DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for supporting a glass curtain wall or the like constituting an outer wall of an atrium, and more specifically, a vertical member and a horizontal member for supporting a curtain wall are arranged in a grid pattern. A curtain wall support portion.

[0002]

2. Description of the Related Art For example, an outer wall made of an atrium glass curtain wall has a large scale and a very large width. In such a case, if the size of the vertical and horizontal members is increased and the number of used members is increased in order to cope with them, they become more conspicuous than necessary, which impairs the design appearance on the exterior surface due to the use of the glass curtain wall. May have consequences. Therefore, conventionally, as shown in FIG. 4, a plane truss 11 in which the horizontal member 2 is one of the two chord members 10 is provided to counter the horizontal load. 1
Is a vertical member, 4 is a curtain wall, and 12 is a diagonal member of the horizontal truss 11.

[0003]

However, according to the above-mentioned conventional technology, it is possible to structurally cope with an increase in the scale of the outer wall, and it is necessary to increase the length of the vertical and horizontal members and to use the multi-use. Although the influence on the design can be reduced, the diagonal members of the truss placed in a relatively crowded state can be seen from the bottom up, so that the influence on the design is also large. An object of the present invention is to reduce the influence of the structural aspect on the design of the outer wall.

[0004]

According to the present invention, a supporting portion of a curtain wall according to the present invention is characterized in that a horizontal or substantially horizontal structure plate having a set width in the inward and outward directions and having a light transmitting property is constituted by a glass plate, One end of the glass plate in the width direction is fixed to the horizontal member, and the other end facing the one end is attached to the other end.
The point is that the second horizontal member is fixed . And the second
It is preferable to have a diagonal member for supporting the second horizontal member on the vertical member .

[0005]

The glass plate having a width in the inward and outward directions and capable of supporting a horizontal load in the same manner as a conventional flat truss is a light-transmitting glass plate. Structural plates are less likely to dissolve into the surroundings and stand out. Soshi
And fix the second horizontal member to the structural plate made of the glass plate
Therefore, it is easy to obtain a glass that satisfies the required functions such as tempered glass, and it is easy to prevent breakage of the glass plate during handling such as loading into the site or installing, even though the glass is brittle compared to steel plate etc. . In particular, the second
When implementing with a diagonal material that supports the horizontal material to the vertical material
From the glass plate through the diagonal and the second horizontal
The structural plate is supported by the vertical members.

[0006]

Therefore, according to the present invention, the influence of the structural aspect on the design appearance can be greatly reduced, and it is possible to cope with the enlargement of the outer wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, an outer wall of an atrium is constructed by attaching a glass curtain wall 4 to a support portion 3 in which vertical members 1 and horizontal members 2 are arranged in a grid. I have. The vertical member 1 and the horizontal member 2 are structural members,
For this, a steel frame member having a cross-sectional shape such as an H shape, a square ring shape, or a ring shape can be used, but a structural material of another material may be used. The support portion 3 includes a colorless and transparent tempered glass plate 5, which is an example of a horizontal-position structural plate having a set width in the inward and outward directions and having light transmittance. The tempered glass plate 5 is fixed to the horizontal member 2 at one edge in the width direction. A second horizontal member 6 is fixed to the other end of the tempered glass plate 5 in the width direction. As shown in FIG. 3, the structure for fixing the tempered glass plate 5 to the two horizontal members 2 and 6 is a structure in which the edges are fitted into grooves formed in the horizontal members 2 and 6 and fixed. In addition, the tempered glass plate 5 is formed in a trapezoid having one end as a long side and the other end as a short side in plan view, and the reinforcing material 7 is fitted and mounted on the oblique side.
And the support part 3 has the diagonal member 8 which makes the 2nd horizontal member 6 support the vertical member 1. In the above configuration, the strengthened glass plate 5 fixed to each horizontal member 2 can counter the horizontal load acting on the outer wall. By the way, to give an example of real numerical values of each part, the span S is 16800 mm and the interval D between the longitudinal members 1 is 28
00 mm, the distance d between the horizontal members 2 is 4500 mm, the width L of the tempered glass plate 5 is 1100 mm, and the thickness t of the tempered glass plate 5 is about 19 mm.
