Filler Slab Roof Construction

Filler slab technology is a simple and a very innovative technology for a slab construction.

Filler slab roof construction. Hi sireesha the filler slabs will have similar load bearing capacity as only the concrete which is in the tension part of the slab is replaced by the filler material. A filler slab roof using clay pans. One way to make a boring and expensive concrete slab sexy lighter and cheaper is to use a filler slab. By reducing the quantity and weight of material the roof become less expensive yet retains the strength of the conventional slab.

Advantages of filler slabs. The most popular filler material is the roofing tile. Filler slab roof construction where inverted hemispheres of terra cotta pots are pre cast and made to rest over reinforced concrete beams before the concreting process. The filler slab is a mechanism to replace the concrete in the tension zone.

The filler slabs also result in fewer loads getting transferred to the load bearing walls and the foundations. For example grid of 35cm x 50cm is used for magalore tile as filler material and grid of 45cm x 45cm is used for clay pots of 40cm diameter filler. Here indigenous building materials are incorporated. The filler material thus is not a structural part of the slab.

The filler slab is based on the principle that for roofs which are simply supported the upper part of the slab is subjected to compressive forces and the lower part of the slab experience tensile forces. The size of grid depends on structural design and size of filler material. Once the shuttering is done the reinforcements are laid in grid form. Filler slab with terra cotta pots as fillers.

If done with proper workmanship the filler. Filler slab roof construction. 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. There is considerable saving in concrete and steel by adopting rcc filler slabs instead of conventional rcc solid slabs and approximate cost saving is rs 200 sqm.

Concrete is very good in withstanding compressive forces and steel bears the load due to tensile forces. If clay tile roof of a building is removed for constructing rcc slab roof the clay tiles can be reclaimed and can be used as filler material for. The air gap in between the tiles makes it a good heat insulator. Reduction in concrete and steel reduces the generation of carbon which in turn makes the slab construction eco friendly.
