Abstract: The present invention relates to an anti-cracking assembly structure for door and window corner wall and anti-cracking component thereof. The anti-cracking components of the anti-cracking assembly structure for door and window corner wall has a plurality of protruding ribs and grooves formed at intervals on a surface thereof. The protruding ribs and grooves are arc-shaped and arranged in parallel to each other. When the reinforced concrete wall is subjected to an external force and stress is generated at the corner of the door and window frames, the stress can be guided along the arc-shaped protruding ribs and arc-shaped grooves on the surface of anti-cracking component to change the transmission direction of the force at the stress end, so as to transmit and disperse the stress to the peripheral side more quickly. Accordingly, it can more effectively prevent the occurrence of 45-degree shear cracks at the corners.
