Steel truss deck No need stand, less reinforced Better anti-quake performance Better sound insulation Excellent fireperforma
At present, multistory and tall building usually take profiled steel sheet with some ribs -concrete composite floor,which has the disadvantages of high thickness, reducing inner height of building, unflattening of under floor, lots of reinforcement binding, hard control of distances between ribs and thickness of concrete.
To solve these problems, we research and develop the Third Generation profiled steel products-Steel Truss Deck.
Theory:
Truss deck is a kind of standardized product. It takes reinforcements to process into steel truss and then welded the steel truss and galvanized profiled steel sheets together. This system combine concrete with construction templates together to form a load bearing element to bear the weight and concrete and construction load and work as lateral strut of beams in construction. In the use phase, steel truss and concrete work together and bear the load.
Applications:
Using concrete floor decks, setting and discharging the templates can be saved. This kind of floor decks are not only widely used in different floor systems ,such as multistory and tall building, reinforced concrete structural floor deck, prefabricated reinforced concrete floor, but also in the irregular floor (round, oval-shaped and other shapes)structures, large-span structure, thick plate structure, pitched roofs, residential structure and other building. This system can increase efficiency and low cost.
Performances:
Comparing with other products, the truss decks have the following advantages:
No need of stand, less reinforced
Providing more working platforms, and constructing in a few floors at the same
Utilization of bottom formworks can reach 95%
Lowering the height of building, reducing the weight, saving cost
Be designed to decks loaded in two directions
Thickness of reinforced coating can be ensured.
Reducing crack width, improving floor performances
Better anti-quake performance
Better sound insulation
Excellent fire resistance
No need of anticorrosion treatment
Be beneficial to environmental protection
