Ribbed Floor Slab Definition

Sandwich slab reinforcement details in reality sandwich slabs are ribbed slabs with a slab placed both to their upper and lower surface.

Ribbed floor slab definition. The spacing between the ribs should be in general 20 30 inch. Ribbed slabs are made up of wide band beams running between columns with narrow ribs spanning the orthogonal direction. Waffle slabs tend to be deeper than the equivalent ribbed slab. Slabs are classified into 16 types.

Ribbed slab is a type of reinforced concrete slabs in which some of the volume of concrete in the tension zone is removed and replaced with hollow blocks or left as voids. Ribbed or waffle slab is a slab system which consists of series of parallel reinforced concrete t beams framing into reinforced concrete girders. Verb used with object ribbed rib bing. Also called building tile structural terra cotta hollow tile and clay block the material is an extruded clay shape with substantial depth that allows it to be laid in the same manner.

A vertical raised strip in eg knitted material or the pattern formed by a row of these. A waffle slab or two way joist slab is a concrete slab made of reinforced concrete with concrete ribs running in two directions on its underside. This form of construction is not very common because of the formwork costs and the low fire rating. This reduction in the volume of concrete in the tension zone below the neutral axis is based on the assumption that the tensile strength of concrete is zero hence all the tensile stress is borne by the reinforcements in the tension zone.

To furnish or strengthen with ribs. Between the ribs the slab is usually reinforced with a common wire mesh. The slab may be supported by walls or by reinforced concrete beams usually cast monolithically with the slab or by structural steel beams or by columns or by the ground. The name waffle comes from the grid pattern created by the reinforcing ribs.

Slabs are constructed to provide flat surfaces usually horizontal in building floors roofs bridges and other types of structures. Structural clay tile describes a category of burned clay building materials used to construct roofing walls and flooring for structural and non structural purposes especially in fireproofing applications. The slab is the flange of the beam and the extended part is the web. Normally the ribs and the beams are the same depth.

Ribbed floors consisting of equally spaced ribs are usually supported directly by columns they are either one way spanning systems known as ribbed slab or a two way ribbed system known as a waffle slab. To enclose as with ribs. A thin topping slab completes the system.
