In addition, the water tank is provided with a reinforcement means configured by combining a round rod (Tie rod) and a turnbuckle (Turn Buckle) in the fresh water space so as to prevent the so-called fullness phenomenon due to the water pressure of the water stored in the fresh water space.

However, the reinforcing means, for example, causes an individual movement of each part of the water tank when an earthquake occurs due to an earthquake, thereby increasing the risk of damage. And over time, corrosion in the fresh water space may cause water pollution, etc., and may cause inconvenience during cleaning of the fresh water space, and also have difficulty in maintenance.

In order to solve this, the internal unreinforced water tank according to the prior art (Patent Document 1) is constructed by installing a breakwater member instead of a turnbuckle and a joist (round bar) in a fresh water space.

That is, the sloshing of the water tank is prevented through the breakwater member, and the structure of the water tank is not damaged when an earthquake occurs. However, the internal non-reinforced water tank according to the prior art also has a reinforcing means called a breakwater member installed in a fresh water space, which may cause another problem.

Therefore, there is a need to develop a water tank capable of seismic design only by improving the structure without using any reinforcement means consisting of a breakwater member or a combination of a round bar and a turnbuckle according to the prior art.
