DUOWEI 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.

DUOWEI 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.

1. Unique double folding design
Effectively increase board edge strength; hard to bend or deform during transportation and construction;
Ensure edge straightness of product, fastening of bottom form gets easier;
Improve compactness of bottom form lapping, effectively prevent leakage;
Improve construction quality and protect customer’s interests.

2. Improved form spot welding technology
Original form spot welding equipments are improved to make welding current of many welding heads more balanced and stable, so the floor deck to be made will be free from cold joint or weld penetration phenomenon.

Four advantages

Economic
The load-bearing mode of the truss is reasonable, the consumed materials economic, and the advantage of integrated costs obvious.
It can be designed into two-way slab, with adjustable truss height and diameter of reinforcement, intended to apply to the floor slab of larger span.

Convenient
The field steel binding quantity is reduced by 60% - 70%, and the construction period is further shortened.
The load-bearing mode of the truss is reasonable, which can provide greater stiffness to floor beating slab, greatly reducing or even sparing the use of temporary bracing.

Safe
The mechanical property is basically the same as the traditional floor slab, with good crack resistance.
The fire-resistant performance is equal to the traditional floor slab, superior to the profiled steel plate composite slab.
The bottom die is not loaded in the use phase, eliminating the consideration to fire and corrosion problems.

Reliable
The reinforcements are arranged uniformly, and the spacing between two layers of reinforcements and the thickness of concrete cover are reliably guaranteed.
The two-way stiffnesses of the floor slabs are similar, conducive to the seismic stud welding, so the quality is easier to ensure.
