Ceiling framing is the construction of ceiling and ceiling construction begins when all walls have been aligned, plumbed and secured. One of the main functions of ceiling frame is splicing of outside walls of the building. Rafters are used to resist outward pressure placed on the walls. Joists are the most important element in framing of ceiling. One must know while selecting the products the span of joist i.e. clear distances between the supports. There are certain specifications which are considered while selecting rafters, and joists such as moment, reaction and shear capacity for normal load duration, deflection in terms of shear and bending deformation and live and dead weight.
Repair of rafters and joists is very expensive and time consuming process but with growing technology this has been possible with low cost as well because of timber resin splice called TRS. Timber resin splice is new technique which allows Low disturbance and cheaper repairs repair of beams, tie beams, lintels, joists and rafters. This method can even be used for repairing flag poles.
There are certain approved methods and formulas for calculating depth of joist for reducing it or increasing it. Usually a thumb rule is followed for calculating depth of joist .It is half the distance between supports plus 2 inches. E.g. The joist depth required for a 14-foot span is 9 inches. Band sill is another term for joist used by construction workers
There are different ways to do repairs of joists and rafters through this method .One is without removing sections of ceiling, repair of dry rot can also be done, repairing of splits and shakes, roof truss is also possible through this method.
