Earthquake-resistant reinforcing system

Introduction

The wire and nickel coating method had been developed by KangToe IDTech. Its pending technology can be applied in various structures.

Next year, we plan to develop an adhesive epoxy product which is a chemical reinforcing method that combines the cement and boring-hole in one. It has 30% more strength and better stability than the present earthquake-resistant method. It will replace expensive earthquake-resistant products being imported now.

Technical difference from other companies

Difference 1

Hydraulic damper / Earthquake-resistant reinforcing system (KangToe IDTech patent pending)

-It can improve existing system with damper only by adding a spring

-One unit is sufficient for a part that receives light load

-If a part receives heavy load, the number of dampers and springs can be changed. Therefore, customized design for different floors is possible

-Damaged springs can be individually replaced. cost saving!!

Difference 2

Spring

Earthquake control system: absorb vibration energy ? restrict displacement and reduce loading

-Limitation in reducing the acceleration response (damper limitation)

-Limitation in reducing earthquake force

(it should have both period-shift function and damping function simultaneously)

Customized Damper

Function (performance)

1. It is possible to make customized dampers dependent on the displacement between floors of a building

2. The spring can stand the vertical load and torsion load

3. Damper with higher degree of freedom is possible

4. The fatigue failure can be complemented

5. Various types of damper can be made by varying the shape of coil type carbon damper (number of return, linear diameter, coil diameter, pitch and others)

Cost

1. Spring or damper can be individually replaced when it is necessary to replace after an earthquake

2. Relatively inexpensive because it uses multi-damper with smaller capacity

3. Relatively inexpensive than existing dampers (e.g. SS400 steel made) because it uses spring

4. Can reduce construction cost when reinforcing earthquake control

5. Use less number of dampers

Earthquake-resistant reinforcing system

Earthquake-resistant structure

* Increase structure strength

* Absorb vibration energy from the structure itself by considering the ductility

* Prevents the fall down of whole building though there would be partial damage

Earthquake control structure

* Absorb energy through special device

* Improve and secure habitability, functionality, stability and cost effective

* The earthquake control device will yield earlier than the main structure members of the building ? absorb and diffuse the earthquake energy applied on the structure
