Description

  The present invention relates to a curtain wall that forms an outer wall surface of a building.

  As shown in FIG. 7, the curtain wall forming the outer wall surface of the building intersects a vertical beam 1 extending vertically and an invisible line 2 extending horizontally in the horizontal direction. It is set as the structure which incorporated the panel members 3, such as a glass plate and a decorative board, in the frame enclosed by.

  FIG. 8 and FIG. 9 show typical examples of curtain walls using wooden materials as frame members such as vertical 1 and seamless 2, respectively, along the outdoor end faces of vertical 1 and seamless 2. A wooden support member 8A. 8B, and wooden cover members 4A and 4B covering the vertical 1 and the invisible 2 respectively on the end surfaces of the supporting members 8A and 8B are provided with the wooden screws 41 with the vertical 1 and the invisible 2 through the supporting members 8A and 8B. The outer periphery of the panel member (glass plate in the illustrated example) 3 is interposed between the vertical member 1 and the cover member 4A, and between the mesh 2 and the cover member 4B via the sealing member 33 and the backup member 32. It is structured to be sandwiched and fixed.

  However, in this structure, the wooden cover members 4A and 4B are exposed to rain water or the like, so that the water is covered with the wooden cover members 4A. From 4B to the wooden support members 8A and 8B, the corrosion occurs with time, and there is a problem in durability.

  Therefore, the wooden cover member 4A. Although it is conceivable to use a metal such as aluminum instead of 4B, there is a possibility that the cover members 4A, 4B and the support members 8A, 8B may be damaged due to thermal expansion / contraction difference with the wooden support members 8A, 8B. .

  Therefore, it is made of a wooden material that is in harmony with indoor interior parts and furniture, is not apt to cause condensation in winter, and is made of a metal material that does not corrode as a member exposed to the outside air. A curtain wall structure has been proposed that absorbs thermal expansion and contraction between metal materials.

  For example, in the structure described in Patent Document 1 below, a metal base material in which slits or elongated holes extending in the longitudinal direction are respectively fixed to wooden end faces and endless outdoor end faces, and the slits Or, the head of the metal bolt member can be moved to the elongated hole, and the metal fitting is connected to the bolt member and the metal outer pressing edge member (cover plate) is connected to the metal fixture via a heat insulating material. The panel member is sandwiched between the cover member and the inner pressing edge member attached to the metal fixture so as to face the cover member.
