Common defects in flat rcc roofing slopes are not proper and lot of depression is existed on the surface where water is stagnated drip courses are not constructed according to required specifications.
Rcc roof construction.
The projecting portion of the slab is cantilever with free support on the masonry wall.
Broken tiles which create depression are used in tile tracing.
This roof type is easier to install over large surfaces and is the most common choice for commercial industrial and institutional buildings.
Concrete weighs a lot and the outside walls have to be capable of supporting the giant slab.
Precautions to be taken during construction of r c c.
Rcc roof slab in the construction industry when they use the word concrete they are talking about reinforced cement concrete also known as rcc.
Due to the structural condition the slab will have negative bending moment causing tension at the support on top.
Roof on masonry wall and projecting outside the building.
Construction of rcc design from start to end in step by step manner.
Of course a concrete roof requires more support than a typical wooden roof.
Interior support beams can help but the construction works best when concrete walls floor and roof form a solid shell.
The reinforced concrete features combined the strength of cement and steel bars which are the basic components of a modern structural design.
