Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for protecting cultural properties and the like from an earthquake, and more specifically to an earthquake disaster prevention method suitable for protecting cultural properties and the like from an earthquake disaster.

[0002]

2. Description of the Related Art In the prior art, the mainstream method is to damp vibrations when an earthquake occurs, and the display stand or the entire building has been implemented. In addition, instead of damping the vibration, the earthquake detection device detects an earthquake when an earthquake occurs, the drive device is activated by the signal, the pair of opening and closing plates open, and the inside of the protective bag installed under the opening and closing plates There is a method of storing a cultural property (Japanese Patent Application No. 2000-047290).

[0003]

Although the conventional method is not sufficient for the technology for dealing with the first earthquake, it can be dealt with as it is. However, damage to cultural properties is unavoidable due to concrete fragments falling from the ceiling due to partial collapse of the exhibition hall due to the earthquake. Even with the protection method that had the most safety measures (Japanese Patent Application No. 2000-047290), even if a pair of opening and closing plates opened at the initial earthquake and cultural properties were stored in the protective bag, the upper side of the protective bag It is necessary to take measures to block the open opening. In addition, when closing the opening, if cultural assets are still stored in the protective bag while valuable cultural assets are still stored in the protective bag, the cultural assets may be damaged. After being stored in a protective bag, the opening is closed, and there is a time difference.

[0004]

[Purpose] The present invention aims to solve the problems (Patent application 200 filed by the present inventor)
0-047290), the first earthquake,
A pair of opening and closing plates open, and the cultural assets stored in the protective bag are destroyed by collapse of the ceiling of the exhibition hall, etc., and falling objects such as concrete debris enter through the opening on the upper side of the protective bag. The purpose is to prevent such damage.

[0005]

[Means for Solving the Problems] A method for reliably protecting cultural properties and the like from an earthquake disaster according to the present invention is, as mentioned in the problem, by a concrete fragment falling from the ceiling due to a partial collapse of a building due to an earthquake. , To prevent damage to cultural properties.

It is characterized in that after the cultural property is stored in the protective bag due to the occurrence of an earthquake, the upper opening of the protective bag is closed.

There are various closing methods such as a method of returning the pair of opening / closing plates to their original positions, and a method of closing with a shutter. The present invention employs an inexpensive method that surely closes the opening.

According to the method, when an earthquake occurs, the earthquake detection device detects the earthquake, the drive device is activated by the signal, the pair of opening and closing plates are opened, and the cultural property is stored in the protective bag. However, during the series of operations, when the opening and closing plate opened 45 degrees or more,
The door movement start switch that closes the opening is turned on, the rotary solenoid operates, the door movement stopper pin operates, and the standing door moves due to the weight of the door, and the opening is reliably closed. In addition, there is a time lag between the opening of the pair of opening / closing plates and the start of movement of the door that closes the opening.

The necessity of this time difference is that when the work of opening the pair of opening / closing plates and the work of closing the door to close the opening are started at the same time, before the cultural property is stored in the protective bag. ,
It is necessary for safety, as the movement of the door may damage cultural properties.

After the earthquake, cultural properties are stored in the protective bag, and after the upper opening of the protective bag is closed, a large aftershock continues, and the falling objects from the ceiling fall on the display stand. However, the cultural property stored in the protective bag is surely protected.
