Description

FRAME STRUCTURE AND PANEL STRUCTURE AND FRAME CONNECTING STRUCTURE}

The present invention relates to a frame structure that absorbs vibration, a panel structure including the frame structure, and a frame connecting structure.

It should be noted that the content described in this section merely provides background information on the present invention and does not constitute a prior art.

Curtain wall and building exterior material is composed of glass or exterior member, lower frame and various parts connecting them.

The seismic performance of the exterior material may be realized by the connection performance between the exterior member and the lower frame, the lower frame and the structure, and the seismic structural performance of the lower frame itself.

The connection between the outer member and the lower frame and the lower frame and the structure is connected by parts called fasteners and anchors, and the seismic performance is improved by lateral or rotational movement of the outer material through these parts in case of an earthquake. Implement.

In addition, consideration should be given to the seismic structural performance of the curtain wall frame or the lower frame itself. Even if the fasteners and anchors, which are the connecting parts, function properly, the curtain wall frame or the lower frame does not withstand displacement, causing excessive deformation or joints. If breakage occurs, there is a problem that can not implement seismic safety.

In particular, in the case of a high-weight glass member or stone, the possibility of dropping the exterior member due to its own weight increases, so the seismic structural performance of the curtain wall frame or the lower frame is also very important.

In other words, the curtain wall / base material frame should have the resistance against earthquake, wind pressure, and heavy weight of the exterior weight, and should be able to reduce the transmission of vibration to the exterior member when an earthquake occurs.

In addition, such a curtain wall frame or a lower frame should be able to withstand wind pressure and deformation of its own weight direction, and should be excellent in heat insulation performance, resistance to dew condensation, and fire resistance by delaying thermal bridges.

Therefore, there is an urgent need to develop a frame structure that can solve these problems.
