False Ceiling
In the case of framework of false ceiling, it must be sufficiently strong to take its own load plus the load of one or two workers to work on it. For designing the framework, it is necessary to consider the dead weight of all members of false ceiling and the span of space. First of all, framework is done. Generally this is done with the help of steel or wooden members depending on the span and the cost.
First the rafters are fixed depending on the structural requirement, then further it is divided into small areas depending on the available sizes of the materials to be fixed and the rigidity of substructure. Sometimes instead of angle iron, wooden buttons can be used for fixing the material.
Ceiling
In the case of soft materials again we need T or channel similar to wall lining to fix the material and if the span is longer and section of rafter is smaller than the rafters can be given hanging supports from the structural roof.
Nowadays fiber glass is used on a large scale for appearance and other purposes like artificial sky of a planetarium which is fixed directly with main structure with the help of some special carbohydrates gum-materials.
Sometimes gunny bags or clothes are stretched with the help of wires or ropes or even on the wooden frame depending on the span. The construction of frame for false ceiling also depends on the site conditions, materials available, requirement, cost and other members, available along with main structural members.
