I. Overview of Steel Reinforced Truss Deck
Reinforced truss floor deck is a composite formwork consisting of steel rebars processed into a truss structure at the factory, which is then welded together with a galvanized corrugated steel plate as the bottom mold. During the construction phase, the steel rebars...
The truss deck can bear construction loads and is directly laid on the beams, allowing for simple steel reinforcement work before concrete pouring. As it completely replaces the formwork function, it reduces the setup and dismantling of formwork frames.
The process significantly enhances the efficiency of floor construction.A floor deck product that enhances customer value,We eliminated factors contributing to the increase in material costs.,Change the usage of the shaped steel plate to only serve as floor deck
Templates during the construction phase, reducing the consumption of corrugated steel sheets, and lowering the requirements for the stable coating of corrugated steel sheet performance. We have altered the load-bearing mode of the roof deck during construction.,During the construction phase
Steel plate stiffness is now provided by reinforced trusses, allowing for greater floor deck stiffness to accommodate larger unsupported floor spans. We have reduced the costs for customers' post-construction maintenance.,Pressure
Type steel plate is solely used as a template during the construction phase and does not require treatment for stability. There is no need to meet the lifespan requirements for architectural use, hence there is no consideration for maintenance costs later on.
Section 2: Advantages of Steel Reinforced Truss Deck Plates
(1)Economic
Reinforced truss has a rational load-bearing pattern, economical material selection, and a significant cost advantage in total construction.
Adjustable truss height and rebar diameter for suitabilityetBoards for wide spans
Can be designed as a double-sided board
(2)Convenient
On-site rebar tying work volume can be reduced60%-70%Further shortening of the project timeline is achievable.
The truss loading pattern offers enhanced 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 for the floor.
The fire-resistant performance is comparable to traditional cast-in-place floor slabs and superior to composite steel deck floor slabs.
The bottom mold is not in use during the force-bearing phase, so there's no need to consider fire resistance and corrosion prevention issues.
(4)Reliable
Reinforcement bars are evenly arranged, with reliable guarantees for the spacing between layers and the thickness of the protective layer for the reinforcement.
Double discount edge overlap design, effectively ensuring the construction quality of composite floor assembly.
Steel reinforcement truss deckSimilar bidirectional stiffness benefits seismic resistance in buildings.
Screw钉welding quality is easier to ensure.

III.TDV、TDMProduct Introduction: Type Steel I-Beam Truss Floor Deck
TDV、TDMThe type steel truss floor deck involves fabricating steel reinforcement into a truss structure in the factory and then welding this truss to a galvanized corrugated steel sheet as the bottom mold, creating a combined formwork. During the construction phase, steel truss floor decks can bear construction loads and be directly laid on beams, allowing for simple reinforcement work before concrete pouring. As they fully replace the formwork function, they reduce the board... Engineering for installation and dismantling, significantly enhances the efficiency of floor construction.

Section 7:TDMAdvantages of Type Steel Beam Truss Deck:
Excellent weld point bearing capacity
"M"Type straight rib width reaches2-3mm, the weld point bearing capacity of the steel rebar web members in the steel truss is approximately equal to that of the ordinary"V"Type rib plate weld point load-bearing capacity1.5 Multiple.
Effective and stable performance
The distance between the steel truss and the welding point of the bottom form is approximately5mmThe bottom mold surface is free of weld points, will not produce rust spots, and has superior corrosion resistance.TDV Steel girder deck with type steel, eliminating the possibility of future maintenance.
Avoid leakage of paste
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.
TDMSteel girder deck applications
Suitable for cleanrooms without suspended ceilings, for environments with high requirements for indoor air quality such as laboratories, data centers, and machine rooms, and for applications where air humidity and salinity are concerned. High coastal city usage; buildings without suspended ceilings, exposed public structures; high-rise office buildings with superior quality sold directly before ceiling decoration.
TDVSteel girder deck for construction applications
For multi-story steel structural factories and public buildings with or without suspended ceilings, where the effect of the subfloor is not highly demanding.
EightApplication Solutions:
High-rise, high-rise structures
High-rise buildings and structures not only have stringent requirements for structural quality but also place special demands on project timelines and on-site safety. Reinforced truss floor decks offer the dual benefits of construction templates and load-bearing capabilities. Reinforcement steel"Dual Role"Our high-rise and high-rise construction services fully leverage their advantages. Reinforced truss floor slabs are used in high-rise buildings, creating multiple relatively independent and safe work surfaces. Enhanced construction progress.
Bi-directional panel structure
Compared to corrugated steel sheets, designing and constructing a two-way panel scheme is highly beneficial 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 it simple to meet the design requirements for two-way slabs.
Large-span Structure (With Support Solutions)
In large-span applications, to save costs, steel truss floor decks can utilize smaller size steel bars. During construction, before pouring concrete, a simple temporary setup is placed across the floor span. Supports are designed to meet construction requirements while also protecting the floor's strength to meet usage stage requirements.
Large-span structure (without support scheme)
Reinforced steel truss floor deck, with its technically rational mechanical design, can achieve appropriate adjustment of steel grades.5mUnsupported large plate span design requirements. In actual application, it can accelerate the implementation process. Efficient work progress, cost-saving in construction.
Thick plate design
For300mmAbove-thickness floor slabs can be designed using reinforced truss floor decks, allowing for thick slab construction. This can reduce or eliminate the need for temporary supports, thereby accelerating the construction progress.
The application of steel truss floor slabs in multi-story reinforced concrete structures can reduce the workload for on-site formwork installation and removal, minimize manual labor, and significantly accelerate the project进度.
Reinforced concrete or steel frame residential projects
This type of structure generally requires a high finish on the floor slab, necessitating a plastering project, employing multi-dimensionalTDDAssembled detachable steel truss floor deck can effectively address This challenge meets the requirements for construction speed in steel structure projects and also allows for the removal of the bottom formwork after the floor construction is completed, achieving a satisfactory finishing effect.
Circular,椭圆形,Other shapes
This type of structural floor is typically designed as a two-way slab, not only supporting vertical loads but also horizontal tensile forces; in addition, due to the irregular shape of the structure, the support issues during floor construction often Challenges in construction can be effectively addressed by using reinforced steel truss floor decks.
