Construction key of wall track type B.M.U
Construction points
The window track along the inside of the parapet on the layout, embedded part is composed of 1 blocks of 10 ~ 16mm thick embedded steel plate and 6 or 16 Phi Phi 20 embedded steel bars. With a nut embedded steel and embedded steel plate fixed, pouring parapet will track with parapet pouring embedded one, embedded steel and concrete surface performance level. After the completion of the construction, the other steps are the same as the horizontal track type.
The design and installation of the track system of the aircraft should pay attention to the following points in addition to the above horizontal track points:
The wall structure must have height, thickness and strength enough, otherwise it will be unable to meet the anchorage length of embedded parts and effects of window cleaning machine safety, should be combined with the construction structure of the base is arranged on the wall or thick wall daughter, in order to reduce the effect of window cleaning machine load roof structure;
The rail connections must be polished to a rail end end head baffle thickness not less than 10mm;
(3) it is necessary to set enough height for the equipment to walk, and take full account of the space occupied by the building decoration, so as to prevent the building from colliding with the building when the lower part of the equipment meets the roof or the suspension platform to recover the roof.
