The invention relates to the field of a tension member of threads capable of fastening or being tensile and used for a template, and specifically relates to a split bolt used for rapid construction and a using method thereof. The split bolt used for the rapid construction includes templates (11), longitudinal supporting bars (12) and transverse supporting bars (13), and is characterized in that the split bolt further comprises a double-headed screw rod (2), gaskets (3), outer screw rods (4), clamping hoops (51) and nuts (52), and the double-headed screw rod (2) is disposed between the two opposite templates (11); and the inner ends of the outer screw rods (4) are screwed into screw holes of end faces of the double-headed screw (2), and the outer ends of the outer screw rods (4) are sequentially sleeved by the clamping hoops (51) and the nuts (52). The using method of the split bolt used for the rapid construction is characterized in that the method is implemented in order according tothe steps: a. supporting the templates; b. pouring; and c. unloading the templates. The split bolt and the using method are simple in structure, are convenient to construct, and are wide in suitable range.
