Steel bar truss girder is the combination of steel bars and galvanized sheets,which is one composite decking sheet.In the use-phase,steel bar truss floor decking sheets is working together with concrete,and bear the loading capacity.
As the third generation of steel decking sheets,besides the advantage of previous floor decking sheets,it also has advanced technology and good performance on fast installation,anti-seismic,fireproof and anticorrosion.At the same time,there are many advantages,like stable quality,safety,neat panels,aesthetic environmental protection,economical material,low comprehensive cost,and rich panel type,etc.
1,Reliable fire resistance:
All the steel bars are covered by concrete,the fire resistance is the same as common floor decking sheets.The experimental results show that if the floor thickness is 100mm(truss height is 70mm),the fireproof hour limit is 1.68h.
2,No need preservative treatment:
The steel bar truss floor decking sheets used galvanized steel sheet,which is having anticorrosion function,but the bottom piece doesn't instead of steel bars' effects,so no need to do preservative treatment.
3,Easy and convenient installation:
This composite floor decking sheets is light weight,which make the installation very easy and convenient.This one could save a lot of labor force and improve the installation condition.
4,Save electric energy:
The bottom piece of steel girder is only 0.5mm thick,it greatly reduces power consumption,when welding the studs at site.
5,Benefit to environmental protection:
When construction reach the design strength,the steel plate on bottom could be dismantled and recycled.It could satisfied the residential steel structure floor slab bottom look and feel,also benefit to environmental protection.
1,Applied to precast slabs, pre-high-speed railway sleeper
2,Used in many high-rise, multi-storey steel buildings
3,Used for steel building, mezzanine floor of “LOFT”
4,The force applied to the complex, special-shaped structure, building
5,Used in-situ concrete structure(RC) buildings
6,Used in the construction of slope roof structure
What security measures do we need to pay attention to,when steel girder construction at site?
