Circulation of the current rental market construction and building materials, mainly steel pipe fastener scaffold, accounted for more than the entire formwork scaffold turnover, due to domestic regulation unit and material related defects, lead to a lot of unqualified products in the market circulation, at the same time it also happens a lot of the tragedy of the dead. 

Ringlock scaffold under the background of the current, get more and more the welcome of the customers, and even in some areas specially introduced about ringlock scaffold mandatory promotion policies to guide the construction unit sourcing direction. But because the ringlock scaffold use less, state and market is not a clear definition of the scaffolding system, lead to many customers don't know how to choose to appear.

In fact, ringlock scaffold meaning is very wide, ringlock type fastener tighten, the steel pipe scaffold difference between its definition because on stud welding groove, undertake hole, on a rod welding plugs, through the slot of the jack and plug to tighten. According to this way of naming, ringlock scaffold contains: cuplock scaffold, dovetail groove type scaffolding, scaffold, wheel scaffold, ringlock type of scaffolding, etc. Cuplock scaffold components are heavy, large dosage, installation requires four directions of tie rod after installation can close up and cuplock, so operation is not very convenient.

This kind of product, but in the actual use process, because of the large area laying, scaffolding poling placed slightly deviation will not be able to put the bar slot, the workers want a high quality and operational level, therefore no popularity. Ringlock type is a begin to stage the erection activities abroad, later research gradually used in bridge viaduct project, instead of a ringlock, with security, stability, steel quantity is little, the characteristics of low cost unit square meters, now has gradually been accepted by China railway, the intersection of corporation and promote the use.
