I. Overview of Steel Reinforced Truss Deck

　　                 Reinforced truss floor deck is a composite template that involves processing the reinforcing steel in the factory into a steel truss and then welding the steel truss to the galvanized corrugated steel bottom mold as a single unit. During the construction phase, the steel reinforcing...

                Truss floor deck can bear construction loads, directly laid on beams, and simple steel reinforcement work is sufficient for concrete pouring. As it completely replaces the formwork function, it reduces the setup and dismantling of formwork frames.

                Process greatly enhances floor construction efficiency.A value-boosting floor deck product,We have eliminated factors leading to increased material costs.,Change the usage of the shaped steel plate to only serve as a floorboard

               Templates at the construction stage, reducing the usage of profiled steel plates and lowering the requirements for the stable coating performance of the profiled steel plates. We have altered the load-bearing pattern of the floor deck during construction.,During the construction phase, by molding

               Steel plate stiffness is now provided by reinforced trusses, offering increased floor deck stiffness to accommodate larger unsupported floor spans. We have reduced the costs for our customers' post-installation maintenance.,Pressure                 

               Hollow steel plate is only used as a formwork during the construction phase, and no treatment is required for its stability. It does not need to meet the lifespan requirements for building use, thus there's no need to consider maintenance costs later on.

The Evolution of Floor Decking Products

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

                TDV、TDMThe steel beam truss deck for floor slabs involves fabricating the steel reinforcement into a truss at the factory and then welding it into a single assembly with the galvanized pressed steel plate bottom mold.                    During the construction phase, steel truss floor decks can bear construction loads, be directly laid on beams, and concrete can be poured with simple reinforcement work. As they fully replace the formwork function, they reduce the board...           Erecting and dismantling projects, with superior quality, have greatly enhanced the efficiency of floor construction.

           EightApplication Solutions:

                      High-rise, high-rise structure

                              High-rise buildings and structures demand not only stringent quality standards for their construction but also have special requirements for the timeline and on-site safety. Reinforced truss floor deck panels simultaneously serve as construction molds and support systems.                          Reinforcement steel"Dual Role"Our products excel in high-rise and super high-rise construction, utilizing reinforced truss floor slabs in high-rise buildings, which can create multiple relatively independent and safe working surfaces.                        Enhanced construction progress.

                      Bilayer board 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                           Reinforcement in both directions is easily achieved, making the design requirements for two-way slabs straightforward.

                     Large-span structure (with support scheme)

                             In large-span applications, to save costs, light-gauge rebars can be used for steel truss floor decks. During construction, before the concrete pouring, simple temporary supports are installed in the middle of the floor span.                       Supports are designed to meet construction requirements while also protecting the floor's strength upon reaching the operational stage.

                     Large-span structure (without support solution)

                              Steel truss floor deck, with its technically rational mechanical design, by appropriately adjusting the steel bar type, can achieve5mDesign requirements for unsupported large plate spanning. In practical application, it can accelerate implementation.                        Streamline production processes, save on construction costs.

                      Thick plate design

 For300mmThe above-thickness slabs can be designed using reinforced truss deck panels, which can reduce or eliminate the need for temporary supports, thereby accelerating the construction progress.

                       The use of steel truss floor slabs in multi-story reinforced concrete structures can reduce the amount of work for formwork installation and removal on-site, decrease on-site labor, and significantly accelerate the progress of the project.

                      Reinforced concrete or steel frame residential projects

                              Such structures typically have high requirements for the finishing effect on the floor slab bottom, necessitating a plastering project, employing multi-dimensionalTDDAssembled removable steel truss floor deck can effectively address                          This challenge meets the requirement for construction speed in steel structure projects, while also allowing for the removal of the bottom form after floor construction, achieving a satisfactory finish.

                      Round, Elliptical, Other Shapes

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

                      Pitched roof structure

   For sloping roofs, reinforced truss deck panels can be used for roofing. The deck panels can be laid along the slope or parallel, both are feasible. The roof must undergo stable performance treatment.
