I. Overview of Steel Reinforced Truss Deck

　　                 Reinforced truss floor decks are a composite template formed by processing the steel rebars in the factory into steel truss structures and welding them together with galvanized corrugated steel sheet molds. During the construction phase, the steel rebars...

                Joist deck girders can bear construction loads, be directly laid on beams, and simple steel reinforcement work is sufficient for concrete pouring. As they completely replace the formwork function, they reduce the need for formwork installation and dismantling labor.

               Templates during the construction phase, reducing the amount of corrugated steel sheet used, and lowering the requirements for the stable plating performance of the corrugated steel sheet. We have altered the load-bearing pattern of the deck sheet during construction.,During the construction phase by corrugated

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

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

Double discount edge lap design, effectively ensuring the construction quality of composite flooring.

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

Screw pin welding quality is easier to ensure.

Roof Decking Product Development History

     Section 3:TDV、TDMProduct Introduction: I-Beam Truss Floor Deck

                TDV、TDMA type steel truss floor deck involves fabricating the steel reinforcement into a truss at the factory and then welding it to the zinc-coated steel sheet bottom mold, creating a combined formwork.                    During the construction phase, steel truss deck can bear construction loads and be directly laid on beams, with only simple reinforcement work required to pour concrete. As it fully replaces the formwork function, it reduces the board...           Erecting and dismantling projects, with excellent improvements, have enhanced the efficiency of floor construction.

              Prevent leakage of paste

              Since there are no welding points on the base mold, there are no holes that can be焊接through, preventing any leakage of the welding material.

              TDMApplications for Type Steel Truss Deck Plates

                     Can be used in high-purity factory buildings without suspended ceilings, in laboratories, computer rooms, information centers, etc. with higher requirements for indoor air quality, and in environments with specific humidity and salinity levels.                 High coastal city usage; buildings without suspended ceilings, exposed public structures; high-rise office buildings of superior quality sold directly before ceiling decoration.

                       For multi-story steel structures with little demand for ceiling effect, or for public buildings with suspended ceilings.

           8Application Solutions:

                      High-rise, high-rise structure

                              High-rise buildings and structures not only demand strict quality standards for their construction but also have specific requirements for project timelines and on-site safety. Reinforced truss floor decks offer the dual functionality of construction templates and load-bearing capabilities.                          Reinforcement bar"Dual Role"High-rise buildings utilize reinforced truss deck plates, which enable the creation of multiple relatively independent and safe working surfaces, maximizing advantages in high-rise and super-high-rise construction.                        Enhanced construction progress.

                      Bi-directional board structure

                               Compared to corrugated steel sheets, designing and constructing bidirectional panels is highly beneficial for reinforced steel truss floor decks. Without increasing the floor thickness, reinforced steel truss floor decks can be installed on-site                           Tie reinforcement in both directions, making it easy to meet the requirements of two-way slab design.

                     Large-span structure (with support solutions)

                             In large-span applications, to save costs, the steel truss floor deck can use smaller-sized steel rebars. During construction, a simple temporary setup is placed in the middle of the floor span prior to pouring concrete.                       Supports are provided to meet construction requirements while also ensuring the floor strength meets the usage stage requirements.

                     Large Span Structure (Without Support Scheme)

                              Steel truss floor deck, thanks to its technically rational mechanical design, by appropriately adjusting the steel bar specifications, can achieve5mUnsupported large panel cross design requirements. In practical application, it can accelerate implementation.                        Efficient work progress, cost savings in construction.

                      Thick plate design

 For300mmAbove-thickness floor slabs can be designed using reinforced truss floor decks to reduce or eliminate temporary supports, thereby accelerating the construction progress.

                       The use of steel truss floor slabs in multi-story reinforced concrete structures can reduce the workload for on-site formwork installation and removal, minimize labor costs, and significantly accelerate the project timeline.

                      Reinforced concrete or steel frame residential projects

                              Such structures generally have higher requirements for the decoration effect of the floor slab bottom surface, necessitating plastering work and employing multidimensionalTDDDetachable steel truss deck assembly 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 finishing effect.

                      Circular, 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, the support issues for floor construction often arise.                         Difficulties in construction can be effectively addressed by using steel truss floor deck.

                      Sloped roof structure

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