Materials for the rainwater tank 1 include polyvinyl chloride and polypropylene. For example, in terms of cost, it is possible to manufacture polypropylene at a low cost, but as will be described later, the riser pipe 19 cannot be adhered, so the structure is to be connected by a joint. On the other hand, when it is possible to bond such a riser pipe 19, polyvinyl chloride is adopted.

Here, in the rainwater basin 1 of this embodiment, the central axes of the basin main body 10, the riser pipe socket 11, and the mud pool 12 are arranged on a common axis. Hereinafter, this common axis will be referred to as the mass axis O, the side of the rainwater basin 1 facing the mud pool 12 along the direction of the mass axis O will be referred to as the lower side, and the riser pipe socket 11 side of the rainwater basin 1 will be referred to as the upper side. Further, in a plan view of the rainwater basin 1 viewed from the direction of the basin axis O, the direction orthogonal to the basin axis O is called the radial direction, and the direction rotating around the basin axis O is called the circumferential direction.

The mass main body 10 is provided with connecting portions 10b, 10b that connect the outer peripheral wall 10a to the riser pipe socket 11 and the mud pool 12, respectively. The outer peripheral wall 10a for horizontal pulling pipes 4 is formed in a cylindrical shape centered on the mass axis O, has an outer diameter of 330 mm or less, and has a height larger than the diameter dimension of the insertion ends 4a (4b) of the horizontal pulling pipes 4. is set.

Further, as shown in FIGS. 7 and 8, a reference line 15 indicating the formation position of the insertion opening 13 is displayed on the lateral insertion outer peripheral wall 10a. The first reference line 15A shown in FIG. 7 is displayed from lines extending in the circumferential direction on the outer surface of the laterally inserted outer peripheral wall 10a and a plurality of lines extending in the vertical direction (vertical direction) orthogonal to the circumferential direction. . The second reference line 15B shown in FIG. 8 is indicated by a line consisting of triple concentric circles at predetermined angles (for example, 45°) along the circumferential direction.

The riser pipe socket 11 has a base end portion 11A connected to the mass body portion 10 from above, and a socket main body 11B having a slightly larger diameter than the base end portion 11A. A socket main body 11B is coaxially arranged. A riser pipe 19 is connected to the socket main body 11B by adhesion (when the rainwater tank 1 is made of polyvinyl chloride). A riser pipe 19 connected to the rainwater basin 1 extends to the ground at its upper end and is fitted with a protective hat (not shown) on its upper end.

The mud pool portion 12 is formed to have a smaller diameter than the mass body portion 10, and the outer diameter of the mud pool portion 12 is set to 180 mm or less.

In the rainwater tank 1 constructed in this way, as shown in FIG. The insertion angle θ1 between the first horizontal pipes 4A, 4A of 114 mm) is 90°, and the second horizontal pipe 4B with a nominal diameter of φ75 (outer diameter 89 mm) is placed between the first horizontal pipes 4A, 4A. is provided at an insertion angle θ2 of 45° with respect to the first horizontal pulling pipe 4A. In FIG. 5, reference numerals C1 and C2 (C) denote the central axes of the first horizontal pulling pipe 4A, and the angle θ1 between these central axes C1 and C2 is 90°. In FIG. 5, reference symbol C3(C) is the central axis of the second horizontal pipe 4B, and the angle .theta.2 between the central shafts C1 and C2 of the first horizontal pipes 4A and 4A is 45.degree. The insertion end portion 4a of the first horizontal pulling pipe 4A is located at the outer peripheral edge of the opening of the mud pool portion 12 when viewed from above. Also, the insertion end 4b of the second horizontal pull-out tube 4B is positioned to abut on the pair of first horizontal pull-up tubes 4A, 4A, and an insertion length of 40 mm is ensured at this time.
The total length of the rainwater basin 1 is preferably 350 mm or less, and the total length of the mud pool portion 12 is preferably 150 mm or more.

Next, the construction method for connecting the horizontal pipe 4 to the rainwater basin 1, the rainwater basin, and the operation of the rainwater basin construction method will be described in detail with reference to the drawings.
In the present embodiment, as shown in FIG. 1, when connecting the rainwater catch 1 to the horizontal pipe 4, first, at an arbitrary position on the outer peripheral wall 10a of the main body 10 of the main body 10, As shown, an insertion opening 13 (see FIGS. 5 and 6) having a predetermined outer diameter is formed by penetrating the outer peripheral wall 10a by laterally pulling using a punching jig 5 (piercing means). Here, as the drilling jig 5, an electric jig having a cutter 52 at the tip of the rotating shaft 51 can be adopted.

As shown in FIG. 6 , the lateral pipe 4 is inserted into the insertion port 13 through the waterproof packing 14 to the inside of the mass body 10 . Specifically, the water stop packing 14 is provided between the outer peripheral surface 42 a of the thin end portion 42 of the horizontal pipe 4 and the insertion port 13 . At this time, the horizontal pulling pipe 4 is inserted into the insertion port 13 so that the insertion end portion 4a (4b) of the horizontal pulling pipe 4 is positioned radially outside the upper end opening edge of the mud pool portion 12 (see FIG. 5). ). It is possible to provide a structure in which the insertion end portion 4a (4b) of the lateral pull pipe 4 inserted in this manner does not overlap the opening of the mud pool portion 12 in the mass axis O direction. As a result, a basket or the like for cleaning the inside of the mud pool 12 can be inserted into the mud pool 12 without interfering with the inserted lateral pipe 4 .

In the rainwater tank 1 constructed in this manner, the outer diameter of the mud pool 12 is smaller than the outer diameter of the main body 10 into which the insertion end 4a of the horizontal pipe 4 is inserted. 1 can be made compact. That is, in the rainwater basin 1 of the present embodiment, as shown in FIG. 10(a), a space S is formed below the basin main body 10 in the rainwater basin 1 and radially outside the mud pool 12. When the drainage pipe P1 for rainwater and the drainage pipe P2 for sewage generated from the room are arranged in different systems underground in a house or the like, the drainage pipe P2 for sewage can be arranged in the space S. It becomes possible.
Therefore, the distance L1 between the rainwater drain pipe P1 and the sewage drain pipe P2 is set to the rainwater drain pipe P1 in the conventional case using the bucket-shaped trout 1A as shown in FIG. 10B, for example. Compared to the distance L2 of the drainage pipe P2 for sewage, it can be made closer, and the piping can be efficiently installed in a house in a narrow place.

Further, in the present embodiment, as shown in FIG. 6, a predetermined hole opening means (a hole punching jig 5 shown in FIG. 9) is used at an arbitrary position on the outer peripheral wall 10a of the mass main body 10 for horizontal pulling. An insertion port 13 having an outer diameter can be formed, and a horizontal pipe 4 can be inserted into the insertion port 13 through a waterproof packing 14 and connected to the inside of the mass body 10 . In this way, the angle of inflow and outflow of the lateral pipe 4 can be freely set at the construction site.
Therefore, the angle of inflow and outflow of the horizontal pipe 4 can be adjusted and the rainwater Problems such as carrying in a mass with a wrong shape for the socket of the mass can be eliminated, the degree of freedom of piping can be increased, and workability at the site can be improved.

When forming an insertion opening 13 with a predetermined outer diameter at an arbitrary position on the outer peripheral wall 10a of the mass main body 10 using a hole making means (piercing jig 5 shown in FIG. 9), the laterally extending outer wall By providing alignment holes 10g (see FIGS. 12 and 13) corresponding to each hole diameter (for example, 50A, 75A, and 100A) in 10a, when drilling holes with the drilling jig 5 at the construction site, desired holes can be formed. The diameter can be formed where desired.
For example, by marking the hole diameter on the alignment hole 10g, it is possible to recognize at a glance which alignment hole 10g has the desired hole diameter, thereby improving working efficiency.
Further, the alignment holes 10g are preferably formed on the same straight line as the center position of the hole formed by the hole punching jig 5, but may be formed by being displaced.

Moreover, in this embodiment, the outer diameter of the mass body 10 is larger than the outer diameter of the mud pool 12, and the lateral pull pipe 4 is laterally pulled through the outer peripheral portion of the mass body 10 and inserted into the outer peripheral wall 10a. The insertion length of the insertion end portion 4a (4b) of the horizontal pulling pipe 4 to be inserted can be ensured. Therefore, the connection by inserting the horizontal pipe 4 can be reliably performed, and the inserted end 4a (4b) of the horizontal pipe 4 can be prevented from overlapping the opening of the mud pool 12 in the direction of the mass axis O. It is possible to have a structure without As a result, a basket or the like for cleaning the inside of the mud pool 12 can be inserted into the mud pool 12 without interfering with the inserted lateral pipe 4 .

Further, in this embodiment, the mud pool portion 12 can be made of a member with a small cross section having an outer diameter of 180 mm or less, so that the size of the rainwater tank 1 can be reliably reduced.
Further, the laterally-pulled outer peripheral wall 10a is formed in a cylindrical shape and has an outer diameter of 330 mm or less. 114 mm) can be horizontally pulled and inserted into the outer peripheral wall 10a.

Furthermore, in the present embodiment, as shown in FIGS. 7 and 8, an insertion opening 13 (see FIG. 5) can be formed, which eliminates the need for a positioning operation for making a hole, and allows the insertion opening 13 to be formed with high precision.

As described above, in this embodiment, it is possible to reduce the size, and the angle of inflow and outflow of the horizontal pipe 4 can be freely set at the construction site, so that the degree of freedom of piping can be increased. It is possible to improve the workability in

(Second embodiment)
A rainwater basin 1A of the second embodiment shown in FIGS. 11A and 11B is a base end portion 11A of the riser pipe socket 11 in the rainwater basin 1 shown in FIG. 2 according to the first embodiment. and the base end portion 12A of the mud pool portion 12 are omitted, and two members (upper member 10A, lower member 10B ). That is, the rainwater tank 1A has a structure in which two members are formed by injection molding and joined to each other with an adhesive.
It should be noted that the two members can be kept joined together by fitting the respective members instead of the adhesive.

As shown in FIG. 11(a), an upper member 10A is formed by integrally injection-molding a laterally extending peripheral wall 10a of a mass body portion 10, an upper connecting portion 10b, and a socket main body 11B of a riser pipe socket 11. It is a member that has been The lower member 10B is a member in which the continuous portion 10b on the lower side of the mass body portion 10 and the mud pool body 12B of the mud pool portion 12 are integrally injection molded. In the present embodiment, the continuous portions 10b of the upper member 10A and the lower member 10B form planes perpendicular to the direction of the mass axis O, but the continuous portions 10b may be inclined. Mud and water can easily flow into the mud pool 12 by providing an inclination in the continuous portion 10b.

The connecting portion 10b of the lower member 10B is formed with a protruding edge portion 10e extending over the entire outer peripheral edge thereof and for adhering the lower end portion 10d of the upper member 10A. The lower end portion 10d of the upper member 10A is arranged in a fitted state on the inner peripheral side of the projecting edge portion 10e and adhered with an adhesive. The rainwater receptacle 1A shown in FIG. 11(b) is penetrated by punching a predetermined portion of the laterally inserted outer peripheral wall 10a using a hole punching jig 5 (see FIG. 9), and an insertion port 13 having a predetermined outer diameter is formed. formed.

A stopper 10f is formed on the receptacle main body 11B to extend in a direction intersecting with the continuous portion 10b. By forming the stopper 10f, when inserting the horizontal pull pipe 4, the amount of insertion can be controlled, and the insertion end 4a of the horizontal pull pipe 4 is prevented from entering the position of the outer peripheral edge of the opening of the mud pool portion 12. can. As a result, when taking out the mud accumulated in the mud pool 12, a bucket (described later) housed inside the mud pool 12 can be easily taken out.

In the second embodiment, as described above, the base end portions 11A and 12A (see FIG. 2) of the riser pipe socket 11 and the mud pool portion 12 are omitted, respectively, so that the overall shape of the rainwater basin 1A is reduced. can be made smaller. In addition, since the upper member 10A and the lower member 10B are integrally bonded together, each member can be manufactured not only by injection molding but also by using a mold.

(Third Embodiment)
As shown in FIGS. 12 to 14, a rainwater receptacle 1B according to the third embodiment is a more specific version of the rainwater receptacle 1A (see FIGS. 11A and 11B) according to the second embodiment described above. It is configured as follows.
The rainwater receptacle 1B is composed of two vertically divided two members (an upper member 6A and a lower member 6B), and can be formed by injection molding or the like. Here, the upper member 6A has a cylindrical laterally-pulled outer peripheral wall 60 capable of forming an insertion opening 60a (see FIG. 13) into which the insertion ends 4a, 4b of the laterally-pulled pipe 4 shown in FIG. 5 are inserted. It corresponds to the mass body. The upper member 6A includes a riser pipe receiving port 61 for connecting the riser pipe 19 (see FIG. 14) at the upper end, an upper connecting portion 62 for connecting the laterally inserted outer peripheral wall 60, a laterally inserted outer peripheral wall 60 and a lower and a lower connecting portion 63 connecting the members 6B.

The riser pipe receptacle 61 is formed of a cylindrical body having a diameter smaller than that of the laterally inserted outer peripheral wall 60 . The upper connecting portion 62 is a ring-shaped flange that connects the vertical intermediate portion of the riser pipe socket 61 and the upper end of the laterally inserted outer peripheral wall 60 and extends along the circumferential direction. A plurality of vertically protruding reinforcing ribs 64 are arranged in the upper continuous portion 62 at intervals in the circumferential direction. Of the reinforcing ribs 64 , an upper reinforcing portion 64 A located above the upper connecting portion 62 is connected to the upper surface 62 a of the upper connecting portion 62 and the outer peripheral surface 61 a of the riser pipe socket 61 . On the other hand, the lower reinforcing portion 64B located on the lower side of the upper continuous portion 62 includes the lower surface 62b of the upper continuous portion 62, the outer peripheral surface 61a of the riser pipe socket 61, and the inner peripheral surface 60c of the laterally extending outer peripheral wall 60. It is connected to the.

When combining the two molded members, the upper member 6A and the lower member 6B, a load is applied to the lower member 6B from the direction of the axis O of the rainwater basin 1B, and the upper member 6A is inserted to form the rainwater basin 1B. It is formed. At this time, since the upper connecting portion 62 is provided with the reinforcing ribs 64, the deformation of the upper connecting portion 62 due to the load applied to the laterally extending outer peripheral wall 60 of the upper member 6A and the upper connecting portion 62 is prevented. can be prevented, and the strength of the rainwater catch 1B against stress can be improved.
Note that the reinforcing ribs 64 need only be formed at locations that do not interfere with the design. Instead, the lower reinforcing portion 64B can be formed at a position inside the rainwater basin 1B.

In the upper member 6A, the position of the insertion lower end 61b of the riser pipe 19 in the riser pipe socket 61 is located below the position of the outer peripheral upper edge portion 60b of the laterally extending outer peripheral wall 60 of the upper member 6A. As a result, the riser pipe 19 can be deeply inserted into the rainwater basin 1B, and the rainwater basin 1B can be made compact.
The position of the lower insertion end 61a into which the riser pipe 19 is inserted is below the outer peripheral upper edge portion 60b as described above, and the laterally drawn pipe inserted into the insertion port 60a of the laterally inserted outer peripheral wall 60 4 (see FIG. 5) is sufficient, and the height can be determined by appropriately adjusting the height during construction.

The lower member 6B is detachably connected to the lower connecting portion 63 of the upper member 10A, and corresponds to the tubular mud pool portion described above. The lower member 6B is formed with a smaller diameter than the upper member 6A. The lower member 6B has a bottomed cylindrical mud pool receiving portion 65 and a mounting portion 66 projecting radially outward from the upper portion of the mud pool receiving portion 65 (see FIG. 15). The mounting portion 66 is connected to the lower continuous portion 63 of the upper member 6A in a fitted state, and is provided with a plurality of reinforcing ribs 67 spaced apart in the circumferential direction.

In this case, as shown in FIG. 16, when the upper member 6A and the lower member 6B are combined, the lower end 67b of the reinforcing rib 67 of the lower member 6B is aligned with the upper end portion of the riser pipe socket 61 of the upper member 6A. A plurality of rainwater receptacles 1B can be stacked vertically and stored by engaging them with respect to 61c so as to be placed from above. Here, FIG. 16 shows a state in which a set of rainwater receptacles 1B are superimposed and stacked. With such a configuration, the storage space can be reduced, and the storage efficiency can be improved.

17, the lower end 67b of the reinforcing rib 67 is formed with a notch 67a with which the upper end 61c of the riser pipe socket 61 of the upper member 6A is engaged. That is, by engaging the upper end portion 61c of the riser pipe socket 61 of the upper member 6A with the notch portion 67a of the lower member 6B, a plurality of rainwater receptacles 1B are vertically arranged while the upper member 6A and the lower member 6B are combined. can be stacked and stored.
As another configuration, it is possible to omit the above-mentioned notch 67a by enlarging the hole in the peripheral portion of the lower member 6B.

Further, in this embodiment, as shown in FIG. 18, a bucket 16 for accumulating mud is provided on the inner side of the trough main body 60 so as to be able to be inserted into and pulled out from the riser pipe socket 61 of the upper member 6A, and the rainwater trough 1B is used. It is also possible to contain the mud that accumulates inside. The bucket 16 has a size that can be accommodated in the mud pool receiving portion 65 of the lower member 6B, and is set to a size that does not interfere with the horizontal pull pipe 4 inserted into the upper member 6A when passing through the upper member 6A. . The bucket 16 is detachably provided with a handle 161 used for taking out. When taking out the mud accumulated inside the bucket 16, the mud can be efficiently removed by taking out only the bucket 16 by holding the handle 161. - 特許庁After the mud in the bucket 16 is removed, the bucket 16 can be accommodated in the mud pool 12 again.

For the bucket 16, for example, polyolefin such as polyethylene or polypropylene can be used. In this case, since the mud pool 65 is made of vinyl chloride, the hardness of the mud pool 65 is lower than that of the mud pool 65 . buoyancy can prevent the bucket 16 from floating.

Further, the bucket 16 may be provided with a socket (not shown) for detachably locking a rod-shaped member such as a narrow tube on the upper surface of the bottom. In this case, when the bucket 16 is taken out from the mud pool 65, the bucket 16 can be taken out from the rainwater basin 1B by connecting the thin tube to the socket and then pulling up the thin tube, thereby simplifying the cleaning work. It can be done easily. The length of the thin tube can be appropriately adjusted during construction, and the bucket 16 is held down by the thin tube by placing a lid on the thin tube, thereby preventing the bucket 16 from rising due to water.
