Anti-cracking trim for wall corners of doors and windows.

Abstract

The invention relates to a crack-resistant assembly for walls at the corners of doors and windows. The surface of each crack-resistant element (1) of the crack-resistant assembly has several ridges (19) and several grooves (18), both of which are spaced apart. The ridge (19) has several reinforced recesses (191). At least one gap (192) is formed on at least one face of the reinforced recess (191) in the crack-resistant element (1). Thus, concrete is not only bonded to the reinforced recesses (191) on the surface of the crack-resistant element (1) while flowing through the surface but is also filled into the gap (192) and covers the protruding piece (193) connected to the gap (192). After the concrete hardens to form the wall structure (7), the bonding area and the connection stability of the wall structure (7) are significantly increased. The crack resistance performance of the corners of door and window frames (41), (42) in reinforced concrete (RC) walls is further improved.
