(1)The rail type window cleaning machine is connected with the building structural board through the track system, and the track gauge is generally 0.8 to 4.0m, and the two tracks can be arranged on one plane or on the other plane. The rail system consists of three parts, the base, the connecting piece and the track. In the front window cleaning cap structure pouring machine frame, the base height should be higher than the roof surface layer above 80mm base, every 1500 ~ 2500mm a base, embedded part is composed of 1 blocks of 10 ~ 16mm thick embedded steel plate and the 4 Phi Phi 20 or 16 anchor bolts, the base after the construction through pre buried bolt nut on all the embedded steel plate to the same plane, the two grouting fill the gap after fixing embedded steel, finally track connections (plate) will track fixed on the pre buried steel plate. The rail of the window cleaning machine is made of I-shaped steel or H steel, and the track is directly welded on the embedded steel plate. After the track installation is completed, the base and the roof are unified waterproof.
(2) in the design and installation of standard common rail type window cleaning machine of the rail system should pay attention to the following points:
Consider the window cleaning machine each part weight, track weight, weight, force caused by lateral force and wind load caused by the operation of the;
The design of rail base should be consistent with the building module and convenient construction, set aside enough concrete pouring and vibrating space (such as pouring hole), when the high parapet shall refer to the window size and performance appropriate to enhance the height of the base track;
The supporting point of the track should not be too dense, spacing of not less than 1.5m, the maximum load will be considered as the simply supported beam support rail, the deflection of the rail deformation should not exceed the span of 1/500;
The rail anchor and connecting accessories design strength should be rated load can withstand more than 2 times, the anchor embedded parts should meet the requirements of architectural design, track, attachment and anchors should be anti rust and anti-corrosion treatment; the considering temperature changes caused by thermal expansion and contraction of the rail impact on the rail connection point and roof device the length of each track is not greater than 9m, the expansion gap is not greater than 3mm, circular turning trajectory should not be set expansion joints, and to ensure that the two rail joints staggered position above 2000mm. The temperature profiles in the area to try to use a small section of the orbit, in order to reduce the influence of temperature stress on rail connection point and the roof device;
The rail end shall be welded to the limit baffle, baffle thickness not less than 8mm, width of not less than the track width, height limit device should meet the requirements, generally not less than 100mm;
We should use the welding when the track in the base joint, should be galvanized steel lap welding a length not less than 200mm, width of not less than the track width 20mm, thickness of not less than 12mm in the bottom of the track.
