The arc-shaped limiting plate is attached to the semi-circular template to ensure the alignment of the semi-circular template and the forming main mold, and prevent the semi-circular template from rotating and opening under the extrusion of the mortar inside the mold during the fixed mold construction of road and bridge buildings.

[0009] 2. A set of limiting plate convex plates of the present utility model prevent the arc-shaped limiting plate from sliding out of the U-shaped fixing sleeve during the fixed mold construction of road and bridge buildings. The arc-shaped plug plate is inserted into the semi-circular jack, and the semi-circular jack is blocked by the arc-shaped plug plate, which prevents the mortar in the mold from flowing out of the semi-circular jack during the fixed mold construction of road and bridge buildings. At the same time, it prevents the formed parts after molding from having steps at the semi-circular jacks and affecting the overall structure of the formed parts during the fixed mold construction of road and bridge buildings. The sliding baffle is fixed on the forming main mold through a set of arc-shaped fixing rods, and at the same time, the sliding baffle can slide. The sliding baffle makes the plug plate outer plate inserted into the sliding baffle, and the symmetrical sliding baffles position the plug plate outer plate, which prevents the arc-shaped plug plate from sliding out of the semi-circular jack during the fixed mold construction of road and bridge buildings. When it is necessary to segment and form the formed parts, the forming partition plate is inserted into the semi-circular jack. When it is not necessary to segment and form the formed parts inside the mold, the arc-shaped plug plate is inserted into the semi-circular jack. This device has multiple forming structures, and only the forming partition plate and the arc-shaped plug plate need to be installed according to needs, which is convenient for operation.
