The utility model provides a wall superheater's fixed knot constructs. Traditional internal power plant boiler tower furnace does not adopt the structure of wall type over heater, so there is not the technique about the this respect. A wall superheater's fixed knot constructs which constitutes and includes: wall superheater pipe, wall superheater pipe clamp pipe, water cold wall pipe and wear plate, characterized by: wall superheater pipe (2) both ends be connected with wall superheater coupling (1), wall superheater pipe level arrange, water cold wall pipe (4) arrange perpendicularly, use wall superheater pipe clamp pipe (3) carry out a packet clamp with the over heater pipe the package press from both sides the in -process water cold wall pipe that presss from both sides of wall superheater bottom package on add and weld tray (6), and water cold wall pipe and wall superheater pipe between with wear plate (5). The utility model discloses be applied to wall superheater's fixed knot constructs.
