Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic control structure and a construction method thereof for protecting an object, such as a house or a communication parabolic antenna, which should not be tilted or displaced on the spot from an earthquake.

[0002]

2. Description of the Related Art Conventional houses and other structures are constructed by burying the base of the foundation in the ground or driving concrete piles to form a strong foundation and fixing the house and the structure directly to the foundation. There is.

[0003]

In conventional houses and other structures, when the ground shakes due to an earthquake, the foundation fixed to the ground shakes, and the houses and structures fixed to the foundation also shake. In other words, no matter how sturdy a house or structure is, it will shake if there is an earthquake, and if it shakes violently, furniture will fall, walls will fall, roof tiles will break,
In the worst case, there was a problem that houses and structures themselves would collapse.

The conventional seismic isolation structure has a problem in that the seismic isolation structure only has the effect of softening the seismic intensity, and the more severe the seismic intensity, the stronger the seismic intensity of the seismic isolation structure.

Another problem is that the conventional seismic isolation structure is not very effective for pitching.

An object of the present invention is to solve the above problems and to provide a wooden house and a low-rise RC house which do not shake even when an earthquake occurs.

[0007]

In order to achieve the above object, in the vibration control structure of the present invention, the house and the structure are not fixed to the ground but the coil spring, the pressure resistant vinyl water cushion, the hydraulic active suspension system. It is designed to be supported by.

Taking the case of a house as an example, first of all, the above-mentioned three kinds of installation places have hydraulic active suspension systems installed at respective corners, and the coil springs and the pressure-resistant vinyl water cushions are arranged on the whole according to the partial weight of the house. Good to do.

And to control the most important shaking,
The hydraulic active suspension system has a hydraulic system that constantly generates power, and sensors located at various locations detect sway movements, adjust the hydraulic pressure, and absorb the energy of sway due to earthquakes.

When excessive vertical vibration is applied for a moment, the energy of the vertical vibration is absorbed by moving the water of the pressure-resistant vinyl water cushion.

[0011]

[Function] In the seismic control structure house installed as described above, when rolling, the coil spring that mainly supports the main body of the wooden house and the grounding portion of the pressure-resistant vinyl water cushion move in the same way as an earthquake. The shock absorbers, coil slings, and pressure-resistant vinyl water cushions, which are compressed and filled in the coil springs, act to absorb the rolling motion and alleviate the energy transmitted to the house.

In the case of pitching, first, the energy of pitching at a large moment is changed to the moving energy of water in the pressure-resistant vinyl water cushion and absorbed.

Then, the small sway after that acts to absorb by the coil sling and the hydraulic active suspension system.

However, these three types of devices do not operate in response to earthquake tremors in sequence or separately, but operate to share the tremor energy in accordance with their capabilities and to assist and absorb each other. To do.

[0015]

EXAMPLE An example of the method of construction will be described by taking a wooden house as an example. In FIG. 1, the foundation portion 1 is made by pile driving to solidify the ground, and then the reinforcing bars are sufficiently inserted and concrete is poured. At that time, the metal fittings for the coil sling, the hydraulic active suspension system, and the piping for water and sewerage, gas, electricity, etc. should be buried.

Next, based on the drawing of the wooden house, considering the weight distribution at the time of completion of the house, the coil sling 5 is installed and fixed so that the house is housed horizontally.

Then, the steel material for fixing the base 4 of the wooden house is arranged in the same manner as the base 4 of the wooden house, and the steel material is received by H steel to form the base portion 2 on which the main body of the wooden house is placed.

The base part 2 is installed and fixed on the coil spring 5, and the hydraulic active suspension system 3 is also installed and fixed on the base part 2, and the hydraulic system 12 is connected and fixed to the base part 1.

After fixing the base 4 of the wooden house to the base portion 2, the conventional construction method is the same. Note that the hydraulic active suspension system 3 will be used even during the construction period.
Recommends construction work in working condition.

Finally, after the construction work is completed, the pressure-resistant vinyl water cushion 6 is completely evacuated from the air bleeding valve 18 while considering the weight balance, and then the pressure proof belt 19 is used to pressurize the cushion. Then, the space between the base portion 1 and the base portion 2 is closed from above and below with a thick rubber 13 for shielding.

In the embodiment shown in FIG. 2, the coil spring main body 10 is compression-filled with a shock absorbing material 9 and is attached to the base portion 2 to prevent rolling, and the rolling prevention rod 8 to be embedded in the base portion 1 is provided. Is attached.

In the embodiment shown in FIG. 3, sensors 14 are arranged at each corner and the center of the base portion 2, and the hydraulic system 12 is installed between the base portion and the foundation portion.

In the embodiment shown in FIG. 4, the outlet 20 of the pressure-resistant vinyl 15 is made of thin pressure-resistant vinyl so that it will be broken and the water will flow out when a certain pressure is applied. Collect the flowing water with vinyl hose 16 at one place. It is covered with a rubber coating 17 for protecting and supporting the pressure-resistant vinyl after pressing.

[0024]

Since the present invention is configured as described above, it has the following effects.

By not supporting the main body of the wooden house directly with the foundation, but supporting it with a coil spring and a pressure resistant vinyl water cushion, it is possible to alleviate the shaking of the main body of the house without directly transmitting the rolling of the earthquake to the main body of the house.

Then, by supporting with a pressure-resistant vinyl water cushion and a coil spring, the vertical vibration of the earthquake is converted into moving energy of water and absorbed, and the energy that cannot be absorbed is absorbed by the coil spring.
It can reduce vertical vibration.

Further, the energy of vertical and horizontal vibrations that cannot be absorbed by the coil spring and the pressure-resistant vinyl water cushion can be absorbed by installing a hydraulic active suspension system.

Further, by collecting the flowing water used in the pressure-resistant vinyl water cushion at one place, it can be used as fire-prevention water together with the water remaining in the cushion.

The fact that the houses will not collapse due to the shaking caused by the earthquake was reported to be the cause of the damage caused by the Great Hanshin Earthquake on January 17, 1995 due to the weight of the tile roof and the conventional frame construction method. As a result, roof tiles are separated and traditional frame construction methods are separated, and traditional techniques, industries, and construction methods tend to be neglected, but it is possible to prevent such things and help protect and nurture traditional techniques, industries, and construction methods. .

Furthermore, even if an earthquake occurs, the damage can be minimized by using the present invention.
It can also contribute economically, socially and welfare.
