from the outside as an inlet for flowing rainwater into the rainwater mast from the outside. The outlet 7 (left side of FIGS. 1 to 3) and the branch connection port 7 of this embodiment that communicates from the rainwater to the outside as an outlet for draining rainwater from the rainwater 1 to the outside (see FIGS. 1 to 3) The right side) is attached at the same height of the rising portion 3 while changing the direction by 180 ° in the horizontal direction. Since the branch pipe connection port 7 of this embodiment is retrofitted to the opening 30 provided on the side wall of the rising portion 3, it can be attached to a free position (height, direction) of the rising portion 3 in an arbitrary direction. it can. In addition, the opening part 30 of the rising part 3 can be provided in the arbitrary positions of the side wall of the rising part 3 by punching the side wall of the rising part 3 using a hole saw etc. in a construction site.

  As shown in FIGS. 2 and 3, the branch pipe connection port 7 of the present embodiment has a spout 72 and is fitted to the spigot 70 attached to the inner surface of the side wall of the rising portion 3, and the spigot 70. The socket 71 has a mating opening 74 and is attached to the outer surface of the side wall of the rising portion 3.

  In the present embodiment, one branch pipe connection port 7 part having an insertion port is called a spigot, and another branch pipe connection port 7 part having a receiving port is called a socket. For this reason, although not shown, the spigot 70 and the socket 71 can be exchanged with respect to the inner surface and the outer surface of the side wall of the rising portion 3, and specifically, the spigot 70 having the opening 72 is replaced with the rising portion. A socket 71 having a receiving port 74 attached to the outer surface of the three side walls can be attached to the inner surface of the rising portion 3 side wall.

  As is well understood with reference to FIGS. 5 and 6, the spigot 70 includes an insertion opening 72 that passes through the opening 30 of the rising portion 3, and is fixed to the outer peripheral portion of the insertion opening 72 and inside the rising portion 3. And a spigot flange 73 curved along the side wall. Further, the spigot 70 has a stepped portion 76 whose outer diameter is larger in the region near the root of the spigot flange 73 than the outer diameter of the region other than the vicinity of the spigot flange 73 at the outer periphery of the spigot 70. Is included.

  The spigot 70 and the socket 71 of the branch pipe connection port 7 of this embodiment are made of vinyl chloride resin. Therefore, when an adhesive made of an organic solvent is applied to the stepped portion 76 (region near the root of the spigot flange 73) of the spigot 70 whose diameter has been expanded, it softens. The insertion opening 72 of the spigot 70 can be easily inserted into and closely adhered to the opening 30 of the rising portion 3 without generating a gap with the three opening portions 30.

  For this reason, the branch pipe connection port 7 of the present embodiment prevents core misalignment (rattle) that occurs between the opening 30 of the rising portion 3 while maintaining high insertability of the insertion port 72 of the spigot 70, and It is possible to prevent water leakage and improve water stoppage from the opening 30 of the rising portion 3 (attachment portion of the branch pipe connection port 7). Further, in the present embodiment, in order to eliminate an excessive insertion length of the stepped portion 76 and to allow a higher insertion property of the insertion opening 72 of the spigot 70, the stepped diameter of the insertion opening 72 of the spigot 70 is increased. The width dimension of the attachment portion 76 (region near the root of the spigot flange 73) is made substantially the same as the thickness of the rising portion 3 (see FIG. 3). In this case, since the curved socket flange 75 abuts both the stepped portion 76 of the spigot 70 and the side wall of the rising portion 3, there is also an effect of making it difficult to generate a gap in the attachment portion of the branch pipe connection port 7.

  The spigot flange 73 includes a rod-shaped first bone member 730 that forms an outline of the spigot flange 73 and a stepped portion 76 of the spigot 72 of the spigot 70 in order to join the spigot flange 73 to the spigot 70 of the spigot 70. The rod-shaped second bone member 731 formed so as to surround the spigot flange 73 and the first bone member 730 and the second bone member in order to reinforce the spigot flange 73 and increase the bonding area with the rising portion 3. A planar member 732 joined to 731 is included. In addition, in order to facilitate the removal and insertion of the bucket 5 from the inspection port 20, the inside of the left and right vertical bone members of the first bone member 730 is slidably contacted with the vertical member of the handle 50 of the bucket 5. A handle guide groove 733 is formed.

  The spigot flange 73 is curved in a convex shape so as to follow the inner side wall shape of the rising portion 3 as a whole. However, the spigot flange 73 does not necessarily have to be a complete planar body, and can be brought into contact with the rod-like members 730 and 731 as in the present embodiment as long as the spigot flange 73 can be closely adhered along the side wall shape of the rising portion 3. A combination of the cylindrical members 732 or a combination of a plurality of rod-shaped members in a lattice shape or the like may be used. In the spigot 70 of this embodiment, the weight reduction of the whole spigot flange 73 and the required strength guarantee are made compatible by combining the rod-like members 730 and 731 and the planar member 732.

  Moreover, in this embodiment, when attaching the spigot 70 to the outer surface of the rising part 3 side wall, the spigot flange 73 should just be curved concavely so that the outer side wall shape of the rising part 3 may be followed as a whole.

  As is well understood with reference to FIGS. 7 and 8, the socket 71 has a receiving port 74 that fits into the insertion port 72 of the spigot 70, and is fixed to the outer periphery of the receiving port 74 and is outside the rising portion 3. And a socket flange 75 curved so as to extend along the line. For this reason, the inner diameter of the socket 74 of the socket 71 is substantially the same as the outer diameter of the outlet 72 of the spigot 70. Moreover, the stopper for preventing the excessive insertion of the spigot 70's insertion port 72 by making the tip of the spigot 70's tip 72 contact | abut inside the receptacle 74 of the socket 71 by contact | abutting. 710 is formed in a ring shape so as to protrude inward from the inner surface of the receiving port 74.

  The socket flange 75 is formed from a plate-like member that is concavely curved so as to follow the shape of the outer side wall of the rising portion 3, but is not necessarily plate-like or completely planar, and the side wall shape of the rising portion 3 As long as it can be closely attached to each other, a combination of a bar-like member and a planar member, such as a spigot flange 73, or a combination of a plurality of bar-like members in a lattice shape may be used.

  Moreover, in this embodiment, when attaching the socket 71 to the inner surface of the rising portion 3 side wall, the socket flange 75 may be curved in a convex shape so as to follow the inner side wall shape of the rising portion 3 as a whole.
