Description

  The present invention relates to a water collecting basin used in a drainage system for guiding drainage from drainage equipment in a building to a drainage main pipe outside the building.

BACKGROUND OF THE INVENTION
For example, in a house, a building (2) is built in the site (1) as shown in FIG. 18, and a toilet (3), a kitchen (4), a bathroom (5), a washbasin are built in the building (2). Drainage facilities such as the place (6) and washing machine (7) are installed. Drainage from such drainage equipment is discharged from the drainage branch pipe (8,8A) in the building (2) to the drainage main pipe (9) in the building (2) outside site (1) through the house (10). However, the wastewater from the toilet (3) and kitchen (4) is mixed with filth or oily viscous materials, so the drainage pipe (8) is directly connected to the house to minimize the piping ( 10), the waste water from the bathroom (5), the washroom (6), and the washing machine (7) is not mixed with filth and viscous materials. The water is collected in the drainage basin (11) and discharged from the drainage branch pipe (8) to the drainage main pipe (9) via the basin (10).
The drainage pipe (9) is in contact with the public (17) outside the site (1).

[Conventional technology]
Conventionally, the water collecting tank (11) has a plurality of pipe connecting portions (13, 14, 15, 16) on the front and rear ends and sides of the main body (12) as shown in FIG. A structure with an inspection port (17, 18) is used, and each drainage device (5, 6, 6) in the building (2) is connected to the pipe connection (14, 15, 16) at the rear end and the side. The drainage branch pipe (8A) from 7) is connected, the drainage branch pipe (8) connected to the drainage main pipe (9) is connected to the pipe connection part (13) at the front end, and the inspection port (17,18) is the building The floor is opened and a lid is attached (see, for example, Patent Document 1 and Patent Document 2).

JP 2003-96857 A (see FIGS. 1 and 5) Japanese Patent Laid-Open No. 2002-106010 (see FIGS. 1 and 2)

  In the case of the conventional water collecting basin (11), the main body (12) has a trunk length, and the drainage branch pipe (8A) is connected from one side, so compact piping cannot be made, and piping work However, it is difficult to place it close to the corner of the building, and it is difficult to conceal it by opening the inspection port (17, 18) under the washing machine (7) etc. near the wall.

In the present invention, as a means for solving the above-mentioned conventional problems, the toilet (3) drainage and the kitchen (4) drainage of the building (2) drainage equipment (3,4,5,6,7) directly outside the building Introduced directly into the drainage main pipe (9), drainage from other building drainage facilities (5,6,7) merged with the water collection in the building (21) and then introduced into the drainage main pipe (9) outside the building The drainage system (21) includes a main body (22), a plurality of upstream pipe connecting portions (24, 25, 26) that are extended laterally from the main body (22), and one The downstream pipe connection portion (23) and the inspection port (27) that extends upward from the main body (22), and each upstream pipe connection portion (24, 25, 26) has a toilet (3) and Drain branch pipes (8A) from the drainage facilities (5, 6, 7) in each building other than the kitchen (4) are connected, and the downstream pipe connection (23) is connected to the main drain (9) outside the building. Drainage from the drainage system in the building (5,6,7) connected to the drainage branch pipe (8) Depending diameter is set, the diameter of the downstream-side pipe connecting portion (23) is to provide a Masu catchment that is set to the maximum (21).
The plurality of upstream side pipe connecting portions (24, 25, 26) are preferably provided radially outward from the body (22) of the water collecting tank (21).
Further, the drainage branch pipe (8A) is preferably a flexible pipe in which convex ring portions (81A) and concave groove portions (82A) are alternately arranged, and a building other than the toilet (3) and kitchen (4). The internal drainage facilities are the bathroom (5), the washroom (6), and the washing machine (7), and the upstream pipe connection (24) that communicates with the bathroom (5) is the washroom (6) and the washing machine (7). It is desirable that the diameter is set larger than that of the upstream side pipe connecting portions (25, 26) communicating with the downstream side pipe connecting portion (23).
Further, a flat partition plate (44) is connected to the bathroom (5) in the central portion of the water collecting main body (22), and the pipe shaft of the upstream side pipe connection part (24) and the downstream side pipe connection part (23). It is arranged parallel to the line L connecting to the tube axis, or a V-shaped partition plate (42) in the central part in the water collecting body (22), and the closed end is connected to the downstream pipe connecting portion. It is desirable that it is arranged toward (23) and toward the upstream pipe connection (24) that connects the open end to the bathroom (5).
Furthermore, it is desirable that an inspection tube / drain pipe (33) is connected to the inspection port (27) of the main body (22).

  In the water collecting tank (21) of the present invention, the pipe connecting portion (23, 24, 25, 26) is extended from the main body (22) to the side, so that the main body (22) is cylindrical. Therefore, it is easy to place it at the corner of the building (2). Therefore, the inspection port (27) can also be opened on the floor of the corner of the building (2), and the inspection port (27) is concealed by a washing machine (7), etc. placed at the corner of the building (2). I can do it.

In addition, the pipe connection parts (23, 24, 25, 26) of the water collecting basin (21) are calibrated according to the amount of drainage from the drainage facilities (5, 6, 7) in the building, and the water collection Since the diameter of the downstream pipe connection (23), which is the first (21) outlet, is set to the maximum, drainage from the drainage system (5,6,7) in the building collects smoothly ( It flows into 21) and is discharged.
In particular, the upstream pipe connection part (24) into which the drainage from the bathroom (5) having the largest drainage is introduced in the drainage equipment (5, 6, 7) is the other upstream pipe connection part (25, 26). Since it has a larger diameter and is opposed to the downstream side pipe connection portion (23), the inflow and discharge of the drainage into the water collection port (21) is performed smoothly.

At this time, the flange (29A) provided on the inner periphery of the front end of the fixing tool (29) locks the fixing ring (30) attached to the concave groove (82A) of the drainage branch pipe (8A). Prevent drainage branch pipe (8A) from coming off.
A straight tubular drain branch (8) is connected to the downstream pipe connection (23).

  As shown in FIG. 4, the water collecting basin (21) is supported at a predetermined height from the foundation (31) by bolts (32, 32) through the base (28) under the floor, and the inspection port (27). The inspection tube (33) is connected to the upper surface of the inspection tube (33), and the upper end of the inspection tube (33) is made to coincide with the floor surface and the lid (34) is attached. On the downstream side, if desired, a T-shaped pipe joint (35) is connected to the downstream end of the drainage branch pipe (8A), and the tip end of the T-shaped pipe joint (35) has a tip. A vent pipe (36) having a vent valve (not shown) is connected to the drainage trap to prevent water breakage of each drainage facility side trap. And the drainage branch pipe (8) is connected to the lower end of the T-shaped pipe joint (35) through a 90 ° bend joint (37), and the drainage branch pipe (8) is in the house outside the building ( Contact 10). Although not shown, when the drainage branch pipe (8) penetrates the building foundation, a foundation penetration sleeve is embedded in the foundation, and the drainage branch pipe (8) is inserted into the sleeve.

  In the above configuration, since the water collecting basin (21) is compact, it can be arranged close to the corner of the building (2) to open the inspection tube (33) at the wall. Since the washing machine (7) or the like is usually installed near the wall, if the inspection tube (33) is opened near the wall, the washing machine (7) can be placed thereon to conceal the opening.
