Description

Junction Structure of Installation Frame for Seismic Control Damper And It's Junction Method}

The present invention relates to a joining structure and a joining method of the frame, and more particularly to a joining structure and joining method of the vibration damper installation frame using an anchor bolt, a fixing agent and a filler.

Recently, due to a series of large earthquakes both at home and abroad, awareness of the earthquake's damage and the need for seismic design are spreading, and interest in the method of reinforcing earthquake reinforcement is increasing.

If the design of the building to be resistant to seismic forces is a general seismic design, seismic control is a method of minimizing damage to the building by efficiently dissipating the input energy caused by the earthquake using various damping devices. . Buildings designed to meet earthquake-resistant design standards through the 1994 Northridge earthquake and the 1995 Kobe earthquake could not avoid structural damage due to the earthquake and could threaten human safety. There is a growing interest in dust removal technology that can be safely preserved. It is known that more than one type of vibration suppression system is being designed in about 70% of middle and high-rise buildings over 60m in height. The representative vibration damper is a damper. Conventional damper technology in Korea has seen the damping effect using only one damper, such as steel damper, friction damper, oil damper, viscoelastic damper.

In installing the damping damper on the existing building wall, when connecting the damper frame and the contact area of the building wall, the anchor is inserted into the wall and fixed by inserting reinforcing bar and welding the reinforcing bar and frame. After attaching the plate to the wall and welding the frame and plate in the field, it takes a lot of time and manpower to work and in this case, it is affected by the outdoor environment due to the field welding and is relatively relatively compared to the factory welding. It is difficult to achieve the integration between the existing wall and the damper frame due to the deterioration of the quality and the low joining force, and due to the nature of the work, a large amount of time is required and the workability is deteriorated due to the welding work in a narrow space.

In addition, when the damper frame to be connected to the existing wall is connected to the existing wall, the bonding force is easily weakened by the influence of the outside temperature and humidity, and the damper frame to be connected is separated from the wall, and thus the purpose of the damper frame cannot be continuously maintained for a long time. . And, when connecting the existing wall and the frame using only the anchor, the frame must be fixed to the existing wall by the force of the anchor bolt alone, so the pressure applied to the anchor bolt is relatively large, increasing the number of anchor bolts to be used and the weight of the frame. If excessive, the anchor bolt is deformed there is a problem that can not continue the connection effect.
