The rebar truss deck is a composite template which is welded into one combination by the steel truss and galvanized steel rolled-plate ,and the rebar truss is welded by rebar in the shop. In the construction phase ,the rebar truss deck can sustain the construction loads ,and be laid on the beam directly, then do some simple rebar work ,it can do the concrete work .the steel truss deck replaces the template without erection and demolition ,so improve the construction efficiency.
The Rebar truss deck is economic,convenient,safe,and reliable. At present ,it wildly used in the area of buildings such as multi storied factory,multi, tall and super tall steel buildings,various irregular floor,reinforced concrete structure and high-speed railway.
The advantages of Steel Bar Truss Floor Deck
1.1 Reasonable mechanical mode and economic materials: stiffness during construction stage is provided by the truss made by relatively cheaper material and steel bars in floor plate originally, which reduces the used amount of relatively more expensive material to the least. Therefore, the comprehensive cost advantage of floor plate is obvious.
1.2The height of truss and the diameter of steel bar can be adjusted to meet the requirement of greater plate span without support, thus greatly reducing supporting workload and man-power.
1.3The truss floor plate can be designed as bidirectional plate which has competitive economic advantages compared with profiled sheet.
2.1The amount of steel bar binding can reduce to 60-70%, further shortening construction period.
2.2Large plate span without supporting can provide multiple construction surfaces, at the same time reducing or without the need of temporary support for construction.
3.1Mechanical property is the same with traditional cast-in-situ and better than that of profiled sheet composite floor plate.
3.2Fire resistance performance is the same with traditional cast-in-situ and better than that of profiled sheet composite floor plate.
3.3 As bottom die is not under stress, it is no need to consider anticorrosive issues. The durability of floor plate is better than that of profiled sheet composite floor plate.
4.1Spacing of steel bar and thickness of protective layer are guaranteed by mechanized equipment, fully meeting design requirements.
4.2Double-folding and edge-locking overlap joint design effectively guarantees construction quality of floor plate.
4.3Bidirectional stiffness of floor plate is similar, meeting the assumptions of structural calculation, which is conducive to earthquake resistance of buildings.
4.4With 0.5 mm of penetration of stud and 120 g/m2 of galvanization, the welding quality of bottom die can be guaranteed.

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.
