And a discharge valve that The damping water tank is provided with a water chamber for storing damping water and a gas chamber for introducing a damping gas that acts on the water surface of the water chamber. The parameters of the vibration system of the damping water tank are adjusted by using the gas pressure inside the pressure gas cylinder. The drain valve opens based on the gas pressure. The drain valve operates by the gas pressure of the cylinder, and the operation in emergency is certain. It is important that part of the damping water is supplied as cooling water to the emergency generator used in an emergency. It is advisable that the operation source for supplying the damping water to a necessary place in an emergency is not limited to the gas pressure. It is important to adjust not only the gas pressure but also the water level in the damping water tank to supply various types of water required for emergencies, such as emergency generators and fire protection water, with its own water pressure. For that purpose, a water level adjusting water supply valve for adjusting the water level in the damping water tank is further added, and the water level can be adjusted based on the opening of the water level adjusting water supply valve.

The parameter adjustment is the adjustment of the pressure of the gas chamber, and further the adjustment of the water level in the damping water tank. In this case, an additional emergency operating valve is added and the pressure in the gas chamber is generated by the pressurized gas cylinder via the emergency operating valve. Even if the electric system becomes inoperable due to an earthquake or fire,
The operating force for operating the drain valve to discharge the damping water as fire extinguishing water from the damping water tank is the pressure of the pressure gas cylinder that is permanently installed, and the probability that such operating force is lost is small. The vibration-damping gas is not limited to air, and nitrogen gas that is effective in a fire can be used suitably. The operating pressure preferably acts on the gas chamber in the event of a fire. More preferably, the operating pressure is higher than the damping pressure. It is important to reliably supply the cooling water for cooling the generator with an emergency pump driven by the pressure of the pressure gas cylinder in an emergency so as not to hinder the operation of the emergency generator.

It is preferable that an operation valve for operating the emergency operation valve is further added. The emergency operation valve receives a valve opening force based on the pressure of the pressure gas cylinder via the operation valve. The end of the drain valve is typically a number of sprinklers.

The water chamber is composed of a first water chamber for storing the first vibration damping water and a second water chamber for storing the second vibration damping water. In this case, the second damping water is used as drinking water. It is not preferable to store a large amount of daily-used drinking water at the same time.

BEST MODE FOR CARRYING OUT THE INVENTION Corresponding to the drawings, in an embodiment of a multifunctional elevated water tank according to the present invention, an air cylinder is provided together with a multifunctional elevated water tank. As shown in FIG. 1, the air cylinder 1 is connected to the multifunctional elevated water tank 3 via a main pipe 2. The air cylinder 1 is preferably provided as a high pressure air-tight container that does not necessarily require a compressor. The air cylinder 1 may cause a decrease in internal air pressure for many years.

Pressure switch 4 attached to the air cylinder 1.
Normally monitors the air pressure in the air cylinder 1. The pressure switch 4 converts a decrease in the air pressure in the air cylinder 1 below a specified pressure into a pressure drop monitoring signal 5, and a remote installed by a multi-function elevated water tank manager via various lines / nets 20. The pressure drop monitoring signal 5 is transmitted / reported to the monitoring electronic device 7 of the monitoring center 6 as pressure drop information. Upon receipt of the pressure drop monitoring signal 5, the supervisor in charge of the monitoring center 6 replaces the new air cylinder 1 with the old air cylinder 1. It is important to constantly monitor the air pressure of the air cylinder 1 and the open / closed states of the open / close valves arranged everywhere in preparation for an emergency.

The pressure control valve 8 is provided in the main pipe 2. The pressure control valve 8 mechanically (non-electrically) adjusts to the operating air pressure P in the multifunctional elevated water tank 3 which is the pressure on the downstream side.
In response, the operating air pressure P is maintained / maintained constant.
The instantaneous valve opening / closing operation of the pressure control valve 8 that maintains / maintains the operating air pressure P at a constant level is physically / mechanically automatic and non-electrical. Therefore, the pressure control valve 8 can surely perform the valve opening / closing operation regardless of the operation / non-operation of the electric system at the time of fire or earthquake.

The normality of such mechanical operation is regularly inspected by a supervisor in charge. The pressure control valve 8 is a known technique that operates with the downstream pressure as a mechanical feedback signal 9. When the pressure in the air layer 12 exceeds the specified pressure, the air in the air layer 12 can be discharged to the outside via the safety valve 13.

In the multi-function elevated water tank 3, the lower layer is a water tank or water layer 11 and the upper layer is an air tank or air layer 12 at two places. The same pressure in the two separated air layers 12 suppresses the movement of both sides S of the water layer 11 during an earthquake. The air layer 12 is pneumatically equivalent to a spring. The movement period (frequency) of the water layer 11 is determined by the equation of motion described by the pressure P, the volume of the air chamber, and the length of the water layer. The vibration of the water tank resonates in synchronization with the frequency of the building, and the reaction force of the vibrating water can suppress the vibration of the building structure.

The movement of water in the multifunctional elevated water tank 3 is formulated by a so-called U-tube vibration model. The parameters of the vibration system whose equation of motion is formulated are the volume of the air chamber, the length of the water tank, and the spring constant of the air in the air chamber above the water surface. The frequency that can be solved by the equation that regulates the external force at the time of an earthquake resonates with the frequency of the building structure, and the inertial force of the vibration acts on the building structure as a reaction force to attenuate the vibration. . Since the spring constant is described by the operating pressure P of the air chamber, which is one of the external forces appearing in the equation of motion, its frequency can be adjusted by adjusting the operating pressure P. Such operating pressure P is the pressure control valve 8
Can be easily adjusted by mechanical adjustment.
