Abstract

A molding device includes at least two component form boards 12, 13 and a wedge-shaped spacer board 14 between them. An operating means is associated with the form boards and the spacer, and moves them relative to one another. The operating means 25 includes at least one rack member 18, and at least one lever 26 connected with a pawl 28 which swings about an axis eccentric with the axis of the lever. The pawl 28 engages with the rack 18 and moves the rack forward when the lever is operated.

。[Claims for Utility Model Registration] 1. A wedge-shaped part that is spread toward the end is sandwiched between the left and right panel parts, and the outer edge surfaces of the bases of the left and right panel parts and the side surfaces of the corresponding wedge-shaped parts touch each other at the abutment surfaces. A force transmission mechanism for pulling or releasing the tension on a panel part by fitting and separating the beam-shaped parts of a combination type frame for concrete wall casting that is assembled so as to be connected, wherein the mutual abutting surfaces a bearing stand provided with at least one bearing hole provided on one side; a rack attached to the other side along the attachment/detachment direction of the insert body; A rotary lever is provided with a shaft to which the rotary lever is pivotally fitted, and is provided with an upright protrusion, and when the rotary lever is rotated about the shaft, it engages with the rack and brings the contact surfaces together. A force transmission mechanism for a mold frame, which is provided with a ratchet transmission means for rotation so as to move the mold frame relative to each other. 2. The ratchet transmission means includes a camshaft protruding from the rotary lever so as to be eccentric with respect to the rotary shaft pivotally fitted in the bearing hole, and a base end of the camshaft that is rotatably pivoted to the camshaft. a pawl bar supported at its free end and having a ratchet pawl that engages with the rack; and a detent pawl bar that is pivoted on the outside thereof concentrically with the rotation axis to prevent the pawl bar from returning. The force transmission mechanism according to claim 1, comprising: 3. Two ratchet pawls are formed on both sides of the free end of the pawl bar, facing away from each other.
The force transmission mechanism described. 4. A force transmission mechanism according to claim 2, wherein two ratchet pawls are formed oppositely to each other on opposite sides of the free end of said detent pawl bar. 5. The force transmission mechanism according to claim 1, wherein the rack and the bearing stand are each provided with a stopper that protrudes from one end and abuts against each other for positioning. 6. The force transmission mechanism according to claim 1, wherein two bearing holes are arranged in parallel at an appropriate distance in the bearing stand.
