The advantages and disadvantages of housing construction project: coupler scaffold
The advantages and disadvantages of housing construction project: coupler scaffold
1, the advantages
1) the bearing capacity is bigger. When scaffold geometry and structure meet the requirements of the specification, under normal circumstances, the scaffolding of the bearing capacity of single pipe column can reach 15 kn ~ 35 kn (1.5 ~ 3.5 tf, tf design values).
2) convenient installation and erection of flexible. Due to the length of steel tube is easy to adjust, fastener connection is simple, and can adapt to all kinds of plane, elevation of buildings and structures in the scaffold.
3) to compare the economy. Simple processing, an investment cost is low. If carefully designed scaffold geometry size, pay attention to improve the steel pipe flow utilization rate, the dosage of material also can obtain good economic effect. Fastener steel pipe frame or steel used quantity of about 15 kg per square metre.
2 and disadvantages
1) fasteners (especially its screw) easy to lose.
2) node bar for eccentric connection, passed by sliding resistance load and internal force, and thus reduce its bearing capacity.
3) fasteners node connection quality is affected by fasteners itself operation quality and workers.
3, adaptability,
1) to build all kinds of scaffolding, templates, and other supporting frame.
2) assembly tic-tac-toe frame.
3) the erection and other temporary structures, ramp, barrack, stand
4) used as auxiliary of other kinds of scaffolding, strengthen the bar.
