Door and Window Corner Wall Crack Prevention Component Structure (XII) and its Crack Prevention Elements

Abstract

This invention relates to a crack-prevention component structure for door and window corner walls and its crack-prevention element. The crack-prevention element is mainly divided into several quadrant regions, and a guide plate is provided in the stress-reduction section of each quadrant region to connect the stress-reduction sections of the several quadrant regions. This allows the stress acting on the crack-prevention element to be evenly distributed among the stress-reduction sections of the several quadrant regions, thereby improving stress reduction efficiency. Furthermore, the design of a force-guiding zone around the center point of the crack-prevention element, defined by first, second, and third reinforcement sections on its periphery, effectively blocks stress transmission to the center point and guides the stress outward, preventing displacement of the center point due to stress. This ensures the stability of the crack-prevention element installation.
