I took 20 overhanging scaffolding difficult to take the highest. How many meters height
I-steel whether ordinary or light, because the section size are relatively high and narrow, so the moment of inertia of section two of the spindle is larger, so it only can be directly used in the web plane bending member or the composition of lattice stress components. It is not suitable for the axial compression member or the bent member perpendicular to the web plane, which has great limitations in its application.
I-beam is also called steel girder (English name Universal Beam). It is a strip of steel with an I-shaped section. I-beam is divided into ordinary I-beam and light I-beam, H steel three. It is a section steel whose shape is trough.
Cantilevered scaffold generally has two kinds: one kind is each layer of a pick, the vertical rod at the bottom of the top in the construction site, floor beam or wall, outward tilt after fixed on the upper part of the erection of scaffolding construction, rail laying layer, construction of a story, to be transferred to the upper layer, and then re ride scaffold provides a layer of construction; the other is the multilayer cantilever scaffold, the full height is divided into several sections, each section of the erection of a height of not more than 20m, the use of cantilever beam or cantilever frame for scaffold based subsection overhanging scaffolding section, this method can use scaffolding over 50m above.
I took 20 overhanging scaffolding difficult to take a maximum height of 20 meters.
