Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a piping member for an elongated vent pipe and a piping structure connected to the elongated vent pipe.
[0002]
[Prior art]
In the drainage pipe system adopted in multi-storey buildings such as apartment buildings, drainage collection pipes are installed corresponding to each floor for standing main pipes that run vertically through each floor. A lateral branch pipe for each floor is connected via the pipe.
By the way, it is necessary to connect a vent pipe (this vent pipe is referred to as “extended vent pipe”) to the upper end portion of the standing main pipe for air intake. Therefore, it suffices to connect an extended vent pipe directly above the standing main pipe.
[0003]
However, in multi-story buildings, the top floor often has a layout (layout) that is different from other floors, for example, as an owner room or observation room. There was a case where piping that penetrated was not possible.
In such a case, the upper end of the standing main pipe is stopped at the floor slab level of the top floor, and a dedicated pipe member different from the drainage collecting pipe used in the above-mentioned other floor section is used for this section. It has been practiced to connect a lateral branch pipe and connect an elongated vent pipe to this piping member (see Japanese Patent Application Laid-Open No. 2000-273926).
[0004]
This conventional piping member has a pipe body provided at the intersection of the standing main pipe and the side branch pipe, and a lower joint part for connecting the standing main pipe is provided on the lower side of the pipe main body. The part is provided with a horizontal joint part for connecting a lateral branch pipe and a horizontal joint part for connecting an extended vent pipe, and the upper part of the pipe body is a closed top end part.
[0005]
[Problems to be solved by the invention]
In a drainage pipe system in which an extension vent pipe is connected using a conventional piping member, even if drainage from the side branch pipe for the uppermost floor flows into the extension vent pipe, the extension pipe should be extended. In order to prevent the drainage from overflowing from the top vent pipe, a drainage gradient should be provided so that the pipe member side is downstream of the horizontal pipe connecting the pipe member and the extended top vent pipe. It was obligatory.
However, although the drainage does not overflow from the extended vent pipe, if the drainage flows into the horizontal pulling pipe, dirt from the drainage will adhere to the inside of the pipe.
[0006]
And if this drainage is toilet drainage or the like, or if the drainage of the drainage is repeated and dirt adheres to it, the inner diameter of the horizontal pulling tube or the elongated ventilating tube may be reduced. .
In this case, the amount of air taken in from the extended vent pipe is limited and insufficient, and in the worst case, air is not taken in, which may cause a drainage trouble such as running out of sealed water.
The present invention has been made in view of the above circumstances, and is a piping system or the like in a case where an extended vent pipe cannot be connected to an upright main pipe directly above the standing main pipe. An object of the present invention is to provide a piping member for an extended vent pipe and a piping structure of the extended vent pipe that can prevent drainage from the pipe or the like from flowing in, and that does not interfere with air intake by the extended vent pipe. And
