おける支持脚の着脱構造。[Claims for Utility Model Registration] A removable tubular formwork for secondary lining that is assembled into a substantially circular shape on the inner wall surface of a tunnel that has been primarily lined, and a primary lining surface that protrudes radially from the inside of the formwork to the outside. a plurality of support legs that come into contact with the formwork, and a bracket that protrudes inward of the formwork to removably hold the support legs, and each of the support legs provides a space between the formwork and the primary lining surface In the formwork for secondary lining, which maintains a predetermined gap between the support legs and supports the formwork only by the support legs: the support legs are inserted through intermediate sleeves screwed onto the brackets, and It is characterized in that it is removably locked and fixed to the intermediate sleeve by driving a pair of tapered wedges into rectangular wedge holes bored in the radial direction of the legs and the intermediate sleeve. Detachable structure for support legs in formwork for secondary lining.
