Shaanxi site Hohhot aerial work platform contact phone number: 18420150310 subway leaking without scaffold for subway scaffolding say what are the problems in use process? Here is to introduce to everybody simple analysis under the subway scaffold in the now existing in the use of some shortcomings: one, the construction of the lever is missing, not connected, sweep the floor two vertical and horizontal bar from the distance is too large or too small, etc. ; Scaffold board list, insufficient thickness, overlap does not meet specification requirements; Large formwork dismantling thick inside not for network between rod and wall body; Bracing in plane not continuous; Open the scaffold not brace; Scaffold board under the small bar spacing is too large; Even the inside and outside wall pieces do not rigid connection; Protective railings spacing greater than 600 mm; Fastener connection is not tight, fastener slip, etc. Second, the design 1. Is common at present domestic scaffolding materials such as steel, fasteners, jacking and tap to be of poor quality, in the actual construction failed to consider the theoretical calculation. 2. To heavy tube scaffold should have a clear understanding, generally if the thickness of the floor more than 300 mm, according to the subway should consider the scaffold design, scaffolding load more than 15 kn/was, should organize expert argumentation. To separate the parts of the steel tube length changes on the bearing, the upper free length should be considered for template bracket a shoulds not be too long, it is advisable to generally less than 500 mm ( In the new specification may be revised) , when the poling calculation generally on the top step and the largest stress at the bottom step, should be regarded as the main computing point. When required by the bearing capacity of discontent group should increase the poling reduce step Hohhot aerial work platform where the shaanxi
