The invention discloses a conical embedded nut assembly for creeping formwork construction. The conical embedded nut assembly comprises a conical nut, a fixed bolt fixedly connected with the big end of a conical pre-nut, a tail rib fixedly connected with the small end of the conical nut, and a nut rubber sleeve, wherein the shape of the nut rubber sleeve is engaged with the shape of the conical nut, binding port annular reinforcing ribs are arranged at the binding ports of two ends of the nut rubber sleeve, and the nut rubber sleeve wraps the big end plane and the small end plane of the conical nut. An installation method for the conical nut assembly comprises the following steps of: 1) coating butter on the peripheral surface of the conical nut; 2) sheathing the conical nut rubber sleeveon the conical nut; and 3) fixing the embedded nut assembly on one side of a formwork through fixing bolts. The conical nut assembly tightly wraps the conical nut in a 'covering sleeve' shape so as to ensure that a wet concre
