Fabricated steel truss floor plate with free bottom die

      The prefabricated steel truss floor bearing plate is a new type of steel truss floor bearing plate which is made of steel truss and non-removable bottom mold by special connecting parts or anchoring prefabricated into a whole, and is produced in an industrial way. It has the function of formwork in the construction process without removing molds, and conforms to a new type of material for prefabricated buildings.

Truss floor plate composition

Bottom plate— The bottom plate acts as the permanent mold shell of the floor and collaborates with the trusses or bending ribs of the combined formwork. It acts as the working platform during the construction stage and becomes the surface of the floor after the floor is poured. The bottom plate material should be the plate material made by mechanical embedment of galvanized steel plate with thickness greater than 0.4mm in the board making stage.
Steel truss — The steel truss bottom plate is welded by the embedded steel shell plate to form a composite formwork. The steel truss participates in the stress of the floor structure, and has the structure of on-site laying interspersed structural steel bars and pipelines. Together with additional steel bars and superimposed layers of concrete, it can form an integral single and bidirectional bending floor member.
join— The bottom plate and steel truss are connected by welding, and the connection points are arranged with equal spacing. The welding spacing should be 200~400mm according to the load. The limit value of tensile strength of each connection point should be greater than 1.0kN, and the limit value of shear strength of each connection point should be greater than 1.7kN.

Product characteristics

1. An important member of prefabricated building —According to the relevant provisions of the national standard "Evaluation Standards for prefabricated Buildings" GB/T51129-2017, the prefabricated steel truss floor plate without removing the bottom die can be
Prefabricated buildings score 10 to 20 points.
2. Independent research and development, independent intellectual property rights —It has authorized 9 utility model patents and 2 appearance patents.
3. Industrial production, assembly construction, reliable products, reliable construction —Convert on-site manual work into factory equipment processing, reduce human uncontrollable factors, effective control of steel bar spacing and concrete protective layer thickness,
Meet the design requirements.
4. High output, fast construction, single line daily output, supply is guaranteed —The high degree of assembly reduces most of the work of steel binding and scaffolding erection; Reduce the time of large amount of material transfer on site.
5. Low cost —The bottom plate does not need to remove the mold, with decorative function, saving labor, materials, machinery, management costs, comprehensive cost savings of more than 20%.

Application field

The product has been recognized in the relevant affordable housing standardization, and has begun to be widely used in commercial real estate, and has been praised by relevant national departments, developers, design institutes and so on. Especially applied to pre-cast reinforced concrete frame structure, shear wall structure, prefabricated concrete structure, steel structure, ZGM passive house structure, LOFT mezzanine, reinforcement and so on.

Prefabricated floor comparison

  • Normal
    Superimposed plate

    1, mature technology, manufacturers.
    2, floor design calculation is simple.

  • prestress
    Superimposed plate

    1, compared with ordinary laminated board weight is small, lifting, transportation efficiency is improved.
    2, the floor stiffness is large, more difficult to crack.
    3, suitable for large span space.

  • Metal bottom die rebar
    Truss floor plate

    1, mature technology, manufacturers。
    2, the processing speed is fast.
    3. Light weight, high lifting and transportation efficiency.
    4, the floor integrity is good.

  • Removable bottom die rebar
    Truss floor plate

    1, the processing speed is fast.
    2, the floor integrity is good.

  • No removal of bottom die reinforcement
    Truss floor plate

    1, the processing speed is fast.
    2. Light weight, high lifting and transportation efficiency.
    3. The flatness of the plate bottom after forming is high, and the decoration is convenient in the later stage.
    4, the floor integrity is good.

  • 1, the construction of the surrounding reinforcement is inconvenient, and the site still needs to be partially cast in situ.
    2, need maintenance before leaving the factory, long processing cycle.
    3, since heavy, hoisting, transportation efficiency is low.
    4, the floor integrity is poor.

  • 1, floor design calculation is complex.
    2, the processing process is complex.
    3, fewer manufacturers.

  • 1. Metal bottom film leads to later stage
    Decoration, decoration inconvenience.

  • 1. The floor molding is poor after multiple turnover of the bottom film.
    2. The removal of the bottom film is time-consuming and laborious.

  • 1, there are supporting production and construction technology,
    Supply chain resources are less.
