A truss floor deck is a structural component used to support and distribute floor loads. It consists of multiple horizontal and vertical beams that form a framework structure, designed to bear the weight of the floor and transfer the loads to the supporting structure.
Truss floor decks are commonly made of steel or concrete. Steel truss floor decks offer high strength and rigidity, suitable for structures with large spans and heavy loads. Concrete truss floor decks provide good fire resistance and sound insulation, ideal for buildings requiring fire protection and noise reduction.
The design of truss floor decks must consider factors such as floor loads, spans, and the load-bearing capacity of the supporting structures. Depending on design and construction requirements, truss floor decks can be implemented in various forms and layouts, such as beam-and-slab structures, hollow slab structures, and so on.
Truss floor decks play a vital role in construction, effectively distributing and transferring floor loads to ensure the stability and safety of the building structure. Moreover, they offer flexible spatial layouts to meet various architectural functions and usage requirements.
Demountable steel truss floor deck construction is a common building method, suitable for temporary structures that require quick assembly, disassembly, or adjustment, such as exhibition halls, warehouses, and gymnasiums.
Construction steps are as follows:
Design: Dimensions, materials, and connection methods for truss structures and floor slabs are designed based on building requirements and load calculations.
2. Material Preparation: Prepare the required steel rebars, trusses, and floor deck materials according to design specifications.
3. Truss Installation: First install the main and secondary beams of the truss according to the design drawings, followed by the uprights and diagonal supports, ensuring the stability of the truss structure.
4. Rebar Binding: Lay the rebar on the floor slab according to design specifications and secure it to the truss using rebar binding tools.
5. Concrete Pouring: Set up the concrete formwork on the rebar and secure it to the truss with bolts. Next, pour the concrete into the formwork and use a vibrator to compact the concrete evenly.
6. Maintenance: After the concrete pouring is completed, it is necessary to carry out maintenance to maintain appropriate humidity and temperature to ensure the strength and stability of the concrete.
7. Demolition: When it's necessary to dismantle or adjust the floor slab, use tools to remove the formwork and progressively dismantle the truss structure.
In general, the construction method of removable steel reinforced truss floor deck is characterized by its fast construction speed, high flexibility, and reusability, making it suitable for situations requiring temporary structures.
