The thickness of the concrete floor of the factory floor is carefully calculated by the investor because most of the movement of goods and materials within the factory is carried out throughout. If not properly constructed, it is easy to damage and repair cannot be completely overcome.
Construction of concrete floor slab thickness is selected in the construction of prefabricated factories. Because of its super light features, it has many advantages and is simple in structure.
Desk floors are also known as decking floors, composite floors or ultra-light concrete floors, which are made up of reinforced concrete and concrete poured on corrugated board with embossed patterns manufactured into grooves at regular intervals. The floating tread allows the concrete to bond with the metal as the concrete hardens.
During the construction process, the concrete slab thickness is calculated to bear all kinds of loads due to the self-weight of wet concrete, reinforcement mesh, concreting equipment and operators. The floor is linked on the steel structure beam system by welding nails, which replaces the floor and load-bearing formwork with the reinforced concrete floor to help save construction time than the traditional reinforced concrete floor.
Cost savings and reduced construction costs thanks to the production according to design drawings, significantly reducing the amount of concrete and reinforcement thanks to the corrugated iron grooves.
The deck concrete thickness is enough to withstand the appropriate weight for any project requiring concentrated loads. The deck has a light steel grid system reinforced inside the concrete layer to withstand the external load.
High durability and aesthetics, light load compared to other materials, helps reduce load pressure. Optimizing auxiliary materials. Make the most of your factory space.
Fire resistance depends on the thickness of the concrete floor used, but the fire resistance time is different.
Construction of a concrete deck, the main component is a composite deck consisting of 4 main parts: deck corrugated board, floor slab mesh, deck anti-cutting nails.
+ Deck floor panels: hot-rolled galvanized steel. In order to create a wide surface that covers the entire other part of the frame, these corrugated iron sheets will be connected by connecting bolts. The surface of the floor will be roughened to increase adhesion when pouring concrete. Using corrugated iron has the effect of completely replacing formwork during construction, minimizing scaffolding to support.
The deck corrugated iron sheet is different from the usual roofing sheet in that there are embossed and convex patterns so that the concrete can adhere deeply to the corrugated iron.
+ Welding nails (deck cutting nails)
Consists of three parts including hat, body and solder beads. In order not to spread the arc and shoot back up, the nail is equipped with an external ceramic ring. It is responsible for connecting the corrugated board with steel beams. Welding nails help concrete blocks poured on the floor do not slide on the floor surface. Help the concrete floor slab frame system to be linked into a unified whole.
+ Steel mesh deck deck
Is a layer of steel woven according to technical standards that has the effect of binding fresh concrete and limiting shrinkage of the concrete floor. This is the main bearing structure when combined with concrete. It bears the entire load acting directly on the floor.
+ Concrete: Depending on the needs used for the construction of this concrete layer, there are different thicknesses and the usual concrete grade for the factory floor is M250 or M300. Shelf with steel frame and reinforced concrete is the main bearing structure to bear all kinds of loads on the floor.
During the design of the deck, engineers carefully calculated the load acting on the floor and the size of the floor cells. From there, the parameters of the auxiliary distance, the thickness of the concrete layer and the concrete mark, the specifications of the floor steel, the distance from the welding nails, the distance of the nails can be selected. Deck slab thickness, deck design must be done by structural engineers with heavy loads.
The deck plates are placed in the correct position on the steel communication system and connected to the shaped steel beam system with suitable welding nails. The welding nail gun will sell welding nails, then spread a layer of steel floor from 150mm-200mm distance and pour concrete.
With the construction solution of reinforced concrete thickness, it helps to speed up the construction time because it is optimized. Moreover, this solution also allows concreting multiple floors at the same time without having to wait for the formwork to be removed like traditional floor construction solutions with wooden and iron formwork.
This solution optimizes the components to reduce the weight of the material and reduce the load on the foundation, leading to a reduction in the overall cost of the building.
During the construction process: the slab costing the deck is considered as the formwork. Calculated to be able to withstand the loads of the concrete weight, the construction load includes the weight of workers and concrete pouring equipment. Cases of floor impact or vibration should be taken into account. Load due to material for temporary storage. Construction of standard decks is simple and quick, and needs to be closely monitored from preparation to construction.
The process of putting the deck into use: The deck's concrete thickness needs to be safe when subjected to loads, ensuring the allowable deflection. The load that should be noted is the load used depending on the functional requirements of the building, the weight of the deck itself is reinforced concrete and other additives. And many loads arise in the process of transporting machinery and goods in the factory.
