Description
The present invention relates to an isolation structure for horizontal and vertical extension remodeling, and more particularly, to an isolation structure applicable to an existing building having a seismic design.
In order to resist the seismic force, a separate device such as 'earthquake' which is designed to make the structure made of pillars or reinforcing materials as strong as possible or a huge weight (pendulum type vibration damper) , 'Isolation' is a technique to minimize the amount of seismic force transferred directly to the building by separating the building from the foundation.
Specifically, seismic isolation is a technique of separating a building from a ground by inserting a special damping structure between the building and the foundation. A mechanism such as a seismic isolation device (see FIG. 4) This is a technique that can effectively improve the seismic behavior of the superstructure of the building by reducing the seismic effect on the building by making the period longer.
These seismic isolation technologies have been recognized for their excellence as technologies that have been demonstrated and commercialized mainly in countries that have experienced earthquakes such as Japan, USA, New Zealand and China.
In addition, it is a very practical method to effectively improve the seismic performance of existing structures as well as the expansion / contraction structures under conditions that do not impair the function or aesthetics of the structure itself.
Internationally, there is a growing interest in seismic rescue systems, and the Korean Building Construction Standard (KBC) is also expected to introduce new regulations on the current seismic structure, reflecting the situation. However, specific design standards and guidelines are insufficient.
A related prior art will be described.
Japanese Patent Application Laid-Open No. 2001-227176 provides a method of reducing an earthquake force transmitted to an existing building by providing an insulation layer at the time of expansion. However, there is no consideration of a technology for expanding the space for enlargement in the remodeling by using the seismic layer only because it is only a consideration of providing the seismic layer in the enlargement process.
Japanese Patent Registration No. 4092624 relates to a seismic structure of a building, in which an intermediate seam layer is formed between an upper structure and a lower structure, and a seismic structure in which an seismic device is disposed in the middle seam is provided. However, this technology also has a low remodeling efficiency due to the lack of discussion on horizontal expansion.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems.
Specifically, a seismic layer that is wider than that of an existing building having a seismic design (for example, a building to which seismic design was built since 1988) is provided, so that it is possible to perform vertical expansion remodeling as well as horizontal expansion remodeling. And to provide a seismic isolation system that can be secured.
Here, we propose an isolation structure system that can be remodeled because it can be applied to not only buildings that are earthquake-resistant, but also those that are not.
Also, in case of existing buildings, it is proposed to reduce the floor shear force at the upper part and to reinforce the columns at the horizontally extended part to minimize the seismic reinforcement of existing buildings. In addition, a seismic system capable of enlarging a wall-mounted structure, which is difficult to extend with conventional isolation systems, is proposed.
According to an aspect of the present invention,

The present invention can vertically enlarge and remodel the upper part of the existing building including the seismic layer which is wider than the uppermost horizontal width of the existing building, and also can horizontally enlarge and remodel the existing building including the horizontally enlarged side part pillars.
In addition, since the seismic isolation layer is formed as a separate layer, the maintenance and repair are easy, and the load transfer to the existing building is minimized in the vertical enlargement space remodeled vertically (see FIG. 1).
In addition, due to the seismic layer of the seismic isolation system according to the present invention, the vibration period of the remodeling building is increased, and the seismic load transmission is reduced.
In addition, due to the horizontal enlargement column for horizontal expansion remodeling, the amount of structural reinforcement such as walls and foundation is minimized, which is economical.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Here, the constituent elements of the present invention can be used integrally or separately from each other as needed. In addition, some components may be omitted depending on the usage form. Various modifications can be made in the form and the number of elements of the present invention.
A preferred embodiment of a plane structure system capable of vertical and horizontal enlargement according to the present invention will be described with reference to the accompanying drawings. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, the definitions of these terms should be described based on the contents throughout this specification.
It should be understood that other types of vertical and horizontal retrofitted seismic systems, including all of the elements in one embodiment or having other features in this specification, may be readily derived.

Here, the "wall structure" is one of the structural methods of the building, which is composed of foundation, floor and wall, and the load of the floor slab is lowered through the wall at the lower end and transferred to the ground via the foundation plate. However, when the isolation structure system according to the present invention is applied, planar variability is ensured.

Here, the horizontal extension distance d is preferably 50 cm to 70 cm.
These figures have two meanings.
First, when the horizontal expansion distance (d) is less than 50 cm, the economic effect due to the horizontal expansion is smaller than the remodeling cost, and when the horizontal expansion distance (d) exceeds 70 cm, the isolation performance itself decreases.
Second, there is an analysis that it is desirable to increase the expansion area by 30% to 40% of the existing building area because it may cause various problems including the structural safety problem when the expansion area is wider than the existing building. Therefore, It is preferable that the horizontal extension distance d is set to 50 cm to 70 cm.

Examples of laminated rubber types include a lead-in type, a high-attenuation type, and a low-attenuation type. Examples of the non-laminated rubber types include a ball type, a roller type, and a line type.
For example, as shown in Fig. 5, the resilient seals may be alternately laminated with a thin rubber and a reinforcing steel plate. Alternatively, it may be a lead-free bearing that provides a large damping force by the hysteretic behavior of the lead as well as providing initial stiffness for small lateral forces such as wind loads by inserting lead in the center.
