The technology has been used which constructs glass wall by fixing glass panes to a building wall by means of fixing means to obtain the aesthetic appearance and good transparency. But, there occurs a problem that to facilitate the execution for fixing the glass panes as structural elements of the glass wall to the building, employing a single glass pane deteriorates heat insulation and soundproof properties.
To solve the above-mentioned problem, the technology of constructing glass wall with double-glass panes instead of single-glass panes has been disclosed in Korean Patent Publication No. 93-9113 (Glazing units and glass assemblies with an array of a plurality of glazing units) and Japanese Laid-open patent No. Pyung 9-177442 (Multi-layer glass and supporting structure for the multi-layer glass).
The glazing units disclosed in the Korean patent publication No. 93-9113 are sealed double glazing units and comprises a fixing assembly consisting of a fixing bolt, a bush and a boss and fixing the glazing units to the plate member at least one fixing position, wherein the fixing assembly comprising a bush and a boss is attached to one of the glass panes in a manner which permits the unit to flex under wind load without impairing the seal of the unit, and at both sides of a boss located between an outer pane and an inner pane of the unit, an rubber ring is provided. But, to seal the holes punched in an outer pane and an inner pane of the unit, since a lot of processes are required for assembling the fixing elements of the fixing assembly, such as a fixing bolt, a bush, a boss and rubber rings, the above-mentioned invention is inappropriate to the process for mass producing, thereby decreasing the productivity, and since the fixing assembly is fixed to the plate member of a building while it supports any one part of an outer pane and an inner pane of the unit, and thus the safety is deteriorated.
