Description

    The present invention relates to a water supply / drainage structure in a multi-layered building, and more particularly, to a water supply / drainage structure in a multi-layered building in an apartment building, a training camp or an accommodation facility such as a hotel in which rooms are arranged side by side on at least one side of a corridor. .

  For example, in a hotel, guest rooms are arranged in parallel facing the corridor, and water and hot water for bathtubs, washstands, and toilets that are arranged in each guest room are supplied to pipe spaces that are located adjacent to each guest room.・ Equipped with a valve for hot water supply so that each guest room can be maintained and managed, and drainage from the bathtub, wash basin and toilet placed in each guest room is drained from the bathtub, wash basin and toilet respectively. Is connected to a drainage main pipe penetrating vertically in the pipe space.

  In this case, the pipe space is secured as a sufficiently large space so that various operations can be performed inside.

  However, in a water supply / drainage facility such as a hotel, since the number of rooms is large, when the pipe space is arranged adjacent to each guest room, the ratio of the floor area of the pipe space to the floor area on each floor increases. This pipe space is a dead space when viewed from the entire building, and it is desired that this pipe piping space be formed small.

  The present invention has been made by paying attention to such a point, and it is possible to make the occupied space of the pipe space small so that the volume of the living room space can be widened. An object of the present invention is to provide a drainage structure capable of easily cleaning a drainage main pipe.

  In order to achieve the above-mentioned object, the present invention arranges a water supply main pipe and a hot water supply main pipe in a corridor ceiling back portion of each floor, and arranges a valve unit having a plurality of valve openings in each of the water supply main pipe and the hot water supply main pipe, A water supply branch pipe and a hot water supply branch pipe for each room are branched into the valve unit, and a drain main pipe vertically disposed in a state of passing through each floor, and a drain branch connected to the drain main pipe A drainage system is constructed with the pipe, 45 degree Y-shaped pipe joints are arranged at regular intervals in the drainage main pipe, and a water droplet scattering prevention device made of chrysanthemum rubber is fitted to the branch pipe part of this 45 degree Y-shaped pipe joint. In addition, it is characterized in that the end portion of the water droplet scattering prevention device made of chrysanthemum rubber can be closed with a cap member.

  In the present invention, a water supply main pipe and a hot water supply main pipe are arranged in the back of the corridor ceiling of each floor, a valve unit having a plurality of valve ports is arranged on each of the water supply main pipe and the hot water supply main pipe, and water supply to each room is provided in each valve unit. Branch pipes and hot water branch pipes are respectively branched, and 45 degree Y-shaped pipe joints are arranged at regular intervals in a drainage main pipe that is arranged vertically through each floor. A water supply / hot water supply system has been constructed so that a water drop splash prevention device made of chrysanthemum rubber is fitted to the branch pipe part of the fitting and the end of the water drop splash prevention device made of chrysanthemum rubber can be closed with a cap member. It is not necessary to place the pipe in the pipe space that is placed adjacent to each room, and even if the cleaning liquid sprayer is inserted into the drain main pipe to clean the drain main pipe, the cleaning liquid will be scattered and the corridor side No longer get dirty. As a result, the pipe piping space that accommodates the drainage main pipe does not require a so-called work space, so that only a minimum volume is required, and the living room space can be widely formed.

FIG. 1 shows an embodiment of the present invention, FIG. 1 is a schematic system diagram showing a main part extraction showing a water supply / hot water supply system in a hotel where a large number of rooms are arranged side by side across a corridor, and FIG. FIG. 3 is an enlarged schematic view of the main part of the drainage main pipe.
This water supply / hot water supply system has a water supply main pipe (2) and a hot water supply main pipe (3) in the upper space of the ceiling part of the corridor (1). There are valve units (4) and (5) for water and hot water supply, respectively. In this valve unit (4) and (5), a hot water supply branch pipe (6) and a water supply branch pipe (7) are connected in communication so that hot water and water can be distributed to a plurality of rooms (6 rooms in the figure) adjacent to each other. The hot water supply branch pipe (6) and the water supply branch pipe (7) are connected to each room as a pair, and the bathtub (8), the wash basin (9), and the toilet bowl are arranged in each room. In (10), water and hot water can be supplied.

  On the other hand, drainage from the bathtub (8), the washbasin (9), and the toilet bowl (10) arranged in each room is led out from the bathtub (8), the washstand (9), and the toilet bowl (10). Each drain pipe (8a), (9a), (10a) was joined to a drain branch pipe (11) arranged horizontally in the horizontal direction, and formed at a location facing the corridor between two adjacent rooms. The drainage branch pipe (11) is connected in communication with a drainage main pipe (12) arranged in a standing manner in a state of penetrating each floor in the pipe space.

  In the drainage main pipe (12), 45 degree Y-shaped pipe joints (13) are arranged on a plurality of floors. The branch pipe part (14) of the 45 degree Y-shaped pipe joint (13) is shown in FIG. Branching pipe part (14) of 45 degree Y-shaped pipe fitting (13) fitted with chrysanthemum rubber water drop splash prevention tool (15) and fitted with chrysanthemum rubber water drop splash prevention tool (15) The end is closed with a cap member (16) so that it can be opened and closed. And the branch pipe part (14) of this 45 degree Y-shaped pipe joint (13) is accommodated in the pipe space in a state of being located on the corridor side, and the branch pipe part of this 45 degree Y-shaped pipe joint (13). (14) is formed at the cleaning port of the drain main pipe (12).

  Thus, the water supply main pipe (2) and the hot water supply main pipe (3) are piped on the ceiling of the corridor (1), and the water supply main pipe (2) and the drain main pipe (3) are formed in a header shape having a plurality of valve openings. The valve units (4) and (5) are arranged respectively, and the hot water supply branch pipe (6) and the water supply branch pipe (7) connected to the valve units (4) and (5) are arranged in parallel facing the corridor. When piping is provided in each room, it is not necessary to secure a large volume of hot water / water supply pipe space in each room, so that the area on each floor can be used effectively.

  In addition, a 45 degree Y-shaped pipe joint (13) is arranged on the drain main pipe (12), and a water droplet splash prevention device (15) made of chrysanthemum rubber on the branch pipe part (14) of this 45 degree Y-shaped pipe joint (13). When the branch pipe part (14) is formed at the cleaning port of the drain main pipe (12), the washing water can be prevented from splashing even if a high-pressure washing instrument is used for cleaning. Therefore, the drainage main pipe (12) can be cleaned from the corridor side, and it is not necessary to secure a working space in the pipe space containing the drainage main pipe (12). It can be formed as small as possible, and the area on each floor can be used effectively.

  In the above embodiment, the water supply / hot water supply system and the drainage system in a hotel where a number of rooms are arranged side by side on both sides of the corridor have been described. It can be applied to water supply / hot water supply systems and drainage systems.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a water supply / hot water supply system and a drainage system in a building where a plurality of water facilities are arranged in parallel on at least one side of a corridor.

It is a principal part extraction schematic system diagram which shows the water supply and hot-water supply system in a hotel. It is a principal system outline schematic diagram which shows the drainage system in a hotel. It is a principal part enlarged view of a drainage main pipe. It is a top view of a water droplet scattering prevention tool made of chrysanthemum rubber.
