Description

  The present invention relates to a curtain wall structure that directly supports a panel such as a sheet glass in an outer wall portion of a building or the like. Specifically, the frame wall-like panel support member is not provided, and the four corners of the panel are directly supported. Thus, the present invention relates to a panel support structure in a curtain wall in which an outer wall surface is configured only by a panel in appearance.

  2. Description of the Related Art Conventionally, there is a structure in which a curtain wall structure that forms a wall surface of a building or the like does not have an eyelessness in order to produce an open feeling, and supports glass only by a vertical.

  Specifically, as shown in FIG. 13, this curtain wall structure uses a vertical 50 having glass fitting grooves M, M on both the left and right sides, and the vertical 50 is horizontally arranged at a predetermined interval in a casing or the like. In addition to fixing, the glass receiving members 51 and 51 are fixed at predetermined positions in the longitudinal direction of the vertical 50 and the glass receiving members 51 and 51 support the glass by supporting the end portions of the glass G and G. Is. Seals are filled in the joints between the adjacent glasses in the vertical direction so as to ensure airtightness.

  In the case of the curtain wall structure, it is natural that the joint width between the adjacent glasses in the upper and lower sides should be as small as possible. However, if each glass rotates in the same direction due to interlayer displacement during an earthquake, Since there is a possibility that the upper side corner portion may come into contact with the glass receiving member 51 and be damaged, the joint width has to be increased to some extent. Further, since the interlayer displacement is proportionally increased as the glass width dimension is increased, there is a problem that the joint seal impairs the feeling of opening and the construction of the joint seal becomes difficult.

  In order to cope with such a problem, the following Patent Document 1 proposes a glass support structure in which the glass receiving member 51 is movable from the mounting position to the lower side while being movable from the lower side. In the case of this glass support structure, interlayer displacement is caused from the state of FIG. 14A, and as shown in FIG. 14B, each glass rotates in the same direction, and the upper end corner of the glass is a glass receiving member. Even if it collides with 51, breakage of the glass G is prevented by the glass receiving member 51 moving upward.

  By the way, due to diversification of the curtain wall structure in recent years, there is no frame frame-like panel support material, and only the panel is supported by directly supporting the four corners of the panel (mainly plate glass) or a part of the four corners and side edges. The frameless construction method that constitutes the outer wall surface is becoming widespread. Various structures have been proposed as a panel support structure for the frameless method.

Recently, for example, Patent Document 2 below has proposed a panel support structure that is simple in structure, easy in construction and panel replacement, and further reduces costs. As shown in FIGS. 15 and 16, the support structure of the panel is an upper portion having a fixed bracket 56 fixed to a support member provided in the building structure and a rod connected to the fixed bracket 56 on the back surface. The bracket 53 and the left and right lower brackets 54A and 54B that are divided into two parts and are detachably attached to the upper bracket 53 are square brackets on the front surface, and the plane plate is substantially triangular and opens outward on the front surface side. A plurality of face plate fasteners 55A to 55D provided with face plate insertion holes 55a to be inserted into the corners of the brackets and bracket insertion holes 55b which are opened inward on the back side and inserted into the corners of the brackets 53, 54A and 54B. Is provided.
