Claim Text:
1. A sliding window installation structure including a guide frame, including upper and lower guide frames, of a separable and removable segment structure, in which a glass panel forming a sliding window constituting a part of a sliding window system is removably seated on and supported by rollers without a separate sash that supports the glass panel, and an upper and a lower pocket guide are respectively formed in the upper and lower guide frames, forming a window frame member that guides and supports a smooth movement of the sliding window so as to guide an upper end and a lower end of the sliding window along an inner and an outer surface of the sliding window; characterized in that vertical stiffeners with a first thickness on both inner and outer surfaces of the sliding window for the upper end and the lower end of the sliding window and with a second thickness for a center region between the upper end and the lower end of the sliding window are attached to both a left-side and a right-side of the glass pane that constitutes a part of the sliding window including the glass panel supported by the rollers so as to reinforce a transverse bending rigidity of the glass panel, wherein the second thickness is larger than the first thickness; and wherein in order to allow the sliding window provided with the vertical stiffeners to be integrally installed within the upper and lower guide frames, and to allow the sliding window provided with the vertical stiffeners to be separated from the upper and lower guide frames, said upper and lower pocket guides configured to guide and support the upper end and the lower end of the sliding window with an upper end and a lower end of the vertical stiffeners having the first thickness are installed to be separable from a guide frame body, wherein the guide frame body and said upper and lower pocket guides constitute the upper and lower guide frames, in a direction parallel to a travel direction of a roller guide rail installed on a base surface of the guide frame body including an opening having a size larger than the first thickness of the vertical stiffeners, in which said upper and lower pocket guides comprise a plurality of pocket guide segments removable from the guide frame body, and said pocket guide segments are successively installed to be separable from each other on said inner and outer surfaces of the sliding window along the travel direction of the roller guide rail.
