Description

  The present invention relates to the glass support structure in a curtain wall structure that is supported by a self-weight receiving member in which the self-weight of the glass is fixed in a vertical direction without having an eyelessness.

  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 a feeling of opening, and glass is supported only by a vertical.

  Specifically, as shown in FIG. 17, 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 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. 18 (A), and as shown in FIG. 18 (B), 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.
JP 2000-45437 A

  However, when the glass receiving member 51 can be moved upward with respect to the vertical as in Patent Document 1, the mounting structure for the vertical is complicated, and the slide guide portion is formed in the vertical. In other words, the vertical cross-sectional shape is complicated.

  Therefore, a main object of the present invention is to provide a glass support structure that can surely prevent breakage of glass at the time of interlayer displacement, and that the structure is simple and the construction can be simplified.

In order to solve the above-mentioned problems, the present invention according to claim 1 has a curtain wall structure that has no weight and is supported by a self-weight receiving member that is fixed in a vertical manner.

  In the present invention described in claim 1, the cradle for supporting the lower end corner of the glass is supported so as to be rotatable upward. Therefore, even if the glass causes interlayer displacement, each glass rotates in the same direction, and the upper end corner of the glass collides with the rotation support base, the glass breaks due to the rotation support base rotating upward. Will be prevented. In addition, it is only necessary to attach to one place, and there is less processing for the vertical, so that the construction can be simplified.

  According to a second aspect of the present invention, there is provided the glass support structure in the curtain wall structure according to the first aspect, wherein the rotation support base is rotatably supported by an axis oriented parallel to the glass surface.

  According to a third aspect of the present invention, there is provided the glass support structure in the curtain wall structure according to the second aspect, wherein a sliding surface for guiding the upward movement of the glass is formed on the lower outer surface portion of the base material. The

  As a fourth aspect of the present invention, there is provided the glass support structure in the curtain wall structure according to the first aspect, wherein the rotation support base is rotatably supported by an axis oriented along the indoor / outdoor direction. .

  According to a fifth aspect of the present invention, there is provided the glass support structure in the curtain wall structure according to the fourth aspect, wherein the left and right rotation support bases are supported by a single rotation shaft.

  As the present invention according to claim 6, both side edges of the glass are fitted into glass fitting grooves formed along the vertical direction of the vertical, respectively, on the outdoor side and indoor side of the glass side edges, respectively. The glass support structure in the curtain wall structure according to any one of claims 1 to 5, wherein watertightness and airtightness are ensured by the installed elastic packing and / or seal.

  As described above in detail, according to the present invention, it is a glass support structure that can reliably prevent the glass from being broken at the time of interlayer displacement, the structure is simple, and the construction can be simplified.
