Claims

[Scope of Claim for Utility Model Registration] ■ Insert the lower end of the upper shaft of the embedded collar, which is removably engaged with the embedded collar, into the through hole of the bottom plate of the formwork for manufacturing track slabs, concrete sleepers, etc. and a device configured to fasten the embedded collar to the bottom plate by elastically pulling downward the lower end of the upper shaft of the embedded collar protruding from the lower surface of the bottom plate, the lower end of the upper shaft of the embedded collar being elastically pulled downward. A rod-like elastic member engagement insertion portion is formed in the bottom plate portion, and a horizontal shaft is installed below the bottom plate portion, and this horizontal shaft is capable of reciprocating motion in the axial direction of the horizontal axis by operating from the outside of the bottom plate portion. A rod-shaped elastic member holding fitting is provided, and the rod-shaped elastic member holding fitting is arranged so that the rod-shaped elastic member, which is inserted into and extracted from the rod-shaped elastic member engagement insertion portion as the fitting reciprocates, is aligned with the horizontal axis in a plan view. parallel to each other, and are inclined so that the free end side is located higher in side view, and on the lower surface of the bottom plate part, there is a downwardly facing part facing the free end of the rod-shaped elastic member only on one side of the through hole. A rod-shaped elastic member positioning fitting having an inclined cam surface formed therein is fixed, and as the rod-shaped elastic member holding fitting moves forward, the free end side of the rod-shaped elastic member is pushed down by the inclined cam surface, and the above-mentioned embedded An embedded collar fastening device characterized in that the lower end of the collar upper shaft is configured to be elastically pulled downward by the rod-shaped elastic member. (2) The device according to claim 0, wherein the rod-shaped elastic member engaging insertion portion is a through hole that diametrically penetrates the lower end of the upper shaft of the embedded collar. (2) The device according to claim 0 or 0 of the Utility Model Register, wherein the rod-shaped elastic member is a flat spring that is flat in the vertical direction.
