Q:The latest JGJ130-2011 construction fastener type steel pipe scaffolding safety technical specifications
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.
Q:Topic?Scaffolding construction program how to doSpecial construction scheme
6, the vertical bar is arranged, it is necessary to consider the distance between the horizontal bar. The general spacing should not be greater than 1.5 meters (through the calculation of the pressure bar instability spacing);7, pay attention to the level of the rod near the ground and the top of the surface must have a rod (some people do not think this is necessary, but often up and down instability is difficult to insurance);8, the longitudinal brace configuration, with full support from top to bottom bracing will cross 45 degrees continuous configuration, intermediate cannot disconnect (i.e. a brace from the top to the ground, the middle long); brace configuration based on experience, but also can be calculated (using coplanar force system, theoretical mechanics learned);9, lateral bracing configuration, the same as the vertical;10, considering the load loading calculation of concrete three days is enough, if the concrete two times, loading unnecessary all add up, because the first pouring concrete general solidification, not the calculation of the load, favorable.
Q:What are the main safety problems when dismantling the scaffold
3, the demolition of spare parts to be loaded into the container, with a crane hanging; the steel pipe to be tied to secure, double point lifting, prohibited from high altitude thrown.4, more than six wind (including level six) to stop the construction of mobile scaffolding.
Q:when do i change my scaffold piercing?
Hi :) You can change it after 4 months usually But sometimes it can take up to a year It depends on the person , everybody's body heals differently You should go back to your piercer and ask if it's healed enough to change the jewellery Yep , it's normal A scaffold piercing goes through the cartilage and cartilage piercings can take up to a year to fully heal :)
Q:Cantilever scaffold technical disclosure Find satisfaction free speed!!!
Foot plate:(1) scaffold with welded steel sheet with 18# wire fence, bundled in the bar.(2) steel bar appear off, the serious corrosion of the prohibition of the use of.(3) the wire binding must use 18# wire binding, and each steel bar binding plate must be above 4
Q:Hoisting a scaffold: newton's second law tension problem?
The force felt by the person pulling is the same as the force in the rope between the two pulleys. It doesn't matter if the person is pulling straight up (without the pulley) or straight down(with the pulley) it's the same. Therefore the weight/force is divided equally between the two ropes.
Q:How badly does getting an industrial/scaffolding piercing hurt?
well when i got mine it really didn't hurt tht muchh the second hole hurt the most but only because i was thinking about it. andd it hurts more afterwards especially during the first few dayss if you hit it by accidentt. and cleaning it honestly is a pain, its annoyinggg but you have to do it, during the first few weeks clean it 3 times daily then you can start going down to two times daily. and do sea salt soaks and stufff anddd the actual piercing for me was about a 4 or a 5 (10 being painfulest) and the healing has been about a 5 or a 6 but i just got it done last weeek, if you really want it then get it,the pain is only temporaryy buttt its deff worth it in the end :)
Q:I want to know the classification of scaffolding in the building
Steel tubular scaffold. As to the steel pipe, and combined with other type of steel pieces composed of scaffolding, such as the channel has a base in the backwater or scaffolding, connecting steel scaffolding and so on. ScaffoldingBowl buckle steel pipe scaffolding when using steel pipe, as a "single steel pipe scaffolding"; when using the steel cross bar, for the "steel pipe based scaffold".
Q:What does scaffold one's days mean? kill time?
In 60 years of using English in Britain I have not come across that expression, so it is probably rare. Scaffolding is put up to help build or repair tall buildings, so possibly that expression means 'to do something useful with one's time.' But a scaffold is also, historically, a place of execution (legal killing of prisoner), so the expression could mean indeed 'wasting time'. I have a faint feeling that 'scaffold one's days' was written by a non-native speaker of British English. It may be more common in the USA.
Q:Does a scaffolding piercing hurt?
Depends on your pain tolerance, it's different for everyone. But generally cartilage piercings feel nothing like getting piercings stretched.
