Description

Frame structure, panel structure, frame connection structure {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 connection structure.

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

Curtain walls and architectural exterior materials are composed of a glass member or exterior member, a base frame, and various parts connecting them.

The seismic performance of the exterior material can be realized by the connection performance between the exterior member and the base frame, the base frame and the structure, and the seismic structure performance of the base frame itself.

The connection between the outer member and the lower frame and the lower frame and the structure is connected with parts called fasteners and anchors. In the event of an earthquake, these parts are configured to enable lateral or rotational movement of the exterior material, thereby improving seismic performance. I am implementing it.

In addition, it is necessary to consider the seismic structure performance of the curtain wall frame or the base frame itself. Even if the fasteners and anchors, which are the connecting parts, function properly, the curtain wall frame or the base frame cannot withstand displacement, resulting in excessive deformation or joints. If the damage occurs, there is a problem that the seismic safety cannot be implemented.

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

That is, the curtain wall/substrate frame must have resistance to earthquakes, wind pressure, and the self-weight of the heavy exterior material, and must be able to reduce the transmission of vibration to the exterior member when an earthquake occurs.

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

Therefore, there is an urgent need to develop a frame structure capable of solving these conventional problems.
