Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin assembly.
[0002]
[Prior art]
Generally, a building is unitized by a structure in which members are produced in advance and assembled at a construction site, that is, a prefabricated structure (industrialized structure).
[0003]
According to this, it is said that the stability of the quality can be obtained by reducing the amount of labor at the site, shortening the entire construction period, and producing in a factory under well-equipped conditions.
[0004]
For this reason, pipes are unitized for indoor water supply and hot water supply, but rationalization by unitization is also strongly demanded for indoor drain pipes.
[0005]
Therefore, various proposals have been made on the unitization of indoor drain pipes (also referred to as prefabricated pipes) (for example, JP-A-4-368523, JP-A-5-156675, JP-A-7-71676, JP, 2001-40745, JP, 2001-220792, etc.).
[0006]
For example, the above-mentioned Japanese Patent Application Laid-Open No. 2001-40745 discloses that the drainage of a sink, a sink, a bathtub, a washing machine (these are also referred to as miscellaneous drainage devices) and the like are discharged to the outside. In the pocket space with the slab surface, the main body is provided with an inspection port for inspecting the interior, an outlet for discharging wastewater, and an inlet for draining water from the sink, etc. An assembly in which a lid for sealing the mouth is provided, connected to the outlet, provided with one discharge main pipe for discharging waste water to the outdoors, and the sink and the inlet are connected by a drain branch pipe made of a flexible pipe In-house underfloor piping is introduced.
[0007]
And when the drainage branch pipe in such underfloor piping is cut and processed in advance at the production factory etc. and connected to the inflow port, it is carried into the construction site and installed, so positioning of the underfloor piping is omitted, and the construction period is greatly shortened In addition, it is said that labor costs can be saved, water-tightness testing at the construction site can be omitted, and the product can be made extremely reliable.
[0008]
However, in such a collection of underfloor pipes, even if an inverter is formed at the bottom of the pipe, if the flow rate of the inflowing wastewater is high, the wastewater flowing in from one inflow port will flow backward to the other inflow port, If solid matter is contained in the drainage, there is a risk of accumulation at the other inflow port.Therefore, even if a partition plate is provided to allow the inflowing wastewater to flow smoothly, Since the passage is narrow, if the flow rate of drainage is slow, there is a problem that the solid matter tends to stay.
[0009]
On the other hand, a general household wastewater which attempts to solve such a problem has been proposed as follows (see Japanese Patent Application Laid-Open No. 11-280137).
[0010]
In other words, depending on the situation of drainage flowing in from the inlet, a partition plate that prevents backflow to other inlets and prevents clogging of the drainage drainage is detachably provided. It has been proposed that the drainage in the house is designed to change the flow direction.
[0011]
[Problems to be solved by the invention]
However, in the drainage with a removable partition plate, one of the drain branch pipes is connected to the toilet and the other is connected to the drain pipe on the floor, so that the solid matter is filth. Or because it is used in the situation of drainage where the flow velocity of the flow is extremely high, there is a problem that it cannot be applied to the gathering in the underfloor piping having different conditions.
[0012]
In addition, since such a household drainage basin uses a long inspection cylinder, there is a problem that it cannot be applied to the pocket space (height of about 400 to 600 mm) between the floor and the slab surface.
[0013]
Therefore, the main object of the present invention is to eliminate such problems, and the secondary object is to make the height of the aggregate in the underfloor piping as low as possible.
[0014]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides: 1) an underfloor pipe that has one outflow port and a plurality of inflow ports in the main body, and is closed by a lid at the upper upward fitting port of the main body. In the assembly made of synthetic resin, the opening side in the main body of the plurality of inlets is partitioned by a vertical radial partition plate and an inverted L-shaped top plate adjacent to the partition plate. And the partition is provided on the lid so that the opening is covered in a bowl shape with the top plate to guide the drainage well and the height of the assembly is reduced. 2) The main body has one outlet and multiple inlets, and there is a step between these inlets and outlets. The upper part of the main body is formed with a lid at the upward fitting port. In the assembly of stepped synthetic resin such as underfloor piping, the opening side in the main body of the plurality of inlets is a radial partition plate in the vertical direction, and an inverted L-shaped top plate adjacent to the partition plate. The partition is provided with the lid, and the partition is provided while the step is secured, and the opening is covered in a bowl shape by the top plate to guide the drainage well. 2. The assembly according to claim 1, wherein the assembly is made of synthetic resin, such as underfloor piping, characterized by lowering the height of the assembly, and 3) applied to the assembly drop. 4) The synthetic resin assembly according to claim 2 applied to a collective drainage assembly for underfloor piping, and 5) the partition. A plate and a top plate are suspended in the vertical direction of the lid. Plastic collection masu according to claims 1 to 4 provided on the one in which the subject matter.

The invention will be described in more detail by means of an embodiment shown in the drawing.
[0016]
1 is an overall view of an embodiment of the present invention, FIG. 2 is an external view of the main part of FIG. 1, FIG. 3 is a longitudinal sectional view of FIG. 2, FIG. FIG. 5 (A) is a plan view, FIG. 5 (B) is a side view of FIG. 5 (A), FIG. 6 is a bottom view (A) of FIG. FIG. 7A is a cross-sectional view (B) taken along arrow a in FIG.
[0017]
The unitized underfloor pipe for indoor drainage according to the embodiment of the present invention, that is, the collective collective drainage facility 1 is suitable for a wooden detached house, but can also be applied to a small-scale apartment house.
[0018]
In addition, the wooden structure in this specification includes a conventional shaft-framed wooden construction method, a two-by-four construction method, a large-section wooden construction using laminated wood, and the like.
[0019]
Of course, the present embodiment can also be applied to a detached house by a steel frame unit method.
[0020]
First, an outline of the collective collective drainage facility 1 will be described. In FIG. 1, for example, in order to construct a wooden house 2, the site is rooted and the foundation work such as a base footing and a cloth foundation 4 ′ is provided, such as a drain main pipe sleeve. Do it after doing.
[0021]
After curing the concrete for the foundation work, a moisture-proof concrete 3 is placed over the entire floor. At the time of placing the moisture-proof concrete, an anchor bolt 19 which will be described later is buried in the concrete.
[0022]
After the moisture-proof concrete 3 is cured, the assembly 4 is fixed and placed detachably by anchoring or the like, and one drain main pipe 5 is laid and connected to the assembly 4. After that, main body construction is performed, and then secondary indoor piping is performed along with the internal construction.
[0023]
That is, for example, when the interior work of the kitchen is performed, the sink and the set 4 are connected to the drainage branch pipe 6 using a flexible pipe in a one-touch manner by the miscellaneous equipment connecting socket 7.
[0024]
The length of the drainage branch pipe 6 is cut to a length previously determined from the construction drawing. Therefore, a predetermined flow gradient can be obtained only by connecting.
[0025]
Similarly, the drainage branch pipe 6 is connected to the existing collective mass 4 for each internal work for installing the wash basin, the washing machine, and the bathtub.
[0026]
This set 4 is placed in the pocket space under the floor 8 of the wooden house 2, and an inspection port (not shown) is provided on the floor 8 directly above it so that it can be opened and closed. I am doing so. In FIG. 1, 9 indicates joists.
[0027]
Since it is a construction method of collective drainage 1 for indoor drainage such as for detached houses as described above, construction accuracy is improved, and multi-purpose workers such as concrete construction contractors can sufficiently pipe, While preventing the construction time lag, labor costs associated with construction (which accounts for about 70% of piping construction costs) can be reduced, and the number of outdoor household wastewater can be reduced.
[0028]
Next, the collective mass 4 in the collective collective drainage equipment 1 for indoor drainage as described above will be described in detail.
[0029]
First, the outline of this set 4 will be described. 2 and 3, this assembly 4 is constituted by a so-called synthetic resin (vinyl chloride injection molding) confluence step formed in a circular shape (of course, can be a quadrilateral shape) in a plan view. A number of drainage branch pipes 6 can be connected in parallel and perpendicular to the pipe axis.
[0030]
That is, the main body 10 has a relatively large diameter (for example, 100 mmφ) drain main pipe connection port (specifically, a rubber ring receiving port but also expressed as an outflow port) 11 and a plurality of the main body 10 in a horizontal direction. (4) relatively small-diameter (for example, 60 mmφ) drainage branch connection ports (specifically, one-touch connection ports, but also expressed as inflow ports) 12, 12. An invert portion 13 having a step (for example, 55 mm) S is formed between the drain main pipe connection port 11 and the drain branch port connection port 12.
[0031]
In addition, a lid fitting port 14 having a large diameter (for example, 200 mmφ) is formed upward on the main body 10 in the form of a cylindrical body, and a lid 15 with a partition 17 is detachably attached to the lid fitting port 14. In addition, the sewage odor is prevented from leaking indoors by completely sealing through the lip packing 16.
[0032]
And even if the drainage from various indoor drainage devices flows in by providing a plurality of drainage branch connection ports 12 as described above, the details of the partition 17 and a relatively large step S will be described later. Therefore, it does not flow back to the other drainage branch pipe 6.
[0033]
Further, as shown in FIGS. 2 and 4, an anchor bolt flange 18 is formed at the lower portion of the main body 10, and a plurality of anchor bolts driven into the moisture-proof concrete 3 are formed on the flange 18. 19 and 19 are engaged, and the main body 10 is placed and fixed on the moisture-proof concrete 3 to facilitate underfloor piping work.
[0034]
The drainage main pipe 5 is supported by a support fitting 20 fixed by a moisture-proof concrete 3 and piped on the moisture-proof concrete 3, and the moisture-proof concrete 3 and the fabric foundation 4 ′ are connected via an elbow 21. It penetrates and connects to an outdoor trap (not shown).
[0035]
Here, in this main body 10, two parallel drainage branch connection ports 12 are formed in advance on three sides other than the drainage main pipe connection port 11 side. A single inflow connection port (12) can be formed, which is convenient for piping that lowers the height of the assembly 4 and that there are not enough deficiencies in various types of miscellaneous drainage devices, and it is easy to connect from the same direction. can do. Moreover, since the two parallel inflows, it is possible to prevent rebound due to mutual flowing water in the main body 10. The unnecessary connection port (12) is closed.
[0036]
In particular, if the main body 10 is made of injection molding, it is easy to squeeze the mold for molding, and the productivity is improved without complicating the injection mold and molding machine. To do.
[0037]
Next, the partition body 17 will be described. 3, 5, and 6, the partition body 17 includes eight radial partition plates 22 each having a plurality of drain branch pipe connection ports 12, 12. A relatively large step S provided in the main body 10 is used to quickly and smoothly flow out to the drain main pipe connection port 11 and to prevent the drainage from splashing up. And a character-shaped top plate 23.
[0038]
Of course, the radial partition plate 22 is not limited to partitioning the drainage branch pipe connection port 12, but may also partition the two connection ports 12 and 12 together. Therefore, in this case, four partition plates 22 are sufficient.
[0039]
For this reason, the radial partition plate 22 prevents backflow to the other inlet (12) when drainage does not flow in, prevents drainage from flowing simultaneously and prevents splashing and scattering due to collision, and in particular, an upward wrapper. The inverted L-shaped top plate 23 formed by a part of the body 25 can be quickly drained by using the relatively large step S, and as a result, the height of the main body 10 can be suppressed as much as possible. Can be convenient for underfloor piping in limited pocket space.
[0040]
As a result, no pits or the like are formed in the moisture-proof concrete 3 or the like, and the placing work can be simplified.
[0041]
The radial partition plate 22 and the inverted L-shaped top plate 23 are integrally injection-molded with a central axis (a vertical axis) 24.
[0042]
That is, the minimum diameter portion of the upward trumpet body 25 is integrated with the lower portion of the pipe-shaped central shaft 24 as shown in FIG. 6B. As shown in (B), the four-way partition plates 22 and 22 are integrally formed so as to be partitioned at equal intervals in the vertical direction and radially about the central axis 24.
[0043]
As shown particularly in FIG. 5A, the upward trumpet body 25 has a disk shape in plan view, and the partition plate 22 projects from its maximum diameter (not projected in FIG. 3).
[0044]
As shown in FIG. 3, the inverted L-shaped top plate 23 formed of a part of the upward trumpet body 25 covers the inner opening of the main body 10 of the drainage branch pipe connection port 12 in a bowl shape so that drainage is good. To guide.
[0045]
Further, the radial partition plate 22 in which the lower end of the central shaft 24 and the lower end thereof substantially coincide with each other is substantially coincident with the height of the step S as shown in FIG. Even the partition plate 22 prevents the stagnation of drainage and immediately flows down to the step S.
[0046]
Further, the central shaft 24 on which the radial partition plate 22 and the inverted L-shaped top plate 23 are integrally formed is assembled and integrated at the center of the lower surface of the lid 15 (the assembly structure is omitted in FIG. 3). When it is removed, the partition 17 can be removed from the main body 10 and maintenance and cleaning of the underfloor piping including the main body 10 can be facilitated.
[0047]
The lid 15 and the central shaft 24 are integrated as follows. As shown in FIG. 7 and FIG. 6B, a short shaft 30 is integrally projected at the center of the lower surface of the lid 15, and a pair of left and right elastic pieces 29 with check pawls are formed at the lower end of the short shaft 30. One key 28 extends in the axial direction in a direction orthogonal to these elastic pieces 29.
[0048]
On the other hand, the central shaft 24 is provided with a notch 25 'in the axial direction from the upper end of the pipe, and a constricted locking portion 28 is provided at the upper end, and the key 28 is fitted into the notch 25'. The lid 15 and the central shaft 24 are prevented from rotating, and the pair of elastic pieces 29 are deformed by resin so as to exceed the constricted locking portion 28 and engage the claw with the constricted locking portion 28. Combine them together to prevent them from coming off, and as a whole, assemble them as a single unit.
[0049]
Therefore, the partition 17 and the lid 15 are separated from each other to facilitate the synthetic resin injection molding.
[0050]
Here, since the notch 25 'is formed to be slightly long, the pipe-shaped central shaft 24 of the lower opening communicates with the inside and outside of the pipe even when the key 28 is fitted.
[0051]
For this reason, if this notch 25 'becomes a reflux port and drainage flows in from a full flow from one of the inlets (12), there is a risk of forming a vacuum in the assembly 4 and other inlets. Since the trap (sealed water) on the upstream side of 12 is easily destroyed, the air in the assembly 4 is circulated in the main body 10 as indicated by the arrow C in FIG. 7 (or the reverse direction of the arrow C). Prevents vacuum.
[0052]
Of course, the lid 15 and the partitioning body 17 are not integrated, but the vertical outer end of the radial partition plate 22 of the partitioning body 17 is fitted by two vertical protrusions protruding from the inner surface of the main body 10. The partition body 17 may be assembled by being fitted in the groove.
[0053]
2 and 4, reference numeral 26 denotes a pair of locking rods integrally formed on the upper edge of the main body 10, and the flange of the lid 15 is detachably attached to the locking rods 26 by bayonet coupling. Install.
[0054]
In addition, although the collective of this example (meeting house) is used for collective collective drainage equipment in underfloor piping, the present invention is not limited to this, and can be applied to other general residential drainage. It can also be applied to drop drops with the outlet facing down.
[0055]
【The invention's effect】
According to the present invention, since each opening or two openings of the plurality of inlets are partitioned by the radial partition plate and the top plate, it is possible to prevent the backflow of drainage to other inlets. Since splashing and scattering can be prevented by collision, a large number of inlets can be provided in a single assembly, which can be convenient for unitization of underfloor piping.
[0056]
In particular, since a partition body made up of a partition plate and a top plate is further installed in the main body, it is possible to form many bundles independent of the inflow port, thereby making the main body more compact and so-called header-type assembly. It becomes the same as the height of the road, and therefore the height of the main body can be made lower.
[0057]
Furthermore, since the two inlets are provided on substantially the same plane in each of the three sides except the outflow side, the height of the main body can be further reduced even if a large number of inlets are provided.
[0058]
Of course, it is convenient for under-floor piping as compared to a header type that is long in the axial direction of the drainage main pipe without taking a place for installation.
