cleaning machine is connected to the building structure through the track system, and the gauge distance is generally 0.8-3.0 m, and the two tracks can be arranged in one plane or not in one plane. The track system consists of a base, a connector and a track. The susceptor of the pedestal consists of one pre-embedded steel plate and four φ16 anchor bolts. The pre-embedded bolts are fixed with the pre-embedded steel plates with nuts, and the base of the sand-filling machine is placed before the roof of the building structure. The height-degree should be higher than 80mm above the roof surface. After the pedestal is completed, the pre-embedded steel plate is adjusted to the same plane by adjusting the nut on the embedded bolt. After the secondary grout fills the gap, the embedded steel plate is fixed, and the track is fixed on the embedded steel plate by the rail connecting member (pressing plate). . The window of the window cleaning machine is made of I-shaped steel or H-shaped steel. Generally, the track is directly welded to the embedded steel plate. Due to the advantages of simple construction, reliable operation, and smooth operation of the window cleaning machine, it is widely used. After the track is installed, the pedestal and the roof are unified to make water treatment.
