Q:What are the common rules for calculating the amount of scaffolding works: According to the wall masonry scaffolding (single) vertical projection area calculation with square metre.Scaffolding, without deduction of door and window opening, air ring, vehicle channel, deformation joint area. At the same time, the height of the same building is different, according to the vertical height of the building.

Q:What is the mobile scaffolding materials: The overall life of cold galvanized mobile scaffolding accessories for about 5 years, the surface does not require maintenance, moderate cost. The main processing technology: the welding of the scaffolding parts and then galvanized, the surface of each part, are galvanized

Q:What heights do u need a harness for(had to repost as didnt explain correctly in last 1): OSHA says that you need guardrails, safety nets or a fall-arrest system if you're working or walking near an unprotected surface more than 6' above a lower level.

Q:Scaffolding installation and precautions?: The backing plate and the base should be placed on the positioning line accurately.2, when the erection of the column, the outer diameter of the steel pipe is strictly prohibited, the adjacent column of the docking fasteners shall not be in the same height, staggered distance should meet the structural requirements.

Q:What are the dangers of scaffolding: The scaffold and bar for use of instability, binding is not strong or break and fall; the improper operation of the impact and accident etc.;Improper operation generally have the following situations:A. overexert, causing physical instability;B. in the frame and pull the car back walking;C. crowded collision;D. many people handling or installation of heavier components;Ice and snow on the E. frame is not clear, causing the slide.

Q:hi guys i got my scaffold piercing a couple of days ago and it keeps bleeding on and off and there was dry blood but i removed it and its bleeding more what could i do step by step to keep total care of my piercing to get rid of all these problem please help it will really be appreciated: leave the dry blood let it heal be patient

Q:i already found the force in rope 2 but im not getting the force in rope 1.: The tension in the two vertical ropes must sum to 700N in order to balance the window washer. EDIT. In order to find the answer for each rope, I need to know how long the scaffold is and where the window washer is standing. EDIT. Taking moments about the end nearest to window washer. T1*3.044 = 298.6*1.522 + 700*1.51 ----> T1 = 496.54 N (2. d. p.) Taking moments about the other end. T2*3.044 = 298.6*1.522 + 700*1.534 ----> T2 = 502.06 N (2. d. p.) T1 + T2 = 496.54 + 502.06 = 998.6 = 700 + 298.6 as required.

Q:A 520 kg box sits 1.4 m from the left end. What is the tension in the right hand side wire? (g = 9.8 m/s2) ____________ Newtons: Because the scaffold is not moving, we can assume that the net Torque acting on the scaffold equals zero. Net Torque = 0 torque = Force x distance (d) Use the left end of the scaffold as the center point. This will eliminate the Torque caused by the left wire (d = 0, so torque = 0) There are now three forces creating torque on the scaffold. There is the weight (m x g) of the scaffold, at 3.5m from the left end. m1 x g x 3.5m There is the weight of the crate, located 1.4m from the left end: m2 x g x 1.4m These two torques are countered by the torque caused by the Tension (T) of the right wire, located 7m from the left side. T x 7m The sum of these torques is zero. (T x 7m) - (m1 x g x 3.5m) - (m2 x g x 1.4m) = zero solve for T T = ((m1 x g x 3.5m) + (m2 x g x 1.4m)) / 7m T = ((115kg x 9.8m/s^2 x 3.5m) + (520kg x 9.8m/s^2 x 1.4m)) = 1.58 x 10^3 N Hope this helps.

Q:Disc scaffolding and bowl buckle scaffolding which kind of bridge support better?: 3 products have a high degree of economic, the use of more convenient and efficient in use, only need to put the plug into the hole of the ends of the cross rod pole corresponding, and then knock tightly, the quality of the demolition ride fast and overlapping is the traditional scaffold cannot do. Its erection speed is 4-8 times more than 2 times that of steel pipe scaffold. Reduce labor time and labor remuneration, reduce shipping costs to reduce the overall. The joint is reasonable in structure, easy in operation, light and handy. Vertical rod weight than the same length of the size of the bowl buckle 6-9%.

Q:What are the requirements for the sampling inspection of scaffolding?: 1 the sampling proportion of various structural parts shall not be less than 5% and not less than 20 pieces, and the quality shall comply with the relevant standards and regulations. Not meet the quality requirements of the structural parts shall not be used.2 wall thickness of steel pipe should be in line with the provisions of the special construction program, and shall not be less than 2.8mm, the wall thickness of less than 2.8mm of the steel pipe shall not be used;3 is strictly prohibited the use of cracks, deformation of the fastener, the bolt appears to be replaced silk;4 foot hand frame accessories must be used before the anti-corrosion treatment.
