Description

  The present invention relates to a system for supplying water such as cleaning water or drinking water, hot water or water for heating to a guest room or the like on each floor in a multi-layer building structure such as a high-rise hotel.

Conventionally, as a system for supplying water such as cleaning water or drinking water, hot water or heating water to guest rooms on each floor of high-rise hotels, etc., pipes are suspended from an elevated water tank or boiler provided on the rooftop floor, The pipes are connected to branch pipes for supplying irrigation water to the guest rooms on each floor, and water for cleaning, drinking water, etc. from elevated tanks or boilers, and water for hot water or heating water is supplied to each floor through these pipes and branch pipes. Supplying to guest rooms etc. is done.
JP2000-240956

  However, in such a water supply system, the water pressure is high on the rooftop floor, and the water pressure is lowered as it goes to the lower floor. Therefore, the pipes are made of vinyl chloride pipes, metal pipes, etc. with large diameters in accordance with the high water pressure. However, since these pipes have large diameters and are rigid, there is a drawback that piping construction is extremely difficult.

  In view of the above circumstances, the present invention forms a circulating water channel on the upper floor of a multi-layered building structure, and provides a water supply pipe between the water supply device and the circulating water channel. Alternatively, the present invention proposes a water supply network piping system in a multi-layered building structure such as a high-rise hotel in which two or more distribution pipes are installed vertically and branch pipes for supplying water are connected to each floor.

  In this invention, a circulating water channel is formed on the upper floor of a high-rise hotel or the like, water is supplied to the circulating water channel through a pipe from a supply device, and the water circulating in the water channel is caused to flow down through a distribution pipe and further connected thereto. Supplied to each floor through branch pipes.

  That is, in the present invention, a circulating water channel is interposed between the water supply device and the distribution pipe, and the water from the supply device is once supplied to the circulation water channel and is then sent to the distribution pipe. Since the water pressure is kept constant, the diameter is small, and a flexible polybutene pipe or the like can be used, the construction of the pipe can be performed very easily.

  Circulating water channels may be provided at two locations on the upper and lower floors of the multi-layered building structure. In this case, the water supply is provided between the water supply device and one of the upper or lower floor water channels. And a return pipe for water is provided between the other circulating water channel on the upper floor or the lower floor and the water supply device, and further between the circulating water channel on the upper floor and the lower floor circulating water channel. One or two or more distribution pipes can be installed vertically, and a branch pipe for supplying water to each floor can be connected to the distribution pipe.

  In this case, the irrigation water is supplied from the supply device, for example, to the circulation channel on the upper floor, circulates in the water channel, and then flows down through the distribution pipes. Has been circulated.

  In this configuration, compared to a configuration in which a circulation channel is provided in one place on the upper floor, circulation channels are provided in two locations on the upper floor and the lower floor, and a distribution pipe is provided between the circulation channels on the upper floor and the lower floor. Since it is provided, the water pressure supplied to each floor through the branch pipe connected to the distribution pipe can be kept more constant.

  Examples of the water used in the present invention include washing water, drinking water, cold water for bathing, warm water, warm water for heating, and the like.

  In addition, examples of the water supply device include a water tank with a built-in circulation pump, a water supply unit, a hot water supply unit, and a heating boiler unit.

  That is, in this invention, since the water pressure passing through each pipe is kept constant, it is possible to use a polybutene pipe or the like having a smaller diameter and a flexible pipe as compared with the prior art. It can be done easily.

  In addition, the conventional water supply device used an elevated installation method that is installed on the rooftop of a high-rise hotel. However, in this invention, the water pressure flowing through the piping is kept constant by the circulation channel, so it is installed on the lower floor. Even so, it can perform its function sufficiently.

  Annular waterways are formed on the upper and lower floors of the multi-layered building structure, and water supply pipes are provided between the water supply device and one of the circulating waterways on the upper and lower floors. A return pipe for irrigation water is provided between the other circulation channel on the lower floor and the water supply device, and one or more distribution pipes are provided between the circulation channel on the upper floor and the circulation channel on the lower floor. A water supply network piping system in a multi-layered building structure in which a branch pipe for connecting water to each floor is connected to the distribution pipe.
