Q:What is the difference between Scaffolding and Zone of Proximal Development?
Zpd And Scaffolding
Q:How many meters per square meter and the number of steel fasteners
According to the height of their own construction plans, according to the construction area of 1 square root, fasteners ranging from docking fasteners and rotating fasteners, rotating fasteners should be every square of the 3 bar, a detailed look at the old construction workers
Q:What would go good with my Scaffold/Industrial piercing?
conch would look great and not make it look to cluttered go for it :)

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 scaffold spanners used for?
Ratchet Podger Spanners...Aluminium Scaff Spanners Spanners are wide wrenches that are made from durable metals. Spanners are made specifically for scaffolding and are designed to fit into the tool belt nicely. Spanners are very useful for a number of jobs and are often used along with other scaffold tools on a safety lanyard to prevent dropping the tool to the street below. Spanners work the same as traditional wrenches but like many scaffolding tools are made with a hole in the end of the wrench for the safety strap to be inserted through. Stainless steel and aluminum are the most commonly used metals for spanners to ensure durability even if the item is dropped from high.

Q:In the construction of steel pipe scaffolding steel pipe and steel stamping fastener usage ratio is how much?
Generally 200 tons of steel pipe with fasteners, and fasteners are generally divided into three kinds: right angle fasteners, connecting fasteners, rotating fasteners
