Q:What are the requirements for acceptance of external scaffolding? Want to know before
7, scaffolding erection should be higher than the top of the building or the operating surface of 1.5m or more, and add enclosure. 8, the erection of the scaffolding on the steel pipe, fasteners, foot board and connection points shall not be arbitrarily removed. When necessary, the construction site must be approved by the person in charge of the site and take effective measures. 9, the use of scaffolding, the site should be responsible for the organization of inspection and acceptance, acceptance and fill in the inspection form before use. In the construction process should be professional management, inspection and warranty, and periodic settlement observation, found abnormal should take timely reinforcement measures.
Q:Cantilever beam type scaffolding can not exceed the maximum number of not married
An overhanging canopy should be the pillars of the non overhanging balcony canopy may be concave balcony, may also be the pillars of support (pretty much before the home house) pick style balcony canopy should be the cantilevered balcony canopy is not that direct pick out in the post
Q:Method for inspection of foot hand frame fittings
Should adopt the current national standard "straight welded steel pipe" GBT 13793
Q:How long after getting an industrial/scaffold ear piercing does it stop hurting?
When I got my ears pierced professionally, they only hurt for a couple days, maybe a week if I messed with them too much. Later, I personally double pierced my earlobes with a sterile needle at home, it's been over a month and it still occasionally hurts when I sleep on it weird. That is my experience, however it depends if they use a gun or a needle, where exactly you have it pierced, and other factors still can change (infections) the amount of healing time. But a good ballpark figure is about 1-2 weeks, but I know people who's pain can last a month. Good luck, and make sure you find a good professional piercer, and not the local mall free piercing preteen shops :).
Q:What's an antonym for the word scaffold?
Since a scaffold is a bridge/ladder/support used to allow you to span the gap between you and and object you wish to reach, I'd go with barrier.
Q:Scaffolding scaffolding erection norms which requirements, who can say?
Scaffolding operators must be qualified through the examination of professional personnel, should be held on the card and do a regular physical examination, the operator must wear a helmet, fasten the seat belt, wear non slipIn the process of using frame control load less than ZkN/mZ2kN/ square meters, the prohibition of arbitrary demolition wall connecting rod and other safety facilitiesEach component and frame tube of the cantilever frame must be transmitted to the ground in timeWhen the shelf is removed, a fence or warning sign should be set up around it, and someone should be assigned to guard itFasteners and steel pipe diameter matching use, and the factory certificate. It is found that there is crack, deformation, the prohibition of the use of silkThe erection of temporary power lines and the grounding of the suspension frame and the lightning protection measures shall be carried out according to the national standards
Q:What are the safety requirements for the dismantling of construction scaffolding
(1) prior to the dismantling of the scaffold, the work instructions for the removal shall be prepared and submitted for approval according to the design approval procedure of the scaffold. No work instructions or safety measures are not implemented, it is strictly prohibited to dismantle the work.(2) prior to the removal of the work, the approved work instructions and construction plans shall be made to the site construction personnel. And should check the implementation of site safety measures.
Q:Can a person get electrocuted if he's holding an exposed wire in one hand and metal scaffolding in the other?
I'll assume you mean a LIVE wire, AC. 1. If there is no connection to ground at all, NO. Birds can sit on live wires. 2. The current will flow from wire through body and scaffold to ground, then from ground through scaffold and body to wire, reversing at a rate of 60 times per second (America). Depending on the voltage on the wire, that person will most likely die or even be burned apart.
Q:When scaffolding is erected on the base of the permanent structural concrete
. Among them, the specification of the steel pipe is from 0.5m to 6m, and the fastener mainly has a rotating shaft, a cross and a joint fastener. Bowl buckle scaffold also uses Phi 48, 3.5 wall thickness steel
Q:Can I recycle steel scaffolding tubes by encasing them in concrete to make a stronger beam.?
You can, but I can think of two reasons why it might be unwise. Firstly, reinforcing bars are ribbed to provide a key between the concrete and the steel, whereas scaffolding bars are much smoother. This leads me to believe that scaffolding bars, weight for weight, wouldn't be as effective as reinforcement bars and you wouldn't have as much reinforcing action as you think. In extremis, you could end up with an under-reinforced concrete beam which will be brittle - reinforced concrete is usually deliberately slightly over-reinforced so that the behaviour close to failure is ductile, as it gives you time to run away. Secondly, scaffolding bars are hollow and reinforcement bars are solid. In reinforced concrete, the alkalinity of the cement paste helps to protect the reinforcement from corrosion - the reason for specifying a minimum cover - but the inside of your scaffolding bars would not benefit from this and so I'd worry about the risk of shortened life due to rusting from the inner face. At least when reinforcement bars rust they tends to spall the concrete cover off, which you see happening.
