Description

Buoyancy construction methods for earthquake-proof for earthquake-

The present invention relates to a floating method for earthquake-resistant design, and in particular, in the construction of a building structure for earthquake-resistant design, a plurality of vibration isolation devices are disposed between the building structure and the ground to prevent the building structure from directly contacting the ground, The present invention relates to a method for positively blocking S waves that can not pass through a fluid among seismic waves having strong destructive power by constructing an architectural structure by using fluid buoyancy.

An earthquake is a phenomenon in which energy generated by the action of a fault is transmitted to a wave through a stratum, and the wave transmitted thereby has an actual wave and a surface wave. The actual wave can be divided into P wave and S wave again. The P wave is the wave that arrives at first, and it is called denomination. The P wave is physically a squeak wave, a compression wave, and is transmitted by oscillating in parallel to the transmission direction. The medium through which the P wave can pass is all through the solid, liquid and gas. The S wave, which is also called the transverse wave, oscillates perpendicularly to the transmission direction and is transmitted. Shear waves, torsional waves, and so on, are more damaging than P waves and can not penetrate liquids.

The collapse or damage of an architectural structure is mainly due to lateral loads. Lateral loads acting on building structures are wind and seismic loads. Wind load is more influenced by the external shape than the structural property of the building structure, but the earthquake load is influenced by the inertia force and therefore it is influenced by the dynamic characteristics of the structure. The idea of seismic isolation or seismic design is based on blocking the transmission of this lateral load. The seismic design currently used mainly consists of laminated rubber bearings, tuned mass damper, tuned liquid damper liquid damper).

The dynamic properties of the rubbery layer structure as the isolator are susceptible to deterioration due to changes in the microstructure due to thermal aging of the rubber. Because it is very vulnerable to heat, it requires steady management and can cause fatal damage due to unexpected earthquakes.

On the other hand, tuned mass attenuators or tuned liquid attenuators are often installed to control the unidirectional behavior of building structures. In some cases, several control devices or special type tuned mass attenuators Tuned liquid attenuators may also be used. When controlling by using two or more control devices, the mass ratio of the unidirectional control device is required to be twice or more, and the load of the building structure is greatly increased accordingly.

As mentioned above, the damage of seismic waves due to earthquakes is larger than that of P waves, and seismic design for earthquakes has the basic idea to block the lateral load received by the building structure. The conventional rubber layered structure for lateral load blocking has a disadvantage that it is vulnerable to heat. In the case of tuned mass attenuator and tuned liquid attenuator, only one directional control is possible.

Therefore, in order to prevent damage caused by such an earthquake, a more effective seismic design is desperately required.

The structure and function of the floating method for seismic design according to the present invention will be described with reference to FIGS. 1 to 6 as follows.

A trenching step for the building of the building structure 100 is carried out.

In this case, the size of the tower is designed to be larger than the size of the building structure (100) in order to prevent the building structure (100) from directly touching the earth for seismic design.

An earth retaining beam 110 is installed on the side walls of the wave exciter to prevent the side walls from collapsing.

Here, the surface of the earth retaining beam 110 is waterproofed and installed in advance.

A first waterproofing film 120 is provided on the side wall and a bottom surface of the waveguide and a net 130 is laid on the first waterproofing film 120. The second waterproofing film 140 So as to prevent water, seawater, brine, and the like, which is a fluid for holding the buoyancy, from flowing out.

Here, the material of the first waterproof film 120 and the second waterproof film 140 may be selected from any one of polyester, polypropylene, polyvinyl chloride, polyethyrene, poly (ethylene terephthalate), and nylon .

In addition, a plurality of vibration isolation devices 160 are installed at predetermined intervals between the honeycomb-shaped integral structure of the building structure 100 to be built and the foundation header of the tower.

Here, the plurality of vibration isolation devices 160 directly support the building structure 100.

In other words, the building structure 100 is constructed on the vibration suppression device 160 and eliminates the portion directly contacting with the earth, thereby reducing the damage caused by the seismic waves.

An integral reinforcing structure in the form of a honeycomb structure is formed on the plurality of vibration isolation devices 160 and an architectural structure 100 is formed on the structure. (310) is provided to reduce the shaking due to external force.

As there is no direct contact with the earth, wind shaking due to wind load may occur. Accordingly, the stability of the building structure 100 can be improved by the plurality of tensioners 310 catching the shaking due to the external force.

At this time, the tensioner 310 can be installed between the lower part of the building structure and the installed earth moving bar 110.

The tensioner 310 should be appropriately disposed in accordance with the shape of the building structure 100 or the surrounding environment so that the building guide shaft is not shaken by an external force, wherein the tensioner 310 includes a radial or lattice arrangement .

Here, it is possible to further include a step of installing a plurality of nylon ropes or a plurality of wire ropes 300 connecting the upper and lower portions of the building structure.

The integrated structure constructed to enhance the role of the heat reservoir and the structural strength at the lowermost part of the building structure 100 includes a honeycomb structure 400, a pyramid truss structure, , A radial grid structure (420), or a square grid structure (410).

A flexible passway 170 is provided between the constructed building structure 100 and the ground.

Here, the moving passage 170 includes one that can flexibly cope with up, down, left, and right vibrations.

A hinge joint, a sleeve joint, and a knuckle joint may be formed at a connection portion between the moving path 170 and the earth and moving pathway 170 and the building structure 100, And the like.

The step of installing the plurality of vibration isolation devices 160 includes the step of installing the reinforcing pile 700 on the bottom surface and installing the pedestal of the hardened vibration isolation device 160 on the reinforcing pile 700.

When the ground is loose, the vibration suppression device 160 is shaken or is in an unstable state, so that the reinforcing pile 700 is supported so that the foundation is firmly supported.

7 is a view showing the filling of incompressible fluid 150 such as water in a space between a building structure and a space separated from an architectural structure 100 using a floating method for seismic design according to an embodiment of the present invention .

Filling the fluid 150 with the fluid 150 is to utilize the buoyant force of the fluid 150 and to block the seismic waves to reduce damage.

Here, the fluid 150 to be filled comprises selecting either water, seawater or brine.

The buoyancy acts in the opposite direction to the gravity depending on the volume of the object immersed in the fluid 150, and its magnitude is given by Equation 1 below.

Here, p represents the density of the fluid 150 in which the object is immersed, and V represents the volume of the portion where the object is immersed.

That is, the larger the density of the fluid 150, the larger the volume of the portion where the object is immersed, the larger the buoyancy becomes.

The inclusion of the highly dense fluid 150 reduces the size and number of the installed vibration damping apparatus 160 because a force for supporting the weight of the building structure 100 is generated due to buoyancy of the fluid 150.

Here, the building structure supports 70 to 90% of the load of the building structure 100 by buoyancy, and the load of the remaining 10 to 30% is the minimum (minimum value) provided to prevent the unreasonable state And may include installing the device for the purpose of maintaining the position of the building structure 100 through the plurality of vibration isolation devices 160.

8 is a view showing the application of the resistance blade structure 200 in the building structure 100 using the floating method for seismic design according to an embodiment of the present invention. And installing a plurality of resistance vane structures (200) to attenuate the resistance vane structure (200).

Since the building structure 100 is not fixed to a hard floor, the building structure 100 may be shaken by an external force such as wind.

Accordingly, it is possible to install a plurality of resistance blade structures 200 in the lower portion of the building structure 100, which is submerged in the fluid 150, in addition to the tensioner 310 described above in order to damp the shaking due to external force .

The plurality of resistance blade structures 200 serve to increase the frictional force or the resistance force with respect to the fluid 150, so that the moment due to the external force acting on the building structure 100 can be attenuated. At this time, the shape and size of the resistance blade structure 200 may be changed according to the properties of the fluid 150. As the viscosity of the fluid 150 is larger, the shape and size of the resistance blade structure 200 may be smaller .

9 is a view showing an application of an isolated work space 600 of a vibration isolation device in a building structure 100 using a floating method for vibration isolation design according to an embodiment of the present invention, And applying a separate confined space to the fluid 150 so that it does not directly contact the fluid 150.

The plurality of vibration damping devices 160 are operated in a state of being immersed in the fluid 150 so that the pressure acting depending on the type of the fluid 150 and the depth of the working fluid 150 is different, It is possible to make a separate vibration deadening device work space 600 so as not to directly contact the fluid 150 because there is a possibility of corrosion or deterioration of the vibration damping device 160. Maintenance and repair of the vibration isolation device 160 can be facilitated through the separate vibration isolation device work space 600.

In addition, since the separate vibration deadening device work space 600 is expected to be deformed due to the pressure of the external fluid 150, the automatic pressure adjusting device includes the equipotential chamber provided together.

Since the magnitude of the pressure applied to the vibration isolation device working space 600 is proportional to the density and depth of the fluid 150, the strength design of the vibration isolation device working space 600 is performed in consideration of this.

Here, the dust removing device 160 is automatically filled with an air pressure of equal pressure.

However, when it is necessary to fill the vibration damper 160 with the gas pressure, the pressure of the gas is supplied to the vibration damper 160 in the step of filling the fluid 150 It is preferable to fill.
