The latest JGJ130-2011 construction fastener type steel pipe scaffolding safety technical specifications, schedule A.0.2 what role, how to correctly use it?
The steel section size of less than 48.3 x 3.6 mm diameter, scaffold structure weight per meter under par value, can also according to AppendixTable A A.0.2 calculation, the calculation results of partial safety, step distance, vertical distance and horizontal distance between values according to linear interpolation calculation.
Fastener type steel pipe scaffold composed of which components?
3.2 fasteners3.2.1 fasteners shall be made of malleable cast iron or cast steel, the quality and performance shall be in accordance with the current national standardRegulation of GB15831 for pipe scaffold fastener. Fasteners made of other materials shall be tested and verifiedQuality meets the requirements of this standard before use.3.2.2 fasteners in bolt tightening torque to 65N * m, shall not be damaged.
i have my nose pierced and am thinking about getting a scaffold cartilage piercing, but am affraid because your cartilage is so tough! and i know it depends on the person when it comes to pain, but just compairing it to a nose piercing? (when i got my nose pierced i cried, but once they finished piercing it, i wasn't in anymore pain)
ive just had scaffolding done, and it was quite painful, far more painful than i was told. they just stab through your ear with a needle, but i didn't think it was that bad. not as bad as getting your nose done. but it was very sore and painful to touch for days after. hope this helps :) X
How to calculate the fastener type steel pipe scaffold
1.1.2 provides for the temporary structure of the scaffolding structure, the structure of the importance coefficient of gamma 0 take 0.9. ?The scaffold structure design of 1.1.3 on reliability requirements, considering that there is no enough statistical data accumulated by the situation, determine the probability limit state design, should be consistent with our historical experience, if using a single coefficient method was designed, the single safety coefficient should be satisfied: the strength calculation of K1 = 1.5 the stability calculation; K2 = 2. To this end, in the calculation of the introduction of the material strength of the additional coefficient of gamma 'm' or resistance to the addition of partial coefficient gamma 'R, gamma' R= gamma 0 gamma 'm=0.9 gamma' m.

Can you do the outer scaffolding?
(2) the outer side of the scaffold must be provided with scissors, scissors width should not be less than 4 span, and should not be less than 6m, the angle between the diagonal rod and the ground is 45-60 degrees. The intersection points of the oblique bars are on the same straight line and are arranged along the height of the frame. (3) a diagonal rod of the scissors is buckled on the upright post, and the other inclined rod is buckled on the end of the small transverse rod, and the two ends are respectively fixed with a rotating fastener. All fixed pitch master node distance not greater than 15 cm
What are the chances of cracking the tile? What can I do to avoid cracking the tile?This will be 3 levels of scaffolding on 6 inch wheels.
unless you are majorly manhandling the scaffolding, such as slamming it around and jerking it into place, etc, you won't crack the tiles (this is being said with the hopes that the flooring was installed correctly.) i would throw a layer or two of bedsheets or a good heavy drop cloth over the tiled floor just to protect the tile from being chipped or scratched. be careful going up so high. good luck!
