What are the advantages of closed-type floor slabs?

　　The so-called closed floor decking is actually a steel plate that can support concrete. It is also known as floor decking steel plate or closed laminated plate.Closed floor deckingThere are three types: one is open type, and the other is closed type. Its characteristics include quick installation and adaptability to the main steel structure. The layered pouring method can improve construction speed through a continuous flow.Closed floor deckingWhat is the specific construction method?

　　1.Closed floor deckingDuring the construction of the supporting plate, first snap lines to determine the main control line at the centerline of the steel beam, then overlap the steel beam according to the control line to determine the position of the welding points. Next, set the position of the main beam according to the design requirements and make proper markings.

　　2. Then, proceed toClosed floor deckinghoist various steel plates to the site and stack them neatly before installation.

　　3. When installing the closed floor decking, the installation direction should be determined, and it should be arranged strictly according to the drawings and specifications. At the same time, the floor decking needs to be cut, then welded and fixed, while concrete is poured on its surface.

　　4. During the pouring process of the floor decking, care should be taken to avoid leakage issues. Welding nails should be used to weld both sides of each steel plate to prevent loosening. When pouring concrete, attention should be paid to ensure that the piles are not too high, as this may have certain impacts. Afterwards, the project should be checked to see if it meets the load-bearing requirements.

　　As a type of supporting plate, closed floor decking can increase the height of the floor and save the amount of concrete poured. When pouring closed floor decking, it is necessary to snap lines first, then transport it. After transportation, it needs to be cut and pressed, and the unnecessary parts should be processed. It is important to note that during the construction process, rebar, embedded parts, and concrete should be laid in advance to ensure the fastening effect of the floor decking and avoid loosening later.

　　During the usage phase, closed floor decking serves as the tensile rebar for concrete floors, which also increases the rigidity of the floor and saves the amount of rebar and concrete. Made from galvanized plates, the galvanized plate is a load-bearing plate with a thickness of 0.7-1.5mm, characterized by not requiring formwork, and no need for removal and installation of formwork, which can save tensile rebar in concrete floors and provide a flat ceiling surface for concrete floors.

　　Additionally, the embossed surface of the profiled plate can create a significant bonding force between the closed floor decking and the concrete, forming an integral whole, primarily enhancing the load-bearing capacity of the closed floor decking system. Furthermore, care must be taken when placing the closed floor decking during lifting to avoid collisions, preventing any changes to the closed floor decking. The unloading and hoisting of closed floor decking should be done using special lifting frames made of angle steel or channel steel and soft slings, and steel cables should not be used to directly lift the closed floor decking.
