It has a split nut, a split nut receptor, and a split nut biasing body, and the split nut receptor is attached to the shank of a bolt or the like prior to the split nut. Further, the split nut receiver has a split nut receiving recess at the rear end surrounding the above-mentioned shank, and this receiving recess is formed in a mortar shape so that the inner diameter gradually decreases toward the back, The nut consists of an appropriate number of split nut constituent pieces located in the receiving recess and surrounding the shank, and the split nut biasing body includes:
It is screwed into a split nut receiver at an appropriate position and gradually presses the rear end of the split nut exposed from the receiving recess as it is twisted, and is biased by the split nut biasing body. A tightening structure for a bolt or the like, characterized in that the split nut receives a reaction from the mortar-shaped tapered surface of the receptor recess and generates a tightening force toward the center of the shank. 2. The bolt, etc. according to claim 1, wherein the bolt is a separator for fastening concrete formwork, and the split nut biasing body has a bolt for fastening concrete formwork extended at the rear thereof. Tightening structure. 3. The bolt or the like according to claim 1 or 2, wherein the split nut receiving recess has an elastic body on the inner bottom thereof for biasing the split nut toward the opening of the receiving recess. Tightening structure.
