Template connecting structure for civil engineering

The utility model belongs to the technical field of building equipment, and particularly relates to a civil engineering formwork connecting structure which comprises a connecting frame, a bolt is spirally connected to the inner side of the right end face of the connecting frame, a bilateral rack is rotationally connected to the left end of the outer side of the bolt, and gears are meshed with the top end and the bottom end of the bilateral rack. An operator rotates the bolt on the inner side of the connecting frame, the bolt rotates to move out rightwards on the inner side of the connecting frame, the bolt moves rightwards to drive the bilateral rack to move rightwards, the bilateral rack moves rightwards to drive the two gears to rotate, the two gears rotate to drive the two connecting rods to rotate, and the two connecting rods rotate to drive the two connecting blocks to move oppositely. The two connecting blocks oppositely move to respectively drive the two sliding blocks to oppositely move in the extrusi
