Big slab installation

The reinforced big slab installation is an essential structural component and is utilized to create a surface that is flat (floors as well as ceilings) within buildings. The reinforcement offered by beams, beam support, as well as the ratio of lengths of the slab, is typically divided into one-way slabs as well as two-way slabs. They are supported by two sides, and their ratio from long span to short span is more than two. The latter, however, is supported by four sides, and the ratio of long span to short span is less than two.

The various conditions and conditions call for the selection of suitable and cost-effective concrete slabs, taking into consideration the kind of building and layout, architectural design aesthetics, features and span. Concrete slabs are further classified into types of Special Slabs Installer in the following manner:

1. Slabs on Beams Installation

The casting method is employed to build one-way slabs for beams that involve fixing the form and then installing reinforcements and then pouring fresh concrete.

One-way beams with slabs are suitable for spans of 3 to 6 meters and an operating load that is between 5 and 3KN for 2. They are also a good choice to span longer distances but at more expensive costs and greater slab deflection. A second formwork to support the beams is required.

2. Joist slab Installation (Ribbed slab)

It is comprised of a flooring slab typically 50-100mm thick, which is supported by concrete ribs that are reinforced (or Joists). The ribs are typically tapered and spaced at distances that don’t exceed 750mm. The ribs are held on girders which are supported by columns.

A one-way concrete slab can be used with spans of 6-9m as well as live loads of 4-6 KN/m 2. Due to the deep ribs that are a part of the slab, the concrete and steel quantities are comparatively low however costly forms are required.

3. Waffle Slab Installation (Grid slab)

It is a form of concrete slab reinforced consisting of square grids that have deep sides. The construction of waffle slabs involves fixing forms, placing pods on shuttering, and the installation on reinforcement in between the pods installing steel mesh over pods, as well as pouring concrete.

Grid slabs work well to span 9 to 15m as well as live loads of 4-7kN/m 2. Formwork and Pans are very expensive.

4. Flat Plates Installation

Flat plates can be built as two-way or one-way slabs and are supported by walls or columns. It is straightforward to construct and only requires simple formwork.

Flat plates are best suited for spans between 6 and 8m and live loads that range between three and five kilograms 2. Additionally, the spans for flat plates that are pre-stressed are between 8-12 meters and are also possible to build them in post-tensioned slabs.
