I. Overview of Steel Reinforced Truss Deck

　　                 Reinforced truss floor deck is a composite template formed by processing the reinforcing steel in the factory into a reinforced truss and welding it to a galvanized steel sheet bottom mold. During the construction phase, the reinforcing bars

                Joist deck girders can bear construction loads, be directly laid on beams, and simple steel reinforcement work allows for concrete pouring. As they completely replace the formwork function, they reduce the setup and dismantling of formwork frames.

                The process significantly enhances the efficiency of floor construction.A roof-decking product that enhances customer value,We have eliminated factors causing an increase in material costs.,Change the usage of the steel deck to only serve as a floor deck

               Templates at the construction stage, reducing the usage of corrugated steel sheets, and lowering the requirement for the stable coating performance of the corrugated steel sheets. We have altered the load-bearing mode of the roof deck during construction.,During the construction phase, by the molding

               Steel plate stiffness is now provided by reinforced truss, offering greater deck stiffness for larger unsupported floor spans. We have reduced the customers' post-purchase maintenance costs.,Pressure                 

               Sheet steel is only used as a formwork during the construction phase and does not require any treatment for performance stability. It is also not required to meet the lifespan requirements for building use, thus there is no need to consider the costs for future maintenance.

Section 2: Advantages of Steel Rebar Truss Decking

　　(1)Economic

Reinforcing truss has a rational load-bearing pattern, cost-effective materials selection, and obvious advantages in comprehensive construction cost.

Adjustable truss height and steel bar diameter for suitabilityetFor larger spans of floor

Can be designed as a double-sided board

　　 (2)Convenience

Field reinforcement binding work volume can be reduced60%-70%Further shortening of the construction period is achievable.

The truss loading pattern offers increased floor deck stiffness, significantly reducing or eliminating the need for temporary supports.

　　(3)Safety

Mechanical properties are essentially the same as traditional cast-in-place floor slabs, with excellent crack resistance in the floor.

Fire-resistant properties comparable to traditional cast-in-place floor slabs, superior to composite steel deck floor slabs

The bottom mold does not participate in the stress phase during use and does not require consideration of fire resistance and corrosion prevention issues.

　　(4)Reliable

Rebar is evenly arranged, with reliable guarantees for the spacing between layers of rebar and the thickness of the protective layer.

Double discount edge overlap design, effectively ensuring the construction quality of composite floor assembly.

　　Steel rebar truss deckSimilar bidirectional stiffness benefits seismic resistance in buildings.

Screw钉welding quality is easier to ensure.

Floor Decking Product Development History

     Three,TDV、TDMProduct Introduction: Steel I-Beam Truss Floor Deck

                TDV、TDMA type steel truss floor deck is a composite formwork that involves processing the steel reinforcement into a steel truss in the factory, then welding the steel truss with a galvanized corrugated steel bottom mold into a single integrated form.                    During the construction phase, steel truss deck can bear construction loads and be directly laid on beams, with only simple reinforcement work required for concrete pouring. As it completely replaces the formwork function, it reduces the board...           Erecting and dismantling projects, significantly enhancing the efficiency of floor construction.

       Section 7:TDMAdvantages of Type Steel I-Beam Truss Deck:

              Excellent weld joint load-bearing capacity

             "M"Type straight rib width up to2-3mmThe weld point bearing capacity of the steel bar web members of the steel truss is approximately equal to that of the ordinary"V"Type ribbed plate type weld joint load-bearing capacity1.5 Multiple.

              Excellent performance with stable results

              The distance from the steel truss to the welding point of the bottom form is approximately5mmThe bottom mold surface is free of weld points, preventing rust spots and demonstrating superior corrosion resistance.TDV Hot-rolled steel joist deck, eliminates the possibility of maintenance later.

              Avoid slippage

              Due to the absence of welding points on the base mold, there are no holes that can be pierced, thus preventing leakage from the welding points.

           EightApplication Solutions:

                      High-rise, high-rise structure

                              High-rise buildings and structures not only have stringent requirements for structural quality but also have special demands for project timelines and on-site safety. Reinforced truss deck plates offer both construction templates and load-bearing capabilities simultaneously.                          Reinforcement steel"Dual Role"High-rise and super high-rise construction projects can fully leverage our advantages. Reinforced truss floor decks are used in high-rise buildings, enabling multiple relatively independent and safe work surfaces.                        Enhanced construction progress.

                      Bi-directional panel structure

                               Compared to corrugated steel sheets, designing and constructing bidirectional panels is highly advantageous for reinforced steel truss floor decks. Without increasing the floor thickness, reinforced steel truss floor decks can be installed on-site                           Double-reinforcement can easily meet the design requirements of a two-way slab.

                     Large-span structure (with support solutions)

                             In large-span applications, to save costs, light-gauge steel joist deck can be used. During construction, before pouring concrete, simple temporary supports are set at the mid-span of the floor.                       Supports are designed to meet construction requirements while also protecting the floor's strength to the required level upon reaching the operational stage.

                     Large-span structure (no support solution)

                              Steel truss floor decks, with their technically rational mechanical design, can achieve by appropriately adjusting the steel bar specifications.5mUnsupported large plate span design requirements. In practical application, it can accelerate the construction process.                        Streamline production and save construction costs.

                      Thick plate design

 For300mmAbove-grade slabs can be designed with reinforced truss deck to reduce or eliminate temporary supports, thereby accelerating construction progress.

                       The use of steel truss floor decks in multi-story reinforced concrete structures can reduce the labor required for on-site formwork installation and dismantling, decrease on-site manpower, and greatly accelerate the progress of the project.

                      Reinforced concrete or steel frame residential projects

                              This type of structure typically requires a high standard of finishing for the floor slab bottom, necessitating plastering work and the use of multi-dimensionalTDDDetachable steel truss floor deck assembly can effectively address                          This challenge meets the requirements for construction speed in steel structure projects and also allows for the removal of the bottom form after the floor construction is completed, achieving a satisfactory decorative effect.

                      Circular, Elliptical, Other Shapes

                                These types of structural floor slabs are typically designed as two-way slabs, not only bearing vertical loads but also horizontal tensile forces; in addition, due to the irregular shape of the structure, the support issues for floor construction are often...                         Difficulties in construction can be effectively addressed by using reinforced truss deck slabs.

                      Sloped roof structure

   For sloping roofs, reinforced truss deck panels can be used for roof sheeting. The deck panels can be laid along the slope or parallel to it, both are feasible. The roof must be properly treated for stable performance.
