Decking plates, also known as composite deck plates, floor plates, or steel deck plates, are a widely used structural material in the construction industry. They are formed by cold rolling and bending galvanized steel sheets, with cross-sections typically in V, U, trapezoidal, or similar wave shapes. Decking plates are primarily used as permanent formwork but can also be selected for other uses, such as being part of the reinforcing steel under the floor deck, contributing to the floor's load-bearing calculations, and working together with concrete to form composite deck plates.

I. Characteristics of Floor Decking

Adaptable: Floor deck panels can quickly accommodate the demands of rapid steel structure construction, providing a stable working platform in a short time. They support simultaneous laying of steel plates on multiple floors and layered pouring of concrete.

High load-bearing capacity: The roof deck can withstand significant pressure and shear forces, meeting the structural load requirements of buildings.

Durable: Made from high-quality steel and treated for corrosion and rust resistance, offering a long service life.

Ease of construction: Floor decks can be customized according to architectural requirements, featuring easy and quick installation, effectively shortening the construction period.

Economical: The price of the roof deck is relatively reasonable, catering to the budget requirements of various construction projects.

Two, the application of the floor deck

Decking plates are widely used in power plants, electrical equipment companies, car showrooms, steel structural factories, cement storage warehouses, steel structural offices, airport terminals, train stations, sports venues, concert halls, grand theaters, large supermarkets, logistics centers, and Olympic venues, among other steel structures. In these buildings, decking plates not only serve as long-lasting formwork but also act as load-bearing components for the floors, working in conjunction with concrete to enhance the overall load-bearing capacity and rigidity of the floors.

Section 3: Types of Floor Decking

Decking panels, categorized by their cross-sectional shapes and applications, come in various types such as open-web decking, solid-web decking, and rabbet-type decking (also known as dovetail-type decking). Different types of decking panels have distinct characteristics in terms of load-bearing capacity, construction difficulty, and cost-effectiveness, allowing for selection based on specific project requirements.

Four: Construction Key Points of Floor Slabs

Laying and Connection: The floor deck should be tightly connected to the steel beam during installation, with the end of the deck bonded to the beam at the fusion point, and intermediate sections connected using bolted penetration and fusion welding with the beam. The floor decks are joined using special clamping pliers to bite and press the holes, ensuring overall stability.

Concrete Pouring: When pouring concrete, it is important to avoid excessive concentration of material. Use a flat vibrator to evenly distribute the vibration promptly, ensuring a firm bond between the concrete and the floor deck.

Quality Control: During construction, stringent control over the quality of floor decks should be maintained, encompassing material quality, installation quality, and welding quality, to ensure that the floor decks meet design and usage requirements.
