Filler slab roof construction.

Filler slab roof construction.

Reduction in concrete and steel reduces the generation of carbon which in turn makes the slab construction eco friendly. 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. Filler slab technology is a simple and a very innovative technology for a slab construction. The air gap in between the tiles makes it a good heat insulator.

One way to make a boring and expensive concrete slab sexy lighter and cheaper is to use a filler slab. A filler slab is where we replace a portion of concrete in the tension zone of the slab with inexpensive lightweight filler materials such as clay roof mangalore tiles bricks earthen pots coconut shells glass bottles or any other creative material you can think of. Once the shuttering is done the reinforcements are laid in grid form. The filler slabs also result in fewer loads getting transferred to the load bearing walls and the foundations.

Filler slab with terra cotta pots as fillers. A filler slab roof using clay pans. 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 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.

Advantages of filler slabs. The most popular filler material is the roofing tile. 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. 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.

The size of grid depends on structural design and size of filler material. The filler material thus is not a structural part of the slab. By reducing the quantity and weight of material the roof become less expensive yet retains the strength of the conventional slab. 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. If done with proper workmanship the filler. 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. Concrete is very good in withstanding compressive forces and steel bears the load due to tensile forces.
