The present invention relates to a frame structure of a sliding door installed in an entrance door of a building to be automatically opened and closed in a sliding manner. A vertical frame is connected to the left and the right of tempered glass, and an upper horizontal frame and a lower horizontal frame are connected to the upper and lower sides to be open and closed by sliding. The frame structure of a sliding door includes: a thermal insulation bar having a slot formed in the longitudinal direction by being adjacent to a space unit in which the tempered glass is inserted, and a hanging protrusion inserted into the slot; a forming groove located at the center of an opposite side to the space unit; and azone injected into the forming groove, wherein a frame is divided by the thermal insulation bar, the forming groove, and the azone. The upper horizontal frame includes: a screw groove having the same width as both sides of the forming groove and the slot; an upper installation groove formed on one side in the longitudinal direction; and a packing protruding from the tempered glass at a right angle by being connected to the upper insulation groove. When the upper horizontal frame is connected to an upper assembly groove, the upper insulation groove is exposed to the upper part of the vertical frame. According to the present invention, the frame structure of a sliding door can prevent a thermal loss through the frame, by connecting the upper and lower sides of the center of the frame by different kinds of thermal insulation materials. The frame structure of a sliding door can optimize both productivity and strength. |
