Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a piping structure for a sewage pipe that is led from a building to an underground sewage main pipe.

[Conventional technology and its problems]

Since sewage pipes that carry sewage from homes and the like to the main sewage pipes allow sewage to flow down naturally, the slope of the pipes is particularly important. However, when installing branch pipes to the main sewage pipe buried along buildings, etc., it is difficult to ensure the accuracy of the slope, and if the ground is particularly soft, the slope may become distorted due to subsidence, making it difficult to properly drain the sewage. It may become impossible to plan for natural flow. For this reason, in the past, piping from homes, etc. was not led directly to the main sewage pipe, but instead, as shown in Fig. A cell 18 is provided in the main sewer pipe, and by selecting the connection position (height) of the sewage branch pipe 3' to this cell 18, the sewage can flow in the direction of the main sewer pipe even if the slope accuracy of the pipe itself is not very high. There is. However, this cell 18 has the disadvantage that it takes time and effort to construct and increases the cost of piping.

The present invention was devised in view of these conventional difficulties, and aims to provide a structure that allows sewage to properly flow down naturally, without the need for a basin, due to an appropriate slope.

[Means to solve the problem]

Therefore, the present invention has the following configuration.

A drain pipe 2 from inside the building is directly connected to a sewage branch pipe 3 to be buried underground.

In order to support this sewage branch pipe 3 underground, a mounting portion 7 has a plurality of mounting holes 12 for anchor bolts and is to be fixed to the upper surface of the building foundation by an anchor bolt 9 inserted through the mounting holes 12. , a first support component A having a plurality of bolt mounting holes 12A in the vertical direction and a connecting part 13A vertically installed from the mounting part 7, and a pipe support on the upper surface to support the pipe. 8 and a plurality of bolt mounting holes 1 in the vertical direction.
2B, and a connecting portion 13B connected above the piping support portion 8;
Connect the connecting portion 13B of the second support component B to the connecting portion 13A of the
A plurality of piping supports 5 are used which are configured to be connected at any height in the vertical direction via 2A, 12B and fastening bolts 14 attached thereto.

That is, the connecting portion 1 of the first support component A
Connection part 1 of second support component B to 3A
The plurality of pipe supports 5 having different heights of the pipe support parts 8 depending on the selection of the mounting positions of the pipes 3B are mounted and fixed to the building foundation 6 at appropriate intervals, and the sewage branch pipe 3 is connected to the plurality of pipe supports 5. By being supported by the piping support 5, the piping is installed along the building foundation 6 at a predetermined slope.

Furthermore, an upright pipe 10 whose upper end reaches the ground surface is connected to a suitable location of the sewage branch pipe 3.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention, in which 1 is a building, 2 is a sewage drain pipe led from the building 1, and 3 is a sewage branch pipe. It is led to a sewer main (not shown).
Moreover, FIG. 4 is an exploded perspective view of the piping support 5 used in FIGS. 1 to 3.

The present invention is characterized in that the sewage branch pipes are led to the main pipe without using a square, and for this reason, each drain pipe 2 is directly connected to the sewage branch pipe 3 via a joint 4. In order to enable a structure that does not use such a cell, in the present invention, the sewage branch pipe 3 is supported on the foundation 6 of the building at a predetermined slope via a pipe support 5.

The height of the support part 8 of the pipe support 5 needs to be changed according to the height at which the pipe is to be supported, and therefore, as shown in FIG. A first support component A having a mounting part 7, a plurality of bolt mounting holes 12A in the vertical direction, and a connecting part 13A connected to the mounting part 7 below, and piping on the top surface. A second support component B that includes a pipe support part 8 to support the pipe support part 8, and a connecting part 13B that has a plurality of bolt attachment holes 12B in the vertical direction and is connected to the support part 8 above the support part 8. These support component members A and B are connected to arbitrary bolt mounting holes 12A and 1 of both of them.
2B and a plurality of fastening bolts 1 attached to it
By connecting via 4, the height of the pipe support part 8 can be adjusted.

Such a plurality of piping supports 5 have their mounting portions 7 in contact with the upper surface of the base portion 6 and anchor bolts 9
By fixing them, they are attached and fixed at appropriate intervals along the foundation 6, thereby supporting the sewer branch pipe 3 along the building foundation 6. The height of the pipe support part 8 of each pipe support 5 is selected according to the height at which the sewage branch pipe is to be supported, and the slope is such that the support position of the sewage branch pipe 3 gradually becomes lower toward the main sewage pipe. The sewer branch pipe 3 is supported as shown in FIG.

Further, an upright pipe 10 reaching the ground surface is provided at a suitable location of the sewer branch pipe 3, so that even if clogging with solid matter or the like occurs, it can be dealt with. That is, according to the present invention, troubles in the piping can be dealt with only by using the standing pipe without providing a cell or the like.

In each of the embodiments described above, a locking part 81 is provided protruding from the tip of the pipe support part 8 to prevent the supported pipe from coming off.

In addition, the sewage branch pipe 3 supported by the pipe support part 8
It is preferable to fix it to the support part by, for example, a stop band 15 consisting of a U-shaped member 16 and a nut 17, as shown in FIG.

The piping structure of the present invention uses the above-mentioned supports to pipe the sewage branch pipe 3 along the building 1 at a predetermined slope, and after such piping is completed, it is backfilled with earth and sand.

In each of the embodiments described above, the mounting portion 7 is fixed to the upper surface of the base 61 (footing) of the foundation portion 6 via the anchor bolt 9. part 6
It may be fixed to the side of 2 with an anchor bolt.

[Effect of idea]

According to the present invention described above, since the sewer branch pipe is supported on the foundation of the building by the plurality of pipe supports 5 whose heights can be adjusted, the pipe slope can be ensured with high accuracy. , it is possible to install sewer branch pipes without installing a conventional cell. Furthermore, even if a standpipe installed at an appropriate location of a sewage branch pipe becomes clogged with solid matter, it can be dealt with in the same way as with the conventional square system. In addition, the construction is as simple as attaching the pipe support to the foundation using anchor bolts and placing the sewage branch pipe on top of the support, which reduces the need for construction of the cell. It has the great advantage of being able to perform construction with less time and cost.

In addition, since the mounting portion 7 of the pipe support 5 comes into contact with the upper surface of the building foundation and shares the pipe support function with the anchor bolt, it is possible to securely hold large diameter and heavy pipes. It is possible to appropriately prevent piping from sinking even on soft ground.
