Climbing and floor scaffolding advantages and disadvantages
Climbing frame, also known as lifting frame, according to its power source can be divided into hydraulic, electric, human hand pull and other major categories. But also has the structure of fixed shortcomings.
Climbing frame, also known as lifting frame, according to its power source can be divided into hydraulic, electric, human hand pull and other major categories. It is developed in recent years, a new scaffolding system, mainly used in high-rise shear wall real estate. It can climb up or down along the building. This system makes the scaffolding technology completely changed: one is not to turn the shelf; the second is to remove the scaffolding disassembly process (after assembly has been used to complete the construction), and not subject to height restrictions on the building, a great savings in manpower And material. And in the security point of view for the traditional scaffolding has a greater improvement. In the high-rise buildings with great development advantages.
The bolt tightening torque should not be less than 40N · m, and should not be greater than 65N · m; [1] 2) The bar at the node is eccentric, 3) The connection quality of the fastener joints is significantly affected by the quality of the fastener itself and the operation of the workers. (3) The connection quality of the fastener joints is significant.
Easy assembly and disassembly, erection flexible. As the length of the pipe is easy to adjust, fastener connection is simple, and thus can be adapted to a variety of flat, facade buildings and structures with scaffolding. More economical, simple processing, a low investment costs; if carefully designed scaffold geometry, pay attention to improve the use of steel pipe turnover, the amount of material can also achieve better economic results. Fastener steel pipe frame equivalent to about 15 kg per square meter of building steel.
Floor scaffolding: Advantages: bearing capacity. When the scaffolding geometry and construction in line with the relevant requirements, under normal circumstances, scaffolding single tube column bearing capacity of up to 15kN ~ 35kN (1.5tf ~ 3.5tf, design value).
