The rail type window cleaning machine is connected to the structural panel of the building through a rail system, and the gauge distance is generally 0.8 to 4.0 m, and the two rails can be arranged in one plane or not in one plane. The track system consists of a base, a connector and a track. Before the structure is capped, the window cleaning machine base is cast, the base should be higher than the roof surface layer by more than 80mm, and the base embedded part is composed of a 10~16mm thick embedded steel plate and four φ16 or φ20 anchor bolts. After the construction is completed, the pre-embedded steel plate is adjusted to the same plane by adjusting the nut on the embedded bolt, the secondary grout is fixed after the secondary grout fills the gap, and then the rail is fixed on the pre-buried steel plate by the rail connecting member (pressing plate). The window of the window cleaner is made of I-shaped steel or H-shaped steel. Generally, the track is directly welded to the embedded steel plate. After the track is installed, the base and the roof are unified to resist the treatment.
