1. Has the versatility, according to the requirements of the concrete construction, form different group size, shape and bearing capacity of single and double row scaffolding planks, racks, columns and other functions of construction equipment.

2. With high efficacy: simple structure, easy tear open outfit is simple, rapid, and completely avoid the bolt assignments and scattered fastener damage, joint speed of assembling and five times more than conventional block quickly down save labour, workers with a hammer to complete all assignments.

3. Has a large bearing capacity, vertical rod is connected with the axis of socket, node plane, the frame joint with bending, shear and torsion resistance performance, stable structure, bearing capacity is big.

4. Has a safe reliability: connector design considering the gravity, make joint have reliable two-way self-locking ability, load acting on the bar through the button to stud, button has a strong shear capacity of galvanized steel sheet (199 kn).

5. Packing of product standardization, less maintenance, fast loading and unloading, transportation is convenient, easy to store.

6. The service life of the button scaffold a lot higher than the fastener scaffold and generally can be used for more than 10 years, because of the abandoned bolt connection. Resistance components by touching upon. Even if rust does not affect the spell to use.

7. Early dismantling function: rail can remove the turnover ahead, save material, save wood square and save the human. Energy conservation, environmental protection and economic and practical.

8, Practice shows that the beam span within 15 m, headroom height under 12 m layer of single span, the multi-span continuous beam, frame structure building formwork support system, its good stability and safety in the cuplock scaffold, is superior to the scaffold.
