A solid slab of concrete capping the top of your house.
Construction filler slab roof.
The filler material.
Here indigenous building materials are incorporated techniques that absorb and relate to other forms of design and materials.
2 construction technique the floor roof consists of a cast insitu rc filler slab with non autoclaved cellular concrete filler blocks as shown in fig.
Slab for floor and roof.
Exact specifications vary but most concrete roofs are several inches thick.
A concrete roof is exactly what it sounds like.
The filler slab is a mechanism to replace the concrete in the tension zone.
Filler slabs consume less concrete and steel as compared to conventional slabs due to the use of less heavy low cost filler material such as rejected calicut tiles clay pots and broken pieces of cement blocks.
This technical brief describe the technology of filler slab.
Filler slab roof construction.
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.
Slabs are constructed to provide flat surfaces usually horizontal in building floors roofs bridges and other types of structures.
The size of grid depends on structural design and size of filler material.
Concrete is very good in withstanding compressive forces and steel bears the load due to tensile forces.
The most popular filler material is the roofing tile.
For example the florida based company hurricane proof systems offers a 7 inch 18 centimeter slab of concrete in three layers.
A filler slab roof using clay pans.
Filler slab with terra cotta pots as fillers.
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.
By reducing the quantity and weight of material the roof become less expensive yet retains the strength of the conventional slab.
This concrete doesnt add to the strength of the slab as all the tension is taken up by the reinforcement rods.
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.
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 filler material thus is not a structural part of the slab.
1 the filler blocks are 110 mm thick and 260 x 560 mm at top tapering down to 250 x 550 mm at bottom.
The slab is cast with cement concrete of.
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.
