I. Overview of Steel Reinforced Truss Deck

　　                 Reinforced truss floor deck is a composite formwork that involves processing the steel rebar into a truss structure in a factory and then welding the truss with galvanized corrugated steel as the base formwork into a single unit. During the construction phase, the steel rebars are...

                The truss floor deck can bear construction loads and is directly laid on beams for simple steel reinforcement work before concrete pouring. As it completely replaces the formwork function, it reduces the need for formwork installation and dismantling labor.

                The process greatly enhances the efficiency of floor construction.A value-enhancing floor deck product,We have eliminated factors that contribute to the increase in material costs.,Change the usage of the pressed steel plate to only serve as a floorboard

               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 deck sheet during the construction phase.,During the construction phase by corrugated

               Steel plate stiffness is now provided by reinforced trusses, enabling greater floor deck stiffness to accommodate larger unsupported floor spans. We have reduced the cost of customers' post-maintenance expenses.,Pressure                 

               Sheet steel, only used as a formwork during the construction phase, requires no treatment for performance stability and does not need to meet the requirements of the building's service life, thus no consideration for maintenance costs is necessary.

　　(1)Economic

The steel truss has a reasonable load-bearing pattern, cost-effective material selection, and obvious advantages in overall cost.

Adjustable truss height and rebar diameter to suitetFlooring for wide spans

The truss load-bearing pattern can offer greater deck stiffness for floors, significantly reducing or eliminating the need for temporary supports.

　　(3)Safety

Mechanical properties are similar to those of traditional cast-in-place floor slabs, with excellent crack resistance.

Fire resistance is comparable to traditional cast-in-place floor slabs and superior to composite steel deck floor slabs.

The mold base is not in use during the force-bearing stage, so there is no need to consider fire resistance and corrosion prevention issues.

Floor Deck Product Development History

     Section 3:TDV、TDMIntroduction to Type Steel I-Beam Truss Floor Deck

                TDV、TDMA type steel truss floor deck involves processing the steel reinforcement in the factory into steel truss shapes, then welding these trusses together with galvanized steel sheet bottom molds to form an integrated composite template.                    During the construction phase, steel truss deck can bear construction loads directly laid on beams, and concrete can be poured after simple reinforcement work. As it completely replaces the formwork function, it reduces the board...           Erecting and dismantling projects have significantly enhanced the efficiency of floor construction.

              Excellent weld joint load-bearing capacity

             "M"Type upright rib width reaches2-3mm, the weld point bearing capacity of the steel rebar web stiffeners is approximately the same as that of ordinary"V"L-shaped ribbed plate weld joint load-bearing capacity1.5 Multiple.

              Good 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 exhibiting superior corrosion resistance.TDV Steel truss floor deck, eliminates the possibility of maintenance later on.

              Avoid slippage

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

           EightApplication Solutions:

                      High-rise, high-rise structure

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

                      Bi-directional board structure

                               Compared to corrugated steel sheets, designing and constructing a bidirectional deck scheme is highly advantageous for reinforced steel truss floor decks. Without increasing the thickness of the floor deck, reinforced steel truss floor decks can be installed on-site                           Reinforcing in both directions is easily achieved, making it simple to meet the design requirements for two-way slabs.

                     Large-span structure (with support solutions)

                             In large-span applications, to save costs, light-gauge steel joist deck slabs can be used with smaller diameter steel bars. During construction, simple temporary supports should be set in the middle of the floor span prior to pouring concrete.                       Supports are in place to meet construction requirements and simultaneously protect the floor's strength to the required level upon reaching the usage stage.

                     Large-span Structure (No Support Solution)

                              Reinforced truss deck for steel girders, thanks to its technically rational mechanical design, can achieve by appropriately adjusting the steel bar specifications.5mUnsupported large plate cross design requirements. In practical application, it can accelerate the implementation.                        Improved work progress, cost-saving in construction.

                      Thick plate design

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

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

                      Reinforced concrete or steel frame residential projects

                              This type of structure typically requires a high finish on the floor slab surface, necessitating a plastering project, employing multi-dimensionalTDDAssembled removable steel truss floor deck can effectively address                          This challenge meets the demand for construction speed in steel structure projects while also allowing the removal of the bottom form after the floor construction, achieving a satisfactory finish.

                      Round,椭圆形,Other shapes

                                These 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 often arise.                         Challenges in construction are numerous, but the use of reinforced steel truss floor slabs can effectively address these issues.

                      Sloped roof structure

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