    Along with social progress and the industry continues to move forward, from traditional hand masonry floor gradually industrialization, standardization of assembly. From the first, the second generation, to the third generation of development.

    The first generation of floor ── situ concrete formwork floor boards
    The first generation of slab formwork ── situ reinforced concrete slabs, suitable for low-level and multi-reinforced concrete. The floor to be used in steel house, faced with the following challenges:
    1. The floor needs more cumbersome construction scaffolding, laying the template, tie bars and other manual jobs, their employment capacity, construction of low efficiency, long construction period, the quality of instability, it is difficult to adapt to steel Quick construction characteristics and requirements;
    2. The construction process must be layer by layer construction, while construction cannot meet the requirements for high level steel building;
    3. The relevant specifications must meet the grade of concrete strength after 75% -100% before form removal, usually concrete curing cycle takes 9-15 days, after which the next layer before construction. For high-rise, high-rise steel construction project in terms of slowdown, the idling time is too long.

    The second-generation floor ── combination situ concrete steel sheeting deck
    To meet the fast characteristics of steel construction, the second generation of the floor decks came into being ── with ribbed high pressure plate (thickness 0.75-1.5mm) instead of the template. This floor system minus the scaffolding process and support template process more efficient than the first generation of floor construction has been greatly improved which can be widely used in public buildings. However, the floor will be applied to steel houses, still facing great challenges:
    1. Steel banding process still needs to be done manually at site, which is still a large amount of work;
    2. The pressure plate force participation as a permanent template cannot be removed. Pressure plate fin height of 5-7cm mostly steel, and residential projects due process high level roofing limit cannot do, thus it is difficult to accept this floor deck by the tenants.

    The third generation of a floor slab of reinforced concrete composite truss Cast
    To meet the development of steel housing, the urgent need to seek and steel "high, big, light, strong, and fast" phase matching, to meet the requirements of residential comfort solutions ── floor without scaffolding And formwork, steel banding significantly reduce the amount of on-site and, ultimately, the bottom of the in-situ concrete floor effect equivalent level, to meet the "factory production and assembly of the construction" industry requirements, reduce site work capacity and increase the new floor deck system construction quality and efficiency. Thus, digestion and absorption of first-generation, second-generation floor advantages and disadvantages of the third generation of floor ── steel truss floor decks come into being.

     
     
    Advantages of rebar truss deck industrialization:
    1. The rebar truss floor deck is a kind of combined floor cover. When under construction, the deck is capable of certain construction loads similar to its self-weight; when under application, the rebar truss is integrated with the concrete body by its upper and lower strings of rebar to bear the working bearing together.
    2. The rebar truss deck system thoroughly changes the traditional manual working methods. By industrialized and mass production and pre-fabrication construction, the wooden formworks are barely used, which also slowdown the environment pressure;
    3. 80% of the site rebar working quantity is cut, and 60% of the site working quantity is also cut, which would solve the potential 'lack of labor ' problem;
    4. The construction period is shortened by 30%, and thus the construction quality will be reliable and guaranteed, practically improve the innovation our country's construction technology.
     
     
    Economic
    1.Steel truss force mode, economic selections, and comprehensive cost advantage are obvious;
    2.The steel truss height and diameter can be adjusted when applied to a larger span floor deck;
    3.Wire provides rigidity to the construction stage, reducing the amount of steel and the relevant costs.
       
    Convenience
    1.70% of the site rebar banding quantity is cut;
    2.No need of the scaffolding and formwork processes;
    3.Simultaneous construction at different floors, 3D cross operation with different workers, shorten the working period at large.
       
    Safety
    1.Mechanical properties superior to traditional roofing board, with good crack resistance of the floor deck;
    2.Fire resistance similar to that of the traditional ones, superior to pressure plate combination floor deck;
    3.Bottom mold is not involved in the working stage for the stressing, so no need to worry about corrosion problems.
       
    Reliability
    1.Factories standardized production with steel arranged uniformly, precise size, distance between the upper and lower steel and concrete cover thickness reliable assurance;
    2.Floor bidirectional stiffness similar advantageous to improve building seismic performance;
    3.Stud welding quality assurance easier to avoid the destruction of galvanized steel corrosion layer is profiled steel plate for cored welding.
