Description

Seismic device with double stage structure {EARTHQUAKE-PROOF DEVICE HAVING DOUBLE STAGE STRUCTURE}

The present invention relates to an earthquake resistant device, and more particularly, to an earthquake resistant device having a double stage structure.

In general, when an earthquake occurs, seismic waves are generated. Among these seismic waves, the center wave, which is a solid wave, has a P wave and an S wave, and the propagation speed of the P wave is 7-8 km / s. Pass through all liquids and gases. On the other hand, the S wave is slower than the P wave and is a vibration wave arriving after the P wave. The speed is 2 to 4 km / s, and the transverse direction of the particle vibration of the medium is orthogonal to the traveling direction. Damage is greater than waves and only solids pass. Therefore, the S wave does not pass through the liquid, so if the building structure using the floating method using a fluid such as water can significantly reduce the damage caused by the high S wave.

Most seismic design techniques for building structures are made through the number of columns and slabs that resist axial and bending moments, increasing the number of rebars, expanding the cross section, using high-strength materials, and reinforcing structures using reinforcement frames. . The seismic design of this method does not solve the fundamental problem of enormous construction cost and long construction period.

In particular, the seismic design of the above method is merely a support for the deformation force of the axial force and the bending moment. Therefore, the building structure collapses in a moment if it cannot sustain the deformation force.

As an example of a seismic reinforcing device for seismic design of another building structure, summarizing the technical contents disclosed in Korean Patent Publication No. 0326972 (hereinafter referred to as “prior patent document”), as shown in FIG. 1, A lower pedestal 120 having a flange portion 112 and a concave groove 114 formed outward at a lower portion, a pedestal 120 having a dome-shaped concave groove 122 formed at a lower surface thereof, and a concave groove 122. It is composed of a steel ball 130 that is absorbed by the upper pedestal 120 to absorb vibration when the earthquake occurs, and a cylindrical elastic body 140 elastically supporting the upper pedestal 120. Therefore, the prior patent document can be summarized as a technique for absorbing and mitigating the horizontal movement of the pedestal 120 using the steel ball 130, and the vibration in the horizontal and vertical direction by the elastic body 140.

By the way, the vibration absorbing device of the ground structure proposed in the prior patent document has a coupling structure in which the horizontal displacement of the pedestal 120 occurs even when absorbing and relaxing the vibration transmitted in the horizontal direction by using the elastic force of the elastic body 140. . Therefore, a structure (for example, a pillar) supported by the pedestal 120 is interlocked together, thereby affecting the structure. In addition, the vibration absorbing device of the ground structure proposed in the prior patent document, when the vibration is transmitted simultaneously in the horizontal and vertical direction, the elastic body 140 is elastically supported in the horizontal direction against the vibration in the horizontal direction, at the same time in the vertical direction With respect to the vibration transmitted from the elastic body 140 is elastically supported in the vertical direction. However, in the state in which the elastic body 140 is compressing and relaxing in the horizontal direction at the same time, the compression and relaxation in the vertical direction cannot be effectively performed. Consequently, simultaneous elasticity support in the vertical and horizontal directions is difficult to be achieved. There is this.

That is, the vibration absorbing device of the ground structure presented in the prior patent document is difficult to effectively cope with the vibrations transmitted in the horizontal, as well as the structural problems as mentioned above for the vibrations simultaneously transmitted in the vertical and horizontal directions, As a result, the safety against earthquake resistance of the building structure cannot be guaranteed. In addition, it is possible to cope with the Richter scale of about 6.5 in accordance with the current legislation of the building, it is virtually impossible to respond to more earthquake, and there is a problem that the economic cost is enormous.

The present invention has been proposed to solve the above problems of the conventionally proposed methods, by configuring the stage portion that can block the vibration of the S wave with the horizontal moving member by the dual structure of the lower stage and the upper stage, It effectively absorbs and mitigates vibrations associated with seismic waves in the horizontal and vertical directions without increasing the number of columns and slabs, increasing the number of reinforcing bars, expanding cross sections, using high-strength materials, and reinforcing frames. It is an object of the present invention to provide an earthquake resistant device having a double stage structure in which the influence of the S wave having a high breaking force can be prevented at the time of application.

In addition, the present invention, even if the vibration is transmitted in the horizontal and vertical direction at the same time can effectively cope, and also absorb and mitigate the displacement of the column and ground caused by the vibration to further ensure the safety of the building structure, fluid It is possible to block the vibration of S-wave by using it, and it is possible to drastically improve the seismic capacity, and it is possible to use the factory made or fabricated building method method, which has a double stage structure that can greatly reduce the cost and shorten the air. Another object is to provide an earthquake resistant device.

In addition, the present invention, in the case of earthquake-resistant construction that is operating in accordance with the legal limiting device of the seismic building and the Richter scale 6.5 in accordance with laws and regulations, the construction cost according to the seismic design is conventionally increased by 35-40% It is another object to provide a seismic device with a double stage structure, which can be reduced, and the construction is quick and simple, so that the construction period can be shortened and the seismic strength can be increased up to 9.0 on the Richter scale. do.
