Description

[Detailed description of the invention] [Technical field] This invention is a drainage basin.More specifically, a connecting pipe is provided at the bottom of the basin body to connect to the main pipe, and a branch pipe socket can be attached to the right or left side at the bottom of the basin body. This concerns a small-diameter drainage basin.

[Background technology] Generally, a connecting pipe for connecting to the main pipe is provided horizontally at the bottom of this type of drainage basin. The wastewater is directed to the main pipe. The connection between the drainage basin and the main pipe is that both main pipes are connected straight through the drainage basin, or connected to one of the main pipes in a curved manner, or a branch pipe is connected to the drainage basin in a Y-shape. There are various connection methods depending on the site, such as connecting them in a shape, so in the past, there were many different types of drainage basins such as straight connection drainage basins, curved connection drainage basins, left and right Y-shaped drainage basins, etc. A drainage basin had to be prepared, which increased the cost of molds, and the large number of varieties made them difficult to handle.

[Purpose of the invention] The present invention was made in view of the above points, and by making it possible to install the branch pipe socket on the right or left side of the bottom of the main body, it is possible to use a single type of drainage pipe for various main pipes. The purpose of this project is to provide a drainage basin that can accommodate various methods of connecting branch pipes.

[Disclosure of the invention] That is, the drainage basin of the invention has a connecting pipe 3 connected to the main pipe 2 from opposite sides of the lower part of the basin main body 1, which is formed into a bottomed cylindrical shape with an open top surface.
branch pipes which protrude in a rib shape from both sides of the main body 1 at positions substantially perpendicular to the connecting pipe 3 and engage with the engaged portion 7 provided at the open end of the branch pipe socket 6. This device is characterized in that an engaging portion 5 for connecting the socket 6 is provided, and a punchable punching plate portion 9 surrounded by a thin wall portion 8 is formed on the inner peripheral side of the engaging portion 5. If you want to connect both the main pipes 2, 2 straight, leave the punched plate part 9 unpunched, and if you want to connect the branch pipe socket 6 by bending it in a Y-shape on the left or right, use either the left or right punched plate part. Punch out 9 and attach branch pipe socket 6.
The above object is achieved by connecting the main body 1 to the main body 1.

The present invention will be described in detail below based on illustrated embodiments. As shown in Figures 1 to 3, the square body 1
is constructed by connecting a cylindrical upper body 11 and a cylindrical lower body 12, and has a bottomed cylindrical shape with an open top. Connecting pipes 3 for connecting to the main pipe 2 extend outward from both opposing sides of the lower body 12, and connecting pipes 3 are provided on both sides 4, 4 of the lower body 12, which are approximately orthogonal to the connecting pipes 3, respectively. is the plane part 24,
24 are formed respectively. This flat part 24 has a rib-shaped engaging part 5 for connecting the open end of the branch pipe socket 6, and this engaging part 5 connects the horizontally long elliptical connecting part 13 to the flat part 24. The engaging piece 14 is formed to protrude further and is bent outward from the tip of the connecting part 13. The engaging piece 14 forms the engaging portion 5. In addition, connection part 1
A flat portion 24 at the inner edge of the pipe 3 is a thin wall portion 8 corresponding to the diameter of the branch pipe 21, and a portion surrounded by the thin wall portion 8 is a punched plate portion 9. Further, the outer surface of the connecting portion 13 forms a flush connecting surface 15. The bottom plate 16 of the lower body 12 is provided with an inclined surface 17 so that the peripheral edge is inclined slightly upward from the center. There is. 18 in the figure is the connection part 1
This is a guide portion that is provided continuously from the guide portion 3 to the side of the flat portion 4. On the other hand, as shown in FIG. 4, the branch pipe socket 6 is formed to be slightly bent, and a connecting surface 19 is formed flush with one end of the branch pipe socket 6. A U-shaped engaged portion 7 that opens toward the front is formed. The engaged portion 7 is formed of a slide groove 20 that opens inward, and one side of the slide groove 20 is open.

However, when the main pipe 2 is connected and buried in the ground in a straight manner, the punched plate part 9 of the main body 1
The ends of the main pipes 2, 2 are connected to both connecting pipes 3, 3 of the main body 1 while the main pipes 2, 2 are attached. In addition, when connecting the main pipe 2 and the branch pipe 21 in a Y-shape depending on the site, one of the two punched plate parts 9 is punched out and torn, and then As shown in Fig. 2, while engaging the slide groove 20 of the branch pipe socket 6 with the engagement piece 14 of the main body 1, slide the branch pipe socket 6 in the direction of its opening. It can be attached to. At that time, adhesive is applied to the connection surface 19 of the branch pipe socket 6 or the connection surface 15 of the main body 1 of the cell, and the connection surface 15 of the main body 1 of the cell 1 and the connection surface 19 of the branch pipe socket 6 are bonded together. be. This branch pipe socket 6 can be attached to either the left or right flat portions 4, 4 of the main body 1, and can correspond to either a left-handed Y-shape or a right-handed Y-shape. In this way, depending on the site, the main pipe 2 can be connected straight, or the branch pipe socket 6 and the main pipe 2 can be connected in a Y-shape, so when shipping products from the factory to the site. It is sufficient to attach only one branch pipe socket 6 to the main body 1 and ship it.

In the above embodiment, the side surface 4 having the engaging portion 5 for attaching the branch pipe socket 6 is replaced with the flat portion 24.
However, the engagement portion 5 is not limited to the flat portion 24, and may be formed on a curved portion.

[Effects of the invention] As described above, the present invention allows punching out the punched plate portions and connecting them in a Y-shape depending on the site situation, or connecting the main pipes straight without punching out the punched plate portions. Various types of connections can be made by preparing only the main body and branch pipe sockets, which has the advantage of saving mold costs and being easy to handle since there are few types. Moreover, the branch pipe socket can be reliably connected by the engagement between the engaging part and the engaged part, and since the engaging part protrudes in a rib shape, the branch pipe socket can be easily connected. If the connection part with the punched plate has a high strength, and a branch pipe socket is not connected, the presence of a thin wall surrounding the punched plate tends to cause problems in terms of strength. Since the protruding engaging portion is located on the outer periphery of the thin wall portion and provides reinforcement, there is no problem in terms of strength due to the presence of the thin wall portion.
