PROBLEM TO BE SOLVED: To facilitate inventory control of head jambs for single sliding door frames, easily constitute a head jamb with high accuracy in which outer ends of a long head jamb member and a short head jamb member are aligned, and prevent opening/closing difficulties such as rattling and rubbing from occurring.SOLUTION: A single sliding door frame structure, in which a head jamb 10 comprises a long head jamb member 11 and a short head jamb member 12, is characterized in that: a joint guide member insertion groove 14 is provided along the longitudinal direction on each of opposing surfaces of the long head jamb member and the short head jamb member; a fixing groove 19 is formed along the longitudinal direction of the long head jamb member; a fitting ridge 15 is formed on the short head jamb member; and a depth of the joint guide member insertion groove 14 is larger than a protrusion dimension of the fitting ridge 15. Further, the head jamb is assembled to the single sliding door frame by inserting a plurality of short-formed joint guide members 20 into the joint guide member insertion groove 14, aligning outer end parts of the long head jamb member and the short head jamb member, and thereafter, inserting the fitting ridge into the fixing groove. |
