Metal deck is a steel structure building material produced by cold roll forming, which is used for supporting floor concrete in the construction industry. It is also called metal floordeck.
Metal deck classification: There are three kinds of metal deck: open metal decks, contracting metal decks and closed metal decks
Metal deck are widely used in power plant, power equipment company, automobile exhibition hall, steel structure factory building, cement warehouse, steel structure office, airport terminal building, railway station, stadium, concert hall, grand theater, supermarket, logistics center, Olympic stadium and other steel structure buildings.
Metal deck plate adapt to the requirements of the rapid construction of the main steel structure, can provide a firm working platform in a short time, and can be used to lay multiple floors of pressed steel plate, layered concrete slab water construction.
As the tensile reinforcement of concrete floor, the metal deck plate improves the stiffness of the floor and saves the amount of reinforcement and concrete.
Pressure plate surface has embossing between the metal deck plate and concrete to produce the maximum binding force, so that the two into a whole. Metal deck floor usually has stiffening rib, so that the floor bearing plate system has a high bearing capacity.
Under cantilever condition, metal deck plate is only used as permanent template. The length of the cantilever can be determined according to the section characteristics of the bearing plate. In order to prevent the crack of the cantilever plate, negative reinforcement should be provided at the support according to the design of the structural engineer.
Metal deck plate is divided into: open floor bearing plate, shrink mouth floor bearing plate, closed mouth floor bearing plate three generations of products.
Open floor bearing plate just as permanent floor template, unable to function together with the concrete, stress analysis is complex, so open floor bearing plate just as permanent template used in construction. When the strength of concrete reaches 75%, it does not have any positive effect. According to the budget department statistics, open floor bearing plate in engineering overall cost 1.6 times that of cast-in-situ construction cost.
Shrink mouth floor bearing plate: the engineers improve the plate type, the plate of the narrow opening, namely shrink mouth floor bearing plate, also known as the dovetail bearing plate. Not only can the plates and concrete work together, but also reduce the height of the concrete weakened area. Fire prevention and anti-corrosion of shrink mouth floor bearing plate have very big improvement and the stiffness is higher than the composite open floor bearing.
Closed floor bearing plate: engineers add shear groove on the original floor bearing plate surface, and make both of them bear force together through concrete coating on plate to increase the strength of floor plate, which can not only make floor bearing plate and concrete become a whole, but also save some tension reinforcement. Therefore, the cost of the project is greatly reduced.
