Abstract:
1. A wall corner strip adapted to form a right angle wall corner, comprising: a first board with a first width, having a first end, a second end, a first external surface, a first internal surface, and an inflexed hook extended inwardly from the second end of the first board to form an outer inflexed angle of 90° between the first external surface and the inflexed hook of the first board, and an inner inflexed angle between the first internal surface and the inflexed hook of the first board, a second board with a second width, having a first end, a second end, a second external surface, a second internal surface, and an inflexed hook extended inwardly from the second end of the second board to form an outer inflexed angle of 90° between the second external surface and the inflexed hook of the second board, and an inner inflexed angle between the second internal surface and the inflexed hook of the second board, wherein the first width of the first board is larger than the second width of the second board, the first end of the first board and the first end of the second board are connected together to form a right angle between the first external surface and the second external surface, and an inner angle between the first internal surface and the second internal surface, and a solid protruding edge extended outwardly from a connecting part of the first end of the first board and the first end of the second board, wherein both thickness of the first board and the second board are increased gradually from the first ends of the first board and the second board to the second ends of the first board and the second board respectively, so that the inner angle is less than 90° and the inner inflexed angles are larger than 90°.
