How far can concrete decking span?
Reinforced concrete allows a wide range of structural options and provides cost-effective solutions for a multitude of situations—from residential buildings with moderate live loads and spans of about 25 ft, to commercial buildings with heavier live loads and spans ranging from 40 ft to 50 ft and beyond.
What is deck in steel structure?
What is Steel Deck? Steel Deck is a cold formed sheet of corrugated steel supported by joists or beams of steel. It is used for supporting a roof’s concrete or insulating membrane. It was developed to provide the roof and floor systems with a structurally efficient product.
Which is an advantage of metal composite slab with concrete?
Resistance/Weight ratio; greater resistance with lese weight, thus enabling a global reduction of the structure’s weight. The minimum slab edge measures a mere 12 cm. Quick installation; the absence of props means that more than one floor can be concreted at the same time, thus reducing construction time per floor.
How do you calculate concrete for a metal deck?
How to calculate concrete:
- Determine how thick you want the concrete.
- Measure the length and width that you’d like to cover.
- Multiply the length by the width to determine square footage.
- Convert the thickness from inches to feet.
- Multiply the thickness in feet by the square footage to determine cubic feet.
How much weight can steel decking hold?
Strength & Weight Steeldeck® platforms have a very good strength-to-weight ratio. A 4′ x 8′ Steeldeck® platform weighs approximately 150 lbs and supports an evenly distributed load of more than 4,000 lbs.
What are the advantages of steel decking floors?
Advantages of Metal Decking:
- #1 – Less Weight: Slabs made with steel decking have high structural strength compared to traditional concrete slabs.
- #3 – Easy Handling:
- #4 – Easy Installation of Shuttering Material:
- #5 – High Strength:
How is concrete poured on a metal deck?
The structural design and fire rating of the floor assembly dictates the concrete density, strength, and slab thickness. Commonly, concrete is placed utilizing a truck-mounted pump to convey the concrete up to the elevated slab where the concrete is placed on the corrugated metal decking.
What kind of deck is used for concrete slab?
Composite floor deck is a corrugated metal deck that has embossments in the flutes of the metal decking. As the concrete slab cures, the metal deck and the concrete bond together to create a composite metal floor deck. This is the most common type of metal floor decking.
How much does concrete weigh on a metal deck?
Concrete is placed on an elevated floor metal deck. Concrete placed on metal decks (Figure 1) is either normal weight concrete, typically weighing from 145 to 155 pounds per cubic foot, or lightweight concrete, typically weighing 110 to115 pounds per cubic foot.
What kind of flooring is used on metal deck?
One of the most common floor systems used in multi-story commercial construction is concrete placed on metal decking. The concrete is typically covered with some type of flooring material based on the building’s end use. The floor covering is adhered to the concrete with one of many readily available flooring adhesives.
