FAQ

Who knows how much the amount of the main material used to take one square metre of conventional double row scaffolding (within 12 meters). For example, how many kilograms of steel pipe, the number of fasteners. The content of the quota is low, I am also very confused, to the completion of the work of the scaffolding rental fees. Very urgent, I hope to know the user to answer. Accident report

What are the dangers of scaffolding
(5) the improper operation of the accident collision accident, etc.)Analysis of the main reasons two accidents:1) whole frame dumping, vertical collapse or local collapse frameStructural defects: the structure of the lack of the necessary structural members, not in accordance with the provisions of the number and requirements of the erection of the wall, etc.;In the process of using the arbitrary demolition essential bars and even wall pieces etc.;
A scaffold is constructed by placing two supports under a 13 ft, 9 in (a) board weighing 84 lbs. The supports are each 2 ft, 8 in (b) from their respective ends. Two painters stand on the board; one weighs 158 lbs and stands 4 ft, 11 in (c) from the left end of the board. Where must the 222 lbs painter stand so that each support carries the same weight? (express your distance in feet from the right end of the board (d).)please help!! thanks(:
Total weight = 222 + 158 + 84 = 464 lb So, each support must carry 232 lbs Working in inches: Take moment about Right hand end Board is assumed to be uniform - CG is at the center (232 x 32) + (232 x 133) = (158 x 106) + ( 84 x 82.5 ) +(222 x d)7424 + 30856 = 16748 + 6930 + 222d 222d = 14602 d = 65.77 inches Distance of 222 lb painter should be 5ft 5.77inches from Right end
Please help me in building professional people (scaffolding)
Door type scaffolding when used in general decoration, that thing is a direct product, a simple spell on the line, who rent who fightBowl buckle scaffold is also finished steel pipe, but there is no fastener, his fastener is a kind of fixed in the steel pipe instead of the demolition of the scaffolding is more convenient than ordinaryRent depends on the specific market
Specific requirements, the civil code is what ah! Thank you very much, I am lack of this kind of information, I hope you can tell me which of the following
Inspection and acceptance1) the relevant provisions on inspection of steel pipesSteel pipes, fasteners, safety nets and other products must have a certificate of quality.All components must have quality inspection report, steel material inspection method must comply with the national standard "metal tensile test method" (GB/T228) the relevant provisions of the quality should be consistent with the "carbon structural steel" (GB/T700) regulations Q235. a steel.The surface of the steel pipe shall be smooth and free of cracks, scars, delamination, dislocation, hard bending, burrs, indentation and deep scratches.The outer diameter of steel pipe 48mm allowable deviation is 0.5mm; the thickness of the wall 3.5mm allowable deviation of.0.5mm; steel pipe surface cutting oblique deviation 1.7mm;
What does Scaffolding mean in the educational talk?
It refers to the ways that you break a concept and/or a task down using graphic organizers, etc.
In the calculation of the bearing capacity of the scaffold, what is the axial force produced by the "N g2k" - the standard value of the component?The calculation formula for force rod scaffold N/ psi A+Mw/W = fWhere N=1.2 (Ng1k+Ng2k) +0.85*1.4 Sigma NqkThe specification of N g2k is explained in terms of the axial force generated by the standard values of the component fitting,It is how to understand, specifically refers to what? That is to say, what is the standard value of the component?Please master all trouble, thank you generous with your criticism!
Hello friends, NG2K said the weight of the standard parts of the standard value of the axial forceNG2K (kN) formula: NG2K = NG2+NG3+NG4 = 3.094 kN; NG2 and NG3, respectively, NG4(2) scaffolding deadweight standard value (kN/m2); the bamboo scaffold board, the standard value of 0.30NG2= 0.300 x 7 x 1.500 x (1.050+0.3) /2 = kN = 2.126;
improper design of formwork and scaffolding, not adequate braces and supports, improper handling, corrosion of material is several factor of formwork and scaffolding failure. it is estimated that more than 3000 accidents involving falls from scaffolds and 30 fatalities
Well, it seems you came close to answering your question. But are falls a scaffolding failure? For me failure means that the scaffolding sagged or fell - which may result in injuries with or without falling as when the failing scaffolding falls on a worker on the ground. I would think that major causes of failure as I defined it would be inadequate or failed attachments to the building and failure of ground support for the structure. Question needs to be improved to define what you need in answer and avoid conflict between question and detail.
