Thus, according to the plate glass support structure of the present embodiment, it is not necessary to screw the gripping member 18 attached to the rib plate glass 14 to the rib plate glass 14. Therefore, even if the glass wall surface 10 receives a lateral external force such as wind pressure, local stress does not occur locally as in the prior art, and therefore the rib plate glass 14 can be effectively prevented from being damaged. .
[0023]
In addition, since it is not necessary to accurately position the bolts during construction, the construction can be performed easily and quickly.
Furthermore, by eliminating the need for bolt connection, the rib plate glass 14 can be formed of a single plate, and by eliminating the need for drilling, the manufacturing cost can also be reduced.
[0024]
Moreover, since the holding member 18 can be reduced in size, the appearance exposure can be reduced, and the design is improved.
Here, the rib plate glass 14 may use tempered glass or general float glass, but the tempered glass has a very small size compared to the general float glass because of the limitation in manufacturing, When configuring a large wall surface, a large plate of general float glass may be used.
[0025]
In addition, the gripping member 18 attached to the rib plate glass 14 does not expose bolts and the like in appearance, and can have a relatively compact configuration, so that the design of the glass wall surface 10 is also improved.
