Steel truss decking is a composite combination of girder and decking. The girder is made in mass in the factory. Girders made by steel bars, bear loading in construction operation and decking support the wet concrete. By this technique, form erecting work and costs are avoided.
Top and bottom bar adopt hot-rolled steel bar in coils Grade HPB235, HRB400 or cold-rolled ribbed steel bar Grade 550. Brace bar adopt cold-rolled steel bar Grade 550 or 650, support bar adopt hot-rolled steel bar Grade HPB235 or HRB335. The additional hot-rolled steel bar used in the building floor apply Grade HPB235, HRB335 HRB400or Grade 550 bar.
Use profiled steel sheet as decking. The steel sheet adopts galvanized steel sheet or other kind of thin sheet, a thickness of 0.5 mm and tensile strength not lower than 260 N per square millimeter. Zinc coat in both sides of galvanized steel sheet are totally not less than 120g/m2, and quality standard should coincide with the relevant quality requirements.
Use cold steel sheet as decking. Decking thickness is 0.4 mm and quality should accord with the relevant quality requirements.
At the construction site, put truss decking on the steel beam, and bind the connecting longitudinal bar between girders, support additional bar and scattered bars. After pouring concrete, concrete floor is formed. Cross section refers to 3.1.1 and 3.1.2.
Applicable for ordinary industrial and civil building floors, roof, operation platform, surface of viaduct and etc.
