Combined mould and forming method used for bulged bar prefabricated part forming

Abstract

The invention relates to a combined mould used for bulged bar prefabricated part forming. The combined mould comprises a first molding board and a second molding board, wherein slots perpendicular tothe length direction of the first molding board are formed in the first molding board; the slots communicate with the bottom side of the first molding board; baffle strips which are staggered with theslots are arranged on the second molding board; two notches for placing reinforcing steel bars are formed in one side of each baffle strip; the first molding board is combined with the second moldingboard to form an integrated molding board; and a first bar penetrating hole and a second bar penetrating hole for allowing the reinforcing steel bars to pass through are formed between each slot andthe corresponding baffle strip. After being combined, the mould is good in sealing property, and the holes for just allowing the reinforcing steel bars to pass through are formed in the formed integrated molding board, so that occurrence of leaked slurry is greatly reduced in comparison with waist-shaped holes in the prior art, building materials are favorably saved, and a prefabricated componentwith uniform components is obtained; molding and de-molding are convenient, de-molding difficulty is reduced, and de-molding efficiency is greatly improved; acting force on each molding board is relatively small in a molding process and a de-molding process; and moreover, structural strength of the molding boards is high, so that the molding boards are not liable to damage, and using and maintaining cost of the mould is reduced.

Description

technical field [0001] The invention relates to a combined mold and a molding method for molding prefabricated components with ribs, and belongs to the technical field of concrete moulds. Background technique [0002] Prefabricated concrete components are building components prefabricated in factories with concrete as the basic material, including prefabricated building components such as walls, beams, panels, and columns. Since prefabricated components need to be connected with other components to form strength, protruding steel bars are often reserved on the outer surface of prefabricated components. These reserved steel bars are called ribs because they protrude on the outer surface of the prefabricated components. When the ends of the two ribs of the prefabricated part are connected by steel bars to form a closed structure, the ribs at this time are called stirrups. [0003] Standard concrete prefabricated components are generally cuboid structures, which are hexahedro...
