Steel bar truss girder is composite of corrugated sheet and steel bar truss which replace wooden template to bear all the construction loads in the construction phase and participate in bearing structure load in the service stage. Composite deck is floor deck which replace all or part of the force steel bar and work together with concrete in the service stage, while steel sheet of steel truss deck does not participate in bearing structure load, it's non-composite deck.
|Top and bottom bar diameter||6-12mm|
|Cross bar diameter||4-8mm|
|Decking thickness||Galvanized steel sheet 0.5mm|
|Application area||Multi-layer buildings|
| ||Slab of reinforced concrete structures|
| ||Precast reinforced concrete floor|
| ||Irregular buildings(rounded, oval, and other shapes)|
| ||Large span structure|
| ||Lower board structure|
| ||Thick board structure|
| ||Leaning roof|
| ||Housing steel structure|
|Advantages||Economy: The mode of truss is reasonable with low price and has an obvious advantage in this area; Can be designed as double-sides deck.|
| ||Convenience: Shorten the project construction time; Reduce temporary support.|
| ||Security: Good performance of cracking resistance and fire resistance;|
| ||Reliability: good property to prevent earthquake.|
SXGG steel bar truss floor deck is the integrated fabricated formwork for which steel bar is to be processed into steel bar truss and then the steel bar truss is to be welded with galvanized profiled sheet. In the construction stage, the steel bar truss floor deck can bear the construction load; moreover, concrete can be poured after steel bars are directly laid on the beam for simple steel bar works. As form functions can be completely replaced, form erection and removal works can be reduced, so floor slab construction efficiency can be greatly improved.
SXGG steel bar truss floor deck has features such as economy, convenience, safety and reliability, etc and it has been widely used by structure and building fields such as multilayer workshops, multilayer, high-rise and ultra-high steel structure buildings and various irregular floors, concrete structures and high speed railway, etc.
