Description

DETAILED DESCRIPTION OF THE INVENTION The present invention connects the upper end of the intermediate joint pipe, which is formed by vertically connecting the sewage swirl control reduction part that bulges out to the outer circumferential side, to the lower end of the drainage vertical pipe at the middle of the floor height. At the same time, a sewage or gray water branch pipe is branched out from the lower end of the intermediate joint pipe, and the lower end of the branched part of the sewage or gray water branch pipe in the intermediate joint pipe is connected to the lower end of the branch pipe located above the floor. This relates to a drainage pipe system in a building that is characterized by being connected to gray water or sewage branch pipes at the upper ends of floor drainage vertical pipes, and its purpose is to connect the drainage vertical pipes and horizontal branch pipes. An improved glance-type drain pipe that slows down the flow of flowing sewage, reduces internal pressure fluctuations due to flowing sewage, water level fluctuations of various devices and pipe traps, water level fluctuation losses, etc., and allows smooth drainage and ventilation. The point is to provide equipment.

The flow rate of wastewater in a vertical pipe reaches its maximum speed at 4 to 7 points. Therefore, it is necessary to efficiently slow down the flow rate before reaching the maximum speed by adjusting the pressure fluctuation value in the pipe, each device, and the pipe trap. This is effective in reducing water level fluctuation values, water level fluctuation loss values, etc.

In the present invention, as described above, an intermediate joint pipe is used in which a swirling flow control section that bulges out to the outer circumference is vertically installed, and each of its upper and lower ends are connected to the middle part of the floor height. And on the floor, connect the lower end of the drainage vertical pipe and the sewage or gray water branch pipe branch, and connect the branch to the gray water or gray water branch pipe at the upper end of the lower floor drainage vertical pipe installed above the floor. Since it is connected to the branching part, the flowing sewage in the upper drainage vertical pipe enters the intermediate joint pipe at the middle part of the floor height before reaching the maximum flow velocity, and is continuously connected in the vertical direction of the joint pipe. It flows down while being decelerated along the tube wall of the swirling flow control deceleration section that bulges out to the outer circumferential side.

After deceleration, there is no swirling flow, and the flow is flowing vertically along the pipe wall.In other words, according to the present invention, the distance of the wastewater flowing down the vertical pipe is short (because the deceleration parts are arranged in a distributed array). , the flow rate is effectively reduced, and when the swirling flow sewage flows into the concentric concave joint on the outer circumference side, a splashing action occurs along the pipe top, and this process is repeated to reduce the speed. A part of the water flows down on top of the splashed water flow and is decelerated, and by appropriately selecting the location of the rotation control deceleration part between each floor and the intermediate part of each floor, the water flow can be efficiently reduced. The fluctuation value of the pressure inside the pipe by slowing down the water, and each equipment,
It is possible to suppress the water level fluctuation value of the pipe trap, the water level fluctuation loss value, etc. Further, according to the present invention, as described above, the gray water branch pipe and the waste water branch pipe are branched or connected from the intermediate joint pipe and the drainage vertical pipe, respectively, and the two branch pipes are separated from each other. By adjusting the relative rotation of the intermediate joint pipe and the drainage vertical pipe, each of the branch pipes is arranged to extend in a desired direction, thereby facilitating the piping work.

In addition, in manufacturing, etc., planned production is possible, and productivity is good in terms of shape, so material costs are low. Note that each of the branch pipes also acts as a deceleration section for flowing sewage water. Furthermore, in the present invention, since the main body of the drainage vertical pipe passes through the building frame, the present invention has many advantages, such as the diameter of the vertical pipe penetrating portion in the building frame is reduced to a small diameter.

The present invention will be described below with reference to the illustrated embodiments.

1 is a drainage vertical pipe in a building, 3 penetrates the same floor 2,
A gray water joint protrudes above the floor, to which a gray water branch pipe 4 is connected via a joint receiving portion 3' extending outward from the upper end.

In the intermediate joint pipe 5, swirling flow control deceleration parts 6 each made of a rotating curved body that bulges toward the outer periphery are arranged in a row at predetermined intervals.
A joint part 7 is connected to the outer side near the lower end, and a sewage branch pipe 8 is connected via a joint receiving part 7' extending outward.

The upper end of the intermediate joint pipe 5 is connected to the lower end of the drainage vertical pipe 1 at the middle part of the floor height, and the lower end is connected to the lower sewage joint part 7 or between 5 and 7 on the floor 2. It is connected to the upper end of the lower standpipe.

At this time, by adjusting the relative rotation angle between the gray water joint 3 and the sewage joint 7, the branch pipes 4 and 8 can be arranged to extend in a desired direction. Since the drain pipe device according to the present invention is configured as described above, the waste water flowing down the drain vertical pipe 1 enters the intermediate joint pipe 5, and passes through the swirl flow control deceleration parts arranged vertically. It flows down sequentially, and the flow rate is reduced in between.

In this way, the generation of negative pressure and positive pressure within the drain pipe is prevented, and fluctuations in the pressure inside the pipe, fluctuations in the water level of each device and pipe trap, loss due to water level fluctuation, etc. can be reduced. Further, each of the branch pipe receiving parts 3 and 7 also acts as a deceleration part for flowing sewage water. Although the present invention has been described above with reference to embodiments,
The present invention is, of course, not limited to such embodiments, but can be modified in various ways without departing from the spirit of the invention.
