Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone curtain wall using a panel in which a stone as an outer wall material is integrated with a frame.

[0002]

2. Description of the Related Art A stone curtain wall using a stone material as an outer wall material is a method of sticking a stone material to a concrete outer wall with a metal or mortar, and a curtain wall unit in a frame. It is roughly divided into a method of mounting it on a frame and a method of supporting it on the frame, but the former method only gives a primary seal at the joint between the adjacent stone materials, and a secondary seal does not have an outer wall on the indoor side of the stone material. Since it is necessary, it can be applied only to reinforced concrete buildings, whereas the latter method does not care about the structural type of the building because a secondary seal is secured between the frames because the frame is integrated with the stone material. In addition to
At the site, it has the advantage of good workability because it is supported only by connecting the frame to the frame. At present, the latter method is becoming the mainstream of stone curtain walls.

The stone panel in which the stone is integrated with the frame is supported by the skeleton by connecting the fastener fixed to the back surface to the fastener fixed to the outer wall, the slab, or the beam, but is connected to the building skeleton. While the position is uniquely determined by the embedded position of the fastener on the body side,
Since the embedding position differs from building to building depending on the type of structure and the design of each building, it is conventionally necessary to change the mounting position of the fasteners on the stone panels for each building, making it impossible to unify the panel manufacturing and to construct the frame. Is independent of panel manufacturing, it is indispensable to position the panel after it is hung.

The present invention has been made in view of the actual situation of a stone curtain wall using a panel in which a stone material is integrated with a frame, and an object thereof is to propose a stone curtain wall which does not select the structural form of a building or the like.

[0005]

According to the present invention, a slab is supported by a slab, and a stone panel is connected to the slab so that the building is supported by the slab, thereby supporting the stone panel at a supporting position regardless of the form or design of the building. And the positioning work is simplified to improve the workability of on-site installation.

The stone panel is unitized by attaching stones to a frame assembled in a square shape from an upper frame, a lower frame, and a vertical frame, and is factory-manufactured together with the stone panel to form a cubic find surface supported by a slab. It is joined to a fixed bracket and supported vertically.

Since the stone panel is connected to the cuboid, the support position of the stone panel is fixed without being controlled by the structure of the building or the embedded position of the fastener, and the production is unified. At the same time, since the stone panels are connected to the cuboid where the connection position is determined in advance, the work of positioning the stone panels on the site is simplified. Installation accuracy is secured.

[0008] Further, by laying a sealing material around the outer periphery of the frame of the stone panel and between the frame and the stone material, it is possible to mount them between the stone panels which are adjacent to each other in the height direction and the lateral direction only by mounting on the upright. Secondary seal is applied.
