Inner glass skin structure for double glass skin

An inner glass skin structure for double glass skin, the inner glass skin structure being arranged inside a glass curtain wall with a predetermined spacing therefrom using the glass curtain wall as an outer glass, the inner glass skin structure comprising:

• a plurality of sashless plate glasses arrayed in a sliding door formation to be placed inside the outer glass with the predetermined spacing therefrom facing against the outer glass, each edge of four sides of each said sashless plate glass being covered with an aluminum covering material;
• a door roller fixed on a bottom of each said plate glass, on at least one of (a) an indoor side, (b) an outdoor side, and (c) both (a) and (b), among the plurality of sashless plate glasses in the sliding door formation intervening the aluminum covering material therebetween, the indoor side being a place opposite of the glass curtain wall with respect to the sliding door formation and the outdoor side is a place on the glass curtain wall side with respect to the sliding door formation;
• a securing foot member fixed on the bottom of each said plate glass, intervening the aluminum covering material therebetween, to which the door roller is not fixed;
• a lower rail member arranged on a floor underneath the plurality of sashless plate glasses the lower rail member being supporting movably on the bottom of each said plate glass for the inner glass intervening the door roller or being supporting fixedly on the bottom of each said plate glass for the inner glass intervening the securing foot member therebetween;
• an upper rail member arranged on a ceiling directly above the plurality of sashless plate glasses configuring a pair of said plate glass with the lower rail member, the upper rail member supporting the plate glass pair at a respective top movably or immovably,
• wherein the aluminum covering material of each of said plate glasses having an approximate U-shape in cross-section comprises an end face cover part that covers an end face of a respective said edge of each said plate glass, an inner face cover part that covers an indoor-side-facing surface on a periphery of the respective edge of a corresponding said plate glass, and an outer face cover part that covers an outdoor-side-facing surface on the periphery of the respective edge of the corresponding plate glass;
• the covering material for covering the top and bottom of each said plate glass is fixed on the respective edge of the corresponding plate glass through a bonding of an inside face of the end face cover part to an elastic intervening piece secured on the end face of the corresponding plate glass;
• the covering material that covers both lateral sides of the corresponding plate glass is provided with a coupling plate retaining section formed inside the end face cover part thereof, the coupling plate retaining section accommodating a plurality of coupling strip plates arranged therein along the inner face thereof in a series formation with a predetermined regular mutual spacing retaining only both lateral sides of each coupling strip plate to permit free movement thereof along a longitudinal direction of the end face cover part;
• and
• the plurality of coupling strip plates arranged in the coupling plate retaining section are fixed on the end face of the corresponding plate glass by bonding the plurality of coupling strip plates to the elastic intervening piece secured on the end face of the corresponding plate glass and thereby the coupling strip plates in the coupling plate retaining section are secured on the end face of the corresponding plate glass.
