What is a shored slab?
Load-Bearing System Support for Concrete Slabs EFCO’s shoring systems aim to eliminate the need for reshoring and provide the lowest in-place concrete cost on elevated floor slabs. 50K-100K® ADJUST-A-DECK® EFCO DECK® E-Z DECK®
What does composite slab mean?
In structural engineering, composite construction exists when two different materials are bound together so strongly that they act together as a single unit from a structural point of view. When this occurs, it is called composite action. One common example involves steel beams supporting concrete floor slabs.
What are the types of composite construction?
Types of Composites in Construction
- 1: Polymer Matrix Composite.
- 2: Metal Matrix Composite.
- 3: Particulate Composite.
- 4: Flake Composite.
- 5: Fiber Reinforced Composite.
- 6: Laminated Composite.
- 7: Composite Structures.
- 8: Lightweight Bridge Constructed From Poltruded FRP Sections.
What is Unshored construction?
In unshored construction, the steel beams are not shored and designed with enough strength and stiffness in the pre-composite phase (before the concrete hardens) to support the weight of the wet concrete and any construction loads.
What is the difference between shoring and reshoring?
Shoring is removed once the concrete floor has gained adequate strength and, where applicable, the appropriate post- tensioning has been applied. Reshoring is utilized to distribute construction loads among several levels or to grade in order that the cast floors will not become overloaded and overstressed.
What are the types of shoring?
Here are several different shoring types that construction professionals use:
- H and I-beam shoring.
- Secant pile shoring.
- Contiguous pile shoring.
- Sheet piles.
- Diaphragm walls.
- Raking shoring.
- Hydraulic shoring.
- Soil nail shoring.
What are the four classification of composite?
Composites are usually classified by the type of material used for the matrix. The four pri- mary categories of composites are polymer matrix composites (PMCs), metal matrix compos- ites (MMCs), ceramic matrix composites (CMCs), and carbon matrix composites (CAMCs).
What is structural shoring?
Shoring is the process of temporarily supporting a building, vessel, structure, or trench with shores (props) when in danger of collapse or during repairs or alterations. Shoring comes from shore, a timber or metal prop. Shoring may be vertical, angled, or horizontal.
