The utility model relates to an L-shaped hanging wall for an oxy-fuel glass furnace, which comprises an air cooling hanging pillar (1), a group of hanging hooks (2) connected with the air cooling hanging pillar (1), a groups of compound bricks hung on the hanging hooks (2), and a baffle (7), wherein each compound brick is formed by splicing a female buckle brick (5) and a male buckle brick (6) in a matched manner; the female buckle brick (5) is provided with a dovetail groove; and the male buckle brick (6) is provided with a dovetail. The L-shaped hanging wall is characterized in that one of two adjacent rows of male buckle bricks (6) are large bricks, while the other of the adjacent rows of male buckle bricks (6) are small bricks; correspondingly, one of two adjacent rows of female buckle bricks (5) are small bricks, while the other of the adjacent rows of female buckle bricks (5) are large bricks; a brick work joint (4) is formed when one female buckle brick (5) is matched with a corresponding male buckle brick (6); and adjacent brick work joints (4) of the compound brick are staggered with a certain distance. The L-shaped hanging wall has the benefits that as the wall-type parent-subsidiary buckle structural design is adopted, joints of different rows of overlapped compound bricks are staggered, which can effectively prevent the peeling off and the flaking off the bricks of the hanging wall; and due to the reasonable clearance matching between the male buckle bricks and the female buckle bricks, the electrically fused bricks (namely the male buckle bricks) of the hanging wall cannot squeeze the notches of the female buckle bricks broken under thermal expansion during the temperature increment of glass furnace. Therefore, flaking off of the electrically fused bricks is avoided.
