Anti-condensation structure of building water supply and drainage pipeline

The utility model relates to the technical field of drainage pipeline anti-condensation, in particular to a building water supply and drainage pipeline anti-condensation structure which comprises a drainage pipeline body, an anti-condensation mechanism is movably connected to the lower portion of the outer surface of the drainage pipeline body in a penetrating mode, and an upper connecting plate is movably connected to the upper portion of the outer surface of the anti-condensation mechanism. The upper connecting plate and the anti-condensation mechanism are both in contact with the outer surface of the drainage pipeline body, a plurality of heating wires are arranged in the upper connecting plate, the heating wires are electrically connected with an external power supply through wires, and therefore the heating wires can operate to heat the outer surface of the drainage pipeline body, and condensation is avoided. According to the anti-condensation structure for the water supply and drainage pipeline of the b
