Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention proposes a multi-instrument drainage system mainly applied to a new drainage method.

[0002]

2. Description of the Related Art A drainage system for an apartment house or a detached house usually has a drainage stack (hereinafter referred to as a stack).
The drainage from the plumbing equipment on each floor such as kitchen and wash basin is connected to the drainage pipe (hereinafter referred to as horizontal drainpipe), with a slight slope to the vertical pipe, and the joint at the junction (hereinafter the joint). ) And joined on the same floor as the plumbing fixture. The joint at the junction uses a large capacity, and particularly requires a large horizontal cross-sectional area. For this reason, the joint was heavy and expensive. In addition, a large space is required, and the degree of freedom in design tends to be lost.

That is, in a conventional drainage system, drainage from a plumbing fixture is merged with that of another plumbing at the same level, and the drainage horizontal pipe is conveyed in an open channel flow by a pipe gradient. Therefore, the horizontal drainage pipe must be thick and obey the standard gradient, which is a bottleneck in construction planning. And even if water leaks due to clogging or aging of the drainage horizontal pipe, it can not be repaired unless the interior of the building is destroyed, and replacement of the drainage horizontal pipe will have to be interrupted and enormous cost burden .

In other words, the vertical velocity component of the fluid flowing in the drain horizontal pipe is extremely small, and at the junction with the vertical pipe, the fluid occupied by the fluid in the horizontal drain pipe has a very large pipe cross-sectional occupancy. The airflow resistance at the time of merging with the flowing fluid becomes abnormally large. For this reason, interference with the fluid flowing through the vertical pipe, which occurs when the fluids flowing through the horizontal drain pipe merge, causes an increase in negative pressure inside the pipe, which causes trap opening and abnormal noise. These drawbacks are basically that the vertical velocity of the fluid flowing in the vertical pipe passing through each floor and the vertical velocity component of the laterally flowing fluid that is drainage from various instruments at each floor are combined at the junction or joint. The reason for this is that a large difference is caused in the negative pressure, which results in the trap being opened and an abnormal sound being generated. For this reason, it was necessary to increase the size of the joint, which also increased the cost. In addition, if the trap is opened, the properness as a sanitary facility is lost, and a heavy burden is imposed on maintenance.

In view of the above-mentioned conventional techniques, the present inventor has proposed a new technique in which the flow of the fluid in the horizontal drain pipe is made to be a full-flow pressure and siphon flow. That is, the content of the proposal is a drainage system including a standing pipe penetrating through each floor, a drainage horizontal pipe led from a plumbing device on each floor, and a joint directly connecting the standing pipe to the standing pipe. Is lowered below the level of the drainage floor slab, the vertical velocity component is sufficiently imparted to the fluid in the horizontal drainage pipe, and then combined with the fluid in the vertical pipe.

In the above-mentioned proposed technique, the drainage from each plumbing device is performed in an independent horizontal pipe, and a vertical velocity component is increased with the fluid in the vertical pipe, so that the so-called ventilation resistance is remarkable. It has been reduced. For this reason, the negative pressure generating action in the pipe is extremely reduced as compared with the conventional drainage system. Since the fluid in the horizontal drain pipe becomes a full flow due to the siphon phenomenon, it may be a relatively thin pipe, and there is no need to provide a gradient toward the vertical pipe, in other words, it has a slight reverse gradient. Even in such cases, drainage is sufficiently possible.

More specifically, the drainage from each appliance is individually connected to a flexible pipe (drain horizontal pipe), which is placed on a floor slab and connected to a joint at a level below each floor. Things. Thus, flexible tubing is initially bent horizontally and then vertically bent. For this reason, the fluid in the flexible pipe merges with the fluid in the standing pipe at a high speed full flow. That is, since the vertical velocity component of the fluid in the flexible pipe is merged by being accelerated more than in the conventional system, the ventilation resistance at the junction with the riser fluid is significantly reduced.

[0008]

SUMMARY OF THE INVENTION The present invention is intended to further improve the above-mentioned proposed drainage system. Specifically, the present invention relates to a method for joining drainage in a horizontally placed flexible pipe to a vertical pipe. , The pipes of the vertical section are bundled to form a pipe.

[0009]

SUMMARY OF THE INVENTION The gist of the present invention is to provide a drain stack penetrating through each floor, an instrument drain horizontal pipe led from a plumbing device on each floor, and a pipe for joining the instrument drain horizontal pipe to the drain stack. In a drainage system consisting of a vertical pipe and a junction that connects the vertical pipe to the drain stack, a plurality of vertical pipes are bundled and usually attached to the drain stack in this state, and the level of the junction is drained. The present invention relates to a multi-instrument drainage system which lowers the level below the floor slab and then joins the fluid in the drain stack.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, the present invention relates to a new technique for making a fluid flow in a drain horizontal pipe a full stream by pumping and siphon flow, that is, by bundling vertical pipes connected to the horizontal drain pipe. Specifically, it is composed of a standing pipe penetrating each floor, a drainage horizontal pipe led from a plumbing device of each floor, a vertical pipe extending from this, and a joint for directly connecting this to the standing pipe,
A drainage system in which the level of the joint is lowered from the level of the drainage floor slab and the vertical velocity component is sufficiently imparted to the fluid in the horizontal drainage pipe, and then combined with the fluid in the vertical pipe. It is performed in independent drain horizontal pipes, and increases the vertical velocity component to join the fluid in the vertical pipe.The fluid in the horizontal drain pipe becomes a full flow due to the siphon phenomenon. In addition, there is no need to provide a gradient toward the standing pipe. Conversely, drainage is sufficiently possible even with a slight reverse gradient.

The joint is provided at a level which is lower than the horizontal drain pipe by one floor, such as an apartment house, and the drain pipe is less than 45 degrees, preferably less than 15 degrees, most preferably. Is a vertical drainage pipe connected to a joint.

Basically, the horizontal drain pipes connected to the appliances are each independently connected to the vertical pipe and connected to the joint of the standing pipe. Such drain horizontal pipes preferably have the same diameter. Preferably, it is a flexible resin tube such as a polybutene tube. The horizontal drain pipe is generally placed on the floor slab without any gradient.

Now, a vertical pipe is arranged with respect to the drain horizontal pipe. In the first example, the vertical pipe from the drain horizontal pipe extended from each device is bundled, and usually, the vertical pipe is attached to the vertical pipe in this state. Preferably, the vertical tube is housed in an outer cylinder. In this case, the vertical pipe was bundled separately from the drain stack (in the form of a cylindrical multi-core pipe). In the second example, the vertical pipe is wound and bundled around the drainage stack, and effective use of space is achieved. In any case, if the vertical tube is, for example, a flexible resin tube (in the form of a flat blind tube) in which a part of the outer peripheral surface is connected in the longitudinal direction, the vertical tube has this connection portion. The vertical pipe can be wound up and bundled, and its workability is extremely easy. Of course, the structure takes into account the beautification of the appearance after piping.

That is, the vertical pipes which are relatively easy to be separated are put together here. In the first example, about 5 to 7 pipes are bundled in advance, and the It exhibits features such as ease of use, uniformity of construction, ease of maintenance, and cost reduction.
In addition, when the number of water supply devices is increased, if the number of bundled bundles is large, it can be dealt with immediately. In the first example, the vertical pipe is usually installed in a vent pipe provided side by side with the drainage stack, but in the second example, the vertical pipe is directly wound around the drainage stack. This is advantageous in terms of space and workability. Particularly in this example, if the vertical pipe has a structure in which a part of the outer peripheral surface is connected in the longitudinal direction, the vertical pipe can be wound around the standing pipe in a band shape and bundled. Becomes extremely easy.

The horizontal pipe and the vertical pipe drained from the appliance do not need to have a large capacity because basically independent flexible pipes are used. For example, a polybutene pipe having a diameter of 20 mm is sufficient. The connection to each instrument is sufficient with this one type of tube, so the operational advantage is much greater. The horizontal drainage pipe and the vertical pipe may be connected via a bent pipe, or the drainage horizontal pipe may be used as a vertical pipe as it is, that is, as a whole. In particular, a one-touch connection method described later has been developed for polybutene pipes, and it is optimal to use this method for these connections.
