Shop by Product. 1.5CD, 1.5CDI Composite Deck Both … It also must evaluate three separate load combinations: (a) the dead weight of concrete and steel deck plus a 20 pound per square foot (psf) uniform construction live load, (b) the dead weight of concrete and steel deck plus a 150 pounds (lb.) Therefore, there are two main structural functions to be considered for the design of composite decks; (a) design the steel deck as a form to support construction loads, and (b) design the composite slab for superimposed floor loads after the concrete hardens. Cordeck Composite Floor Deck is used to create a steel/concrete composite floor in steel frame construction. Studwelders Composite Floor Decks Ltd. provides dedicated distribution, design and installation for steel floor decking systems throughout the UK. However, the design of the steel deck to serve as a form is usually more critical than the design of the composite floor to support superimposed floor loads. Composite floor decks have embossments that grip the concrete slab and they are typically reinforced with rebar or wire mesh which creates a strong bond with the concrete floor. Composite Metal Floor Deck: Side Lap Types. Cutting the deck before the concrete is poured and cured reduces the flexural capacity of the deck and can induce excessive deflection.

Note that, for the design of small or medium openings, location and spacing of the openings should also be considered. It combines exceptional spanning capabilities with reduced concrete usage to provide a cost-effective and attractive floor solution that is easy to install. This can lead to concrete ponding during construction. KS FlorDek50. Civilax is the Knowledge Base covering all disciplines in Civil Engineering. The main benefit of a composite deck is that it can be installed quickly, and is both efficient and effective. The design of composite steel deck-slab systems reflects the engineering concepts used to design reinforced concrete beams. It is highly recommended to leave the steel deck intact until the concrete has cured. Typically, openings are created by core-drilling the concrete floor or setting sleeves to create an opening before concreting. That is because the beams, deck, and concrete will act together structurally. However, cutting out the slab before the concrete is cured can prevent the deck from properly acting as a form. Due to the potential safety issues in cutting the deck, check with your local regulations and project requirements before proceeding. KS FlorDek75. The decking not only acts as a permanent formwork to the concrete but also provides sufficient shear bond with the concrete so that, when the concrete has cured, the two materials act together compositely to resist the loads on the deck. Composite deck is a similar product to roof deck and is a fluted steel sheet, 38 mm or 76 mm deep. Each quote for composite floor deck is based on: The specific composite deck chosen Number of sheets or sq. concentrated load per foot width of the deck, and (c) the dead weight of steel deck plus not less than 50 pounds per square foot (psf) uniform construction live load. Due to the complexity of the design procedures of composite floor decks, deck manufacturers usually provide tables summarizing permissible loads, section properties, maximum unshored spans, superimposed loads, and diaphragm shear loads. It serves as a form during the construction phase while the concrete is poured and cured and serves as reinforcement to act compositely with the concrete to support the floor loads.

This design must meet the minimum design loads specified in the American National Standards Institute’s and the Steel Deck Institute’s Standard for Composite Steel Floor Deck-Slabs, ANSI/SDI C-2017. However, these tables consider the deck as a solid uniform platform with no openings or penetrations. คุณสมบัติเด่น. An associated increase of the dead load on the deck may result from additional concrete poured to provide a level floor elevation. However, when the groups of openings run parallel to the bearing direction of the deck, the width of the opening can be considered as the width of a single hole (Figure 7). When the group of small or medium openings runs perpendicular to the span of the deck, the width of the hole should be considered to be the overall length along the string unless there is adequate deck remaining between the holes. Our directly employed self-sufficient installation and studwelding teams are extensively trained and highly mobile to ensure a rapid and efficient response to customers’ needs.
