Q:Scaffolding installation process, construction preparation
Construction preparation(1): steel pipe should be consistent with current national standard "carbon structural steel" (GB/T700) regulations Q235- grade steel; new steel pipe should be the product quality certificate; steel surface should be flat and smooth, no cracks, scarring, delamination, dislocation, bend, burr, indentation and scratch depth, pipe diameter deviation not more than -0.5mm, the wall thickness deviation not greater than -0.5mm, cutting slope deviation not greater than 1.7mm, the steel surface should be brushed with antirust paint; old steel corrosion depth not greater than 0.5mm, more than the prescribed steel shall not be used.(2): buckle made of malleable iron fasteners, the material should be consistent with current national standard "steel pipe scaffolding fasteners" (GB15831) regulations; old buckle inspect before use, shall not have cracks, deformation, bolt appear smooth silk must be replaced; new and old fastener must brush good antirust paint.(3) foot board: the use of 4m long wooden foot board; foot width of not less than 200mm, the thickness is not less than 50mm, both ends should be set with a diameter of 4mm galvanized steel hoop two; rotten feet can not be used.(4) safety net, paint.(5) after the inspection and acceptance of the above parts have been classified and piled up in a neat and orderly manner, no water can be accumulated.2, scaffolding erection and removal(1) scaffold erection
Q:Little help on Industrial/Scaffold Piercings?
okay, if you do end up getting it, make sure you get it on the side you DONT sleep on. dont let shampoo get on it. be really careful with it. if you have longer hair dont let your hair get caught in it cause it'll get tangled on it and it'll hurt and tug on the bar. it's usually around 40 dollars for it. this piercing requires a long time to heal and it has a high risk of infection. but if you take good care of it, you'll be good (: hope this helpedd.
Q:Standard for inspection of portal scaffolding
The 1.2 Standard Specification for steel portal frame and accessories: vertical rod and the transverse diameter: 42.7 + 0.5 mm with an average of 42.9 with a wall thickness of 2.5 + 0.3 mm with an average of 2.45 cross brace: outer diameter of 25 + 0.5 mm with an average of 25.4 with a wall thickness of 2 + 0.3 mm average for 2.3 1.3 door frame and accessories the steel pipe and plate, the welding meets the conditions, allowing the use of the mechanical properties of Q235 steel are made of Q235 steel or better material; when using the tensile strength and yield strength of Q195 steel is low, without affecting the connection and construction conditions, allows for increasing the thickness of the way to make up for the strength the lack of.
Q:Bracket cast in situ beam bracket must use bowl buckle scaffold
No mandatory provisions.JGJ1622008 construction formwork safety technical specifications, is the latest specification
Q:What is the difference between Scaffolding and Zone of Proximal Development?
Taken from okorder: Vygotsky believed that when a student is at the zone of proximal development for a particular task, providing the appropriate assistance (scaffolding) will give the student enough of a boost to achieve the task. Once the student, with the benefit of scaffolding, masters the task, the scaffolding can then be removed and the student will then be able to complete the task again on his own.
Q:As Hester once did, what time of day did Dimmesdale attend the Scaffold, and what compels his action?
Haven't read this book in years but I believe he goes back to the scaffold at night because he is being eaten away by guilt. It is a type of redemptive action, just as Hester had to stand there and be judged for her sins he feels the need to also stand there on the scaffold with Hester (theoretically) and be judged/punished as well, the only difference, of course, is that he does it under the cloak of night, when no one can see him.
Q:what happened when author dimmesdale went to the scaffolding in town square?
Which time? The first time he went there at night, admits his sin, mets up with Hester Prynne and Pearl, and an A appears in the sky. The second time, Arthur Dimmesdale reveals this secret to the public. He then has a heart attack on the scaffold and dies.
Q:How badly does getting an industrial/scaffolding piercing hurt?
My lip piercing did not harm in any respect. i've got not got an anti-tragus piercing, yet I do have a ordinary tragus piercing and that harm even under the lip. To be elementary, they are the two very tolerable. My navel piercing harm better than the two one in each of them.
Q:Does a scaffolding piercing hurt?
You sound like you have a low tolerance for pain if you say you're a wimp haha, which means yeah it'll probably hurt you. It'll hurt more than the lobes because it's cartilage, and for the same reason you'll hear a popping noise as the hole is made. You won't be taken over by deathly pain or anything like that, it'll probably be sensitive for a few days after too so careful not to knock it against anyone/ anything. But if you want it bad enough, the pain will be bearable.
