Anti-cracking assembly structure for door and window corner wall and anti-cracking component thereof

An anti-cracking assembly structure for door and window corner wall, comprising:

• a plurality of anti-cracking components, arranged at intervals and corresponding to each other, wherein each of the anti-cracking components has a first piece portion arranged longitudinally, a second piece portion arranged laterally, a notch jointly formed on one side of the first piece portion and the second piece portion, and at least two adjacent fixing holes respectively arranged at end edges of the first piece portion and the second piece portion at the side of the notch, wherein the first piece portion and the second piece portion are perpendicularly connected and integrally formed;
• a plurality of fixing rods, each fixing rod penetrating and being secured in a respective one of the fixing holes correspondingly arranged in the first piece portion and the second piece portion of each of the anti-cracking components, wherein the first piece portion has two virtual longitudinal sidelines defined thereon to respectively pass through a corresponding one of two of the plurality of fixing rods longitudinally, wherein the second piece portion has two virtual lateral sidelines defined to respectively pass through a corresponding one of another two of the plurality of fixing rods laterally, wherein each of the anti-cracking components has an operation area defined respectively between the two virtual longitudinal sidelines and the two virtual lateral sidelines and the end edges of the first and second piece portions, wherein the operation area has at least one positioning hole formed therein;
• and
• at least one positioning rod being inserted through the at least one positioning hole of the anti-cracking components that are correspondingly arranged, and fixed on a formwork, wherein each of the anti-cracking components has a plurality of protruding ribs and grooves formed on a surface thereof, wherein each of the grooves is formed between two adjacent protruding ribs so that the protruding ribs are arranged in spaced relationship, wherein the protruding ribs and the grooves are formed in a circular arc contour with increasing diameters from inner end edges of the of the first piece portion and the second piece portion to an interface between outside edge portions of the first piece portion and the second piece portion, and arranged concentrically each with respect to the others, and wherein each of the ribs has a plurality of reinforcement dimples formed in angularly spaced relationship therein along the circular arc contour thereof, and each of the grooves has a plurality of through holes formed therethrough and arranged in angularly spaced relationship along the circular arc contour thereof.
