Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a support structure for a large glass surface constituting an outer wall surface of a building.
[0002]
[Prior art]
Recently, a so-called glass screen construction method in which the entire outer wall of a building is composed of a plurality of glass plates has been adopted in order to make the appearance of the building a unique design and to improve the feeling of freedom in the room.
[0003]
As shown in FIG. 9, this construction method supports a plurality of glass plates 21 with a dot point support 3 and supports the dot point support 3 on a support column 8 erected between a floor 21 and a beam (not shown). It is to be fixed. Although the surface pressure (wind pressure, seismic force) applied to the glass plate 21 is normally received by the support column 8, the dot point support 3 that is not fixed to the support column 8 cannot resist the surface pressure.
[0004]
Therefore, the dot point supports 3, 3... Provided between the support columns 8, 8 are assembled with trusses 9 made of wires or steel frames, and a glass screen made up of a plurality of glass plates 21 functions sufficiently as an outer wall of the building. I am doing so.
[0005]
[Problems to be solved by the invention]
However, the above glass screen construction method can create a unique design, for example, a sense of transparency and a sense of freedom of the entire building, but it impedes maintenance and management. For example, when the truss 9 is formed of a wire, there is no problem in appearance design, but since the wire truss protrudes greatly toward the indoor side, maintenance such as cleaning from the indoor side to the glass plate 21 becomes difficult.
[0006]
On the other hand, in order to facilitate the maintenance of the glass plate 21, when the support pillar 8 is provided corresponding to the dot point metal fitting 3 or the truss is configured with a steel frame, the created design unique to the building, especially the transparency ( The feeling of liberation) will be greatly reduced. The present invention provides a support structure for a large glass surface that can easily maintain the indoor side of a glass screen without constituting a truss made of the above-described wire or steel frame and without reducing the transparency.
[0007]
[Means for Solving the Problems]
The present invention provides a structure for supporting the indoor side of a large glass surface constituted by supporting corners of a plurality of glass plates supported by a support, and is a long flat plate extending in the vertical direction on the indoor side of the large glass surface. The glass rib is disposed with the side end face of the rib facing the glass plate, the support is attached to the glass rib, and the vicinity of the floor side of the glass rib is a steel column erected on the floor. It is related to the support structure of the large-sized glass surface characterized by having connected. Further, the invention is characterized in that the support tool is pulled by the ceiling side casing through a suspension wire. Further, the present invention is characterized in that a lighting device is incorporated in a connecting portion between the glass rib and the steel column.

FIG. 3 is a side view for explaining the glass screen construction method in more detail.
One glass rib 4 is provided between the floor 12 and the frame beam 13. The glass rib 4 is made of a long flat plate-like tempered glass or laminated glass, and is arranged with its side end face opposed to the glass plate 21.
The glass rib 4 is arranged in a state orthogonal to the glass plate 21. Therefore, only the end face of the glass rib 4 is observed from the outside of the building through the glass plate 21, and the transparency of the glass screen is not impaired.
However, in the vicinity of the floor 12, when a person or a cart passes or uses a floor cleaning tool, these abut against the glass ribs 4 near the floor, and even if the ribs are tempered glass or laminated glass, they are damaged. Become. In order to prevent this, a structure in which the steel rib 5 bears the glass rib 4 from the floor 12 to a predetermined height is adopted. Then, by fixing the dot point support 3 to the steel column 5, the surface pressure strength of the glass screen is increased.

That is, the enlarged view of FIG. 4 is a diagram showing a configuration in which the upper part of the glass rib 4 is attached to the frame beam 13.
The glass rib 4 provided on the indoor side of the glass plate 21 has a holding metal fitting 41 attached to the upper portion thereof, and is fixed to the ceiling-side frame beam 13 via the attachment metal fitting 14. Similarly, the lower part is fixed on the floor 12 via a fixing bracket (not shown). A suspension wire 6 for lifting the dot point support 3 is connected to a suspension 61 attached to the lower surface of the frame beam 13.
[0011]
FIG. 5 is an enlarged view of a portion B in FIG. 3, (a) is a side view, and (b) is a front view.
A corner where four glass plates 21 are gathered is supported by a single dot point support 3, and this support retains dot fixing portions 31 and glass ribs 4 for fixing the corners of each glass plate 21. . It consists of a rib holding part 32 and a joint part 33 that connects the fixing part and the holding part.
Both are screwed through the perforated glass holes.
The dot fixing part 31 is provided with a wire fixing part 34, and the hanging wire 6 is pulled between the hanging tool 61.

【The invention's effect】
According to the support structure for a large glass surface of the present invention described above, the glass rib exhibits sufficient strength as a stiffening beam against the surface pressure received by the plurality of glass plates.
Moreover, since the glass rib has its side end face opposed (orthogonal) to the glass plate, the glass rib has a minimum occupied area with respect to the large glass surface.
That is, rather than impairing the sense of transparency and release in the room, it can be increased.
Moreover, since the glass ribs are erected in the vertical direction and the short sides thereof are protruded to the indoor side, maintenance such as cleaning of each glass plate is not hindered.
In addition, by turning on the built-in lighting fixture, it becomes possible to create a unique atmosphere in the large glass surface.
